= DAapjpnter and planter island. The site was visited on Thursday, June 8,
2023 and June 22, 2023. The Pinus radiata, Monterey pine, is dead and must be
removed before becoming unstable and the Ulmus parvifolia, Chinese elm growing in a
planter island, was removed as it had a limb failure that created a hazard in a high
target area.
Assignment: Review one Pinus radiata, Monterey Pine (Figure 1) tree growing in a
planter strip on the south side of the property and one Ulmus parvifolia, Chinese elm at
10450 Bubb Rd Cupertino, CA 95014, shown in Figure 3.
The assignment requires the following activities: visit the site, verify the tree, list the
tree species, diameter, crown radius, condition of the tree, impacts to the property, and
mitigation options.
Observations: The site was visited on Thursday, June 8, 2023, at about 12:00 pm. The
tree has a primary ID number per the Treeplotter application. The TreePlotter ID#
11130.
The tools used were a diameter tape and a screwdriver as a probe. Crown height and
radius were estimated. The tree on the map was measured for trunk diameter at
approximately 4.5 feet above grade with a diameter tape. The tree was assessed and
rated for health and structure, and overall condition considering branch structure,
decay, leaf quality, vitality, dieback, lean, and other issues that affect the condition of
the trees.
The tree's health condition was determined by observing the tree foliage, twig growth,
leaf density, and dead branches. The structural integrity 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 based on the most significant conditions present.
Discussion: The Pinus radiata, Monterey Pine, is dead, as shown in Figure 2. Unsure of
a specific reason for death but would suspect pitch canker and drought.
