No soil was removed for below-grade inspection. This report contains the following: Introduction, Survey, Onsite Conditions, Problems, Past Trouble At Apple, Replacement Strategy, Appendix 1 (Tree Disposition Table) and Appendix 2 (Removals Map &Architect's Rendering) TREE SURVEY Data collected per individual tree for the inventory are as follows: tree tag #, common name, scientific name, diameter at breast height 4.5' above grade (inches) or just under multi branch crotch split, approximate height (feet), approximate canopy spread (feet), health and structural condition rating, action recommended, and comments. In addition to the collected observational data, the locations of the trees were plotted on a map using high-precision GPS technology. The site was visited on November 12th, 2012. Of the data collected in the field, health and structural condition (0 - 5; 0 = extremely poor, 5 = excellent) were observed. The health and structural condition of a tree is determined by the extent and size of foliage, the appearance of any abnormalities, and the overall health of the trunk and crown, in addition to the specific individual's general appearance relative to the ideal specimen of the species. Health and structural condition are subjective and species-dependent. ONSITE CONDITIONS Soil conditions on the property were observed. The soil moisture throughout the surveyed landscape was noticeably moderate. Observations suggest that the landscape is well irrigated and soil moisture conditions are good. PROBLEMS The 17 Plums at the 1 Infinite Loop entrance were planted over 20 years ago, are nearing their end of lifespan now, are water-needy, and of greatest concern, many have upheaved/uprooted rootballs (visible at the soil surface) in combination with leaning trunks (visible from a distance) evidence of compromised structural integrity of the trees, some to a potentially dangerous degree (see Figure 2 & 3) Some of these hazardous trees are also within target range of passing and sitting pedestrians below them which only increases the liability to Apple. The Plum trees are quite inconsistent in their size, shape, and health condition, overall are quite thin in terms of canopy density, have poor branching structure, are quite crowded in their planters, and the majority of foliage is produced by suckering shoots as opposed to true branch laterals, which is less than desirable (see Figure 4) Advanced decay and decline is also appearing, evidenced by tip dieback and cambium loss (see Figure 5 & 6) The value of replacing these Plums at this time with a superior species appears to exceedingly outweigh their preservation. The condition of each of the Plum trees can be reviewed in the tree disposition table below (see Appendix 1) � Apple Confidential—Do Not Distribute Date of Report: November 16, 2012 2 •�� . -� > :1� y�,.y ''►�3� ."'. . . `�P"'pj.v. 0. r � � i . . � �'� ��'` '�'�+ ' , � ir `}f�,:i� ,`�•�. _�i�� .� '���y,y�,.�q.��. � �,r� s ,y �`. . .sr �`C �r��r. i 1. , a _ "wi`°-�� ew�,ir:'.rj'�?

PAST TROUBLE AT APPLE Multiple Plum trees have apparently fallen over in these planters over the years, fortunately not landing on anyone in the process. However, the potential threat for recurring failure continually looms, within dangerous proximity to the ever-present target of high pedestrian traffic flow daily between these planters. These fruiting Plums have also proven notorious for fruit drop and creating an enormous mess and maintenance nightmare over the main entrance hardscape, even despite bi-annual attempts to inhibit fruit production. ��� Apple Confidential—Do Not Distribute Date of Report: November 16, 2012 5 � � � �.'�," � �� �,,.,,.._. � ._, '`\� � �,�� ;� w "" � '� � ,��' �`� � '� ���.�'� ��" f. ��'��� �� .•�, w:� �w �� .:� �.�T � � ���' . �� �� �> , .. . .,�,,��.r �,.

These inconsistent, end of lifespan, dangerous and declining Plum trees should soon be removed and replaced with a superior tree species. REPLACEMENT STRATEGY It is recommended that the Plums be removed and replaced with a superior tree species that possesses the following desirable qualities; long-lived, hardy, structurally strong, drought-tolerant, evergreen, pest-resistant, non-fruit bearing and Mediterranean climate adapted. We are proposing to replace these seventeen (17) Purple-leaf plums, Prunus cerasifera, with six (6) 60-inch boxfruitless Olives, O/ea europaea 'Swan Hill' (see Figure 8) which we feel successfully meet the criteria/qualities listed above. Per City of Cupertino Protected Tree Ordinance, removal trees 12" DBH or less require one (1) 24" box replacement tree. Our proposition is to replace the Plums with vastly superior trees (Olives) that exceed the standard mitigation box size of 24" by 3 full box sizes (60") We feel that each of the proposed 60" box Olives present a mitigation value that could reasonably be considered equivalent to every 3 inferior Plums we are proposing to remove and replace, when comparing the polarizing qualities of the Plums to the Olives, and the much larger replacement tree box sizes proposed for the Olives. Planting 3—60" Olives for each of the raised planter beds down the center will also provide more space and less competition for the � Apple Confidential—Do Not Distribute Date of Report: November 16, 2012 6 Olive trees to establish stronger and more consistently, while providing sufficient space to showcase their spectacular structure. Please see Appendix 2 for aerial view of proposed re-planting locations along with an architect's rendering of the proposed design and layout. The Olives are not only immensely longer-living, hardier, structurally stronger, exceedingly more drought- tolerant, and a vastly superior Mediterranean climate adapted species than the existing Plums, but the Olives also possess the attractive qualities of being evergreen, and non-fruiting, also promoting pesticide reduction. � . ���Y��U �1:4 n,,� , �° �'.

Vuon � g Community Development Department �EC j 1 ZQ�Z City of Cupertino 10300 Torre Avenue �' Cupertino, CA 95014 � RE: PROPOSED REMOVAL OF 17 PURPLE-LEAF PLUMS 1 Infinite Loop,Apple Campus, Cupertino Dear Mr. Vuong: You have asked me to review the proposed removal of 17 purple-leaf plum trees (Prunus cerasifera) from the above-referenced site. Specific tasks performed are as follows: ■ Review the applicant's report, dated 11/16/12. ■ Visit the site on 12/6/12, and identify the 17 trees proposed for removal. ■ Ascertain each tree's health and structural condition. ■ Confirm the trees' approximate locations and trunk diameters. ■ For location purposes, utilize the map showing tag numbers; it was emailed to me on 12/3/12, and I have attached it to this report. ■ Utilize tree numbers provided in the applicant's report, as well as shown on the racetrack-shaped tags affixed to the trees' trunks. ■ Specify whether any of the trees are regarded as "protected trees"per City Code. ■ Obtain photographs to catalog each tree (see attachment). ■ Present findings as to whether the proposed removals conform to City Code. ■ Review the species, size, amount and location of trees proposed for installation. ■ Prepare this letter report containing the above information ,�--y�,, ��^� r^;.(.. .,.,.._,...,,�..�!���._.��''/,,Z��..S�� f�; � _ ..;f }� .��j ��l���y! , . . -..�.�_,._. � � _ _ ._ _..._. 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 December 11, 2012 1 Infinite Loop page 2 of 4 OBSERVATIONS The 17 subject plum trees are assigned and tagged as #238 thru 254, and align both sides of the walkway leading to the building's lobby entrance. They are of relatively equal size with trunk diameters ranging between eight and ten inches, heights of 15 to over 20 feet, and canopy spreads of around 10 to 20 feet across. Photographs of the trees, by assigned number, are assembled on the attached sheets. Based on the site, it is assumed that the trees were planted or retained as part of a previously approved and planned development. As such, they can be considered regulated and defined as"protected trees"pursuant to Section 14.18.035(C) of the City Code. My assessment of their condition reveals that they are in overall poor to very poor condition, and beyond recoverable status. Large deadwood, highly excessive pruning over the years, weak structural integrity, and possibly fruit control applications all contribute to their weakened condition. Several of the trees' actual locations, as shown on the attached map, vary slightly from what is shown on the supplied map attached to this report (and more so on the map presented as Appendix 2 in the applicant's report). On the attached map, from their plotted locations, #243 and 244 are roughly ten plus feet west, and#246 thru 250 are about ten feet east. p.o. box 25295, san mateo, california 94402 ■ email: arborresources@comcast.net phone: 650.654.3351 ■ fax: 650.240.0777 ■ licensed contractor #796763 ARBOR RESOLIRCES professional consulting arborists and tree care December 11, 2012 1 Infinite Loop page 3 of 4 CONCLUSIONS AND RECOMMENDATIONS Upon consideration of my observations, it is my opinion that the plum trees' continued decline and structural degradation will occur during their remaining lifespan, and their useful and functional life have reduced significantly. As such, I find that the removal of all 17 conforms to fmding one of Section 14.18.180 of the City Code. Their removal and replacement with a more suitable species will greatly benefit and promote a more prominent future tree landscape, while enhancing and complementing the architectural building features. Applying Table A, Section 14.18.185 of the City Code, mitigation for their removal would involve the installation of 17 trees of 24-inch box size. The applicant is requesting to alternatively install six olive trees of 60-inch box size (fruitless variety named Olea e. 'Swan Hill'), three along each side of the building. Their proposal does not identify replacements within the individual planters nearest the drive aisle (the ones that contain existing trees#238 thru 240 and 252 thru 254). Based on my assessment of the proposed planting areas, I find that installation of six multistem olives of 60-inch box size (three per side) are an excellent selection as they will instantly provide recognizable stature and promote a superior future landscape; the 60-inch boxes are approximately 12-14' tall and 10-11' wide, and the 24-inch boxes are only 5-6' tall and 4-5' wide. I recommend they are evenly spaced within the planters. Additional landscape (ground cover, shrubs, etc.) should also be identified as there will be a sizeable, exposed ground area following installation. p.o. box 25295, san mateo, cal�fornia 94402 ■ ema�l: arborresources@comcast.net phone: 650.654.3351 ■ fax: 650.240.0777 ■ licensed contractor #796763 ARBOR RESOLIRCES professional consulting arborists and tree care December 11, 2012 1 Infinite Loop page 4 of 4 For the stand alone planters nearest the drive aisle, I am unclear as to the future landscape. I suggest that short, ornamental trees are considered there,perhaps one or more per planter, and be low-growing to not impede the aesthetic value provided by the olives. Examples include Acer palmatum 'Dissectum Ever Red' and Prunus serrulata 'Weeping Double Pink'. The installed size should be 24-inch box. This concludes my letter, and please do not hesitate to contact me with any questions or if I can provide further assistance. Sincerely, �/� G • �i�-il David L.
