Re: Two (2) Tree Removals at 10900 North Tantau Avenue, Cupertino
To whom it may concern,
This letter documents the necessity to remove two (2) Platanus racemosa (California Sycamore)
located in various planting areas within the parking lot of the 10900 N. Tantau Avenue property in
Cupertino, CA. Their removal and replacement will serve to improve and extend the long-term
viability, robustness, and value provided to the property, the greater Apple Urban Forest, and the
City of Cupertino.
Tree 1 is 13-inches diameter at 4.5-feet above grade (DBH) and 30-feet in height. The tree has very
poor structure and poor health. The tree has living foliage within the crown only because it is
supported structurally and physiologically by 10 percent of the trunk due to a basal canker that girdles
90 percent of the trunk. Frass and debris of structural -compromising wood -eating insect is observed
in the deadwood. The tree is at an elevated risk of falling over and requires immediate removal.
Tree 2 is 10-inches diameter at DBH and 25-feet in height. The tree is dead with very poor structure.
There is also a massive canker at the base of the trunk that is compromising stability. The tree is at
an elevated risk of falling over and requires immediate removal.
We are asking to remove the trees per Section 14.18.180 (A) 1:
"That the tree or trees are irreversibly diseased, are in danger of falling, can cause potential damage
to existing or proposed essential structures, or interferes with private on -site utility services and
cannot be controlled or remedied through reasonable relocation or modification of the structure or
utility services."
recommend both trees be removed in the immediate future because the risk of falling over during
high -wind storm events is elevated. The trees will require replacement in accordance with Section
14.18.160. The proposed replacements are two (2) standard 36-inch box as the same species
(Platanus racemosa) and same location as the proposed removals. The trees will be selected by
the Apple arborist to ensure optimal structure, health, and no girdling roots.
Please review this information and contact me with any questions or concerns regarding the
information provided in this letter.
Sincerely,
C _7�_
