Re: Dead Tree Removal at 10431 North De Anza Boulevard, Cupertino, CA
To whom it may concern,
This letter intends to address one (1) dead Malus ssp. (Apple) located along the property frontage
along De Anza Boulevard on the 10431 North De Anza Boulevard property in Cupertino, California.
Please see Exhibit 1.1 for the relative location of the subject tree indicated as a white/red dot, and for
the location of the replacement tree. The tree is dead and will need to be removed and replaced.
The apple tree is 10-feet tall and 10-inches in diameter at 4.5-feet above grade.
The tree was determined to be dead (see Exhibit 1.2) due to its lack of live foliage, and decaying
cambium tissue. There is only one remaining live branch in the crown, indicative of extensive crown
death. The tree likely senesced as it is was likely planted in the initial landscape installation over 30
years ago. Apple trees have a lifespan of 30 years at most in ideal conditions.
Removal of a dead tree does not require a live tree removal permit prior to its removal pursuant to
Section 14.18.140 Paragraph B of the City of Cupertino’s Municipal Code; however, a subsequent
application must be filed within five (5) working days. The tree will require replacement, selected
by the Apple arborist to ensure optimal structure, health, and no girdling roots. The selected tree will
then be trained from an early age as needed to optimize branching structure, extending the
aesthetically and structurally sound lifespan of the tree. The proposed replacement is one (1) 24-
inch box Acer palmatum at the De Anza Boulevard courtyard.
Please review this information and contact me with any questions or concerns regarding the
information provided in this letter.
Sincerely,
Samuel Oakley
