DATE: June 17, 2025
TO: Honorable Mayor and City Council
FROM: Chen Suen, Fire Chief
By: Mark Krikorian, Fire Marshal
SUBJECT: ORDINANCE NO. 2405 AMENDING ARTICLE III, CHAPTER 1, PART 3
OF THE ARCADIA MUNICIPAL CODE REGARDING FIRE HAZARD
SEVERITY ZONES AND ADOPT THE FIRE HAZARD SEVERITY ZONES
(“FHSZ”) MAP
CEQA: Exempt
Recommendation: Adopt
SUMMARY
At its regular meeting of June 3, 2025, the City Council introduced Ordinance No. 2405,
amending Article III, Chapter 1, Part 3 of the Arcadia Municipal Code regarding Fire
Hazard Severity Zones (“FHSZ”). Refer to Attachment No. 1 for the full text of the
Ordinance and Attachment No. 2 for the June 3, 2025, City Council Staff Report. It is
recommended that the City Council adopt Ordinance No. 2405, amending Article III,
Chapter 1, Part 3 of the Arcadia Municipal Code regarding Fire Hazard Severity Zones
and adopt the Fire Hazard Severity Zones Map.
DISCUSSION
In 2022, Assembly Bill 221 was passed by the California Legislature and modified the
method local jurisdictions take to adopt their fire hazard severity zone map. The new bill
requires local agencies to adopt Moderate, High, and Very High FHSZ designations,
within 120 days of the Office of the State Fire Marshal’s (“OSFM”) recommendations. On
March 24, 2025, the City received the state-recommended map (Exhibit “A” – Attachment
No. 1), which must be adopted by ordinance within 120 days (by July 22, 2025).
Ordinance No. 2405 ensures Arcadia’s alignment with updated state standards for wildfire
preparedness and safety. Adoption of Ordinance No. 2405 will replace the existing Part 3,
Chapter 1, Article III of the Arcadia Municipal Code. The existing Fire Zone map adopted
in 2008 will be replaced by the proposed FHSZ map, ensuring compliance with Government
Code Section 51179.

ENVIRONMENTAL ANALYSIS
This ordinance is exempt from the California Environmental Quality Act (“CEQA”)
pursuant to Section 15308 (Actions by Regulatory Agencies for Protection of the
Environment), since the adoption of the FHSZ Map and accompanying statutory
regulations would help reduce the spread of wildfire.
Furthermore, this ordinance is not considered a project under the California
Environmental Quality Act pursuant to Sections 15060(c)(2), 15060(c)(3), and 15061,
seeing that the adoption of the Fire Hazard Severity Zone Maps will not result in a direct
or reasonably foreseeable indirect physical change in the environment.
FISCAL IMPACT
Adoption of Ordinance No. 2405 has no immediate fiscal impact to the City. Due to the
potential financial impacts of the new Zone 0 regulations on property owners, the Fire
Department will seek grant opportunities to assist with mitigation measures in reaching
compliance in the applicable zone. At this time, the Fire Department does not foresee a
need to augment staffing levels to meet additional inspection requirements. Current
inspection assignments will be adjusted to allow for focused community risk reduction
activities in the FHSZ area.
RECOMMENDATION
It is recommended that the City Council determine that this project is exempt under the
California Environmental Quality Act (“CEQA”); and adopt Ordinance No. 2405 amending
Article III, Chapter 1, Part 3 of the Arcadia Municipal Code regarding Fire Hazard Severity
Zones and adopt the Fire Hazard Severity Zones (“FHSZ”) Map.

Exhibit "A"
DATE: June 3, 2025
TO: Honorable Mayor and City Council
FROM: Chen Suen, Fire Chief
By: Mark Krikorian, Fire Marshal
SUBJECT: ORDINANCE NO. 2405 AMENDING ARTICLE III, CHAPTER 1, PART 3
OF THE ARCADIA MUNICIPAL CODE REGARDING FIRE HAZARD
SEVERITY ZONES AND ADOPT THE FIRE HAZARD SEVERITY ZONES
(“FHSZ”) MAP
CEQA: Exempt
Recommendation: Introduce
SUMMARY
In September 2021, Senate Bill 63 was passed and directed the Office of the State Fire
Marshal (“OSFM”) to identify Fire Hazard Severity Zones (“FHSZ”) across the state, to
include Moderate, High, or Very High fire zone designations. This law required OSFM to
create maps based on the severity of the potential fire hazard in each local area. The
potential for fire hazards was determined using the fuel loading, slope, fire weather, and
other factors that are major causes of wildfire spread.
OSFM released its fire hazard zone map for Arcadia on March 24, 2025 (see Exhibit “A”
–Attachment No. 1). California Government Code Section 51179 requires local
jurisdictions to adopt the FHSZ map within 120 days of receipt. To comply with the
Government Code, it is recommended that the City Council introduce Ordinance No. 2405
to amend Article III, Chapter 1, Part 3 of the Arcadia Municipal Code regarding Fire
Hazard Severity Zones and adopt the Fire Hazard Severity Zones Map.
BACKGROUND
In 1992, Assembly Bill 337, also known as the Bates Bill, mandated the identification of
Very High Fire Hazard Severity Zones by OSFM. The bill was a response to the
devastating Oakland Hills fire of 1991. Structures located within the designated zone were
subject to minimum defensible space requirements, known as the minimum space around
a structure that must be cleared or maintained to reduce the risk of damage from wildfires.
The last statewide update to the FHSZ was in 2007. This update included enhanced new
construction requirements for structures located in the FHSZ. Consequently, the City

June 3, 2025

Council approved Ordinance No. 2241 in 2008, and adopted Arcadia’s current Fire Zone
Map.
In 2022, Assembly Bill 221 was passed by the California Legislature and modified the
method of map adoption by local jurisdictions. The new bill requires local agencies
to adopt Moderate, High, and Very High FHSZ designations within 120 days of OSFM’s
recommendations. Local governments cannot downgrade state-designated hazard levels
but may increase them, if justified. On March 24, 2025, the City received the state-
recommended map (Exhibit “A” – Attachment No. 1), which must be adopted by ordinance
within 120 days (by July 22, 2025).
DISCUSSION
In Exhibit “A” of Ordinance No. 2405, the proposed FHSZ map identifies Moderate, High,
and Very High fire zones within the City of Arcadia. OSFM fire scientists and wildfire
mitigation experts developed the map using a science-based and field-tested model that
assigns a hazard score based on factors that influence fire likelihood and fire behavior.
When developing the maps, many factors are considered such as fire history, existing
and potential fuel (natural vegetation), predicted flame length, blowing embers, terrain,
and typical fire weather for the area.
It should be noted that FHSZ maps evaluate “hazard,” not “risk”. For reference, FHSZ
maps are similar to flood zone maps, where lands are described in terms of the probability
level of a particular area being inundated by floodwaters, but the maps do not contain
regulatory measures for mitigation. “Hazard” is based on the physical conditions that
create a likelihood and expected fire behavior over a 30 to 50-year period, without
considering mitigation measures such as home hardening, recent wildfire, or fuel
reduction efforts. “Risk” is the potential damage a fire can pose to the area under existing
conditions, accounting for any modifications such as fuel reduction projects, defensible
space, and ignition resistant building construction.
Though State law does not allow a local agency to decrease the FHSZ designation, a local
agency may increase the designation of a particular area, if findings can be made that it
is necessary for effective fire protection within the area (Government Code Sections
51179(b)(1) and (2)). Such discretion can allow an agency to apply Very High, High, and
Moderate designations to areas not otherwise identified in the map prepared by OSFM.
Each zone designated by the map has associated regulatory requirements. These include
FHSZ identification (i.e., Very High, High, and Moderate), home hardening construction
requirements (e.g., use of ignition resistant materials, Class A roofing, dual paned
windows, etc.), FHSZ disclosure to the buyer at time of property real estate sale, and 100-
foot vegetation defensible space clearances. In addition, Title 14 Fire Safe Regulations
and Subdivision Review, will be used to assist the community in ensuring adequate
emergency access and water supply should larger developments be proposed in the Very
High FHSZ. These requirements are summarized in Table 1 below:

Since the OSFM map did not show designations at the parcel level, several properties
were split between two different zones. The proposed ordinance includes an interpretative
note that when any parcel has more than one FHSZ designation depicted on the adopted
map, the highest FHSZ designation shall be applied to the entire parcel. For example, a
parcel containing both a High and Very High hazard designation will be administered as
Very High FHSZ. This interpretation will prevent different building and property
maintenance codes applying for different areas of one parcel. It will also prevent
confusion among staff about which standard to apply. All modifications are made in
Ordinance No. 2405 Fire Hazard Severity Zone (“FHSZ”) Maps
June 3, 2025
Page 4 of 6
accordance with the California Government Code Section 51179, ensuring that FHSZs
were not downgraded. Aside from this one interpretative adjustment, the maps are being
proposed for adoption as recommended by the OSFM.
Adoption of Ordinance No. 2405 will replace the existing Part 3, Chapter 1, Article III of the
Arcadia Municipal Code. The existing Fire Zone map adopted in 2008 will be replaced by
the proposed FHSZ map, ensuring compliance with Government Code Section 51179.
While the new maps include a greater number of parcels affected, the number of parcels
in the highest fire zone have been reduced. Table 2 below provides a comparison of the
different FHSZ zones and affected parcels:
Table 2: Parcels within the FHSZ
Parcel Designation 2008 2025
Very High 911 768
High 36 360
Moderate 37 234
Total Parcels 984 1,362
In the current map, 42 parcels are commercial property (16 High, 26 Moderate); no
commercial parcels were on the 2008 map.
Community Education and Outreach
This proposed FHSZ map is posted on the City’s website for public viewing and outreach
was undertaken to educate impacted property owners, as well as local real estate agents.
Invitations were sent to impacted property owners, who largely consist of property owners
in the Arcadia Highlands Homeowners Association, the Whispering Pines Homeowners
Association, the Santa Anita Oaks Association, and the Rancho Santa Anita Association.
Additionally, a direct mailer was sent to approximately 450 residents who do not live in an
HOA but reside between Grandview Avenue and Orange Grove Avenue in Arcadia.
Community stakeholders were invited to attend up to three townhall meetings that shared
details on the proposed maps and impacts of the corresponding changes.
Once adopted, the Fire Department will continue public education efforts to ensure that all
property owners affected by the new FHSZ map are fully informed of the new requirements
and assist them in achieving compliance. These efforts will focus on the properties within
the Very High Hazard Zone, as they will have the most stringent regulations. This is
especially true with the introduction of the new Zone 0 regulation for the Very High Hazard
Zone. This new Zone 0 regulation will require all combustible materials, including
vegetation, within five feet of structures to be removed. The specifics of the Zone 0
regulation are still in development at the state level, but it should be in effect for new
structures beginning January 1, 2026. In the meantime, existing structures will be allowed
to achieve compliance in an agreed-upon timeline between the property owner and the Fire
Department. In instances of non-compliance, the Government Code (Section 51185) allows
local agencies to fine property owners a minimum of $100, and a maximum of $500, per
Ordinance No. 2405 Fire Hazard Severity Zone (“FHSZ”) Maps

day. Historically, the Fire Department consults with the City Attorney for property
abatement, when necessary.
It is currently unclear if adoption of the FHSZ map will affect insurance rates. As stated by
the Office of the State Insurance Commissioner Ricardo Lara, these maps are intended to
assist local planning decisions, not insurance decisions. Per the OSFM, insurance
companies use risk models, which differ from hazard models that FHSZ use. The insurance
risk models consider the susceptibility of a structure to damage from fire and other short-
term factors that are not included in hazard modeling. It is unlikely that insurance risk
models would utilize FHSZs as a factor, but much of the same data used in the FHSZ model
can also be found in the insurance companies’ risk models. Of note, insurance risk models
incorporate many other factors that change more frequently than those that OSFM includes
in its hazard mapping.
ENVIRONMENTAL IMPACT
This ordinance is exempt from the California Environmental Quality Act (“CEQA”)
pursuant Section 15308 (Actions by Regulatory Agencies for Protection of the
Environment), since the adoption of the FHSZ Map and accompanying statutory
regulations would help reduce the spread of wildfire.
Furthermore, this ordinance is not considered a project under the California
Environmental Quality Act pursuant to Sections 15060(c)(2), 15060(c)(3), and 15061,
seeing that the adoption of the Fire Hazard Severity Zone Maps will not result in a direct
or reasonably foreseeable indirect physical change in the environment.
FISCAL IMPACT
Adoption of Ordinance No. 2405 has no immediate fiscal impact to the City. Due to the
potential financial impacts of the new Zone 0 regulations on property owners, the Fire
Department will seek grant opportunities to assist with mitigation measures in reaching
compliance. The Fire Department does not foresee a need to augment staffing at this
time to meet additional inspection requirements. Current inspection assignments will be
adjusted to allow for focused community risk reduction activities in the FHSZ area.
RECOMMENDATION
It is recommended that the City Council determine that this project is exempt under the
California Environmental Quality Act (“CEQA”); and introduce Ordinance No. 2405
amending Article III, Chapter 1, Part 3 of the Arcadia Municipal Code regarding Fire
Hazard Severity Zones and adopt the Fire Hazard Severity Zones (“FHSZ”) Map.
