SUBJECT: ARBORIST REPORT FOR PROPERTY AT 10385 Bandley Dr, Cupertino, CA
95014
This arborist report includes the observations and assessment of two (2) protected trees
growing in a landscape area on the south side of the property. The site was visited on
Thursday, August 24, 2023. The trees are dead and need to be removed before
becoming unstable.
Assignment: Review two 2 Betula pendula (European white birch) trees growing at
10000 Torre Ave, Cupertino, CA 95014, on the southeast side of the property, in a
landscape area.
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 Thursday, August 24, 2023.
The tools used were a diameter tape and a screwdriver as a probe. Crown height and
radius were estimated. The maps two (2) trees were 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 habits, and any physical damages. The overall condition combines the health
and the structure ratings based on the most significant needs.
The two (2) Betula pendula (European white birch) trees have declined to the point that
there is no opportunity for recovery.
Discussion: The two (2) Betula pendula (European white birch) must be removed and
replaced. Both trees are dead.
