Summary
Mr. Tong,
You have retained my consulting arborist services to provide a tree inventory and protection plan for the
property described as 928 Paloma Dr. Arcadia, CA 91007. You are in the planning process of demolishing the
existing single-family home and redeveloping the property with a new two-story single-family home.
The proposed demolition and construction is expected to have minimal to moderate impact to the protected trees
that will remain due to the distance of excavations, trenches, and footings to the tree trunks. A complete tree
protection plan will be included to protect above and below ground tree parts from physical damage, soil
compaction, and chemical damage.
Background and assignment
Mr. Tong has requested that I provide the following arboricultural services.
1) Identify all trees on the property and label them on the architectural drawings as provided to the
arborist by Mr. Robert Tong.
2) Evaluate the current health of the trees and possible impacts of the proposed construction based
on the provided site plan and make recommendations.
3) Provide a tree protection plan that will help ensure the short and long term health of the trees that
will remain during and after construction activities are completed.
The following report is based on my site visit on January 3, 2020 and my analysis of the trees, site plan,
and surrounding landscape. For the purpose of this report I will address these trees as Trees # 1 thru 18.

Reduced branch
Tree # 3 Final Analysis
• This tree poses a moderate probability of failure due to the trunk lean combined with the root
loss and root cavity. Decay is also likely in the main trunk where the termites are visible and
there is an increased probability of branch failure at these points.
• The Bacterial fireblight has also affected the canopy by creating deadwood in the outer tips and
tends to increase in intensity sometimes killing the tree. There is no chemical cure for this.
Bacterial fireblight is hard to eradicate even by cutting it off because it contaminates pruning
tools and it redistributed on fresh healthy wood with every cut.
• Aesthetically the leaning trunk and Bacterial fireblight is also very unsightly for the location in
the front yard.
Mitigation Measures
• The tree lean can be mitigated by installing a large metal brace in the ground with concrete
filling and propping it against the trunk under the lean, The post will also add to the negative
aesthetic properties of this tree and will not address the decaying cavities in the branches that
have termites.
Recommendation Tree # 3
• Based on the above-mentioned tree defects and circumstances it is my opinion that for safety
and aesthetic purposes that this tree be removed and replaced with a tree in an appropriate
location that will be healthy, thrive, and add aesthetic value to the property and neighborhood.

Trees # 6 (facing west)
It appears that the utility company has removed all of the lateral branches to the trunk for line clearance. Other
large branches have been either removed or failed due to the lost canopy from the trimming. Redwood trees rarely
or never recover from this trimming because the new branches that re-sprout grow vertically up against the trunk
instead of spreading at a 9-degree angle to the tree trunk. The other impediment to recovery of the canopy is that
the utility company will continue to cut it away due to mandatory fire clearance away from the utility lines.

Tree # 6 Final Analysis
• This tree does not pose a hazard of failure or safety hazard.
• The trimming of this tree has severely altered its natural appearance and it now looks like a rat’s
tail buried into the ground. There is maybe 3 of the original 15 to 20 scaffold branches left on the
tree and the rest are water sprouts that grow vertically against the tree trunk.
Mitigation Measures
• Because the original scaffold branches are gone and because the utility company will continue to
cut it to the trunk there is no reasonable mitigation to restore this tree to an acceptable
aesthetically pleasing specimen tree.
Recommendation Tree # 6
• Based on the above-mentioned tree defects and circumstances it is my opinion that for aesthetic
purposes that this tree be removed and replaced with a tree in an appropriate location that will
be healthy, thrive, and add aesthetic value to the property and neighborhood.

General Tree Protection Guidelines
1) Avoid damaging the roots, stem, and branches with mechanical and manual equipment. No roots shall be
severed within the Tree Protection Zone TPZ which is the same as the area within the Tree Protection Fencing
“TPF.” Roots greater than two inches in diameter outside of the TPZ shall be cleanly severed with a sharp
tool such as a hand saw or manual pruners.
2) Avoid soil compaction by prohibiting the use of heavy equipment such as backhoes and bobcats under the
tree drip line. If access within the TPZ is required during the construction process, the route shall be covered
in a 6 inch layer of mulch in the TPZ and the area shall be aerated and fertilized at the conclusion of
construction.
3) Do not store or park tools, equipment, vehicles, or chemicals under the tree drip line. No equipment or
debris of any kind shall be placed within the TPZ. No fuel, paint, solvent oil, thinner, asphalt, cement, grout,
or any other construction chemical shall be stored or allowed in any manner to enter within the TPZ.
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. Grade changes that will flood the TPZ are
prohibited unless a drainage plan is implemented. No grade changes within the TPZ shall be allowed.
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.
Roots outside of the TPZ may be cleanly severed vertically with a sharp garden tool.
7) Do not raise or lower the grade within the tree protection zone of any protected trees unless approved by the
project arborist. Roots greater than 1 inch in diameter that are exposed or damaged shall be cut with a sharp
tool such as a hand saw, pruners, or loppers and covered with soil in conformance to industry standards. If
any work is required within the TPZ the Arborist shall be consulted previous to beginning. The Arborist shall
be contacted as soon as possible to arrange for a timely inspection and prevent delays.
Robert Tong 928 Paloma Dr. Arcadia, CA 91007 May 3, 2020
Javier Cabral / Consulting Arborist Pg. # 30
8) Place a protective barrier or temporary fencing as directed by the consulting arborist in the diagram below.
The protection fencing shall be in place before demolition begins and shall only be removed or reduced
when all heavy equipment such as back-hoes, bobcats, loaders, and other heavy equipment with tires
and tracks will not be required. Fencing can be adjusted or sections reduced or removed as the project
advances into the landscaping phases of the project. The consulting arborist shall be contacted if there are
doubts about the placement or removal of fencing.
9) Landscape preparation & excavation within the TPZ shall be limited to the use of hand tools and small
hand-held power tools and shall not be of a depth that could cause root damage. No attachments or wires
other than those of a protective or non-damaging method shall be attached to a protected tree.
10) 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.
11) All protected trees shall be watered before, during, and after construction as needed to prevent drought
stress and tree death until sprinklers have been installed and are functional.

Tree # 7 Glossy privet Protection Details
a) Structural excavation and over-excavation: Structural Excavation: This tree will be will not be
impacted by any structural excavations due to the significant distance of the tree to all structural
foundations. There are no structures anywhere near the drip line
b) Driveway: This new driveway is at a distance that the impact is expected to be zero.
c) New Landscaping: The soil tilling for the proposed lawn adjacent this tree is expected to have minimal
impact to this tree. No plants shall be planted closer than 3 ft. from all sides of the tree trunk and
planting holes shall be relocated if a root greater than 2 inches are encountered and must be severed
within 8 ft. of the tree trunk. Mulch shall be kept 6 in. away from the trunk on all sides.
d) New Sprinklers: No broadcast trenching shall be done within 6 ft. of this tree. Sprinklers for the lawn
shall be designed so that they do not wet the tree trunk on all sides.
e) Canopy pruning: No pruning will be required to complete the proposed construction project as this
tree was recently pruned.
f) Root pruning: Roots larger than 2 inches 6 ft. or more from the tree can be severed with a sharp tool
that will make a vertical and sharp clean cut.
g) Protection Fencing: shall consist of 6 ft. high chain-link free-standing panels or attached to posts
hammered into the soil and shall be in place before any works begins including demolition. All
protection fencing may be removed or reduced when all heavy equipment and major construction is
completed and landscaping is ready to be installed.
h) Maintenance: During the hot summer months the tree shall be watered as needed until the sprinkler
system is installed and working.
i) 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 in good health if the protection recommendations are
followed and adhered to.

Tree # 14 Xylosma Protection Details
a) Structural excavation and over-excavation: Structural Excavation: This Xylosma tree is expected to be
moderately impacted as it is 42 inches to the existing house. The proposed new house is approximately
7 ft. Demolition and the excavation and construction of the new footing will be especially important in
its survival. Demolition shall be done with great care to prevent pulling and tearing roots out of the
ground with large excavators. The new foundation should be built without an over-excavation or with
minimal excavation to preserve as much of the roots as possible. If the demolition and excavation is
done as recommended by the arborist it is expected that the loss of roots will be minimal to a
maximum of approximately 10 to 20 percent. The reason for this is because it is likely that there are no
roots east of the existing foundation as the existing foundation would have contained them between
the property line wall and existing house footing. The Arborist shall be present during the demolition
of the existing foundation next to the tree monitor work and to minimize root damage.
b) New Planter Wall: The proposed new planter wall adjacent this tree approximately 2 ft. shall be built at
grade and the concrete walkway excavated no deeper than 4 inches. The arborist shall be present
during the grading for the walkway and planter wall.
c) New Landscaping: The proposed new 24-inch box Carolina cherry trees within 10 ft. on both sides of
the tree trunk shall be replaced with 15-gallon containers to minimize hole size and no plants shall be
planted within 5 ft. of the tree trunk on both sides. This will minimize the danger of severing roots west
of the tree trunk since root disturbance is expected to be moderate on the east side of the trunk.
d) New Sprinklers: No broadcast trenching shall be done within 5 ft. of this Oak tree. Sprinklers for the
lawn shall be designed so that they do not wet the tree trunk on all sides.
e) Canopy pruning: Some pruning may be required for structural clearance on the east side of the tree
canopy. Pruning shall be done to International Society of Arboricultural ANSI A300 Pruning Standards.
Robert Tong 928 Paloma Dr. Arcadia, CA 91007 May 3, 2020
Javier Cabral / Consulting Arborist Pg. # 35
f) Root pruning: No plants shall be planted closer than 3 ft. from all sides of the tree trunk and planting
holes shall be relocated if a root greater than 2 inches is encountered within 5 ft., of the tree trunk on
all sides.
g) Protection Fencing: shall consist of 6 ft. high chain-link free-standing panels and shall be in place before
any works begins including demolition. All protection fencing may be removed or reduced when all
heavy equipment and major construction is completed, and landscaping is ready to be installed.
h) Maintenance: During the hot summer months the tree shall be watered as needed until the sprinkler
system is installed and working.
i) Encroachment impacts: This project is expected to have a moderate impact on the short- and long-
term health of this tree and it is expected to survive in good health if the protection recommendations
are followed and adhered to.

Certificate of Performance & Limiting Conditions
I Javier Cabral certify the following:
• No warranty is made, expressed or implied, that problems or deficiencies of the trees or the property will not
occur in the future, from any cause. The Arborist shall not be responsible for damages or injuries caused by any
tree defects, and assume no responsibility for the correction of defects or tree related problems.
• The owner and client of the trees may choose to accept or disregard the recommendations of the Arborist or
seek additional advice if the owner decides not to accept the Arborists findings or recommendations.
• The Arborist has no past, present or future interest in the removal or preservation of any tree. The opinions
contained in the Arborist report are independent and objective judgements of the Arborist.
• The findings, opinions, and recommendations of the Arborist are based on based on the physical inspection of
said property. The opinions are based on knowledge, experience, and educ ation.
• The Arborist shall not be required to provide testimony, provide site monitoring, provide further documentation
for changes beyond the control of the Arborist, be deposed, or to attend any meeting without contractual
arrangements for additional fees to the Arborist.
• The Arborist assumes no responsibility for verification of ownership or location of property lines, or for any
recommendations based on inaccurate information.
• This Arborist report may not be reproduced without the expressed written pe rmission or the Arborist and the
client to whom the report was provided to. Any changes or alteration of this report invalidates the entire report.
• Arborists are tree specialists who use their education, knowledge, training and experience to examine
trees, recommend measures to enhance the beauty and health of trees, make recommendations to prevent or
minimize damage to trees during and after construction projects, and attempt to reduce the risk of living near
trees. Clients may choose to accept or disregard the recommendations of the arborist, or to seek
additional advice.
• Arborists cannot detect every condition that could possibly lead to the structural failure of a tree. Trees
are living organisms that fail in ways we do not fully understand. Conditions are often hidden within
trees and below ground. Arborists cannot guarantee that a tree will be healthy or safe under all
circumstances, or for a specified period of time. Likewise, remedial treatments, like any medicine, ca nnot
be guaranteed.
• Treatment, pruning and removal of trees may involve considerations beyond the scope of the arborist’s
services such as property boundaries, property ownership, site lines, disputes between neighbors, and
other issues. Arborists cannot take such considerations into account unless complete and accurate
information is disclosed to the arborist. An arborist should then be expected to reasonably rely upon the
completeness and accuracy of the information provided.
• Trees can be managed, but they cannot be controlled. To live near trees is to accept some degree of risk.
The only way to eliminate all risk associated with trees is to eliminate all trees.
