SUBJECT: A1P. ffiTeREPORT FOR PROPERTY AT: 4 Results Way, Cupertino, CA 95014
Dear,
This arborist report includes the observations and assessment of the declining pine tree located
along perimeter fence along McClellan road. The site was visited on Thursday July 1st, 2021.
Assignment: Review one declining Monterey Pine tree located at 4 Results Way Cupertino and
managed by Apple Inc.
All site information and history were provided by Jeff Walther, Silicon Valley landscape
manager. The assignment requires the following activities: visit the site, verify the trees, list the
tree species, diameters, crown radius, condition of the trees, impacts to the property, and
mitigation options.
Observations: The site was visited on Thursday, July 1st, 2021 at about 11:00 am. The tree was
not tagged with numbers, though Treeplotter was used for identification and history.
The tools used were a diameter tape, screwdriver as a probe, hammer. Crown height and radius
were estimated. The tree listed 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 health condition rating was determined by observing the tree 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 conditions present.
The rating system used for both health, structure, and overall condition is:
(0) 0% dead;
(1) 1-20% very poor/severe decline;
(2) 21-40% poor/declining;
(3) 41-60% fair;
(4) 61-80% good; and
(5) 81-100% excellent.
