Re: Dead Tree Removals at 10900 North Tantau Avenue, Cupertino, CA
To whom it may concern,
This letter intends to address four (4) dead Sequoia sempervirens (coast redwood) located on the
southern landscaped perimeter of the 10900 N. Tantau Avenue property in Cupertino, California.
Please see Exhibit 1.1 for the relative locations of the subject trees indicated as white/red dots, and
for the location of the replacement trees. The trees are dead and will need to be removed.
Metrics for the dead trees are found in the following table:
The trees were determined to be dead (see Exhibit 1.2) due to their extensive brown foliage, complete
lack of green foliage, and brittle needles. A live evergreen tree, such as a coast redwood, should be
green throughout the year. It is possible that the redwoods succumbed to Botryosheria dothedia
(redwood canker) as the species is host to this disease. When a redwood becomes water -stressed,
they are highly susceptible to this disease.
Removal of dead trees 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 trees 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 are four (4) 36 -
inch box coast redwoods in the same location as the proposed removals.
Please review this information and contact me with any questions or concerns regarding the
information provided in this letter.
Sincerely,
Samuel Oakley
