Summary
Mr. Tsai,
You have retained my consulting arborist services to provide a tree inventory and protection plan for the
property described as 416 W Camino Real Ave Arcadia, CA 91007. You are in the planning process of
demolishing the existing single family home and redeveloping the property with a new single family home.
The proposed demolition and construction is expected to have minimal to no 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. Tsai 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 November 3, 2018 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 24.

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) Do not raise or lower the grade within the tree protection zone of any protected trees unless approved by
the project arborist.
8) Place a protective barrier 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. Protection fencing shall be 4 to 6 ft. high chain
link freestanding panels or secured to posts driven into the ground. There shall be no entry gates into the
protected zones. 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, and loaders 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) 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 # 5 Chinese elm
This young Chinese elm tree has its trunk growing directly against the property line CMU wall. This currently
15 inch diameter tree can grow to 60 inches in diameter at maturity. This is another 22.5 inches on both
sides of the tree. The future trunk expansion and root expansion will completely deface and destroy a large
section of the CMU wall. Based on the sure trunk and root expansion I recommend removal and
replacement of this tree in a location that will allow for healthy growth and trun k and root expansion..

Certificate of Performance & Arborists Disclosure Statement
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 education.
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 f or any
recommendations based on inaccurate information.
This Arborist report may not be reproduced without the expressed written permission or the Arborist and the
client to whom the report was provided to. Any changes or alteration of this report invalid ates 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, cannot 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.
