Summary
Mr. Lungren,
You have retained my consulting arborist services to provide a tree inventory and tree protection plan
for the property described as 610 Gloria Rd.Arcadia, CA 91006.You are in the permitting process of
demolishing the existing single family home and replacing it with a new single family home.
Background and assignment
Ben Lungren&Associates is a luxury home, landscaping Architectural Designing Corporation that has
been hired to design the proposed landscape and separate structures.
Mr. Lungren has requested that I provide the following arboricultural services:
1) Identify the trees and label it on the provided Topographic survey.
2) Evaluate possible effects that the proposed construction and demolition may have on the trees
that will remain.
3) Provide a tree protection plan and make recommendations that will reduce the possibility of
harm to all trees that are to remain.
The following report is based on my analysis of the site plan provided to me by you via email,my site
physical visit to the property, and information provided by you. For the purpose of this report I will refer
to these trees as Trees# 1 thru#20.

General Tree Protection Plan
1) Avoid damaging the roots,stem,and branches with mechanical and manual equipment.
2) Avoid soil compaction by prohibiting the use of heavy equipment such as backhoes and bobcats under the
tree drip line.
3) Do not store or park tools,equipment,vehicles,or chemicals under the tree drip line.
4) Avoid washing of equipment and tools such as wheel barrels,shovels,and mechanical motors under the
tree drip line.
5) Prevent flooding and pooling of service water under the drip line.
6) Avoid cutting tree roots whenever possible.This can sometimes be accomplished by bridging roots,
tunneling,or radial trenching. If roots must be cut use a sharp tool that will make a clean flush cut and not
tear the roots.If possible all digging under the tree drip line should be done manually to avoid tearing out
of roots.
7) Place a protective bather or temporary fencing around as much of the drip line of the tree trunk as
possible while allowing for the proposed work to be done.
8) During summer months(June thru October)deep water the trees once a month to keep them healthy until
irrigation can be installed.
9) Construction personnel should be briefed on the importance of the guidelines before construction begins
and reminded of it during tailgate meetings and as necessary.A printed copy should be posted where
employees can be reminded of it.

Tree#1 protection Plan (Camphor)
a) Structural excavation and over-excavation: The tree will not be impacted by any structural excavations due
to the long distance between the trunk and foundations of all structures.
b) New walls,walkways or alternatives: There will be no new walls erected in the vicinity of this tree.
c) New Landscaping:Tilling and soil preparation within 8 ft.of this tree shall be done manually with care to
preserve the roots. Grass shall be placed no closer than 18 inches around the entire circumference of the
tree trunk.
d) New Sprinklers:No broadcast trenching shall be allowed within 8 ft.of all sides of the tree trunk.
Alternatives can sometimes be accomplished by radial trenching,Tunneling under roots,and above ground
drip systems.
e) Canopy pruning:no canopy pruning will be required to complete this project.
f) Root pruning:all roots within 8 ft.from the tree trunk on all sides shall be preserved.
g) Maintenance: During the hot summer and fall months the tree shall be watered as needed until the
sprinkler system is installed and working.
h) Encroachment impacts:This project is expected to have a minimal impact on the short or long term health
of this tree and it is expected to survive if the protection recommendations are followed and adhered to.

Tree#2 Protection Plan (Holly Oak)
a) Structural excavation and over-excavation: The impact to the Oak roots from the excavations for the
living room and suite 1 is expected to be minimal because excavations are very close to the existing
home foundations.
b) New walls,walkways or alternatives: There will be no new walls erected in the vicinity of this tree.
c) New Landscaping:Tilling and soil preparation within 15 ft.of this tree shall be done manually with care
to preserve the roots. Grass shall be placed no closer than 18 inches around the entire circumference of
the tree trunk.
d) New Sprinklers:No broadcast trenching shall be allowed within 15 ft.of all sides of the tree trunk.
Alternatives can sometimes be accomplished by radial trenching,Tunneling under roots,and above
ground drip systems.
e) Canopy pruning:Some moderate raising of the lower canopy may be required for clearance purposes.
f) Root pruning:all roots within 15 ft.from the tree trunk on all sides shall be preserved.
g) Maintenance: During the hot summer and fall months the tree shall be watered as needed until the
sprinkler system is installed and working.
h) Encroachment impacts:This project is expected to have a minimal impact on the short or long term
health of this tree and it is expected to survive if the protection recommendations are followed and
adhered to.

The National Pollutant Discharge Elimination System (NPDES) is the portion of the Clean Water Act that applies to the
protection of receiving waters. Under permits from the Los Angeles Regional Water Quality Control Board (RWQCB),
certain activities are subject to RWQCB enforcement. To meet the requirements of the Los Angeles County Municipal
Separate Storm Sewer System (MS4) Permit (R4-2012-0175), minimum requirements for sediment control, erosion
control and construction activities must be implemented on each project site. Minimum requirements include:
• EROSION: Erosion from slopes and channels shall be controlled by implementing an effective combination of BMPs,
such as the limiting of grading activities during the wet season; inspecting graded areas during rain events; planting
and maintenance of vegetation on slopes; and covering erosion susceptible slopes.
• SEDIMENT CONTROL: Eroded sediments from areas disturbed by construction and from stockpiles of soil shall be
retained on site to minimize sediment transport from the site to streets, drainage facilities and/or adjacent properties
via runoff, vehicle tracking or wind.
• CONSTRUCTION MATERIALS CONTROL: Construction related materials, wastes, spills or residues shall be
retained on site to minimize transport from the site to streets, drainage facilities or adjoining properties by wind or
runoff, Runoff from equipment and vehicle washing shall be contained at construction sites unless treated to remove
sediment and pollutants.
• NON-STORM WATER RUNOFF: Non-stormwater runoff from equipment and vehicle washing and any other activity
shall be contained at the project site.
• EROSION AND SEDIMENT CONTROL PLAN (ESCP): Required for projects one acre or more. The ESCP must be
developed and certified by a Qualified SWPPP Developer(QSD).
• HILLSIDE: Construction upon slopes 25% or more requires the implementation of additional BMPs to protect slopes
and prevent erosion and sediment runoff.
Minimum BMPs include:(1)Soil piles must be covered with tarps or plastic, (2) leaking equipment must be repaired immediately, (3) refueling must be
conducted away from catch basins, (4) catch basins must be protected when working nearby, (5) vacuum all concrete saw cutting, (6) never wash
concrete waste into the street,(7)keep the site clean, sweep the gutters at the end of each working day and keep a trash receptacle on site.
As the engineer of record, I have selected appropriate BMPs to effectively minimize the negative impacts of this project's construction activities on
stormwater quality. The project owner and contractor are aware that the selected BMPs shall be installed, monitored, and maintained to ensure their
effectiveness. The BMPs not selected for implementation are redundant or deemed not applicable to the proposed construction activi jrt5ivrygl
