Re: Hazard Tree Removals at 10330 North Wolfe Road, Cupertino
To whom it may concern,
Arborwell has been retained to prepare an arborist letter for the commercial property at 10330 North
Wolfe Road in Cupertino, CA. This letter documents the removal of two (2) trees dead trees on
December 31, 2016. 2 total trees removed are:
Two (2) Sequoia sempervirens (Coast Redwood)
The metric description of the subject trees are in the following table:
ID Species DBH Height Spread Type of Removal
(inches) (feet) (feet)
1 Sequoia sempervirens 14 40 15 Dead
2 Sequoia sempervirens 12 30 10 Dead
Sequoia sempervirens
The individuals were next to the sound wall on the residential property. They were completely dead,
determined due to their extensive loss of foliage, severely desiccated limbs, and 100% lack of green
growth. Coast Redwoods are evergreen trees and should have a full crown throughout the entire
year.
Replacements
We understand they are considered protected trees pursuant to Section 14.18.035 of the City of
for very extreme weather events, we ask that the identified hazard and/or dead trees be granted
exemption pursuant to Section 14.18 of the City
To mitigate the removals, we propose to replace with four (4) 24-inch box Quercus agrifolia within
the parking lot, evenly spaced for maturity. This species was selected due to its drought-tolerance,
its screen-like characteristics for as a juvenile to aid in screening the wall and freeway, and its
extensive canopy at maturity. The locations have been selected to allow for full growth at maturity.
New trees will be selected to ensure optimal structure, health, and no girdling roots, and then trained
from an early age as needed to optimize branching structure which will extend the aesthetically and
structurally sound lifespan of the trees.

Conclusion
Given the elevated probability of failure, the large size of the trees, and the increased risk of a tree
damaging property or causing personal injury, we think these trees had a very high tree failure risk
and were removed. We intend to replace them immediately.
Please review this information and contact me with any questions or concerns regarding the
information provided in this letter.
