SUBJECT: ARBORIST REPORT FOR PROPERTY AT 10385 Bandley Dr, Cupertino, CA
95014
This arborist report includes the observations and assessment of one (1) protected tree
growing in a landscape area on the south side of the property. The site was visited on
Monday, July 17, 2023. The trees are dead and need to be removed before becoming
unstable.
Assignment: Review two Betula pendula (European white birch) trees growing at
10385 Bandley Dr, Cupertino, CA 95014, on the south side of the property, in a
landscape area adjacent to the sound wall. The tree is located in a grove of birch trees.
The assignment requires the following activities: visit the site, verify the tree, list the
tree species, diameter, crown radius, tree condition, impacts to the property, and
mitigation options.
Observations: The site was visited on Monday, July 17, 2023.
The tools used were a diameter tape and a screwdriver as a probe. Crown height and
radius were estimated. The maps one (1) tree was measured for trunk diameter at
approximately 4.5 feet above grade with a diameter tape. Trees were assessed and
rated for health and structure. Overall condition considering branch structure, decay,
leaf quality, vitality, dieback, lean, and other issues that affect the state of the trees.
The two trees health was determined by observing the foliage, twig growth, leaf
density, and dead branches. The structure rating was determined by observing branch
attachment, crotch structure, trunk flare, surface roots, decay, insects and diseases,
growth habit, and any physical damages. The overall condition combines the health
and the structure ratings based on the most significant needs.
The Betula pendula (European white birch) tree has declined to the point that there is
no opportunity for recovery.

Discussion: The Betula pendula (European white birch) must be removed and
replaced. One is dead, and the other is near dead and would be classified as a dead
tree per the City of Cupertino tree protection ordinance.
Conclusion: The Betula pendula (European white birch) tree shall be removed in
accordance with CHAPTER 14.18: PROTECTED TREES.
Mitigation: Plant 1 24 box Betula nigra (black birch) in the same spots where the
other trees were moved to mitigate the loss of the two trees.
