Most of that meeting time was dedicated to coast live oak#2 (Quercus agrifolia) as we discussed project impacts on this tree and I arrived at this conclusion/recommendation: Since#2 coast live oak is already in such poor condition, the best solution for this project is to remove and replace it with compensating new tree plantings, as Leah has shown on these drawings. 2.0 Observations & Discussion: 2.1 Coast Live Oak#2 Status Table: Coast Live Oak#2 uercus a ri olia (coast live oak) Diameter at standard 4.5 feet 26.9" Circumference at standard 4.5 feet 84.5" Height �42' Average foliage crown radius �20', but very lop-sided. Vigor rating 60% (Fair) Structure/physics rating 20% (Very Poor) Overall condition rating 35% (Poor) Structure/physical #1 problem Severely embedded-bark main crotch. Recommendation Remove/Replant per drawings 22 Although this species is a native here in the Cupertino area, this one has several serious defects, including: acutely disproportionately balanced foliage crown poised above significant problems— suppressed on the back side—with the forward side heavily weighted toward the new construction, weak main branch attachment at —6-feet above ground level, poor scaffold branch taper, numerous "elbows" (sharp branch angles), and excessive foliage branch endweights, especially in the direction of the new house. 2.2 All those problems might be fine, if this were to continue being a backyard distant from frequent use by people. The fact that this is becoming a constantly occupied area changes the risk formula rating to now being an "unacceptable level of risk of failure".

Page#3 of 4. � Ray Morneau, Arborist ISA Certified Arborist#WE-0132A 650.964.7664 3.0 Conclusions & Recommendations 3.1 Conclusion: Coast live oak#2 was not a problem as a backyard tree because the area of impact if it were to have failed was substantially unused by humans. In order for the new house to be out of the impact area, it would need to be built 40-feet away—which is unrealistic—not workable. The planting plan is so robust that it exceeds required replacements by including not only small trees but also fourteen 24-inch-box specimens: Arbutus [strawberry trees], Cercis [Redbuds], and Olea [olives]. 3.2 Recommendation: I recommend that this project be permitted to move forward as drawn with the removal of oak#2 and replacement per Sheet L-2 "Planting Plan". 4.0 Certification I certify that all the statements of fact in this report are true, complete, and correct to the best of my knowledge, ability, and belief, and are made in good faith.
