Cupertino, CA 95014-3255 � � RE: COAST LIVE OAK TREE#37 Crossroads Shopping Center, 20730 Stevens Creek Boulevard, Cupertino Dear Mr. Schroeder: As requested, I recently examined the large coast live oak #37 located at the above- referenced site (site visit performed on 6/26/12), and this letter provides a brief, preliminary summary of my observations, conclusions and recommendations. OBSERVATIONS The oak has a measured trunk diameter of 80 inches, and its age far predates development of the subject site. My initial observations of this tree in March 2011 revealed it to be viable and producing healthy foliage, but also that is has extensive decay around and within the lower trunk, visible buttress roots, and along major limbs throughout the canopy. It also has a massive cavity (hollow) filled with concrete at the lower trunk. The extent of decay present led me to initially conclude that the tree's structural integrity is significantly debilitated or impaired, and further investigation is needed. Recent root collar excavation work (performed on 6/20/12) fully exposed the top and bottoms of most all buttress roots, and revealed an increased extent of decay throughout the trunk's base and beneath some buttress roots. It also provides a fairly reliable indication (what is externally visible) that an advanced level of decay has decomposed the vast majority of the internal trunk area, and resulted in a significant loss in wood strength. p.o. box 25295, san mateo, california 94402 ■ email: arborresources@comcast.net phone: 650.654.335 I ■ fax: 650.240.0777 ■ licensed contractor #796763 ARBOR RESOLIRCES professional consulting arborists and tree care June 28, 2012 Crossroad Shopping Center page 2 of 3 I was also able to identify that there are numerous buttress roots mostly absent of decay and growing sound wood along the top sides, the presence of which serves to enable the tree to continue growing, showing signs of viability, and remaining upright (i.e. serving to anchor the tree to ground). I did observe decay along the top of one buttress root. Despite the extensive decay and rot, the sound growth of buttress roots essentially replaces some of the buttress root support, and appears to have effectively done so when considering the trees many additional years of life. Based on the extent of visible decay, I suspect an advanced level of decay was present long before the site was initially developed. As such, the new and ongoing buttress root growth would have been occurring approximately at or before this timeframe. Based on the tree's canopy extension and weight, targets currently within striking distance include contractor personnel, contractor trailer, parking lot (mostly or entirely the rear lot), and any persons within the planter area. The tree has a long history of major limbs breaking from the tree, as evidenced by the many tears and breaks seen throughout the canopy. CONCLUSIONS AND RECOMMENDATIONS Based on my evaluation, I conclude the following: ■ Decomposition of sound wood exceeds and accelerates the level of new wood production. ■ Given the extent of decay, a continuing, progressive and irreversible decline in the structural integrity is imminent. ■ The tree presents a potential, omnipresent danger of falling. • There are major defects along the majority of limbs throughout the canopy, defects that warrant significant reduction in the canopy to effectively reduce the potential for one to break and fall. p.o. box 25295, san mateo, california 94402 ■ email: arborresources@comcast.net phone: 650.654.335 I ■ fax: 650.240.0777 ■ licensed contractor #796763 ARBOR RESOLIRCES professional consulting arborists and tree care June 28, 2012 Crossroad Shopping Center page 3 of 3 � The tree is beyond repair, and there are no reasonable measures that can be employed to create a safe condition beneath or around it without debilitating its health and impairing its natural form. ■ Significant pruning, to potentially severe levels, is needed omit section of the tree within striking distance of frequently occupied (now and in the future) locations by persons and vehicles. ■ Severe pruning to achieve effective canopy reduction would only remove the majority of remaining foliage, weaken the tree's health, and hasten or exacerbate decline and potential demise. ■ Removal is the most appropriate management approach, conforms to the Town Code, and I recommend it occur as soon as possible. Any immediate concern could be addressed through additional pruning, and restricting access in areas within striking distance of the tree. ■ For mitigation, replacement with a larger specimen appears appropriate given the tree's very large size and long history. I suggest a valley oak (Quercus lobata) with a minimum 72-inch box size, and that the particular oak is evaluated and tagged by me at the nursery before being shipped to the site. I will follow-up with a more extensive report, including photos, in the upcoming weeks. In the meantime, please do not hesitate to contact me with questions. Thank you. Sincerely, I1� G � � David L.

Redwood City, CA. 94063 ``�"���� _�� �� ` � Project: Cupertino Crossroads Pad F Tree#37: Quercus agrifolia—Coast Live Oak The purpose of this report is to assess the health of Oak tree#37 after the work recommended in the tree report dated July 22, 2011 prepared by David L. Babby-consulting arborist. The existing river cobbles stones and pervious pavers were manually removed, dead branches in excess of 1"were removed and limbs pruned to reduce heavy limb weight,the existing support cables were inspected and deemed reliable at this time and did not require adjustment. On June 20th 2012, a root collar excavation was performed using an air spade and hand tools to expose the top and bottom of the scaffold roots approximately 16-24" from the trunk's base,which has revealed three large open cavities with areas of rot that appear to compromise much of the structural strength of the tree. David Babby was called immediately and informed of the findings,we have requested that he personally inspect the exposed roots and verify our findings. Construction activities around the vicinity of this tree continue, and grading/excavation tasks have been performed with no exposed roots. The tree does not appear to be impacted by surrounding construction, however due to the health condition of this tree,we recommend its removal.

Babby, Registered Consulting Arborist� July 30, 2012 1.0 INTRODUCTION The City of Cupertino Community Development Department has retained me to review the proposed removal of one coast live oak (Quercus agrifolia, assigned and tagged #37) located at Crossroads Shopping Center, 20730 Stevens Creek Boulevard, Cupertino. Specific tasks performed are as follows: ■ Examine the tree on 6/26/12 to [1] identify the extent of decay, or lack thereof, revealed following a root collar excavation performed by others on 6/20/12; [2] verify whether the excavation exposed sufficient trunk and root area to assess the extent of decay, and if not, determine whether an internal detection device was needed to acquire that information; and [3] present measures to mitigate any risk or hazard to less-than-significant levels. ■ Review observations and recommendations presented in my reports dated 4/4/11 and 7/22/11, as well as a summary letter dated 6/28/12. ■ Review a letter (not dated) by Kahn Design Associates, emailed to me on 6/25/12, requesting the oak be further evaluated. ■ Review a letter by Medallion Landscape Management, dated 6/22/12, recommending removal of the oak. ■ Provide findings as to whether the tree's removal conforms to City Code, and if it does, recommend a replacement tree to mitigate removal. ■ Prepare this report presenting my observations, conclusions and recommendations, and email it as a PDF document. 2.0 BACKGROUND I initially observed this tree in March 2011, and at that time, found it to be viable and producing healthy foliage, but also to have extensive decay within the lower trunk, visible buttress roots (large roots forming expanded growth at the trunk's base and serving as anchors for the trunk), and major limbs throughout the canopy. I also noted that it has a Oak#37, Crossroads Shopping Center, Cupertino Page 1 of 7 City of Cupertino Community Development Department David L. Babby, Registered Cortsulting Arborist� July 30, 2012 massive cavity (hollow) filled with concrete along the lower trunk, and many large tears and breaks throughout the canopy, an indication of a long history of major limbs breaking from the tree (and pruning of the tree likely non-existent for much of its life). The extent of decay observed led me to conclude that the tree's structural integrity is significantly debilitated or impaired, and as a result, I rated it to be in overall poor condition and to have a low suitability for preservation. In response, I recommended (in both reports) that further examination be performed, and measures for reducing the tree's risk of potential of failure employed. Those measures, as outlined in my 7/22/11 report, were recently performed, with the root collar excavation work completed on 6/20/12. A photo showing the entire tree (facing southwest) is presented below, and a map showing its location is presented on the following page. � , � s ���� ��",��:�. �«��� � � ���� � �� +��.k . ,, �; a��„ � a��,, °��. � � ���°�" � '���°�� ��`� � �� ��;�'��`���R�1v��'�� , �`�r�'"�� � � , �' '��.�'� � ,�ty'','. � ...1,� g� �"'b-'A ��,�' i:rr -.T"'*' 3 � -. £qyp� ..r ..•i�r.��y.,�,�,�'. ��,''J-� .,��� �,} �r.- ��� �� $- t� , i 4y '._'� +9' -� / W ��r" `t, �d� .. .

Based on its species and size, it is regulated as a "protected tree" pursuant to Section 14.18.035(B) of the City Code. During my site visit on 6/26/12, I found the root collar excavation work fully exposed the top and bottoms of most all buttress roots (these are massive roots serving to anchor the tree into the ground), and revealed a sufficient segment of the trunk and major roots to allow for a detailed assessment of decay. My examination ascertained extreme and advanced levels of decay throughout the trunk's base and beneath buttress roots, decay that has deteriorated or rotted the vast majority of internal trunk area, and significantly decreased wood strength. A description of my observations at various locations around the trunk are as follows, and photographs illustrating my observations are presented in Exhibit A: ■ Southeast side: There is a major buttress root that appears sound (i.e. free of decay) and forming new wood around its top; however, decay beneath is extensive. The is Oak#37, Crossroads Shopping Center, Cupertino Page 3 of 7 City of Cupertino Community Development Department David L. Babby, Registered Consulting Arborist� July 30, 2012 also a massive hollow filled with concrete, a likely result of a large 21-inch (approximately) limb failing many years ago. ■ East side: There is a hollow with extensive decay observed near the base, and the decay extends inward beneath major buttress roots. ■ Northeast side: There is a major buttress root with extensive decay at its bottom, and some is developing at its top. ■ North side: There is a four-foot tall and equally wide wall of deteriorating, decayed wood, extending towards the SW. Looking NW, there is also extensive decay. ■ Northwest side: There is a major buttress root, the top of which appears sound. ■ West side: There is extensive decay visible in all directions. ■ South side: There is some decay within one buttress root, and an adjacent buttress root that remains buried appears sound. My examination also revealed that all but one buttress root have sound wood growing around their tops and sides, a condition that explains, despite the extensive decay discovered, why the tree has for many years� remained anchored into the ground, continues growing, and exhibits signs of viability. If this were not the case, the tree would have likely uprooted and fallen over many years ago. Regarding the canopy (versus the lower trunk and roots), its structure is formed by five major leaders originating between four and eleven feet above grade along the main trunk. Along most all, decaying wounds are prevalent, and areas where this was observed are as follows: ■ The northern leader divides at approximately 15 feet high, and limbs beyond have extensive decay, large wounds from past limb failure, and dieback. ■ The western leader, the largest of them all, has three multiple locations where large limbs have failed and resulted in substantial decay. ■ The other three leaders are predominantly along the east side of the canopy, and have numerous, decaying wounds resulting from past limb failure. ' Based on the extent of decay found, I suspect decay was present long before the site was initially developed, likely by many decades or more than 100 years. Oak#37, Crossroads Shopping Center, Cupertino Page 4 of 7 City of Cupertino Community Development Department David L. Babby, Registered Consulting Arborist� July 30, 2012 4.0 DISCUSSION A tree's ability to produce sound wood more rapidly than decay decomposes wood serves as a potential threshold for determining whether a tree will continue thriving and remain viable, or whether it will progressively decline and become increasingly prone to demise and/or structurally failing (in whole or part). For this tree, decay comprises the vast majority of its internal trunk area and locations along most major limbs, and at rates far exceeding the tree's ability to produce new wood. As such, the risk of the tree to potential fail in part(e.g. a major limb failure) or whole (e.g. the tree uproots) is significant, a risk that is irreversible and will progressively increase overtime. The hazard associated with this risk involves failure onto frequent or constantly used targets (current and future), such as other persons, construction trailer, parking lot (mostly or entirely the rear lot) and vehicles. Options for potentially mitigating the risk or hazard to less-than-significant levels are as follows: a. Remove the tree. b. Severely prune the tree to omit sections within striking distance of existing and future targets; however, to effectively reduce the canopy, the majority of remaining foliage would require removal, thus debilitating the tree's health, degrading its aesthetic contribution, and hastening or exacerbating decline and potential demise. c. Restrict targets from accessing areas within striking distance of the tree (limbs and trunk); by doing so, the hazard effectively becomes eliminated or reduced. To achieve this, however, significant design revisions or site modifications would seemingly be necessary, parking spaces and drive accessibility reduced, the area fenced off, and the economic enjoyment of the property may be restricted by severely limiting the use of property in a manner not typically experienced by owners of similarly zoned and situated property. Oak#37, Crossroads Shopping Center, Cupertino Page 5 of 7 City of Cupertino Community Development Department David L. Babby, Registered Consulting Arborist� July 30, 2012 5.0 CONCLUSIONS AND RECOMMENDATIONS Based on my observations and review of potential mitigation measures, I conclude and recommend the following: a. The tree is beyond repair, and there are no reasonable measures that can be employed to create a safe condition beneath or around it without impairing its health and natural form. b. Removal is the appropriate management approach to effectively mitigate the risk or hazard. c. Removal should be permitted in accordance with finding number 12 and possibly 23 of Section 14.18.180 of the City Code. d. To mitigate removal, the subject oak's massive size and long history should be considered, and in doing so, replacement with a larger specimen appears appropriate. I recommend a valley oak (Quercus lobata) of a minimum 72-inch box size, and that the particular oak is evaluated and tagged by me at the nursery before being shipped to the site. Its location and method of irrigation should also be reviewed and approved by the City prior to installation, and if necessary, root pruning performed prior to or during installation. e. All new trees should be installed, including necessary irrigation, by an experienced state-licensed landscape contractor or a professional tree-service company, and performed to professional industry standards. Z Finding number 1 is as follows: That the tree is irreversibly diseased, is in danger of falling, can cause potential damage to existing or proposed essential structures, or interferes with private on-site utility services and cannot be controlled or remedied through reasonable relocation or modification of the structure or utility services. 3 Finding number 2 is as follows: That the tree's location restricts the economic enjoyment of the property by severely limiting the use of property in a manner not typically experienced by owners of similarly zoned and situated property, and that the applicant has demonstrated to the satisfaction of the approval authority that there are no reasonable alternatives to preserve the tree.
