SUMMARY
At the August 20, 2024, City Council Meeting, the City Council held a public hearing
related to Architectural Design Review No. ADR 23-13 with a density bonus and
Conditional Use Permit No. CUP 23-09 to amend a project that was previously approved
by the City Council in 2020. The revised project, known as “The Ivy Arcadia”, proposes a
three-story senior assisted living care facility with 100 units and 114 beds at 1150 W.
Colorado Boulevard. The revised project also includes a density bonus to allow a Floor
Area Ratio (“FAR”) of 0.88, which exceeds the maximum permitted FAR of 0.50. After
hearing testimony from the Applicant and the public, the City Council voted 4-0 to continue
the item to the September 17, 2024, City Council Meeting to allow the Applicant time to
schedule a meeting with the neighboring property owners and discuss the project.
A community meeting was held on September 4, 2024, and as a result several
modifications were made to the project. It is recommended that the City Council approve
Architectural Design Review No. ADR 23-13 with a density bonus and Conditional Use
Permit No. CUP 23-09 along with the new modifications proposed.
BACKGROUND
The applicant is requesting to demolish the existing 13,088 square foot restaurant building
on site and construct a new 107,706 square foot, three-story Traditional/Cape Cod
1150 W. Colorado Boulevard – The Ivy Arcadia
September 17, 2024

architectural style building that will provide assisted living and memory care services for
seniors that have Alzheimer’s and other related memory loss. The facility will have 100
units of various sizes with a total of 114 beds and will provide 24-hour staff services. At
the June 11, 2024, Planning Commission Meeting, the Planning Commission voted 3-0,
with two Commissioners absent, to recommend denial of the proposed project to the City
Council. The Planning Commission determined that the project was not compatible with
the adjacent neighborhood in terms of scale and height. For more information on the
project and this item, refer to Exhibit “C” for the complete August 20, 2024, City Council
staff report, including all attachments.
DISCUSSION
On September 4, 2024, the Applicant held a community meeting with the neighboring
property owners to discuss the project proposal and receive feedback on the issues that
the residents had concerns with. A total of 18 people attended the meeting. The Applicant
provided a summary of all the comments and questions they had received for the project
to date and provided responses to each of those comments. A lighting plan was presented
to indicate that the Applicant was in compliance with the City’s lighting requirements that
prevent glare from going to adjacent properties. The residents were also provided with
new diagrams and renderings prepared by the Applicant that illustrated the proposed
setbacks to each of the levels of the building in relation to the adjacent property lines.
Additionally, the block wall between the subject property and the neighboring residential
properties was analyzed to determine improvements that needed to be made to the wall.
The Applicant has proposed the following modifications to the project site as a result of
their community meeting and since the last City Council Meeting:
1) The Applicant has indicated that they will be relocating the trash enclosure from
the rear of the property after receiving concerns from the neighbors about its
proximity to the residential properties. The Applicant is now proposing to locate the
trash enclosure along the southwest portion of the site adjacent to Michillinda
Avenue.
2) After neighbors asked for a potential increase in the rear yard setback, the
Applicant removed some common area space within the building to increase the
rear yard setback of the building at its closest point to the neighboring properties
by 2’-4”, for a total rear yard setback of 37’-4”.
3) The Applicant has enhanced the landscaping by providing more trees and shrubs
on site as screening vegetation. The number of new trees on site was increased
from 83 new trees to 140 new trees. A total of 86 of the trees will be located in the
areas between the proposed building and the property lines for added privacy and
screening. The remaining trees will be dispersed throughout the rest of the site.
Refer to Exhibit “B” for revised drawings and diagrams that show the proposed
changes proposed by the Applicant.

These proposed modifications have been reviewed by the Staff and it has been
determined that these are positive changes that will create a better site plan in relation to
the neighboring properties and improve privacy.
RECOMMENDATION
It is recommended that the City Council make the required findings and adopt Resolution
No. 7572 and approve Architectural Design Review No. ADR 23-13 with a density bonus
and Conditional Use Permit No. CUP 23-09 and adopt the Addendum to the adopted

COLORADO BOULEVARD
WHEREAS, on November 9, 2023, applications were filed with the City of Arcadia
(“City”) for Architectural Design Review No. ADR 23-13 with a density bonus and
Conditional Use Permit No. CUP 23-09 were filed by O&I Development, LLC (“Applicant”)
on behalf of Artis Senior Living, LLC (“Property Owner”) to revise the project that was
approved by the City Council on August 18, 2020 (Resolution No. 2372) which was for an
assisted living care facility (known as Artis Senior Living Project) or the “Approved
Project.” The Revised Project, known as “The Ivy Arcadia” is for a two-story development
that is approximately 107,706 square feet with 100 units and 114 beds at 1150 W.
Colorado Boulevard. The Revised Project also includes a density bonus to allow a Floor
Area Ratio (“FAR”) of 0.88, which exceeds the maximum permitted FAR of .50. The
Revised Project is a senior housing development under the State’s Density Bonus Law
and is entitled to exceed the otherwise maximum FAR since it would physically preclude
construction of the Revised Project under the General Plan and Zoning. The Ivy Arcadia
is referred to as the “Revised Project”; and
WHEREAS, on August 18, 2020, the City Council adopted a Mitigated Negative
Declaration (“MND”) for the Approved Project. An Addendum to the adopted MND for The
Ivy Arcadia was prepared to consider the environmental impacts of the Revised Project
compared to those of the approved project, and in accordance with the requirements of
2
California Environmental Quality Act (“CEQA”) and the CEQA Guidelines. As with the
Approved Project, the Revised Project would be required to comply with all the mitigation
measures identified in the adopted 2020 MND. There are no design features included
within the Revised Project that would suggest that these mitigation measures would not
be sufficient to address any potentially significant impact that would arise from the
implementation of the Revised Project. As such, there are no changes to the
circumstances, and implementation of the Revised Project would not result in any new
significant or substantially more severe environmental impacts that would affect the
determination of less-than-significant impact and less-than-significant impact with
mitigation in the adopted 2020 MND; and
WHEREAS, on May 14, 2024, a duly noticed public hearing was held before the
Planning Commission on said Revised Project, at which time all interested persons were
given full opportunity to be heard and to present evidence; and
WHEREAS, following consideration of all testimony and evidence including staff
reports and attachments, the Planning Commission voted unanimously to recommend
denial of the Revised Project on the basis that the Project was not compatible with the
adjacent neighborhood in terms of scale and height and that they could not make three
of the nine required findings. The Planning Commission directed Staff to prepare a
Resolution incorporating the Planning Commission’s findings for the Revised Project; and
WHEREAS, on June 11, 2024, the Revised Project was pulled from the consent
calendar to allow the Applicant to present changes to the design before the Planning
Commission, at which time all interested persons were given full opportunity to be heard
and to present evidence; and
3
WHEREAS, following consideration of all testimony, the Planning Commission
voted 3-0, with two Commissioners absent, to approve Planning Commission Resolution
No. 2146 recommending denial of the Revised Project, which incorporated the Planning
Commission’s findings for the Revised Project; and
WHEREAS, on August 20, 2024, a duly noticed public hearing was held before the
City Council to consider the Revised Project, at which time all interested persons were
given full opportunity to be heard and to present evidence; and
WHEREAS, after taking all testimony and closing the public hearing, the City
Council voted 4-0 to continue its review of the Project to the September 17, 2024, City
Council Meeting to allow the Applicant time to schedule a meeting with the neighboring
property owners and discuss the project; and
WHEREAS, on September 17, 2024, the item was further considered by the City
Council.
NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF ARCADIA,
CALIFORNIA, HEREBY RESOLVES AS FOLLOWS:
SECTION 1. The factual data submitted by the Development Services Department
in the staff report dated September 17, 2024, are true and correct.
SECTION 2. The City Council finds, based upon the entire record, pursuant to
Sections 9107.09.050(B) and 9107.19.050(F) of the Development Code, all of the
following findings can be made.
Conditional Use Permit
1. The Revised Project is consistent with the General Plan and any applicable
specific plan; and is allowed within the applicable zone, subject to the granting of a
4
Conditional Use Permit, and complies with all other applicable provisions of the
Development Code and the Municipal Code.
FACT: Approval of the Revised Project will be consistent with the Commercial
General Plan Land Use Designation. The site is zoned General Commercial (C-G) and
pursuant to the Arcadia Development Code Section 9102.03.020, Table 2-8, allows a
Large-Residential Care Facility in the General Commercial C-G zone subject to the review
and approval of a Conditional Use Permit. The underlying zone allows for a broad array of
commercial uses that are both neighborhood and citywide serving. The Revised Project
will allow a business that can serve the aging population of the City, specifically those with
Alzheimer’s disease and related memory delays. Aside from the FAR, the Revised Project
complies will all the development standards of the General Commercial C-G zone. The
Revised Project will not adversely affect the comprehensive General Plan, and is
consistent with the following General Plan goals and policies:
• Goal LU-1: A balance of land uses that preserves Arcadia status as a
Community of Homes and a community of opportunity.
• Policy LU-1.1: Promote new infill and redevelopment projects that are
consistent with the City’s land use and compatible with surrounding existing
uses.
• Policy LU-1.2: Promote new uses of land that provide diverse economic,
social, and cultural opportunities, and that reinforce the characteristics that
make Arcadia a desirable place to live.
5
• Policy LU-1.5: Require that effective buffer areas be created between land
uses that are of significantly different character or that have operating
characteristics which could create nuisances along common boundary.
2. The design, location, size, and operating characteristics of the proposed
activity will be compatible with the existing and future land uses in the vicinity.
FACT: The Revised Project provides a transition between the commercial
businesses in the Los Angeles County area to the west of the site and the adjacent
residential properties to the east and south as a senior assisted living use. The Revised
Project will be setback more than the minimum required from the adjacent residential
properties and will have a parking and landscape buffer between the facility and the
residential uses. The Revised Project, being more of a residential use, is not expected to
negatively affect the adjacent properties. Parking for the project is above the minimum
required and is expected to be an adequate amount for the site due to the nature of the
use which would not consist of many residents that drive. Additionally, transportation
services will be provided to the residents. Additionally, the Revised Project will result in an
overall reduction of vehicular traffic as compared to the existing use and most other
commercial uses that could be considered for the property. The project site is adequate in
size and location to accommodate the revised development. Thus, the Revised Project
will be compatible with the existing and future uses in the vicinity.
3. The site is physically suitable in terms of:
a. Its design, location, shape, size, and operating characteristics of the proposed
use in order to accommodate the use, and all fences, landscaping, loading, parking,
6
spaces, walls, yards, and other features required to adjust the use with the land and uses
in the neighborhood.
FACT: The site measures approximately 2.82 acres and is large enough to
physically support the Revised Project. The current utility infrastructure on site is more
than capable of accommodating the proposed use. Landscaping is being maintained along
the perimeter of the lot and various new pockets of landscaping will be introduced around
the building site. The Revised Project will have two points of access on to the lot and will
also provide more than the required amount of parking. The Revised Project will comply
with all of the regulations within the Development Code except for the FAR which is
allowed to exceed the maximum because of the density bonus for senior housing
development. Therefore, the site is adequate in size to accommodate the Revised Project.
b. Streets and highways adequate in width and pavement type to accommodate
public and emergency vehicle (e.g., fire and medical) access;
FACT: The Revised Project will be located at the southeast corner of W. Colorado
Boulevard and Michillinda Avenue. The site will have two access points, with one driveway
off of each street frontage. Both streets have been designated and designed with the
capacity to accommodate both normal public vehicular travel and emergency vehicles.
Additionally, the Revised Project is expected to generate less traffic than the previous use.
Thus, the adjacent streets are adequate in width and pavement type to carry the traffic
that would be generated by the Revised Project and to accommodate emergency vehicle
access.
c. Public protection services (e.g., fire protection, police protection, etc.); and
7
FACT: The construction of the senior assisted living care facility will comply with
the Building and Fire Codes, and all other applicable regulations to ensure the safety of
the residents and facilitate emergency services. As part of the environmental review
process, the Addendum to the Initial Study/Mitigated Negative Declaration determined that
Fire and Police protection services can handle the demand for the Revised Project.
d. The provision of utilities (e.g., potable water, schools, solid waste collection and
disposal, storm drainage, wastewater collection, treatment, and disposal, etc.).
FACT: It has been determined that the existing infrastructure and public utilities can
handle the demand for the Project, and no upgrades are required. The Project will also
comply with the Low Impact Development (“LID”) requirements for stormwater discharge
through the implementation of a modular wetland on site.
4. The measure of site suitability shall be required to ensure that the type,
density, and intensity of use being proposed will not adversely affect the public
convenience, health, interest, safety, or general welfare, constitute a nuisance, or be
materially injurious to the improvements, persons, property, or uses in the vicinity and zone
in which the property is located.
FACT: The Revised Project is not expected to be detrimental to the public health or
welfare, or the surrounding residential and commercial properties. The Revised Project
has been designed to be functionally suitable for the site and be sensitive to the privacy
and impact on the adjacent residential properties. The Revised Project includes setbacks
that exceed the minimum requirement and a landscape and parking buffer. In support of
maintaining privacy between the neighboring residential properties, the existing large trees
along the perimeter of the site will be kept. Additionally, most of the units on the upper
8
floors of the south side of the facility do not face the adjacent residential properties.
Therefore, the Revised Project has incorporated design elements to provide added privacy
to the neighbors. The Revised Project is expected to generate less trips than the previous
restaurant use on the site and will have more than the minimum required parking. Traffic
in the surrounding area is not expected to be impacted by the use. The construction of the
project will meet all Building and Fire Codes, and all other applicable regulations.
Therefore, the Revised Project will not adversely affect the public in general nor will it
impact the uses in the vicinity and zone in which the property is located.
Architectural Design Review
5. The proposed development is in compliance with all applicable development
standards and regulation in the Development Code.
FACT: The Revised Project is in compliance with all of the applicable development
standards for the C-G zone, such as the maximum height, setbacks, and parking. The
Revised Project proposes a Floor Area Ratio (“FAR”) of 0.88. The Revised Project is a
senior housing development under the State’s Density Bonus Law and is entitled to
exceed the otherwise maximum FAR, which would physically preclude construction of the
Revised Project to the maximum allow residential density under the General Plan and
Zoning. Therefore, the Revised Project meets the intent of this finding.
6. The proposed development is consistent in the objectives and standards of
the applicable Design Guidelines.
FACT: The Project is designed in the Traditional/Cape Cod architectural style. The
design contains architectural features and materials that are commonly found within the
revised architectural styles. The revised design provides varied massing and materials
9
and articulation on each of the building façades to help break up the building size which is
encouraged by the Design Guidelines. The Revised Project also takes into account the
privacy and site layout guidelines to ensure that there are minimal impacts on the
surrounding properties. Therefore, the Revised Project has been designed to be
consistent with the Design Guidelines.
7. The proposed development is compatible in terms of scale and aesthetic
design with surrounding properties and developments.
FACT: The building was strategically placed away from residential properties to the
east and south to minimize any potential impacts to the adjacent residential properties and
was pushed back from the street to maintain a comparable streetscape with the residential
properties. The overall design has a balanced and aesthetically pleasing design that will
complement the surrounding residential properties in the general vicinity. The use,
although commercial in nature, will provide more of a residential type of use and will be
less commercially active than other potential developments that could be developed on
this site. The revised design will enhance the overall streetscape, as it provides a transition
from the commercial corridor to the west of the site to the residential neighborhoods to the
east. The location of the Project on the southeastern corner of W. Colorado Boulevard and
Michillinda Avenue also provides a suitable focal point as an entryway to the City.
8. The proposed development will have an adequate and efficient site layout in
terms of access, vehicular circulation, parking, and landscaping.
FACT: The site, being a corner lot, will have two points of access, with one driveway
from W. Colorado Boulevard and another driveway from Michillinda Avenue. The two
access points will assist in providing ease of circulation on the lot along with the drive
10
aisles on site which meet the minimum 25’-0” width required for two-way traffic. Parking
will be provided along all four sides of the building and a total of 70 parking spaces are
being provided despite the code only requiring 38 spaces. Additionally, the lot will retain
much of the existing landscaping along the perimeters of the property in supplying
screening to the adjacent residential neighbors, which consist of large trees and hedging,
and new pockets of landscaping will be introduced around the building to enhance the
architectural design of the building.
9. The proposed development will be in compliance with all of the applicable
criteria identified in Section 9107.19.040(C.5).
FACT: All City requirements regarding disabled access and facilities, occupancy
limits, building safety, health code compliance, emergency equipment, environmental
regulation compliance, and parking and site design shall be complied with by the property
owner/applicant to the satisfaction of the Building Official, City Engineer, Deputy
Development Services Director, Fire Marshal, and Public Works Services Director, or their
respective designees. Additionally, the Revised Project will be in compliance with the
General Plan, Development Code, Density Bonus law for senior housing developments,
the City’s Design Guidelines, and all other applicable City regulations.
SECTION 3. For the foregoing reasons, the City Council adopts the Addendum
to the Mitigated Negative Declaration in accordance with CEQA and determines the
findings can be made to approve, and does hereby approve, Architectural Design Review
No. ADR 23-13 with a density bonus and Conditional Use Permit No. CUP 23-09, for a
new senior assisted living care facility at 1150 W. Colorado Boulevard, subject to the
conditions of approval attached hereto.

39. To the maximum extent permitted by law, Applicant must defend, indemnify, and
hold the City, any departments, agencies, divisions, boards, and/or commissions of
the City, and its elected officials, officers, contractors serving as City officials, agents,
employees, and attorneys of the City (“Indemnitees”) harmless from liability for
damages and/or claims, actions, or proceedings for damages for personal injuries,
including death, and claims for property damage, and with respect to all other actions
and liabilities for damages caused or alleged to have been caused by reason of the
Applicant’s activities in connection with ADR 23-13 with a density bonus and CUP
23-09 (“Revised Project”) on the Project site, and which may arise from the direct or
indirect operations of the Applicant or those of the Applicant’s contractors, agents,
tenants, employees or any other persons acting on Applicant’s behalf, which relate
to the development and/or construction of the Project. This indemnity provision
applies to all damages and claims, actions, or proceedings for damages, as
described above, regardless of whether the City prepared, supplied, or approved the
plans, specifications, or other documents for the Project.
In the event of any legal action challenging the validity, applicability, or interpretation
of any provision of this approval, or any other supporting document relating to the
Project, the City will notify the Applicant of the claim, action, or proceedings and will
cooperate in the defense of the matter. The Applicant must indemnify, defend and
hold harmless the Indemnitees, and each of them, with respect to all liability, costs
and expenses incurred by, and/or awarded against, the City or any of the
Indemnitees in relation to such action. Within 15 days’ notice from the City of any
such action, the Applicant shall provide to the City a cash deposit to cover legal fees,
costs, and expenses incurred by City in connection with defense of any legal action
in an initial amount to be reasonably determined by the City Attorney. The City may
draw funds from the deposit for such fees, costs, and expenses. Within 5 business
18
days of each and every notice from the City that the deposit has fallen below the
initial amount, Applicant/Property Owner shall replenish the deposit each and every
time in order for City’s legal team to continue working on the matter. The City shall
only refund to the Applicant/Property Owner any unexpended funds from the deposit
within 30 days of: (i) a final, non-appealable decision by a court of competent
jurisdiction resolving the legal action; or (ii) full and complete settlement of legal
action. The City shall have the right to select legal counsel of its choice. The parties
hereby agree to cooperate in defending such action. The City will not voluntarily
assist in any such third-party challenge(s). In consideration for approval of the
Project, this condition shall remain in effect if the entitlement(s) related to this Project
is rescinded or revoked, at the request of the Applicant or not.
40. Approval of Architectural Design Review No. ADR 23-13 with a density bonus and
Conditional Use Permit No. CUP 23-09 shall not be in effect unless the Property
Owner and Applicant have executed and filed the Acceptance Form with the City on
or before 30 calendar days after the Planning Commission has adopted the
Resolution. The Acceptance Form to the Development Services Department is to
indicate awareness and acceptance of the conditions of approval.
Mitigation Measures as Conditions of Approval
The following conditions are found in the Mitigation Monitoring and Reporting Program
(MMRP). They are recorded here to facilitate review and implementation. More
information on the timing and responsible parties for these mitigation measures are
detailed in the MMRP.
Biological Resources
41. BIO-1: Tree removal shall not occur during the local nesting season (February 1 to
September 15 for nesting birds and February 1 to June 30 for nesting raptors), to
the extent practicable. If any construction or tree removal occurs during the nesting
season, a nesting bird survey shall be conducted by a qualified biologist prior to
commencement of grading or removal of any trees on the property. If the biologist
determines that nesting birds are present, restrictions may be placed on construction
activities in the vicinity of the nest observed until the nest is no longer active, as
determined by the biologist based on the location of the nest, type of the construction
activities, the existing human activity in the vicinity of the nest, and the sensitivity of
the nesting species. Grading and/or construction may resume in this area when a
qualified biologist has determined that the nest is no longer occupied, and all
juveniles have fledged. This measure shall be implemented to the satisfaction of the
Deputy Development Services Director or Designee.
42. BIO-2: Prior to issuance of a building permit, the applicant shall demonstrate that the
Project landscaping plan and planned construction are consistent with the City’s Tree
Protection Ordinance and the Protected Tree Study. The tree protection activities shall
include the following:
19
a. Prior to demolition, the contractor and consulting arborist shall meet on-site to
make sure tree protection zones are established around all protected trees to
be preserved and to review the goals for the tree protection plan.
b. Tree protection zone fences shall be placed around each protected tree.
Fences shall be at least 4 feet tall and constructed of chain-link fencing
secured on metal posts. Where fences are not feasible (e.g., in haul routes or
areas where workers will need frequent access), soil and root protection
material can be installed.
c. The contractor shall maintain the fences and/or soil protection material
throughout the completion of the Project. No staging of materials or equipment
or washing out shall occur within the fenced protected zones.
d. Trees should be irrigated throughout the year. A deep watering that provides
good soil moisture to a depth of 16 inches is optimal. The trees shall be deeply
water once every 21 to 28 days during the summer and fall seasons when
rain is unlikely.
e. For Tree No. 49, a protected deodar cedar located on the Project Site’s
Colorado Boulevard frontage, the deadwood shall be removed to prevent the
dead branches from falling. However, no reduction pruning in the live crown
of the tree is required. The tree shall be monitored for its health during the life
of the Project, and irrigation shall occur at the same frequency of the other
trees.
f. The arborist shall monitor a few critical phases of the Project, including pre-
demolition, to direct the installation of protective fences and soil protection
measures; grading and excavation; any utility or drainage trenching that is
required within a tree protection zone; and a final evaluation during the
landscape installation phase.
g. Additional construction best practices described in the Protected Tree Report
shall be implemented.
Cultural Resources
43. CUL-1: Treatment of previously unidentified archaeological deposits: If suspected
prehistoric or historical archaeological deposits are discovered during construction,
all work within 25 feet of the discovery shall be redirected and a Secretary of the
Interior Professional Qualified archaeologist and/or Registered Professional
Archaeologist shall assess the situation and make recommendations regarding the
treatment of the discovery. Impacts to significant archaeological deposits shall be
avoided if feasible, but if such impacts cannot be avoided, the deposits shall be
evaluated for their eligibility for the California Register of Historical Resources. If the
deposits are not eligible, no further protection of the find is necessary. If the deposits
are eligible, impacts shall be avoided or mitigated. Acceptable mitigation may consist
of, but is not necessarily limited to, systematic recovery and analysis of
archaeological deposits, recording the resource, preparation of a report of findings,
and accessioning recovered archaeological materials at an appropriate curation
facility.
Geology and Soils
20
44. GEO-1: If paleontological resources (fossils) are discovered during Project grading,
work shall be halted in that area until a qualified paleontologist can be retained to
assess the significance of the find. The Project paleontologist shall monitor
remaining earth-moving activities at the Project Site and shall be equipped to record
and salvage fossil resources that may be unearthed during grading activities. The
paleontologist shall be empowered to temporarily halt or divert grading equipment
to allow recording and removal of the unearthed resources. Any fossils found shall
be evaluated in accordance with the CEQA Guidelines and offered for curation at an
accredited facility approved by the City of Arcadia. Once grading activities have
ceased or the paleontologist determines that monitoring is no longer necessary,
monitoring activities shall be discontinued.
Noise
45. NOI-1: Prior to issuance of a Grading Permit, the Project applicant shall
demonstrate, to the satisfaction of the City of Arcadia Planning Division, that the
Project complies with the following:
a. Construction contracts specify that all construction equipment, fixed or
mobile, shall be equipped with properly operating and maintained mufflers
and other State-required noise attenuation devices.
b. The contractor shall provide evidence that a construction staff member will
be designated as a noise disturbance coordinator and will be present on-
site during construction activities. The noise disturbance coordinator shall
be responsible for responding to any local complaints about construction
noise. When a complaint is received, the noise disturbance coordinator shall
notify the City within 24 hours of the complaint and determine the cause of
the noise complaint (e.g., starting too early or bad muffler) and shall
implement reasonable measures to resolve the complaint, as deemed
acceptable by the Deputy Development Services Director (or designee). All
notices that are sent to residential units immediately surrounding the
construction site and all signs posted at the construction site shall include
the contact name and the telephone number for the noise disturbance
coordinator. All necessary signage and notices shall be posted on or sent
to residential units immediately surrounding the construction site no less
than two weeks prior to the start of noise-generating construction activities
on the Project Site.
c. During construction, stationary construction equipment shall be placed such
that emitted noise is directed away from sensitive noise receivers.
d. Prior to issuance of any Grading or Building Permit, the Project applicant
shall demonstrate to the satisfaction of the Deputy Development Services
Director (or designee) that construction noise reduction methods shall be
used where feasible. These reduction methods may include shutting off
idling equipment, installing temporary acoustic barriers around stationary
construction noise sources, maximizing the distance between construction
equipment staging areas and occupied residential areas, and utilizing
electric air compressors and similar power tools.
21
e. Construction haul routes shall be designed to avoid noise-sensitive uses
(e.g., residences and convalescent homes) to the extent feasible.
Tribal Cultural Resources
46. TCR-1: The Project Applicant shall be required to retain and compensate for the
services of a tribal monitor/consultant, who is both approved by the Gabrieleño Band
of Mission Indians-Kizh Nation Tribal Government and listed under the Native
American Heritage Commission’s (NAHC) Tribal Contact list for the area of the
project location. This list is provided by the NAHC. The monitor/consultant shall only
be present on-site during the construction phases that involve ground disturbing
activities. Ground disturbing activities are defined by the Gabrieleño Band of Mission
Indians-Kizh Nation as activities that may include, but are not limited to, pavement
removal, pot-holing or auguring, grubbing, tree removals, boring, grading,
excavation, drilling, and trenching, within the Project area. The tribal
Monitor/consultant shall complete daily monitoring logs that will provide descriptions
of the day’s activities, including construction activities, locations, soil, and any
cultural materials identified. The on-site monitoring shall end when the Project Site
grading and excavation activities are completed or when the tribal representatives
and monitor/consultant have indicated that the site has a low potential for impacting
tribal cultural resources.
47. TCR-2: Upon discovery of any tribal cultural or archaeological resources,
construction activities shall cease in the immediate vicinity of the find until the find
can be assessed. All tribal cultural and archaeological resources unearthed by
Project construction activities shall be evaluated by the qualified archaeologist and
tribal monitor/consultant approved by the Gabrieleño Band of Mission Indians-Kizh
Nation. If the resources are Native American in origin, the Gabrieleño Band of
Mission Indians-Kizh Nation shall coordinate with the landowner regarding treatment
and curation of these resources. Typically, the tribe will request preservation in place
or recovery for educational purposes. Work may continue on other parts of the
Project Site while evaluation and, if necessary, additional protective mitigation takes
place (CEQA Guidelines Section15064.5 [f]). If a resource is determined by the
qualified archaeologist to constitute a “historical resource” or “unique archaeological
resource,” time allotment and funding sufficient to allow for implementation of
avoidance measures, or appropriate mitigation, must be available. The treatment
plan established for the resources shall be in accordance with CEQA Guidelines
Section 15064.5(f) for historical resources. For unique archaeological resources,
preservation in place is the preferred manner of treatment in accordance with PRC
Section 21083.2(b). If preservation in place is not feasible, treatment may include
implementation of archaeological data recovery excavations to remove the resource
along with subsequent laboratory processing and analysis. All tribal cultural
resources shall be returned to the tribe. Any historic archaeological material that is
not Native American in origin shall be curated at a public, nonprofit institution with a
research interest in the materials, such as the Natural History Museum of Los
Angeles County or the Fowler Museum, if such an institution agrees to accept the
22
material. If no institution accepts the archaeological material, they shall be offered
to the tribe or a local school or historical society in the area for educational purposes.
48. TCR-3: Native American human remains are defined in PRC 5097.98 (d)(1) as an
inhumation or cremation, and in any state of decomposition or skeletal
completeness. Funerary objects, called associated grave goods in PRC 5097.98,
are also to be treated according to this statute. Health and Safety Code 7050.5
dictates that any discoveries of human skeletal material shall be immediately
reported to the County Coroner and excavation halted until the coroner has
determined the nature of the remains. If the coroner recognizes the human remains
to be those of a Native American or has reason to believe that they are those of a
Native American, he or she shall contact, by telephone within 24 hours, the NAHC
and PRC 5097.98 shall be followed.
Upon discovery of human remains, the tribal and/or archaeological monitor/
consultant/consultant shall immediately divert work at minimum of 150 feet and
place an exclusion zone around the discovery location. The monitor/consultant(s)
shall then notify the tribe, the qualified lead archaeologist, and the construction
manager who will call the coroner. Work shall continue to be diverted while the
coroner determines whether the remains are human and subsequently Native
American. The discovery is to be kept confidential and secure to prevent any further
disturbance. If the finds are determined to be Native American, the coroner shall
notify the NAHC as mandated by State law, who will then appoint a Most Likely
Descendent (MLD). If the Gabrieleño Band of Mission Indians – Kizh Nation is
designated MLD, the Koo-nas-gna Burial Policy shall be implemented. To the tribe,
the term “human remains” encompasses more than human bones. In ancient, as
well as, historic times, tribal traditions included, but were not limited to, the
preparation of the soil for burial, the burial of funerary objects with the deceased,
and the ceremonial burning of human remains. The prepared soil and cremation
soils are to be treated in the same manner as bone fragments that remain intact.
Associated funerary objects are objects that, as part of the death rite or ceremony
of a culture, are reasonably believed to have been placed with individual human
remains either at the time of death or later; other items made exclusively for burial
purposes or to contain human remains can also be considered as associated
funerary objects.
Prior to the continuation of ground disturbing activities, the land owner shall arrange
a designated site location within the footprint of the Project for the respectful reburial
of the human remains and/or ceremonial objects. In the case where discovered
human remains cannot be fully documented and recovered on the same day, the
remains shall be covered with muslin cloth and a steel plate that can be moved by
heavy equipment placed over the excavation opening to protect the remains. If this
type of steel plate is not available, a 24-hour guard should be posted outside of
working hours. The tribe shall make every effort to recommend diverting the Project
and keeping the remains in situ and protected. If the Project cannot be diverted, it
may be determined that burials shall be removed. The tribe shall work closely with
the qualified archaeologist to ensure that the excavation is treated carefully, ethically
23
and respectfully. If data recovery are approved by the tribe, documentation shall be
taken which includes at a minimum detailed descriptive notes and sketches.
Additional types of documentation shall be approved by the tribe for data recovery
purposes. Cremations shall either be removed in bulk or by means as necessary to
ensure completely recovery of all material. If the discovery of human remains
includes four or more burials, the location is considered a cemetery and a separate
treatment plan shall be created. Once complete, a final report of all activities is to be
submitted to the tribe and the NAHC. The tribe does not authorize any scientific
study or the utilization of any invasive and/or destructive diagnostics on human
remains. Each occurrence of human remains and associated funerary objects shall
be stored using opaque cloth bags. All human remains, funerary objects, sacred
objects and objects of cultural patrimony shall be removed to a secure container on
site if possible. These items shall be retained and reburied within six months of
recovery. The site of reburial/repatriation shall be on the Project Site but at a location
agreed upon between the tribe and the landowner at a site to be protected in
perpetuity. There shall be no publicity regarding any cultural materials recovered.
49. TCR-4: Archaeological and Native American monitoring and excavation during
construction projects shall be consistent with current professional standards. All
feasible care to avoid any unnecessary disturbance, physical modification, or
separation of human remains and associated funerary objects shall be taken.
Principal personnel must meet the Secretary of Interior’s Standards for archaeology
and have a minimum of 10 years of experience as a principal investigator working
with Native American archaeological sites in Southern California. The qualified
archaeologist shall ensure that all other personnel are appropriately trained and
qualified.

By: Edwin Arreola, Acting Senior Planner
SUBJECT: RESOLUTION NO. 7572 APPROVING ARCHITECTURAL DESIGN
REVIEW NO. ADR 23-13 WITH A DENSITY BONUS AND CONDITIONAL
USE PERMIT NO. CUP 23-09 FOR A REVISED SENIOR ASSISTED
LIVING CARE FACILITY (“THE IVY ARCADIA”) WITH AN ADDENDUM TO
THE ADOPTED MITIGATED NEGATIVE DECLARATION UNDER THE
CALIFORNIA ENVIRONMENTAL QUALITY ACT (“CEQA”) AT 1150 W.
COLORADO BOULEVARD
CEQA: Adopt Addendum to Previously Approved Mitigated Negative
Declaration
Recommendation: Adopt
SUMMARY
The Applicant, O&I Development, LLC, on behalf of the property owner, Artis Senior
Living, LLC, is requesting approval of Architectural Design Review No. ADR 23-13 with a
density bonus and Conditional Use Permit No. CUP 23-09, to amend a project that was
approved by the City Council in 2020 for a new two-story senior assisted living care facility
project with 80 units (Artis Senior Living Project) at 1150 W. Colorado Boulevard. The
revised project, known as “The Ivy Arcadia,” will be a three-story senior assisted living
care facility with 100 units and 114 beds. The revised project includes a density bonus to
allow the Floor Area Ratio (“FAR”) of 0.88, which exceeds the maximum permitted FAR
of 0.50. The Planning Commission voted 3-0, with two Commissioners absent, to
recommend denial of the proposed project to the City Council. The Planning Commission
determined that the project was not compatible with the adjacent neighborhood in terms
of scale and height.
It is recommended that the City Council find that the proposal adheres to the required
findings and regulations and adopt Resolution No. 7572 adopting the Addendum to the
Adopted Mitigated Negative Declaration and approving Architectural Design Review No.
ADR 23-13 with a density bonus and Conditional Use Permit No. CUP 23-09 for the
revised project known as the “The Ivy Arcadia.”

BACKGROUND
The subject site is located at the southeast corner of W. Colorado Boulevard and
Michillinda Avenue at 1150 W. Colorado Boulevard. It is zoned General Commercial (C-
G) and has a General Plan Land Use Designation of Commercial (.50 FAR). The site is
approximately 2.82 acres in size and is currently developed with a vacant 13,088 square
foot building that was previously occupied by Coco’s Bakery and Restaurant, which
closed in July 2021. The site is surrounded by the 210 Freeway to the north, commercial
uses to the west in unincorporated Los Angeles County, and single-family residential
properties to the east and south. The residential properties adjacent to this site along the
west side of N. Altura Road and both the north and south side of Altura Terrance are not
within the Lower Rancho Homeowners Association (“HOA”) but the homes beyond those
are located within the Lower Rancho HOA - refer to Figure 1 for an aerial view of the area,
and Attachment No. 2 for an Aerial Photo with Zoning Information.
Figure 1 – Aerial View of the Site
On August 18, 2020, the City Council adopted a Mitigated Negative Declaration and
approved the Artis Senior Living Project. The Artis Senior Living Project involved the
demolition of the former Coco’s building and the development of a new two-story 44,192
square foot senior living care facility with 80 senior housing units and on-site amenities,
inclusive of a community center, a gallery, a café, a barber/beauty shop, a small health
N

center for the residents, and 58 parking spaces and one loading space for deliveries. The
approval also included a Zone Change for the removal of the Architectural Design Overlay
Zone and the Automobile Parking Overlay Zone from the site, which restricted the height
and buildable area on the lot.
The City granted the Applicant two one-year extensions, primarily as a result of the
COVID-19 pandemic and the impacts on the industry, but the entitlements expired on
March 18, 2024. On November 9, 2023, the Applicant for The Ivy Arcadia filed a revised
assisted living care facility project proposal with the City.
DISCUSSION
The revised project consists of demolishing the existing 13,088 square foot restaurant
building and constructing a new 107,706 square foot, three-story Traditional/Cape Cod
architectural style building that will provide assisted living and memory care services for
seniors that have Alzheimer’s and other related memory loss – refer to Attachment No. 3
for the Architectural Plans and Renderings. The Development Code allows a Large-
Residential Care Facility in the General Commercial (C-G) Zone subject to the approval
of a Conditional Use Permit.
The Applicant, O&I Development, LLC, together with Oakmont Management Group,
based in Irvine, California, operate 90 facilities in California, Hawaii, and Nevada that
serve over 8,000 seniors. This will be Oakmont’s first facility in Arcadia, known as “The
Ivy Arcadia”. This facility will provide 24-hour staffing and will provide residents with
services such as daily meals, housekeeping services, transportation services, social
activities, and other support services. The facility will serve persons 60 years of age or
older; however, the average resident age for assisted living is 86 years old. The facility
will have up to 20 employees working between the hours of 10:00 p.m. to 2:00 p.m. and
25 employees between the hours of 2:00 p.m. to 10:00 p.m.
The Planning Commission held a public hearing on May 14, 2024, to forward a
recommendation to the City Council on the proposed project. During the public hearing,
five residents from the adjacent properties spoke against the project citing concerns with
privacy due to the height and scale of the project as well as noise impacts. After
discussion, the Planning Commission voted unanimously to recommend denial to the City
Council and have staff return with a revised Resolution at its June 11 meeting – refer to
Attachment No. 5 for an Excerpt of the May 14, 2024, Planning Commission Minutes and
the Planning Commission Staff Report.
At the June 11, 2024, Planning Commission meeting, the item was pulled from the
consent calendar for further discussion. The Applicant was given additional time to
present changes to the original project that was brought forth to the Planning Commission
after hearing the neighboring property owners’ concerns with privacy, noise, and project
aesthetics at the May 14, 2024, Planning Commission hearing. The Applicant conducted
outreach to the neighboring property owners and held a meeting with the neighbors on
June 3, 2024, to provide redesign updates and address any additional concerns. While
1150 W. Colorado Boulevard – The Ivy Arcadia
August 20, 2024
Page 4 of 16
the square footage, number of units, and number of beds will remain the same, the
Applicant has made revisions that further address some of the neighbors’ concerns, as
later discussed in this analysis. The Applicant also provided view simulations of the
project from the neighboring residential properties. A total of four residents spoke in
opposition to the revised changes. The residents still had concerns with privacy due to
the height and scale of the project. After discussion, the Planning Commission voted to
adopt Resolution No. 2146 recommending denial to the City Council.
The facility will have 100 units with a total of 114 beds. The units will consist of varying
room types, including studio, one-bedroom, and two-bedroom units for assisted living and
private and shared studios for memory care. The units will range between 396 square
foot studios to 1,146 square foot two-bedroom units – refer to Figure 2 below for a Unit
Summary. Unit amenities will include kitchens in some of the units, bathrooms, and closet
space. The first floor will be comprised of 14 units for assisted living, 30 units for memory
care, lobbies, offices, a dining room and a café, a laundry room, a sensory wellness room,
a reading room, and a sitting and music area, as well as separate open-air courtyards in
the middle of the building. The second floor will be comprised of 36 units for assisted
living, offices, a laundry room, and a staff lounge. The third floor will include 20 units for
assisted living, a dining room with an exhibition kitchen, a bar/lounge, an activity room, a
media room, a fitness center with a physical therapy area, a beauty salon, and storage
areas. Additionally, the facility will have an exterior outdoor patio for memory care
patients, a workout area, a trash enclosure, and an emergency generator room. A dog
park and a bocce ball court will be located on the southeastern portion of the property.
1150 W. Colorado Boulevard – The Ivy Arcadia
August 20, 2024

Figure 2 – Unit Summary
After the neighbors adjacent to the easterly property line brought up concerns with the
proximity of these amenities at the Planning Commission hearing, the Applicant reduced
the size of the dog park area from 1,380 square feet to approximately 685 square feet
and both the bocce ball court and dog park have been set back approximately 22’-5”
instead of the originally proposed 10’-0” from the neighboring properties to the east to
accommodate additional landscape screening. The project design is intended to
accommodate the needs of assisted living residents in addition to memory care residents,
which requires space for additional quality of life amenities and services for the two
1150 W. Colorado Boulevard – The Ivy Arcadia
August 20, 2024
Page 6 of 16
resident populations. As with the previously approved project, this proposal will provide
housing options to the aging population in the region, and assistance for those with
memory care needs. The redevelopment of the site with a senior assisted living care
facility was determined by the City Council and Planning Commission back in 2020 as an
appropriate use and development for this property that will not negatively affect the
adjacent residential properties.
The proposed height and setbacks for the revised project have been summarized in
Figure 3 below. As can be seen, the proposed setbacks significantly exceed the setbacks
required in the zone.
Proposed Required
Height 40’-0” 40’-0” Maximum
Front Setback 20’-0” None
Street Side Setback 50’-0” 5’-0” Minimum
Interior Side Setback 51’-9” 10’-0” Minimum
Rear Setback 35’-0” 20’-0” Minimum
Figure 3 – Proposed Height and Setbacks
Most of the units on the second and third floors do not face the adjacent residential
properties. On the south side of the building, a total of three (3) units on the second floor
and three (3) units on the third floor face the adjacent residential properties. On the east
side of the building, a total of nine (9) units on the second floor and four (4) units on the
third floor face the adjacent residential properties to the east. Furthermore, the additional
setback and landscape screening, which was added after hearing the neighbors’
concerns at the Planning Commission hearing, provide additional privacy to the
neighboring property owners along the property line. Therefore, the project has
incorporated design elements to provide added privacy to the neighbors. The senior
assisted living care facility has been designed to be functionally suitable for the proposed
site and greater setbacks were provided to be sensitive to the neighbors in terms of
privacy.
The underlying General Commercial (C-G) Zone allows a maximum FAR of 0.5. The
proposed senior assisted living care facility has a FAR of 0.88, which exceeds the
maximum permitted FAR. However, under the California Density Bonus Law, a project is
entitled to receive a density bonus as a matter of right if it meets the requirements of
California Government Code Section 65915. In addition, pursuant to Senate Bill (SB) 713
that was signed by the Governor in October 2023, a local government cannot apply any
development standard that precludes the construction of a development seeking a density
bonus. Since the project is a senior housing development, it is entitled to receive a density
1150 W. Colorado Boulevard – The Ivy Arcadia
August 20, 2024
Page 7 of 16
bonus and deviate from the maximum permitted FAR, which would otherwise physically
preclude the construction of the proposal based on the maximum allowable residential
density under the C-G Zone. The density bonus law does not require affordability for
senior housing projects. By virtue of it being a senior housing project, it is subject to the
density bonus law requirements. Aside from the FAR, the project would comply with all
applicable development standards of the General Commercial C-G Zone, including height
and setbacks.
Similar to the approved project, the proposed building is designed in a Traditional/Cape
Cod architectural style with varied massing and materials and articulation on each of the
building façades to help break up the building size – refer to Figure 4 below for renderings
of the project. The location on the southeastern corner of W. Colorado Boulevard and
Michillinda Avenue provides a suitable focal point as an entryway to the City. The
proposed design is consistent with the community character, and will enhance the overall
streetscape, as it provides a transition from the commercial corridor to the west of the
site, to the residential neighborhoods to the east. The design contains architectural
features commonly found within the Traditional and Cape Cod architectural styles, such
as white and gray colored vertical and horizontal cement fiber board siding, gray colored
shingle siding, gray asphalt shingle roofing, and stone veneer at the base of the building.
The design also includes many decorative features, such as white colored Juliet balconies
and navy colored wooden shutters on most of the windows, accent gray standing seam
metal roofing, planter boxes along the sides of the building, and a porte cochere and front
porch that act as focal points on the street side elevations of the building. The use of the
various materials along with the articulation provided on each of the building façades
helps prevent long or tall looking wall expanses that would otherwise make the building
appear large.
The overall design is well balanced and aesthetically pleasing with the use of neutral tone
colors. Although commercial buildings are typically encouraged to be placed closer to the
street, the large setback provided to this building helps it fit in more as a part of the
residential neighborhood, in proximity. This revised design will elevate this corner as one
of the gateways into the City.
1150 W. Colorado Boulevard – The Ivy Arcadia
August 20, 2024

Figure 4 – Rendering View from W. Colorado Boulevard (top) and Michillinda Avenue (bottom)
Vehicular access to the site will be provided off the two existing driveways, one along
Colorado Boulevard near the northeastern corner of the property and another along
Michillinda Avenue near the southwestern corner. These driveways are proposed to be
reconstructed in the same general location in compliance with the Americans with
Disabilities Act (“ADA”). A porte cochere will also be provided in front of the main entrance
to the facility as a loading and unloading area for the residents.
The Development Code requires one (1) parking space for every three (3) licensed beds
within the residential care facility. With a total of 114 beds proposed, the project requires
a total of 38 parking spaces for the residents, employees, and visitors. Although the Code
does not require additional parking for the employees, the Applicant is proposing 22 more
parking spaces than the minimum required to ensure there is more than sufficient parking
at any given time. The Applicant has reduced the number of parking spaces from 70
spaces to 60 spaces to address the neighbors’ concerns with potential noise from the
vehicles along the shared property lines. Four (4) spaces were removed from alongside
the eastern property line and six (6) spaces were removed from alongside the southern
property line. The site will provide 49 standard spaces, 3 handicap parking spaces, 7
electric vehicle (“EV”) spaces, and 1 EV space that complies with ADA requirements.
Parking will be located along the perimeter of the site and EV spaces, after the
neighboring residents expressed concerns about the location of spaces along the eastern
property line, have been relocated away from the property line and along the eastern side
of the proposed building - refer to Figure 5 for the Site Plan. The number of parking spaces
proposed is expected to be more than adequate for the site due to the nature of the use,
with most residents not having a vehicle. Additionally, according to the traffic analysis,
this senior assisted living care facility is expected to generate less trips than the previous
Coco’s restaurant operation.

Figure 5 – Site Plan
There are 72 existing trees on site. Of those trees, 22 unprotected ones will be removed.
A total of 16 trees on site are protected trees and will be preserved. The Applicant has
revised the proposed landscaping to provide denser screening of the proposed building
from the residential properties to the east and south, as privacy was a major concern with
the adjacent residents. Per the revised conceptual landscape plan, screening shrubs are
proposed to be planted as an additional layer along portions of the trees that currently
exist along the property line. Additional trees are proposed to be planted in areas where
trees are not present adjacent to the property line. An approximately 20-foot-wide
landscape screening area runs along most of the easterly property line consisting of three
layers: the existing trees adjacent to the property line; a proposed row of screening
shrubs; and a row of Brisbane box and crape myrtle trees. In total, 83 new trees are
proposed to be planted on site and on the public parkway as part of the conceptual
landscape plan. The Applicant will be required to comply with all the tree protection
measures in the Arborist Report to ensure that the protected trees will not be harmed
1150 W. Colorado Boulevard – The Ivy Arcadia
August 20, 2024
Page 10 of 16
during any construction activities – refer to condition of approval no. 4 and Attachment
No. 4.
The previously approved project required a Protected Tree Encroachment Permit for the
encroachment into the driplines of four off-site protected trees. However, the
Development Code was amended in 2021 to not require an encroachment permit for any
trees off-site that are not protected Oak or Sycamore trees. Since these four protected
trees are not oaks or sycamores, a Protected Tree Encroachment Permit is no longer
required.
Originally, a retaining wall was being proposed along portions of the eastern and southern
property line. Residents expressed safety and aesthetic concerns with the location of that
wall. Thus, the Applicant has reworked the grading on site and relocated the retaining
wall further into the subject lot, eliminating the need for the retaining wall to be adjacent
to the property line.
As part of the new development, a 4-foot-wide dedication along W. Colorado Boulevard
and Michillinda Avenue will be granted to the City to accommodate the widening of the
public rights-of-way from approximately 8 feet to 12 feet in width. Construction of the
project is expected to occur over a 20-month period.
FINDINGS
The following findings must be made to approve the proposed project. The sections below
contemplate the required findings in totality of the proposal, including the modifications
made in response to adjacent property owner concerns.
Conditional Use Permit
Section 9107.09.050(B) of the Development Code requires that for a Conditional Use
Permit to be granted, it must be found that all of the following prerequisite findings can be
satisfied:
1. The proposed use is consistent with the General Plan and any applicable
specific plan; and is allowed within the applicable zone, subject to the granting
of a Conditional Use Permit, and complies with all other applicable provisions
of the Development Code and the Municipal Code.
Facts to Support This Finding: Approval of the senior assisted living care facility will
be consistent with the Commercial General Plan Land Use Designation. The site is
zoned General Commercial (C-G) and, pursuant to the Arcadia Development Code
Section 9102.03.020, Table 2-8 allows a Large-Residential Care Facility in the
General Commercial C-G Zone subject to the review and approval of a Conditional
Use Permit. The underlying zone allows for a broad array of commercial uses that are
both neighborhood and Citywide serving. The senior assisted living care facility will
allow a business that can serve the aging population of the City, specifically those with
1150 W. Colorado Boulevard – The Ivy Arcadia
August 20, 2024
Page 11 of 16
Alzheimer’s disease and related memory delays. Aside from the FAR, which is a
concession of the density bonus, the project complies will all the development
standards of the General Commercial C-G Zone. The proposed project will not
adversely affect the comprehensive General Plan, and is consistent with the following
General Plan goals and policies:
• Goal LU-1: A balance of land uses that preserves Arcadia status as a Community
of Homes and a community of opportunity.
• Policy LU-1.1: Promote new infill and redevelopment projects that are consistent
with the City’s land use and compatible with surrounding existing uses.
• Policy LU-1.2: Promote new uses of land that provide diverse economic, social,
and cultural opportunities, and that reinforce the characteristics that make Arcadia
a desirable place to live.
• Policy LU-1.5: Require that effective buffer areas be created between land uses
that are of significantly different character or that have operating characteristics
which could create nuisances along common boundary.
2. The design, location, size, and operating characteristics of the proposed activity
will be compatible with the existing and future land uses in the vicinity.
Facts to Support This Finding: The project provides a transition between the
commercial businesses in the Los Angeles County area to the west of the site and the
adjacent residential properties to the east and south as a senior assisted living use.
The proposed building will be set back more than the minimum required from the
adjacent residential properties and will have a parking and landscape buffer between
the facility and the residential uses. The proposed use, being more of a residential
use, is not expected to negatively affect the adjacent properties. Parking for the project
is above the minimum required and is expected to be an adequate amount for the site
due to the nature of the use. Additionally, transportation services will be provided to
the residents, and the project will result in an overall reduction of vehicular traffic as
compared to the existing use and most other commercial uses that could be
considered for the property. The project site is adequate in size and location to
accommodate the revised development. Thus, the proposed senior assisted living
care facility will be compatible with the existing and future uses in the vicinity.
3. The site is physically suitable in terms of:
a. Its design, location, shape, size, and operating characteristics of the
proposed use in order to accommodate the use, and all fences, landscaping,
loading, parking, spaces, walls, yards, and other features required to adjust
the use with the land and uses in the neighborhood.
Facts to Support This Finding: The site measures approximately 2.82 acres and
is large enough to physically support the new senior care facility. The current utility
infrastructure on site is more than capable of accommodating the proposed use.
1150 W. Colorado Boulevard – The Ivy Arcadia
August 20, 2024
Page 12 of 16
Landscaping is being maintained along the perimeter of the lot and various new
pockets of landscaping will be introduced around the building site. The project will
have two points of access on to the lot and will also provide more than the required
amount of parking. The proposed project will comply with all of the regulations
within the Development Code except for the FAR, which is allowed to exceed the
maximum because of the density bonus for senior housing development.
Therefore, the site is adequate in size to accommodate the proposed senior
assisted living care facility.
b. Streets and highways adequate in width and pavement type to accommodate
public and emergency vehicle (e.g., fire and medical) access.
Facts to Support This Finding: The project will be located at the southeast corner
of W. Colorado Boulevard and Michillinda Avenue. The site will have two access
points, with one driveway off each street frontage. Both streets have been
designated and designed with the capacity to accommodate both normal public
vehicular travel and emergency vehicles. Additionally, the project is expected to
generate less traffic than the previous use. Thus, the adjacent streets are adequate
in width and pavement type to carry the traffic that would be generated by the
proposed facility and to accommodate emergency vehicle access.
c. Public protection services (e.g., fire protection, police protection, etc.).
Facts to Support This Finding: The construction of the senior assisted living
care facility will comply with the Building and Fire Codes, and all other applicable
regulations to ensure the safety of the residents and facilitate emergency services.
As part of the environmental review process, the Addendum to the Initial
Study/Mitigated Negative Declaration determined that Fire and Police protection
services can handle the demand for the proposed senior assisted living care
facility.
d. The provision of utilities (e.g., potable water, schools, solid waste collection
and disposal, storm drainage, wastewater collection, treatment, and
disposal, etc.).
Facts to Support This Finding: It has been determined that the existing
infrastructure and public utilities can handle the demand for the proposed senior
assisted living care facility, and no upgrades are required. The proposed project
will also comply with the Low Impact Development (“LID”) requirements for
stormwater discharge through the implementation of a modular wetland on site.
4. The measure of site suitability shall be required to ensure that the type, density,
and intensity of use being proposed will not adversely affect the public
convenience, health, interest, safety, or general welfare, constitute a nuisance,
or be materially injurious to the improvements, persons, property, or uses in the
vicinity and zone in which the property is located.
1150 W. Colorado Boulevard – The Ivy Arcadia
August 20, 2024
Page 13 of 16
Facts to Support This Finding: The proposed senior facility is not expected to be
detrimental to the public health or welfare, or the surrounding residential and
commercial properties. The proposed senior assisted living care facility has been
designed to be functionally suitable for the proposed site and be sensitive to the
privacy and impact on the adjacent residential properties. The project includes
setbacks that exceed the minimum requirement and a landscape and parking buffer.
In support of maintaining privacy between the neighboring residential properties, the
existing large trees along the perimeter of the site will be kept. Additionally, most of
the units on the upper floors of the south side and some units on the upper floor of the
east side of the facility do not face the adjacent residential properties. Therefore, the
project has incorporated design elements to provide added privacy to the neighbors.
The proposed senior assisted living care facility is expected to generate less trips than
the previous restaurant use on the site and will have more than the minimum required
parking. Traffic in the surrounding area is not expected to be impacted by the use. The
construction of the project will meet all Building and Fire Codes and all other applicable
regulations. Therefore, the proposed project will not adversely affect the public in
general nor will it impact the uses in the vicinity and zone in which the property is
located.
Architectural Design Review
Section 9107.19.050(F) of the Development Code requires that for an Architectural
Design Review to be granted, it must be found that all the following prerequisite findings
can be satisfied:
1. The proposed development is in compliance with all applicable development
standards and regulation in the Development Code.
Facts to Support This Finding: The proposed senior assisted living care facility is in
compliance with all of the applicable development standards for the C-G Zone, such
as the maximum height, setbacks, and parking. The revised project proposes a Floor
Area Ratio (“FAR”) of 0.88. The revised project is a senior housing development under
the State’s Density Bonus Law and is entitled to exceed the otherwise maximum FAR,
which would physically preclude construction of the revised project to the maximum
allowable residential density under the General Plan and Zoning. Therefore, the
revised project meets the intent of this finding.
2. The proposed development is consistent in the objectives and standards of the
applicable Design Guidelines.
Facts to Support This Finding: The proposed senior assisted living care facility is
designed in the Traditional/Cape Cod architectural style. The design contains
architectural features and materials that are commonly found within the proposed
architectural styles and which are present in the residential neighborhoods near the
site. The proposed design provides varied massing and materials and articulation on
each of the building façades to help break up the building size, which is encouraged

by the Design Guidelines. The development also considers the privacy and site layout
guidelines to ensure that there are minimal impacts on the surrounding properties.
Therefore, the project has been designed to be consistent with the Design Guidelines.
3. The proposed development is compatible in terms of scale and aesthetic design
with surrounding properties and developments.
Facts to Support This Finding: The building was strategically placed away from
residential properties to the east and south to minimize any potential impacts to the
adjacent residential properties and was pushed back from the streets to maintain a
comparable streetscape with the residential properties. The overall design has a
balanced and aesthetically pleasing design that will complement the surrounding
residential properties in the general vicinity. The use, although commercial in nature,
will provide more of a residential type of use and will be less commercially active than
other potential developments that could be developed on this site. The proposed
design will enhance the overall streetscape, as it provides a transition from the
commercial corridor to the west of the site to the residential neighborhoods to the east.
The location of the project on the southeastern corner of W. Colorado Boulevard and
Michillinda Avenue also provides a suitable focal point as an entryway to the City.
4. The proposed development will have an adequate and efficient site layout in
terms of access, vehicular circulation, parking, and landscaping.
Facts to Support This Finding: The site, being a corner lot, will have two points of
access, with one driveway from W. Colorado Boulevard and another driveway from
Michillinda Avenue. The two access points will assist in providing ease of circulation
on the lot along with the drive aisles on site, which meet the minimum 25’-0” width
required for two-way traffic. Parking will be provided along all four sides of the building
and a total of 60 parking spaces are being provided despite the Code only requiring
38 spaces. Additionally, the lot will retain much of the existing mature landscaping
along the perimeters of the property in supplying screening to the adjacent residential
neighbors, which consist of large trees and hedging, and new pockets of landscaping
will be introduced around the building to enhance the architectural design of the
building.
5. The proposed development will be in compliance with all of the applicable
criteria identified in Section 9107.19.040(C.5).
Facts to Support This Finding: All City requirements regarding disabled access and
facilities, occupancy limits, building safety, health code compliance, emergency
equipment, environmental regulation compliance, and parking and site design shall
be complied with by the property owner/applicant to the satisfaction of the Building
Official, City Engineer, Deputy Development Services Director, Fire Marshal, and
Public Works Services Director, or their respective designees. Additionally, the
proposed development will be in compliance with the General Plan, Development
1150 W. Colorado Boulevard – The Ivy Arcadia
August 20, 2024
Page 15 of 16
Code, Density Bonus law for senior housing developments, the City’s Design
Guidelines, and all other applicable City regulations.
Based on the foregoing and the attached documentation, all required findings can be
made.
ENVIRONMENTAL ASSESSMENT
On August 18, 2020, the City Council adopted a Mitigated Negative Declaration (“MND”)
for the Approved Project – The Artis Senior Living Project. An Addendum to the adopted
MND for The Ivy Arcadia was prepared to consider the environmental impacts of the
revised project compared to those of the approved project, in accordance with the
requirements of California Environmental Quality Act (“CEQA”) and the CEQA Guidelines.
As with the originally Approved Project, the Revised Project would be required to comply
with all the mitigation measures identified in the adopted 2020 MND. There are no design
features included within the Revised Project that would suggest that these mitigation
measures would not be sufficient to address any potentially significant impact that would
arise from the implementation of the Revised Project. As such, it has been determined
that the Revised Project would not result in any new significant environmental impacts
from what was previously analyzed in the adopted 2020 MND – Refer to Attachment No.
6. As such, an Addendum to the MND can be adopted.
PUBLIC NOTICE/COMMENTS
A public hearing notice for this item was posted at the City Clerk’s Office, City Council
Chambers, the Arcadia Library, the City’s website, in the Arcadia Weekly and mailed to
the property owners located within 300 feet of the subject property on May 2, 2024, prior
to the Planning Commission meeting. During the notification period, one concern from the
property owner at 545 N. Altura Road was received regarding damage to their rear wall
because of the mature trees that lie on the project site. Under the conditions of approval
for the project, the Applicant will be required to replace the property line wall along the
entire perimeter if they can obtain owner approval. After the May 14 Planning Commission
Meeting, a total of four letters of opposition were received from the adjacent residents
and two letters of support were received from housing organizations – refer to Attachment
No. 7 for all the public comments.
It should also be noted that the Applicant also presented the project to the Lower Rancho
Homeowners Association Architectural Review Board (“ARB”) on March 21, 2024. The
ARB was pleased with Oakmont’s team and their expertise in senior living management,
and they were satisfied with the building’s design and its height.
Subsequent to the Planning Commission hearing and the revisions to the project based
on input received, a second notice was mailed and published in the same manner as the
original notice on August 8, 2024, specifically for the City Council Meeting. As of August
16, 2024, staff has not received any additional concerns or comments from the public.

BACKGROUND
The subject site is located at the southeast corner of W. Colorado Boulevard and
Michillinda Avenue at 1150 W. Colorado Boulevard. It is zoned General Commercial (C-
G) and has a General Plan Land Use Designation of Commercial (.50 FAR). The site is
approximately 2.82 acres and is currently developed with a vacant 13,088 square foot
building that was previously occupied Coco’s Bakery and Restaurant that closed in July
2021. The site is surrounded by the 210 freeway to the north, commercial uses to the
west in the Los Angeles County area, and single-family residential properties to the east
and south. The residential properties adjacent to this site along the west side of N. Altura
Road and both the north and south side of Altura Terrance are not within the Lower
Rancho Homeowners Association (HOA) but the homes beyond those are located within
the Lower Rancho HOA - refer to Figure No.1 for an aerial view of the area, and
Attachment No. 2 for an Aerial Photo with Zoning Information.
Figure 1 – Aerial View of the Site
On August 18, 2020, the City Council adopted a Mitigated Negative Declaration and
approved the Artis Senior Living Project. The Artis Senior Living Project involved the
demolition of the building and the development of a new two-story 44,192 square foot
senior living care facility with 80 senior housing units and on-site amenities, inclusive of
a community center, a gallery, a café, a barber/beauty shop, a small health center for the
residents, and 58 parking spaces and one loading space for deliveries. The approval also

included a Zone Change for the removal of the Architectural Design Overlay Zone and
the Automobile Parking Overlay Zone from the site which restricted the height and
buildable area on the lot.
The City granted the Applicant two one-year extensions and the entitlements expired on
March 18, 2024. On November 9, 2023, the Applicant for The Ivy Arcadia filed a revised
project of the assisted living care facility with the City.
PROPOSAL
The revised project consists of demolishing the existing 13,088 square foot restaurant
building and construct a new 107,706 square foot, three-story Traditional/Cape Cod
architectural style building that will provide assisted living and memory care services for
seniors that have Alzheimer’s and other related memory loss – refer to Attachment No. 3
for the Architectural Plans and Renderings, and Figure No. 2 below for a rendering of the
project.
The Applicant, O&I Development, LLC - Oakmont Senior Living operates 90 facilities in
California, Hawaii, and Nevada. This will be Oakmont’s first facility in Arcadia, known as
The Ivy Arcadia, and they will provide 24-hour staffing and services such as daily meals,
housekeeping services, transportation services, social activities, and other support
services. The facility will serve persons 60 years of age or older, however, their average
residence age for assisted living is 86 years old. They will have approximately 10
employees between the hours of 10:00 p.m. to 2:00 p.m. and 15 employees between the
hours of 2:00 p.m. to 10:00 p.m.
The facility will have 100 units with 114 beds. The units would consist of varying types,
including studio, one-bedroom, and two-bedroom units for assisted living and private and
shared studios for memory care. The building is proposed to be built at the maximum
height of 40’-0” and will have an interior side yard setback of 51’-9”, whereas 10’-0” is
required, a street-side yard setback of 50’-0”, whereas 5’-0” is required, a minimum rear
yard setback of 35’-0”, whereas 20’-0” is required, and a 29’-0” front yard setback,
whereas no setback is required.

Page 4 of 24
The units will range between 396 square foot studios to 1,146 square foot two-bedroom
units (see Figure 3 below for a Unit Summary). Unit amenities will include kitchens in
some of the units, bathrooms, and closet space. The first floor will comprise of 14 units
for assisted living, 30 units for memory care, lobbies, offices, a dining room and a café, a
laundry room, a sensory wellness room, a reading room, and a sitting and music area, as
well as separate open-air courtyards in the middle of the building. The second floor will
comprise of 36 units for assisted living, offices, a laundry room, and a staff lounge. The
third floor will comprise of 20 units for assisted living, a dining room with an exhibition
kitchen, a bar/lounge, an activity room, a media room, a fitness center with a physical
therapy area, a beauty salon, and storage areas. Additionally, the facility will have an
exterior outdoor patio for memory care patients, a workout area, a trash enclosure, and
an emergency generator room. A dog park and a bocce ball court will be located in the
southeastern portion of the property.
Figure 3 – Unit Summary
Vehicular access to the site will be provided off the two existing driveways, one along
Colorado Boulevard near the northeastern corner of the property and another along
Michillinda Avenue near the southwestern corner. These driveways are proposed to be
reconstructed in the same general location for American with Disabilities Act (ADA)
compliance. A porte cochere would also be provided in front of the main entrance to the
facility as a loading and unloading area for the residents. In terms of parking, the site will
provide 70 parking spaces: 61 standard spaces, 2 handicap parking spaces, 6 electric
The Ivy Arcadia
1150 W. Colorado Boulevard

vehicle (EV) spaces, and 1 EV space that complies with ADA requirements. Parking will
be located along the perimeter of the site (refer to the Site Plan below under Figure 4).
Figure 4 – Site Plan
As part of the project, 22 unprotected trees will be removed. All 16 of the protected trees
on site will be preserved, and additional trees will be planted alongside the remaining
unprotected trees to provide screening of the proposed building from the residential
properties to the east and south. The Applicant will be required to comply with all the tree
protection measures in the Arborist Report to ensure that the protected trees will not be
harm during any construction activities – refer to condition of approval no. 4 and
Attachment No. 4.
As part of the new development, a 4-foot-wide dedication along W. Colorado Boulevard
and Michillinda Avenue will be granted to the City to accommodate the widening of the
The Ivy Arcadia
1150 W. Colorado Boulevard

public rights-of-way from approximately 8 feet to 12 feet in width. Construction of the
project is expected to occur over a 20-month period.
ANALYSIS
The Development Code allows a Large-Residential Care Facility in the General
Commercial (C-G) zone subject to the approval of a Conditional Use Permit. The senior
assisted living care facility has been designed to be functionally suitable for the proposed
site and be sensitive to the privacy and impact on the adjacent residential properties. As
with the previously approved project, this proposal will provide housing options to the
aging population of the region, and assistance for those with memory care needs. The
redevelopment of the site with a senior assisted living care facility was determined by the
City Council and Planning Commission back in 2020 as an appropriate use and
development for this property. According to the traffic analysis, this senior assisted living
care facility is expected to generate less trips than the previous Coco’s restaurant when
it was in operation.
The underlying General Commercial (C-G) zone allows a maximum FAR of 0.5. The
proposed senior assisted living care facility has a FAR of 0.88, which exceeds the
maximum permitted FAR. However, under the California Density Bonus Law, a project is
entitled to receive a density bonus as a matter of right if it meets the requirements of
California Government Code Section 65915. In addition, pursuant to Senate Bill (SB) 713,
which was signed by Governor Newsom in October 2023, a local government cannot
apply any development standard that precludes the construction of a development
seeking a density bonus. Since the project is a senior housing development, it is entitled
to receive a density bonus and deviate from the maximum permitted FAR, which would
otherwise physically preclude the construction of the proposal based on the maximum
allowable residential density under the C-G zone. The density bonus law does not require
affordability for senior housing projects. By virtue of it being a senior housing project, it is
a density bonus law project, and any requests for a density bonus has to be approved by
City Council.
The proposed building will be situated 35’-0” from the adjacent residential properties to
the south, and 51’-9” from the residential properties to the east. To maintain the existing
privacy between facility and the neighboring residential properties, the existing large trees
along the perimeter of the site will be kept and new trees and/or hedges will be added
where there is a gap. Additionally, most of the units on the upper floors of the south side
of the facility do not face the adjacent residential properties. Therefore, the project has
incorporated design elements to provide added privacy to the neighbors.
In terms of parking, the Development Code requires one (1) parking space for every three
(3) licensed beds within the residential care facility. With a total of 114 beds proposed,
the project requires a total of 38 parking spaces for the residents, employees, and visitors.
Although the Code does not require additional parking for the employees, the Applicant
is proposing 32 more parking spaces to ensure there is more than sufficient parking at
any given time. The project would comply with all other applicable development
standards, including height, and setbacks.

The previously approved project required a Protected Tree Encroachment Permit for the
encroachment into the driplines of four, off-site, protected trees. However, the
Development Code has since been amended to not require an encroachment permit for
any trees off-site that are not a protected Oak or Sycamore trees. Since these four
protected trees are not oaks or sycamores, a Protected Tree Encroachment Permit is no
longer required.
Architectural Style
Similarly to the approved project, the proposed building is designed in a Traditional/Cape
Cod architectural style with varied massing and materials and articulation on each of the
building façades to help break up the building size. The proposed design complements
the adjoining residential properties and will enhance the overall streetscape, as it provides
a transition from the commercial corridor to the west of the site to the residential
neighborhoods to the east – refer to Attachment No. 3 for the architectural plans and to
the rendering above. The design contains architectural features that are commonly found
within the Traditional and Cape Cod architectural styles, such as white and gray colored
vertical and horizontal cement fiber board siding, gray colored shingle siding, gray asphalt
shingle roofing, and stone veneer at the base of the building. The design also includes
many decorative features, such as white colored Juliet balconies and navy colored
wooden shutters on most of the windows, accent gray standing seam metal roofing,
planter boxes along the sides of the building, and a porte cochere and front porch that act
as focal points on the street side elevations of the building. The use of the various
materials along with the articulation provided on each of the building façades helps
prevent long or tall looking wall expanses that would otherwise make the building appear
large. The overall design is well balanced and aesthetically pleasing with the use of
neutral tone colors. The location on the southeastern corner of W. Colorado Boulevard
and Michillinda Avenue provides a suitable focal point as an entryway to the City.
Although commercial buildings are typically encouraged to be placed closer to the street,
the large setback provided to this building helps make it fit in as more of a part of the
residential neighborhood in proximity.

This revised design will elevate this corner as the City has also envisioned a high-end
development at this location since this is one of the gateways into the City.
FINDINGS
Conditional Use Permit
Section 9107.09.050(B) of the Development Code requires that for a Conditional Use
Permit to be granted, it must be found that all of the following prerequisite findings can be
satisfied:
1. The proposed use is consistent with the General Plan and any applicable
specific plan; and is allowed within the applicable zone, subject to the granting
of a Conditional Use Permit, and complies with all other applicable provisions
of the Development Code and the Municipal Code.
Facts to Support This Finding: Approval of the senior assisted living care facility will
be consistent with the Commercial General Plan Land Use Designation. The site is
zoned General Commercial (C-G) and pursuant to the Arcadia Development Code
Section 9102.03.020, Table 2-8, allows a Large-Residential Care Facility in the
General Commercial C-G zone subject to the review and approval of a Conditional
Use Permit. The underlying zone allows for a broad array of commercial uses that are
both neighborhood and citywide serving. The senior assisted living care facility will
allow a business that can serve the aging population of the City, specifically those with
Alzheimer’s disease and related memory delays. Aside from the FAR, which is a
concession of the density bonus, the project complies will all the development
standards of the General Commercial C-G zone. The proposed project will not
adversely affect the comprehensive General Plan, and is consistent with the following
General Plan goals and policies:
• Goal LU-1: A balance of land uses that preserves Arcadia status as a Community
of Homes and a community of opportunity.
• Policy LU-1.1: Promote new infill and redevelopment projects that are consistent
with the City’s land use and compatible with surrounding existing uses.
• Policy LU-1.2: Promote new uses of land that provide diverse economic, social,
and cultural opportunities, and that reinforce the characteristics that make Arcadia
a desirable place to live.
• Policy LU-1.5: Require that effective buffer areas be created between land uses
that are of significantly different character or that have operating characteristics
which could create nuisances along common boundary.
2. The design, location, size, and operating characteristics of the proposed activity
will be compatible with the existing and future land uses in the vicinity.
Facts to Support This Finding: The project provides a transition between the
commercial businesses in the Los Angeles County area to the west of the site and the
The Ivy Arcadia
1150 W. Colorado Boulevard
May 14, 2024
Page 9 of 24
adjacent residential properties to the east and south as a senior assisted living use.
The proposed building will be setback more than the minimum required from the
adjacent residential properties and will have a parking and landscape buffer between
the facility and the residential uses. The proposed use, being more of a residential
use, is not expected to negatively affect the adjacent properties. Parking for the project
is above the minimum required and is expected to be an adequate amount for the site
due to the nature of the use which wouldn’t consist of many residents that drive.
Additionally, transportation services will be provided to the residents. Additionally, the
project will result in an overall reduction of vehicular traffic as compared to the existing
use and most other commercial uses that could be considered for the property. The
project site is adequate in size and location to accommodate the revised development.
Thus, the proposed senior assisted living care facility will be compatible with the
existing and future uses in the vicinity.
3. The site is physically suitable in terms of:
a. Its design, location, shape, size, and operating characteristics of the
proposed use in order to accommodate the use, and all fences, landscaping,
loading, parking, spaces, walls, yards, and other features required to adjust
the use with the land and uses in the neighborhood.
Facts to Support This Finding: The site measures approximately 2.82 acres and
is large enough to physically support the new senior care facility. The current utility
infrastructure on site is more than capable of accommodating the proposed use.
Landscaping is being maintained along the perimeter of the lot and various new
pockets of landscaping will be introduced around the building site. The project will
have two points of access on to the lot and will also provide more than the required
amount of parking. The proposed project will comply with all of the regulations
within the Development Code except for the FAR which is allowed to exceed the
maximum because of the density bonus for senior housing development.
Therefore, the site is adequate in size to accommodate the proposed senior
assisted living care facility.
b. Streets and highways adequate in width and pavement type to accommodate
public and emergency vehicle (e.g., fire and medical) access.
Facts to Support This Finding: The project will be located at the southeast corner
of W. Colorado Boulevard and Michillinda Avenue. The site will have two access
points, with one driveway off of each street frontage. Both streets have been
designated and designed with the capacity to accommodate both normal public
vehicular travel and emergency vehicles. Additionally, the project is expected to
generate less traffic than the previous use. Thus, the adjacent streets are adequate
in width and pavement type to carry the traffic that would be generated by the
proposed facility and to accommodate emergency vehicle access.

Page 10 of 24
c. Public protection services (e.g., fire protection, police protection, etc.).
Facts to Support This Finding: The construction of the senior assisted living
care facility will comply with the Building and Fire Codes, and all other applicable
regulations to ensure the safety of the residents and facilitate emergency services.
As part of the environmental review process, the Addendum to the Initial
Study/Mitigated Negative Declaration determined that Fire and Police protection
services can handle the demand for the proposed senior assisted living care
facility.
d. The provision of utilities (e.g., potable water, schools, solid waste collection
and disposal, storm drainage, wastewater collection, treatment, and
disposal, etc.).
Facts to Support This Finding: It has been determined that the existing
infrastructure and public utilities can handle the demand for the proposed senior
assisted living care facility, and no upgrades are required. The proposed project
will also comply with the Low Impact Development (LID) requirements for
stormwater discharge through the implementation of a modular wetland on site.
4. The measure of site suitability shall be required to ensure that the type, density,
and intensity of use being proposed will not adversely affect the public
convenience, health, interest, safety, or general welfare, constitute a nuisance,
or be materially injurious to the improvements, persons, property, or uses in the
vicinity and zone in which the property is located.
Facts to Support This Finding: The proposed senior facility is not expected to be
detrimental to the public health or welfare, or the surrounding residential and
commercial properties. The proposed senior assisted living care facility has been
designed to be functionally suitable for the proposed site and be sensitive to the
privacy and impact on the adjacent residential properties. The project includes
setbacks that exceed the minimum requirement and a landscape and parking buffer.
In support of maintaining privacy between the neighboring residential properties, the
existing large trees along the perimeter of the site will be kept. Additionally, most of
the units on the upper floors of the south side of the facility do not face the adjacent
residential properties. Therefore, the project has incorporated design elements to
provide added privacy to the neighbors. The proposed senior assisted living care
facility is expected to generate less trips than the previous restaurant use on the site
and will have more than the minimum required parking. Traffic in the surrounding area
is not expected to be impacted by the use. The construction of the project will meet all
Building and Fire Codes, and all other applicable regulations. Therefore, the proposed
project will not adversely affect the public in general nor will it impact the uses in the
vicinity and zone in which the property is located.

Architectural Design Review
Section 9107.19.050(F) of the Development Code requires that for an Architectural
Design Review to be granted, it must be found that all of the following prerequisite findings
can be satisfied:
1. The proposed development is in compliance with all applicable development
standards and regulation in the Development Code.
Facts to Support This Finding: The proposed senior assisted living care facility is in
compliance with all of the applicable development standards for the C-G zone, such
as the maximum height, setbacks, and parking. The revised project proposes a Floor
Area Ratio (FAR) of 0.88. The revised project is a senior housing development under
the State’s Density Bonus Law and is entitled to exceed the otherwise maximum FAR,
which would physically preclude construction of the revised project to the maximum
allow residential density under the General Plan and Zoning. Therefore, the revised
project meets the intent of this finding.
2. The proposed development is consistent in the objectives and standards of the
applicable Design Guidelines.
Facts to Support This Finding: The proposed senior assisted living care facility is
designed in the Traditional/Cape Cod architectural style. The design contains
architectural features and materials that are commonly found within the proposed
architectural styles. The proposed design provides varied massing and materials and
articulation on each of the building façades to help break up the building size which is
encouraged by the Design Guidelines. The development also considers the privacy
and site layout guidelines to ensure that there are minimal impacts on the surrounding
properties. Therefore, the project has been designed to be consistent with the Design
Guidelines.
3. The proposed development is compatible in terms of scale and aesthetic design
with surrounding properties and developments.
Facts to Support This Finding: The building was strategically placed away from
residential properties to the east and south to minimize any potential impacts to the
adjacent residential properties and was pushed back from the streets to maintain a
comparable streetscape with the residential properties. The overall design has a
balanced and aesthetically pleasing design that will complement the surrounding
residential properties in the general vicinity. The use, although commercial in nature,
will provide more of a residential type of use and will be less commercially active than
other potential developments that could be developed on this site. The proposed
design will enhance the overall streetscape, as it provides a transition from the
commercial corridor to the west of the site to the residential neighborhoods to the east.
The location of the project on the southeastern corner of W. Colorado Boulevard and
Michillinda Avenue also provides a suitable focal point as an entryway to the City.
The Ivy Arcadia
1150 W. Colorado Boulevard

Page 12 of 24
4. The proposed development will have an adequate and efficient site layout in
terms of access, vehicular circulation, parking, and landscaping.
Facts to Support This Finding: The site, being a corner lot, will have two points of
access, with one driveway from W. Colorado Boulevard and another driveway from
Michillinda Avenue. The two access points will assist in providing ease of circulation
on the lot along with the drive aisles on site which meet the minimum 25’-0” width
required for two-way traffic. Parking will be provided along all four sides of the building
and a total of 70 parking spaces are being provided despite the code only requiring
38 spaces. Additionally, the lot will retain much of the existing landscaping along the
perimeters of the property in supplying screening to the adjacent residential neighbors,
which consist of large trees and hedging, and new pockets of landscaping will be
introduced around the building to enhance the architectural design of the building.
5. The proposed development will be in compliance with all of the applicable
criteria identified in Section 9107.19.040(C.5).
Facts to Support This Finding: All City requirements regarding disabled access and
facilities, occupancy limits, building safety, health code compliance, emergency
equipment, environmental regulation compliance, and parking and site design shall
be complied with by the property owner/applicant to the satisfaction of the Building
Official, City Engineer, Deputy Development Services Director, Fire Marshal, and
Public Works Services Director, or their respective designees. Additionally, the
proposed development will be in compliance with the General Plan, Development
Code, Density Bonus law for senior housing developments, the City’s Design
Guidelines, and all other applicable City regulations.
ENVIRONMENTAL ASSESSMENT
On August 18, 2020, the City Council adopted a Mitigated Negative Declaration (MND)
for the Approved Project – The Artis Senior Living Project. An Addendum to the adopted
MND for The Ivy Arcadia was prepared to consider the environmental impacts of the
revised project compared to those of the approved project, and in accordance with the
requirements of California Environmental Quality Act (CEQA) and the CEQA Guidelines.
As with the Approved Project, the Revised Project would be required to comply with all
the mitigation measures identified in the adopted 2020 MND. There are no design
features included within the Revised Project that would suggest that these mitigation
measures would not be sufficient to address any potentially significant impact that would
arise from the implementation of the Revised Project. As such, there are no changes to
the circumstances, and implementation of the Revised Project would not result in any
new significant or substantially more severe environmental impacts that would affect the
determination of less-than-significant impact and less-than-significant impact with
mitigation in the adopted 2020 MND – Refer to Attachment No. 5.

Mitigation Measures as Conditions of Approval
The Ivy Arcadia
1150 W. Colorado Boulevard
May 14, 2024
Page 19 of 24
The following conditions are found in the Mitigation Monitoring and Reporting Program
(MMRP). They are recorded here to facilitate review and implementation. More
information on the timing and responsible parties for these mitigation measures are
detailed in the MMRP.
Biological Resources
41. BIO-1: Tree removal shall not occur during the local nesting season (February 1 to
September 15 for nesting birds and February 1 to June 30 for nesting raptors), to
the extent practicable. If any construction or tree removal occurs during the nesting
season, a nesting bird survey shall be conducted by a qualified biologist prior to
commencement of grading or removal of any trees on the property. If the biologist
determines that nesting birds are present, restrictions may be placed on construction
activities in the vicinity of the nest observed until the nest is no longer active, as
determined by the biologist based on the location of the nest, type of the construction
activities, the existing human activity in the vicinity of the nest, and the sensitivity of
the nesting species. Grading and/or construction may resume in this area when a
qualified biologist has determined that the nest is no longer occupied, and all
juveniles have fledged. This measure shall be implemented to the satisfaction of the
Deputy Development Services Director or Designee.
42. BIO-2: Prior to issuance of a building permit, the applicant shall demonstrate that the
Project landscaping plan and planned construction are consistent with the City’s Tree
Protection Ordinance and the Protected Tree Study. The tree protection activities shall
include the following:
a. Prior to demolition, the contractor and consulting arborist shall meet on-site to
make sure tree protection zones are established around all protected trees to
be preserved and to review the goals for the tree protection plan.
b. Tree protection zone fences shall be placed around each protected tree.
Fences shall be at least 4 feet tall and constructed of chain-link fencing
secured on metal posts. Where fences are not feasible (e.g., in haul routes or
areas where workers will need frequent access), soil and root protection
material can be installed.
c. The contractor shall maintain the fences and/or soil protection material
throughout the completion of the Project. No staging of materials or equipment
or washing out shall occur within the fenced protected zones.
d. Trees should be irrigated throughout the year. A deep watering that provides
good soil moisture to a depth of 16 inches is optimal. The trees shall be deeply
water once every 21 to 28 days during the summer and fall seasons when
rain is unlikely.
e. For Tree No. 49, a protected deodar cedar located on the Project Site’s
Colorado Boulevard frontage, the deadwood shall be removed to prevent the
dead branches from falling. However, no reduction pruning in the live crown
of the tree is required. The tree shall be monitored for its health during the life
of the Project, and irrigation shall occur at the same frequency of the other
trees.
The Ivy Arcadia
1150 W. Colorado Boulevard
May 14, 2024
Page 20 of 24
f. The arborist shall monitor a few critical phases of the Project, including pre-
demolition, to direct the installation of protective fences and soil protection
measures; grading and excavation; any utility or drainage trenching that is
required within a tree protection zone; and a final evaluation during the
landscape installation phase.
g. Additional construction best practices described in the Protected Tree Report
shall be implemented.
Cultural Resources
43. CUL-1: Treatment of previously unidentified archaeological deposits: If suspected
prehistoric or historical archaeological deposits are discovered during construction,
all work within 25 feet of the discovery shall be redirected and a Secretary of the
Interior Professional Qualified archaeologist and/or Registered Professional
Archaeologist shall assess the situation and make recommendations regarding the
treatment of the discovery. Impacts to significant archaeological deposits shall be
avoided if feasible, but if such impacts cannot be avoided, the deposits shall be
evaluated for their eligibility for the California Register of Historical Resources. If the
deposits are not eligible, no further protection of the find is necessary. If the deposits
are eligible, impacts shall be avoided or mitigated. Acceptable mitigation may consist
of, but is not necessarily limited to, systematic recovery and analysis of
archaeological deposits, recording the resource, preparation of a report of findings,
and accessioning recovered archaeological materials at an appropriate curation
facility.
Geology and Soils
44. GEO-1: If paleontological resources (fossils) are discovered during Project grading,
work shall be halted in that area until a qualified paleontologist can be retained to
assess the significance of the find. The Project paleontologist shall monitor
remaining earth-moving activities at the Project Site and shall be equipped to record
and salvage fossil resources that may be unearthed during grading activities. The
paleontologist shall be empowered to temporarily halt or divert grading equipment
to allow recording and removal of the unearthed resources. Any fossils found shall
be evaluated in accordance with the CEQA Guidelines and offered for curation at an
accredited facility approved by the City of Arcadia. Once grading activities have
ceased or the paleontologist determines that monitoring is no longer necessary,
monitoring activities shall be discontinued.
Noise
45. NOI-1: Prior to issuance of a Grading Permit, the Project applicant shall
demonstrate, to the satisfaction of the City of Arcadia Planning Division, that the
Project complies with the following:
a. Construction contracts specify that all construction equipment, fixed or
mobile, shall be equipped with properly operating and maintained mufflers
and other State-required noise attenuation devices.
The Ivy Arcadia
1150 W. Colorado Boulevard
May 14, 2024
Page 21 of 24
b. The contractor shall provide evidence that a construction staff member will
be designated as a noise disturbance coordinator and will be present on-
site during construction activities. The noise disturbance coordinator shall
be responsible for responding to any local complaints about construction
noise. When a complaint is received, the noise disturbance coordinator shall
notify the City within 24 hours of the complaint and determine the cause of
the noise complaint (e.g., starting too early or bad muffler) and shall
implement reasonable measures to resolve the complaint, as deemed
acceptable by the Deputy Development Services Director (or designee). All
notices that are sent to residential units immediately surrounding the
construction site and all signs posted at the construction site shall include
the contact name and the telephone number for the noise disturbance
coordinator. All necessary signage and notices shall be posted on or sent
to residential units immediately surrounding the construction site no less
than two weeks prior to the start of noise-generating construction activities
on the Project Site.
c. During construction, stationary construction equipment shall be placed such
that emitted noise is directed away from sensitive noise receivers.
d. Prior to issuance of any Grading or Building Permit, the Project applicant
shall demonstrate to the satisfaction of the Deputy Development Services
Director (or designee) that construction noise reduction methods shall be
used where feasible. These reduction methods may include shutting off
idling equipment, installing temporary acoustic barriers around stationary
construction noise sources, maximizing the distance between construction
equipment staging areas and occupied residential areas, and utilizing
electric air compressors and similar power tools.
e. Construction haul routes shall be designed to avoid noise-sensitive uses
(e.g., residences and convalescent homes) to the extent feasible.
Tribal Cultural Resources
46. TCR-1: The Project Applicant shall be required to retain and compensate for the
services of a tribal monitor/consultant, who is both approved by the Gabrieleño Band
of Mission Indians-Kizh Nation Tribal Government and listed under the Native
American Heritage Commission’s (NAHC) Tribal Contact list for the area of the
project location. This list is provided by the NAHC. The monitor/consultant shall only
be present on-site during the construction phases that involve ground disturbing
activities. Ground disturbing activities are defined by the Gabrieleño Band of Mission
Indians-Kizh Nation as activities that may include, but are not limited to, pavement
removal, pot-holing or auguring, grubbing, tree removals, boring, grading,
excavation, drilling, and trenching, within the Project area. The tribal
Monitor/consultant shall complete daily monitoring logs that will provide descriptions
of the day’s activities, including construction activities, locations, soil, and any
cultural materials identified. The on-site monitoring shall end when the Project Site
grading and excavation activities are completed or when the tribal representatives
and monitor/consultant have indicated that the site has a low potential for impacting
tribal cultural resources.
The Ivy Arcadia
1150 W. Colorado Boulevard
May 14, 2024
Page 22 of 24
47. TCR-2: Upon discovery of any tribal cultural or archaeological resources,
construction activities shall cease in the immediate vicinity of the find until the find
can be assessed. All tribal cultural and archaeological resources unearthed by
Project construction activities shall be evaluated by the qualified archaeologist and
tribal monitor/consultant approved by the Gabrieleño Band of Mission Indians-Kizh
Nation. If the resources are Native American in origin, the Gabrieleño Band of
Mission Indians-Kizh Nation shall coordinate with the landowner regarding treatment
and curation of these resources. Typically, the tribe will request preservation in place
or recovery for educational purposes. Work may continue on other parts of the
Project Site while evaluation and, if necessary, additional protective mitigation takes
place (CEQA Guidelines Section15064.5 [f]). If a resource is determined by the
qualified archaeologist to constitute a “historical resource” or “unique archaeological
resource,” time allotment and funding sufficient to allow for implementation of
avoidance measures, or appropriate mitigation, must be available. The treatment
plan established for the resources shall be in accordance with CEQA Guidelines
Section 15064.5(f) for historical resources. For unique archaeological resources,
preservation in place is the preferred manner of treatment in accordance with PRC
Section 21083.2(b). If preservation in place is not feasible, treatment may include
implementation of archaeological data recovery excavations to remove the resource
along with subsequent laboratory processing and analysis. All tribal cultural
resources shall be returned to the tribe. Any historic archaeological material that is
not Native American in origin shall be curated at a public, nonprofit institution with a
research interest in the materials, such as the Natural History Museum of Los
Angeles County or the Fowler Museum, if such an institution agrees to accept the
material. If no institution accepts the archaeological material, they shall be offered
to the tribe or a local school or historical society in the area for educational purposes.
48. TCR-3: Native American human remains are defined in PRC 5097.98 (d)(1) as an
inhumation or cremation, and in any state of decomposition or skeletal
completeness. Funerary objects, called associated grave goods in PRC 5097.98,
are also to be treated according to this statute. Health and Safety Code 7050.5
dictates that any discoveries of human skeletal material shall be immediately
reported to the County Coroner and excavation halted until the coroner has
determined the nature of the remains. If the coroner recognizes the human remains
to be those of a Native American or has reason to believe that they are those of a
Native American, he or she shall contact, by telephone within 24 hours, the NAHC
and PRC 5097.98 shall be followed.
Upon discovery of human remains, the tribal and/or archaeological monitor/
consultant/consultant shall immediately divert work at minimum of 150 feet and
place an exclusion zone around the discovery location. The monitor/consultant(s)
shall then notify the tribe, the qualified lead archaeologist, and the construction
manager who will call the coroner. Work shall continue to be diverted while the
coroner determines whether the remains are human and subsequently Native
American. The discovery is to be kept confidential and secure to prevent any further
disturbance. If the finds are determined to be Native American, the coroner shall
notify the NAHC as mandated by State law, who will then appoint a Most Likely

Page 23 of 24
Descendent (MLD). If the Gabrieleño Band of Mission Indians – Kizh Nation is
designated MLD, the Koo-nas-gna Burial Policy shall be implemented. To the tribe,
the term “human remains” encompasses more than human bones. In ancient, as
well as, historic times, tribal traditions included, but were not limited to, the
preparation of the soil for burial, the burial of funerary objects with the deceased,
and the ceremonial burning of human remains. The prepared soil and cremation
soils are to be treated in the same manner as bone fragments that remain intact.
Associated funerary objects are objects that, as part of the death rite or ceremony
of a culture, are reasonably believed to have been placed with individual human
remains either at the time of death or later; other items made exclusively for burial
purposes or to contain human remains can also be considered as associated
funerary objects.
Prior to the continuation of ground disturbing activities, the land owner shall arrange
a designated site location within the footprint of the Project for the respectful reburial
of the human remains and/or ceremonial objects. In the case where discovered
human remains cannot be fully documented and recovered on the same day, the
remains shall be covered with muslin cloth and a steel plate that can be moved by
heavy equipment placed over the excavation opening to protect the remains. If this
type of steel plate is not available, a 24-hour guard should be posted outside of
working hours. The tribe shall make every effort to recommend diverting the Project
and keeping the remains in situ and protected. If the Project cannot be diverted, it
may be determined that burials shall be removed. The tribe shall work closely with
the qualified archaeologist to ensure that the excavation is treated carefully, ethically
and respectfully. If data recovery are approved by the tribe, documentation shall be
taken which includes at a minimum detailed descriptive notes and sketches.
Additional types of documentation shall be approved by the tribe for data recovery
purposes. Cremations shall either be removed in bulk or by means as necessary to
ensure completely recovery of all material. If the discovery of human remains
includes four or more burials, the location is considered a cemetery and a separate
treatment plan shall be created. Once complete, a final report of all activities is to be
submitted to the tribe and the NAHC. The tribe does not authorize any scientific
study or the utilization of any invasive and/or destructive diagnostics on human
remains. Each occurrence of human remains and associated funerary objects shall
be stored using opaque cloth bags. All human remains, funerary objects, sacred
objects and objects of cultural patrimony shall be removed to a secure container on
site if possible. These items shall be retained and reburied within six months of
recovery. The site of reburial/repatriation shall be on the Project Site but at a location
agreed upon between the tribe and the landowner at a site to be protected in
perpetuity. There shall be no publicity regarding any cultural materials recovered.
49. TCR-4: Archaeological and Native American monitoring and excavation during
construction projects shall be consistent with current professional standards. All
feasible care to avoid any unnecessary disturbance, physical modification, or
separation of human remains and associated funerary objects shall be taken.
Principal personnel must meet the Secretary of Interior’s Standards for archaeology
and have a minimum of 10 years of experience as a principal investigator working
The Ivy Arcadia

with Native American archaeological sites in Southern California. The qualified
archaeologist shall ensure that all other personnel are appropriately trained and
qualified.

City of Arcadia Page 1
1.0 INTRODUCTION
On August 18, 2020, the City of Arcadia City Council adopted a Mitigated Negative Declaration
(2020 MND) for the Artis Senior Living Project, which was proposed at the southeastern corner
of the intersection of Colorado Boulevard and Michillinda Avenue at 1150 West Colorado
Boulevard in the City of Arcadia (see Figure 1). The Artis Senior Living Project involved the
demolition of an approximately 13,000-square-foot building (previously occupied by a Coco’s
Bakery and Restaurant) and the development of a new two-story, 44,192-square-foot
senior/assisted living care facility with 80 senior housing units and on-site amenities, inclusive of
a community center, a gallery, a café, a barber/beauty shop, and a small health center for the
residents, and 58 parking spaces and one loading space (Approved Project).
The Project Applicant, O&I Development, LLC, is now proposing to develop the Project Site with
a new 107,706-square-foot, three-story building containing 100 units (with 114 beds), which
constitutes the Revised Project, known as The Ivy Arcadia. In considering whether to approve the
Revised Project, the City, as the lead agency pursuant to the California Environmental Quality Act
(CEQA), is required to consider the environmental impacts of the Revised Project as compared
to those of the Approved Project. Therefore, this addendum assesses the environmental impacts
of the Revised Project as compared to those of the Approved Project in accordance with the
requirements of CEQA and the CEQA Guidelines.
2.0 STATUTORY BACKGROUND
Under CEQA Guidelines Section 15162(c), once a project has been approved, the lead agency’s
role in project approval is completed unless further discretionary approval on that project is
required. Information appearing after an approval does not require reopening of that approval. If,
after the project is approved, any of the conditions described in CEQA Guidelines Section
15162(a) occurs, a subsequent MND shall only be prepared by the public agency which grants
the next discretionary approval for the project.
More specifically, CEQA Guidelines Section 15162 states the following:
(a) When an EIR has been certified or a negative declaration adopted for a project,
no subsequent EIR shall be prepared for that project unless the lead agency
determines, on the basis of substantial evidence in the light of the whole record,
one or more of the following:
(1) Substantial changes are proposed in the project which will require
major revisions of the previous EIR or negative declaration due to the
involvement of new significant environmental effects or a substantial
increase in the severity of previously identified significant effects;
(2) Substantial changes occur with respect to the circumstances under
which the project is undertaken which will require major revisions of the
previous EIR or Negative Declaration due to the involvement of new
significant environmental effects or a substantial increase in the
severity of previously identified significant effects; or

ADDENDUM
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 3
(3) New information of substantial importance, which was not known and
could not have been known with the exercise of reasonable diligence
at the time the previous EIR was certified as complete or the Negative
Declaration was adopted, shows any of the following:
(A) The project will have one or more significant effects not
discussed in the previous EIR or negative declaration;
(B) Significant effects previously examined will be substantially
more severe than shown in the previous EIR;
(C) Mitigation measures or alternatives previously found not to be
feasible would in fact be feasible, and would substantially
reduce one or more significant effects of the project, but the
project proponents decline to adopt the mitigation measure or
alternative; or
(D) Mitigation measures or alternatives which are considerably
different from those analyzed in the previous EIR would
substantially reduce one or more significant effects on the
environment, but the project proponents decline to adopt the
mitigation measure or alternative.
In addition, CEQA Guidelines Section 15164 states the following:
(a) The lead agency or responsible agency shall prepare an addendum to a
previously certified EIR if some changes or additions are necessary but none
of the conditions described in Section 15162 calling for preparation of a
subsequent EIR have occurred.
(b) An addendum to an adopted negative declaration may be prepared if only
minor technical changes or additions are necessary or none of the conditions
described in Section 15162 calling for the preparation of a subsequent EIR or
negative declaration have occurred.
(c) An addendum need not be circulated for public review but can be included in
or attached to the final EIR or adopted negative declaration.
(d) The decision making body shall consider the addendum with the final EIR or
adopted negative declaration prior to making a decision on the project.
(e) A brief explanation of the decision not to prepare a subsequent EIR pursuant
to Section 15162 should be included in an addendum to an EIR, the lead
agency’s findings on the project, or elsewhere in the record. The explanation
must be supported by substantial evidence.
3.0 SUMMARY OF APPROVED PROJECT DESCRIPTION
Under the Approved Project, the existing, vacant building on-site, which was previously occupied by
Coco’s Bakery and Restaurant, would be demolished, and associated landscaping and surface
parking lot would be removed. However, the majority of the trees along the perimeter of the Project
Site were proposed to be retained and incorporated into the Approved Project’s landscaping plan to
continue to form a vegetative screen between the Project Site and the residential uses to the east and
south. The Approved Project proposed to develop a W-shaped senior living facility, which was
planned to support memory care and assisted living services. This facility was proposed to be entirely
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 4
dedicated to people afflicted with Alzheimer’s disease and related memory disorders. The Approved
Project proposed a new two-story (with a maximum height of 37.5 feet), 44,192-square-foot building
with 80 senior housing units and on-site amenities, inclusive of a community center, a gallery, a café,
a barber/beauty shop, and a small health center for the residents. The Approved Project also
proposed to include decorative landscaping, private walking paths, and an outdoor plaza on the west
and south sides of the Project Site, which were proposed to be enclosed with an 8-foot-high wooden
fence that would connect to the northwestern and northeastern corners of the building and extend to
the southern property line. The Approved Project required a Minor Administrative Modification to allow
the fence to exceed the maximum permitted height of 6 feet.
Under the Approved Project, vehicle parking was proposed to include 55 regular parking stalls and 4
parking stalls that comply with the requirements of the Americans with Disabilities Act (ADA).
Vehicular access to the new building was proposed to be from a single ingress/egress point on
Colorado Boulevard, located at an existing ingress/egress point for the Project Site.
The Approved Project proposed to remove 18 of the 60 unprotected trees on-site, including 13 trees
in the center of the Project Site around the existing building. Although no protected trees were
proposed to be removed or irrevocably damaged during Project-related grading and construction,
some minor damage to the protected tree root systems was anticipated. Accordingly, the Approved
Project required a Tree Encroachment Permit and the implementation of Mitigation Measure BIO-2
to prevent substantial damage to on- and off-site protected trees.
4.0 PROJECT DESCRIPTION
Existing Conditions
The Project Site consists of 2.82 acres of developed land in the northwestern portion of the City
of Arcadia. The Project Site is located on the southeastern corner of the Colorado Boulevard and
Michillinda Avenue intersection, immediately south of Interstate 210 (I-210/Foothill Freeway), as
shown in Figure 1. The Project Site contains a vacant commercial building, previously occupied
by Coco’s Bakery and Restaurant. The existing building, which comprises 13,088 square feet in
total floor area, is a rectangular, one-story building located in the center of the Project Site. The
building is surrounded on all sides by a surface parking lot with two driveway locations, one at the
northeastern corner of the Project Site along Colorado Boulevard and another at the southwestern
corner of the Project Site along Michillinda Avenue. Mature eucalyptus trees flank the western
and eastern sides of the existing building. Additionally, there are decorative shrubs and turf along
the northern, eastern, and western façades of the building, with one mature fern pine near its
northeastern corner. Currently, there is a mix of trees along the perimeter of the Project Site,
serving as a landscape buffer between the Project Site and neighboring streets to the north and
west and between the Project Site and the residential neighborhoods to the east and south.
The Colorado Boulevard and Michillinda Avenue frontages are both improved with a sidewalk,
curb and gutter, two streetlights along each street, two traffic signal poles with safety lights, and
one curb ramp at the southeastern corner. Each frontage is characterized by decorative ground
cover; mature trees; a short, white-painted cinderblock wall; and decorative shrubs located
between the sidewalk and the property line.
The Project Site is designated in the City’s General Plan as Commercial (0.5 FAR) with a
corresponding zoning of General Commercial (C-G).

Revised Project
Under the Revised Project, the Project Applicant is proposing a new 107,706-square-foot, three-
story building (with a maximum height of 40 feet from the average grade of the building) containing
100 units of varying types, including studio, one-bedroom, and two-bedroom units for assisted
living and private and shared studios for memory care, providing a total of 114 beds. As with the
Approved Project, the Revised Project would support assisted living and memory care services,
the latter of which would entirely be dedicated to people afflicted with Alzheimer’s disease and
related memory disorders.
The first floor of the proposed building would comprise 14 units for assisted living and 30 units for
memory care, front and rear lobbies, offices, a dining room and a café, a laundry room, a sensory
wellness room, a reading room, and a sitting and music area, as well as separate open air
courtyards for assisted living and memory care patients in the middle of the building, within 39,472
square feet of floor area. The second floor would comprise 36 units for assisted living, offices, a
laundry room, and a staff lounge within 37,169 square feet of floor area. The third floor would
comprise 20 units for assisted living, a dining room with an exhibition kitchen, a bar/lounge, an
activity room, a media room, a fitness center with a physical therapy area, a beauty salon, and
storage areas within 31,065 square feet of floor area.
In addition, an exterior patio for memory care patients and a workout seating area with outdoor
workout equipment would be located along the southern boundary of the Project Site. A dog park
and a bocce ball court would be located in the southeastern portion of the Project Site, as shown
in Figure 2.
The proposed new building would feature a Cape Cod design with varied massing and materials
with articulation on each of the building façades, similar in design to that of the Approved Project.
Conceptual renderings are shown in Figure 3.
The Revised Project would include multiple new sources of light, including pole-mounted LED
security lighting in parking areas and the passenger drop-off area; path lighting on internal
walkways; and accent lighting over building doorways.
Vehicle parking would include 61 parking spaces, comprising 3 parking spaces that comply with
the requirements of the Americans with Disabilities Act (ADA), 6 electric vehicle (EV) parking
spaces, and 1 EV parking space that complies with ADA requirements. Parking would be located
along the perimeter of the Project Site with one ADA-compliant and one ADA-compliant/EV
parking spaces located near the northeastern corner of the proposed building, two ADA-compliant
parking spaces near the northwestern corner by the main entrance, and six EV parking spaces in
the parking lot along the eastern boundary. Vehicular access to the proposed building would be
from the two existing driveways, one along Colorado Boulevard near the northeastern corner of
the Project Site and another along Michillinda Avenue near the southwestern corner of the Project;
these driveways would be reconstructed in the same general location to current City standards
for ADA compliance. A porte cochere would be provided in front of the main entrance to the
proposed building. A covered trash enclosure would be located along the southern boundary of
the Project Site immediately adjacent to the Alzheimer exterior patio. An emergency generator
would be located in the generator room on the first floor near the southwestern corner of the
proposed building.

In addition, a modular wetland, which is proposed in the southeastern corner of the Project Site,
would be used to collect and treat surface water runoff from the Project Site prior to draining to
the existing curb inlet and then to the existing storm drainage system to the east. With regard to
wastewater, the Revised Project would connect to an existing 21-inch County of Los Angeles
sewer main to the west along Michillinda Avenue via a new sewer lateral.
Regarding on-site trees, although the Revised Project would require the removal of 22
unprotected trees, the Revised Project would not only preserve the majority of trees along the
perimeter of the Project Site, as proposed under the Approved Project, but would plant additional
trees to completely screen the views of the proposed building from the residential uses to the east
and south, as shown in Figure 4. The existing curb, gutter, and sidewalks along the Project Site’s
Colorado Boulevard and Michillinda Avenue frontages would be replaced. In addition, the Revised
Project would be required to dedicate 4 feet of the Project Site along both Colorado Boulevard
and Michillinda Avenue to accommodate the widening of these two public rights-of-way along the
Project Site’s frontages to 12 feet in width; however, the physical improvement would be
implemented by the City and is not part of the Revised Project.
The Project Site’s General Plan land use designation and zoning allow for the development of the
Revised Project through a Conditional Use Permit (CUP) as the Revised Project proposes a floor
area ratio (FAR) of 0.88, which exceeds the maximum permitted FAR of 0.5. Under the California
Density Bonus Law, a project is entitled to receive a density bonus as a matter of right if it meets
the requirements of California Government Code Section 65915. In addition, pursuant to Senate
Bill (SB) 713, which was signed by Governor Newsom in October 2023, a local government cannot
apply any development standard that precludes the construction of a development seeking a
density bonus. Accordingly, pursuant to Government Code Section 65915(b)(1)(C) and SB 713,
as the Revised Project is a senior citizen housing development, the Revised Project is entitled to
receive a density bonus and deviate from the maximum permitted FAR, which would otherwise
physically preclude the construction of the Revised Project based on the maximum allowable
residential density under the General Plan land use and zoning designations. The Revised Project
would comply with all other applicable development standards.
Construction of the Revised Project would occur over a 20-month period, commencing in the fall
of 2024 and concluding in the summer of 2026.
The Revised Project would require the following City approvals:
x Adoption of the Addendum to the IS/MND
x Conditional Use Permit No. CUP 23-09
x Architectural Design Review No. ADR 23-13 with a Density Bonus
x Other discretionary and ministerial permits and approvals that may be deemed necessary,
including, but not limited to grading permit, excavation permit, dedications, and building
permits

5.0 ENVIRONMENTAL ANALYSIS
This section assesses the environmental effects of the Revised Project and compares them to
the environmental effects of the previously Approved Project as disclosed in the adopted 2020
MND to determine if any of the conditions described in CEQA Guidelines Section 15162 calling
for preparation of a subsequent MND have occurred. This section includes the environmental
topics that were included in the 2020 MND.
5.1 AESTHETICS
Scenic Vistas and Scenic Resources
According to the 2020 MND, there are no scenic vistas or scenic highways in the Project vicinity.
Views of the San Gabriel Mountains are only available from main arterial roadways in the City
that are oriented north and south. As such, motorists traveling northbound on Michillinda Avenue
(along the western boundary of the Project Site) and North Altura Road (one block east of the
Project Site) have distant views of the San Gabriel Mountains, which are partially obstructed by
existing mature trees and existing development along both of these streets, I-210, and the
overpass over Michillinda Avenue, as well as utility poles, traffic signals, and business signs on
either side of Michillinda Avenue. As a result of these existing impediments, views of the San
Gabriel Mountains are only available straight north and are obstructed to the northeast and
northwest and would not be significantly affected by the Approved Project. As related to scenic
resources, the existing mature trees along the perimeter of the Project Site, the majority of which
are considered protected by the City, could be considered scenic resources. These protected
trees would be preserved by the Approved Project to continue to provide a visual barrier between
the Project Site and surrounding uses and contribute to maintaining the existing visual character
of the Project area. Accordingly, the 2020 MND determined that the Approved Project would have
a less-than-significant impact on scenic vistas and scenic resources.
The Revised Project proposes the same land use type as the Approved Project within the
boundaries of the Project Site. However, the Revised Project would involve a larger development
and a slightly taller building than analyzed in the 2020 MND. Nonetheless, as with the Approved
Project, views of the San Gabriel Mountains would not be significantly affected by the Revised
Project given the existing intervening features that already obstruct such views and the remaining
north-facing view corridors that would not be affected by the Revised Project. In addition, because
the Revised Project would install additional trees along the eastern and southern boundaries of
the Project Site to completely screen the views between the Project Site and the immediately
adjacent residences, the increase in building height proposed under the Revised Project would
not create an impact beyond those identified in the 2020 MND. Accordingly, as with the Approved
Project, the Revised Project would have a less-than-significant impact on scenic vistas and scenic
resources. Therefore, there are no material changes in circumstances, and the Revised Project
would not result in any new significant or substantially more severe environmental impacts that
would affect the less-than-significant impact determination in the 2020 MND.
Conflict with Zoning Governing Scenic Quality
According to the 2020 MND, the Approved Project would be consistent with underlying City zoning
upon approval of a CUP. Additionally, because the Arcadia Development Code does not contain
any specific zoning regulations that govern scenic quality other than the City’s Tree Preservation
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 11
Ordinance, the impacts discussed focused on the protected trees on the Project Site, which would
be preserved in place to provide visual barriers between the Project Site and surrounding uses
and would maintain the existing visual character of the Project vicinity. Therefore, the Approved
Project would be consistent with applicable zoning and other regulations governing scenic quality,
and impacts were determined to be less than significant.
As with the Approved Project, the Revised Project would preserve the protected trees on the
Project Site and would install additional trees along the eastern and southern boundaries of the
Project Site to completely screen the views between the Project Site and the immediately adjacent
residences and maintain the existing visual character of the Project vicinity. Given the approval
of the Zone Change that eliminated the Architectural Design Overlay Zone and the Automobile
Parking Overlay Zone from the Project Site under the Approved Project, the Revised Project
would not require any additional zone change and, therefore, would be consistent with applicable
zoning regulations, including the height limit of 40 feet for the C-G zoning designation, other
regulations governing scenic quality, and the density bonus law. Thus, impacts would be less than
significant. Therefore, there are no material changes in circumstances, and the Revised Project
would not result in any new significant or substantially more severe environmental impacts that
would affect the less-than-significant impact determination in the 2020 MND.
Light and Glare
According to the 2020 MND, the Approved Project would contain multiple new sources of
nighttime lighting, such as security lighting on internal walkways, lights in the parking areas and
at building entrances, and accent lights along walking paths adjacent to landscaped areas.
However, the Approved Project would be required to demonstrate compliance with Section
9103.01.120(D) of the Arcadia Development Code as part of the City’s design review process,
which limits potential light and glare impacts by requiring that lights be directed downward and
shielded/recessed to avoid spillage to adjacent properties and prohibits flashing or roof-mounted
lights that are directed outward. This Arcadia Development Code section also prohibits light
fixtures that are inappropriate for the scale, intensity, and height of the use they are serving.
Additionally, the Approved Project would not utilize glossy or reflective construction materials that
would generate significant amounts of glare off-site. Accordingly, the 2020 MND determined that
the Approved Project would not generate excessive light or glare and, by complying with lighting
regulations in the Arcadia Development Code, would result in a less-than-significant impact on
day or nighttime views in the Project area.
The Revised Project proposes the same land use type as the Approved Project and would not
include land uses that would require more intense sources of light or building materials that would
create glare beyond those identified for the Approved Project. As with the Approved Project, the
Revised Project would be required to comply with the same regulations that would minimize
impacts related to light and glare. Accordingly, as with the Approved Project, the Revised Project
would not generate excessive light or glare and, by complying with lighting regulations in the
Arcadia Development Code, would result in a less-than-significant impact on day or nighttime
views in the Project area. Therefore, there are no material changes in circumstances, and the
Revised Project would not result in any new significant or substantially more severe environmental
impacts that would affect the less-than-significant impact determination in the 2020 MND.
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 12
5.2 AGRICULTURE AND FORESTRY RESOURCES
According to the 2020 MND, the Project Site and the surrounding area are not mapped as Prime
Farmland, Unique Farmland, and Farmland of Statewide Importance or subject to the Williamson
Act contract. The Project Site is currently developed with an existing vacant building; thus, no
agricultural uses, forestland, or timberland occur on the Project Site or the surrounding areas,
and, as such, none of these uses would be converted to non-agricultural or non-forest uses as a
result of the Approved Project. In addition, the Project Site is zoned as C-G and designated as
Commercial in the City’s General Plan. Accordingly, the Approved Project would not conflict with
existing zoning for, or cause the rezoning of, farmland, forestland, or timberland. Therefore, the
2020 MND determined that development of the Approved Project would have no impact on
agriculture or forestry resources.
As with the Approved Project, the Revised Project would have no impact on agriculture and
forestry resources. Therefore, there are no material changes in circumstances, and the Revised
Project would not result in any new significant or substantially more severe environmental impacts
that would affect the no-impact determination in the 2020 MND.
5.3 AIR QUALITY
Consistency with Plans
According to the 2020 MND, the Approved Project would result in emissions below the regional
and localized emissions thresholds established by the South Coast Air Quality Management
District (SCAQMD) and, as such, would not have the potential to cause or affect a violation of the
ambient air quality standards or delay the timely attainment of air quality standards or 2016 Air
Quality Management Plan (AQMP) emissions reductions goals. In addition, because the
Approved Project is consistent with the underlying zoning and General Plan land use designation
for the Project Site, the population and employment growth associated with the Approved Project
would have been anticipated and planned for in the City’s General Plan, on which the Southern
California Association of Governments (SCAG) bases its growth projections for the City. As the
SCAQMD has incorporated these same projections into the 2016 AQMP, the 2020 MND concluded
that the Approved Project would be consistent with the 2016 AQMP and have a less-than-significant
impact related to consistency with the 2016 AQMP.
Since the adoption of the 2020 MND, the SCAQMD has adopted the 2022 AQMP, the air quality plan
applicable to the Revised Project. The Revised Project would involve a slightly larger development
than analyzed in the 2020 MND. In addition, because the restaurant occupying the existing building
closed after the adoption of the 2020 MND, the trip credit from the restaurant use is no longer applied.
Accordingly, the Revised Project would generate more trips and emissions compared to the Approved
Project. However, as with the Approved Project, construction and operation of the Revised Project
would result in emissions below the regional and localized emissions thresholds established by the
SCAQMD, as shown in Tables 1, 2, and 3, in the discussion of Criteria Pollutants Emissions, below.
As such, the Revised Project would not have the potential to cause or affect a violation of the ambient
air quality standards or delay the timely attainment of air quality standards or 2022 AQMP emissions
reductions goals. In addition, because the Revised Project is also consistent with the underlying
zoning and General Plan land use designation for the Project Site, the Revised Project would also be
consistent with the 2022 AQMP and have a less-than-significant impact related to consistency with
the 2022 AQMP. Therefore, there are no material changes in circumstances, and the Revised Project
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 13
would not result in any new significant or substantially more severe environmental impacts that would
affect the less-than-significant impact determination in the 2020 MND.
Criteria Pollutant Emissions
According to the 2020 MND, construction of the Approved Project, which would take
approximately 20 months to complete, would result in the generation of fugitive dust and pollutant
emissions, resulting in substantial short-term increases in air pollutants. Similarly, operation of the
Approved Project would result in long-term air quality impacts associated with mobile source
emissions from traffic generated by the Approved Project and emissions from stationary area and
energy sources. As mentioned previously, a trip credit was applied from the restaurant use for
operational emissions. However, the 2020 MND determined that that construction and operation
of the Approved Project would not exceed daily regional SCAQMD thresholds for any of the
criteria pollutants analyzed and that impacts would be less than significant.
As with the Approved Project, construction and operation of the Revised Project would result in the
short-term and long-term generation of criteria pollutants, respectively. As described in Section 4.0,
Project Description, of this addendum, construction for the Revised Project would occur
approximately over 20 months. Since the Revised Project would involve a larger development than
analyzed in the 2020 MND and the trip credit from the restaurant use is no longer applied, the
Revised Project would generate more trips and emissions compared to the Approved Project.
However, as with the Approved Project, construction and operation of the Revised Project would
result in emissions below the regional and localized emissions thresholds established by the
SCAQMD, as shown in Tables 1 and 2. As such, the Revised Project would not result in a
cumulatively considerable net increase of any criteria pollutant for which the region is non-
attainment under California Ambient Air Quality Standards (i.e., ozone [O3], respirable particulate
matter [PM10], and fine particulate matter [PM2.5]) and the National Ambient Air Quality Standards
(i.e., O3 and PM2.5). Therefore, there are no material changes in circumstances, and the Revised
Project would not result in any new significant or substantially more severe environmental impacts
that would affect the less-than-significant impact determination in the 2020 MND.

Revised Project Long-Term Operational Emissions
Exposure of Sensitive Receptors to Pollutants
According to the 2020 MND, sensitive receptors in the vicinity of the Project Site include
residential uses adjacent to the east and south, which could be potentially affected by air pollutant
emissions generated during on-site construction activities. However, the 2020 MND determined
that construction emissions resulting from the Approved Project would not exceed the localized
significance thresholds (LSTs) established by the SCAQMD for these existing residences.
According to the SCAQMD LST methodology, LSTs would apply to the operational phase of a
project if the project included stationary sources or attracted mobile sources that may spend
extended periods queuing and idling at the site (e.g., warehouse or transfer facilities). The
Approved Project does not include such uses. Therefore, the 2020 MND determined that impacts
associated with localized emissions from the construction and operation of the Approved Project
would be less than significant.
As with the Approved Project, sensitive receptors to the east and south of the Project Site may
be potentially affected by air pollutant emissions generated during on-site construction activities
of the Revised Project. Although the Revised Project would involve a slightly larger development
than analyzed in the 2020 MND, construction of the Revised Project would not exceed the
localized emissions thresholds for any criteria pollutants, as shown in Table 3. Additionally, the
Revised Project proposes the same land use type as the Approved Project and would not include
uses that may spend extended periods queuing and idling on the Project Site. Similar to the
Approved Project, impacts associated with localized emissions from the construction and

operation of the Revised Project would be less than significant. Therefore, there are no material
changes in circumstances, and the Revised Project would not result in any new significant or
substantially more severe environmental impacts that would affect the less-than-significant impact
determination in the 2020 MND.
Table 3
Revised Project Construction Localized Emissions
Odor and Other Emissions
According to the 2020 MND, the Approved Project would not include any uses identified by the
SCAQMD as being associated with odors. However, construction activities associated with the
Approved Project may generate other emissions and detectable odors from heavy-duty
equipment exhaust and architectural coatings; these construction-related emissions and odors
would be short term in nature and cease upon completion of construction. In addition, the
Approved Project would be required to comply with existing regulations that reduce detectable
odors from architectural coating application and heavy-duty equipment exhaust by limiting
construction equipment idling time. Accordingly, the 2020 MND determined that the Approved
Project would not result in other emissions (such as those leading to odors) adversely affecting a
substantial number of people, and impacts would be less than significant.
The Revised Project proposes the same land use type as the Approved Project and would not
include land uses identified by the SCAQMD as being associated with odors. As with the
Approved Project, construction activities associated with the Revised Project may generate other
emissions and detectable odors from heavy-duty equipment exhaust and architectural coatings.

sensitive receptors (adjacent to the Project Site, as such 25-meter threshold was used), and the source receptor
area (SRA 9).

short term in nature and would cease upon completion of construction. In addition, the Revised
Project would also be required to comply with existing regulations that reduce detectable odors
from architectural coating application and heavy-duty equipment exhaust. As with the Approved
Project, the Revised Project would not result in other emissions (such as those leading to odors)
that would adversely affect a substantial number of people, and impacts would be less than
significant. Therefore, there are no material changes in circumstances, and the Revised Project
would not result in any new significant or substantially more severe environmental impacts that
would affect the less-than-significant impact determination in the 2020 MND.
5.4 BIOLOGICAL RESOURCES
Sensitive Species
According to the 2020 MND, due to the disturbed nature of the Project Site and lack of native
habitat to species known to occur in the City of Arcadia, it was determined that the Project Site
would not support special-status species listed as threatened or endangered by the U.S. Fish and
Wildlife Service (USFWS) or the California Department of Fish and Wildlife (CDFW). In addition,
the Arcadia General Plan does not identify any sensitive or special-status species beyond the
protected trees existing on-site as described below under Local Biological Resources
Policies/Ordinances. Therefore, the 2020 MND determined that the Approved Project would not
have a substantial adverse effect, either directly or through habitat modification, on any species
identified as a candidate, sensitive, or special-status species and that impacts would be less than
significant.
As with the Approved Project, development of the Revised Project would occur within the
boundaries of the Project Site, where no sensitive or special-status species are known to occur.
Accordingly, the Revised Project would not have a substantial adverse effect, either directly or
through habitat modification, on any species identified as a candidate, sensitive, or special-status
species, and impacts would be less than significant. Therefore, there are no material changes in
circumstances, and the Revised Project would not result in any new significant or substantially
more severe environmental impacts that would affect the less-than-significant impact
determination in the 2020 MND.
Riparian Habitat, Wetlands, and Conservation Plans
According to the 2020 MND, the Project Site does not support any riparian habitat, sensitive
communities, or wetlands, and there are no adopted, approved, or proposed habitat conservation
plans, natural community conservation plans, or other approved local, regional, or State
conservation plans that cover habitats located in the City. Therefore, the 2020 MND determined
that development of the Approved Project would have no impact on riparian habitat, sensitive
communities, or wetlands or related to such conservation plans.
As with the Approved Project, development of the Revised Project would occur within the
boundaries of the Project Site, where no riparian habitat, sensitive communities, or wetlands or
applicable conservation plans have been identified. Accordingly, the Revised Project would have
no impact on any riparian habitat, other sensitive natural communities, or wetlands or related to
such conservation plans. Therefore, there are no material changes in circumstances, and the
Revised Project would not result in any new significant or substantially more severe environmental
impacts that would affect the no-impact determination in the 2020 MND.
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 17
Migratory Wildlife
According to the 2020 MND, since the Project Site has been highly disturbed and is surrounded
by developed, urban land uses, the Approved Project would not interfere substantially with the
movement of any native resident or migratory fish or wildlife species. However, 72 trees,
comprising 12 protected and 60 unprotected trees, were identified on-site, which could provide
habitat to animals capable of flight. According to the 2020 MND, the existing building, on-site
trees, and ornamental landscaping could provide suitable roosting and nesting habitat for bird
species. Of the suitable habitat identified, the Approved Project would remove 18 unprotected
trees, the existing building, and other existing landscaping. As such, the 2020 MND determined
that, while migratory bird species are considered highly mobile, the possible removal of suitable
roosting and nesting habitat would result in the potential for minor impacts to bird species. To
reduce this impact to a less-than-significant level, the 2020 MND identified the following mitigation
measure:
BIO-1 Tree removal shall not occur during the local nesting season (February 1 to
September 15 for nesting birds and February 1 to June 30 for nesting raptors), to
the extent practicable. If any construction or tree removal occurs during the nesting
season, a nesting bird survey shall be conducted by a qualified biologist prior to
commencement of grading or removal of any trees on the property. If the biologist
determines that nesting birds are present, restrictions may be placed on construction
activities in the vicinity of the nest observed until the nest is no longer active, as
determined by the biologist based on the location of the nest, type of the construction
activities, the existing human activity in the vicinity of the nest, and the sensitivity of
the nesting species. Grading and/or construction may resume in this area when a
qualified biologist has determined that the nest is no longer occupied, and all
juveniles have fledged. This measure shall be implemented to the satisfaction of the
City of the Planning & Community Development Administrator or Designee.
Development of the Revised Project would require the removal of the existing building, 22
unprotected trees, and ornamental landscaping. Although the Revised Project would remove four
additional trees when compared to the Approved Project, with implementation of Mitigation
Measure BIO-1 required for the Approved Project, development of the Revised Project would not
result in impacts to migratory bird species beyond those identified for the Approved Project.
Therefore, there are no material changes in circumstances, and the Revised Project would not
result in any new significant or substantially more severe environmental impacts to migratory
wildlife that would affect the determination of less-than-significant impact with mitigation in the
2020 MND.
Local Biological Resources Policies/Ordinances
According to the 2020 MND, there were 72 trees located on the Project Site, 12 of which were
considered protected under the City’s Tree Preservation Ordinance with all but two considered to
be in good health. Four additional protected trees were identified off-site but with canopies that
encroach onto the Project Site. The Approved Project would not remove any of these protected
trees but would remove 18 unprotected trees to accommodate the proposed development. Of the
16 protected trees that are on or adjacent to the Project Site, the 12 on-site trees would experience
some light grading within their immediate area. While the Protected Tree Report prepared for the
Approved Project determined that the proposed development would not adversely affect the long-
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 18
term viability of the protected trees on or adjacent to the Project Site, some minor damage to the
protected tree root systems was anticipated during construction. To prevent substantial damage
to on- and off-site protected trees, meet the requirements of the Tree Preservation Ordinance,
and ensure that impact to protected trees would be reduced to a less-than-significant level, the
2020 MND identified the following mitigation measure:
BIO-2 Prior to issuance of a building permit, the applicant shall demonstrate that the Project
landscaping plan and planned construction are consistent with the City’s Tree Protection
Ordinance and the Protected Tree Study. The tree protection activities shall include the
following:
1. Prior to demolition, the contractor and consulting arborist shall meet on-site to make
sure tree protection zones are established around all protected trees to be preserved
and to review the goals for the tree protection plan.
2. Tree protection zone fences shall be placed around each protected tree. Fences
shall be at least 4 feet tall and constructed of chain-link fencing secured on metal
posts. Where fences are not feasible (e.g., in haul routes or areas where workers
will need frequent access), soil and root protection material can be installed.
3. The contractor shall maintain the fences and/or soil protection material throughout
the completion of the Project. No staging of materials or equipment or washing out
shall occur within the fenced protected zones.
4. Trees should be irrigated throughout the year. A deep watering that provides good
soil moisture to a depth of 16 inches is optimal. The trees shall be deeply water once
every 21 to 28 days during the summer and fall seasons when rain is unlikely.
5. For Tree No. 49, a protected deodar cedar located on the Project Site’s Colorado
Boulevard frontage, the deadwood shall be removed to prevent the dead branches
from falling. However, no reduction pruning in the live crown of the tree is required.
The tree shall be monitored for its health during the life of the Project, and irrigation
shall occur at the same frequency of the other trees.
6. The arborist shall monitor a few critical phases of the Project, including pre-
demolition, to direct the installation of protective fences and soil protection
measures; grading and excavation; any utility or drainage trenching that is required
within a tree protection zone; and a final evaluation during the landscape installation
phase.
7. Additional construction best practices described in the Protected Tree Report shall
be implemented.
The tree report that was prepared for the 2020 MND was updated in April 2024 to reflect the
Revised Project. As with the previous tree report, the April 2024 tree report also identified 72 trees
on the Project Site, 12 of which are considered protected under the City’s Tree Preservation
Ordinance with all but three (one more tree than previously identified) considered to be in good
health. As with the previous tree report, four additional protected trees are identified off-site but
with canopies that encroach onto the Project Site. Development of the Revised Project would
require the removal of four additional trees, for a total of 22 unprotected trees, and light grading within
the immediate area of the protected trees, which may result in minor damage to the root systems.
However, as with the Approved Project, the Revised Project would comply with the Tree Preservation
Ordinance and would implement the previously proposed mitigation measure to reduce impacts to
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 19
protected trees. With implementation of Mitigation Measure BIO-2 required for the Approved Project,
development of the Revised Project would not result in impacts to protected trees beyond those
identified for the Approved Project.1 Therefore, there are no material changes in circumstances, and
the Revised Project would not result in any new significant or substantially more severe environmental
impacts that would affect the determination of less-than-significant impact with mitigation in the 2020
MND.
5.5 CULTURAL RESOURCES
Historical Resources
According to the 2020 MND, no historical resources were identified on the Project Site as the
existing building on-site does not meet the age requirement for eligibility listing in in the California
Register of Historical Resources (CRHR). Similarly, there are no cultural resources listed or
eligible for listing in the CRHR within the immediate vicinity of the Project Site. Therefore, the
2020 MND determined that, because physical alterations associated with development of the
Approved Project would not extend beyond the Project Site, the Approved Project would not
cause a substantial adverse change in the significance of a historical resource pursuant to CEQA
Guidelines Section 15064.5, and no impact to historical resources would occur.
As with the Approved Project, development of the Revised Project would occur within the
boundaries of the Project Site, where no historical resources or immediately adjacent resources
have been identified. Accordingly, the Revised Project would have no impact on historical
resources. Therefore, there are no material changes in circumstances, and the Revised Project
would not result in any new significant or substantially more severe environmental impacts that
would affect the no-impact determination in the 2020 MND.
Archaeological Resources
According to the 2020 MND, no archaeological resources were identified on the Project Site or
within a quarter mile of the Project Site; further, the site sensitivity for subsurface archaeological
resources was considered low because the Project Site has been developed and redeveloped.
However, the 2020 MND determined that the potential exists for unanticipated discovery of
archaeological resources during ground-disturbing activities for the Approved Project. To reduce
the impact of the Approved Project on archaeological resources to a less-than-significant level,
the 2020 MND identified the following mitigation measure:
CUL-1 Treatment of previously unidentified archaeological deposits. If suspected
prehistoric or historical archaeological deposits are discovered during construction, all
work within 25 feet of the discovery shall be redirected and a Secretary of the Interior
Professional Qualified archaeologist and/or Registered Professional Archaeologist
shall assess the situation and make recommendations regarding the treatment of the
discovery. Impacts to significant archaeological deposits shall be avoided if feasible,
but if such impacts cannot be avoided, the deposits shall be evaluated for their
eligibility for the California Register of Historical Resources. If the deposits are not
eligible, no further protection of the find is necessary. If the deposits are eligible,
impacts shall be avoided or mitigated. Acceptable mitigation may consist of, but is not

City of Arcadia Page 20
necessarily limited to, systematic recovery and analysis of archaeological deposits,
recording the resource, preparation of a report of findings, and accessioning recovered
archaeological materials at an appropriate curation facility.
As with the Approved Project, development of the Revised Project would result in ground-
disturbing activities during construction and, as such, would result in potential impacts related to
unanticipated discovery of archaeological resources. With implementation of Mitigation Measure
CUL-1 required for the Approved Project, development of the Revised Project would not result in
impacts to archaeological resources beyond those identified for the Approved Project. Therefore,
there are no material changes in circumstances, and the Revised Project would not result in any
new significant or substantially more severe environmental impacts that would affect the
determination of less-than-significant impact with mitigation in the 2020 MND.
Human Remains
According to the 2020 MND, the Approved Project would not likely disturb any human remains,
including those interred outside of dedicated cemeteries given that the Cultural Resources
Identification Memorandum prepared for the Approved Project found no indication of any past
human burial activities on or near the Project Site. However, the 2020 MND determined that the
potential exists to uncover buried human remains during construction-related earth-moving
activities. Nonetheless, the Approved Project would be required to comply with the requirements
of California Health and Safety Code Section 7050.5 related to the proper protocol to which the
Approved Project must adhere in the event that buried human remains are discovered.
Accordingly, the 2020 MND determined that, through compliance with California Health and
Safety Code Section 7050.5, impacts of the Approved Project related to the disturbance of human
remains would be less than significant.
As with the Approved Project, development of the Revised Project would include construction-
related earth-moving activities and, as such, would result in potential impacts related to
unanticipated uncovering of buried human remains. Through compliance with California Health
and Safety Code Section 7050.5, development of the Revised Project would not result in impacts
to human remains beyond those identified for the Approved Project. Therefore, there are no
material changes in circumstances, and the Revised Project would not result in any new
significant or substantially more severe environmental impacts that would affect the less-than-
significant impact determination in the 2020 MND.
5.6 ENERGY
Consumption of Energy Resources
According to the 2020 MND, the Approved Project’s net energy consumption (i.e., minus the energy
consumption of the Coco’s Bakery and Restaurant that was in operation at the time) would
constitute an approximate 0.0004-percent reduction from Los Angeles County’s typical annual
electricity consumption and an approximate 0.0007-percent reduction from Los Angeles County’s
typical annual natural gas consumption as a result of the Approved Project’s compliance with Title
24 standards, which provide efficiency standards related to various building features, including
appliances, water and space heating and cooling equipment, building insulation and roofing, and
lighting. Implementation of Title 24 standards significantly reduces energy usage. In addition, the
Approved Project would generate a net decrease of approximately 374 daily trips when compared
to the previous use on-site (i.e., Coco’s Restaurant). As a result, the Approved Project’s operational
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 21
vehicle consumption would constitute an approximately 0.0002-percent reduction from Los Angeles
County’s fuel consumption. With regard to construction, the Approved Project’s construction fuel
consumption would increase Los Angeles County’s consumption by 0.0069 percent. However, the
2020 MND determined that since the construction and operation of the Approved Project would not
have any unusual characteristics that would result in excessive consumption of electricity, natural
gas, and transportation fuel, the Approved Project would not result in wasteful, inefficient, or
unnecessary consumption of energy resources in comparison to other similar developments in the
region, and impacts related to energy resources would be less than significant.
Since the adoption of the 2020 MND, the restaurant occupying the existing building has closed,
and the building has remained vacant. As such, the trip credit from the restaurant use is no longer
applicable to the Revised Project. In addition, the Revised Project would also involve a slightly
larger development than analyzed in the 2020 MND. Accordingly, the Revised Project would result
in higher energy consumption than the Approved Project. As shown in Table 4, the Revised
Project’s energy usage would constitute an approximate 0.0006-percent increase over Los Angeles
County’s typical annual electricity consumption, an approximate 0.0004 percent increase over Los
Angeles County’s typical annual natural gas consumption, and an approximate 0.4351-percent
increase over Los Angeles County’s fuel consumption. The Revised Project’s construction off-road
and construction on-road fuel consumption would increase the County’s consumption by 0.1307
percent and 0.2683 percent, respectively. These increases would be considered nominal compared
to the County’s annual energy consumption.

As with the Approved Project, because the Revised Project would not have any unusual
characteristics that would result in excessive operational energy consumption associated with
electricity and natural gas usage and vehicular travel, the Revised Project would not result in
wasteful, inefficient, or unnecessary consumption of energy resources in comparison to other
similar developments in the region, and impacts related to energy resources would be less than
significant. Therefore, there are no material changes in circumstances, and the Revised Project
would not result in any new significant or substantially more severe environmental impacts that
would affect the less-than-significant impact determination in the 2020 MND.
Consistency with Plans
According to the 2020 MND, the Approved Project’s overall energy efficiency measures, such as
the use of energy-efficient appliances, heaters, and heating, ventilation, and air conditioning (HVAC)
systems; use of water-efficient landscaping (which would reduce the electricity used for water
transport and treatment); and incorporation of building code-mandated energy-efficient design
features, would generally support the energy reduction goals established in the City’s 2019 Energy
Action Plan. The Approved Project’s energy consumption would be typical of senior living
development projects in Southern California and would not result in an increased energy demand
beyond the capacity of Southern California Edison (SCE) or Southern California Gas Company
(SoCalGas). Accordingly, the 2020 MND determined that the Approved Project would not conflict
with or obstruct any plans for renewable energy or energy efficiency, and no impact would occur.
The Revised Project would involve a slightly larger development than analyzed in the 2020 MND.
However, as with the Approved Project, the Revised Project would use energy-efficient appliances,
heaters, HVAC systems, and water-efficient landscaping (which would reduce the electricity used
for water transport and treatment) and incorporate building code-mandated energy efficient design
features that would generally support the energy reduction goals established in the City’s 2019
Energy Action Plan. As with the Approved Project, the Revised Project’s energy consumption would
be typical of senior living development projects in Southern California and would not have any
unusual characteristics that would result in excessive energy consumption beyond the capacity of
SCE or SoCalGas. Similarly, the Revised Project would not conflict with or obstruct any plans for
renewable energy or energy efficiency, and no impact would occur. Therefore, there are no material
changes in circumstances, and the Revised Project would not result in any new significant or
substantially more severe environmental impacts that would affect the no-impact determination in
the 2020 MND.
5.7 GEOLOGY AND SOILS
Fault Rupture, Seismic Ground Shaking, Liquefaction, Unstable Soils, and Expansive Soils
According to the 2020 MND, the Project Site is near the Sierra Madre and Raymond Fault zones;
thus, it is in an area subject to strong ground shaking due to these and other regional faults. The
Project Site is also located within a liquefaction zone due to the relatively shallow groundwater
depth at the Project Site. However, the Project Site is located outside Alquist-Priolo Earthquake
Fault and Hazard Management Zones. The Project Site is also located in an area with potential
to contain expansive soils. The Approved Project would be required to adhere to building
regulations and seismic and building design standards that dictate seismic safety, earthquake-
resistant structural design, and structural integrity of structures to minimize the impacts resulting
from ground shaking, liquefaction, unstable soils (which may result in lateral spreading,
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 23
subsidence, or ground collapse), and expansive soils. Accordingly, with the Approved Project’s
adherence to applicable building regulations and seismic and building design standards, the 2020
MND determined that the Approved Project would not directly or indirectly cause potential
substantial adverse effects, including the risk of loss, injury, or death involving rupture of a known
earthquake fault, strong seismic ground shaking, liquefaction, lateral spreading, subsidence,
ground collapse, and expansive soils, and that impacts of the Approved Project related to these
issues would be less than significant.
As with the Approved Project, development of the Revised Project would be required to adhere
to the same building regulations and seismic and building design standards that would minimize
the impacts resulting from ground shaking, liquefaction, unstable soils, and expansive soils. With
adherence to such regulations and standards, the Revised Project would not result in impacts
related to these issues beyond those identified for the Approved Project. Therefore, there are no
material changes in circumstances, and the Revised Project would not result in any new
significant or substantially more severe environmental impacts that would affect the less-than-
significant impact determination in the 2020 MND.
Landslides
According to the 2020 MND and the City’s General Plan Safety Element, the Project Site is not
located within an earthquake-induced landslide hazard area. Therefore, the 2020 MND
determined that the Approved Project would not directly or indirectly cause potential substantial
adverse effects, including the risk of loss, injury, or death involving landslides, and no impact
related to landslides would occur.
As with the Approved Project, development of the Revised Project would occur within the
boundaries of the Project Site, where no earthquake-induced landslide hazard area has been
identified. Accordingly, development of the Revised Project would have no impact related to
landslides. Therefore, there are no material changes in circumstances, and the Revised Project
would not result in any new significant or substantially more severe environmental impacts that
would affect the no-impact determination in the 2020 MND.
Soil Erosion/Loss of Topsoil
According to the 2020 MND, because of the extensive ground alterations that have occurred on-
site from the development of the existing building (previously occupied by a Coco’s Bakery and
Restaurant) and the prior uses consisting of the Eaton’s Santa Anita Hotel and Restaurant, it is
unlikely that any native topsoil remains in the near surface, and, thus, no impact involving the loss
of topsoil would occur. However, during construction of the Approved Project, the uncovered soils
may become exposed to wind or rainstorms and thus be subject to erosion. Nonetheless, to
prevent stormwater-related erosion, the Approved Project would be required to comply with
existing regulations, including, but not limited to, SCAQMD Rule 403 to reduce wind erosion the
County of Los Angeles’ National Pollutant Discharge Elimination System (NPDES) Construction
General Permit requirements to reduce stormwater erosion. The Approved Project would also
prepare a Stormwater Pollution Prevention Plan (SWPPP) to establish erosion and sedimentation
controls as required by the City. Accordingly, with the Approved Project’s compliance with existing
regulations, the 2020 MND determined that the potential for soil erosion during construction
activity would be reduced to a less-than-significant level.
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 24
As with the Approved Project, development of the Revised Project would be required to comply
with the same regulations that would minimize the potential for soil erosion. Through compliance
with existing regulations, development of the Revised Project would not result in substantial soil
erosion beyond those identified for the Approved Project. Therefore, there are no material
changes in circumstances, and the Revised Project would not result in any new significant or
substantially more severe environmental impacts that would affect the less-than-significant impact
determination in the 2020 MND.
Paleontological Resources
According to the 2020 MND, no paleontological resources were identified on the Project Site.
However, the 2020 MND determined that the potential exists for encountering vertebrate
paleontological resources during grading activities for the Approved Project. To avoid the potential
destruction of paleontological resources and ensure proper identification and treatment of such
resources that may be discovered during grading, the 2020 MND identified the following mitigation
measure to reduce the potential impact of the Approved Project to paleontological resources to a
less-than-significant level:
GEO-1 Paleontological Resource Monitor. If paleontological resources (fossils) are
discovered during Project grading, work shall be halted in that area until a qualified
paleontologist can be retained to assess the significance of the find. The Project
paleontologist shall monitor remaining earth-moving activities at the Project Site and
shall be equipped to record and salvage fossil resources that may be unearthed
during grading activities. The paleontologist shall be empowered to temporarily halt
or divert grading equipment to allow recording and removal of the unearthed
resources. Any fossils found shall be evaluated in accordance with the CEQA
Guidelines and offered for curation at an accredited facility approved by the City of
Arcadia. Once grading activities have ceased or the paleontologist determines that
monitoring is no longer necessary, monitoring activities shall be discontinued.
As with the Approved Project, development of the Revised Project would include ground-
disturbing activities during construction and, as such, would result in potential impacts related to
the unanticipated discovery of paleontological resources. With implementation of Mitigation
Measure GEO-1 required for the Approved Project, development of the Revised Project would
not result in impacts to paleontological resources beyond those identified for the Approved
Project. Therefore, there are no material changes in circumstances, and the Revised Project
would not result in any new significant or substantially more severe environmental impacts that
would affect the determination of less-than-significant impact with mitigation in the 2020 MND.
5.8 GREENHOUSE GAS (GHG) EMISSIONS
According to the 2020 MND, the Approved Project would result in a net decrease in daily trips,
thereby causing a net decrease in GHG emissions over existing conditions. Accordingly, the 2020
MND determined that the Approved Project would generate levels of GHG emissions that would
have a less-than-significant impact on the environment. In addition, according to the 2020 MND,
the Approved Project would be consistent with the plans, policies, regulations, and GHG reduction
actions/strategies outlined in the 2017 CARB Scoping Plan and SCAG 2016-2040 RTP/SCS.
Therefore, the Approved Project would not conflict with any applicable plan, policy, or regulation
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 25
of an agency adopted for the purpose of reducing emissions of GHGs, and impacts would be less
than significant.
The Revised Project would involve a slightly larger development than analyzed in the 2020 MND.
In addition, because the restaurant occupying the existing building closed and has remained
vacant since the adoption of the 2020 MND, the trip credit from the restaurant use is no longer
applied. As a result, the Revised Project would emit a total of 598.30 metric tons of carbon dioxide
equivalent (MTCO2e) per year, which would be 801.95 MTCO2e per year higher than the
Approved Project, as shown in Table 5.
Table 5

mitigating GHG emissions. Since the adoption of the 2020 MND, the California Air Resources
Board (CARB) has adopted the 2022 Scoping Plan, and SCAG has adopted the 2020-2045
Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). Accordingly, the
evaluation of consistency with such plans is the sole basis for determining the significance of the
Revised Project’s GHG-related impacts on the environment. The 2022 Scoping Plan describes the
approach the State will take to achieve carbon neutrality by 2045, and the 2020-2045 RTP/SCS
includes strategies that will assist the region to reach the regional target of reducing GHG from
transportation sector.
The 2022 Scoping Plan identifies reduction measures necessary to achieve the goal of carbon
neutrality by 2045 or earlier. Actions that reduce GHG emissions are identified for each Assembly
Bill (AB) 32 inventory sector. An evaluation of applicable reduction actions/strategies by emissions
source category to determine how the Revised Project would be consistent with or exceed reduction
actions/strategies outlined in the 2022 Scoping Plan is provided in Table 6.

Smart Growth/Vehicles Miles Traveled (VMT)
Reduce VMT per capita to
25% below 2019 levels by
2030, and 30% below
2019 levels by 2045
Consistent. The Revised Project would provide a dining room, a café, a laundry
room, a sensory wellness room, a reading room, a sitting and music area, a beauty
salon, a fitness center with a physical therapy area, a bar/lounge, an activity room,
a media room, and separate open-air courtyards and outdoor spaces. Providing
these amenities on-site would reduce VMT as the residents do not need to drive
off-site for services. In addition, the residents are anticipated to have limited
mobility and, as such, are expected to generate a very small number of vehicle
trips. Furthermore, the Revised Project would provide bicycle parking, which
would promote an alternative mode of transportation for visitors and employees.
As such, the Revised Project would be consistent with this action.
New Residential and Commercial Buildings
All electric appliances

Consistent. The City of Arcadia has not adopted an ordinance or program limiting
the use of natural gas for on-site cooking and/or heating. However, if such an
ordinance is adopted, the Revised Project would be required to comply with the
applicable goals or policies limiting the use of natural gas equipment in the future.
Furthermore, the Revised Project would install high efficiency lighting and
appliances. As such, the Revised Project would be consistent with this action.
Construction Equipment
25% of energy demand
electrified by 2030 and
75% electrified by 2045
Consistent. The City of Arcadia has not adopted an ordinance or program
requiring electric-powered construction equipment. However, if such an
ordinance is adopted, the Revised Project would be required to comply with the
applicable goals or policies requiring the use of electric construction equipment
in the future. As such, the Revised Project would be consistent with this action.
Non-combustion Methane Emissions
Divert 75% of organic
waste from landfills by
2025
Consistent. SB 1383 establishes targets to achieve a 50 percent reduction in
the level of the statewide disposal of organic waste from the 2014 level by 2020
and a 75 percent reduction by 2025. The Revised Project would comply with
local and regional regulations and recycle or compost 75 percent of waste by
2025 pursuant to SB 1383. As such, the Revised Project would be consistent
with this action.

The 2020-2045 RTP/SCS includes performance goals that were adopted to help focus future
investments on the best-performing projects, as well as different strategies to preserve, maintain,
and optimize the performance of the existing transportation system. The SCAG 2020-2045
RTP/SCS is forecast to help California reach its GHG emissions reduction goals by reducing GHG
emissions from passenger cars by 8 percent below 2005 levels by 2020 and 19 percent by 2035 in
accordance with the California Air Resources Board targets adopted in March 2018. Five key SCS
strategies are included in the 2020-2045 RTP/SCS to help the region meet its regional vehicle miles
traveled (VMT) and GHG reduction goals, as required by the State.
Table 7 presents the Revised Project’s consistency with these five strategies. As shown therein,
the Revised Project would be consistent with the GHG emission reduction strategies contained in
the 2020-2045 RTP/SCS.

In summary, the Revised Project’s characteristics render it consistent with statewide, regional, and
local climate change mandates, plans, policies, and recommendations. More specifically, the GHG
plan consistency analysis demonstrates that the Revised Project would comply with the regulations
and GHG reduction goals, policies, actions, and strategies outlined in the 2022 Scoping Plan and
2020-2045 RTP/SCS. Consistency with these plans would reduce the impact of the Revised
Project’s incremental contribution of GHG emissions. Accordingly, the Revised Project would not
conflict with any applicable plan, policy, regulation, or recommendation adopted for the purpose of
reducing GHG emissions. Impacts in this regard would be less than significant. Therefore, there are
no material changes in circumstances, and the Revised Project would not result in any new
significant or substantially more severe environmental impacts that would affect the determination
of less-than-significant impact in the 2020 MND.
5.9 HAZARDS AND HAZARDOUS MATERIALS
Routine Transport, Use, Disposal, or Accidental Release of Hazardous Materials
According to the 2020 MND, given the age of the existing restaurant building on-site (constructed
in the 1970s), there is potential for the building to contain asbestos-containing materials (ACM)
and/or lead-based paint (LBP). However, the Approved Project would be required to comply with
existing regulations to properly identify, remove, handle, and dispose of ACMs and LBP.
Compliance with these regulations would ensure that existing hazardous materials would be
effectively disposed of during the demolition phase and would, therefore, have no effect on the
health and safety of construction workers and area residents. In addition, the transport, use, and
disposal of hazardous materials, as well as the potential release of these materials to the
environment, are closely regulated through State and federal laws. Furthermore, the use of
hazardous materials during operation of the Approved Project would likely involve minor quantities
of typical household hazardous materials, such as cleaning products, solvents, adhesives,

therefore, would not interfere with

emissions. Thus, the Revised Project
would support efficient development
that reduces energy consumption and
GHG emissions. The Revised Project

refrigerants, paints, other chemical materials used in building maintenance, small amounts of oil
and fuels from internal combustion engines, pesticides and herbicides, sharp or used needles,
and electronic waste. This level of hazardous materials use would be typical for institutional uses
and, thus, is not identified as a significant threat to the environment. Accordingly, the 2020 MND
determined that based on the type of land use proposed, the relatively minor anticipated level of
use, storage, and disposal of hazardous materials and compliance with various State and federal
laws regulating hazardous materials, the Approved Project would result in a less-than-significant
impact involving the routine transport, use, or disposal of hazardous materials or the accidental
release of hazardous materials into the environment.
The Revised Project proposes the same land use type as the Approved Project and would not
include land uses that may generate hazardous materials or hazardous waste beyond those
identified for the Approved Project. As with the Approved Project, the Revised Project would be
required to comply with the same regulations that would minimize the impacts to the public and
the environment as related to the routine transport, use, or disposal of hazardous materials or the
accidental release of hazardous materials into the environment, including the removal of ACM
and LBP if found on-site. Therefore, there are no material changes in circumstances, and the
Revised Project would not result in any new significant or substantially more severe environmental
impacts that would affect the less-than-significant impact determination in the 2020 MND.
Impacts Related to Hazardous Emissions, Cortese List Site, Airports, and Wildland Fires
According to the 2020 MND, there are no schools within a quarter mile of the Project Site, and,
as such, the Approved Project would not emit hazardous emissions or handle hazardous or
acutely hazardous materials, substances, or waste within a quarter mile of an existing or proposed
school. In addition, the Project Site is not included on the Cortese List, which is the list of
hazardous waste sites or facilities compiled by the California Department of Toxic Substances
Control under Government Code Section 65962.5. As such, the Approved Project would not
create a significant hazard to the public or the environment. Furthermore, the nearest airport to
the Project Site is the San Gabriel Airport, which is approximately 4.5 miles to the southeast, and,
as such, the Approved Project would not result in a safety hazard or excessive noise for people
residing or working in the Project area. Finally, the Project Site is not located within a Very High
Fire Hazard Severity Zone, as identified by the California Department of Forestry and Fire
Protection, or surrounded by wildland areas. As such, the Approved Project would not expose
people or structures to a significant risk of loss, injury, or death involving wildland fire. Accordingly,
the 2020 MND determined that the Approved Project would have no impact related to these
issues.
The Revised Project would be developed within the boundaries of the Project Site and proposes
the same land use type as the Approved Project. Accordingly, as with the Approved Project, the
Revised Project would have no impact related to hazardous emissions near schools, creating a
hazard as a hazardous waste site, airport safety hazards, or wildland fires. Therefore, there are
no material changes in circumstances, and the Revised Project would not result in any new
significant or substantially more severe environmental impacts that would affect the no-impact
determination in the 2020 MND.
Emergency Evacuation Plan
Access to the Project Site is currently available on Michillinda Avenue and Colorado Boulevard.
According to the 2020 MND, the Approved Project would have access to major thoroughfares that
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 31
have been identified as a Principal Travel Corridor by the City’s General Plan, such as Michillinda
Avenue, I-210, and Foothill Boulevard, during an emergency evacuation. In addition, the
Approved Project would reduce the number of daily trips and peak hour trips generated by the
Coco’s Bakery and Restaurant, which was in operation at the time, thereby reducing traffic on
adjacent and nearby thoroughfares. Therefore, the 2020 MND determined that development of
the Approved Project would not impair implementation of an adopted emergency response plan
or evacuation plan.
The Revised Project proposes the same land use type as the Approved Project and would not
include land uses that may interfere with or obstruct emergency evacuation of the Project Site
and the Project vicinity. As with the Approved Project, the Revised Project would have access to
major thoroughfares during an emergency evacuation. The Revised Project would generate no
more than 30 vehicle trips in the peak hours, as presented in Appendix B of this Initial Study.
This minimal increase in peak hour trips would have a negligible impact on the area intersections.
Accordingly, as with the Approved Project, development of the Revised Project would not impair
implementation of an adopted emergency response plan or evacuation plan. Therefore, there are
no material changes in circumstances, and the Revised Project would not result in any new
significant or substantially more severe environmental impacts that would affect the less-than-
significant impact determination in the 2020 MND.
5.10 HYDROLOGY AND WATER QUALITY
Water Quality
According to the 2020 MND, the Approved Project could have both short- and long-term impacts
on water quality. Short-term impacts would occur during the construction phase, when the
pollutants of greatest concern are sediment and hydrocarbon or fossil fuel remnants, which could
run off the Project Site without any best management practices (BMPs) in place. Long-term
impacts would result from stormwater runoff from the Project Site during operation of the
Approved Project. However, construction runoff is regulated by the NPDES Construction General
Permit, which requires identification of a variety of water quality control BMPs to be specified on
construction plans and implemented throughout construction. Similarly, the Approved Project
would be required to comply with the City’s Low Impact Development (LID) Ordinance, which
requires the preparation of a LID Plan that addresses on-site stormwater runoff retention and
treatment and implementation of post-construction BMPs, such as cleaning the parking areas and
the sidewalks along the Project Site’s frontages. Accordingly, the 2020 MND determined that
through compliance with existing regulations and the preparation of a LID Plan, potential water
quality impacts during construction and operation of the Approved Project would be avoided or
reduced to less-than-significant levels, and the Approved Project would not result in violations of
any water quality standards or waste discharge requirements.
As with the Approved Project, the Revised Project would be required to comply with the same
regulations that would minimize the impacts on water quality, including the preparation of a LID
Plan, and, as such, would not substantially degrade surface or groundwater quality and result in
impacts beyond those identified for the Approved Project. Therefore, there are no material
changes in circumstances, and the Revised Project would not result in any new significant or
substantially more severe environmental impacts that would affect the less-than-significant impact
determination in the 2020 MND.
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 32
Groundwater
According to the 2020 MND, there are no groundwater wells on the Project Site, and none were
proposed by the Approved Project. The Approved Project would reduce, but not substantially
change, the amount of impervious surface area on-site and, as such, would not have an effect on
groundwater levels beneath the Project Site; if any, the effect would be minimal and likely
beneficial given the Approved Project’s reduction in overall impervious surfaces as compared to
existing conditions. As such, operation of the Approved Project would not interfere with
groundwater recharge. Accordingly, the Approved Project would not substantially decrease
groundwater supplies or interfere substantially with groundwater recharge such that the Approved
Project may impede sustainable groundwater management of the basin. Therefore, impacts to
groundwater would be less than significant.
As with the Approved Project, development of the Revised Project would not substantially change
the amount of impervious surface area on-site and would not have an effect on groundwater levels
beneath the Project Site. Similar to the Approved Project, the Revised Project would likely have
a beneficial effect given the reduction in overall impervious surfaces as compared to existing
conditions. Accordingly, the Revised Project would not substantially decrease groundwater
supplies or interfere substantially with groundwater recharge such that the Revised Project may
impede sustainable groundwater management of the basin, and impacts would be less than
significant. Therefore, there are no material changes in circumstances, and the Revised Project
would not result in any new significant or substantially more severe environmental impacts that
would affect the less-than-significant impact determination in the 2020 MND.
Drainage
According to the 2020 MND, there are no natural drainage courses on the Project Site, and,
because the Project Site is currently fully developed with impervious surfaces, the Approved
Project would not result in a substantial alteration of the existing drainage pattern of the Project
Site. The Approved Project would be required to comply with existing regulations to (1) minimize
erosion that may lead to siltation on- or off-site during construction; (2) ensure proper drainage to
avoid or redirect flooding on- or off-site; and (3) prevent discharge of sediment and polluted
stormwater runoff, and retain, control, and treat stormwater runoff on the Project Site. Accordingly,
the 2020 MND determined that the Approved Project would not alter the existing drainage pattern
of the Project Site in a manner that would result in substantial erosion or siltation on- or off-site,
substantially increase the rate or amount of surface runoff in a manner that would result in flooding
on- or off-site, create or contribute runoff water that would exceed the capacity of the existing
stormwater drainage system or provide substantial additional sources of polluted runoff, or
impede or redirect flood flows. Therefore, impacts related to drainage would be less than
significant.
As with the Approved Project, development of the Revised Project would not substantially change
the amount of impervious surface area on-site as compared to existing conditions. In addition, the
Revised Project would be required to comply with same existing regulations as the Approved
Project. Furthermore, similar to the Approved Project, the Revised Project would likely have a
beneficial effect given the reduction in overall impervious surfaces as compared to existing
conditions. A modular wetland is proposed in the southeastern corner of the Project Site to collect
and treat surface water runoff from the Project Site prior to draining to the existing curb inlet and
then to the existing storm drainage system to the east. Accordingly, the Revised Project would

not alter the existing drainage pattern of the Project Site that would result in flooding on- or off-
site, create or contribute runoff water that would exceed the capacity of the existing stormwater
drainage system or provide substantial additional sources of polluted runoff, or impede or redirect
flood flows; as such, impacts would be less than significant. Therefore, there are no material
changes in circumstances, and the Revised Project would not result in any new significant or
substantially more severe environmental impacts that would affect the less-than-significant impact
determination in the 2020 MND.
Flooding
According to the 2020 MND, the Project Site is not located near any reservoir, other bodies of
water, or the Pacific Ocean to be potentially inundated by seiches or tsunamis. According to the
Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map for the area, the
Project Site is located within Zone X, which represents an area of minimal flood hazard. However,
according to the City’s General Plan Safety Element, the Project Site is located within a
designated inundation area for the Morris S. Jones Reservoir. Nonetheless, dams are regulated
and monitored for structural safety by the California Department of Water Resources in
accordance with the California Water Code to reduce the potential for catastrophic failure and
inundation of downstream areas, such as the Project Site. In addition, the Approved Project would
be required to implement a LID plan, which would incorporate water quality control features on-
site, such as maintenance of landscape areas and proper storage of any hazardous materials,
which would prevent the release of pollutants in the unlikely event that the Project Site is
inundated by catastrophic dam failure. Therefore, the 2020 MND determined that the Approved
Project would not risk release of pollutants due to inundation, and no impact would occur.
As with the Approved Project, development of the Revised Project would occur within the
boundaries of the Project Site, which has been identified as not being subject to inundation by
seiches or tsunamis. Given that the Revised Project is located within a designated inundation
area for the Morris S. Jones Reservoir, the Revised Project would be required to implement water
quality control features on-site to prevent the release of pollutants when inundated. Accordingly,
the Revised Project would not risk release of pollutants due to inundation, and no impact would
occur. Therefore, there are no material changes in circumstances, and the Revised Project would
not result in any new significant or substantially more severe environmental impacts that would
affect the no-impact determination in the 2020 MND.
Consistency with Water Quality Control Plan or Sustainable Groundwater Management
Plan
According to the 2020 MND, because the Approved Project would not result in a substantial
increase in potable water demand and because it would not involve the use, disposal, or storage
of hazardous chemicals that could impact water quality, the Approved Project would not interfere
with the Main Basin Watermaster’s 2019 Supply Plan, and impacts would be less than significant.
Although the Revised Project would consume and generate more water and wastewater,
respectively, than the Approved Project, the Revised Project would also not result in a substantial
increase in potable water demand. As discussed in Section 5.19, Utilities/Service Systems, of this
addendum, because the Revised Project is consistent with the underlying zoning and General
Plan designation for the Project Site, the population and employment growth associated with the
Revised Project would have been incorporated into the SCAG 2020-2045 RTP/SCS growth
projections, on which the City’s 2020 Urban Water Management Plan (UWMP) was based.
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 34
According to the 2020 UWMP, the City can meet water demands during normal years, single dry
years, and five consecutive year drought periods through 2045.2 In addition, as with the Approved
Project, because the Revised Project would not involve the use, disposal, or storage of hazardous
chemicals that could impact water quality, the Revised Project would not interfere with the Main
Basin Watermaster’s 2019 Supply Plan, and impacts would be less than significant. Therefore,
there are no material changes in circumstances, and the Revised Project would not result in any
new significant or substantially more severe environmental impacts that would affect the less-
than-significant impact determination in the 2020 MND.
5.11 LAND USE AND PLANNING
Physical Division of an Established Community
According to the 2020 MND, the Approved Project would not result in physical alterations to any
land use beyond the Project Site boundaries or significant changes to the public rights-of-way
beyond the widening of Colorado Boulevard and Michillinda Avenue along the Project Site’s
frontages to be implemented by the City following the Approved Project’s 4-foot dedication from
the Project Site. Therefore, the 2020 MND determined that the Approved Project would not
physically divide an established community, and no impact would occur.
As with the Approved Project, development of the Revised Project would occur on the Project
Site and, as such, would not result in physical alterations to any land use beyond the Project Site
boundaries. Similar to the Approved Project, the Revised Project would dedicate 4 feet from the
Project Site to allow the City to improve and widen Colorado Boulevard and Michillinda Avenue
along the Project Sites frontages. In addition, the Revised Project would connect to an existing
21-inch sewer main to the west along Michillinda Avenue via a new sewer lateral. However, as
with the Approved Project, the Revised Project would not physically divide an established
community, and no impact would occur. Therefore, there are no material changes in
circumstances, and the Revised Project would not result in any new significant or substantially
more severe environmental impacts that would affect the no-impact determination in the 2020
MND.
Conflict with Plans, Policies, or Regulations
According to the 2020 MND, the Approved Project would be consistent with the development
standards and regulation of the underlying C-G zone upon approval of a CUP. In addition, the
Arcadia General Plan Parks, Recreation, and Community Resources Element and the Safety
Element do not identify any land use restrictions for the Project Site that, respectively, (1) would
require conservation of the Project Site for purposes of protecting wildlife habitat or other natural
resources or (2) pertain to avoidance of environmental hazards on or near the Project Site. The
Project Site is not within an area where special land use policies or zoning standards have been
created for the purpose of avoiding or mitigating environmental effects. Accordingly, the 2020
MND determined that the Approved Project would not conflict with an applicable land use plan,
policy, or regulation established for the purpose of avoiding or mitigating an environmental effect,
and impacts related to land use and planning would be less than significant.
As with the Approved Project, development of the Revised Project would occur on the Project
Site and not within an area where special land use policies or zoning standards have been created
2 City of Arcadia, Final 2020 Urban Water Management Plan , June 2021.
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 35
for the purpose of avoiding or mitigating environmental effects. Additionally, the Revised Project
would be consistent with the existing General Plan Land Use designation of Commercial and zone
of G-C. As discussed in Section 4.0, Project Description, of this addendum, the Revised Project
is entitled to receive a density bonus and deviate from the maximum permitted FAR for the Project
Site through a CUP; the Revised Project would comply with all other applicable development
standards. Accordingly, as with the Approved Project, the Revised Project would not conflict with
an applicable land use plan, policy, or regulation established for the purpose of avoiding or
mitigating an environmental effect, and impacts related to land use and planning would be less
than significant. Therefore, there are no material changes in circumstances, and the Revised
Project would not result in any new significant or substantially more severe environmental impacts
that would affect the less-than-significant impact determination in the 2020 MND.
5.12 MINERAL RESOURCES
According to the 2020 MND, since the Project Site is currently developed with a building
previously occupied by Coco’s Bakery and Restaurant and surface parking, development of the
Approved Project on the Project Site would not result in the loss of availability of (1) a known
mineral resource that would be of regional or Statewide value or (2) a locally-important mineral
resource recovery site. Accordingly, the 2020 MND determined that the Approved Project would
have no impact to mineral resources.
As with the Approved Project, development of the Revised Project would occur within the Project
Site boundaries and, as such, would not result in the loss of a known mineral resource or a locally-
important mineral resource recovery site. Therefore, there are no material changes in
circumstances, and the Revised Project would not result in any new significant or substantially
more severe environmental impacts that would affect the no-impact determination in the 2020
MND.
5.13 NOISE
Temporary or Permanent Increase in Ambient Noise Levels
According to the 2020 MND, although construction noise is allowed during the City’s allowable
construction hours and is not considered to be a significant impact during those hours,
construction of the Approved Project could expose adjoining residential uses to temporary high
noise levels. To reduce the short-term construction impacts on adjacent sensitive receptors to
less-than-significant levels, the 2020 MND identified the following mitigation measure:
NOI-1 Prior to issuance of a Grading Permit, the Project applicant shall demonstrate, to the
satisfaction of the City of Arcadia Planning Division, that the Project complies with
the following:
x Construction contracts specify that all construction equipment, fixed or mobile,
shall be equipped with properly operating and maintained mufflers and other
State-required noise attenuation devices.
x The contractor shall provide evidence that a construction staff member will be
designated as a noise disturbance coordinator and will be present on-site during
construction activities. The noise disturbance coordinator shall be responsible
for responding to any local complaints about construction noise. When a
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 36
complaint is received, the noise disturbance coordinator shall notify the City
within 24 hours of the complaint and determine the cause of the noise complaint
(e.g., starting too early or bad muffler) and shall implement reasonable measures
to resolve the complaint, as deemed acceptable by the Planning & Community
Development Administrator (or designee). All notices that are sent to residential
units immediately surrounding the construction site and all signs posted at the
construction site shall include the contact name and the telephone number for
the noise disturbance coordinator. All necessary signage and notices shall be
posted on or sent to residential units immediately surrounding the construction
site no less than two weeks prior to the start of noise-generating construction
activities on the Project Site.
x During construction, stationary construction equipment shall be placed such that
emitted noise is directed away from sensitive noise receivers.
x Prior to issuance of any Grading or Building Permit, the Project applicant shall
demonstrate to the satisfaction of the Community Development Director (or
designee) that construction noise reduction methods shall be used where
feasible. These reduction methods may include shutting off idling equipment,
installing temporary acoustic barriers around stationary construction noise
sources, maximizing the distance between construction equipment staging areas
and occupied residential areas, and utilizing electric air compressors and similar
power tools.
x Construction haul routes shall be designed to avoid noise-sensitive uses (e.g.,
residences and convalescent homes) to the extent feasible.
In addition, according to the 2020 MND, the Approved Project would generate fewer trips when
compared to the existing use on the Project Site at the time (i.e., Coco’s Bakery and Restaurant).
As such, the 2020 MND determined that, because the Approved Project’s trip generation would
reduce existing traffic volumes along local roadways, traffic noise levels also would be reduced
and would be less than significant. Additionally, the 2020 MND determined that the Approved
Project’s operational stationary noise associated with mechanical equipment, slow-moving trucks,
and parking areas would not exceed the City’s noise standards or introduce new sources of noise
in the Project vicinity compared to existing conditions. Therefore, operation of the Approved
Project was determined to result in less-than-significant noise impacts in the 2020 MND.
As with the Approved Project, development of the Revised Project would occur within the
boundaries of the Project Site, with sensitive receptors located immediately adjacent to the east
and south. Although the Revised Project would involve a slightly larger development and, thus,
longer construction duration than analyzed in the 2020 MND, there would be no change in the
construction equipment anticipated to be used or the distance between the closest receptors and
the proposed construction activities. As with the Approved Project, although construction noise is
allowed during the City’s allowable construction hours and is not considered to be a significant
impact during those hours, the Revised Project could expose adjoining residential uses to
temporary high noise levels and would, therefore, be required to comply with Mitigation Measure
NOI-1 to reduce short-term construction noise impacts to less-than-significant levels. Therefore,
there are no material changes in circumstances, and the Revised Project would not result in any
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 37
new significant or substantially more severe environmental impacts that would affect the
determination of less-than-significant impact with mitigation in the 2020 MND.
As discussed in Section 5.17, Transportation/Traffic, of this addendum, the Revised Project would
generate more trips compared to the Approved Project. However, the Revised Project would only
add 17 or fewer trips to the two driveways when compared to the Approved Project; this increase
in traffic would be equivalent to an average of no more than 1 trip every 3.5 minutes and, as such,
would have a negligible impact on the area intersections. In addition, according to the City of
Arcadia Traffic Volume Map, existing daily traffic volumes along Colorado Street and Michillinda
Avenue are 20,842 and 18,522 trips per day, respectively.3 As determined by the California
Department of Transportation, a doubling in roadway traffic volumes is required to generate any
noticeable increase in roadway noise levels.4 Accordingly, the Revised Project’s minimal trip
generation of approximately 296 trips per day (compared to the 208 trips per day generated by
the Approved Project) would not double existing traffic volumes along Colorado Boulevard and
Michillinda Avenue or result in a perceptible increase in traffic noise. In addition, the Revised
Project proposes the same land use type as the Approved Project and would not include
stationary sources, such as mechanical equipment, slow-moving trucks, and parking areas,
beyond those identified for the Approved Project. Therefore, the Revised Project’s operational
stationary noise levels would not exceed the City’s noise standards or introduce new sources of
noise in the Project vicinity compared to existing conditions and would be considered less than
significant. Therefore, there are no material changes in circumstances, and the Revised Project
would not result in any new significant or substantially more severe environmental impacts that
would affect the less-than-significant impact determination in the 2020 MND.
Groundborne Vibration
According to the 2020 MND, construction of the Approved Project would not generate
groundborne vibration exceeding the building damage or human annoyance thresholds
established by the Federal Transit Administration. Similarly, operation of the Approved Project
would not include uses that would generate excessive groundborne vibration. Accordingly, the
2020 MND determined that the Approved Project would not result in excessive groundborne
vibration or groundborne noise levels, and impacts would be less than significant.
As with the Approved Project, development of the Revised Project would occur within the
boundaries of the Project Site, with sensitive receptors located immediately adjacent to the east
and south. Although the Revised Project would involve a larger development and longer
construction duration than analyzed in the 2020 MND, there would be no change in the
construction equipment anticipated to be used or the distance between the closest receptors and
the proposed construction activities. Accordingly, construction and operation of the Revised
Project would not generate groundborne vibration exceeding the building damage or human
annoyance thresholds or include uses that would generate excessive groundborne vibration
beyond those identified for the Approved Project. Therefore, there are no material changes in
circumstances, and the Revised Project would not result in any new significant or substantially more
severe environmental impacts that would affect the less-than-significant impact determination in the
2020 MND.

Airport-Related Noise
As discussed in Section 5.9, Hazards and Hazardous Materials, of this addendum, the nearest
airport to the Project Site is the San Gabriel Airport, which is approximately 4.5 miles to the
southeast, and, as such, the Approved Project would not result in a safety hazard or excessive
noise for people residing or working in the Project area. Accordingly, the 2020 MND determined
that the Approved Project would have no impact related to excessive noise levels associated with
aircraft operation.
The Revised Project would be developed within the boundaries of the Project Site and proposes
the same land use type as the Approved Project. Accordingly, as with the Approved Project, the
Revised Project would have no impact related to excessive noise levels associated with aircraft
operation. Therefore, there are no material changes in circumstances, and the Revised Project
would not result in any new significant or substantially more severe environmental impacts that
would affect the no-impact determination in the 2020 MND.
5.14 POPULATION AND HOUSING
According to the 2020 MND, the Approved Project, which was estimated to generate 80 residents
and 40 employees,5 would account for approximately 0.9 percent of the forecasted population
growth and 0.7 percent of the forecasted employment growth between 2012 and 2040 as
projected in the SCAG 2016-2020 RTP/SCS.6 The 2020 MND determined that the Approved
Project would not result in substantial unplanned growth in the area, and impacts would be less
than significant.
The Revised Project would have 114 beds, resulting in the generation of 114 residents. Using the
same assumption (based on SCAG’s Employment Density Report) as that for the Approved
Project, the Revised Project is also estimated to generate 40 employees. The SCAG 2020-2045
RTP/SCS, the update to the 2016-2040 RTP/SCS, estimates that the City’s population would
increase by 4,900 residents and 2,800 employees between 2016 and 2045. Accordingly, the
Revised Project’s residents and employees would account for approximately 2.3 percent of the
forecasted population growth and 1.4 percent of the forecasted employment growth between 2016
and 2045. Although the Revised Project would increase the number of residents and employees
and the corresponding percentages in forecasted growth, the Revised Project would remain
consistent with the zoning and General Plan land use designation for the Project Site pursuant to
the California Density Bonus Law, as discussed in Section 4.0, Project Description, of this
addendum. As with the Approved Project, the Revised Project would not result in substantial
unplanned growth in the area, and impacts would be less than significant. Therefore, there are no
material changes in circumstances, and the Revised Project would not result in any new significant
or substantially more severe environmental impacts that would affect the less-than-significant
impact determination in the 2020 MND.
With regard to displacement of people or housing, the Project Site contains an existing building,
which was previously occupied by Coco’s Bakery and Restaurant and is now vacant, and surface
5 According to the 2020 MND, the number of employees was calculated using SCAG’s Employment Density
Report (Employment Density Study Summary Report, Table B-1, 2001), which provided an average employee
density of 14.24 employees per acre for Special Care Facilities in Los Angeles County. As the Project Site is
2.79 acres in size, the estimated number of employees serving the Approved Project would be 40.
6 The 2016-2040 RTP/SCS estimated that the population in Arcadia would increase from 56,700 to 65,900 and
employment from 28,900 to 34,400 between 2012 and 2040.
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 39
parking. Accordingly, because there are no current residents or housing units on the Project Site,
the Approved Project would not displace people or housing, necessitating the construction of
replacement housing elsewhere. As such, no impact related to displacement would occur. As with
the Approved Project, the Revised Project would occur within the Project Site boundaries and, thus,
would not displace people or housing. Therefore, there are no material changes in circumstances,
and the Revised Project would not result in any new significant or substantially more severe
environmental impacts that would affect the no-impact determination in the 2020 MND.
5.15 PUBLIC SERVICES
Fire and Police Protection
According to the 2020 MND, the Approved Project would incrementally increase the demand for
fire and police protection services. However, the Approved Project would be required to comply
with the California Fire Code and Arcadia Fire Department regulations governing hydrant
placement, fire flows, and building construction, and with the Arcadia Fire Department’s review
and approval of the Project Site’s access and circulation plans. With regard to police protection,
the Approved Project would include on-site security resources, such as security guards and
orderlies, to patrol the grounds, monitor locked entry and exit points to the property, and protect
residents. In addition, the Approved Project would be required to comply with Policy S-5.11 of the
Arcadia General Plan and pay its fair share of costs associated with any necessary increases in
public safety equipment, facilities, and staffing to provide life safety protection. Accordingly,
through compliance with existing regulations and incorporation of safety and security features in
the design of the proposed development, the Approved Project would have a less-than-significant
impact on fire and police protection services.
As with the Approved Project, the Revised Project would incrementally increase the demand for
fire protection and emergency medical services. Although the Revised Project would generate 34
additional residents than the Approved Project, the Revised Project would not present unique or
more difficult circumstances than the Approved Project that would warrant new or expanded fire
or police protection services or facilities. As with the Approved Project, the Revised Project would
be required to comply with existing regulations and incorporate safety and security features in the
design of the proposed development resulting in a less-than-significant impact on fire and police
protection services. Therefore, there are no material changes in circumstances, and the Revised
Project would not result in any new significant or substantially more severe environmental impacts
that would affect the less-than-significant impact determination in the 2020 MND.
Schools, Parks, and Other Public Facilities
According to the 2020 MND, because the Approved Project would be inhabited by seniors
affected by memory loss, there would be no school-aged children living on the Project Site that
would incrementally increase the demand for schools. In addition, the residents of the Approved
Project were anticipated to have limited mobility and, thus, not expected to substantially increase
the demand on parks, libraries, and other public facilities. Furthermore, the Approved Project
would include activity rooms, enclosed landscaped outdoor area with gardens, walking paths, and
a gazebo for use by the Project’s residents. Accordingly, the 2020 MND determined that the
Approved Project would have no impact on schools, City park facilities, libraries, and other public
facilities.
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 40
As with the Approved Project, the Revised Project would be inhabited by seniors affected by
memory loss, and, as such, no school-aged children would be living on the Project Site. Similarly,
the residents of the Revised Project are anticipated to have limited mobility and are not expected
to substantially increase the demand on parks, libraries, and other public facilities. As with the
Approved Project, the Revised Project would provide indoor recreational amenities, such as a
reading room, sitting and music areas, sensory wellness room, a bar/lounge, an activity room, a
media room, and a fitness center with a physical therapy area, and outdoor recreational amenities,
such as open air courtyards, a seating area with outdoor workout equipment, a dog park, and a
bocce ball court, for use by the Project’s residents. Accordingly, as with the Approved Project, the
Revised Project would have no impact on schools, City park facilities, libraries, and other public
facilities. Therefore, there are no material changes in circumstances, and the Revised Project would
not result in any new significant or substantially more severe environmental impacts that would
affect the no-impact determination in the 2020 MND.
5.16 RECREATION
As discussed in Section 5.16, Public Services (Parks), residents of the Approved Project were
expected to have limited mobility and, thus, not expected to increase the demand on parks or
other recreational facilities. In addition, the Approved Project would include activities rooms,
enclosed landscaped outdoor area with gardens, walking paths, and a gazebo for use by the
Project’s residents. Accordingly, the 2020 MND determined that the Approved Project would have
no impact on parks or other recreational facilities such that substantial physical deterioration of
the facility would occur or be accelerated.
As with the Approved Project, the residents of the Revised Project are anticipated to have limited
mobility and are not expected to substantially increase the demand on parks or other recreational
facilities. As with the Approved Project, the Revised Project would provide indoor recreational
amenities, such as a reading room, sitting and music areas, sensory wellness room, a bar/lounge,
an activity room, a media room, and a fitness center with a physical therapy area, and outdoor
recreational amenities, such as open air courtyards, a seating area with outdoor workout
equipment, a dog park, and a bocce ball court, for use by the Project’s residents. Accordingly, as
with the Approved Project, the Revised Project would have no impact on parks or other
recreational facilities. Therefore, there are no material changes in circumstances, and the Revised
Project would not result in any new significant or substantially more severe environmental impacts
that would affect the no-impact determination in the 2020 MND.
5.17 TRANSPORTATION/TRAFFIC
Conflict with Plans, Policies, or Regulations
According to the 2020 MND, while the Approved Project’s construction traffic would temporarily
affect traffic flow on the surrounding street network, particularly along the truck haul routes, the
impacts would be temporary and would fluctuate in intensity throughout the construction day and
vary throughout the overall construction program, with less traffic generated in phases following
the demolition and grading phases. Accordingly, the 2020 MND determined that, because the
construction traffic impacts associated with the Approved Project would be temporary, they would
not significantly affect the performance of the circulation system with respect to level of service
standards or other metrics related to congestion and travel delay. During operation, the Approved
Project would generate fewer trips when compared to the existing use on the Project Site at the
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 41
time (i.e., Coco’s Bakery and Restaurant), resulting in a less-than-significant impact related to trip
generation, trip distribution, and intersection performance. In addition, the residents of the
Approved Project were anticipated to have limited mobility and, as such, would have little to no
impact on surrounding bus, pedestrian, or bicycle facilities. Project employees were anticipated
to have a small impact on bus, pedestrian, or bicycle systems as the number of employees and
visitors that would utilize transit or bicycle infrastructure to access the senior living and memory
care facility under the Approved Project as compared to those of the existing use of the Project
Site at the time was deemed negligible. Accordingly, the 2020 MND determined that the Approved
Project would not conflict with a program, plan, ordinance, or policy addressing the circulation
system, taking into account all modes of transportation including transit, roadways, bicycle and
pedestrian facilities; as such, impacts related to transportation would be less than significant.
The Revised Project proposes the same land use type as the Approved Project and would
temporarily affect traffic flow on the surrounding street network during construction. As with the
Approved Project, the short-term nature of the construction traffic impacts would not significantly
affect the performance of the circulation system with respect to level of service standards or other
metrics related to congestion and travel delay. During operation, because the Revised Project
would involve a larger development than analyzed in the 2020 MND and the trip credit from the
restaurant use is no longer applied due to its closing, the Revised Project would generate more
trips compared to the Approved Project (see Appendix B). However, the Revised Project would
only add 17 or fewer trips to the two driveways when compared to the Approved Project; this
increase in traffic would be equivalent to an average of no more than 1 trip every 3.5 minutes and,
as such, would have a negligible impact on the area intersections. As with the Approved Project,
the residents of the Revised Project are anticipated to have limited mobility and, as such, would
have little to no impact on surrounding bus, pedestrian, or bicycle facilities. In addition, because
the number of employees under the Revised Project would be the same as that under the
Approved Project employees, as discussed in Section 5.14, Population and Housing, of this
addendum, the Revised Project would not result in impacts on bus, pedestrian, or bicycle systems
beyond those identified for the Approved Project. Accordingly, as with the Approved Project, the
Revised Project would not conflict with a program, plan, ordinance, or policy addressing the
circulation system, taking into account all modes of transportation including transit, roadways,
bicycle and pedestrian facilities; as such, impacts related to transportation would be less than
significant. Therefore, there are no material changes in circumstances, and the Revised Project
would not result in any new significant or substantially more severe environmental impacts that
would affect the less-than-significant impact determination in the 2020 MND.
VMT Analysis
According to the 2020 MND, the Approved Project would result in a substantial reduction in daily
trips compared to the existing use at the time. Accordingly, the 2020 MND determined that the
Approved Project’s impact on citywide and regional VMT would be less than significant.
With regard to the Revised Project, the City of Arcadia Transportation Study Guidelines for
Vehicle Miles Traveled and Level of Service Assessment identifies Assisted Living Facilities as
one of the types of land uses under the VMT Project Type Screening criteria. Land uses of this
type are presumed to result in a less-than-significant transportation impact under CEQA and do
not require a detailed quantitative VMT assessment. Accordingly, the Revised Project would not
conflict with CEQA Guidelines Section 15064.3(b), and impacts would be considered less than
significant. Therefore, there are no material changes in circumstances, and the Revised Project
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 42
would not result in any new significant or substantially more severe environmental impacts that
would affect the less-than-significant impact determination in the 2020 MND.
Hazards Due to a Geometric Design Feature
According to the 2020 MND, the Approved Project would not create uses that could generate an
incompatible use of area roadways, which could impair circulation or safety on area roads. In
addition, no internal street network was proposed as part of the Approved Project, and, therefore,
no potential hazards associated with a geometric design feature, such as a sharp curve, would
occur within the Project Site. The Approved Project proposed a single entrance and exit driveway
onto Colorado Boulevard, which would be designed to meet the mandatory design standards of
the City of Arcadia as it relates to width, intersection control, and sight distance. Accordingly, the
2020 MND determined that through compliance with applicable City requirements related to
roadway safety, the Approved Project would not increase hazards due to a geometric design
feature or incompatible uses, and impacts would be less than significant.
The Revised Project proposes the same land use type as the Approved Project and, as such,
would not create any uses that could impair circulation or safety on area roads. As with the
Approved Project, no internal street network is proposed as part of the Revised Project, and,
therefore, no potential hazards associated with a geometric design feature, such as a sharp curve,
would occur within the Project Site. The Revised Project would retain the two existing driveways,
which would be reconstructed in the same general location, to provide site access along Colorado
Boulevard and Michillinda Avenue; the design of these driveways would be reviewed to confirm
that the reconstruction meets the mandatory design standards of the City of Arcadia as they relate
to width, intersection control, and sight distance. Accordingly, as with the Approved Project,
through compliance with applicable City requirements related to roadway safety, the Revised
Project would not increase hazards due to a geometric design feature or incompatible uses, and
impacts would be less than significant. Therefore, there are no material changes in
circumstances, and the Revised Project would not result in any new significant or substantially
more severe environmental impacts that would affect the less-than-significant impact
determination in the 2020 MND.
Emergency Access
According to the 2020 MND, the Approved Project’s building plans and structures would be
reviewed by the Arcadia Fire Department for compliance with applicable safety and emergency
access standards, including the adequacy of fire flow, access, and fire hydrant placement. In
addition, because the Project Site is located in an urban setting, where the surrounding street
network allows for access to the Project Site from multiple directions and because the Approved
Project would be designed to accommodate emergency response vehicles, the 2020 MND
determined that the Approved Project’s impacts related to emergency access would be less than
significant.
As with the Approved Project, the Revised Project’s building plans and structures would be
reviewed by the Arcadia Fire Department for compliance with applicable safety and emergency
access standards, including the adequacy of fire flow, access, and fire hydrant placement.
Similarly, because it is confined to the same Project Site, the Revised Project’s impacts related
to emergency access would be less than significant. Therefore, there are no material changes in
circumstances, and the Revised Project would not result in any new significant or substantially
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 43
more severe environmental impacts that would affect the less-than-significant impact
determination in the 2020 MND.
5.18 TRIBAL CULTURAL RESOURCES
According to the 2020 MND, no documented historic or prehistoric cultural resources were
identified on the Project Site or within a quarter-mile radius of the Project Site. As such, the 2020
MND determined that the Approved Project would not cause an adverse change in the
significance of a tribal cultural resource, defined in Public Resources Code (PRC) Section 21074
as either a site, feature, place, cultural landscape that is geographically defined in terms of the
size and scope of the landscape, sacred place, or object with cultural value to a California Native
American tribe, and that is listed or eligible for listing in the California Register or in a local register
of historical resources, and no impact would occur.
With regard to the impact related to the significance of a resource to a California Native American
tribe, the City formally consulted with the Gabrieleño Band of Mission Indians–Kizh Nation.
However, the information obtained during consultation did not demonstrate that existing tribal
cultural resources are present within the Project Site. Accordingly, the 2020 MND determined
that, due to the lack of substantial evidence as to why the Project area should be considered
sensitive for tribal cultural resources, impacts related to tribal cultural resources would be less-
than-significant. However, the 2020 MND included the following voluntary mitigation measures
imposed by the City to address the inadvertent discovery of tribal cultural resources:
TCR-1 Retail a Native American Monitor/Consultant. The Project Applicant shall be
required to retain and compensate for the services of a tribal monitor/consultant, who
is both approved by the Gabrieleño Band of Mission Indians-Kizh Nation Tribal
Government and listed under the Native American Heritage Commission’s (NAHC)
Tribal Contact list for the area of the project location. This list is provided by the
NAHC. The monitor/consultant shall only be present on-site during the construction
phases that involve ground disturbing activities. Ground disturbing activities are
defined by the Gabrieleño Band of Mission Indians-Kizh Nation as activities that may
include, but are not limited to, pavement removal, pot-holing or auguring, grubbing,
tree removals, boring, grading, excavation, drilling, and trenching, within the Project
area. The tribal Monitor/consultant shall complete daily monitoring logs that will
provide descriptions of the day’s activities, including construction activities,
locations, soil, and any cultural materials identified. The on-site monitoring shall end
when the Project Site grading and excavation activities are completed or when the
tribal representatives and monitor/consultant have indicated that the site has a low
potential for impacting tribal cultural resources.
TCR-2 Unanticipated Discovery of Tribal Cultural and Archaeological Resources.
Upon discovery of any tribal cultural or archaeological resources, construction
activities shall cease in the immediate vicinity of the find until the find can be
assessed. All tribal cultural and archaeological resources unearthed by Project
construction activities shall be evaluated by the qualified archaeologist and tribal
monitor/consultant approved by the Gabrieleño Band of Mission Indians-Kizh Nation.
If the resources are Native American in origin, the Gabrieleño Band of Mission
Indians-Kizh Nation shall coordinate with the landowner regarding treatment and
curation of these resources. Typically, the tribe will request preservation in place or
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 44
recovery for educational purposes. Work may continue on other parts of the Project
Site while evaluation and, if necessary, additional protective mitigation takes place
(CEQA Guidelines Section15064.5 [f]). If a resource is determined by the qualified
archaeologist to constitute a “historical resource” or “unique archaeological
resource,” time allotment and funding sufficient to allow for implementation of
avoidance measures, or appropriate mitigation, must be available. The treatment
plan established for the resources shall be in accordance with CEQA Guidelines
Section 15064.5(f) for historical resources. For unique archaeological resources,
preservation in place is the preferred manner of treatment in accordance with PRC
Section 21083.2(b). If preservation in place is not feasible, treatment may include
implementation of archaeological data recovery excavations to remove the resource
along with subsequent laboratory processing and analysis. All tribal cultural
resources shall be returned to the tribe. Any historic archaeological material that is
not Native American in origin shall be curated at a public, nonprofit institution with a
research interest in the materials, such as the Natural History Museum of Los
Angeles County or the Fowler Museum, if such an institution agrees to accept the
material. If no institution accepts the archaeological material, they shall be offered to
the tribe or a local school or historical society in the area for educational purposes.
TCR-3 Unanticipated Discovery of Human Remains and Associated Funerary
Objects. Native American human remains are defined in PRC 5097.98 (d)(1) as an
inhumation or cremation, and in any state of decomposition or skeletal
completeness. Funerary objects, called associated grave goods in PRC 5097.98,
are also to be treated according to this statute. Health and Safety Code 7050.5
dictates that any discoveries of human skeletal material shall be immediately
reported to the County Coroner and excavation halted until the coroner has
determined the nature of the remains. If the coroner recognizes the human remains
to be those of a Native American or has reason to believe that they are those of a
Native American, he or she shall contact, by telephone within 24 hours, the NAHC
and PRC 5097.98 shall be followed.
Upon discovery of human remains, the tribal and/or archaeological monitor/
consultant/consultant shall immediately divert work at minimum of 150 feet and place
an exclusion zone around the discovery location. The monitor/consultant(s) shall
then notify the tribe, the qualified lead archaeologist, and the construction manager
who will call the coroner. Work shall continue to be diverted while the coroner
determines whether the remains are human and subsequently Native American. The
discovery is to be kept confidential and secure to prevent any further disturbance. If
the finds are determined to be Native American, the coroner shall notify the NAHC
as mandated by State law, who will then appoint a Most Likely Descendent (MLD).
If the Gabrieleño Band of Mission Indians – Kizh Nation is designated MLD, the Koo-
nas-gna Burial Policy shall be implemented. To the tribe, the term “human remains”
encompasses more than human bones. In ancient, as well as, historic times, tribal
traditions included, but were not limited to, the preparation of the soil for burial, the
burial of funerary objects with the deceased, and the ceremonial burning of human
remains. The prepared soil and cremation soils are to be treated in the same manner
as bone fragments that remain intact. Associated funerary objects are objects that,
as part of the death rite or ceremony of a culture, are reasonably believed to have
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 45
been placed with individual human remains either at the time of death or later; other
items made exclusively for burial purposes or to contain human remains can also be
considered as associated funerary objects.
Prior to the continuation of ground disturbing activities, the land owner shall arrange
a designated site location within the footprint of the Project for the respectful reburial
of the human remains and/or ceremonial objects. In the case where discovered
human remains cannot be fully documented and recovered on the same day, the
remains shall be covered with muslin cloth and a steel plate that can be moved by
heavy equipment placed over the excavation opening to protect the remains. If this
type of steel plate is not available, a 24-hour guard should be posted outside of
working hours. The tribe shall make every effort to recommend diverting the Project
and keeping the remains in situ and protected. If the Project cannot be diverted, it
may be determined that burials shall be removed. The tribe shall work closely with
the qualified archaeologist to ensure that the excavation is treated carefully, ethically
and respectfully. If data recovery are approved by the tribe, documentation shall be
taken which includes at a minimum detailed descriptive notes and sketches.
Additional types of documentation shall be approved by the tribe for data recovery
purposes. Cremations shall either be removed in bulk or by means as necessary to
ensure completely recovery of all material. If the discovery of human remains
includes four or more burials, the location is considered a cemetery and a separate
treatment plan shall be created. Once complete, a final report of all activities is to be
submitted to the tribe and the NAHC. The tribe does not authorize any scientific study
or the utilization of any invasive and/or destructive diagnostics on human remains.
Each occurrence of human remains and associated funerary objects shall be stored
using opaque cloth bags. All human remains, funerary objects, sacred objects and
objects of cultural patrimony shall be removed to a secure container on site if
possible. These items shall be retained and reburied within six months of recovery.
The site of reburial/repatriation shall be on the Project Site but at a location agreed
upon between the tribe and the landowner at a site to be protected in perpetuity.
There shall be no publicity regarding any cultural materials recovered.
TCR-4 Professional Standards. Archaeological and Native American monitoring and
excavation during construction projects shall be consistent with current professional
standards. All feasible care to avoid any unnecessary disturbance, physical
modification, or separation of human remains and associated funerary objects shall
be taken. Principal personnel must meet the Secretary of Interior’s Standards for
archaeology and have a minimum of 10 years of experience as a principal
investigator working with Native American archaeological sites in Southern
California. The qualified archaeologist shall ensure that all other personnel are
appropriately trained and qualified.
As with the Approved Project, development of the Revised Project would occur within the
boundaries of the Project Site, where no tribal cultural resources have been identified. Thus,
development of the Revised Project would result in a less-than-significant impact on tribal cultural
resources. However, as with the Approved Project, the Revised Project would include Mitigation
Measures TCR-1 through TCR-4, which are voluntary mitigation measures that the City would
impose as an added protection to address the inadvertent discovery of tribal cultural resources.
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 46
Therefore, there are no material changes in circumstances, and the Revised Project would not
result in any new significant or substantially more severe environmental impacts that would affect
the less-than-significant impact determination in the 2020 MND.
5.19 UTILITIES/SERVICE SYSTEMS
Water Conveyance/Supply and Wastewater Treatment/Conveyance
According to the 2020 MND, the Approved Project would result in the daily consumption of
approximately 10,000 gallons of water and daily generation of the same amount of wastewater.
These would represent a daily net reduction of 3,088 gallons in water consumption and
wastewater generation due to the change in land use from a high turnover restaurant to an
assisted living facility. Accordingly, the 2020 MND determined that the Approved Project would
not require or result in the relocation or construction of new or expanded water or wastewater
treatment facility, the construction or relocation of which could cause significant environmental
effects, and impacts related to water consumption/water supply and wastewater generation would
be less than significant.
The Revised Project proposes the same land use type as the Approved Project. However, the
Revised Project would involve a larger development than analyzed in the 2020 MND. In addition,
because the restaurant occupying the existing building closed since the adoption of the 2020
MND, the amount of water consumed and wastewater generated by the restaurant use are no
longer applied. As a result, the Revised Project would consume approximately 14,250 gallons per
day of water and would generate the same amount of wastewater.7
Nonetheless, according to the City’s 2020 Urban Water Management Plan (UWMP), the City can
meet water demands during normal years, single dry years, and five consecutive year drought
periods through 2045.8 Because the Revised Project is consistent with the underlying zoning and
General Plan land use designation for the Project Site, the population and employment growth
associated with the Revised Project would have been incorporated into the SCAG 2020-2045
RTP/SCS growth projections, on which the City’s 2020 UWMP was based.
Furthermore, as related to wastewater, the City’s 2020 UWMP identified the three water
reclamation plants owned by the Los Angeles County Sanitation Districts of Los Angeles and
serving the City as having a combined treatment capacity of 415 million gallons per day of
wastewater. As such, the approximately 14,250 gallons per day of wastewater generated by the
Revised Project would represent 0.003 percent of the treatment capacity, which is considered a
negligible increase. The Revised Project would connect to an existing 21-inch sewer main to the
west along Michillinda Avenue via a new sewer lateral.
Accordingly, as with the Approved Project, the Revised Project would not require or result in the
relocation or construction of new or expanded water or wastewater treatment facility, the
construction or relocation of which could cause significant environmental effects, and impacts
related to water consumption/water supply and wastewater generation would be less than
significant. Therefore, there are no material changes in circumstances, and the Revised Project

Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 47
would not result in any new significant or substantially more severe environmental impacts that
would affect the less-than-significant impact determination in the 2020 MND.
Storm Drains
As discussed in Section 5.10, Hydrology and Water Quality, of this addendum, the 2020 MND
determined that the Approved Project would slightly reduce the amount of impervious surfaces
on the Project Site due to the increase in the amount of pervious landscape areas proposed by
the Approved Project as compared to existing conditions. In addition, only stormwater overflow
from the Project Site would drain to the existing private storm drain at the southeastern corner of
the Project Site. Therefore, the Approved Project would not contribute to additional runoff as
compared to existing conditions and would not result in the relocation or construction of new or
expanded storm drain facilities, the construction or relocation of which could cause significant
environmental effects. Therefore, impacts related to drainage were determined to be less than
significant.
As with the Approved Project, development of the Revised Project would not substantially change
the amount of impervious surface area on-site as compared to existing conditions. In addition, the
Revised Project would be required to comply with the same existing regulations as the Approved
Project. Furthermore, similar to the Approved Project, the Revised Project would likely have a
beneficial effect given the reduction in overall impervious surfaces as compared to existing
conditions. As such, the Revised Project would not alter the existing drainage pattern of the
Project Site that would create or contribute runoff water that would exceed the capacity of the
existing stormwater drainage system. Accordingly, as with the Approved Project, the Revised
Project would not require or result in the relocation or construction of new or expanded stormwater
drainage facilities, the construction or relocation of which could cause significant environmental
effects, and impacts related to storm drains would be less than significant. Therefore, there are
no material changes in circumstances, and the Revised Project would not result in any new
significant or substantially more severe environmental impacts that would affect the less-than-
significant impact determination in the 2020 MND.
Electricity, Natural Gas, and Telecommunications
According to the 2020 MND, the Approved Project would result in a net reduction in electricity and
natural gas consumption due to the change in land use from a high turnover restaurant to an
assisted living facility; further, the Approved Project could be served by existing
telecommunication facilities that are available in the Project area. Accordingly, the Approved
Project would not require or result in the relocation or construction of new or expanded power
lines, natural gas lines, or telecommunication facilities, the construction or relocation of which
could cause significant environmental effects. Therefore, impacts related to electricity, natural
gas, and telecommunication facilities would be less than significant.
The Revised Project proposes the same land use type as the Approved Project. However, the
Revised Project would involve a larger development than analyzed in the 2020 MND. In addition,
because the restaurant occupying the existing building closed since the adoption of the 2020
MND, the amount of electricity and natural gas consumed by the restaurant use is no longer
applied. As a result, the Revised Project would result in higher consumption of electricity and natural
gas than the Approved Project. Nonetheless, as discussed in Section 5.6, Energy, of this
addendum, the Revised Project’s electricity and natural gas usage would constitute a nominal
increase compared to the County’s annual electricity and natural gas consumption. As with the
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 48
Approved Project, the Revised Project could be served by existing telecommunication facilities
that are available in the Project area. Accordingly, as with the Project, the Revised Project would
not require or result in the relocation or construction of new or expanded power lines, natural gas
lines, or telecommunication facilities, the construction or relocation of which could cause
significant environmental effects. As such, impacts related to electricity, natural gas, and
telecommunication facilities would be less than significant. Therefore, there are no material
changes in circumstances, and the Revised Project would not result in any new significant or
substantially more severe environmental impacts that would affect the less-than-significant impact
determination in the 2020 MND.
Solid Waste
According to the 2020 MND, the Approved Project would result in the daily generation of
approximately 400 pounds of solid waste, a daily net reduction of 9 pounds due to the change in
land use from a high turnover restaurant to an assisted living facility. Accordingly, the 2020 MND
determined that the Approved Project would not generate solid waste in excess of State or local
standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment
of solid waste reduction goals and that impacts would be less than significant.
The Revised Project proposes the same land use type as the Approved Project. However, the
Revised Project would involve a larger development than analyzed in the 2020 MND. In addition,
because the restaurant occupying the existing building closed since the adoption of the 2020
MND, the amount of solid waste generated by the restaurant use is no longer applied. As a result,
the Revised Project would generate approximately 570 pounds per day of solid waste.9 This would
represent a daily net increase of 170 pounds of solid waste when compared to the Approved
Project. However, according to the 2020 MND, the City’s General Plan Update Program
Environmental Impact Report determined that there would be no significant adverse impact on
landfill capacity and that continuation of existing City and County programs and implementation
of pertinent goals, policies, and implementation actions in the General Plan Update would provide
for future developments’ compliance with solid waste regulations.10 Accordingly, as with the
Approved Project, the Revised Project would not generate solid waste in excess of State or local
standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment
of solid waste reduction goals, and impacts would be less than significant. Therefore, there are
no material changes in circumstances, and the Revised Project would not result in any new
significant or substantially more severe environmental impacts that would affect the less-than-
significant impact determination in the 2020 MND.
5.20 WILDFIRE
According to the 2020 MND, the Project Site is not located within or adjacent to a state
responsibility area or a Very High Fire Hazard Severity Zone (VHFHSZ), as designated by the
California Department of Forestry and Fire Protection. Accordingly, the 2020 MND determined
that the Approved Project would not (1) substantially impair an adopted emergency response plan
or emergency evacuation plan, (2) exacerbate wildfire risks and expose the residents of the
Approved Project to pollutant concentrations from a wildfire or the uncontrolled spread of a
wildfire, (3) require the installation or maintenance of associated infrastructure (such as roads,
fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk
9 Based on the solid waste generation rate of 5 pounds per day per person used in the 2020 MND.

City of Arcadia Page 49
or that may result in temporary or ongoing impacts to the environment, or (4) expose people or
structures to significant risks, including downslope or downstream flooding or landslides, as a
result of runoff, post-fire slope instability, or drainage changes. No impact related to wildfire would
occur.
As with the Approved Project, development of the Revised Project would occur within the
boundaries of the Project Site, which is not located within or adjacent to a state responsibility area
or a VHFHSZ. Accordingly, as with the Approved Project, development of the Revised Project
would have no impact related to wildfire. Therefore, there are no material changes in
circumstances, and the Revised Project would not result in any new significant or substantially
more severe environmental impacts that would affect the no-impact determination in the 2020
MND.
5.21 MANDATORY FINDINGS OF SIGNIFICANCE
The 2020 MND determined that, with implementation of the identified mitigation measures related
to biological resources, archaeological resources, paleontological resources, noise, and tribal
cultural resources, the Approved Project would not degrade the quality of the environment.
Specifically, the Approved Project would not have substantial impacts to special-status species,
stream habitat, and wildlife dispersal. Mitigation Measure BIO-1 would ensure that tree removal
would not pose a significant impact to migratory wildlife species. Furthermore, the Approved
Project would not affect the local, regional, or national populations or ranges of any plant or animal
species and would not threaten any plant communities. Similarly, with implementation of
Mitigation Measures CUL-1, GEO-1, and TCR-1 through TCR-4, the Approved Project would
not have substantial impacts to historical, archaeological, paleontological, or tribal cultural
resources and, thus, would not eliminate any important examples of California history or
prehistory. Therefore, the Approved Project would not result in a Mandatory Finding of
Significance due to impacts to biological, cultural, paleontological, or tribal cultural resources.
In addition, the 2020 MND determined that the Approved Project would not have the potential to
cause impacts that are cumulatively considerable as the Approved Project would not result in any
significant and unavoidable impacts in any environmental categories. In all cases, the impacts
associated with the Approved Project would be limited to the Project Site and were of such a
negligible degree that they would not result in a significant contribution to any cumulative impacts.
In some cases, the Approved Project would result in a net reduction when compared to existing
conditions (i.e., related to emissions, transportation, water consumption, and wastewater and
solid waste generation). Therefore, the Approved Project would not result in a Mandatory Finding
of Significance due to cumulative impacts.
Furthermore, the Approved Project would not have the potential to result in direct or indirect
substantial adverse effects on human beings. Although construction noise is allowed during the
City’s allowable construction hours and is not considered to be a significant impact during those
hours, the Approved Project could expose adjoining residential uses to temporary high noise
levels during construction activities. Accordingly, Mitigation Measure NOI-1 was recommended
to reduce short-term construction noise impacts through noise reduction methods to a less-than-
significant level. In all other environmental issue areas, the Approved Project would not approach
or exceed any significance thresholds typically associated with direct or indirect effects on people,
such as air, water, or land pollution, natural environmental hazards, transportation-related
hazards, or adverse effects to emergency service response. Therefore, the Approved Project
Addendum to the Artis Senior Living Project IS/MND April 2024
City of Arcadia Page 50
would not result in a Mandatory Finding of Significance due to direct or indirect effects on human
beings.
As with the Approved Project, the Revised Project would be required to comply with all mitigation
measures identified in the 2020 MND. Furthermore, there are no design features included within
the Revised Project that would suggest that these mitigation measures would not be sufficient to
address any potentially significant impact that would arise from implementation of the Revised
Project. As such, there are no material changes in circumstances, and implementation of the
Revised Project would not result in any new significant or substantially more severe environmental
impacts that would affect the determination of less-than-significant impact and less-than-
significant impact with mitigation in the 2020 MND.
6.0 CONCLUSION
CEQA Guidelines Section 15164(b) states that the Lead Agency shall prepare an addendum to a
previously certified negative declaration if only minor technical changes or additions are
necessary or none of the conditions described in CEQA Guidelines Section 15162 calling for the
preparation of a subsequent negative declaration have occurred. The Revised Project described
above does not result in significant modifications or have any occurrences within the conditions
described in CEQA Guidelines Section 15162. In addition, the impact comparison provided above
demonstrates that no new potentially significant impacts would occur and that no substantial
increase in the severity of impacts would occur upon implementation of the Revised Project.
On the basis of the evaluation contained in this document, there are no changes in the Approved
Project or the circumstances under which the Revised Project is being undertaken or any new
information of substantial importance that was not known to the Lead Agency at the time the 2020
MND was adopted that trigger any of the conditions identified in CEQA Guidelines Section 15162,
which would require a subsequent CEQA document. Therefore, pursuant to CEQA Guidelines
Sections 15162 and 15164, this addendum has been prepared to document the changes to the
adopted 2020 MND for the Revised Project to explain the Lead Agency’s decision not to prepare
a subsequent CEQA document or a new MND.

6. Climate Risk Detailed Report
6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG
emissions will continue to rise strongly through 2050 and then plateau around 2100.
Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 20.8 annual days of extreme heat
Extreme Precipitation 7.85 annual days with precipitation above 20 mm
Sea Level Rise — meters of inundation depth
Wildfire 6.20 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed
historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full
day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider
inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events.
Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters
Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate,
vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make
different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature
possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

TECHNICAL MEMORANDUM
To: Edwin Arreola, City of Arcadia
From: Carla Dietrich, Michael Baker International
CC: Madonna Marcelo, Michael Baker International
Date: March 21, 2024
Subject: Addendum to the Artis Senior Assisted Living Project Trip Generation Analysis
Project Background
On August 18, 2020, the City of Arcadia City Council adopted a Mitigated Negative Declaration for the Artis Senior Living
Project, which was proposed at the southeastern corner of the intersection of Colorado Boulevard and Michillinda
Avenue at 1150 West Colorado Boulevard in the City of Arcadia. The Artis Senior Living Project involved the demolition
of an approximately 13,000-square-foot building (previously occupied by a Coco’s Bakery and Restaurant) and the
development of a new two-story, 44,192-square-foot senior/assisted living care facility with 80 rooms and on-site
amenities (Approved Project). The Project Applicant, O&I Development, LLC, is now proposing to develop the Project
site with a new 107,706-square-foot, three-story building which would have the same use as the Approved Project and
constitute the Revised Project. In considering whether to approve the Revised Project, the City, as the lead agency
pursuant to the California Environmental Quality Act (CEQA), is required to consider the environmental consequences
of the Revised Project as compared to those of the Approved Project. Therefore, this addendum assesses the trip
generation analysis of the Revised Project as compared to the Approved Project using the same analysis process of
evaluating the Project trip generation using the Institute of Transportation Engineer’s (ITE) Trip Generation Manual, 10th
Edition.
Project Description
The Revised Project proposes the construction of a 107,706 square-foot building with 100 units of varying size including
studio, one-bedroom, and two-bedroom units for assisted living and private and shared studios for memory care. The
100 units are proposed to accommodate 114 beds. As with the Approved Project, the Revised Project would support
assisted living and memory care services, the latter of which would entirely be dedicated to people afflicted with
Alzheimer’s disease and related memory disorders. Exhibit A-1 (attached) shows the proposed site plan.
Previous Approved Project Finding
The Approved Project trip generation analysis determined a minimal change in the number of site trips entering and
exiting the site at the W. Colorado Boulevard driveway. It was anticipated that these minimal changes in site trips would
have had a negligible impact on site driveway and nearby intersection operations. It should be noted that the Coco’s
Bakery and Restaurant was operational when the Approved Project trip generation analysis was initiated and thus an
existing trip credit was applied as part of that analysis.

Revised Project Trip Generation
Applicable Trip Credits
Trip credits may be applied to account for certain conditions including current operational uses located at the proposed
site. Table 1 details the type of trip credits which were considered during this study.

Trip generation analysis was conducted for the weekday daily, AM Peak Hour, and PM Peak Hour time periods. The ITE
Trip Generation Manual, 10th Edition published in 2017, was the source of the project trip generation rates, as was the
case for the Approved Project analysis. Table 2 summarizes the trip generation rates for the Assisted Living use (Land
Use Code 254). It should be noted that the planned Project includes amenities for residents including a beauty salon, a
fitness facility, and a restaurant. These uses are ancillary to the care facility and will be available for use by the residents
rather than for commercial purposes or outside users. Ancillary uses are accounted for in the Land Use Code 254 trip
generation rates.

Trip Distribution/Assignment
The Revised Project facility will have two access points (see Exhibit 1). One driveway will provide full access along W.
Colorado Boulevard and the second driveway will provide right-in/right-out access along Michillinda Avenue. While the
Approved Project only had one site driveway which was located on W. Colorado Boulevard, the driveway locations for
the Revised Project are consistent with the two existing Coco’s Bakery and Restaurant driveways.Exhibit 2 graphically
shows the anticipated distribution patterns for the proposed Assisted Living facility with two driveways and Exhibit 3
shows the anticipated site trips for the Revised Project at each of the site driveways.

Exhibit 3: Revised Project Site Trip Assignment
Table 3 summarizes the total site trips at each of the site driveways. Here are the key findings:
x Revised Project – It is anticipated that the Revised Project will add no more than 16 site trips to each of the
two site driveways during each of the peak hours.
x Comparison of the Revised Project to the Approved Project – A comparison of site trips between the Revised
Project to the Approved Project indicates that the Revised Project will add 17 or fewer site trips to each of the
site driveways during each of the peak hours. It should be noted that the Approved Project site trips were
adjusted by applying a trip credit for the Coco’s Bakery and Restauranttrips. Since the restaurant closed between
the time of the original evaluation of the Approved Project and this evaluation of the Revised Project, the Coco’s
Bakery and Restaurant trip credit was no longer applied to provide a conservative estimate.If the trip credit had
been accounted for in this analysis of the Revised Project, the additional site trips added under the Revised
Project would be even fewer.

Additional Trip Generation Analysis
As noted above, the analysis utilized trip rates from the ITE Trip Generation Manual, 10th Edition published in 2017. This
was the source of the project trip generation rates for the Approved Project analysis. An updated Trip Generation Manual
(11th Edition) was published after the Approved Project analysis was completed. While the use of the 10th Edition is
appropriate for the comparison to the Approved Project since it was the previously approved method, an additional
comparison was conducted using the 11th Edition. Table 4 provides the trip rates and Table 5 provides the estimated
trips for both editions of the manual. As shown, the daily, AM Peak Hour, and PM Peak Hour rates included 11th Edition
of the manual are the same or lower than the 10th Edition rates. Therefore, the difference in the estimated Project trips
using both editions of the manual are negligible.

Findings
It is estimated that the Revised Project will add no more than 16 new peak hour site trips to each of the site driveways
during each of the peak hours. A comparison between the Approved Project and the Revised Project again shows a
minimal increase in traffic due to the Revised Project (no more than 17 peak hour trips at each of the site driveways).
These additional trips are equivalent to an average of no more than 1 trip every 3½ minutes. It is anticipated that these
minimal changes in site trips would have a negligible impact on the area intersections. Additionally, if the Coco’s Bakery
and Restaurant trip credit had been taken in this analysis of the Revised Project, the additional site trips added under
the Revised Project would be even fewer.
The trip comparison utilized the 10th Edition of the ITE Trip Generation Manual to be consistent with the Approved
Project. An additional comparison was conducted using the 11 th Edition of the Trip Generation Manual which was
published after the Approved Project analysis was conducted. The daily, AM Peak Hour, and PM Peak Hour rates included
6 | Page
11th Edition of the manual for the Assisted Living use are the same or lower than the 10th Edition rates. Therefore, the
difference in the estimated Project trips using both editions of the manual are negligible.
Additionally, after the Approved Project trip generation technical memorandum, the City-adopted the City of Arcadia
Transportation Study Guidelines for Vehicle Miles Traveled and Level of Service Assessment (August 2020). The guidance
in that document states that a Traffic Study with Level of Service analysis shall be required for a proposed project when
either the AM or PM peak hour trip generation for the proposed development is expected to exceed 100 vehicle trips
and for projects that will add 51 or more trips during either the AM or PM peak hour to any intersection. While these
guidelines were not adopted at the time of the original analysis, it is interesting to note that the Revised Project generates
only a small fraction of the current trip thresholds requiring a Level of Service Traffic Study.
Also, after the Project was analyzed, the CEQA transportation metric changed from Level of Service to Vehicle Miles
Traveled (VMT). While VMT is not required in this analysis, it should be noted that the City of Arcadia Transportation
Study Guidelines for Vehicle Miles Traveled and Level of Service Assessment (August 2020) identifies Assisted Living
Facilities as one of the types of land uses under the VMT Project Type Screening criteria. Land uses of this type can be
presumed to have a less-than-significant impact absent substantial evidence to the contrary based on those guidelines.

8. Description of Project:
Existing Conditions
The proposed Project Site is designated in the City’s General Plan as Commercial with a
corresponding zoning of C-G, General Commercial. The C-G Zone is intended to provide
areas for the development of retail, offices, restaurants, and service uses. The Project Site is
included within two municipal overlay zones, the Architectural Design Overlay Zone and the
Automobile Parking Overlay Zone. As shown in Figure A-3, Project Site Overlay Zones ,
these overlay zones are limited to the Project Site, with the Architectural Design Overlay Zone
covering the central and northwestern portion of the Project Site and the Automobile Parking
Overlay Zone covering the southern and eastern portions of the Project Site. The
Architectural Design Overlay Zone states that various building design characteristics (such as
building exterior materials, roof pitch, window size, landscaping, and automobile parking area)
shall be subject to Planning Commission review and approval. Further, the Architectural
Design Overlay Zone states that only one free-standing sign shall be permitted and located
within 100 feet of the northern and western property lines, the maximum building height shall
Artis Senior Housing Project
Draft Initial Study Page 2 April 2020
not reach 30 feet above ground level, and no structure erected or permitted shall exceed 19,500
square feet of ground floor area.1,2 The Automobile Parking Overlay Zone restricts the overlay
area to ground level parking uses
The Project Site consists of 2.79 acres of developed land in the northwestern portion of the
City of Arcadia. The Project Site is located on the southeastern corner of the Colorado
Boulevard and Michillinda Avenue intersection, immediately south of Interstate 210 (I-210/
Foothill Freeway).
The Project Site contains an existing Coco’s Bakery and Restaurant, which was constructed in
1976. The existing Coco’s, which comprises 13,088 square feet in total floor area, is a
rectangular, one-story building located in the center of the Project Site. The building is
surrounded on all sides by a surface parking lot, with two driveway locations, one at the
northeastern corner of the Project Site along Colorado Boulevard and another at the
southwestern corner of the Project Site along Michillinda Avenue. Mature eucalyptus trees
flank the western and eastern sides of the Coco’s building. Additionally, there are decorative
shrubs and turf along the northern, eastern, and western façades of the building, with one
mature fern pine near the northeastern corner of the building. Currently, there is a mix of trees
along the perimeter of the Project Site, serving as a landscape buffer between the Project Site
and neighboring streets to the north and west and the residential neighborhoods to the east
and south. The parking lot contains pole-mounted security lights, concrete bollards with
chains that divide the parking lot on the south side of the lot, and landscape islands with
decorative shrubs. Architectural lighting is also mounted along the edge of the roof of the
northern façade and on the four corners of the roof of the Coco’s building and is directed
inwardly. This roof-mounted lighting illuminates the Coco’s sign mounted above the building
entrance on the north elevation and creates visual interest by illuminating the gently pitched
roof line. Photos of the Project Site’s existing conditions are shown in Figures A-4 through
A-8.
The Colorado Boulevard and Michillinda Avenue frontages are both improved with a
sidewalk, curb, gutter, and three streetlights each, with a sidewalk parkway comprising a strip
of turf grass. Each frontage is characterized by decorative ground cover; mature trees; a short,
white-painted cinderblock wall; and decorative shrubs located between the sidewalk and the
property line. A block and wood sign for Coco’s (and The Oak Tree Room inside Coco’s) is
located at the northwestern corner of the Project Site.
Project Characteristics
To accommodate the Proposed Project, the Coco’s building would be demolished, and
associated landscaping and surface parking lot would be removed. However, the majority of
the trees along the perimeter of the Project Site would be retained and incorporated into the
Proposed Project’s landscaping plan. As shown in Figure A-9, Proposed Site Plan, the
Proposed Project would develop a W-shaped senior living facility, which would support
memory care and assisted living services that would entirely be dedicated to people afflicted
with Alzheimer’s disease and related memory disorders. The facility would comprise a new
two-story 44,192-square-foot building with 80 senior housing units; each unit, which would

Artis Senior Housing Project
Draft Initial Study Page 3 April 2020
range in size generally between 216 square feet and 302 square feet, would primarily consist
of a bed and a private bathroom with a shower.
The first floor of the proposed building would contain 40 senior housing units, a lobby, offices,
resident dining rooms, storage, and several large and small activities rooms and common
spaces within 23,767 square feet of floor area, while the second floor of the proposed building
would contain 40 units of senior housing, as well as dining rooms and activities room and
common space, within 20,425 square feet of floor area. The Proposed Project would also
include decorative landscaping, private walking paths, and an outdoor plaza on the west and
south sides of the Project Site. The proposed building would extend to 37.5 feet in height.
As shown in Figures A-10 and A-11, the proposed structure would feature a
traditional/Craftsman-style design with varied massing and materials with articulation on each
of the building façades to increase visual interest and avoid flat, street-facing surfaces. The
moderately pitched roof would be made of black walnut-colored asphalt shingles and would
contain recessed, flat centers, which would screen mechanical equipment, such as heating and
air conditioning equipment and exhaust fans, from view from the street. The elevations would
feature windows with exterior shutters alongside brick and alternating vertical and horizontal
cement fiber board siding. The design would include decorative features, such as trellises on
the north, east, and west elevations, as well as columns and decorative railing at the front and
rear entrances. An 8-foot-high wooden fence, with a decorative wooden topper, would enclose
the southern portion of the Project Site, which would include a gazebo, lawn, outdoor plaza,
and walking paths described above. This fence would connect to the northwestern and
northeastern corners of the building and extend to the southern property line. There is one
gate with a Knox Box that connects the walkways within the fenced enclosure to the parking
area on the east side of the Project Site. Two gated pathways with Knox Boxes would connect
the enclosed walking paths to Michillinda Avenue on the west side of the Project Site. The
majority of the building would extend to approximately 30 feet in height, with the front
entrance, located in the center of the building, extending to 37.5 feet in height. The building
would be topped with a small, decorative cupola, which would extend to approximately 40
feet, 10 inches in height. A conceptual rendering of the Proposed Project is displayed in
Figure A-12.
The Proposed Project would include multiple new sources of light, including pole-mounted
LED security lighting in parking areas and the passenger drop-off area; path lighting on
internal walkways; accent lighting over building doorways; and a lighted sign located on the
northwest corner of the Project Site.
Vehicle parking would include 55 regular parking stalls and 4 parking stalls that comply with
the requirements of the Americans with Disabilities Act (ADA). Vehicular access to the
proposed building would be from a single ingress/egress point on Colorado Boulevard,
located at an existing ingress/egress point for the Project Site. A circular drive in front of the
proposed building’s entrance would accommodate passenger loading and unloading. A
separate loading dock for materials and food deliveries would be located near the Project Site’s
driveway at the northeastern corner of the proposed building. Directly north of the loading
space would be the trash enclosure and an emergency generator for the senior care facility.
The exterior finishes and materials of the enclosures would match the senior care facility. The
Artis Senior Housing Project
Draft Initial Study Page 4 April 2020
enclosure to the trash area and emergency generator would stand between 8 and 12 feet in
height.
The majority of trees along the perimeter of the Project Site would be preserved in place to
continue to form a vegetative screen between the Project Site and the residential uses to the
east and south. The proposed building would be surrounded by landscaping, including
drought-tolerant shrubs and ground cover, flower gardens, decorative trees, a lawn
area/outdoor plaza with a gazebo, and a meandering concrete walkway with connections
through locked gates to the existing sidewalks on Michillinda Avenue and Colorado Boulevard.
The existing curb, gutter, and sidewalks along the Project Site’s Colorado Boulevard and
Michillinda Avenue frontages would be replaced as part of the Proposed Project. The public
right-of-way along the Project Site’s Colorado Boulevard frontage would be widened to 12
feet in width, which would require a four-foot dedication from the Project Site, as shown in
Figure A-9. Additional decorative trees would be planted in the parking area to provide shade
and additional screening from adjacent uses. A detailed landscape plan is available as
Figure A-13, Proposed Landscape Plan.
The Proposed Project would require the following City approvals:
x Adoption of the IS/MND
x Zone Change: To revoke the existing Architectural Design (D) Overlay Zone and
Automobile Parking (P) Overlay Zone from the Project Site;
x Architectural Design Review Approval;
x Conditional Use Permit to allow for the development of the Proposed Project in a C-
G Zone;
x Tree Encroachment Permit; and
x Minor Administrative Modification for the request to exceed the maximum permitted
fence height of 6 feet.
9. Surrounding Land Uses and Setting:
The Project Site is located in a fully urbanized part of the City of Arcadia, where the built
environment consists of a mixture of single-family residential and commercial uses to the east
in the City of Pasadena, and I-210 to the north, across the street from the Project Site.
Colorado Avenue is a four-lane, east-west running roadway with a center turn lane, classified
as a Secondary Travel Corridor by the Arcadia General Plan Circulation and Infrastructure
Element. Michillinda Avenue is a four-lane, north-south running roadway that forms the
western boundary of the City of Arcadia. Land uses west of Michillinda Avenue are located in
East Pasadena, a neighborhood in unincorporated Los Angeles County.
Figure A-14, Aerial View of the Project Site and Surroundings, provides a view of the
local land use pattern in the vicinity of the Project Site. These surrounding land uses include
one-level, detached, single-family homes to the east and south, which were generally
constructed between the 1930s and 1970s; a gasoline station with a convenience store and a
single-family home across Michillinda Avenue to the west; an approximately 40-foot-high
Artis Senior Housing Project
Draft Initial Study Page 5 April 2020
commercial building to the northwest; and mature trees and I-210 across Colorado Boulevard
to the north.
10. Other Public Agencies Whose Approval is Required:
x California Department of Social Services (DSS)
x Division of the State Architect
11. Have California Native American tribes traditionally and culturally affiliated with the project
area requested consultation pursuant to Public Resources Code section 21080.3.1? If so, is
there a plan for consultation that includes, for example, the determination of significance of
impacts to tribal cultural resources, procedures regarding confidentiality, etc.?3
Yes. The City sent notification letters to the Gabrielino-Tongva Tribe and the Gabrieleño
Band of Mission Indians—Kizh Nation on January 10, 2020. On January 23, 2020, Andrew
Salas, of the Gabrieleño Band of Mission Indians – Kizh Nation submitted a formal request
to consult with the City. The tribal consultation process commenced on April 1, 2020 via a
conference call attended by Andrew Salas and Matt Teutimez of the Gabrileño Band of
Mission Indians, Lisa Flores and Vanessa Quiroz of the City of Arcadia, and Madonna Marcelo
and John Bellas of Michael Baker International (the City’s environmental consultant). Please
refer to Section XVIII, Tribal Cultural Resources, of this Initial Study for a discussion of the
results of the consultation.
3 NOTE: Conducting consultation early in the CEQA process allows tribal governments, lead agencies, and project
proponents to discuss the level of environmental review, identify and address potential adverse impacts to tribal
cultural resources, and reduce the potential for delay and conflict in the environmental review process. (See Public
Resources Code section 21080.3.2.) Information may also be available from the California Native American Heritage
Commission’s Sacred Lands File per Public Resources Code section 5097.96 and the California Historical Resources
Information System administered by the California Office of Historic Preservation. Please also note that Public
Resources Code section 21082.3(c) contains provisions specific to confidentiality.

answer is provided according to the analysis undertaken as part of the Initial Study. The analysis
considers the long-term, direct, indirect, and cumulative impacts of the project. To each question,
there are four possible responses:
No Impact. The project would not have any measurable environmental impact on the
environment.
Less Than Significant Impact. The project would have the potential for impacting the
environment, although this impact would be below established thresholds that are considered
to be significant.
Less Than Significant Impact With Measures Incorporated . The project would have the
potential to generate impacts which may be considered a significant effect on the environment,
although measures or changes to the development’s physical or operational characteristics can
reduce these impacts to levels that are less than significant.
Potentially Significant Impact. The project would have impacts which are considered
significant, and additional analysis is required to identify measures that could reduce these
impacts to less than significant levels.

Discussion
The Proposed Project is not classified as a “transit-oriented infill project” as set forth in Section 21099
of the Public Resources Code (PRC), and, thus, the provisions of that section do not apply to this
Project.
a) Would the project have a substantial adverse effect on a scenic vista?
Less Than Significant Impact. A scenic vista is defined as a publicly accessible, prominent vantage
point that provides expansive views of highly valued landscapes or prominent visual elements
composed of man-made or natural features. Michillinda Avenue and North Altura Road, which both
provide views of the San Gabriel Mountains for northbound travelers, could be considered public
vantage points that provide a view of a highly valued landscape (i.e., the San Gabriel Mountains);
however, the mountain views are distant, not expansive, and are extensively obstructed by existing
development, utilities, and landscaping. Further, because the majority of the City is relatively flat,
including the area surrounding the Project Site, the City of Arcadia General Plan does not identify any
prominent vantage points from which the public can view an expansive scenic vista within or beyond
the City.4,5
As discussed in the Project Description of this Initial Study, the Project Site is located in a highly
urbanized area, dominated by features of a built environment. The surrounding development includes
a mixture of building sizes, styles, and forms, and includes single-family residential, low- and mid-rise
commercial, and freeway infrastructure. Many of the main arterial roadways in the City of Arcadia that

are oriented north and south provide views of the San Gabriel Mountains in the distance. As such,
motorists traveling northbound on Michillinda Avenue (along the western boundary of the Project
Site) and North Altura Road (one block east of the Project Site) have distant views of the San Gabriel
Mountains, which begin approximately 1.9 miles north of the Project Site. Views of the mountains are
partially obstructed by mature trees and existing development along both of these streets, I-210, and
the overpass over Michillinda Avenue, as well as utility poles, traffic signals, and business signs on
either side of Michillinda Avenue. As a result of these existing impediments, views of the San Gabriel
Mountains are only available straight north and are obstructed to the northeast and northwest. In
addition, because the proposed senior housing building would be set back approximately 106 feet
from the Project Site’s eastern boundary and set back approximately 52 feet from Michillinda Avenue,
the proposed building would not substantially impact the existing, limited mountain views available to
motorists. Further, the existing restaurant building is approximately 20 feet in height and is surrounded
by mature eucalyptus trees that extend to approximately 60 feet high. The majority of the Proposed
Project would extend to approximately 30 feet in height, with the front entrance, located in the center
of the building, extending to 37.5 feet in height (see Figures A-10 and A-11, which illustrate the
Proposed Project’s building elevations and indicate building heights). The building would be topped
with a small, decorative cupola, which would extend to approximately 40 feet, 10 inches in height. The
existing eucalyptus trees on the Project Site are visible from North Altura Road, looking west over the
existing single-family homes. The Proposed Project may also be visible from North Altura Road
looking west over the existing single-family homes; however, the Proposed Project would not obstruct
any existing views of the San Gabriel Mountains to the north from North Altura Road. Therefore,
effects of the Proposed Project on scenic vistas would be less than significant.
b) Would the project substantially damage scenic resources, including, but not limited to,
trees, rock outcroppings, and historic buildings within a state scenic highway?
Less Than Significant Impact. The closest officially designated State scenic highway to the Project
Site is part of the Angeles Crest State Scenic Highway, State Route 2 (SR-2), from near La Cañada-
Flintridge north to the San Bernardino County line. This State scenic highway is approximately 8.5
miles northwest of the Project Site. The Arroyo Seco Historic Parkway (SR-110), between mileposts
25.7 and 31.9 in Los Angeles, is approximately 5 miles west of the Project Site. The distance between
the Project Site and these officially designated scenic highways indicates that the Proposed Project
would not be visible from a State scenic highway. Finally, I-210 north of SR-134 is designated as an
eligible scenic highway; however, since the Project Site is approximately 5 miles west of this eligible
scenic highway, the Proposed Project would not be visible from this viewshed. As such, the Proposed
Project would not adversely affect the viewshed from a State scenic highway.
There are a number of scenic resources on the Project Site. Although there are no rock outcroppings
or historic buildings on the Project Site, the Project Site’s mature trees could be considered scenic
resources because the City’s General Plan states that “Arcadia’s trees are a significant aesthetic and
ecological resource” and are “one of the City’s real treasures,” distinguishing Arcadia from other cities
in the vicinity.6 Specifically, mature trees of various species are located around the perimeter of the
Project Site, nearly all of which are protected by the City of Arcadia, as is described in further detail
in Section IV, Biological Resources, of this Initial Study. As stated in the Project Description of this
Initial Study, these protected trees provide a visual barrier between the Proposed Project and
6 City of Arcadia, Arcadia General Plan Land Use and Community Design Element, November 2010, page 2-21.
Artis Senior Housing Project
Draft Initial Study Page 24 April 2020
surrounding uses and maintaining the existing visual character of the Project area.7 Therefore, because
of the Project Site’s distance from the nearest officially designated scenic highway and the lack of
impacts to scenic resources on the Project Site, the Proposed Project would have a less-than-
significant impact on scenic resources, such as trees, rock outcroppings, or historic buildings within a
State scenic highway.
c) Would the project, in non-urbanized areas, substantially degrade the existing visual
character or quality of public views of the site and its surroundings? (Public views are
those that are experienced from publicly accessible vantage point.) If the project is in an
urbanized area, would the project conflict with applicable zoning and other regulations
governing scenic quality?
Less Than Significant Impact. The Proposed Project would be located in a fully urbanized area,
where there is a variety of nonresidential and residential land uses and extensive urban infrastructure
improvements (see Figure A-14, Aerial View of Project Site and Surroundings). For purposes of
determining impact significance for projects within urbanized areas, a project is evaluated for whether
it would conflict with applicable zoning or other regulations governing “scenic quality.” The term
“scenic quality” is not specifically defined in the threshold language of Appendix G of the CEQA
Guidelines. No applicable federal or State regulations pertain to aesthetic impact; however, the
Proposed Project would need to comply with Arcadia Municipal Code regulations governing scenic
quality for areas zoned General Commercial.
The Project is consistent with the underlying General Commercial (C-G) zone because the
development of a residential care facility is allowed with an approved Conditional Use Permit (CUP)
from the City.8 However, the Project would require a zone change to remove an existing Architectural
Design (D) Overlay Zone and an Automobile Parking (P) Overlay Zone from the Project Site.
While the Proposed Project would conflict with the existing overlay zones covering the Project Site,
the Proposed Project would be consistent with underlying City zoning upon approval of a CUP.
Further, the Arcadia Development Code does not contain any specific zoning regulations that govern
scenic quality other than the protected tree ordinances described in Section IV, Biological Resources,
of this Initial Study. As stated above, all protected trees on the Project Site would be preserved in
place, providing visual barriers between the Proposed Project and surrounding uses and maintaining
the existing visual character of the Project vicinity, as presented in Figure A-13, Proposed
Landscape Plan. Per the Protected Tree Report, available as Appendix A and further discussed in
Section IV, Biological Resources, of this Initial Study, no mitigation measures to offset tree removals
would be required as part of the Proposed Project.9 Therefore, the Proposed Project would be
consistent with applicable zoning and other regulations governing scenic quality, and impacts would
be less than significant.

d) Would the project create a new source of substantial light or glare which would adversely
affect day or nighttime views in the area?
Less Than Significant Impact. The Project Site is currently developed with an existing Coco’s
building, which is surrounded by a surface parking lot and scattered landscaped areas. Existing sources
of light on the Project Site include building security lights on the restaurant building and pole-mounted
parking lot lights. The area surrounding the Project Site is highly urbanized and, therefore, is already
impacted by nighttime lighting from streetlights along Colorado Boulevard and Michillinda Avenue,
as well as traffic signals at the intersection of Colorado Boulevard and Michillinda Avenue, vehicle
headlights, and existing parking lot and building security lights at the commercial and gasoline station
uses across Michillinda Avenue from the Project Site. The residential neighborhoods south and east
of the Project Site do not contribute substantial nighttime lighting to the Project vicinity, apart from
residential security and landscape lighting, and overhead streetlights located along North Altura Road
and Altura Terrace.
The Proposed Project would contain multiple new sources of nighttime lighting, such as security
lighting on internal walkways, overhead LED lights in the parking areas, and lights at building
entrances, as well as accent lights along walking paths adjacent to landscaped areas and vehicle
headlights from those entering and exiting the Project Site. The Proposed Project would be required
to demonstrate compliance with Section 9103.01.120(D) of the Arcadia Development Code as part of
the City’s design review process, which limits potential light and glare impacts by requiring that lights
be directed downward and shielded/recessed to avoid spillage to adjacent properties and prohibits
flashing or roof-mounted lights that are directed outward. This Arcadia Development Code section
also prohibits light fixtures that are inappropriate for the scale, intensity, and height of the use they
are serving. Further, the Project would be allowed one sign, the lighting of which would have to
comply with City of Arcadia sign regulations.10 Additionally, the Project would not utilize glossy or
reflective construction materials that would generate significant amounts of glare off-site. Therefore,
the Project would not generate excessive light or glare, and by complying with lighting regulations in
the Arcadia Development Code, would result in a less-than-significant impact on day or nighttime
views in the Project area.

a) Would the project convert Prime Farmland, Unique Farmland, or Farmland of Statewide
Importance (Farmland), as shown on the maps prepared pursuant to the Farmland
Mapping and Monitoring Program of the California Resources Agency, to non-agricultural
use?
No Impact. As stated in the Project Description of this Initial Study, the Project Site is located in a
fully urbanized part of the City of Arcadia, where the built environment consists of a mixture of single-
family residences, commercial buildings, and major highway infrastructure. The Project Site is
currently developed with a Coco’s restaurant, which is surrounded by a surface parking lot and
ornamental landscaping. No agricultural uses or operations occur on-site or in the vicinity of the
Project Site. Additionally, neither the Project Site nor the area surrounding it are mapped as Prime
Farmland, Unique Farmland, or Farmland of Statewide or Local Importance pursuant to the Farmland
Mapping and Monitoring Program of the California Department of Conservation.11 Therefore, the
Project would not convert farmland to a non-agricultural use, and no impact would occur.
b) Would the project conflict with existing zoning for agricultural use, or a Williamson Act
contract?
No Impact. The Project Site is zoned as C-G (General Commercial) by the City and designated for
Commercial in the City’s General Plan. Agricultural uses are not permitted on properties zoned C-G.

Further, neither the Project Site nor the surrounding area is subject to a Williamson Act contract.12
Therefore, the Project would not conflict with existing zoning for agricultural uses or a Williamson
Act contract, and no impact would occur.
c) Would the project conflict with existing zoning for, or cause rezoning of, forest land (as
defined in Public Resources Code section 12220(g)), timberland (as defined by Public
Resources Code section 4526), or timberland zoned Timberland Production (as defined by
Government Code section 51104(g))?
No Impact. The Project Site is zoned as C-G (General Commercial) by the City and designated for
Commercial in the City’s General Plan. Accordingly, the Project Site does not include any forestland
or timberland and is almost entirely covered by man-made, impervious surfaces (i.e., building and
surface parking lot). Therefore, the Project would not conflict with existing zoning for, or cause
rezoning of, forestland, timberland, or timberland zoned Timberland Production, and no impact
would occur.
d) Would the project result in the loss of forest land or conversion of forest land to non-forest
use?
No Impact. The Project Site is located in a fully urbanized area and does not include any forestland
or timberland. Therefore, the Project would not result in the loss or conversion of forestland to non-
forest use, and no impact would occur.
e) Would the project involve other changes in the existing environment which, due to their
location or nature, could result in conversion of Farmland, to non-agricultural use or
conversion of forest land to non-forest use?
No Impact. As stated in the response to Checklist Question II.c, above, the Project Site is fully
urbanized and almost entirely covered by impervious surfaces. While the Proposed Project would alter
the Project Site, resulting in a greater amount of pervious areas due to the increase in landscaped areas,
the Project would not result in conversion of farmland to non-agricultural use or forestland to non-
forest use, and no impact would occur.

AIR QUALITY:
Where available, the significance criteria established by the applicable air quality management district or air pollution

܆ ܆ ܈ ܆
Discussion
a) Would the project conflict with or obstruct implementation of the applicable air quality
plan?
Less Than Significant Impact. The City of Arcadia is located within the South Coast Air Basin
(Basin), which is bounded by the San Gabriel, San Bernardino, and San Jacinto Mountains to the north
and east and by the Pacific Ocean to the south and west. The South Coast Air Quality Management
District (SCAQMD) has jurisdiction in the Basin, which has a history of recorded air quality violations
and is an area where both State and federal ambient air quality standards are exceeded.13 Areas that
meet ambient air quality standards are classified as attainment areas, while areas that do not meet these
standards are classified as nonattainment areas. The air quality in the Los Angeles County portion of
the Basin does not meet the ambient air quality standards for ozone (O 3), coarse particulate matter
(PM10), fine particulate matter (PM2.5), and lead and is therefore classified as a nonattainment area for
these pollutants.14 The SCAQMD is required to reduce emissions of air pollutants for which the Basin
is in federal nonattainment (i.e., O3 and PM2.5).
In order to reduce emissions, the SCAQMD adopted the 2016 Air Quality Management Plan (AQMP),
which establishes a program of rules and regulations directed at reducing air pollutant emissions and
achieving State and federal air quality standards.15 The 2016 AQMP is a regional and multiagency
effort including the SCAQMD, the California Air Resources Board (CARB), the Southern California
Association of Governments (SCAG), and the U.S. Environmental Protection Agency (USEPA). In
addition to the AQMP, the SCAQMD regulates construction activities through Rule 403, which
requires that excessive fugitive dust emissions be controlled by regular watering or other dust
prevention measures, thus greatly reducing PM10 and PM2.5 concentrations.

15 South Coast Air Quality Management District, Final 2016 Air Quality Management Plan, March 2017.
Artis Senior Housing Project
Draft Initial Study Page 29 April 2020
The 2016 AQMP pollutant control strategies are based on the latest scientific and technical
information and planning assumptions, including the 2016-2040 Regional Transportation
Plan/Sustainable Communities Strategy (RTP/SCS), updated emission inventory methodologies for
various source categories, and SCAG’s latest growth forecasts.16 SCAG’s latest growth forecasts were
defined in consultation with local governments and with reference to local general plans. Therefore,
the SCAQMD considers projects that are consistent with the 2016 AQMP to also have less-than-
significant cumulative impacts.17
Criteria for determining consistency with the 2016 AQMP are defined by the following indicators:
Criterion 1:
x The Proposed Project will not result in an increase in the frequency or severity of existing air quality violations,
or cause or contribute to new violations, or delay the attainment of air quality standards or the interim emissions
reductions specified in the AQMP.
Since this criterion pertains to pollutant concentrations, rather than to total regional emissions, an analysis
of the Project’s pollutant emissions relative to localized pollutant concentrations is used as the basis for
evaluating project consistency. As discussed in the response to Checklist Question III.c, below, localized
emissions of CO, NOX, PM10, and PM2.5 generated by the Project would be less than significant. Therefore,
the Proposed Project would not result in an increase in the frequency or severity of existing air quality
violations. Because reactive organic gases (ROGs) are not a criteria pollutant, there is no ambient standard
or localized threshold for ROGs. Due to the role ROGs play in O3 formation, it is classified as a precursor
pollutant and only a regional emissions threshold has been established. Further, as discussed in the
response to Checklist Question III.b, below, the Proposed Project would result in emissions below the
SCAQMD thresholds. Therefore, the Proposed Project would not have the potential to cause or affect a
violation of the ambient air quality standards. Finally, the Proposed Project would result in less-than-
significant impacts with regard to localized emissions during Project construction and operation. As such,
the Proposed Project would not delay the timely attainment of air quality standards or 2016 AQMP
emissions reductions and, therefore, meets the first criterion for consistency with the 2016 AQMP.
Criterion 2:
x The Proposed Project will be consistent with the population, housing, and employment growth projections utilized
in the preparation of the AQMP and will implement all feasible air quality mitigation measures.
A project is consistent with the 2016 AQMP in part if it is consistent with the population, housing, and
employment assumptions that were used in the development of the 2016 AQMP. In the case of the 2016
AQMP, the basis for the projections of air pollutant emissions include the Arcadia General Plan and
SCAG’s RTP/SCS. The RTP/SCS also provides socioeconomic forecast projections of regional
population growth.
The Project proposes to construct a senior living facility and associated surface parking lot. The existing
General Plan land use designation for the Project Site is Commercial, with a corresponding zoning of C-
G, General Commercial. Further, the Project Site is within two municipal overlay zones, the Architectural

Design overlay zone and the Automobile Parking overlay zone. While the Proposed Project would conflict
with the existing overlay zones covering the Project Site, the Proposed Project would be consistent with
the underlying City zoning upon approval of a CUP, as further discussed in response to Checklist Question
XI.b, below. Therefore, the Proposed Project is consistent with the General Plan. The population, housing,
and employment forecasts, which are adopted by SCAG’s Regional Council, are based on the local plans
and policies applicable to the City. As the SCAQMD has incorporated these same projections into the
2016 AQMP, it can be concluded that the Proposed Project would be consistent with the projections.
The Proposed Project would not require mitigation and would result in less-than-significant air quality
impacts, as described in responses to Checklist Questions III.b through III.d, below. Further, compliance
with all emissions reduction regulations established by the SCAQMD, such as Rule 403 controlling fugitive
dust, would be required. As such, the Proposed Project meets the second AQMP consistency criterion.
In conclusion, the Proposed Project would not result in a long-term impact on the region’s ability to meet
State and federal air quality standards. As discussed above, the Proposed Project’s long-term influence
would also be consistent with the SCAQMD’s and SCAG’s goals and policies and is, therefore, considered
consistent with the 2016 AQMP. As such, impacts would be less than significant.
b) Would the project result in a cumulatively considerable net increase of any criteria
pollutant for which the project region is non-attainment under an applicable federal or
state ambient air quality standard?
Less Than Significant Impact. The Project Site is located in the Basin, which is considered a
nonattainment area for certain criteria pollutants. The Project would involve demolition, grading, and other
construction activities, and would result in long-term operations at the Project Site; therefore, it would
contribute to regional and localized pollutant emissions during construction (short-term) and Project
occupancy (long-term). Further discussion of construction-related and operation-related emissions are
provided below.
Construction
The Project involves construction activities associated with demolition, grading, paving, building
construction, and architectural coating phases. It is anticipated that the Project would be constructed over
approximately 19 months. Variables factored into estimating the total construction emissions include the
level of activity, length of construction period, number of pieces and types of equipment in use, site
characteristics, weather conditions, number of construction personnel, and the amount of materials to be
transported on- or offsite. The analysis of daily construction emissions has been prepared utilizing the
California Emissions Estimator Model (CalEEMod) version 2016.3.2.18 Refer to Appendix B, Air
Quality/Greenhouse Gas/Energy worksheets, for the CalEEMod outputs and results. Table III-1
presents the anticipated daily short-term construction emissions associated with the Project.

maintaining mobile and other construction equipment; replacing ground cover in disturbed areas
quickly; watering exposed surfaces three times daily; covering stockpiles with tarps; watering all haul
roads twice daily; and limiting speeds on unpaved roads to 15 miles per hour.
Source: Refer to Appendix B for detailed model input/output data.
Construction activities, such as land clearing and ground disturbance, are a source of fugitive dust
emissions that may have a substantial, temporary impact on local air quality. Fugitive dust emissions vary
substantially from day to day, depending on the level of activity, specific operations, and weather
conditions, and would be short term, ceasing upon Project completion. As stated above, SCAQMD Rule
403 requires that excessive fugitive dust emissions be controlled by regular watering or other dust
prevention measures. Adherence to SCAQMD Rule 403 would greatly reduce PM10 and PM2.5
concentrations. As shown in Table III-1, total PM10 and PM2.5 emissions would not exceed the SCAQMD
thresholds during construction. Other construction-related exhaust emissions would result from the
transport of machinery and supplies to and from the Project Site and emissions produced by equipment
used on-site. As presented in Table III-1, construction equipment and worker vehicle exhaust emissions
(SO2, CO, and NOx) would be below the established SCAQMD significance thresholds.19
In addition to gaseous and particulate emissions, the application of asphalt and surface coatings creates
ROG emissions, which are O3 precursors. As required, all architectural coatings for the proposed
structure would comply with SCAQMD Rule 1113, Architectural Coating, which provides
specifications on painting practices and regulates the ROG content of paint.
As shown in Table III-1, Project-related total daily construction emissions of particulate matter,
equipment and vehicle exhaust, and ROG emissions would not exceed the SCAQMD significance
thresholds. As such, air quality impacts would be less than significant.
Operation
Emissions during Project operation would be predominantly associated with motor vehicle use
(mobile source emissions). To a lesser extent, area sources, such as the use of landscape maintenance
equipment, and architectural coatings, as well as energy sources, such as non-hearth natural gas and
19 South Coast Air Quality Management District, SCAQMD Air Quality Significance Thresholds, March 2015.

As shown in Table III-2, the Project would generate a substantial reduction in mobile source
emissions. This is because the Project would result in a net reduction of approximately 374 daily
vehicle trips as compared with existing conditions (Coco’s Restaurant).20 This net reduction in vehicle
trips is discussed further in Section XVII, Transportation/Traffic, of this Initial Study. Additionally,
area source emissions, such as emissions generated from consumer products, architectural coatings,
and internal combustion landscaping equipment, would result in a modest increase over existing
conditions. As shown in Table III-2, the total daily emissions from mobile, area source, and energy
emissions would not exceed SCAQMD thresholds for ROG, NO X, CO, SOX, PM10, or PM2.5. Thus,
operational air quality impacts would be less than significant.
c) Would the project expose sensitive receptors to substantial pollutant concentrations?
Less Than Significant Impact. Sensitive receptors are defined as facilities or land uses that include
members of the population that are particularly sensitive to the effects of air pollutants. Examples of
these sensitive receptors are residences, schools, hospitals, and daycare centers. CARB has identified
the following groups of individuals as the most likely to be affected by air pollution: the elderly over
65, children under 14, athletes, and persons with cardiovascular and chronic respiratory diseases, such
as asthma, emphysema, and bronchitis.21 In order to identify impacts to sensitive receptors, the
SCAQMD recommends addressing localized significance thresholds (LSTs) for construction and

operations impacts (area sources only).22 The closest sensitive receptors are residences adjoining the
Project Site to the east and south. These sensitive receptors may be potentially affected by air pollutant
emissions generated during on-site construction activities
Table III-3 presents the localized construction-related emissions for NOX, CO, PM10, and PM2.5 in
comparison to the appropriate LST designated by SCAQMD. The localized emissions presented in
Table III-3 are less than the emissions displayed in Table III-2 because localized emissions include
only on-site emissions (i.e., from construction equipment and fugitive dust) and do not include off-
site emissions (i.e., from hauling activities). As shown in Table III-3, the Project’s localized
construction emissions would not exceed the LST with adherence to SCAQMD rules and
requirements. Therefore, localized significance impacts from construction would be less than
significant.

a Modeling assumptions include compliance with SCAQMD Rule 403 which requires properly
maintaining mobile and other construction equipment; replacing ground cover in disturbed areas quickly;
watering exposed surfaces three times daily; covering stockpiles with tarps; watering all haul roads twice
daily; and limiting speeds on unpaved roads to 15 miles per hour.

e The LST was determined using Appendix C of the SCAQMD Final Localized Significant Threshold
Methodology guidance document for pollutants NOX, CO, PM10, and PM2.5. The LST was based on the
anticipated daily acreage disturbance for construction (the thresholds for 2 acres were used), the distance
to sensitive receptors (25 meters), and the source receptor area (SRA 9).
Source: Refer to Appendix B for detailed model input/output data.
Regarding operational emissions, SCAQMD states that LSTs would apply to the operational phase of
a Proposed Project if the Project includes stationary sources or attracts mobile sources that may spend
extended periods queuing and idling at the site (e.g., warehouse or transfer facilities).23 Because the
Proposed Project does not include such uses, no long-term LST analysis is needed and operational
LST impacts would be less than significant.

Therefore, because the Project would not exceed short-term or long-term LSTs, the Project would
not expose sensitive receptors to substantial pollutant concentrations, and air quality impacts would
be less than significant.
d) Would the project result in other emissions (such as those leading to odors) adversely
affecting a substantial number of people?
Less Than Significant Impact. According to the SCAQMD CEQA Air Quality Handbook, land uses
associated with odor complaints typically include agricultural uses, wastewater treatment plants, food
processing plants, chemical plants, composting, refineries, landfills, dairies, and fiberglass molding.24
The Proposed Project does not include any uses identified by the SCAQMD as being associated with
odors.
Construction activities associated with the Project may generate other emissions and detectable odors
from heavy-duty equipment exhaust and architectural coatings. However, construction-related
emissions and odors would be short term in nature and cease upon Project completion. In addition,
the Project would be required to comply with the California Code of Regulations, Title 13,
Sections 2449(d)(3) and 2485, which minimizes the idling time of construction equipment either by
shutting it off when not in use or by reducing idling time to no more than five minutes. This would
further reduce the detectable odors from heavy-duty equipment exhaust. The Project would also be
required to comply with the SCAQMD Regulation XI, Rule 1113 – Architectural Coatings, which
would minimize odor impacts from ROG emissions during architectural coating. Any odor impacts
to existing adjacent land uses would be short term and minimal. As such, the Project would not result
in other emissions (such as those leading to odors) adversely affecting a substantial number of people,
and impacts would be less than significant.

a) Would the project have a substantial adverse effect, either directly or through habitat
modifications, on any species identified as a candidate, sensitive, or special status species
in local or regional plans, policies, or regulations, or by the California Department of Fish
and Game or U.S. Fish and Wildlife Service?
Less than Significant Impact. The Project Site is located in a fully urbanized area where the built
environment consists of a mixture of single-family residential and commercial buildings and major
highway infrastructure. The Project Site is currently developed with a restaurant building, which is
surrounded by surface parking and landscaping. As stated in the Project Description of this Initial
Study, mature eucalyptus trees flank the western and eastern sides of the restaurant building.
Additionally, there are decorative shrubs and turf along the northern, eastern, and western façades of
the building, with one mature fern pine near the northeastern corner of the building. There is a mix
of existing trees along the perimeter of the Project Site, serving as landscape buffers between the
Project Site and neighboring streets to the north and west and the residential neighborhoods to the
east and south. In total, there are 72 trees located on the Project Site. According to the U.S. Fish and
Wildlife Service (USFWS), the only threatened or endangered species that have potential of occurring
in this part of Arcadia are the California condor, the coastal California gnatcatcher, and the Braunton’s
milk-vetch flowering plant.25 While there are 72 trees on the Project Site, the Site does not contain any
native habitat that would support the California condor or the coastal California gnatcatcher. The
Project Site’s manicured landscaping does not support native plant species, such as the Braunton’s
milk-vetch. Due to the disturbed nature of the Project Site, the Project Site would not support special-
status species listed by the USFWS, or species listed on the California Department of Fish and

Wildlife’s (CDFW) Special Plant and Animal Lists.26 Further, the Arcadia General Plan does not
identify any sensitive or special-status species, apart from protected trees, which are discussed in the
response to Checklist Question IV.e of this Initial Study. Therefore, the Project would not have a
substantial adverse effect, either directly or through habitat modification, on any species identified as
a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by
the CDFW or USFWS. As such, impacts would be less than significant.
b) Would the project have a substantial adverse effect on any riparian habitat or other
sensitive natural community identified in local or regional plans, policies, regulations or
by the California Department of Fish and Game or US Fish and Wildlife Service?
No Impact. As previously stated, the Project Site is located in an urbanized area and is currently
developed as a restaurant with associated parking and landscaping. No riparian or other sensitive
natural community exists on the Project Site or in the immediate surrounding area.27,28 Further, the
Project Site is not located in or adjacent to a Biological Resource Area or Significant Ecological Area
as defined by the County of Los Angeles.29 Additionally, there are no other sensitive natural
communities or critical habitat identified by the CDFW or USFWS located on or adjacent to the
Project Site.30,31,32 Therefore, the Proposed Project would not have a substantial adverse effect on any
riparian habitat or other sensitive natural community, and no impact would occur.
c) Would the project have a substantial adverse effect on state or federally protected
wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct
removal, filling, hydrological interruption, or other means?
No Impact. Section 404 of the Clean Water Act defines wetlands as “those areas that are inundated
or saturated by surface or groundwater at a frequency and duration sufficient to support, and that
under normal circumstances do support, a prevalence of vegetation typically adapted for life in
saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.”
The Project Site is located in an urbanized area and is mostly covered by impervious surfaces except
for some ornamental landscaping in front of the existing restaurant building and along the site
frontages. There are no water bodies or federally protected wetlands on the Project Site or in the
immediate vicinity.33,34 Therefore, the Project would not have an adverse effect on State or federally
protected wetlands, and no impact would occur.

d) Would the project interfere substantially with the movement of any native resident or
migratory fish or wildlife species or with established native resident or migratory wildlife
corridors, or impede the use of native wildlife nursery sites?
Less Than Significant with Mitigation Incorporated . There are no waters or streams present on
the Project Site. Therefore, the Proposed Project would not impact or interfere with the movement
of any native resident or migratory fish. Wildlife corridors are typically made up of undeveloped
wildlife habitat and open space linkages between larger patches of wildlife habitat. Habitat linkages
may also include more tenuous linkages like narrow vegetated pathways or islands of habitat that act
as stepping stones between larger habitat areas for some species. The Project Site has been highly
disturbed and is surrounded by developed, urban land uses; however, there are 72 existing trees on
the Project Site, which could provide habitat to animals capable of flight (i.e., birds).35
The Coco’s building, trees, and ornamental landscaping may provide suitable roosting and nesting
habitat for bird species. Migratory nongame native bird species are protected under the federal
Migratory Bird Treaty Act (MBTA) of 1918 (50 CFR Section 10.13). Sections 3503, 3503.5, and 3513
of the California Fish and Game Code prohibit take of all birds and their active nests including raptors
and other migratory nongame birds (as listed under the federal MBTA). The Proposed Project would
result in the removal of unprotected trees, the existing Coco’s building, and other landscaping, which
could be used as habitat for nesting birds. While migratory bird species are considered highly mobile
and would naturally avoid areas with loud construction noise, removal of potential nesting habitat
would result in the potential for minor impacts. As such, Mitigation Measure BIO-1 would be
implemented, which would reduce impacts on migratory wildlife species to a less-than-significant level
with mitigation incorporated.
BIO-1 Tree removal shall not occur during the local nesting season (February 1 to September
15 for nesting birds and February 1 to June 30 for nesting raptors), to the extent
practicable. If any construction or tree removal occurs during the nesting season, a
nesting bird survey shall be conducted by a qualified biologist prior to commencement
of grading or removal of any trees on the property. If the biologist determines that
nesting birds are present, restrictions may be placed on construction activities in the
vicinity of the nest observed until the nest is no longer active, as determined by the
biologist based on the location of the nest, type of the construction activities, the
existing human activity in the vicinity of the nest, and the sensitivity of the nesting
species. Grading and/or construction may resume in this area when a qualified
biologist has determined that the nest is no longer occupied, and all juveniles have
fledged. This measure shall be implemented to the satisfaction of the City of the
Planning & Community Development Administrator or Designee.
e) Would the project conflict with any local policies or ordinances protecting biological
resources, such as a tree preservation policy or ordinance?
Less Than Significant with Mitigation Incorporated. The City of Arcadia has a Tree Preservation
Ordinance (TPO) that protects trees with a diameter of 12 inches or greater (or greater than 10 inches
in diameter if there are multiple trunks), as well as street trees.36 Several trees are considered

“unprotected” regardless of their size, including fruit trees, Brazilian pepper trees, palm trees,
eucalyptus trees, and Italian cypress trees. Of the 72 trees located on the Project Site, 12 are considered
protected under the TPO with all but two of these protected trees considered to be in good health.
There are four additional protected trees that are off-site but have canopies that encroach onto the
Project Site. In total, there are 16 protected trees located on the Project Site or that have canopies that
extend onto the Project Site. As discussed in the Protected Tree Report, included as Appendix A of
this Initial Study, these protected trees include species, such as fern pines, carrotwoods, Japanese pear,
southern magnolias, deodar cedar, coast redwood, and Canary Island pines, and are primarily located
along the perimeter of the Project Site. In particular, Tree No. 49 (see Appendix A), a protected deodar
cedar located on the Project Site’s Colorado Boulevard frontage, is in fair condition but is showing
branch die-back.
The Proposed Project would remove a total of 18 unprotected trees, which include a mix of Victorian
box trees, lemon-scented gum trees, a fern pine, and an evergreen pear tree. Of the 18 unprotected
trees to be removed, 13 trees are located in the center of the Project Site, around the existing restaurant
building; two trees are flanking the existing driveway onto Colorado Boulevard; two trees are located
in a planter in the southeastern corner of the parking lot; and one dead tree stump is located on the
Project Site’s Colorado Boulevard frontage. No healthy, protected trees would be removed as part of
Project Site modifications. Of the 16 protected trees that are on or adjacent to the Project Site, all 12
of the on-site protected trees would experience some light grading within their immediate area, less
than 6 inches deep within the dripline of the tree. The Protected Tree Report estimates that the
Proposed Project would remove or sever less than 20 percent of the total root mass of each of these
protected trees. Project-related construction activities would not encroach upon the four off-site
protected trees. Accordingly, the Protected Tree Report determined that the Project would not
adversely affect the long-term viability of the protected trees on or adjacent to the Project Site. As
such, no protected trees would be removed or irrevocably damaged as part of Project-related grading
and construction.
While some minor damage to the protected tree root systems are anticipated as part of the Proposed
Project, implementation of Mitigation Measure BIO-2 is required to prevent substantial damage to
on- and off-site protected trees, via soil compaction or grading encroachment into protected tree root
systems. The goal of Mitigation Measure BIO-2 would be to enclose the largest possible amount of
space underneath the tree so that the heavy equipment required for demolition and construction can
be routed away from root zones. Further, the TPO requires an applicant to demonstrate that a
proposed project’s landscape plan is consistent with the TPO. Therefore, with implementation of
Mitigation Measure BIO-2 to meet the requirements of the TPO, the Proposed Project would not
conflict with the City’s TPO, and impacts would be less than significant with mitigation incorporated.
BIO-2 Prior to issuance of a building permit, the applicant shall demonstrate that the Project
landscaping plan and planned construction are consistent with the City’s Tree
Protection Ordinance and the Protected Tree Study. The tree protection activities shall
include the following:
1. Prior to demolition, the contractor and consulting arborist shall meet on-site to
make sure tree protection zones are established around all protected trees to be
preserved and to review the goals for the tree protection plan.
2. Tree protection zone fences shall be placed around each protected tree. Fences
shall be at least 4 feet tall and constructed of chain-link fencing secured on metal
Artis Senior Housing Project
Draft Initial Study Page 39 April 2020
posts. Where fences are not feasible (e.g., in haul routes or areas where workers
will need frequent access), soil and root protection material can be installed.
3. The contractor shall maintain the fences and/or soil protection material
throughout the completion of the Project. No staging of materials or equipment
or washing out shall occur within the fenced protected zones.
4. Trees should be irrigated throughout the year. A deep watering that provides
good soil moisture to a depth of 16 inches is optimal. The trees shall be deeply
water once every 21 to 28 days during the summer and fall seasons when rain is
unlikely.
5. For Tree No. 49, a protected deodar cedar located on the Project Site’s Colorado
Boulevard frontage, the deadwood shall be removed to prevent the dead
branches from falling. However, no reduction pruning in the live crown of the
tree is required. The tree shall be monitored for its health during the life of the
Project, and irrigation shall occur at the same frequency of the other trees.
6. The arborist shall monitor a few critical phases of the Project, including pre-
demolition, to direct the installation of protective fences and soil protection
measures; grading and excavation; any utility or drainage trenching that is
required within a tree protection zone; and a final evaluation during the landscape
installation phase.
7. Additional construction best practices described in the Protected Tree Report
shall be implemented.
f) Would the project conflict with the provisions of an adopted Habitat Conservation Plan,
Natural Community Conservation Plan, or other approved local, regional, or state habitat
conservation plan?
No Impact. There are no adopted, approved, or proposed habitat conservation plans, natural
community conservation plans, or other approved local, regional, or State conservation plans that
cover habitats located in the City of Arcadia.37 Therefore, the Proposed Project would not conflict
with such plans, and no impact would occur.

Discussion
The analysis in this section is based on the “Cultural Resources Identification Memorandum for the
Artis Senior Living Project” prepared by Michael Baker International in January 2020, included as
Appendix C of this Initial Study. The memo report summarized the methods and results of a South
Central Coastal Information Center (SCCIC) records search, literature review, and historical map
review to determine whether the Project would result in significant impacts to cultural resources,
including historical and archaeological resources.
a) Would the project cause a substantial adverse change in the significance of a historical
resource pursuant to § 15064.5?
No Impact. No historical resources (built environment) were identified on the Project Site. The
current restaurant building, built in 1976, does not meet the age requirement for evaluation for
eligibility for listing in the California Register of Historical Resources (California Register) and,
therefore, is not a historical resource as defined by CEQA Guidelines Section 15064.5(a). Further,
there are no cultural resources listed or eligible for listing in the California Register within the
immediate vicinity of the Project Site (i.e., within 1.5 blocks of the Project Site). Because physical
alterations associated with the Proposed Project would not extend beyond the Project Site, there
would be no impact to on-site or off-site historical resources as a result of the Project’s
implementation. Therefore, the Project would not cause a substantial adverse change in the
significance of a historical resource pursuant to CEQA Guidelines Section 15064.5, and no impact to
historical resources would occur.
b) Would the project cause a substantial adverse change in the significance of an
archaeological resource pursuant to § 15064.5?
Less than Significant Impact with Mitigation Incorporated . The Project Site is fully paved and
landscaped with no exposed soils. No archaeological resources were identified on the Project Site or
within a quarter-mile of the Project Site. The Project Site was first developed with a hotel and
restaurant known as Eaton’s Santa Anita Hotel and Restaurant between 1940 and 1975 when it was
demolished for the current 1976-built restaurant. No other historic literature or maps indicate
occupation or development of the Project Site prior to circa 1940. Furthermore, neither the current
building nor the previous Eaton’s restaurant building was identified as significant in the records search
Artis Senior Housing Project
Draft Initial Study Page 41 April 2020
or literature review (see Appendix C of this Initial Study). Accordingly, the site sensitivity for
subsurface archaeological resource is considered low because the Project Site has been developed and
redeveloped. However, the potential exists for unanticipated discovery of archaeological resources
during Project-related ground disturbance activities. Therefore, Mitigation Measure CUL-1 is
required to ensure that impacts to archaeological resources pursuant to CEQA Guidelines Section
15064.5 would be less than significant with mitigation incorporated.
Mitigation Measure
CUL‐1 Treatment of previously unidentified archaeological deposits. If suspected
prehistoric or historical archaeological deposits are discovered during construction, all
work within 25 feet of the discovery shall be redirected and a Secretary of the Interior
Professional Qualified archaeologist and/or Registered Professional Archaeologist
shall assess the situation and make recommendations regarding the treatment of the
discovery. Impacts to significant archaeological deposits shall be avoided if feasible,
but if such impacts cannot be avoided, the deposits shall be evaluated for their
eligibility for the California Register of Historical Resources. If the deposits are not
eligible, no further protection of the find is necessary. If the deposits are eligible,
impacts shall be avoided or mitigated. Acceptable mitigation may consist of, but is not
necessarily limited to, systematic recovery and analysis of archaeological deposits,
recording the resource, preparation of a report of findings, and accessioning recovered
archaeological materials at an appropriate curation facility.
c) Would the project disturb any human remains, including those interred outside of
dedicated cemeteries?
Less Than Significant Impact. The Project would not likely disturb any human remains, including
those interred outside of dedicated cemeteries. Research conducted as part of the preparation of the
“Cultural Resources Identification Memo Report for the Artis Senior Living Project” found no
indications of any past human burial activities on or near the Project Site. However, there is the
potential to discover buried human remains during Project-related earth-moving activities. According
to the California Health and Safety Code Section 7050.5, there must be no further excavation or
disturbance of a site or any nearby area reasonably suspected to overlie adjacent remains until the Los
Angeles County coroner has determined the manner and cause of any death, and the
recommendations concerning the treatment and disposition of the human remains have been made
to the person responsible for the excavation or to his or her authorized representative. Project
personnel/construction workers are prohibited to collect or move any human remains and associated
materials. If the human remains are of Native American origin, the coroner must notify the Native
American Heritage Commission (NAHC) within 24 hours of this identification. The NAHC will
immediately identify a Native American most likely descendant to inspect the site and provide
recommendations within 48 hours for the proper treatment of the remains and associated grave goods.
Accordingly, impacts related to the disturbance of human remains, including those interred outside of
dedicated cemeteries, would be less than significant with the Project’s compliance with California
Health and Safety Code Section 7050.5.

Discussion
a) Would the project result in potentially significant environmental impact due to wasteful,
inefficient, or unnecessary consumption of energy resources, during project construction
or operation?
Less Than Significant Impact.
This analysis focuses on three sources of energy that are relevant to the Proposed Project: electricity,
natural gas, and transportation fuel for vehicle trips associated with Project construction and new
development. The estimated construction fuel consumption is based on the Project’s construction
equipment list, timing/phasing, and hours of duration for construction equipment, as well as vendor,
hauling, and construction worker trips. The analysis of operational electricity/natural gas usage is
based on the CalEEMod version 2016.3.2 modeling results for the Project, which quantifies energy
use for the proposed occupancy. The Project’s estimated electricity/natural gas consumption is based
primarily on CalEEMod’s default settings for Los Angeles County and consumption factors provided
by Southern California Edison (SCE) and the Southern California Gas Company (SoCalGas) (the
electricity and natural gas providers, respectively, for the City of Arcadia and the Project Site). The
results of the CalEEMod modeling are included in Appendix B, Air Quality/Greenhouse
Gas/Energy Worksheets. The amount of operational fuel consumption was estimated using the
CARB Emissions Factor 2017 (EMFAC2017) computer program, which provides projections for
typical daily fuel (i.e., diesel and gasoline) usage in Los Angeles County, and the Project’s annual vehicle
miles traveled (VMT) outputs from CalEEMod.
Construction
Project construction would consume energy in two general forms: (1) the fuel energy consumed by
construction vehicles and equipment; and (2) bound energy in construction materials, such as asphalt,
steel, concrete, pipes, and manufactured or processed materials, such as lumber and glass.
Fossil fuels for construction vehicles and other energy-consuming equipment would be used during
site clearing, grading, and construction. Fuel energy consumed during construction would be
temporary and would not represent a significant demand on energy resources. In addition, some
incidental energy conservation would occur during construction through compliance with State
requirements that heavy-duty diesel equipment not in use for more than five minutes be turned off.
Project construction equipment would also be required to comply with the latest USEPA and CARB
Artis Senior Housing Project
Draft Initial Study Page 43 April 2020
engine emissions standards. These emissions standards require highly efficient combustion systems
that maximize fuel efficiency and reduce unnecessary fuel consumption. Due to increasing
transportation costs and fuel prices, contractors and owners have a strong financial incentive to avoid
wasteful, inefficient, and unnecessary consumption of energy during construction.
Substantial reductions in energy inputs for construction materials can be achieved by selecting building
materials composed of recycled materials that require substantially less energy to produce than non-
recycled materials. The Project-related incremental increase in the use of energy bound in construction
materials, such as asphalt, steel, concrete, pipes and manufactured or processed materials (e.g., lumber
and gas), would not substantially increase demand for energy compared to overall local and regional
demand for construction materials. It is reasonable to assume that production of building materials,
such as concrete, steel, etc., would employ all reasonable energy conservation practices in the interest
in minimizing the cost of doing business. As indicated in Table VI-1, the Project’s fuel consumption
from construction would be approximately 36,934 gallons, which would increase fuel use in the
County by 0.0069 percent. As such, construction would have a nominal effect on local and regional
energy supplies. It is noted that construction fuel use is temporary and would cease upon completion
of construction activities. There are no unusual Project characteristics that would necessitate the use
of construction equipment that would be less energy efficient than at comparable construction sites
in the region or State. Therefore, construction fuel consumption would not be any more inefficient,
wasteful, or unnecessary than other similar development projects of this nature. As such, impacts
related to energy conservation would be less than significant.

Operation
The Project’s estimated energy consumption is summarized in Table VI-1, which shows that the
Project’s electricity usage would constitute an approximate 0.0004-percent reduction from Los
Angeles County’s typical annual electricity consumption and an approximate 0.0007-percent reduction
from Los Angeles County’s typical annual natural gas consumption. The Project’s construction fuel
consumption would increase Los Angeles County’s consumption by 0.0069 percent. However, the
Project would generate a net decrease of approximately 374 daily trips when compared to the existing
use (i.e., Coco’s Restaurant). As a result, the Project’s operational vehicle consumption would decrease
Los Angeles County’s fuel consumption by 0.0002 percent.
Building Energy Demand
The Project would consume energy for interior and exterior lighting; heating, ventilation, and air
conditioning (HVAC) systems; refrigeration; electronics systems; appliances; and security systems. The
Project would be required to comply with Title 24 standards,38 which provide minimum efficiency
standards related to various building features, including appliances, water and space heating and
cooling equipment, building insulation and roofing, and lighting. Implementation of Title 24 standards
significantly reduces energy usage. Furthermore, the electricity provider, SCE, is subject to California’s
Renewables Portfolio Standard (RPS), which requires investor-owned utilities, electric service
providers, and community choice aggregators to increase procurement from eligible renewable energy
resources to 33 percent of total procurement by 2020 and to 50 percent of total procurement by 2030.
As indicated in Table VI-1, operational energy consumption would represent an approximate 0.0004-
percent reduction in electricity consumption and a 0.0007-percent reduction in natural gas
consumption from current countywide usage. Therefore, the Project would not result in the
inefficient, wasteful, or unnecessary consumption of building energy, and impacts related to energy
conservation would be less than significant.
Transportation Energy Demand
Pursuant to the Federal Energy Policy and Conservation Act of 1975, the National Highway Traffic
and Safety Administration (NTSA) is responsible for establishing additional vehicle standards and for
revising existing standards. Compliance with federal fuel economy standards is not determined for
each individual vehicle model. Rather, compliance is determined based on each manufacturer’s average
fuel economy for the portion of their vehicles produced for sale in the U.S. Table VI-1 provides an
estimate of the daily fuel consumed by vehicles traveling to and from the Project Site. As indicated in
Table VI-1, Project operations are estimated to reduce existing vehicle consumption by approximately
8,182 gallons of fuel per year, which would decrease the Los Angeles County’s automotive fuel
consumption by 0.0002 percent. The Project would not result in any unusual characteristics that would
result in excessive operational fuel consumption associated with vehicular travel. Fuel consumption
associated with Project-related vehicle trips would not be considered inefficient, wasteful, or
unnecessary in comparison to other similar developments in the region. As such, impacts related to
energy conservation would be less than significant.

b) Would the project conflict with or obstruct a state or local plan for renewable energy or
energy efficiency?
No Impact. The City adopted the 2019 Energy Action Plan Update (EAP), which updates the City’s
2012 Energy Action Plan. The City is part of the San Gabriel Valley Energy Wise Partnership
(SGVEWP), which is a collaboration between SCE, SoCalGas, the San Gabriel Valley Council of
Governments, and 29 cities in the San Gabriel Valley. Through the SGVEWP, member cities are able
to participate in the SCE Energy Leader Model, which recognizes cities for increasing their energy
efficiency in municipal facilities and communities, and participating in demand-response programs
and long-term strategic planning. Implementation of the EAP has allowed Arcadia to reach the second
highest level of energy efficiency, Gold, under the Energy Leader Model.
The 2019 EAP builds on the community goals and policies in the 2012 EAP and adds additional goals
and policies for City-owned properties. The 2019 EAP outlines three City energy conservation targets:
reduce municipal electricity usage by 780,662 kilowatt hours by 2023; achieve Platinum level status in
SCE’s Energy Leader Program; and complete three or more municipal energy-efficiency projects by
2023. As these goals are municipal targets, aimed at reducing electricity usage at City-owned and City-
controlled facilities, the Proposed Project’s energy reduction features would not contribute to or
obstruct the attainment of these goals. However, the Project’s overall energy-efficiency measures—
e.g., installing energy-efficient appliances, heaters, and HVAC systems; using water-efficient
landscaping (which would reduce the electricity used for water transport and treatment); and
incorporation of building code-mandated energy-efficient designs—would generally support the City’s
energy reduction goals. The Project’s energy consumption would be typical of senior living
development projects in Southern California and would not result in an increased energy demand
beyond the capacity of SCE or SoCalGas. As such, the Project would not conflict with or obstruct
any plans for renewable energy or energy efficiency, and, as such, no impact would occur.

Less Than Significant Impact. According to the City of Arcadia General Plan Safety Element, the
Raymond Hill Fault Zone and the Sierra Madre Fault Zone are the only active or potentially active
earthquake faults that pass through the City of Arcadia.39,40 In addition, two deep blind thrust faults
are located beneath Arcadia, i.e., the relatively shallow Elysian Park Fault and the relatively deep
Puente Hills Fault. These are considered blind thrust faults due to their depth and because the fault
movement consists of upward or thrusting action. The Safety Element states that there is also the
Eaton Wash groundwater barrier; however, this fault shows no surface geological evidence of
existence and the nature of this buried fault is unknown.41 The Raymond Fault traverses a large portion
of the City and has a potential to cause a 5-6-foot offset if severe ground shaking occurs. The Sierra
Madre Fault crosses the northern portion of the City and could result in large ground rupture
movements (possibly 10 feet or more in the event of a 7.2 magnitude earthquake).42

The Project Site is located north of the Raymond Fault and south of the Sierra Madre Fault. An
“inferred or possible groundwater barrier” fault runs directly west and south of the Project Site. As
displayed in Figure S-2 of the Safety Element, the Project Site is not located within the Alquist-Priolo
Earthquake Fault Zone for either the Sierra Madre Fault or the Raymond Fault; however, the Alquist-
Priolo Earthquake Fault Zone for the Raymond Fault is located just one-half mile southeast of the
Project Site.43 Further, the Project Site is not located within a Fault Hazard Management Zone, which
would require geologic investigations to be performed if conventional structures that are designed for
human occupancy are proposed within the zone.
While the Proposed Project is near these fault zones, the Proposed Project is subject to review by the
City of Arcadia Building Services Division to ensure compliance with aspects of the California
Building Standards Code pertaining to seismic safety (California Code of Regulations, Title 24), which
the City adopted into the City’s Code of Ordinances in 2010.44 Because the Project Site is located
outside of Alquist-Priolo Earthquake Fault and Hazard Management Zones identified above and
because the Project is required to adhere to building regulations dictating seismic safety, the Project
would not directly or indirectly cause potential adverse effects, including the risk of loss, injury, or
death involving rupture of a known earthquake fault. Therefore, potential impacts related to rupture
of a known earthquake fault would be less than significant.
a.ii) Would the project directly or indirectly cause potential substantial adverse effects,
including the risk of loss, injury, or death involving strong seismic ground shaking?
Less Than Significant Impact. As with most of Southern California, the Project Site is in an area
that is subject to strong ground shaking due to earthquakes on local and regional faults. As stated
above, the Raymond Fault and the Sierra Madre Fault are the only faults to traverse the City and are
located south and north of the Project Site, respectively. The 2019 California Building Code provides
procedures for earthquake-resistant structural design that include considerations for on-site soil
conditions, occupancy, and the configuration of the structure including the structural system and
height. With adherence to the seismic design parameters as outlined in the California Building Code,
the Project would not directly or indirectly cause potential substantial adverse effects, including the
risk of loss, injury, or death involving strong seismic ground shaking. Therefore, potential impacts
related to seismic ground shaking would be less than significant.
a.iii) Would the project directly or indirectly cause potential substantial adverse effects,
including the risk of loss, injury, or death involving seismic-related ground failure,
including liquefaction?
Less Than Significant Impact. Liquefaction is the loss of strength in generally cohesionless (granular),
saturated soils when the pressure of groundwater held within a soil or rock, in gaps between particles
(referred to as “pore-water pressure”) induced in the soil by a seismic event, becomes equal to or exceeds
the overburden pressure. Lateral spread or flow refers to landslides that commonly form on gentle slopes
and that have rapid fluid-like flow movement, like water. In general, lateral spreading is a result of
liquefaction.
The primary factors that influence the potential for liquefaction include groundwater table elevation; the
relative density of the soil; and the intensity and duration of ground shaking. The depth within which the

occurrence of liquefaction may impact surface improvements is generally identified as the upper 50 feet
below the existing ground surface.
According to the Safety Element, the Project Site is located within a liquefaction zone due to the relatively
shallow groundwater depth of approximately 40 feet.45 However, the 2019 California Building Code
provides requirements for earthquake-resistant structural design that include considerations for on-site soil
conditions, occupancy, and the configuration of the structure including the structural system and height.
Other mitigation guidance provided by the California Geological Survey (CGS) includes removal and/or
densification of liquefiable soils to eliminate liquefaction hazards.46 With adherence to the seismic design
parameters as outlined in the Cali fornia Building Code, incorporated into the Arcadia Municipal Code by
reference, and CGS guidance, the Project would not directly or indirectly cause potential substantial
adverse effects, including the risk of loss, injury, or death involving seismic-related ground failure, such as
liquefaction. Therefore, potential impacts related to seismic-related ground failure would be less than
significant.
a.iv) Would the project directly or indirectly cause potential substantial adverse effects,
including the risk of loss, injury, or death involving landslides?
No Impact. The Project Site is located in a fully urbanized area and is surrounded by single-family
residential buildings, a gas station, highway infrastructure (I-210), and a medium-rise commercial building.
The Project Site’s topography is relatively flat, with a slight slope to the southeast (a difference in elevation
of approximately 10 feet between the northwestern corner and the southeastern corner of the Project Site).
Further, the Project Site is not located within an earthquake-induced landslide hazard area, as identified by
the Safety Element. Accordingly, the Project would not directly or indirectly cause potential substantial
adverse effects, including the risk of loss, injury, or death involving landslides. Therefore, no impact related
to landslides would occur.
b) Would the project result in substantial soil erosion or the loss of topsoil?
Less Than Significant Impact. Because of the extensive ground alterations that have occurred on-site
since the Project Site was originally developed, it is unlikely that any native topsoil is remaining in the near
surface. There would, thus, be no impact involving loss of topsoil.
During construction of the Proposed Project, the uncovered soils on-site may become exposed to wind
or rainstorms and, thus, subject to erosion. The Proposed Project must comply with SCAQMD Rule 403,
Fugitive Dust, to reduce the amount of particulate matter in the ambient air due to man-made fugitive dust
sources by requiring actions to prevent, reduce, or mitigate fugitive dust emissions. This rule requires that
construction activities include a variety of best available control measures, including measures that would
prevent wind-induced erosion of uncovered soils, such as to apply chemical stabilizers to areas that would
remain inactive for 10 days or longer, replant disturbed areas as soon as practical, and suspend grading
when wind speeds exceed 25 miles per hour. Storm-related erosion of uncovered soils during construction
activities would be prevented by complying with the County of Los Angeles’ National Pollutant Discharge
Elimination System (NPDES) Construction General Permit requirements. These requirements are further
discussed in Section X.a, Hydrology and Water Quality, below. In general, the NPDES permit requires
construction activities to incorporate best management practices (BMPs) to prevent erosion and prevent
loose soils from washing off-site. In general, BMPs for the Proposed Project would include the use of

Draft Initial Study Page 49 April 2020
berms or drainage ditches to divert water around the site and preventing sediment from migrating off the
site by using temporary swales, silt fences, or gravel rolls. Additionally, because the Proposed Site is greater
than 1 acre, the City requires the preparation of a Stormwater Pollution Prevention Plan, which would
establish erosion and sedimentation controls, such as methods to minimize the footprint of the disturbed
area, controls to prevent tracking off-site, spill prevention, non-stormwater controls (i.e., vehicle washing),
and methods to protect native vegetation and trees. Therefore, the potential for soil erosion during any
construction activity would be reduced to less than significant through Project compliance with these
existing regulations.
Finally, the Proposed Project would result in almost the entire site covered in either impervious surfaces,
such as the building, surrounding parking areas, outdoor structures (i.e., outdoor gathering spaces, refuse
and generator enclosures, and storage shed), and concrete walkways, or managed landscaped areas.
Because almost the entire site would be covered by either impervious surfaces or managed gardens/turf
areas, there would be very little potential for wind- or storm-induced erosion during the long-term
operation of the Project. Accordingly, the Project would not result in soil erosion or the loss of topsoil.
Therefore, potential impacts related to soil erosion or the loss of topsoil would be less than significant.
c) Would the project be located on a geologic unit or soil that is unstable, or that would
become unstable as a result of the project, and potentially result in on- or off-site
landslide, lateral spreading, subsidence, liquefaction or collapse?
Less Than Significant Impact. As stated above, the Project Site’s topography is relatively flat, with
a slight slope to the southeast. Further, the Project Site is not located within an earthquake-induced
landslide hazard area, as identified by the Safety Element. Therefore, there would be no risk resulting
from on- or off-site landslide. Further, while the project is located in a liquefaction area, the Project
would be required to comply with seismic design parameters as outlined in the California Building
Code, incorporated into the Arcadia Municipal Code by reference. Further, compliance with CGS
guidance described above for addressing liquefaction hazards would reduce potential liquefaction
impacts to site improvements to a less-than-significant level.
Other hazards include subsidence, which is the compaction of the ground when large amounts of
groundwater or oil have been withdrawn from fine-grained sediments or when underlying limestone
deposits dissolve, as well as collapsible soils, which undergo a volume reduction when the pore spaces
become saturated with water, with the weight of overlying structures causing settlement. Both of these
hazards can result in building settlement and damage to foundations and walls. Subsidence may cause
differential settlement of the overlying structure and substantially more damage than if the structure
were to settle evenly throughout. Large-scale subsidence due to fluid withdrawal (water or oil) has not
been reported in or near the City.47 Therefore, it is unlikely that the Project Site is located on soils that
are vulnerable to subsidence or collapse. Nevertheless, the Project would be required to comply with
seismic safety design regulations required by the California Building Code or those described by the
CGS guidance, such as extending piles or caissons to non-collapsible soils, or utilizing various methods
of soil compaction prior to construction. These building regulations would provide appropriate
building design criteria needed to protect structural integrity of structures against such geologic
hazards. Accordingly, with compliance with required design criteria, the Project would not result in
on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse. Therefore, potential
impacts related to unstable soils would be less than significant.

d) Would the project be located on expansive soil, as defined in Table 18-1-B of the Uniform
Building Code (1994), creating substantial direct or indirect risks to life or property?
Less Than Significant Impact. Expansive soils are generally associated with soils, alluvium, and bedrock
formations that contain clay minerals susceptible to expansion under wetting conditions and contraction
under drying conditions. Depending upon the type and amount of clay present in a geologic deposit,
volume changes (shrink and swell) can cause severe damage to slabs, foundations, and concrete flatwork.48
Hanford, Vista Amargosa, and Tujunga-Soboba soils that underlie the City do not have high shrink-swell
potential and thus are not considered expansive. However, due to the granular (sandy) nature of the
alluvium in the flatter areas of the City, expansive clays would most likely be present in older alluvial,
bedrock formation soils in the hillside areas, and in sag-pond areas (e.g., the Los Angeles Arboretum and
Santa Anita Racetrack areas) caused by past impoundments along the northern side of the Raymond Fault.
While the Project Site is located in an area with potential to contain expansive soils, the Project would be
required to adhere to seismic safety design regulations required by the California Building Code, such as
those described above. Further, the City’s Building regulations provide appropriate building design criteria
needed to protect structural integrity of structures against soil expansion. Accordingly, with compliance
with required design criteria, the Project would not result in direct or indirect risks to life or property due
to expansive soils. Therefore, potential impacts related to expansive soils would be less than significant.
e) Would the project have soils incapable of adequately supporting the use of septic tanks
or alternative wastewater disposal systems where sewers are not available for the
disposal of wastewater?
No Impact. All wastewater generated by the Proposed Project would be discharged via a lateral
connection to an existing sanitary sewer infrastructure in Michillinda Avenue and Colorado Boulevard.
There would be no on-site wastewater disposal system. Therefore, no impact related to unstable soils
due to the use of septic tanks would occur.
f) Would the project directly or indirectly destroy a unique paleontological resource or site
or unique geologic feature?
Less Than Significant Impact with Mitigation Incorporated. Paleontological resources, as
defined by the Bureau of Land Management, U.S. Department of the Interior, are the physical remains
or other physical evidence of plants and animals preserved in soils and sedimentary rock formations.
The Project Site has been extensively disturbed in the past and is currently covered with a restaurant
structure and other improvements (such as outdoor parking areas). However, there would be some
potential for encountering vertebrate paleontological resources during grading activities for the
Proposed Project. To avoid the potential destruction of undiscovered paleontological resources,
Mitigation Measure GEO-1 would be imposed to ensure proper identification and treatment of
paleontological resources that may be discovered during grading. Therefore, with mitigation
incorporated, potentially significant impacts would be reduced to less than significant.
GEO-1 Paleontological Resource Monitor. If paleontological resources (fossils) are
discovered during Project grading, work shall be halted in that area until a qualified
paleontologist can be retained to assess the significance of the find. The Project

܆ ܆ ܈ ܆
Discussion
a) Would the project generate greenhouse gas emissions, either directly or indirectly, that
may have a significant impact on the environment?
Less Than Significant Impact. California is a substantial contributor of greenhouse gases (GHGs),
emitting over 440 million tons of carbon dioxide (CO 2) per year.49 Methane (CH4) is also an important
GHG that potentially contributes to global climate change. GHGs are global in their effect, which is
to increase Earth’s ability to absorb heat in the atmosphere. As primary GHGs have a long lifetime in
the atmosphere, accumulate over time, and are generally well-mixed, their impact on the atmosphere
is mostly independent of the point of emission.
The City of Arcadia has not adopted a numerical significance threshold for assessing impacts related
to GHG emissions. Similarly, SCAQMD, CARB, or any other State or regional agency has not yet
adopted a numerical significance threshold for assessing GHG emissions that is applicable to the
Project. Notwithstanding, for informational purposes, the following analysis calculates the amount of
GHG emissions that would be attributable to the Project using recommended air quality models, as
described below. The primary purpose of quantifying the Project’s GHG emissions is to satisfy CEQA
Guidelines Section 15064.4(a), which calls for a good-faith effort to describe and calculate emissions.
The estimated emissions inventory is also used to determine if there would be a reduction in the
Project’s incremental contribution of GHG emissions as a result of compliance with regulations and
requirements adopted to implement plans for the reduction or mitigation of GHG emissions.

However, the significance of the Project’s GHG emissions impacts is not based on the amount of
GHG emissions resulting from the Project.
Direct, Project-related GHG emissions include emissions from construction activities, area sources,
and mobile sources, while indirect, Project-related GHG emissions include emissions from electricity
consumption, water demand, and solid waste generation. Operational GHG estimations are based on
energy emissions from natural gas usage and automobile emissions. Table VIII-1 presents the
estimated CO2, N2O, and CH4 emissions of the Proposed Project. In accordance with SCAQMD
guidance, projected GHGs from construction have been quantified and amortized over 30 years
(representing the life of the Project), which are added to the annual average operation emissions.50 As
shown in Table VIII-1, the Project would result in a GHG emissions reduction of approximately
209.75 metric tons of carbon dioxide equivalent (MT CO2e) per year when compared to the existing
Coco’s Restaurant. This overall reduction in GHG emissions can be attributed to the decrease in total
daily vehicle trips associated with the development as compared with existing conditions.51 This
reduction in total daily vehicle trips is further discussed in Section XVII, Transportation/Traffic, of
this Initial Study.

Because the Proposed Project would result in a net reduction in overall Project-related emissions, the
Project would not generate GHG emissions that would have a significant impact on the environment.
Rather, the Project would represent a reduction in GHG emissions as compared to existing conditions.
Therefore, impacts would be less than significant.
b) Would the project conflict with an applicable plan, policy or regulation adopted for the
purpose of reducing the emissions of greenhouse gases?
Less Than Significant Impact. As described above, there is no applicable adopted or accepted
numerical threshold of significance for GHG emissions. Therefore, a methodology for evaluating the
Project’s impacts related to GHG emissions focuses on its consistency with Statewide, regional, and
local plans adopted for the purpose of reducing and/or mitigating GHG emissions. This evaluation
of consistency with such plans is the sole basis for determining the significance of the Project’s GHG-
related impacts on the environment.
2017 CARB Scoping Plan
The goal to reduce GHG emissions to 1990 levels by 2020 (Executive Order S-3-05) was codified by
the California legislature as the 2006 Global Warming Solutions Act (Assembly Bill [AB] 32).52 In
2008, CARB approved a Scoping Plan as required by AB 32, which was updated in 2017.53 This update
focuses on implementation of a 40 percent reduction in GHGs by 2030 compared to 1990 levels. To
achieve this, the 2017 Scoping Plan draws on a decade of successful programs that addresses the major
sources of climate-changing gases in every sector of the economy, such as clean cars and trucks,
renewable energy, reduction of pollutants such as hydrofluorocarbon refrigerants and methane, and
cleaner fuels. Achieving the 2030 target under the updated Scoping Plan will also spur the
transformation of the California economy and fix its course securely on achieving an 80 percent
reduction in GHG emissions by 2050, consistent with the global consensus of the scale of reductions
needed to stabilize atmospheric GHG concentrations at 450 ppm carbon dioxide equivalent, and
reduce the likelihood of catastrophic climate change.
Table VII-2 evaluates applicable reduction actions/strategies by emissions source category to
determine how the Project would be consistent with or exceed reduction actions/strategies outlined
in the 2017 Scoping Plan.

Project Consistency with the 2017 CARB Scoping Plan
Actions and Strategies Project Consistency Analysis
SB 350 Clean Energy and Pollution Reduction
Achieve a 50 percent RPS by 2030, with a doubling of energy
efficiency savings by 2030.
Consistent. The Project would not be an electrical
provider or delay the goals of Senate Bill (SB) 350.
Furthermore, the Project would utilize electricity from
Southern California Edison (SCE), which would be
required to comply with SB 350. As the Project would
use the electricity from SCE, the Project would be in
compliance with SB 350.
Low Carbon Fuel Standard (LCFS)
Increase stringency of carbon fuel standards; reduce the
carbon intensity of fuels by 18 percent by 2030, which is up
from 10 percent in 2020.
Consistent. Motor vehicles driven by the Proposed
Project’s employees, residents, and visitors would be
required to use LCFS-compliant fuels; thus, the Project
would be in compliance with this goal.
Mobile Source Strategy (Cleaner Technology and Fuels Scenario)
Maintain existing GHG standards of light- and heavy-duty
vehicles while adding an addition 4.2 million zero-emission
vehicles (ZEVs) on the road. Increase the number of ZEV
buses, delivery trucks, or other trucks.
Consistent. The Project would be required to comply
with the CALGreen Residential Mandatory Measure
4.106.4 Electric vehicle (EV) charging for new construction. As
such, the Project would support the use of ZEV vehicles
and would not conflict with the goals of the Mobile
Source Strategy.
Short-Lived Climate Pollutant (SLCP) Reduction Strategy
Reduce the GHG emissions of methane and
hydrofluorocarbons by 40 percent below the 2013 levels by
2030. Furthermore, reduce the emissions of black carbon
by 50 percent below the 2013 levels by the year 2030.
Consistent. The Project does not involve sources that
would emit large amounts of methane (refer to Table
VIII-1). Furthermore, the Project would comply with all
CARB and SCAQMD hydrofluorocarbon regulations.
As such, the Project would not conflict with the SLCP
reduction strategy.
SB 375 Sustainable Communities Strategies
Increase the stringency of the 2035 GHG emissions per
capita reduction target for MPOs.
Consistent. As shown in Table VIII-3, the Project
would be consistent with the SCAG 2016 RTP/SCS and
would not conflict with the goals of SB 375.
Source: California Air Resources Board, California’s 2017 Climate Change Scoping Plan, November 2017.
SCAG 2016-2040 RTP/SCS
The 2016-2040 RTP/SCS is expected to help California reach its GHG reduction goals, with reductions
in per capita transportation emissions of 9 percent by 2020 and 13 percent by 2035.54 Furthermore,
although there are no per capita GHG emission reduction targets for passenger vehicles set by CARB for
2040, the 2016-2040 RTP/SCS GHG emission reduction trajectory shows that more aggressive GHG
emission reductions are projected for 2040.55 At the regional level, the 2016-2040 RTP/SCS is an applicable
plan adopted for the purpose of reducing GHGs. In order to assess the Project’s consistency with the
2016-2040 RTP/SCS, Table VIII-3 evaluates the Project’s land use assumptions for consistency with
those included in the 2016-2040 RTP/SCS. Generally, Projects are considered consistent with the
provisions and general policies of applicable City and regional land use plans and regulations, such as
SCAG’s 2016-2040 RTP/SCS, if they are compatible with the general intent of the plans and would not

In summary, the plan consistency analyses provided above demonstrates that the Project complies
with the plans, policies, regulations, and GHG reduction actions/strategies outlined in the 2017 CARB
Scoping Plan and SCAG 2016-2040 RTP/SCS. Therefore, the Project would not conflict with any
applicable plan, policy, or regulation of an agency adopted for the purpose of reducing emissions of
GHGs. Furthermore, because the Project would result in a net reduction of GHG emissions and the
Project is consistent with the aforementioned plans, policies, and regulations, the Project’s incremental
increase in GHG emissions as described above would not result in a significant impact on the
environment. Therefore, Project-specific impacts with regard to consistency with climate change
programs and policies would be less than significant.

Discussion
a) Would the project create a significant hazard to the public or the environment through
the routine transport, use, or disposal of hazardous materials?
Less Than Significant Impact. Materials are generally considered hazardous if they are poisonous
(toxicity), can be ignited by open flame (ignitability), corrode other materials (corrosivity), or react
violently, explode, or generate vapors when mixed with water (reactivity). The term “hazardous
material” is defined in California Health and Safety Code as any material that, because of its quantity,
concentration, or physical or chemical characteristics, poses a significant present or potential hazard
to human health and safety or to the environment if released into the workplace or the environment
(Section 25501(n)(1)). The code additionally states that a hazardous material becomes a hazardous
waste once it is abandoned, discarded, or recycled.
The transportation, use, and disposal of hazardous materials, as well as the potential release of
hazardous materials to the environment, are closely regulated through State and federal laws. Such
laws include those incorporated into the California Health and Safety Code, such as the California
Hazardous Materials Release Response Plans and Inventory law and the California Hazardous Waste
Control law, as well as other regulations governing hazardous waste promulgated by State and federal
agencies, such as the Los Angeles County Department of Public Works, California Department of
Toxic Substances Control (DTSC), California Division of Occupational Safety and Health, the
Regional Water Quality Control Board, and the USEPA.
Artis Senior Housing Project
Draft Initial Study Page 58 April 2020
The Proposed Project would include a memory care facility, along with associated surface parking and
landscaping areas. Maintenance of the facility and grounds by employees and contractors would likely
involve the routine transport, use, and disposal of minor quantities of typical household hazardous
materials, such as cleaning products, solvents, adhesives, refrigerants, paints, other chemical materials
used in building maintenance, small amounts of oil and fuels from internal combustion engines,
pesticides and herbicides, sharp or used needles, and electronic waste. This level of hazardous materials
use would be typical for institutional uses and has not been identified as a significant threat to the
environment. Regulations, such as those mentioned above, strictly regulate the use, transportation,
and disposal of hazardous waste; they include training for employees in how to properly handle and
dispose of hazardous materials, as well as filing floor plans with the Los Angeles County Fire
Department showing locations of hazardous material storage.
Given the age of the existing restaurant building on-site (constructed in the 1970s), there is potential
for the building to contain asbestos-containing materials (ACM) and/or lead-based paint (LBP). If
ACM or LBP is found during the demolition phase of construction, the applicant would be required
to comply with 40 CFR Part 61, Cal OSHA rule 1529, and South Coast Air Quality Management
District Rule 1403 when it comes to identification, removal, handling, and disposal of ACM. The
applicant must also comply with requirements detailed in 24 CFR Part 35, Cal OSHA rule 1532.1, and
40 CFR Part 745 regarding evaluation, testing, and reducing lead-based paint hazards. Compliance
with these regulations would ensure that Project-related contamination would be effectively disposed
of during the demolition phase and would, therefore, have no effect on the health and safety of area
residents.
Based on the type of land use proposed, the relatively minor anticipated level of use, storage, and
disposal of hazardous materials, and the requirement to comply with various State and federal laws
regulating hazardous materials, the Project would not result in a significant impact involving the
routine transport, use, or disposal of hazardous materials. Therefore, potential impacts related to
hazardous materials would be less than significant.
b) Would the project create a significant hazard to the public or the environment through
reasonably foreseeable upset and accident conditions involving the release of hazardous
materials into the environment?
Less Than Significant Impact. Locations known to contain toxic substances and contamination are
identified using data from DTSC. The Project Site is not identified as a clean-up site or located within
one-half mile of a clean-up site listed in the DTSC EnviroStor database.56 However, the GeoTracker
database, maintained by the California State Water Resources Control Board (SWRCB), identified five
clean-up sites within one-half mile of the Project Site. These clean-up sites are located at 3706 Foothill
Boulevard (two clean-up sites at this address), 3698 Colorado Boulevard, 4000 Foothill Boulevard,
and 3880 Colorado Boulevard and are all leaking underground storage tank (LUST) clean-up sites.
According to the SWRCB, each of these clean-up sites was addressing soil contamination associated
with leaking gasoline tanks. Each site has been cleaned up (as of 2008), and each of the individual
cases closed. Because Project-related ground disturbance would be limited to the Project Site, which
is not listed on hazardous waste disposal or clean-up databases maintained by the State, the Project
56 California Department of Toxic Substances Control (DTSC), EnviroStor Database search, accessed October 21,
2019.
Artis Senior Housing Project
Draft Initial Study Page 59 April 2020
would not result in reasonably foreseeable upset of existing contamination located at the clean-up sites
in the Project vicinity.
Construction activities may also include refueling and minor maintenance of construction equipment
on-site, which could lead to minor fuel and oil spills; however, as described in the response to Checklist
Question X.a, below, a variety of routine construction control measures would be incorporated,
including spill prevention/containment, sedimentation and erosion controls, and irrigation controls,
to prevent conditions that would release hazardous materials into the environment during Project
construction.
Additionally, as stated above, operation of the proposed institutional facility would not result in
substantial use, transport, or disposal of hazardous materials. Further, any such use, transport, and
disposal of hazardous materials would be strictly regulated by State and federal laws. As such, there
would not be a significant hazard to the public involving the accidental release of hazardous materials
into the environment during Project operation.
Therefore, the Proposed Project would not result in any reasonably foreseeable upset and accident
conditions involving the release of hazardous materials into the environment, and impacts would be
less than significant.
c) Would the project emit hazardous emissions or handle hazardous or acutely hazardous
materials, substances, or waste within one-quarter mile of an existing or proposed
school?
No Impact. The nearest school to the Project Site is Hugo Reid Primary School, which is located
approximately one-half mile south of the Project Site (located at 1153 de Anza Place).57 Therefore,
there are no existing or proposed schools within one-quarter mile of the Project Site, and no impact
would occur.
d) Would the project be located on a site which is included on a list of hazardous materials
sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it
create a significant hazard to the public or the environment?
No Impact. The Project Site is not included on the Cortese list, which is the list of sites compiled by
DTSC under Government Code Section 65962.5. As such, the Project Site is not included on DTSC’s
list of hazardous waste facilities subject to corrective action pursuant to Section 25187.5 of the Health
and Safety Code; land designated as hazardous waste property or border zone property pursuant to
Article 11; information received regarding waste disposals on public land; all sites listed pursuant to
Section 25356 of the Health and Safety Code; or all sites included in the Abandoned Site Assessment
program.58,59 As such, the Proposed Project would not create a significant hazard to the public or the
environment, and no impact would occur.

e) For a project located within an airport land use plan or, where such a plan has not been
adopted, within two miles of a public airport or public use airport, would the project result
in a safety hazard or excessive noise for people residing or working in the project area?
No Impact. The nearest airport to the Project Site is the San Gabriel Airport (also known as El Monte
Airport), which is approximately 4.5 miles southeast. Therefore, the Project Site is not within 2 miles
of a public airport and would not result in a safety hazard or excessive noise for people residing or
working in the Project area, and no impact would occur.
f) Would the project impair implementation of or physically interfere with an adopted
emergency response plan or emergency evacuation plan?
Less Than Significant Impact. The Project Site is currently occupied by a restaurant building, which
is currently receiving police, fire, and paramedic services provided by the City of Arcadia. Access to
the Project Site is currently available on Michillinda Avenue and Colorado Boulevard. The Proposed
Project would have one ingress and egress point onto Colorado Boulevard, with available right-turn
and left-turn egress options. Project inhabitants would have access to major thoroughfares such as
Michillinda Avenue, I-210, and Foothill Boulevard (identified as a Principal Travel Corridor by the
City’s General Plan) during an emergency evacuation. Further, the Proposed Project would be
consistent with the General Plan land use and zoning designations. Therefore, development of the
Project Site as proposed would not impair implementation of an adopted emergency response plan or
evacuation plan. As such, potential impacts related to emergency response or evacuation would be
less than significant.
g) Would the project expose people or structures, either directly or indirectly, to a significant
risk of loss, injury or death involving wildland fires?
No Impact. The Project Site is not located within a Very High Fire Hazard Severity Zone, as
identified by the California Department of Forestry and Fire Protection.60,61 Very High Fire Hazard
Severity Zones in the City of Arcadia are concentrated on the northeast side of the City, in the foothills
near the Cities of Monrovia and Sierra Madre, approximately 2.1 miles northeast of the Project Site.
The Project Site is in a fully urbanized area with an urban street network, a fully pressurized water
system, and managed landscaping limited to decorative trees and shrubs. The Project Site does not
include and is not surrounded by wildland areas, such as low-density hillside areas with large quantities
of uncultivated, combustible plants. Therefore, the Project would not expose people or structures,
either directly or indirectly, to a significant risk of loss, injury, or death involving wildland fires. As
such, no impact related to wildland fire would occur.

Discussion
a) Would the project violate any water quality standards or waste discharge requirements
or otherwise substantially degrade surface or ground water quality?
Less Than Significant Impact. The Los Angeles Regional Water Quality Control Board
(LARWQCB) prepares and maintains a basin plan which identifies narrative and numerical water
quality objectives to protect all beneficial uses of the waters of that region. The basin plan strives to
achieve the identified water quality objectives through implementation of Waste Discharge
Requirements (WDRs) and by employing three strategies for addressing water quality issues: control
of point source pollutants, control of nonpoint source pollutants, and remediation of existing
Artis Senior Housing Project
Draft Initial Study Page 62 April 2020
contamination. The project site is located in the Los Angeles region and is, therefore, covered under
the Basin Plan for the Coastal Watersheds of Los Angeles and Ventura Counties (Basin Plan).
Point sources of pollutants are well-defined locations at which pollutants flow into water bodies
(discharges from wastewater treatment plants and industrial sources, for example). These sources are
controlled through regulatory systems including permitting under California’s WDRs and the NPDES
program; permits are issued by the appropriate RWQCB and may set discharge limitations or other
discharge provisions. According to the Basin Plan, nonpoint sources of pollutants are typically derived
from project site runoff caused by rain or irrigation and have been classified by the USEPA into one
of the following categories: agriculture, urban runoff, construction, hydromodification, resource
extraction, silviculture, and land disposal.
The Project could have both short- and long-term impacts on water quality. Short-term impacts would
occur during the construction phase of the Project, when the pollutants of greatest concern are
sediment, which may run off the Project site due to site grading or other site preparation activities,
and hydrocarbon or fossil fuel remnants from the construction equipment. In addition, on-site
watering activities to reduce airborne dust could contribute to pollutant loading in surface runoff.
However, construction runoff is regulated by the NPDES Construction General Permit, which
requires identification of a variety of water quality control BMPs to be specified on construction plans
and implemented throughout construction. Measures are required to keep stormwater out of
construction zones; conduct regular site maintenance and “good housekeeping practices” to prevent,
minimize, and dispose of solid and liquid wastes; capture and control any site runoff so that water
pollutants don’t enter storm drains; and have response procedures in place in the event of accidental
spills of water contaminants. This permit applies to all construction which disturbs an area of at least
1 acre and is administered by the relevant RWQCB. As stated in response to Checklist Question VII.b
of this Initial Study, the City would require the preparation of a Stormwater Pollution Prevention Plan
for the Proposed Project, which would establish erosion and sedimentation controls, such as methods
to minimize the footprint of the disturbed area, controls to prevent tracking off-site, spill prevention,
non-stormwater controls (i.e., vehicle washing), and methods to protect native vegetation and trees.
Further, the City would require a NPDES Construction General Permit for discharge of stormwater
associated with Project construction activities. Through these existing, mandatory regulatory
compliance measures, potential water quality impacts during construction would be avoided or
reduced to less than significant levels and would avoid conflicts with water quality standards
established by the LARWQCB.
Long-term impacts would result from operation of the completed Project. Such impacts could result
from stormwater runoff of impervious surfaces on the Project site. The Project is considered a
Planning Priority Project as it is a development equal to or greater than 1 acre in size that adds more
than 10,000 square feet of impervious surface area. As such, the Project would require a Low Impact
Development Plan (LID Plan), which would be reviewed and approved through the City’s plan check
process, to comply with the following requirements:62

Minimize hydromodification impacts to natural drainage systems.
When, as determined by the City, 100 percent on-site retention of the SWQDv is technically
infeasible, the infeasibility shall be demonstrated in the submitted LID plan.
If partial or complete on-site retention is technically infeasible, the Project Site may biofiltrate 1.5
times the portion of the remaining SWQDv that is not reliably retained on-site.
BMPs required by the City’s LID ordinance include ensuring sidewalks fronting the Project Site are
clear of dirt or litter; cleaning parking lots with 25 or more spaces as frequently and thoroughly as
practicable; diverting surface and roof flows to landscaped areas before discharge; and treating any
portion of the SWQDv that cannot be retained or biofiltered on-site in order to reduce pollutant
loading. Therefore, with conformance to the City’s LID requirements and incorporation of required
construction and post-construction BMPs, the Project would not result in the violation of any water
quality standards or WDRs, and impacts would be less than significant.
b) Would the project substantially decrease groundwater supplies or interfere substantially
with groundwater recharge such that the project may impede sustainable groundwater
management of the basin?
Less Than Significant Impact. The City is a retail water supplier that serves the majority of its
residents. In 2016, the City prepared the most recent Urban Water Management Plan (UWMP) in
cooperation with other water-serving agencies in the surrounding region. The City is a subagency of
the Upper San Gabriel Valley Municipal Water District (Upper District), a wholesale water agency.
The UWMP states that the City currently derives its water supply from groundwater wells that produce
water from two groundwater basins: the Main San Gabriel Basin (the City’s main groundwater source)
and the Raymond Basin. In the 2014-2015 fiscal year, the City pumped a total of 12,010 acre-feet from
the Main Basin and 3,316 acre-feet from the Raymond Basin.63 Further, the City can purchase
imported water from the Metropolitan Water District of Southern California (MWD); however, the
City does not typically use this alternative (the last time water was imported was in the 2009-2010
fiscal year) because the City’s groundwater supplies are sufficient to meet water demands.64 The City
owns and operates seven active groundwater wells in the Main Basin, with a collective capacity of
15,200 gallons per minute (gpm). Additionally, there are seven groundwater wells in the Raymond
Basin, with a collective capacity of 4,300 gpm.65 The UWMP concluded that based on current
management practices, including reduced pumping in the Raymond Basin, the City would be able to
rely on the Main Basin, the Raymond Basin, and imported water for adequate supply for 20 years (as
of publication of the UWMP in 2016), under single-year and multiple-year drought scenarios.
There are no groundwater wells on the Project Site and none are proposed. Further, the Proposed
Project would not involve a General Plan amendment or zone change. The City’s UWMP has

accounted for future water consumption of existing and planned land uses, such as the Proposed
Project.
Operation of the Proposed Project would not interfere with groundwater recharge. The Project Site
is located in an urbanized area and is currently developed with a restaurant building and a surface
parking lot. The Proposed Project would replace these existing improvements with an approximately
44,000-square-foot assisted living and memory care facility surrounded by surface parking, drive aisles,
outdoor walking paths and community areas, and managed landscaping. As such, the Proposed Project
would reduce, but not substantially change, the amount of impervious surface area on-site to affect
groundwater levels beneath the Project Site. If groundwater levels were to be affected, the effect would
be minimal and likely beneficial given the Project’s reduction in overall impervious surfaces as
compared with existing conditions. Therefore, the Project would not substantially deplete
groundwater supplies or interfere with groundwater recharge such that there would be a net deficit in
aquifer volume or a lowering of the local groundwater table level. Impacts to groundwater would be
less than significant.
c.i) Would the project substantially alter the existing drainage pattern of the site or area,
including through the alteration of the course of a stream or river or through the addition
of impervious surfaces, in a manner which would result in substantial erosion or siltation
on- or off-site?
Less Than Significant Impact. The Project Site is fully developed and landscaped and does not
contain any natural drainage courses. There is also no historical evidence of localized ponding or
flooding on the Project Site. Because the Project Site is currently fully developed, the Proposed Project
would not result in a substantial alteration of the existing drainage pattern, as the Proposed Project
would continue to discharge excess stormwater into the City’s storm sewer system.
Construction and operation of the Proposed Project could result in some erosion or siltation on- or
off-site. As stated in the response to Checklist Question VII.b of this Initial Study, erosion of
uncovered soils during construction activities would be prevented by complying with the NPDES
Construction General Permit requirements, which require construction activities to incorporate BMPs
to prevent erosion off-site. Additionally, because the Proposed Site is greater than 1 acre, the City
requires the preparation of a Stormwater Pollution Prevention Plan, which would establish erosion
and sedimentation controls. Otherwise, the operation of the Proposed Project would result in almost
the entire site covered in either impervious surfaces, such as the building, surrounding parking areas,
outdoor structures (i.e., outdoor gathering spaces, refuse and generator enclosures, and storage shed),
and concrete walkways, as well as managed landscaped areas. Because almost the entire site would be
covered by either impervious surfaces or managed gardens/turf areas, there would be very little
potential for erosion during long-term operation of the Project.
Therefore, the Project would not substantially alter the existing drainage pattern of the Project Site or
area in a manner that would result in erosion or siltation, on- or off-site, and impacts related to erosion
and siltation would be less than significant.

c.ii) Would the project substantially alter the existing drainage pattern of the site or area,
including through the alteration of the course of a stream or river or through the addition
of impervious surfaces, in a manner which would substantially increase the rate or
amount of surface runoff in a manner which would result in flooding on- or off-site?
Less Than Significant Impact. As stated in response to Checklist Question X.c.i, the existing,
relatively flat Project Site is fully developed with a restaurant building and an impervious, surface
parking lot. Therefore, the Proposed Project, which would include a slight reduction in impervious
surfaces due to the increase in landscaped areas, would not result in a substantial alteration of the
existing drainage pattern of the Project Site. Because the Project Site is not located within a Federal
Emergency Management Agency (FEMA) Flood Hazard Zone (the Project Site is located in a Zone
X, Area of Minimal Flood Hazard), there is no evidence that the site or the immediately surrounding
area is subject to flooding.66 Therefore, potential impacts of the Proposed Project on local drainage
and flooding would be less than significant.
c.iii) Would the project substantially alter the existing drainage pattern of the site or area,
including through the alteration of the course of a stream or river or through the addition
of impervious surfaces, in a manner which would create or contribute runoff water which
would exceed the capacity of existing or planned stormwater drainage systems or provide
substantial additional sources of polluted runoff?
Less Than Significant Impact. See the responses to Thresholds X.c.i and X.c.ii, above. The existing,
relatively flat Project Site is fully developed with a restaurant building and an impervious, surface
parking lot. Therefore, the Proposed Project, which would include a slight reduction in impervious
surfaces, would not result in a substantial alteration of the existing drainage pattern of the Project Site.
As the Proposed Project would increase the total amount of pervious landscape areas on the Project
Site, it would not contribute additional runoff as compared with existing conditions. Further, the
Project would be required to develop a LID Plan, which would retain stormwater runoff on-site for
the SWQDv defined as the runoff from the 85th percentile 24-hour runoff event. Further, the SWPPP
discussed above would prevent discharge of sediment or other water pollution commonly generated
by Project construction. Therefore, the Proposed Project would not alter the existing drainage pattern
of the site or area in a manner which would create or contribute runoff water that would exceed the
capacity of existing or planned stormwater drainage systems. As such, potential impacts of the
Proposed Project on stormwater drainage systems would be less than significant.
c.iv) Would the project substantially alter the existing drainage pattern of the site or area,
including through the alteration of the course of a stream or river or through the addition
of impervious surfaces, in a manner which would impede or redirect flood flows?
Less Than Significant Impact. As stated above, the Project Site is located within a Zone X, Area
of Minimal Flood Hazard, according to the FEMA Flood Insurance Rate Map for the area. Further,
because the project would not substantially alter the existing drainage pattern of the Project Site, the
Project would not alter the site or area in a manner which would impede or redirect flood flows, and
impacts would be less than significant.

d) Would the project in flood hazard, tsunami, or seiche zones, risk release of pollutants due
to project inundation?
No Impact. A seiche is the sudden oscillation of water that occurs in an enclosed, landlocked body
of water due to wind, earthquake, or other factors. There are no reservoirs or other bodies of water
near the Project Site that could result in seiche impacts to the Project; therefore, the Project would
not place structures in areas subject to inundation by seiche.
A tsunami is an unusually large wave or set of waves that is triggered in most cases by a seaquake or
an underwater volcanic eruption. The Project Site is located more than 25 miles away from the Pacific
Ocean. Given this distance, the Project would not place structures in areas subject to inundation by
tsunami.
Finally, as stated above, the Project Site is located within a Zone X, Area of Minimal Flood Hazard,
according to the FEMA Flood Insurance Rate Map for the area. However, the Project Site is located
within a designated inundation area for the Morris S. Jones Reservoir. As stated in the General Plan
Safety Element, the dams above Arcadia are regulated and monitored for structural safety by the
California Department of Water Resources, in accordance with Division 3 of the California State
Water Code. Such regulation reduces the chance of catastrophic failure and inundation of downstream
areas, such as the Project Site.67 Water quality controls on-site, such as maintenance of landscape areas,
and proper storage of any hazardous materials would prevent the release of pollutants in the unlikely
event that the Project Site would be inundated by catastrophic dam failure. Therefore, the Project Site
is not located within a flood hazard, tsunami, or seiche zone and would have no impact as it relates to
the release of pollutants due to flood-, tsunami-, or seiche-related inundation.
e) Would the project conflict with or obstruct implementation of a water quality control plan
or sustainable groundwater management plan?
Less Than Significant Impact. As stated above, the City of Arcadia’s 2015 UWMP states that the
Main Basin groundwater supply is the City’s main source of water, accounting for approximately 78
percent of the City’s water supply. The Main Basin Watermaster, an organization created in the 1970s
to resolve water demand issues that arose in the San Gabriel Basin, is tasked with general management
of the groundwater basin, including addressing volatile organic compound (VOC) contamination that
was discovered in the 1970s and 1980s. The Watermaster’s Five Year Water Quality and Supply Plan
is an annually updated document that projects both water supply and water quality. In the 2019 plan
update (2019 Supply Plan), the Watermaster reports that total groundwater production for the Main
Basin in fiscal year 2018-2019 was 189,100 acre-feet, which is lower than the 10-year average of
203,000 acre-feet.68 While groundwater production has experienced a general long-term increase,
corresponding to a population increase in the Main Basin’s service area, a gradual decrease in
production since the late 2000s is likely resulting from increased water conservation practices by
consumers. The 2019 Supply Plan shows that 2018-2019 fiscal year groundwater production in the
City of Arcadia was approximately 10,774 acre-feet and projects groundwater demands to fluctuate
between 9,565 and 10,953 acre-feet between the 2019-2020 and the 2023-2024 fiscal years.69 Further,
the groundwater elevations at all seven of the Main Basin groundwater wells in the City of Arcadia are
projected to increase between 2018 and 2024, indicating a projected increase in water supplies.70 Lastly,

the 2019 Supply Plan details how the Watermaster coordinates with local and regional agencies to
monitor groundwater quality and potential groundwater well contamination points.
Because the Proposed Project would not result in a substantial increase in potable water demand, and
because it would not involve the use, disposal, or storage of hazardous chemicals that could impact
water quality, the Proposed Project would not interfere with the Main Basin Watermaster’s 2019
Supply Plan, and impacts would be less than significant.

܆ ܆ ܈ ܆
Discussion
a) Would the project physically divide an established community?
No Impact. As shown in Figure A-13, Aerial View of the Project Site and Surroundings, of this
Initial Study, the Project Site is located within a fully urbanized area where the built environment
consists of single-family residential uses to the east and south, commercial uses to the west, and I-210
to the north. The physical arrangement of the surrounding private lots, streets, and utility
infrastructure has been established for many years. The Proposed Project would use an existing public
street (Colorado Boulevard) for access to the senior living facility and would connect to existing
utilities in adjacent streets. The Proposed Project would not result in the construction of a linear
feature, such as railroad tracks, a flood control channel, or a major roadway, or the removal of a means
of access that would result in a physical division of an established community. No physical alterations
to any land use or the physical structure of this part of the City of Arcadia are proposed outside of the
Project Site. Therefore, the Proposed Project would not physically divide an established community
and there would be no impact.
b) Would the project cause a significant environmental impact due to a conflict with any
land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an
environmental effect?
Less Than Significant Impact. As stated in the Project Description of this Initial Study, the existing
General Plan land use designation for the Project Site is Commercial, with a corresponding zoning of
C-G, General Commercial. A residential care facility is allowed within the C-G, General Commercial
with an approved CUP.71 The Project Site is also included within two existing overlay zones, the
Architectural Design Overlay Zone and the Automobile Parking Overlay Zone. The Architectural
Design Overlay Zone states that various building design characteristics (such as building exterior
materials, roof pitch, window size, landscaping, and automobile parking area) shall be subject to
71 City of Arcadia, Development Code Section 9102.03.020.

Planning Commission review and approval. Further, the Architectural Design Overlay Zone states
that only one free-standing sign shall be permitted and located within 100 feet of the northern and
western property lines, the maximum building height shall not reach 30 feet above ground level, and
no structure erected or permitted shall exceed 19,500 square feet of ground floor area.72,73 The
Automobile Parking overlay zone states that the overlay area shall be limited to ground level parking
only.
As part of the Project, the Applicant has requested a zone change to remove these two overlay zones.
Regardless, the Project would not represent a substantial change in urban form over existing
conditions. More specifically, the eastern portion of the Project Site, which is currently included within
the Automobile Parking Overlay Zone, would remain as surface parking under the Proposed Project
conditions. The southern portion of the Project Site, which is also included within the Automobile
Parking Overlay Zone, would include developed open space with no above-ground structures except
a small storage shed in the southeastern corner of the Project Site and an eight-foot-high decorative
fence around the perimeter of the open space area. Further, the majority of the proposed memory
care facility located on the northeastern portion of the Project Site would be limited to 30 feet in
height, consistent with the existing Architectural Design Overlay Zone, with only the north-central
portion of the facility extending to 37.5 feet in height (with an additional 2.5-foot-high decorative
cupola). With the removal of these two overlay zones, development on the Project Site would be
regulated by the development standards of the underlying General Commercial (C-G) zone, such as
regulations regarding building height and setback distance from residential land uses. These
development standards include, but are not limited to, a 40-foot building height maximum and a 20-
foot building setback when abutting residential uses. Based on the Project details included in the
Project Description, the Project would be consistent with the development standards and regulation
of the underlying General Commercial (C-G) zone upon approval of a CUP. Further, the Arcadia
General Plan Parks, Recreation, and Community Resources Element does not identify any land use
restrictions for the Project Site that would require conservation of the Project Site for purposes of
protecting wildlife habitat or other natural resources. There are no policies in the Safety Element that
establish land use restrictions for the Project Site pertaining to avoidance of environmental hazards
on or near the Project Site. The Project Site is not within an area where special land use policies or
zoning standards have been created for the purpose of avoiding or mitigating environmental effects,
nor is it within a local coastal program. As such, the Project would not conflict with an applicable land
use plan, policy, or regulation established for the purpose of avoiding or mitigating an environmental
effect, and impacts related to land use and planning would be less than significant.

܆ ܆ ܆ ܈
Discussion
a) Would the project result in the loss of availability of a known mineral resource that would
be of value to the region and the residents of the state?
No Impact. The Project Site is located within a fully urbanized area and is currently developed with
a restaurant building and a surface parking lot. The City’s General Plan EIR Mineral Resources Section
states that there are no oil, gas, or geothermal resources within the City of Arcadia.74 The only oil well
in the City of Arcadia is owned by the Vosburgh Oil Corporation and is plugged and abandoned.75
Because this well is abandoned and located approximately 2.5 miles southeast of the Project Site, the
Project Site is not located within any known oil, gas, or geothermal resource areas, and the Project Site
is already developed with a non-extraction use, the Project would not result in the loss of availability
of a known mineral resource that would be of regional or Statewide value. Therefore, no impact to
mineral resources would occur.
b) Would the project result in the loss of availability of a locally-important mineral resource
recovery site delineated on a local general plan, specific plan or other land use plan?
No Impact. As stated above, the Project Site is located in a fully urbanized area and is currently
developed with a restaurant building and a surface parking lot. The City’s General Plan EIR Mineral
Resources section states that the Project Site is located within a Mineral Resource Zone-3 (MRZ-3)
area, which is composed of the northwestern and southern portions of the City where the available
data which would be used to determine the significance of mineral deposits are unavailable.76 Other
areas of the City, including areas along the Sierra Madre Wash, Santa Anita Wash, and the San Gabriel
River, are designated as MRZ-2 because significant mineral deposits may be present and development
in such areas should be controlled. The City’s General Plan EIR identifies four sites within the City
that are located within MRZ-2 zones and remain undeveloped at the time of the General Plan update
in 2010. These are the Los Angeles County flood control wash and infiltration basin, the former
Rodeffer sand and gravel excavation site, the Peck Road Spreading Basins/Water Conservation Park,
and the Livingston-Graham sand and gravel excavation site. The Project Site is not located within or
adjacent to these MRZ-2 locations. Therefore, the Proposed Project would not result in the loss of

Discussion
a) Would the project result in generation of a substantial temporary or permanent increase
in ambient noise levels in the vicinity of the project in excess of standards established in
the local general plan or noise ordinance, or applicable standards of other agencies?
Less Than Significant Impact with Mitigation Incorporated. The Project vicinity consists of
residential and commercial uses. The primary sources of stationary noise in the Project vicinity are
urban activities (e.g., mechanical equipment, HVAC units, and parking areas). The noise associated
with these sources may represent a single-event noise occurrence, or short-term or long-
term/continuous noise. The majority of existing noise in the Project vicinity is generated by vehicular
sources along I-210 and Colorado Boulevard. According to the Arcadia General Plan, traffic noise
levels along I-210 and Colorado Boulevard range from 60 to 85 dBA CNEL. Additionally, aircraft
overflights and trains are a source of noise in the City of Arcadia.
To quantify existing ambient noise levels in the Project vicinity, three noise measurements were taken
on December 11, 2019 (see Table XIII-1). The noise measurement sites were representative of typical
existing noise exposure within and immediately adjacent to the Project Site. Ten-minute measurements
were taken between 10:00 a.m. and 11:30 a.m. Short-term (Leq) measurements are considered
representative of the noise levels throughout the day.

Construction
Construction of the Proposed Project would occur over approximately 19 months and would include
demolition, grading, paving, building construction, and architectural coating. Ground-borne noise and
other types of construction-related noise impacts would typically occur during the grading phase. This
phase of construction has the potential to create the highest levels of noise. Typical noise levels
generated by construction equipment are shown in Table XIII-2. It should be noted that the noise
levels identified in Table XIII-2 are maximum sound levels (Lmax), which are the highest individual
sounds occurring at an individual time period. Operating cycles for these types of construction
equipment may involve one or two minutes of full power operation followed by three to four minutes
at lower power settings. Other primary sources of acoustical disturbance would be due to random
incidents, which would last less than one minute (such as dropping large pieces of equipment or the
hydraulic movement of machinery lifts).

Pursuant to Arcadia Municipal Code Article IV, Chapter 2, Disorderly Conduct, Nuisances, Etc., construction
activities may only occur between the hours of 7:00 a.m. and 6:00 p.m. Monday through Friday, and
between 8:00 a.m. and 5:00 p.m. on Saturday. Construction activities are prohibited on Sundays and
holidays. These permitted hours of construction are included in the Arcadia Municipal Code in
recognition that construction activities undertaken during daytime hours are a typical part of living in
an urban environment and do not cause a significant disruption. The potential for construction-related
noise to affect nearby residential receptors would depend on the location and proximity of
construction activities to these receptors. Construction would occur throughout the Project Site and
would not be concentrated or confined in the area directly adjacent to sensitive receptors. Therefore,
construction noise would be acoustically dispersed throughout the Project Site and not concentrated
in one area near adjacent sensitive uses. It should be noted that the noise levels depicted in Table
XIII-2 are maximum noise levels, which would occur sporadically when construction equipment is
operated in proximity to sensitive receptors.
The closest existing sensitive receptors are residents adjoining (i.e., approximately 10 feet) the Project
Site to the east and south. As indicated in Table XIII-2, typical construction noise levels would range
from approximately 91 to 104 dBA at this distance. Although construction noise is allowed during the
City’s allowable construction hours and is not considered to be a significant impact during those hours,
the Project could expose adjoining residential uses to temporary high noise levels (91 to 104 dBA)
during construction activities. Consequently, Mitigation Measure NOI-1 is recommended to reduce
short-term construction noise impacts through noise reduction methods. Mitigation Measure
NOI-1 requires all construction equipment to be equipped with properly operating and maintained
mufflers, stationary construction equipment to be located such that emitted noise is directed away
from the nearest noise sensitive receptors, and equipment staging is in areas farthest away from
sensitive receptors. Implementation of Mitigation Measure NOI-1 would ensure that construction
noise impacts at nearby sensitive receptors do not interfere with normal residential activities.
Therefore, with implementation of Mitigation Measure NOI-1, noise impact from construction
activities would be considered less than significant.
Operation
Mobile Noise
The existing Coco’s Restaurant generates approximately 582 trips per day, and the Proposed Project
would generate approximately 208 trips per day.77 Therefore, the Proposed Project would generate a
net decrease of approximately 374 daily trips when compared to the existing use. As such, the Project’s
trip generation would reduce existing traffic volumes and, in turn, reduce traffic noise levels along
local roadways. Therefore, Project-related traffic noise would be less than significant.
In addition to the mobile sources of noise identified above, the Project vicinity may also be impacted
by noise generated by emergency ambulance visits to the Project Site. While there may be a perception
that the proposed use would result in a greater number of ambulance visits to the area than the existing
commercial use, it is not possible and highly speculative to predict medical emergencies that require
visits from emergency vehicles. Ambulances traveling to and from the Project Site would likely use
high-volume transit corridors, such as Colorado Boulevard and Michillinda Avenue, to access the
Project Site, rather than passing through the residential neighborhoods to the east and south. Further,
the decision to use a siren and lights is made by the vehicle driver and is dependent upon traffic
77 Michael Baker International, Artis Senior Assisted Living Facility Trip Generation Analysis, December 17, 2019.
Artis Senior Housing Project
Draft Initial Study Page 73 April 2020
conditions and the welfare of the patient. As such, emergency response vehicles may not engage the
siren in every instance and would likely turn off the siren upon arriving at the facility. Thus, because
an ambulance siren may not be engaged in every emergency response situation, and because a siren
would likely be turned off upon arrival, noise impacts resulting from ambulance visits to the Project
Site are anticipated to be infrequent and short-lived in nature. Additionally, the proposed memory care
facility would employ medical staff who would be able to address non-life-threatening medical
emergencies, such as minor injuries and falls, thus reducing the number of visits from rapid-response
emergency vehicles. Regular trips by Project residents to health care facilities would be accommodated
through family members or other non-emergency medical transport services, none of which would be
equipped with sirens. Finally, Arcadia Municipal Code Section 4610.1(I) exempts emergency vehicles
from the restrictions placed on sound amplifying equipment. Therefore, Project-related ambulance
noise associated with the Project would be less than significant.
Stationary Noise
Stationary noise sources associated with the Proposed Project would include mechanical equipment,
slow-moving trucks, and parking activities. These noise sources are typically intermittent and short in
duration and would be comparable to existing sources of noise experienced in the Project vicinity.
Mechanical Equipment
Typically, mechanical equipment can result in noise levels of approximately 55 dBA at 50 feet from
the source. Mechanical equipment (e.g., HVAC units and emergency generators) for the Project would
be located in fully enclosed spaces throughout the proposed senior living facility. Therefore, the
Project would not place mechanical equipment near sensitive receptors (i.e., existing residences
adjoining the Project Site to the east and south). As such, noise from mechanical equipment would
not be perceptible at the closest sensitive receptors. Impacts from mechanical equipment would be
less than significant.
Slow-Moving Trucks
The Proposed Project may involve occasional deliveries and trash/recycling pickups from slow-
moving trucks. Typically, a medium two-axle delivery truck can generate a maximum noise level of 75
dBA at a distance of 50 feet.78 This maximum noise level is assumed to be generated by a truck that is
operated by an experienced “reasonable” driver with typically applied accelerations. Noise associated
with deliveries and trash/recycling pickups would be consistent with the existing noise environment,
as these activities already occur at the commercial uses in the surrounding area. Additionally, slow-
moving truck noise would be intermittent, short in duration, and would not generate excessive noise
levels over an extended period of time. Therefore, impacts resulting from truck delivery activities
would be less than significant.
Parking Areas
Traffic associated with senior living facility parking areas is typically not of sufficient volume to exceed
community noise standards, which are based on a time-averaged scale such as the Day-Night Sound
Level (Ldn) scale. However, the instantaneous maximum sound levels generated by a car door
slamming, engine starting up, and car pass-bys may be an annoyance to adjacent noise-sensitive
receptors. Estimates of the maximum noise levels associated with some parking activities are presented
78 Measurements taken by Michael Baker International in 2006.
Artis Senior Housing Project
Draft Initial Study Page 74 April 2020
in Table XIII-3. The Project proposes a surface parking lot with approximately 55 regular parking
stalls and 4 parking stalls that comply with Americans with Disabilities Act (ADA) requirements.
Table XIII-3

Notes: dBA = A-weighted Decibels; Leq = Equivalent Sound Level
Source: Kariel, H. G., “Noise in Rural Recreational Environments,” Canadian Acoustics 19(5), 3-10, 1991.
It should be noted that parking lot noise generates instantaneous noise levels compared to noise
standards in the Ldn scale, which are averaged over time. As a result, actual noise levels over time
resulting from parking lot activities would be far lower. The adjoining residences to the east and south
would be located approximately 10 feet from the proposed surface parking lot. As such, parking lot
noise levels would be approximately 67 to 75 dBA at these sensitive receptors. However, parking lot
activities and associated noise levels are intermittent and sporadic, and an existing parking lot is located
within the same distance to the nearest adjoining residences as the proposed surface parking lot.
Therefore, as the Project would not introduce a new source of noise in the Project vicinity, and parking
lot noise would be infrequent, noise impacts would be less than significant.
Mitigation Measure
NOI-1 Prior to issuance of a Grading Permit, the Project applicant shall demonstrate, to the
satisfaction of the City of Arcadia Planning Division, that the Project complies with
the following:
x Construction contracts specify that all construction equipment, fixed or mobile,
shall be equipped with properly operating and maintained mufflers and other
State-required noise attenuation devices.
x The contractor shall provide evidence that a construction staff member will be
designated as a noise disturbance coordinator and will be present on-site during
construction activities. The noise disturbance coordinator shall be responsible for
responding to any local complaints about construction noise. When a complaint is
received, the noise disturbance coordinator shall notify the City within 24 hours
of the complaint and determine the cause of the noise complaint (e.g., starting too
early or bad muffler) and shall implement reasonable measures to resolve the
complaint, as deemed acceptable by the Planning & Community Development
Administrator (or designee). All notices that are sent to residential units
immediately surrounding the construction site and all signs posted at the
construction site shall include the contact name and the telephone number for the
noise disturbance coordinator. All necessary signage and notices shall be posted
on or sent to residential units immediately surrounding the construction site no
less than two weeks prior to the start of noise-generating construction activities on
the Project Site.
Artis Senior Housing Project
Draft Initial Study Page 75 April 2020
x During construction, stationary construction equipment shall be placed such that
emitted noise is directed away from sensitive noise receivers.
x Prior to issuance of any Grading or Building Permit, the Project applicant shall
demonstrate to the satisfaction of the Community Development Director (or
designee) that construction noise reduction methods shall be used where feasible.
These reduction methods may include shutting off idling equipment, installing
temporary acoustic barriers around stationary construction noise sources,
maximizing the distance between construction equipment staging areas and
occupied residential areas, and utilizing electric air compressors and similar power
tools.
x Construction haul routes shall be designed to avoid noise-sensitive uses (e.g.,
residences and convalescent homes) to the extent feasible.
b) Would the project result in generation of excessive groundborne vibration or
groundborne noise levels?
Less Than Significant Impact. Project construction can generate varying degrees of ground-borne
vibration, depending on the construction procedure and construction equipment used. Operation of
construction equipment generates vibrations that spread through the ground and diminish in
amplitude with distance from the source. The effect on buildings located in the vicinity of the
construction site often varies depending on soil type, ground strata, and construction characteristics
of the receiver building(s). The results from vibration can range from no perceptible effects at the
lowest vibration levels, to low rumbling sounds and perceptible vibration at moderate levels, to slight
damage at the highest levels. Groundborne vibrations from construction activities rarely reach levels
that damage structures.
Construction vibration impacts include human annoyance and building damage. Human annoyance
occurs when construction vibration rises significantly above the threshold of human perception for
extended periods of time. Building damage can be cosmetic or structural. Ordinary buildings that are
not particularly fragile would not experience any cosmetic damage (e.g., plaster cracks) at distances
beyond 30 feet. This distance can vary substantially depending on the soil composition and
underground geological layer between vibration source and receiver. In addition, not all buildings
respond similarly to vibration generated by construction equipment. For example, buildings that are
constructed with typical timber frames and masonry show that a vibration level of up to 0.2 inch-per-
second peak particle velocity (PPV) is considered safe and would not result in any construction
vibration damage.79 The City currently does not have a significance threshold to assess construction
vibration impacts.80 Therefore, this analysis uses the Federal Transit Administration (FTA)
architectural damage criterion for continuous vibrations at non-engineered timber and masonry
buildings of 0.2 inch-per-second PPV and human annoyance criterion of 0.2 inch-per-second PPV in
accordance with California Department of Transportation (Caltrans) guidance.81 The FTA has

generated from construction activities.

produced by construction equipment is illustrated in Table XIII-4.

Notes:
a Calculated using the following formula:
PPV equip = PPVref x (25/D)1.5
where: PPV (equip) = the peak particle velocity in in/sec of the equipment adjusted for the distance
PPV (ref) = the reference vibration level in in/sec from Table 7-4 of the FTA Transit Noise and Vibration Impact Assessment
Manual
D = the distance from the equipment to the receiver
Source: Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual, September 2018.
Ground-borne vibration decreases rapidly with distance. The nearest structures are located
approximately 28 feet to the south and 40 feet to the east of the proposed construction activities. As
indicated in Table XIII-4, vibration velocities from typical heavy construction equipment used during
Project construction would range from 0.003 (a small bulldozer) to 0.177 (vibratory roller) inch-per-
second PPV at the nearest structure (i.e., 28 feet) from the source of activity, which would not exceed
FTA’s 0.2 inch-per-second PPV threshold. Further, construction vibration would not cause excessive
human annoyance as the highest ground-borne vibration nearest sensitive receptors (i.e., 0.177 inch-
per-second PPV) would not exceed the 0.2 inch-per-second PPV human annoyance criteria.
Therefore, the proposed construction activities associated with the Project would not expose sensitive
receptors to excessive ground-borne vibration levels. As such, vibration impacts associated with
construction would be less than significant.
c) For a project located within the vicinity of a private airstrip or an airport land use plan or,
where such a plan has not been adopted, within two miles of a public airport or public use
airport, would the project expose people residing or working in the project area to
excessive noise levels?
No Impact. The nearest airport to the Project Site is the San Gabriel Airport (also known as El
Monte Airport), which is approximately 4.5 miles to the southeast. According to the County of Los
Angeles’ Airports and Airport Influence Areas Map , the Project Site is not located within the El Monte Airport
Influence Area.82 Additionally, the Project Site is not located within the vicinity of a private airstrip or
related facilities. Therefore, Project implementation would not expose people residing or working in
the Project area to excessive noise levels associated with aircraft, and no impacts would occur.

Discussion
a) Would the project induce substantial unplanned population growth in an area, either
directly (for example, by proposing new homes and businesses) or indirectly (for example,
through extension of roads or other infrastructure)?
Less Than Significant. The Proposed Project would construct an 80-bed senior-living, memory care
facility; however, it would not include construction of growth-inducing infrastructure, such as roadway
or utility extensions to areas not already provided with such services. The Project is anticipated to
generate approximately 80 residents and approximately 40 employees.83,84 Because the Project is
consistent with the underlying zoning and General Plan designation for the parcel, the population
growth associated with the Project would have been anticipated and planned for in the City of Arcadia
General Plan. Further, the SCAG 2016-2040 RTP/SCS provides population and employment growth
estimates for municipalities within its jurisdiction, including the City of Arcadia. The 2016-2040
RTP/SCS estimates that population in Arcadia will increase from 56,700 in 2012 to 65,900 by 2040,
and employment would increase from 28,900 in 2012 to 34,400 in 2040.85 Using these growth
forecasts, the Proposed Project would account for approximately 0.9 percent of forecasted population
growth between 2012 and 2040 and 0.7 percent of forecasted employment growth between 2012 and
2040 in the City of Arcadia. As such, the Proposed Project would not result in substantial unplanned
population growth in the area, either directly or indirectly and impacts would be less than significant.
b) Would the project displace substantial numbers of existing people or housing,
necessitating the construction of replacement housing elsewhere?
No Impact. The Project Site currently contains a restaurant building and surface parking lots and
does not currently contain any housing units. Thus, there are no current on-site residents or housing
83 Employees were calculated using the Southern California Association of Government’s Employment Density
Report, which provided an average employee density of 14.24 employees per acre for Special Care Facilities in Los
Angeles County. As the Project Site is 2.79 acres in size, the estimated number of employees serving the project
would be 40.

provision of new or physically altered governmental facilities, need for new or physically
altered governmental facilities, the construction of which could cause significant
environmental impacts, in order to maintain acceptable service ratios, response times or
other performance objectives for fire protection?
Less Than Significant Impact. The development of 80 assisted living and memory care residential
units, along with landscaping, outdoor living areas, drive aisles, and a surface parking lot, would
incrementally increase the demand for fire protection and emergency medical services.
In compliance with Standard Condition 4.13-1 in the City’s General Plan EIR, new development in
the City must comply with the California Fire Code and Arcadia Fire Department regulations
pertaining to building construction, fire flows and pressures, hydrant placement, and other
requirements that would reduce the creation of fire hazards and would facilitate emergency response.
Further, building plans and structures are reviewed by the Arcadia Fire Department for compliance
with applicable safety and emergency access standards. This review would determine if fire flow (1,000
gallons per minute for two hours for residential construction), access, and fire hydrant placement
would be sufficient or if expanded facilities are required. Upon review of the Project’s Site plan, the
Arcadia Fire Department determined that site circulation and emergency access would be sufficient
to accommodate a fire engine.
Artis Senior Housing Project
Draft Initial Study Page 79 April 2020
Therefore, with compliance with California Fire Code and Arcadia Fire Department regulations
governing hydrant placement, fire flows, and building construction, and with the Arcadia Fire
Department’s review and approval of the Project Site’s access and circulation plans, the Project would
have a less-than-significant impact on service ratios, response times, or other performance objectives
for fire protection and emergency medical services.
a.ii) Would the project result in substantial adverse physical impacts associated with the
provision of new or physically altered governmental facilities, need for new or physically
altered governmental facilities, the construction of which could cause significant
environmental impacts, in order to maintain acceptable service ratios, response times or
other performance objectives for police protection?
Less Than Significant Impact. The development of 80 assisted living and memory care residential
units, along with landscaping, outdoor living areas, drive aisles, and a surface parking lot, would
incrementally increase the demand for police protection (such as Project Site security and responding
to minor crimes). Law enforcement is provided by the Arcadia Police Department, with the nearest
police station located approximately 1.7 miles southeast of the Project Site, at 250 West Huntington
Drive. The Arcadia Police Department is equipped with an 18-bed, pre-arraignment jail, an evidence
lab, a computer forensics lab, and other investigative equipment.86 The Police Department is staffed
by 68 sworn officers and 33 non-sworn support staff for an officer to population ratio of 1.36 sworn
officers per 1,000 persons.87
As discussed in Section XIV, Population and Housing, above, the Proposed Project is anticipated to
generate approximately 80 residents and approximately 40 employees. The Proposed Project would
also include on-site security resources, such as security guards and orderlies, to patrol the grounds,
monitor locked entry and exit points to the property, and protect residents. Therefore, the Proposed
Project is anticipated to have limited need for police services, other than to address infrequent minor
crimes or vandalism issues on the property. Further, the Proposed Project would be required to
comply with Policy S-5.11 of the Arcadia General Plan, which states that new development projects
would be required “to pay their fair share of costs associated with any necessary increases in public
safety equipment, facilities, and staffing to provide life safety protection.”88
Therefore, because the Proposed Project would include security personnel to address Project-specific
security concerns, and because any other Project-related police service demands would be mitigated
by the required fair share fees paid by the Project applicant, impacts would be less than significant.
a.iii) Would the project result in substantial adverse physical impacts associated with the
provision of new or physically altered governmental facilities, need for new or physically
altered governmental facilities, the construction of which could cause significant
environmental impacts, in order to maintain acceptable service ratios, response times or
other performance objectives for schools?
No Impact. The Project Site is located within the Arcadia Unified School District; however, the
Project would include demolition of an existing restaurant building and construction of 80 memory
care residential units. Because the 80 units would be inhabited by seniors affected by memory loss,

there would be no school-age children living on the Project Site. The Project may indirectly result in
the increase of school-age children living in Arcadia through the addition of approximately 40
employees. A portion of these employees may choose to live in Arcadia; however, the City is
surrounded by urban areas that offer many housing options in other school districts. As such, the
number of school-age children associated with the Proposed Project that would live within the Arcadia
Unified School District would be negligible. Therefore, impact on schools would not occur.
a.iv) Would the project result in substantial adverse physical impacts associated with the
provision of new or physically altered governmental facilities, need for new or physically
altered governmental facilities, the construction of which could cause significant
environmental impacts, in order to maintain acceptable service ratios, response times or
other performance objectives for parks?
No Impact. As previously discussed, the Proposed Project would involve demolition of an existing
restaurant use and construction of an 80-unit memory care facility. The Project would include an
enclosed landscaped outdoor area with gardens, walking paths, and a gazebo on the south side of the
Project Site for use by the Project’s residents. As such, the Proposed Project would provide outdoor
recreation space for Project residents and would, therefore, not create a substantial adverse physical
impact on City park facilities. No impact to parks would occur.

provision of new or physically altered governmental facilities, need for new or physically

No Impact. The Project would involve the development of an 80-unit memory care facility, which
would provide on-site services, such as activities rooms and outdoor recreation space, for Project
residents. As such, Project residents are anticipated to have limited mobility and are not expected to
substantially increase the demand on public facilities, such as libraries and other government buildings.

would include construction of an outdoor, enclosed recreation space for Project residents that would
include walking paths, gardens, and a plaza. The environmental impacts associated with construction
of these outdoor amenities are included in the Project analysis discussed in this Initial Study.
Therefore, there would be no additional impacts associated with constructing these outdoor recreation
amenities beyond those already discussed.

Construction
Project construction is proposed to be completed in approximately 19 months. The phases of
construction include demolition, grading, paving, building construction, and architectural coating.
Demolition, grading, and paving are anticipated to take three months to complete; building
construction would be completed in 12 months; and architectural coating would be completed in four
months. The grading phase would occur over 10 days and would result in 1,485 cubic yards of cut and
3,350 cubic yards of fill. Therefore, 1,865 cubic yards of soil would be imported to the Project Site
during the grading phase. The City of Arcadia limits construction activities to between the hours of
7:00 a.m. and 6:00 p.m. on weekdays and between the hours of 8:00 a.m. and 5:00 p.m. on Saturday;
therefore, construction-related traffic would occur only during those time periods, on an intermittent
basis, depending on the scope and intensity of the work taking place.89 While construction traffic
would temporarily affect traffic flow on the surrounding street network, particularly along the truck
haul routes, the impacts would be temporary and would fluctuate in intensity throughout the
construction day and vary throughout the overall construction program, with less traffic generated in
phases following the demolition and grading phases. Because the construction traffic impacts
associated with the Proposed Project would be temporary, they would not significantly affect the
performance of the vehicular transportation network with respect to level of service standards or other
metrics related to congestion and travel delay.
Operation
Project-related, long-term traffic impacts include those of employee, visitor, and delivery vehicles
associated with the proposed memory care facility. A trip generation analysis, conducted for the
Proposed Project, compared anticipated trip generation associated with the Proposed Project to traffic
count data collected for the existing restaurant and bakery building.90 The analysis used the Institute
of Transportation Engineers (ITE) Trip Generation Manual, 10 th Edition (2017) to determine the trip
generation rates appropriate for an assisted living facility. The results of the Project trip generation
analysis are provided in Table XVII-1.

As shown in Table XVII-1, the Proposed Project is eligible for a trip credit since the existing
restaurant building is currently in operation. Therefore, while the Proposed Project would result in an
estimated 208 total daily vehicle trips, the number of new trips associated with the Project would be
less than zero because the existing restaurant use currently generates 374 more daily trips than would
be expected from the Proposed Project. Therefore, the Project would have a less-than-significant
impact regarding trip generation.
Regarding trip distribution, the existing Project Site has two access points, as shown in Figure A-7.
The West Colorado Boulevard driveway provides full access (right- and left-turn for both ingress and
egress) and the Michillinda Avenue driveway provides partial access (right-turn ingress and right-turn
egress only). The Proposed Project would have a single, full-access driveway along West Colorado
Boulevard, which would be shifted slightly east of the existing driveway. While the Project would
concentrate all Project-related ingress and egress to the West Colorado Boulevard driveway, the overall
estimated reduction in Project-related trips as compared with the existing restaurant use would result
in a negligible impact on intersection impacts at this driveway. Specifically, the anticipated change in
site trips entering and exiting the site at the West Colorado Boulevard driveway would range from
negative four to three during the a.m. and p.m. peak hours. As such, it is anticipated that these minimal
changes in site trips would not impact intersection operations at the proposed West Colorado
Boulevard driveway. Further, all traffic associated with the Project Site would be removed from the
existing Michillinda Avenue driveway. Therefore, the Proposed Project would have a less-than-
significant impact on trip distribution and intersection performance.
Finally, the Proposed senior living facility would include 80 units and would be dedicated to people
afflicted with Alzheimer’s disease or other memory disorders. The outdoor spaces on the south side
of the Proposed Project, which would be accessible to residents, would be contained/secured and
monitored by facility staff. As such, there would be little to no impact on surrounding bus, pedestrian,
or bicycle transit systems as a result of resident demand. Project employees would have a small impact
on bus, pedestrian, or bicycle systems; however, the difference between the number of employees and
visitors that would utilize transit or bicycle infrastructure to access the Project as compared with the
number of employees and patrons using transit or bicycle infrastructure to access the existing
restaurant is anticipated to be negligible. Further, the Proposed Project would not alter the existing
Artis Senior Housing Project
Draft Initial Study Page 84 April 2020
bus stop in the West Colorado Boulevard right-of-way on the north side of the Project Site. As such,
there would be no impact on transit, bicycle, or pedestrian facilities as a result of the Proposed Project.
In summary, the Project would not conflict with a program, plan, ordinance, or policy addressing the
circulation system, taking into account all modes of transportation including transit, roadways, bicycle
and pedestrian facilities, and, as such, impacts related to transportation would be less than significant.
b) Would the project conflict with CEQA Guidelines Section 15064.3, subdivision (b)?
Less Than Significant Impact. By July 1, 2020, transportation impact assessments prepared in
accordance with CEQA will be required to determine if a Proposed Project would conflict with CEQA
Guidelines Section 15064.3(b), which outlines a new set of criteria for analyzing transportation impacts
using vehicle miles traveled (VMT) as the primary measure of transportation impact. VMT is generally
defined as the amount and the distance of automobile travel associated with a Project. The City has
not adopted guidelines to set new significance criteria for transportation impacts based on VMT for
land use projects and plans in accordance with this checklist question. However, since the Project will
be considered for approval prior to July 1, 2020, the Project is not required to demonstrate compliance
with CEQA Guidelines Section 15064.3(b).
Nevertheless, as discussed in Checklist Question XVII.a, above, the Project would replace an existing
Coco’s restaurant with an 80-bed assisted living facility. As shown above, when compared to existing
conditions, the Project would result in a substantial reduction in daily trips. Given the overall
substantial reduction in trips based on the trip generation analysis, the Project's impact on Citywide
and regional VMT would be considered less than significant.
c) Would the project substantially increase hazards due to a geometric design feature (e.g.,
sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)?
Less Than Significant Impact. The Proposed Project is located on a 2.79-acre property at the corner
of a major intersection. The Project proposes a surface parking lot with drive aisle and a drop-off
circle in front of the main entrance (northern building elevation). The Project would not generate
incompatible uses of area roadways, such as large farm equipment, that could impair circulation or
safety on area roads. Further, there is no internal street network proposed as part of the Project and,
therefore, no potential hazards associated with a geometric design feature, such as a sharp curve, would
occur within the Project Site. The Project would result in a single entrance and exit driveway onto
West Colorado Boulevard, as described above; however, this driveway would be designed to meet the
mandatory design standards of the City of Arcadia as it relates to width, intersection control, and sight
distance. Therefore, adherence to applicable City requirements would ensure the Proposed Project
would not result in any hazardous geometric design feature, and impacts would be less than significant.
d) Would the project result in inadequate emergency access?
Less Than Significant Impact. Project-related building plans and structures would be reviewed by
the Arcadia Fire Department for compliance with applicable safety and emergency access standards.
This review would determine if fire flow, access, and fire hydrant placement are sufficient or if
expanded facilities are required. Further, the Project Site is located in an urban setting, surrounded by
multiple arterial roadways that could lead to the Proposed Project’s driveway on West Colorado
Boulevard. As such, because the Project Site would be designed to accommodate emergency response
vehicles and because it is located in an urban environment where the surrounding street network
Artis Senior Housing Project
Draft Initial Study Page 85 April 2020
allows for access to the Project Site from multiple directions, impacts related to emergency access
would be less than significant.

No Impact. The Project Site is currently developed with a restaurant building constructed in 1976
along with a paved surface parking and vehicle driveways. As discussed in Section V, Cultural
Resources, the current restaurant building does not meet the age requirement for evaluation for
eligibility for listing in the California Register or in a local register. Further, a records search at the
South Central Coastal Information Center (SCCIC) determined that there are no documented historic
or prehistoric cultural resources on or within a quarter-mile radius of the Project Site. Therefore, the
Project would not cause an adverse change in the significance of a tribal cultural resource, defined in
PRC Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in

Less Than Significant Impact. Approved by Governor Brown on September 25, 2014, AB 52
established a formal consultation process for California Native American tribes to identify potential
significant impacts to tribal cultural resources as defined in PRC Section 21074, as part of CEQA. As
specified in AB 52, lead agencies must provide notice to tribes that are traditionally and culturally
affiliated with the geographic area of a project site if the tribe has submitted a written request to be
notified. The tribe must respond to the lead agency within 30 days of receipt of the notification if it
wishes to engage in consultation on the project, and the lead agency must begin consultation within
30 days of receiving the request for consultation.
In compliance with AB 52, on January 10, 2020, the City of Arcadia sent a notice to the Gabrieleño
Band of Mission Indians–Kizh Nation (Gabrieleño) and the Gabrielino-Tongva Tribe. On January
23, 2020, Andrew Salas, of the Gabrieleño submitted a formal request to consult with the City. The
City did not receive a consultation request from the Gabrielino-Tongva Tribe within the 30 day
consultation request period.
The tribal consultation process commenced on April 1, 2020 via a conference call attended by Andrew
Salas and Matt Teutimez of the Gabrieleño, Lisa Flores and Vanessa Quiroz of the City of Arcadia,
and John Bellas and Madonna Marcelo of Michael Baker International (the City’s environmental
consultant). During the phone consultation, City staff discussed the receipt of the Gabrieleño’s request
for consultation, described the scope of the Project, and provided general information, including
proposed excavation activities. In response, the Gabrieleño provided their knowledge of Arcadia and
the Project area, including Rancho Santa Anita (within the boundaries of which the Project Site is
located), the former Gabrieleño Native American village, the sacred village of Sheshiikwanonga/
Sisitcanongna, and trade routes in the vicinity of the Project Area, indicating that these trade routes
were considered cultural landscapes that are protected under AB 52 as a tribal cultural resources.
On April 2, 2020, City staff requested, via e-mail, the documents that were referenced by the
Gabrieleño representatives during the phone consultation. On April 2, 2020, the Gabrieleño provided
the articles, maps, and explanatory text that were verbally explained during the phone consultation.
Review of the maps and articles provided by the Gabrieleño included information about trade routes
and identified structures within the greater Arcadia area; however, these resources did not demonstrate
that there is an existing tribal cultural resource within the Project Site. As such, no evidence has been
submitted which identifies the specific location of the Project Site as sensitive or containing tribal
cultural resources, and no criteria have been provided to indicate why the Project area should be
Artis Senior Housing Project
Draft Initial Study Page 87 April 2020
considered sensitive enough such that monitoring for tribal cultural resources would be required to
avoid adverse impacts. CEQA only requires mitigation measures if substantial evidence exists of
potentially significant impacts. CEQA Guidelines Section 15126.4(a)(4)(A) states “there must be an
essential nexus (i.e., connection) between the mitigation measure and a legitimate government
interest.” Therefore, based upon the record, the City has determined that no substantial evidence
exists to support a conclusion that the Proposed Project may cause a significant impact on tribal
cultural resources. As such, the City has no basis under CEQA to impose any related mitigation
measures.
Nevertheless, while no tribal cultural resources are anticipated to be affected by the Project, the City
will voluntarily impose mitigation measures as an additional protection to address the inadvertent
discovery of tribal cultural resources. These voluntarily-imposed mitigation measures, Mitigation
Measure TCR-1 through Mitigation Measure TCR-4, are described in further detail below.
TCR-1 Retail a Native American Monitor/Consultant. The Project Applicant shall be
required to retain and compensate for the services of a tribal monitor/consultant, who
is both approved by the Gabrieleño Band of Mission Indians-Kizh Nation Tribal
Government and listed under the Native American Heritage Commission’s (NAHC)
Tribal Contact list for the area of the project location. This list is provided by the
NAHC. The monitor/consultant shall only be present on-site during the construction
phases that involve ground disturbing activities. Ground disturbing activities are
defined by the Gabrieleño Band of Mission Indians-Kizh Nation as activities that may
include, but are not limited to, pavement removal, pot-holing or auguring, grubbing,
tree removals, boring, grading, excavation, drilling, and trenching, within the Project
area. The tribal Monitor/consultant shall complete daily monitoring logs that will
provide descriptions of the day’s activities, including construction activities, locations,
soil, and any cultural materials identified. The on-site monitoring shall end when the
Project Site grading and excavation activities are completed or when the tribal
representatives and monitor/consultant have indicated that the site has a low potential
for impacting tribal cultural resources.
TCR-2 Unanticipated Discovery of Tribal Cultural and Archaeological Resources.
Upon discovery of any tribal cultural or archaeological resources, construction
activities shall cease in the immediate vicinity of the find until the find can be assessed.
All tribal cultural and archaeological resources unearthed by Project construction
activities shall be evaluated by the qualified archaeologist and tribal
monitor/consultant approved by the Gabrieleño Band of Mission Indians-Kizh
Nation. If the resources are Native American in origin, the Gabrieleño Band of
Mission Indians-Kizh Nation shall coordinate with the landowner regarding treatment
and curation of these resources. Typically, the tribe will request preservation in place
or recovery for educational purposes. Work may continue on other parts of the Project
Site while evaluation and, if necessary, additional protective mitigation takes place
(CEQA Guidelines Section15064.5 [f]). If a resource is determined by the qualified
archaeologist to constitute a “historical resource” or “unique archaeological resource,”
time allotment and funding sufficient to allow for implementation of avoidance
measures, or appropriate mitigation, must be available. The treatment plan established
for the resources shall be in accordance with CEQA Guidelines Section 15064.5(f) for
historical resources. For unique archaeological resources, preservation in place is the
preferred manner of treatment in accordance with PRC Section 21083.2(b). If
Artis Senior Housing Project
Draft Initial Study Page 88 April 2020
preservation in place is not feasible, treatment may include implementation of
archaeological data recovery excavations to remove the resource along with
subsequent laboratory processing and analysis. All tribal cultural resources shall be
returned to the tribe. Any historic archaeological material that is not Native American
in origin shall be curated at a public, nonprofit institution with a research interest in
the materials, such as the Natural History Museum of Los Angeles County or the
Fowler Museum, if such an institution agrees to accept the material. If no institution
accepts the archaeological material, they shall be offered to the tribe or a local school
or historical society in the area for educational purposes.
TCR-3 Unanticipated Discovery of Human Remains and Associated Funerary
Objects. Native American human remains are defined in PRC 5097.98 (d)(1) as an
inhumation or cremation, and in any state of decomposition or skeletal completeness.
Funerary objects, called associated grave goods in PRC 5097.98, are also to be treated
according to this statute. Health and Safety Code 7050.5 dictates that any discoveries
of human skeletal material shall be immediately reported to the County Coroner and
excavation halted until the coroner has determined the nature of the remains. If the
coroner recognizes the human remains to be those of a Native American or has reason
to believe that they are those of a Native American, he or she shall contact, by
telephone within 24 hours, the NAHC and PRC 5097.98 shall be followed.
Upon discovery of human remains, the tribal and/or archaeological monitor/
consultant/consultant shall immediately divert work at minimum of 150 feet and place
an exclusion zone around the discovery location. The monitor/consultant(s) shall then
notify the tribe, the qualified lead archaeologist, and the construction manager who
will call the coroner. Work shall continue to be diverted while the coroner determines
whether the remains are human and subsequently Native American. The discovery is
to be kept confidential and secure to prevent any further disturbance. If the finds are
determined to be Native American, the coroner shall notify the NAHC as mandated
by State law, who will then appoint a Most Likely Descendent (MLD). If the
Gabrieleño Band of Mission Indians – Kizh Nation is designated MLD, the Koo-nas-
gna Burial Policy shall be implemented. To the tribe, the term “human remains”
encompasses more than human bones. In ancient, as well as, historic times, tribal
traditions included, but were not limited to, the preparation of the soil for burial, the
burial of funerary objects with the deceased, and the ceremonial burning of human
remains. The prepared soil and cremation soils are to be treated in the same manner
as bone fragments that remain intact. Associated funerary objects are objects that, as
part of the death rite or ceremony of a culture, are reasonably believed to have been
placed with individual human remains either at the time of death or later; other items
made exclusively for burial purposes or to contain human remains can also be
considered as associated funerary objects.
Prior to the continuation of ground disturbing activities, the land owner shall arrange
a designated site location within the footprint of the Project for the respectful reburial
of the human remains and/or ceremonial objects. In the case where discovered human
remains cannot be fully documented and recovered on the same day, the remains shall
be covered with muslin cloth and a steel plate that can be moved by heavy equipment
placed over the excavation opening to protect the remains. If this type of steel plate is
not available, a 24-hour guard should be posted outside of working hours. The tribe
Artis Senior Housing Project
Draft Initial Study Page 89 April 2020
shall make every effort to recommend diverting the Project and keeping the remains
in situ and protected. If the Project cannot be diverted, it may be determined that
burials shall be removed. The tribe shall work closely with the qualified archaeologist
to ensure that the excavation is treated carefully, ethically and respectfully. If data
recovery are approved by the tribe, documentation shall be taken which includes at a
minimum detailed descriptive notes and sketches. Additional types of documentation
shall be approved by the tribe for data recovery purposes. Cremations shall either be
removed in bulk or by means as necessary to ensure completely recovery of all material.
If the discovery of human remains includes four or more burials, the location is
considered a cemetery and a separate treatment plan shall be created. Once complete,
a final report of all activities is to be submitted to the tribe and the NAHC. The tribe
does not authorize any scientific study or the utilization of any invasive and/or
destructive diagnostics on human remains. Each occurrence of human remains and
associated funerary objects shall be stored using opaque cloth bags. All human
remains, funerary objects, sacred objects and objects of cultural patrimony shall be
removed to a secure container on site if possible. These items shall be retained and
reburied within six months of recovery. The site of reburial/repatriation shall be on
the Project Site but at a location agreed upon between the tribe and the landowner at
a site to be protected in perpetuity. There shall be no publicity regarding any cultural
materials recovered.
TCR-4 Professional Standards. Archaeological and Native American monitoring and
excavation during construction projects shall be consistent with current professional
standards. All feasible care to avoid any unnecessary disturbance, physical
modification, or separation of human remains and associated funerary objects shall be
taken. Principal personnel must meet the Secretary of Interior’s Standards for
archaeology and have a minimum of 10 years of experience as a principal investigator
working with Native American archaeological sites in Southern California. The
qualified archaeologist shall ensure that all other personnel are appropriately trained
and qualified.

Water
The City of Arcadia provides water service to a majority of the City and currently derives its water
supply from groundwater wells that produce water from two groundwater basins, the Main San
Gabriel Basin and the Raymond Basin, with the Main San Gabriel Basin as the City’s primary
groundwater source.91 According to the City’s 2015 Urban Water Management Plan (UWMP), the
City has not experienced water supply deficiencies as a result of current management practices in the
Main San Gabriel Basin and the Raymond Basin. As determined in the 2015 UWMP, the minimum
water supplies available at the end of an average water year, single dry year, and multiple dry years
would be at least equal to, if not greater than, the City’s water demand. In addition, as concluded in
the 2015 UWMP, based on current management practices and reduced pumping in the Raymond
Basin, the City will be able to rely on the Main San Gabriel Basin, the Raymond Basin, and imported
water for adequate supply through year 2035 under single year and multiple year droughts.
As shown in Table XIX-1, the Proposed Project does not meet the criteria to prepare a project-
specific Water Supply Assessment under Senate Bill (SB) 610.92 In addition, as presented in Table
XIX-1, the Proposed Project would result in a net reduction in water consumption due to the change
in land use from a high turnover restaurant to an assisted living facility. Accordingly, the Project would

not require or result in the relocation or construction of new or expanded water treatment facility, the
construction or relocation of which could cause significant environmental effects. Therefore, impacts
related to water consumption and water supply would be less than significant.

a Based on a review of other projects and water supply assessment reports prepared for projects in the Los
Angeles Metropolitan area, the amount of wastewater generated by a project has been estimated to be
approximately the same as the amount of water consumed by such project. It is noted that some amount is lost
due to evapotranspiration and landscaping irrigation; however, these quantities are minimal compared to the
consumption and generation by the actual uses.
b Rates from the Sanitation Districts of County of Los Angeles.
c Rate for convalescent homes was utilized.
Wastewater
Wastewater generated by the City is treated by the Sanitation Districts of Los Angeles County
(Sanitation Districts). Wastewater is collected within the City’s local sewer collection system, which tie
into one of the Sanitation Districts’ regional truck sewer lines traversing the City.93 The regional truck
sewer lines deliver wastewater to one or more water reclamation plants owned by the Sanitation
Districts for treatment, including the Whittier Narrows Water Reclamation Plant (WNWRP) and the
Joint Water Pollution Control Plant (JWPCP).
As presented above in Table XIX-1, the Proposed Project would result in a net reduction in
wastewater generation due to the change in land use from a high turnover restaurant to an assisted
living facility. Accordingly, the Project would not require or result in the relocation or construction of
new or expanded wastewater treatment facility, the construction or relocation of which could cause
significant environmental effects. Therefore, impacts related to wastewater generation, specifically to
the WNWRP and the JWPCP, would be less than significant.
Storm Drains
The Project Site currently drains to an existing private storm drain located at the southeastern corner
of the Project Site. As discussed above in Section X, Hydrology and Water Quality, of this Initial
Study, the Project would slightly reduce the amount of impervious surfaces on the Project Site due to
the increase in the amount of pervious landscape areas proposed by the Project as compared to
existing conditions. Further, the Project’s LID Plan would be reviewed and approved by the City
during the plan-check process, ensuring that the Project’s drainage plan would conform to local and
regional regulations governing Project Site discharge to storm drains. Specifically, the LID Plan would
result in stormwater runoff retention on-site for the runoff from the 85 th percentile 24-hour runoff

Artis Senior Housing Project
Draft Initial Study Page 92 April 2020
event. Only stormwater overflow from the Project Site would drain to the existing private storm drain
at the southeastern corner of the Project Site. Therefore, the Project would not contribute to additional
runoff as compared to existing conditions. Accordingly, the Project would not require or result in the
relocation or construction of new or expanded storm drain facilities, the construction or relocation of
which could cause significant environmental effects. Therefore, impacts related to storm drains would
be less than significant.
Electricity and Natural Gas
Southern California Edison (SCE) and Southern California Gas Company (SoCalGas) provide
electricity and natural gas services to the Project Site, respectively. As presented in Table VI-1 in
Section VI, Energy, of this Initial Study, the Proposed Project would result in a net reduction in
electricity and natural gas consumption due to the change in land use from a high turnover restaurant
to an assisted living facility. Accordingly, the Project would not require or result in the relocation or
construction of new or expanded power or natural gas lines, the construction or relocation of which
could cause significant environmental effects. Therefore, impacts related to electricity and natural gas
would be less than significant.
Telecommunications
Telecommunication services are provided by private companies, the selection of which is at the
discretion of the Applicant. Upgrades to existing telecommunication facilities and construction of new
facilities to meet the demand of users are determined by telecommunication providers and is subject
to its own environmental review. Accordingly, Project impacts to telecommunication facilities would
be less than significant.
b) Would the project have sufficient water supplies available to serve the project and
reasonably foreseeable future development during normal, dry and multiple dry years?
Less Than Significant Impact. As discussed above, the 2015 UWMP concluded that the City will
be able to rely on the Main San Gabriel Basin, the Raymond Basin, and imported water for adequate
supply through year 2035 under single year and multiple year droughts. In addition, as shown in Table
XIX-1, the Proposed Project would result in a net reduction in water consumption due to the change
in land use from a high turnover restaurant to an assisted living facility. Accordingly, there would be
sufficient water supplies available to serve the Project and reasonably foreseeable future development
during normal, dry and multiple dry years. Therefore, impacts to water supplies would be less than
significant.
c) Would the project result in a determination by the wastewater treatment provider which
serves or may serve the project that it has inadequate capacity to serve the project’s
projected demand in addition to the provider’s existing commitments?
Less Than Significant Impact. As presented above, the Proposed Project would result in a net
reduction in wastewater generation due to the change in land use from a high turnover restaurant to
an assisted living facility. Accordingly, the Project would not affect the capacity of the WNWRP or
the JWPCP for treatment of wastewater. Therefore, impacts related to wastewater treatment would
be less than significant.

d) Would the project generate solid waste in excess of State or local standards, or in excess
of the capacity of local infrastructure, or otherwise impair the attainment of solid waste
reduction goals?
e) Would the project comply with federal, state, and local management and reduction
statutes and regulations related to solid waste?
Less Than Significant Impact. The Project Site is currently served by a commercial hauler, which
collects and transports waste generated by the existing restaurant to multiple local landfills. The City’s
General Plan Update Program Environmental Impact Report determined that there would be no
significant adverse impact on landfill capacity and that continuation of existing City and County
programs and implementation of pertinent goals, policies, and implementation actions in the General
Plan Update would provide for future developments’ compliance with solid waste regulations.94 In
addition, the Project would be required to comply with federal, State, and local management and
reduction statutes and regulations related to solid waste to ensure that the solid waste stream diverted
to landfills and recycling facilities is reduced in accordance with existing regulations. Furthermore, as
shown in Table XIX-2, the Proposed Project would result in a net reduction in solid waste generation
due to the change in land use from a high turnover restaurant to an assisted living facility. Accordingly,
the Project would not generate solid waste in excess of State or local standards, or in excess of the
capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals.
Therefore, impacts related to solid waste generation would be less than significant.

Discussion
a) If located in or near state responsibility areas or lands classified as very high fire hazard
severity zones, would the project substantially impair an adopted emergency response
plan or emergency evacuation plan?
No Impact. As stated in Section IX.g, above, the Project Site is not located within or adjacent to a
Very High Fire Hazard Severity Zone (VHFHSZ), as designated by the California Department of
Forestry and Fire Protection.95 VHFHSZs in the City of Arcadia are concentrated on the northeastern
side of the City, in the foothills near the Cities of Monrovia and Sierra Madre, approximately 2.1 miles
northeast of the Project Site. The Project Site is in a fully urbanized area with an urban street network,
a fully pressurized water system, and managed landscaping limited to decorative trees and shrubs. As
such, wildland fires would not occur on or near the Project Site. Regardless, in any disaster warranting
evacuation, the exact emergency routes used would depend on a number of variables, including the
type, scope, and location of the incident. It is the responsibility of emergency service and/or
appropriate public officials to adequately assess the situation so that safe and efficient evacuation
routes are selected. As the Project Site is in a fully urbanized area with multiple major arterial streets
and a major highway within close proximity, the Proposed Project would not substantially impair an
adopted emergency response plan or emergency evacuation plan, and no impact would occur.

severity zones, would the project expose people or structures to significant risks, including
downslope or downstream flooding or landslides, as a result of runoff, post-fire slope
instability, or drainage changes?
No Impact. The Project Site is not within or near a VHFHSZ. The Project Site is within a flat,
urbanized area that is adjacent to existing commercial and residential structures. Therefore, the Project
would not expose people or structures to significant risks, including downslope or downstream
flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes. As such,
no impact would occur.

Discussion
a) Does the project have the potential to substantially degrade the quality of the
environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or
wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or
animal community, substantially reduce the number or restrict the range of a rare or
endangered plant or animal or eliminate important examples of the major periods of
California history or prehistory?
Less Than Significant Impact With Mitigation Incorporated. Based on the analysis in Section
IV, Biological Resources, of this Initial Study, the Proposed Project would not have substantial
impacts to special-status species, stream habitat, and wildlife dispersal. A mitigation measure is
proposed (i.e., Mitigation Measure BIO-1) to ensure that tree removal would not pose a significant
impact on migratory wildlife species. Furthermore, the Proposed Project would not affect the local,
regional, or national populations or ranges of any plant or animal species and would not threaten any
plant communities. Similarly, as discussed in Section V, Cultural Resources, and Section VII, Geology
and Soils, of this Initial Study, with the incorporation of Mitigation Measures CUL-1 and GEO-1,
the Proposed Project would not have substantial impacts to historical, archaeological, or
paleontological resources and, thus, would not eliminate any important examples of California history
or prehistory. Therefore, the Proposed Project would not result in a Mandatory Finding of
Significance due to impacts to biological, cultural, or paleontological resources.
b) Does the project have impacts that are individually limited, but cumulatively
considerable? ("Cumulatively considerable" means that the incremental effects of a
project are considerable when viewed in connection with the effects of past projects, the
effects of other current projects, and the effects of probable future projects)?
Less Than Significant Impact. A significant cumulative impact may occur if the Project, in
conjunction with related projects in the region, would result in impacts that are less than significant
when viewed separately but would be significant when viewed together. When considering the
Proposed Project in combination with other past, present, and reasonably foreseeable future projects
in the vicinity of the Project Site, the Proposed Project does not have the potential to cause impacts
that are cumulatively considerable. As detailed in the above discussions, the Proposed Project would
not result in any significant and unmitigable impacts in any environmental categories. In all cases, the
impacts associated with the Project are limited to the Project Site and are of such a negligible degree
that they would not result in a significant contribution to any cumulative impacts. In some cases, the
Artis Senior Housing Project
Draft Initial Study Page 97 April 2020
Project would result in a net reduction when compared to existing conditions (i.e., related to emissions,
water consumption, and wastewater and solid waste generation). Therefore, the Proposed Project
would not result in a Mandatory Finding of Significance due to cumulative impacts.
c) Does the project have environmental effects which will cause substantial adverse effects
on human beings, either directly or indirectly?
Less Than Significant Impact With Mitigation Incorporated . As detailed above, the Proposed
Project does not have the potential to result in direct or indirect substantial adverse effects on human
beings. Although construction noise is allowed during the City’s allowable construction hours and is
not considered to be a significant impact during those hours, the Project could expose adjoining
residential uses to temporary high noise levels (91 to 104 dBA) during construction activities.
However, Mitigation Measure NOI-1 is recommended to reduce short-term construction noise
impacts through noise reduction methods to a less-than-significant level. In all other environmental
issue areas, the Proposed Project does not approach or exceed any significance thresholds typically
associated with direct or indirect effects on people, such as air, water, or land pollution, natural
environmental hazards, transportation-related hazards, or adverse effects to emergency service
response. Therefore, the Proposed Project would not result in a Mandatory Finding of Significance
due to direct or indirect effects on human beings.

SECTION E. LIST OF MITIGATION MEASURES
Biological Resources
BIO-1 Tree removal shall not occur during the local nesting season (February 1 to
September 15 for nesting birds and February 1 to June 30 for nesting raptors), to the
extent practicable. If any construction or tree removal occurs during the nesting
season, a nesting bird survey shall be conducted by a qualified biologist prior to
commencement of grading or removal of any trees on the property. If the biologist
determines that nesting birds are present, restrictions may be placed on construction
activities in the vicinity of the nest observed until the nest is no longer active, as
determined by the biologist based on the location of the nest, type of the construction
activities, the existing human activity in the vicinity of the nest, and the sensitivity of
the nesting species. Grading and/or construction may resume in this area when a
qualified biologist has determined that the nest is no longer occupied, and all juveniles
have fledged. This measure shall be implemented to the satisfaction of the City of the
Planning & Community Development Administrator or Designee.
BIO-2 Prior to issuance of a building permit, the applicant shall demonstrate that the Project
landscaping plan and planned construction are consistent with the City’s Tree
Protection Ordinance and the Protected Tree Study. The tree protection activities shall
include the following:
1. Prior to demolition, the contractor and consulting arborist shall meet on-site to
make sure tree protection zones are established around all protected trees to be
preserved and to review the goals for the tree protection plan.
2. Tree protection zone fences shall be placed around each protected tree. Fences
shall be at least 4 feet tall and constructed of chain-link fencing secured on metal
posts. Where fences are not feasible (e.g., in haul routes or areas where workers
will need frequent access), soil and root protection material can be installed.
3. The contractor shall maintain the fences and/or soil protection material
throughout the completion of the Project. No staging of materials or equipment
or washing out shall occur within the fenced protected zones.
4. Trees should be irrigated throughout the year. A deep watering that provides
good soil moisture to a depth of 16 inches is optimal. The trees shall be deeply
water once every 21 to 28 days during the summer and fall seasons when rain is
unlikely.
5. For Tree No. 49, a protected deodar cedar located on the Project Site’s Colorado
Boulevard frontage, the deadwood shall be removed to prevent the dead
branches from falling. However, no reduction pruning in the live crown of the
tree is required. The tree shall be monitored for its health during the life of the
Project, and irrigation shall occur at the same frequency of the other trees.
6. The arborist shall monitor a few critical phases of the Project, including pre-
demolition, to direct the installation of protective fences and soil protection
measures; grading and excavation; any utility or drainage trenching that is
required within a tree protection zone; and a final evaluation during the landscape
installation phase.
Artis Senior Housing Project
Draft Initial Study Page 99 April 2020
7. Additional construction best practices described in the Protected Tree Report
shall be implemented.
Cultural Resources
CUL-1 Treatment of previously unidentified archaeological deposits: If suspected prehistoric
or historical archaeological deposits are discovered during construction, all work
within 25 feet of the discovery shall be redirected and a Secretary of the Interior
Professional Qualified archaeologist and/or Registered Professional Archaeologist
shall assess the situation and make recommendations regarding the treatment of the
discovery. Impacts to significant archaeological deposits shall be avoided if feasible,
but if such impacts cannot be avoided, the deposits shall be evaluated for their
eligibility for the California Register of Historical Resources. If the deposits are not
eligible, no further protection of the find is necessary. If the deposits are eligible,
impacts shall be avoided or mitigated. Acceptable mitigation may consist of, but is not
necessarily limited to, systematic recovery and analysis of archaeological deposits,
recording the resource, preparation of a report of findings, and accessioning recovered
archaeological materials at an appropriate curation facility.
Geology and Soils
GEO-1 Paleontological Resource Monitor: If paleontological resources (fossils) are discovered
during Project grading, work shall be halted in that area until a qualified paleontologist
can be retained to assess the significance of the find. The Project paleontologist shall
monitor remaining earth-moving activities at the Project Site and shall be equipped to
record and salvage fossil resources that may be unearthed during grading activities.
The paleontologist shall be empowered to temporarily halt or divert grading
equipment to allow recording and removal of the unearthed resources. Any fossils
found shall be evaluated in accordance with the CEQA Guidelines and offered for
curation at an accredited facility approved by the City of Arcadia. Once grading
activities have ceased or the paleontologist determines that monitoring is no longer
necessary, monitoring activities shall be discontinued.
Noise
NOI-1 Prior to issuance of a Grading Permit, the Project applicant shall demonstrate, to the
satisfaction of the City of Arcadia Planning Division, that the Project complies with
the following:
1. Construction contracts specify that all construction equipment, fixed or mobile,
shall be equipped with properly operating and maintained mufflers and other
State-required noise attenuation devices.
2. The contractor shall provide evidence that a construction staff member will be
designated as a noise disturbance coordinator and will be present on-site during
construction activities. The noise disturbance coordinator shall be responsible
for responding to any local complaints about construction noise. When a
complaint is received, the noise disturbance coordinator shall notify the City
within 24 hours of the complaint and determine the cause of the noise
complaint (e.g., starting too early or bad muffler) and shall implement
reasonable measures to resolve the complaint, as deemed acceptable by the
Artis Senior Housing Project
Draft Initial Study Page 100 April 2020
Planning & Community Development Administrator (or designee). All notices
that are sent to residential units immediately surrounding the construction site
and all signs posted at the construction site shall include the contact name and
the telephone number for the noise disturbance coordinator. All necessary
signage and notices shall be posted on or sent to residential units immediately
surrounding the construction site no less than two weeks prior to the start of
noise-generating construction activities on the Project Site.
3. During construction, stationary construction equipment shall be placed such
that emitted noise is directed away from sensitive noise receivers.
4. Prior to issuance of any Grading or Building Permit, the Project applicant shall
demonstrate to the satisfaction of the Community Development Director (or
designee) that construction noise reduction methods shall be used where
feasible. These reduction methods may include shutting off idling equipment,
installing temporary acoustic barriers around stationary construction noise
sources, maximizing the distance between construction equipment staging
areas and occupied residential areas, and utilizing electric air compressors and
similar power tools.
5. Construction haul routes shall be designed to avoid noise-sensitive uses (e.g.,
residences and convalescent homes) to the extent feasible.
Tribal Cultural Resources
TCR-1 Retail a Native American Monitor/Consultant. The Project Applicant shall be
required to retain and compensate for the services of a tribal monitor/consultant, who
is both approved by the Gabrieleño Band of Mission Indians-Kizh Nation Tribal
Government and listed under the Native American Heritage Commission’s (NAHC)
Tribal Contact list for the area of the project location. This list is provided by the
NAHC. The monitor/consultant shall only be present on-site during the construction
phases that involve ground disturbing activities. Ground disturbing activities are
defined by the Gabrieleño Band of Mission Indians-Kizh Nation as activities that may
include, but are not limited to, pavement removal, pot-holing or auguring, grubbing,
tree removals, boring, grading, excavation, drilling, and trenching, within the Project
area. The tribal Monitor/consultant shall complete daily monitoring logs that will
provide descriptions of the day’s activities, including construction activities, locations,
soil, and any cultural materials identified. The on-site monitoring shall end when the
Project Site grading and excavation activities are completed or when the tribal
representatives and monitor/consultant have indicated that the site has a low potential
for impacting tribal cultural resources.
TCR-2 Unanticipated Discovery of Tribal Cultural and Archaeological Resources.
Upon discovery of any tribal cultural or archaeological resources, construction
activities shall cease in the immediate vicinity of the find until the find can be assessed.
All tribal cultural and archaeological resources unearthed by Project construction
activities shall be evaluated by the qualified archaeologist and tribal
monitor/consultant approved by the Gabrieleño Band of Mission Indians-Kizh
Nation. If the resources are Native American in origin, the Gabrieleño Band of
Mission Indians-Kizh Nation shall coordinate with the landowner regarding treatment
and curation of these resources. Typically, the tribe will request preservation in place
Artis Senior Housing Project
Draft Initial Study Page 101 April 2020
or recovery for educational purposes. Work may continue on other parts of the Project
Site while evaluation and, if necessary, additional protective mitigation takes place
(CEQA Guidelines Section15064.5 [f]). If a resource is determined by the qualified
archaeologist to constitute a “historical resource” or “unique archaeological resource,”
time allotment and funding sufficient to allow for implementation of avoidance
measures, or appropriate mitigation, must be available. The treatment plan established
for the resources shall be in accordance with CEQA Guidelines Section 15064.5(f) for
historical resources. For unique archaeological resources, preservation in place is the
preferred manner of treatment in accordance with PRC Section 21083.2(b). If
preservation in place is not feasible, treatment may include implementation of
archaeological data recovery excavations to remove the resource along with
subsequent laboratory processing and analysis. All tribal cultural resources shall be
returned to the tribe. Any historic archaeological material that is not Native American
in origin shall be curated at a public, nonprofit institution with a research interest in
the materials, such as the Natural History Museum of Los Angeles County or the
Fowler Museum, if such an institution agrees to accept the material. If no institution
accepts the archaeological material, they shall be offered to the tribe or a local school
or historical society in the area for educational purposes.
TCR-3 Unanticipated Discovery of Human Remains and Associated Funerary
Objects. Native American human remains are defined in PRC 5097.98 (d)(1) as an
inhumation or cremation, and in any state of decomposition or skeletal completeness.
Funerary objects, called associated grave goods in PRC 5097.98, are also to be treated
according to this statute. Health and Safety Code 7050.5 dictates that any discoveries
of human skeletal material shall be immediately reported to the County Coroner and
excavation halted until the coroner has determined the nature of the remains. If the
coroner recognizes the human remains to be those of a Native American or has reason
to believe that they are those of a Native American, he or she shall contact, by
telephone within 24 hours, the NAHC and PRC 5097.98 shall be followed.
Upon discovery of human remains, the tribal and/or archaeological monitor/
consultant/consultant shall immediately divert work at minimum of 150 feet and place
an exclusion zone around the discovery location. The monitor/consultant(s) shall then
notify the tribe, the qualified lead archaeologist, and the construction manager who
will call the coroner. Work shall continue to be diverted while the coroner determines
whether the remains are human and subsequently Native American. The discovery is
to be kept confidential and secure to prevent any further disturbance. If the finds are
determined to be Native American, the coroner shall notify the NAHC as mandated
by State law, who will then appoint a Most Likely Descendent (MLD). If the
Gabrieleño Band of Mission Indians – Kizh Nation is designated MLD, the Koo-nas-
gna Burial Policy shall be implemented. To the tribe, the term “human remains”
encompasses more than human bones. In ancient, as well as, historic times, tribal
traditions included, but were not limited to, the preparation of the soil for burial, the
burial of funerary objects with the deceased, and the ceremonial burning of human
remains. The prepared soil and cremation soils are to be treated in the same manner
as bone fragments that remain intact. Associated funerary objects are objects that, as
part of the death rite or ceremony of a culture, are reasonably believed to have been
placed with individual human remains either at the time of death or later; other items
Artis Senior Housing Project
Draft Initial Study Page 102 April 2020
made exclusively for burial purposes or to contain human remains can also be
considered as associated funerary objects.
Prior to the continuation of ground disturbing activities, the land owner shall arrange
a designated site location within the footprint of the Project for the respectful reburial
of the human remains and/or ceremonial objects. In the case where discovered human
remains cannot be fully documented and recovered on the same day, the remains shall
be covered with muslin cloth and a steel plate that can be moved by heavy equipment
placed over the excavation opening to protect the remains. If this type of steel plate is
not available, a 24-hour guard should be posted outside of working hours. The tribe
shall make every effort to recommend diverting the Project and keeping the remains
in situ and protected. If the Project cannot be diverted, it may be determined that
burials shall be removed. The tribe shall work closely with the qualified archaeologist
to ensure that the excavation is treated carefully, ethically and respectfully. If data
recovery are approved by the tribe, documentation shall be taken which includes at a
minimum detailed descriptive notes and sketches. Additional types of documentation
shall be approved by the tribe for data recovery purposes. Cremations shall either be
removed in bulk or by means as necessary to ensure completely recovery of all material.
If the discovery of human remains includes four or more burials, the location is
considered a cemetery and a separate treatment plan shall be created. Once complete,
a final report of all activities is to be submitted to the tribe and the NAHC. The tribe
does not authorize any scientific study or the utilization of any invasive and/or
destructive diagnostics on human remains. Each occurrence of human remains and
associated funerary objects shall be stored using opaque cloth bags. All human
remains, funerary objects, sacred objects and objects of cultural patrimony shall be
removed to a secure container on site if possible. These items shall be retained and
reburied within six months of recovery. The site of reburial/repatriation shall be on
the Project Site but at a location agreed upon between the tribe and the landowner at
a site to be protected in perpetuity. There shall be no publicity regarding any cultural
materials recovered.
TCR-4 Professional Standards. Archaeological and Native American monitoring and
excavation during construction projects shall be consistent with current professional
standards. All feasible care to avoid any unnecessary disturbance, physical
modification, or separation of human remains and associated funerary objects shall be
taken. Principal personnel must meet the Secretary of Interior’s Standards for
archaeology and have a minimum of 10 years of experience as a principal investigator
working with Native American archaeological sites in Southern California. The
qualified archaeologist shall ensure that all other personnel are appropriately trained
and qualified.

Mitigated Negative Declaration (MND) for the Proposed
Artis Senior Living Care Facility
South Coast Air Quality Management District (South Coast AQMD) staff appreciates the opportunity to
comment on the above-mentioned document. The following comments include recommended revisions to
the air quality analysis and health risk assessment that the Lead Agency should include in the Final MND.
South Coast AQMD Staff’s Summary of Project Description
The Lead Agency proposes to a 44,192-square-foot senior living care facility with 80 rooms on 2.79 acres
(Proposed Project). Based on a review of Figure A-2, Project Location Map, in the MND and aerial
photographs, South Coast AQMD staff found that the Proposed Project is located immediately south of
Interstate 210 (I-210) and within 100 feet from a gasoline service station. Construction is expected to take
19 months1.
South Coast AQMD Staff’s Summary of Air Quality Analysis
In the Air Quality Analysis section, the Lead Agency quantified the Proposed Project’s construction and
operational emissions and compared those emissions to South Coast AQMD’s recommended regional and
localized air quality CEQA significance thresholds. Based on the analyses, the Lead Agency found that
the Proposed Project’s construction and operational air quality impacts would be less than significant.
South Coast AQMD Staff’s Comments
Based on reviews of the Air Quality Analysis in the MND, South Coast AQMD staff recommends that
the Lead Agency perform a mobile source health risk assessment (HRA) to disclose the potential health
risks in the Final MND, incorporate strategies to reduce exposures by senior residents to toxic air
contaminants from vehicles and trucks traveling on I-210, and protect public health of those living at the
Proposed Project. Detailed comments are provided as follows.
Health Risk Assessment (HRA) from Freeways and Other Sources of Air Pollution
1. Notwithstanding the court rulings, South Coast AQMD staff recognizes that the Lead Agencies that
approve CEQA documents retain the authority to include any additional information they deem
relevant to assessing and mitigating the environmental impacts of a project. Because of South Coast
AQMD’s concern about the potential public health impacts of siting sensitive populations within
close proximity of I-210, South Coast AQMD staff recommends that the Lead Agency review and
consider the following comments when making local planning and land use decisions.
Sensitive receptors are people that have an increased sensitivity to air pollution or environmental
contaminants. Sensitive receptors include schools, daycare centers, nursing homes, elderly care

facilities, hospitals, and residential dwelling units. As stated above, the Proposed Project will include
the operation of a senior living care facility. Based on a review of Figure A-2 in the MND, South
Coast AQMD staff found that the Proposed Project immediately south of I-210. Senior residents
living at the Proposed Project will be exposed to diesel particulate matter (DPM) emitted from
vehicles and trucks traveling on I-210. The California Air Resources Board has identified DPM as a
toxic air contaminant (TAC) based on its carcinogenic effects2. Additionally, the Proposed Project is
located within 100 feet of a gasoline service station to the west. Senior residents will also be exposed
to other TACs such as benzene. Therefore, South Coast AQMD staff recommends that the Lead
Agency consider health impacts on future senior residents living at the Proposed Project and perform
a mobile source HRA3 analysis to disclose the potential health risks in the Final MND4. This
recommendation will facilitate the purpose and goal of CEQA on public disclosure and enable
decision-makers with meaningful information to make an informed decision on project approval. It
will also foster informed public participation by providing the public with useful information that is
needed to understand the potential health risks from living in close proximity to a high-volume
freeway.
Guidance Regarding Residences Sited Near a High-Volume Freeway or Other Sources of Air
Pollution
2. To facilitate stronger collaboration between Lead Agencies and South Coast AQMD to reduce
community exposure to source-specific and cumulative air pollution impacts, South Coast AQMD
adopted the Guidance Document for Addressing Air Quality Issues in General Plans and Local
Planning in 20055. This Guidance document provides suggested policies that local governments can
use in their General Plans or through local planning to prevent or reduce potential air pollution
impacts and protect public health. In addition, guidance on siting incompatible land uses (such as
placing residential uses near freeways and gasoline service stations) can be found in the California
Air Resources Board (CARB)’s Air Quality and Land Use Handbook: A Community Health
Perspective (Handbook)6. In the Handbook, CARB recommends avoiding siting new sensitive land
uses such as the Proposed Project within 500 feet of a freeway7, and 300 feet of a large gasoline
dispensing facility (defined as a facility with a throughput of 3.6 million gallons per year or greater.)
A 50-foot separation is recommended for typical gasoline dispensing facilities8. Therefore, South
Coast AQMD staff recommends that the Lead Agency review the guidance documents when making
local planning and land use decisions.

4 South Coast AQMD has developed the CEQA significance threshold of 10 in one million for cancer risk. When South Coast
AQMD acts as the Lead Agency, South Coast AQMD staff conducts a HRA, compares the maximum cancer risk to the
threshold of 10 in one million to determine the level of significance for health risk impacts, and identifies mitigation measures
if the risk is found to be significant.

Health Risk Reduction Strategies
3. Many strategies are available to reduce exposures to DPM, including, but are not limited to, building
filtration systems with Minimum Efficiency Reporting Value (MERV) 13 or better, or in some cases,
MERV 15 or better is recommended; building design, orientation, location; vegetation barriers or
landscaping screening, etc. Enhanced filtration units are capable of reducing exposures. Installation of
enhanced filtration units can be verified during occupancy inspection prior to the issuance of an
occupancy permit.
4. Enhanced filtration systems have limitations. South Coast AQMD staff recommends that the Lead
Agency consider the limitations of the enhanced filtration. For example, in a study that South Coast
AQMD conducted to investigate filters9, a cost burden is expected to be within the range of $120 to
$240 per year to replace each filter. The initial start-up cost could substantially increase if an HVAC
system needs to be installed. In addition, because the filters would not have any effectiveness unless
the HVAC system is running, there may be increased energy costs to the residents. It is typically
assumed that the filters operate 100 percent of the time while residents are indoors, and the
environmental analysis does not generally account for the times when the residents have their
windows or doors open or are in common space areas of the project. In addition, these filters have no
ability to filter out any toxic gases from vehicle exhaust. Therefore, the presumed effectiveness and
feasibility of any filtration units should be carefully evaluated in more detail prior to assuming that
they will sufficiently alleviate exposures to toxic emissions.
5. Because of the limitations, to ensure that enhanced filters are enforceable throughout the lifetime of
the Proposed Project as well as effective in reducing exposures to DPM emissions, South Coast
AQMD staff recommends that the Lead Agency provide additional details regarding the ongoing,
regular inspection, maintenance, and monitoring of filters in the Final MND. To facilitate a good faith
effort at full disclosure and provide useful information to future sensitive receptors who will live in
close proximity to I-210 and a gasoline service station, the Lead Agency should include the following
information in the Final MND, at a minimum:
x Disclosure on potential health impacts to prospective senior residents from living in proximity to
a freeway and other sources of air pollution, and the reduced effectiveness of air filtration system
when windows are open and when senior residents are outdoor;
x Identification of the responsible implementing and enforcement agency such as the Lead Agency
for ensuring that enhanced filters are installed on-site at the Proposed Project before a permit of
occupancy is issued;
x Identification of the responsible implementing and enforcement agency such as the Lead
Agency’s building and safety inspection unit to provide periodic, regular inspection on filters;
x Provide information and guidance to the Project developer or proponent on the importance of
filter installation and ongoing maintenance;
x Provide information to the Project developer or proponent about where the MERV filers can be
purchased;
x Disclosure on increased costs for purchasing enhanced filtration systems;
x Disclosure on increased energy costs for running the HVAC system with MERV filters;
x Disclosure on recommended schedules (e.g., once a year or every six months) for replacing the
enhanced filtration units;
9This study evaluated filters rated MERV 13 or better. Accessed at: http://www.aqmd.gov/docs/default-

x Identification of the responsible entity such as residents or property management to ensure filters
are inspected for replacement and maintenance on time, if appropriate and feasible;
x Develop ongoing cost sharing strategies, if available, for replacing the enhanced filtration units;
x Set up criteria for assessing progress in installing, replacing, and maintaining the enhanced
filtration units; and
x Set up process for evaluating the effectiveness of the enhanced filtration units at the Proposed
Project.
Conclusion
Pursuant to CEQA Guidelines Section 15074, prior to approving the Proposed Project, the Lead Agency
shall consider the MND for adoption together with any comments received during the public review
process. Please provide South Coast AQMD with written responses to all comments contained herein
prior to the adoption of the Final MND. When responding to issues raised in the comments, response
should provide sufficient details giving reasons why specific comments and suggestions are not accepted.
There should be good faith, reasoned analysis in response. Conclusory statements unsupported by factual
information do not facilitate the purpose and goal of CEQA on public disclosure and are not meaningful,
informative, or useful to decision makers and the public who are interested in the Proposed Project.
South Coast AQMD staff is available to work with the Lead Agency to address any air quality questions
that may arise from this comment letter. Please contact me at lsun@aqmd.gov, should you have any
questions.

Artis Senior Housing Project
Mitigation Monitoring and Reporting Program Page 1 May 2020
I. Introduction
To ensure that the mitigation measures identified in a project’s Initial Study are implemented, the
California Environmental Quality Act (CEQA) requires the Lead Agency for a project to adopt a
program for monitoring or reporting on the measures it has imposed to mitigate or avoid significant
environmental effects. As specifically set forth in Section 15097(c) of the CEQA Guidelines, the public
agency may choose whether its program will monitor mitigation, report on mitigation, or both.
“Monitoring” is generally an ongoing or periodic process of project oversight, while “reporting”
generally consists of a written compliance review that is presented to the decision-making body or
authorized staff person.
An Initial Study/Mitigated Negative Declaration (IS/MND) has been prepared to address the Artis
Senior Housing Project’s (Project) potential environmental impacts. The evaluation of the Project
includes mitigation measures to avoid or substantially lessen potentially significant impacts to less-
than-significant levels. Specifically, the IS/MND includes mitigation measures related to the following
environmental issue areas: Biological Resources, Cultural Resources, Geology and Soils, Noise, and
Tribal Cultural Resources. This Mitigation Monitoring and Reporting Program (MMRP) is designed
to monitor implementation of these Project-specific mitigation measures.
II. Purpose
The overall intent of this MMRP is to:
x Verify compliance with mitigation measures identified in the IS/MND prepared for the
Proposed Project;
x Provide a framework to document implementation of the identified mitigation measures;
x Provide a record of mitigation requirements;
x Identify monitoring and enforcement agencies;
x Establish and clarify administrative procedures for the clearance of mitigation measures; and
x Establish the frequency and duration of monitoring.
III. Organization
As shown in Table 1, each mitigation measure for the Proposed Project is listed by environmental
issue area, with accompanying information identifying the:
x Enforcement Agency – the agency with the power to enforce the Project’s mitigation
measures.
x Monitoring Agency – the agency to which reports involving compliance and implementation
of the mitigation measures are made.
x Monitoring Phase – the phase of the Project (e.g., pre-construction, construction, architectural
coatings, occupation, etc.) during which the mitigation measure shall be monitored.
x Monitoring Frequency – the frequency at which the mitigation measure shall be monitored
during the phase identified in the prior column.
x Action Indicating Compliance – the action or actions by which the enforcement/monitoring
agency indicates that compliance with the identified mitigation measure has been determined.

BIO-2 Prior to issuance of a building permit, the applicant shall demonstrate that the Project landscaping plan and planned
construction are consistent with the City’s Tree Protection Ordinance and the Protected Tree Study. The tree protection
activities shall include the following:
1. Prior to demolition, the contractor and consulting arborist shall meet on-site to make sure tree protection zones
are established around all protected trees to be preserved and to review the goals for the tree protection plan.
2. Tree protection zone fences shall be placed around each protected tree. Fences shall be at least 4 feet tall and
constructed of chain-link fencing secured on metal posts. Where fences are not feasible (e.g., in haul routes or
areas where workers will need frequent access), soil and root protection material can be installed.
3. The contractor shall maintain the fences and/or soil protection material throughout the completion of the Project.
No staging of materials or equipment or washing out shall occur within the fenced protected zones.
4. Trees should be irrigated throughout the year. A deep watering that provides good soil moisture to a depth of 16
inches is optimal. The trees shall be deeply water once every 21 to 28 days during the summer and fall seasons
when rain is unlikely.
5. For Tree No. 49, a protected deodar cedar located on the Project Site’s Colorado Boulevard frontage, the
deadwood shall be removed to prevent the dead branches from falling. However, no reduction pruning in the
live crown of the tree is required. The tree shall be monitored for its health during the life of the Project, and
irrigation shall occur at the same frequency of the other trees.
6. The arborist shall monitor a few critical phases of the Project, including pre-demolition, to direct the installation
of protective fences and soil protection measures; grading and excavation; any utility or drainage trenching that is
required within a tree protection zone; and a final evaluation during the landscape installation phase.
7. Additional construction best practices described in the Protected Tree Report shall be implemented.

NOI-1 Prior to issuance of a Grading Permit, the Project applicant shall demonstrate, to the satisfaction of the City of
Arcadia Building Division, that the Project complies with the following:
1. Construction contracts specify that all construction equipment, fixed or mobile, shall be equipped with
properly operating and maintained mufflers and other State-required noise attenuation devices.
2. The contractor shall provide evidence that a construction staff member will be designated as a noise
disturbance coordinator and will be present on-site during construction activities. The noise disturbance
coordinator shall be responsible for responding to any local complaints about construction noise. When a
complaint is received, the noise disturbance coordinator shall notify the City within 24 hours of the complaint
and determine the cause of the noise complaint (e.g., starting too early or bad muffler) and shall implement
reasonable measures to resolve the complaint, as deemed acceptable by the Building Official (or designee).
All notices that are sent to residential units immediately surrounding the construction site and all signs posted
at the construction site shall include the contact name and the telephone number for the noise disturbance
coordinator. All necessary signage and notices shall be posted on or sent to residential units immediately
surrounding the construction site no less than two weeks prior to the start of noise-generating construction
activities on the Project Site.
3. During construction, stationary construction equipment shall be placed such that emitted noise is directed
away from sensitive noise receivers.
4. Prior to issuance of any Grading or Building Permit, the Project applicant sh all demonstrate to the
satisfaction of the Building Official (or designee) that construction noise reduction methods shall be used
where feasible. These reduction methods may include shutting off idling equipment, installing temporary
acoustic barriers around stationary construction noise sources, maximizing the distance between
construction equipment staging areas and occupied residential areas, and utilizing electric air compressors
and similar power tools.
5. Construction haul routes shall be designed to avoid noise-sensitive uses (e.g., residences and convalescent

for impacting tribal cultural resources.
TCR-2 Upon discovery of any tribal cultural or archaeological resources, construction activities shall cease in the immediate
vicinity of the find until the find can be assessed. All tribal cultural and archaeological resources unearthed by Project
construction activities shall be evaluated by the qualified archaeologist and tribal monitor/consultant approved by
the Gabrieleño Band of Mission Indians-Kizh Nation. If the resources are Native American in origin, the Gabrieleño
Band of Mission Indians-Kizh Nation shall coordinate with the landowner regarding treatment and curation of these
resources. Typically, the tribe will request preservation in place or recovery for educational purposes. Work may
continue on other parts of the Project Site while evaluation and, if necessary, additional protective mitigation takes
place (CEQA Guidelines Section15064.5 [f]). If a resource is determined by the qualified archaeologist to constitute
a “historical resource” or “unique archaeological resource,” time allotment and funding sufficient to allow for
implementation of avoidance measures, or appropriate mitigation, must be available. The treatment plan established
for the resources shall be in accordance with CEQA Guidelines Section 15064.5(f) for historical resources. For
unique archaeological resources, preservation in place is the preferred manner of treatment in accordance with PRC
Section 21083.2(b). If preservation in place is not feasible, treatment may include implementation of archaeological
data recovery excavations to remove the resource along with subsequent laboratory processing and analysis. All tribal
cultural resources shall be returned to the tribe. Any historic archaeological material that is not Native American in
origin shall be curated at a public, nonprofit institution with a research interest in the materials, such as the Natural
History Museum of Los Angeles County or the Fowler Museum, if such an institution agrees to accept the material.
If no institution accepts the archaeological material, they shall be offered to the tribe or a local school or historical
society in the area for educational purposes.

ceremonial burning of human remains. The prepared soil and cremation soils are to be treated in the same manner
as bone fragments that remain intact. Associated funerary objects are objects that, as part of the death rite or
ceremony of a culture, are reasonably believed to have been placed with individual human remains either at the time
of death or later; other items made exclusively for burial purposes or to contain human remains can also be
considered as associated funerary objects.
Prior to the continuation of ground disturbing activities, the land owner shall arrange a designated site location within
the footprint of the Project for the respectful reburial of the human remains and/or ceremonial objects. In the case
where discovered human remains cannot be fully documented and recovered on the same day, the remains shall be
covered with muslin cloth and a steel plate that can be moved by heavy equipment placed over the excavation
opening to protect the remains. If this type of steel plate is not available, a 24-hour guard should be posted outside
of working hours. The tribe shall make every effort to recommend diverting the Project and keeping the remains in
situ and protected. If the Project cannot be diverted, it may be determined that burials shall be removed. The tribe
shall work closely with the qualified archaeologist to ensure that the excavation is treated carefully, ethically and
respectfully. If data recovery are approved by the tribe, documentation shall be taken which includes at a minimum
detailed descriptive notes and sketches. Additional types of documentation shall be approved by the tribe for data
recovery purposes. Cremations shall either be removed in bulk or by means as necessary to ensure completely
recovery of all material. If the discovery of human remains includes four or more burials, the location is considered
a cemetery and a separate treatment plan shall be created. Once complete, a final report of all activities is to be
submitted to the tribe and the NAHC. The tribe does not authorize any scientific study or the utilization of any
invasive and/or destructive diagnostics on human remains. Each occurrence of human remains and associated
funerary objects shall be stored using opaque cloth bags. All human remains, funerary objects, sacred objects and
objects of cultural patrimony shall be removed to a secure container on site if possible. These items shall be retained
and reburied within six months of recovery. The site of reburial/repatriation shall be on the Project Site but at a
location agreed upon between the tribe and the landowner at a site to be protected in perpetuity. There shall be no
publicity regarding any cultural materials recovered.
TCR-4 Archaeological and Native American monitoring and excavation during construction projects shall be consistent
with current professional standards. All feasible care to avoid any unnecessary disturbance, physical modification, or
separation of human remains and associated funerary objects shall be taken. Principal personnel must meet the
Secretary of Interior’s Standards for archaeology and have a minimum of 10 years of experience as a principal
investigator working with Native American archaeological sites in Southern California. The qualified archaeologist
shall ensure that all other personnel are appropriately trained and qualified.

To Whom It May Concern:
I am a resident of The Santa Anita Village community in Arcadia. Our residence is close to the proposed project The
Ivy Arcadia, at the former Coco's restaurant location.
I am writing to express my concerns with the proposed changes to the project since initial approval. The added
square footage, especially the newly proposed 3 story plan, will have significant undesirable effects to our
community. The added story will direct invade our privacy, allowing viewing into our backyards and houses. In
addition, this will block our view of the mountains, which we cherish. Furthermore, the added traffic would pose
safety issues to our community. Indirectly, the combination of these factors will impact the value of our homes.
We oppose these new changes wholeheartedly. We hope the planning office will take our concerns into account and
urge you to abolish these new changes.

Subject:The Ivy Arcadia - Revised Proposal
Date:Sunday, June 2, 2024 8:49:45 AM
CAUTION: This email originated from outside your organization. Exercise caution when opening attachments or
clicking links, especially from unknown senders.
Dear Mr. Arreola,
My name is James Wheeler. I am a resident of the City and my residence shares a boundary with the above project
which is designated to occupy the site of the former Coco's restaurant.
I have recently been made aware of the Developer's proposal to increase the size, scale and scope of The Ivy
Arcadia project to a size far exceeding that of the original proposal approved by the City Council in 2020. I want to
express my concern about the proposed revisions and communicate both my opposition to the revised project and
desire that the Planning Commission and City Council reject the recommendation to proceed.
My concern is that the sum of the proposed changes, but particularly the addition of a third story to the building,
will diminish privacy for surrounding residents and I, force a lifestyle change upon my family and others, take away
mountain views, create excessive noise from workers, visitors and emergency vehicle traffic, and diminish property
values. I also want to highlight the following specific concerns as I do not find statements made by the Developer
about the revised proposal to be credible.
Per the City's website, the revised proposal will increase the building's size from approximately 44,000 square feet
to 107,000 sqft, an increase of 143%. Beds will increase from approximately 80 to 114, an increase of 42%, and
parking spots from 58 to 70, an increase of 20%. The property will increase in height from 37 feet to over 50 feet,
as viewed from the South portion of the parcel. 50 staff members will offer services 24 hours. The Developer has
said the project "does not pencil out" if scaled down and changes to the proposal will be "too costly". However,
most of the added square footage is planned for on-site amenities which will sit vacant much of the time the building
is open. I find the proposal and scale is excessive when comparing the 143% increase in square footage against a
meager 42% increase in beds.
Further, given the topography of the building site, the proposed three story building will sit uphill of surrounding
single-story residences. The height of the building combined with the lower elevations of surrounding residences
will cause the building to tower over the neighborhood and compromise the neighborhood's aesthetics. I believe
zoning guidelines generally require a graded transition from lower to higher-height buildings. This new proposal
falls short of these guidelines, and it is not plausible that the three story building will be compatible with the look
and "feel" of the surrounding single-story homes, as the Developer has suggested. The height difference will be
stark. Consider the example of the Dunn-Edwards paint store at Michillinda and Colorado against the surrounding
area. I estimate the relative final height of the proposed three story building from my own backyard will exceed 60
feet.
The Developer has said the proposed height of the new building is the same as that originally approved in 2020.
This is not fully correct. In fact, the Planning Commisioner, Mr. Tsoi, pushed back against the Developer during the
Commision's May 14, 2024 meeting and stated his belief that the building will be higher than described given the
building's position on the lot and the lot's topography relative to the surrounding residences. He urged the
Developer to recalculate the building's height, inclusive of the proposed grade changes. Again, I estimate the
relative height of the proposed three story building from my own backyard will exceed 60 feet, not 40 feet as
claimed.
The Developer has stated they will expand green spaces to buffer the taller building from the neighborhood, but
their submitted plans do not reflect this. In fact, the Developer plans to remove trees along property lines to the
East and South which will make the building more visible to those surrounding residences.
The Developer has talked about building taller block walls to lessen the impact of the building's presence, but has
also spoke of hauling in tons of soil to flatten and raise the building site. I am not clear as to how raising the level of
the lot and building taller block walls will benefit the neighbors. There has been no mention of the height of the
proposed walls or what we neighbors will see when we look out our windows, but I imagine a 12' foot block wall
instead of the 6' walls we now have.
The Developer has stated the building will not obstruct residents' mountain views because residents cannot see the
mountains from their properties anyway. This is not true. I can see the mountains from my backyard without
problem. Constructing a taller building and increasing the height of block walls will certainly block the views my
neighbors and I currently have.
The Developer has stated they will amend the interior layout of the building such that South and East facing units /
rooms, specifically those on the second and third floors, will be turned inward and windowed corridors built along
the building's perimeter to prevent Ivy residents from having direct views into backyards and windows of
surrounding residences. This statement has not been offered in writing, hence the interior looking layout cannot be
guaranteed. Furthermore, the idea of the windowed corridors was haphazardly discussed at the May 14 Planning
Commission Meeting, but no details were given. And, residents walking the external corridors can still peer through
the windows into surrounding residences, especially given the increased building height.
The Developer has stated they have spoken to Lower Rancho HOA leadership and members who expressed
"excitement for the project". In fact, many, if not all, of the residences impacted by the proposal are not included in
the HOA and were not aware of the proposed design change until recently, nor are we excited about it. The
Developer made no effort to contact those directly impacted by the change until after we residents provided public
comment during the Planning Commission's May 14, 2024 meeting. Since then, the Developer has been aggressive
in its attempts to meet with local home owners and sway opinion toward approval of the project by offering "free"
renderings of the property from their backyards, and promises to mitigate concerns by adding trees, higher block
walls, etc. None of this has been offered in writing, hence cannot be guaranteed.
The Developer has created additional parking spaces on the property by repositioning them along the East and South
sides of the lot's perimeter, directly behind the block wall separating the lot from surrounding residences. Given
Ivy employees will be working around the clock, and from past experiences when Coco's was open, we residents
expect a substantial increase in vehicle noise that will include (and has in the past) vehicle start ups, engines
revving, radios / music, talking / laughing, alarms, etc. at all ours of day and night. The Developer attempted to
shift accountability for the parking lot layout and claimed the layout was due to "City requirements" rather than a
result of the Developer's own desire to increase square footage and bed count. I believe the Developer did not
consider the parking impact to surrounding residents and, in fact, could have shifted planned parking spaces more to
the North and West perimeters of the lot, and along the North and West sides of the building.
In summary, I object to the plan revision and increased height of the proposed building (3 stories) for the reasons
described above, and hope both the Planning Commission and City Council rescind their support of the revised
project by rejecting the revision to the original plans for the property. I and my neighbors do not support the revised
plan.
Thank you for your time and consideration,
James Wheeler

Dear Arcadia Development Services,
My name is Yue-Lan Kuo and I currently reside at 1159 Altura Terrace in Arcadia. It has recently come to my
attention that there has been a proposal to increase the building size of the planned assisted living care facility that
will be located on 1150 W. Colorado Boulevard.
I am writing to express my concern regarding this proposal. The increase in building size will likely result in
increased noise and traffic in the neighborhood. Additionally, the increase in building height may allow the building
a direct view into our backyard and house, reducing our privacy.
My neighbors have also reached out and expressed similar concerns. Please reconsider this proposal as it may lower
the quality of living of existing residents.
Thank you,

Folks,
We have sent the attached letter to the Planning Commission. I write to you separately to
speak with a bit more candor.
It is 2024. You all know by now that a local agency cannot use the bases listed in these
proposed findings to justify denying this project. By preparing this draft, you are marching the
City toward litigation. The better course—and the only lawful one—is to simply advise the
Commission that there is way for you to draft findings of denial that are consistent with your
professional duties to ensure that the City acts lawfully. I really hope you consider saying as
much this evening.

RE: The Ivy Arcadia (1150 W. Colorado Blvd.)
To the Planning Commission:
Californians for Homeownership is a 501(c)(3) organization devoted to using legal tools
to address California’s housing crisis. We are writing regarding the Ivy Arcadia project. The
City’s approval of this project is governed by the Housing Accountability Act, Government Code
Section 65589.5. For the purposes of Government Code Section 65589.5(k)(2), this letter
constitutes our written comments on the project.
The Housing Accountability Act generally requires the City to approve a housing
development project unless the project fails to comply with “applicable, objective general plan,
zoning, and subdivision standards and criteria, including design review standards, in effect at the
time that the application was deemed complete.” Gov. Code § 65589.5(j)(1). To count as
“objective,” a standard must “involve[e] no personal or subjective judgment by a public official
and be[] uniformly verifiable by reference to an external and uniform benchmark or criterion
available and knowable by both the development applicant or proponent and the public official.”
Gov. Code § 65589.5(h)(8). In making this determination, the City must approve the project if the
evidence “would allow a reasonable person to conclude” that the project met the relevant standard.
Gov. Code § 65589.5(f)(4). Projects subject to modified standards pursuant to a density bonus are
judged against the City’s standards as modified. Gov. Code § 65589.5(j)(3).
The City is subject to strict timing requirements under the Act. If the City desires to find
that a project is inconsistent with any of its land use standards, it must issue written findings to
that effect within 30 to 60 days after the application to develop the project is determined to be
complete. Gov. Code § 65589.5(j)(2)(A). If the City fails to do so, the project is deemed consistent
with those standards. Gov. Code § 65589.5(j)(2)(B).
If the City determines that a project is consistent with its objective standards, or a project
June 11, 2024
Page 2
is deemed consistent with such standards, but the City nevertheless proposes to reject it, it must
make written findings, supported by a preponderance of the evidence, that the project would have
a “specific, adverse impact upon the public health or safety,” meaning that the project would have
“a significant, quantifiable, direct, and unavoidable impact, based on objective, identified written
public health or safety standards, policies, or conditions as they existed on the date the application
was deemed complete.” Gov. Code § 65589.5(j)(1)(A); see Gov. Code § 65589.5(k)(1)(A)(i)(II).
Once again, “objective” means “involving no personal or subjective judgment by a public official
and being uniformly verifiable by reference to an external and uniform benchmark or criterion
available and knowable by both the development applicant or proponent and the public official.”
Gov. Code § 65589.5(h)(8).
Even if the City identifies legally sufficient health and safety concerns about a project, it
may only reject the project if “[t]here is no feasible method to satisfactorily mitigate or avoid the
adverse impact . . . other than the disapproval of the housing development project . . . .” Gov.
Code § 65589.5(j)(1)(B). Thus, before rejecting a project, the City must consider all reasonable
measures that could be used to mitigate the impact at issue.
For projects that provide housing for lower-income families, the Act is even more
restrictive. In many cases, the City must approve such a project even if it fails to meet the City’s
objective land use standards. See Gov. Code § 65589.5(d).
These provisions apply to the full range of housing types, including single-family homes,
market-rate multifamily projects, and mixed-use developments. Gov. Code § 65589.5(h)(2); see
Honchariw v. Cty. of Stanislaus, 200 Cal. App. 4th 1066, 1074-76 (2011). And the Legislature
has directed that the Act be “interpreted and implemented in a manner to afford the fullest possible
weight to the interest of, and the approval and provision of, housing.” Gov. Code
§ 65589.5(a)(2)(L).
When a locality rejects or downsizes a housing development project without complying
with the rules described above, the action may be challenged in court in a writ under Code of Civil
Procedure Section 1094.5. Gov. Code § 65589.5(m). The legislature has significantly reformed
this process over the last few years in an effort to increase compliance. Today, the law provides a
private right of action to non-profit organizations like Californians for Homeownership. Gov.
Code § 65589.5(k). A non-profit organization can sue without the involvement or approval of the
project applicant, to protect the public’s interest in the development of new housing. A locality
that is sued to enforce Section 65589.5 must prepare the administrative record itself, at its own
expense, within 30 days after service of the petition. Gov. Code § 65589.5(m). And if an
enforcement lawsuit brought by a non-profit organization is successful, the locality must pay the
organization’s attorneys’ fees. Gov. Code § 65589.5(k)(2). In certain cases, the court will also
impose fines that start at $10,000 per proposed housing unit. Gov. Code § 65589.5(k)(1)(B)(i).
In recent years, there have been a number of successful lawsuits to enforce these rules:
x In Honchariw, 200 Cal. App. 4th 1066, the Court of Appeal vacated the County of
Stanislaus’s denial of an application to subdivide a parcel into eight lots for the
June 11, 2024
Page 3
development of market-rate housing. The court held that the county did not identify
any objective standards that the proposed subdivision would not meet, and therefore
violated the Housing Accountability Act in denying the application.
x In Eden Housing, Inc. v. Town of Los Gatos, Santa Clara County Superior Court
Case No. 16CV300733, the court determined that Los Gatos had improperly denied
a subdivision application based on subjective factors. The court found that the
factors cited by the town, such as the quality of the site design, the unit mix, and
the anticipated cost of the units, were not objective because they did not refer to
specific, mandatory criteria to which the applicant could conform.
x San Francisco Bay Area Renters Federation v. Berkeley City Council, Alameda
County Superior Court Case No. RG16834448, was the final in a series of cases
relating to Berkeley’s denial of an application to build three single family homes
and its pretextual denial of a demolition permit to enable the project. The Court
ordered the city to approve the project and to pay $44,000 in attorneys’ fees.
x In 40 Main Street Offices v. City of Los Altos, Santa Clara County Superior Court
Consolidated Case Nos. 19CV349845 & 19CV350422, the court determined that
the Los Altos violated the Housing Accountability Act, among other state housing
laws, by failing to identify objective land use criteria to justify denying a mixed-
use residential and commercial project. The City was ultimately forced to pay
approximately $1 million in delay compensation and attorneys’ fees in the case.
x In Californians for Homeownership v. City of Huntington Beach, Orange County
Superior Court Case No. 30-2019-01107760-CU-WM-CJC, a case brought by our
organization, the court ruled that Huntington Beach violated the Housing
Accountability Act when it rejected a 48-unit condominium project based on vague
concerns about health and safety. Following the decision, the City agreed to pay
$600,000 in attorneys’ fees to our organization and two other plaintiffs.
Based on the above legal framework, state law requires the City to approve this project. If
you do not, we are likely to initiate litigation under the Housing Accountability Act.
Sincerely,
Matthew Gelfand

Re: The Ivy Arcadia Project (ADR 23-13 and CUP 23-09)
Dear Mayor Cao and City Councilmembers:
This firm represents O & I Development, LLC (“O&I”), the applicant proposing The Ivy
Arcadia project, a three-story senior assisted living/memory care facility with 100 residential
units and 114 beds. The project is proposed to be located at 1150 W. Colorado Boulevard, a
commercially zoned site located at the intersection of Colorado Boulevard and Michillinda
Avenue, two major thoroughfares within the City of Arcadia (“City”). The project will be
presented to the City Council on August 20, 2024.
I write this letter to emphasize three salient issues related to the City Council’s
consideration of the project:
1. First, O&I made noteworthy project changes and conducted significant
neighborhood outreach to address resident concerns about the project and provide
comfort that the project will not adversely impact the neighborhood. Those
revisions were in addition to the original design of the project, which was
sensitive to the surrounding community. For instance, the project proposes
setbacks far in excess of what is required by the Arcadia Municipal Code
(“AMC”).
2. Second, the proposed project is a “housing development project” subject to the
Housing Accountability Act (“HAA”). As such, the City Council cannot deny the
project – which is consistent with all applicable objective standards – unless the
agency concludes that the project would have a specific, adverse impact on the
public health or safety. (Govt. Code § 65589.5(j)(1).) The project would not result
in a specific, adverse impact on the public health or safety, and the City Council’s
discretion is limited by the HAA. (Govt. Code § 65589.5(a)(3) [HAA expressly
states that “the conditions that would have a specific, adverse impact upon the
public health and safety … arise infrequently”].)

August 14, 2024

3. Third, the proposed project provides a much-needed housing type within the City
and Southern California, one that serves an aging population. The units will range
from 396 square foot studios to 1,146 square foot two-bedroom units.
I. Applicant’s Project Changes
The project was first presented to the City Planning Commission on May 14, 2024, with a
staff recommendation for approval given the project’s consistency with the underlying General
Plan designation, zoning, and applicable development standards. However, ignoring that
recommendation and instead heeding the concerns expressed by a few residents, the Planning
Commission voted to recommend denial of the proposed project. The resident concerns largely
related to building height and purported view, neighborhood consistency, and privacy concerns,
but also other minor design issues.
Because staff’s recommendation was for approval, a resolution recommending denial had
to be drafted. Therefore, the project was scheduled to return to the Planning Commission on June
11, 2024. O&I, hearing the concerns expressed at the earlier hearing, immediately started
engaging surrounding residents and incorporating design changes that directly responded to
stated concerns.
First, O&I’s representative contacted residents to hear their specific concerns, including
hosting a June 3rd community meeting (with invites sent to all residences within a 300 -foot
radius of the project site). That meeting was attended by 18 homeowner s. O&I also met with
individual homeowners at their residences, discussing individual concerns and receiving
feedback.
Second, with that feedback, O&I made strategic design revisions to address resident
concerns. Those revisions include, among other things:
a. Electrical Charging Parking Spaces: The initial design included EV parking
spaces along the eastern property line. The EV spaces were relocated to the
eastern side of the building close to the pedestrian sidewalk and away from the
adjacent residences.
b. Resident Balconies. The community expressed concern that the southern and
eastern façade had multiple traditional balconies. However, the majority of the
units have “Juliette” balconies, which are an attractive architectural
embellishment rather than a traditional balcony, which functions as an outdoor
living amenity. There are only two traditional balconies on the each the southern
and eastern elevations (for a total of four traditional balconies). The remainder are
Juliette, which were specifically included for design articulation purposes and
because future residents that require assistance with daily living are unlikely to
use full balconies.

August 14, 2024
Page 3
c. Parking Spaces: The Planning Commission and residents expressed concern about
the parking spaces proposed near the southern and eastern property lines. O&I
removed six (6) spaces along the southern property line and four (4) along the
eastern property line.
d. Enhanced Green Screening: A number of residents expressed a strong desire for
green screening along their property line. The project proposes to retain 54 of the
existing trees on-site and plant 83 additional trees to enhance screening. O&I
offered to do view simulations for concerned residents, showing that the existing
and proposed landscaping would substantially screen the project from view.
e. Perimeter Wall Safety: The original project design included limited space
between the project’s proposed retaining wall and the existing wall. O&I was able
to successfully re-engineer the perimeter boundary, successfully eliminating th e
need for new retaining walls.
f. Dog Park Smell: O&I moved the dog park further away from the property line.
Also, as with all O&I’s communities, the dog park will be meticulously
maintained to ensure cleanliness and hygiene by a dedicated maintenance team.
The above demonstrates that, although the project complies with all objective
development standards, the project applicant has engaged significantly in the public process to
design a project that is sensitive to the surrounding community. However, notwithstanding
O&I’s efforts, the Planning Commission still recommended the City Council deny the proposed
project.
II. The Project Is Subject to the HAA
The proposed project is a housing development project subject to the HAA, which was
enacted to facilitate housing projects and limit arbitrary denial of such projects. (California
Renters Legal Advocacy & Education Fund v. City of San Mateo (2021) 68 Cal.App.5th 820, 844
[the HAA “cabins the discretion of a local agency to reject proposals for new housing”].) For the
HAA, a “housing development project” is a use consisting of any of the following: (1) residential
units only, (2) mixed-use developments consisting of residential and nonresidential uses with at
least 2/3rds of the square footage designated for residential uses, and (3) transitional housing or
supportive housing. (Govt. Code § 65895.5(h)(2).)
An assisted living/memory care (“ALMC”) facility is a housing devel opment project
because it consists of residential uses and ancillary supportive/service uses that, even construed
as nonresidential uses, do not take the project out of the HAA (because more than 2/3rds of the
square footage is for residential uses/units). The Civil Code defines a “senior citizen housing
development” as “a residential development developed … for, senior citizens that has at least 35
dwelling units.” (Civil Code § 51.3 [emphasis added].) A “dwelling unit” or “housing” is defined
105167\17821195v1
Arcadia City Council
August 14, 2024
Page 4
to mean “any residential accommodation other than a mobile home.” (Id. [emphasis added].)
The project is clearly a “housing development project” under the HAA.1
Because the project is a housing development project, the City may not deny or condition
a proposed project because of an alleged inconsistency with a subjective development standard.
(Id. at 831 [HAA restricts “the ability of local governments to deny an application to build
housing if the proposed project complies with general plan, zoning, and design revie w standards
that are objective”].) A standard is subjective, as opposed to objective, if it cannot be applied
without personal interpretation or subjective judgment. (Bankers Hill 150 v. City of San Diego
(2022) 74 Cal.App.5th 755, 778.)
To that end, the Planning Commission’s recommendation for denial, which was based on
subjective conclusion that the project “is not compatible in terms of design, height, and scale
with the residential land use in the vicinity” of the project site, violates the HAA. (Resolution
No. 2146.) The project is, in fact, consistent with all applicable objective standards. It does
exceed the maximum FAR of 0.50, but the project is also a Density Bonus Law (“DBL”) project
and is entitled to waiver of that standard. (Govt. Code § 65915.) Importantly, a project’s
deviation from a development standard pursuant to the DBL is not grounds to conclude that the
project is not consistent with all applicable objective standards. The HAA expressly states that
the HAA and DBL function together, and that the receipt of a density bonus, incentive,
concession, or waiver, or reduction of development standard under the DBL “shall not constitute
a valid basis on which to find a proposed housing development project is inconsistent, not in
compliance, or not in conformity” with an applicable standard. (Govt. Code § 65589.5(j)(3).)
If a housing development project complies with applicable objective standards, an agency
may only deny or reduce the density of the proposed project if it finds, by a preponderance of the
evidence in the record, that (1) the project would have a specific, adverse impact on the public
health or safety, and (2) that there is no feasible method to satisfactorily mitigate or avoid the
adverse impact identified other than denial or approval of the project at a lower density. (Govt.
Code § 65589.5(j)(1)(A); Save Lafayette v. City of Lafayette (2022) 85 Cal.App.5th 842, 850.) A
“specific, adverse” impact is defined narrowly to mean “a significant, quantifiable, direct, and
unavoidable impact, based on objective, identified written public health or safety standards,
policies, or conditions as they existed on the date the application was deemed complete.” (Id.
However, specific, adverse impacts are a rarity, a fact the HAA recognizes. (Govt. Code
§ 65589.5(a)(3) [“the conditions that would have a specific, adverse impact upon the public
health and safety … arise infrequently”].) Thus, agencies proposing to disapprove or limit
density of a proposed project face an extremely high burden.
1 The trial court in Yes In My Back Yard v. City of Simi Valley reached this exact conclusion, holding that ALMC
facility is a housing development project under the HAA. (Ventura County Superior Court Case No. 56 -2020-
00539590-CU-WM-VTA.)
105167\17821195v1
Arcadia City Council
August 14, 2024
Page 5
There is no evidence that the proposed project would, as designed to be consistent with
objective standards, would result in a specific, adverse impact on the public health and safety.
Therefore, the City’s discretion regarding the proposed project is limited by the HAA and the
City Council may not deny the project or reduce its density (or FAR here, which is used to
calculate density).
In fact, quite the opposite is true. The project is thoughtfully designed (and was
redesigned) to ensure consistency with the surrounding area, which intermingles devoutly
commercial uses (as the existing General Plan designation and zoning reflect) and residential
uses. With that thoughtful design, which is actually less intensive than other uses that could be
established by-right, the project proposes a much needed residential product that will serve aging
residents.
I appreciate your time and attention to this matter. O&I looks forward to presenting The
Ivy Arcadia project to the City Council on August 20, 2024.
Sincerely,
Cox, Castle & Nicholson LLP
