To whom it may concern,
Arborwell has been retained to prepare an arborist letter for the commercial property at 10475
Bandley Drive in Cupertino, CA. This letter documents the necessity to remove one (1) dead
Koelreutaria paniculata (Goldenrain Tree) located in the frontage landscape. Its 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.
The tree was determined to be dead and at a high risk for failure. The tree had extensive decay in
all leaders and scaffolds limbs, and desiccated cambium tissue throughout the large diameter limbs
from top to bottom. There was cracking at the branch union of the limb that extended towards
Bandley Drive. Most of the large scaffold limbs were dead and exhibited this cracking.
Because of the condition described above, the tree was at critical risk of failure and posed an extreme
hazard to pedestrians and cars. If the tree failed, half of the crown would have been laying in the
street and the remaining dead limbs would have been out of balance. This tree should be removed
immediately.
Replacements
The tree is considered exempt pursuant to Section 14.18.150 of the City of Cupertino's Municipal
Code but requires a permit from the City's Planning Department within 5 working days from its
removal. To mitigate the removal, we are planning to replace with one (1)24-inch box Quercus spp.
or equivalent (species determined by the Apple Arborist) per ordinance mitigation requirements.
Replacement tree species will be selected for favorable characteristics whenever possible such as
drought tolerance, long lifespan, structurally sound, deep-rooted, Cupertino climate-appropriate,
onsite location-appropriate, shading value, pest resistance and overall enhanced aesthetics. New
trees will be selected by an Apple arborist to ensure optimal structure, health, and reduce the risk of
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.
Please review this information and contact me with any questions or concerns regarding the
information provided in this letter.
Sincerely,
C_7�_
