Case Manager
To whom it may concern,
Arborwell has been retained to prepare an arborist letter for the commercial property at 10500 North De Anza
Boulevard in Cupertino, CA. This letter documents the necessity to remove one (1) dead Scinus molle
(Peruvian Pepper Tree) located in the courtyard at 10500 N. De Anza Boulevard.
Please see Exhibit 1.1 for the relative location of the subject tree indicated as a red dot, and for the location of
the replacement tree.
Metrics for the dead tree is found in the following table:
The tree was determined to be dead (see Exhibits 1.2) due to its extensive loss of foliage, severely desiccated
limbs, and lack of any green growth. The trunk had several large pockets of visible decay. Immediate removal
is recommended. A live pepper tree should have a lush, green crown with an abundance of foliage.
Replacements
We ask that the identified dead tree be granted exemption pursuant to Section 14.18 of the City of Cupertino's
Municipal Code, and ask for your permission to proceed with the removal and replacement per this document.
To mitigate the removal, we are planning to replace with one (1) 36-inch box Quercus spp. or equivalent
drought tolerant tree species, pending availability of highest quality stock in tree nurseries per ordinance
mitigation requirements in the same location as the removal. The species determined by the Apple Arborist.
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. The new tree 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.
Conclusion
Our concern is that the property is a commercial space that has an abundance of employees occupying the area
at any given time, resulting in an elevated target value. Given that the tree is dead, contributing to an elevated
probability of failure, and the resulting increased risk of a tree falling into the drive aisle, we think it has a very
high tree failure risk and should be removed and replaced immediately.
Again, the tree listed above has been identified as a candidate for immediate removal because it is dead and
poses an increased likelihood of failure.
