14.18.010 Purpose.
In enacting this chapter, the City of Cupertino recognizes the substantial economic,
environmental and aesthetic importance of its tree population. Protected trees are considered a
valuable asset to the community. The protection of such trees in all zoning districts is intended
to preserve this valuable asset. The City finds that the preservation of protected trees, and the
protection of all trees during construction, is necessary for the best interests of the City and of
the citizens and public thereof, in order to:
A. Protect property values;
B. Assure the continuance of quality development;
88
C. Protect aesthetic and scenic beauty;
D. Assist in the absorption of rain waters, thereby preventing erosion of top soil, protecting
against flood hazards and the risk of landslides;
E. Counteract air pollutants by protecting the known capacity of trees to produce pure
oxygen from carbon dioxide;
F. Maintain the climatic balance (e.g., provide shade);
G. Help decrease potential damage from wind velocities;
For the above reasons, the City finds it is in the public interest, convenience and necessity to
enact regulations controlling the care and removal of protected trees within the City in order to
retain as many trees as possible, consistent with the individual rights to develop, maintain and
enjoy their property to the fullest possible extent.

frame in which the tree(s) will reach the eventual growth size.
The tree management plan shall be approved by the authority approving the landscape plan
prior to recordation of the tree management plan. The Director of Community Development
shall review and approve the tree management plan where no landscape plan is required.
Trees that are listed to be removed in the tree management plan may be removed within the
specified time frame per the tree management plan without a tree removal permit, except for
trees designated as heritage trees. No heritage trees shall be permitted to be removed in
conjunction with an approved tree management plan.

severely limiting the use of property in a manner not typically experienced by owners of
similarly zoned and situated property, and the applicant has demonstrated to the
satisfaction of the approval authority that there are no reasonable alternatives to preserve
the tree(s).
3. That the protected tree(s) are a detriment to the subject property and cannot be

permit to determine the location of the replacement tree(s). Table A may be used as a basis for
this requirement. The person requesting the tree removal permit shall pay the cost of
purchasing, planting and maintaining the replacement trees.
B. If a replacement tree for the removal of a non‐heritage tree or tree with trunk size equal
to or less than thirty‐six inches cannot be reasonably planted on the subject property, an in‐lieu
95
tree replacement fee based upon the purchase and installation cost of the replacement tree as
determined by the Director of Community Development shall be paid to the Cityʹs tree fund to:
1. Add or replace trees on public property in the vicinity of the subject property; or
2. Add trees or landscaping on other City property.
C. For removal of a heritage tree or tree with a trunk size greater than thirty‐six inches, the

APPENDIX B
STANDARDS FOR THE PROTECTION OF TREES DURING GRADING AND
CONSTRUCTION OPERATIONS
The purpose of this appendix is to outline standards pertaining to the protection of trees
described in Section 14.18.220 of Chapter 14.18. The standards are broad. A licensed landscape
architect or International Society of Arboriculture certified arborist shall be retained to certify
the applicability of the standards and develop additional standards as necessary to ensure the
property care, maintenance, and survival of trees designated for protection.
Standards
1. A site plan shall be prepared describing the relationship of proposed grading and utility
trenching to the trees designated for preservation. Construction and grading should not
significantly raise or lower the ground level beneath tree drip lines. If the ground level is
proposed for modification beneath the drip line, the architect/arborist shall address and
mitigate the impact to the tree(s).
2. All trees to be preserved on the property and all trees adjacent to the property shall be
protected against damage during construction operations by constructing a four‐foot‐high fence
around the drip line, and armor as needed. The extent of fencing and armoring shall be
determined by the landscape architect. The tree protection shall be placed before any excavation
or grading is begun and shall be maintained in repair for the duration of the construction work.
3. No construction operations shall be carried on within the drip line area of any tree
designated to be saved except as is authorized by the Director of Community Development.
4. If trenching is required to penetrate the protection barrier for the tree, the section of
trench in the drip line shall be hand dug so as to preclude the cutting of roots. Prior to initiating
any trenching within the barrier approval by staff with consultation of an arborist shall be
completed.
5. Trees which require any degree of fill around the natural grade shall be guarded by
recognized standards of tree protection and design of tree wells.
6. The area under the drip line of the tree shall be kept clean. No construction materials nor
chemical solvents shall be stored or dumped under a tree.
7. Fires for any reason shall not be made within fifty feet of any tree selected to remain and
shall be limited in size and kept under constant surveillance.
8. The general contractor shall use a tree service licensee, as defined by California Business
and Professional Code, to prune and cut off the branches that must be removed during the
grading or construction. No branches or roots shall be cut unless at first reviewed by the
landscape architect/arborist with approval of staff.
100
9. Any damage to existing tree crowns or root systems shall be repaired immediately by an
approved tree surgeon.
10. No storage of construction materials or parking shall be permitted within the drip line
area of any tree designated to be saved.
11. Tree protection regulations shall be posted on protective fencing around trees to be
protected. (Ord. 2085, § 2 (part), 2011; Ord. 2003, 2007)
