An evaluation of the trees and their surrounds had been prepared by Mr. Doug Anderson, Certified Arborist, in a report dated 5-15-14. Observations I visited the site on July 10, 2014. The report prepared by Mr. Anderson is essentially accurate, with the exception that the two trees arBlue Atlas cedars (Cedrus atlantica `Glauca') not Deodar cedars (Cedrus deodara). One of these is less blue in color and more green than the other, which is a result of seedling variation, as cedars are grown from seed. For this reason, there can be considerable variation between individual trees. The leaf or needle length is the distinctive difference between Blue Atlas cedars and Deodar cedars. The two subject cedar trees are in good condition. To my knowledge, there is no significant difference between the growth and cultural characteristics between Blue Atlas cedar and Deodar cedar. These trees had severely buckled the surrounding concrete, which has been removed. Mr. Bradley Burgoyne, Administrator, stated that the Department of Health stopped the usage of this courtyard because the heaved concrete was a significant hazard. Mr. Burgoyne expressed concern about possible damage to the footing of the building. I did not see any damage to the footing, nor would I expect any given the location of the trees in relation to the building for a very long time. Prepared by Michael L. Bench, Consulting Arborist Observations July 10, 2014 1 22590 Voss Avenue Cupertino, California The interior courtyard, in which these two trees exist, is a usable space and a needed space for the provision of services by the center. Mr. Burgoyne plans to replace the surface with concrete or pavers to restore the usable space. This construction to restore the durable surface would require significant root looses to both trees, possibly rendering them unstable and hazardous. Because of the elevations of the existing soil in relation to the building, it does not appear that it would be feasible to replace the durable surface with decking, which can typically be constructed without causing significant root damage. However, decking of the synthetic composite materials installed on the soil surface inay be a feasible option. Another alternative may be the installation of artificial turf or a sport court material. In this case, approximately 2-3 inches of course sand may be used to create a more"level" surface. These tree provide very effective shade for much of the courtyard area. Recommendations 1. I suggest that the alternative materials be considered and explored prior to the removal of these trees. It appears that the majority of the courtyard could be a usable space without sacrificing safety. The addition of a layer of course sand and the possibility of shaving the top 30% of an individual root may make this option completely workable. 2. In the event that none of the alternative materials would be feasible, I would support the removal and replacement of these two subject Blue atlas cedar trees.

This letter will serve to summarize my observations and recommendations. Summary: There are two Deodora Cedar located in a 6 foot by 12 foot planter in the rear internal courtyard. The cement surrounding the courtyard has been damaged by the tree roots and has since been demolished. The trees are too large for this location and should be removed and replaced. Assignment: I have been asked to write a report supporting a tree removal permit application from the City of Cupertino. Limits of the Assignment: All observations were made from the ground. No root collar excavations were performed. Purpose & Use of the Report: This report will be used to support a tree removal permit application from the City of Cupertino. Observations: These two trees are in a 6X 12 foot planter in an interior courtyard. The courtyard is 33 feet by 33 feet square. Prepared by Doug Anderson for Bradley Burgoyne 5-15-14 Page 1 . The trees are 62 inches an� -� inches in circumference measured at inches above grade, respectively. Canopy dim�nsions measure approximately 50 feet hign and 60 foot spread. Discussion: Roots should account for approximately 1/3 of the total biomass of a tree. Root functions include water and nutrient uptake, carbohydrate storage, tree anchorage, and production of gibberellins (a hormone that promotes canopy growth). The root plate, or zone of rapid taper consists of the primary structural roots extending out from the trunk. Roots are intended to branch frequently, tapering in diameter. The root plate is the tree's primary support system during wind and weight loading. The size of the root plate is generally considered to be 3 to 6 times the trunk diameter measure at breast height, or 4.5 feet above the ground, diameter at breast height(DBH). These trees have a diameter of 19.75 and 21.3 inches, respectively. Normal root plate radius for these trees should be from 66 inches (5.5 feet) to 132 inches (11 feet). When considering root pruning in conjunction with development or improvement projects it is important to have a sense of where root pruning should occur to minimize damage to tree health and anchorage. The size of the roots to be severed is also an important consideration. The Critical Root Zone(CRZ) has been identified as a 12 inch radius for every inch of trunk diameter. To optimize tree health, no soil disturbance, grading, root pruning, or equipment operation should occur within this area. The Interior Critical Root Zone(ICRZ) halves this measurement. Root pruning may take place in the outer half of the CRZ but more after care is required. Tree health will be impacted. Loss of more than 50% of the root crown often results in tree mortality. Depending on the size of the roots severed, tree stability may be affected. The trees are located in the corner of the planter. There is not enough room for normal root plate expansion. Root pruning in areas to allow the original planter bed to be re-installed will affect tree anchorage as it will have to occur within the ICRZ. Conclusions: 1) Both the Critical Root Zone and the Interior Critical Root zone lies outside the dimensions of the courtyard itself. 2) The trees are located in the corner of the planter. There is not enough room for normal root plate expansion. 3) Root pruning in areas to allow the original planter bed to be re-installed will affect tree anchorage as it will have to occur within the ICRZ. Prepared by Doug Anderson for Bradley Burgoyne 5-15-14 Page 2 _ 4) Root growth is ma) ;the footing dangerous for the elderly �idents. There is no way to engage in root prun`t��g to allow for concrete replacement without effecting tree anchorage. The amount of the roots to be lost will have an adverse effect on tree health. Recommendations: 1) There is no room to safely root prune these trees to make the area safe for the residents. 2) Remove these trees and replace them elsewhere on the property.
