Cupertino, California 95014 - �" " ~ "� �� �� Re: Four(4)Tree Removals at 20650 Valley Green Drive, Cupertino, CA Dear Mr. Vuong, This letter intends to address four (4) trees located at 20650 Valley Green Drive in Cupertino, California. The trees are growing along the north-side of the building in a landscaped planting area. This letter describes the trees and their conditions, in addition to recommending their removal (see Figure 1). Three (3) of the four individuals are Acer palmatum, Japanese Maples, and one (1) is Ulmus parviflora, Chinese Elm (see Figures 3 and 4). Their descriptions are as follows: • The Elm has codominant leaders that are ten (10) inches and thirteen (13) inches diameter at four and a half(4.5)feet above grade (DBH). It has a height of thirty-five (35) feet and a canopy width of twenty(20)feet. It is in good health with moderate structure. • Maple #1 has multiple stems that are six (6) inches, nine (9) inches, and six (6) inches DBH. It has a height of twenty (20) feet and a canopy width of twenty (20) feet. It is in moderate health with poor structure. • Maple #2 has codominant leaders that are both six (6) inches DBH. It has a height of twenty-five (25)feet and a canopy width of fifteen (15)feet. It is in moderate health with poor structure and overcrowded. • Maple #3 is approximately six (6) inches DBH. It has a height of fifteen (15) feet and a canopy width of ten (10) feet. It is in moderate health with poor structure and overcrowded. The trees listed above are recommended for removal. Specifically, the subject trees have invasive root systems and their removal will mitigate the roots' potential to cause damage to the adjacent structure (see Figures 5 and 6). The trees are too close to the structure. With compacted onsite soil conditions, large roots to grow very near the soil surface and, as a result, lift said structure. 2337 AMERICAN AVE,NAYWARD,CA 94545 OFFicE: (888)969-8733 80 GLENN WAY, UNIT#$SAN CARLOS,CA 94070 MAw FAx: (510)881-5208 3207 FITZGERALD ROAD, RANCH�CORDOVA,GA 95742 HR FAx(510)670-0275 5EO1 ERSTGATE DRIVE,SAN DIEGO,CA 92121 WWW.ARBQRWEL�.COM ►, Arbo'r ell. January 25t�, 2013 �>r«Fk ,::r,�; ,,,<,.�,.�a<,;,,t,,,� The trees listed above are considered protected trees pursuant to Section 14.18.035 of the City of Cupertino's Municipal Code and require a permit from the City's Planning Department prior to their removal. To mitigate the removals, we propose to replace with ten (10) 24-inch box Acer palmatum 'Sango Kaku', a varietal that exhibits a tighter vase branching structure and is known for its less invasive roots (see Figure 7). Five (5) are proposed to be planted on either side of the entrance, evenly spaced between the windows and centered between the building edge and curb, providing more clearance from the building than the existing trees (see Figure 3). In addition to the replanting material, a soil renovation will be performed, including rototilling all soil to a depth of eighteen (18) inches and soil amendments, encouraging deeper rooting and less potential for infrastructure damage. Please review this information and contact me with any questions or concerns regarding the information provided in this letter.

We reviewed Apple's "Tree Management Plan", which I consider to be very thorough and long range. The plan includes a thorough soil and inigation renovation at each location, which is planned for the two sites at: 10201 N. DeAnza Blvd. and 20650 Valley Green Drive. In my opinion, their plan for these renovations is much more long term than typical of most sites. This changes my opinion of these two sites. My impression of the Arborist Reports by Mr. Sam Oakley, Arborwell, was that they were only planning to remove the poor trees and replace with similar trees, which I considered to be a temporary solution. I envisioned the digging of small holes for the replacement trees, which is all too common by landscape companies. Thus, I envisioned that they were planning to put a "Band Aide" on the problem, which did not consider a good solution. However, this "typical" approach is not what they are proposing to do. They are planning to tear up the entire planter bed in each area, thoroughly renovate the soil, provide improved drainage as needed, and to renovate or replace the irrigation system, designed for the long term health of the new trees. At most sites, including the existing irrigation at these 2 sites, were designed to be primarily for shrubs and ground cover, which is not particularly effective for trees. They are proposing to redesign the irrigation at these sites for the long term health of trees, which means it will have the capacity to be adjusted as the trees mature. The renovation includes thorough soil amendment and mulching. I have since spoken with Mr. Oakley and told him that this concept of a thorough and complete landscape site renovation was not made evident to me in his reports. I asked that he be more explicit and more thorough concerning his reports to assure that we understand their intentions. Mr. Oakley agreed. Concerning 20650 Va11ey Green, I now can recommend their plan for complete renovation, including the removal and replacement of the trees recommended in Oakley's original report. Concerning 10201 N. DeAnza, I learned during my meeting with Paul Cebrowski that the neighboring property to the south (a Hotel) had recently done renovations to their landscape. In doing so, they had completely severed all of the buttress roots of all of the Red Ironbaxk (Eucalyptus sideroxylon) on the neighbor's side of the property. This potentially exposes all of these Red Ironbark trees on this property to failure. Because of this, I now recommend that all of the Red Ironbark trees be Removed and Replaced. I suggested to Mr. Cebrowscki to submit suggestions for replacements if they wanted any species that were not included in my report of the site. Is this sufficient or do you need revised reports for those 2 sites? Mick i Michael L.
