Introduction
I have been requested by the Los Gatos Community Development Department to review
the potential impacts on 6 trees associated with the construction of a Single-Family
residence at 146 Robin Way, Los Gatos.
Trees on Site
Tree #1 is a Coastal Redwood with a diameter of approximately 38”. This tree is showing
decent health and shows nice vigor located on neighboring property. It is slated to remain.
Tree #2 is a Apple tree with a diameter of approximately 12” inches with a canopy of 12’.
This tree is showing good health. This tree is proposed for removal.
Tree #3 is a Persimmon with a diameter of approximately 10”. This tree is showing good
health. It is slated to remain.
Trees #4 is an Apricot with a diameter of approximately 10” with a canopy of 10’.It is in
moderate health. This tree is proposed for removal.
Tree #5 is a Fir tree with a diameter of approximately 22” with a canopy of 15’. This tree is
proposed for removal due to proximity to power lines that are located on rear property line.
Tree #6 is a Apple tree with a diameter of approximately 7” with a canopy of 8’. Tree is in
good health. It is slated for removal.
Tree #5 requires replacement of 2 – 24” box trees for a total of 2 trees to be planted on site
before completion of the project.
Recommendation
Tree #1 is proposed to remain. The applicant is proposing removal of existing driveway and
replacing with pavers as per plan details. Tree protection in the form of fencing shall be up
and in place as far from tree trunk as is possible before construction begins.
Tree #3 is proposed to remain and shall be protected for the duration of this project.
Standard protection measures are appropriate to protect the tree during construction per
Section 29.10.1005 of the Town Code. Any excavation around the tree will be hand
digging.
Trees #5 is approved for removal as requested pending submittal of Tree removal permit
through Town Engineering office.

1. If new plant material is installed under the canopies it should be drought tolerant
materials.

3. A thin layer of mulch shall be installed beneath the unpaved area of the canopies
and maintained throughout the project.
4. The Contractor shall adhere to the Town Code relating to Protection of Trees
during construction:
Sec.29.10.1005. – Protection of trees during construction
(a) Protective tree fencing shall specify the following:
(1) Size and materials: A five (5) or six (6) foot high chain link fencing,
mounted on two-inch diameter galvanized iron posts, shall be driven into
the ground to a depth of at least two (2) feet at no more than 10-foot
spacing. For paving area that will not be demolished and when stipulated
in a tree preservation plan, posts may be supported by a concrete base.
(2) Area type to be fenced. Type I: Enclosure with chain link fencing of
either the entire drip line area or at the tree protection zone (TPZ), when
specified by a certified or consulting arborist. Type II: Enclosure for
street trees located in a planter strip: chain link fence around the entire
planter strip to the outer branches. Type III: Protection for a tree located
in a small planter cut-out only (such as downtown): orange plastic
fencing shall be wrapped around the trunk from the ground to the first
branch with 2-inch wooden boards bound securely on the outside.
Caution shall be used to avoid damaging any bark or branches.
(3) Duration of Type I, II, III fencing. Fencing shall be erected before
demolition; grading or construction begins and remain in place until final
landscaping is required. Contractor shall first obtain the approval of the
project arborist on record prior to removing a tree protection fence.
