To whom it may concern,
This letter intends to address three (3) dead Sequoia sempervirens (coast redwood) located along the
perimeter of the property along Beardon Drive on the 20705 Valley Green Drive 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 locations of the replacement trees. The trees are dead and will need to
be removed and replaced.
Two redwoods are 14-inches diameter at 4.5-feet above grade, approximately 50-feet in height and
20-feet wide. The redwood towards the rear corner of the property is 11-inches diameter at 4.5-feet
above grade, approximately 30-feet in height and 10-feet wide.
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 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 trees will require replacement, selected
by the Apple arborist to ensure optimal structure, health, and no girdling roots. The selected trees
will then be trained from an early age as needed to optimize branching structure, extending the
aesthetically and structurally sound lifespan of the trees. The proposed replacements are three (3)
36-inch box coast redwoods in the same locations 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
