See section available of 5.0 of this report below. the date of writing. 2.0 Assignment & Background Walter Levison, Consulting Arborist (WLCA) was initially retained by Vallco Property Owner LLC (VPO) to tag and assess 895 trees throughout the existing site that extends from perimeter road west to perimeter road east, and from freeway 280 to Stevens Creek Boulevard, Cupertino, California, including median trees along North Wolfe adjacent to the Vallco site. The east boundary of the survey area was a property owned by Apple Inc. The west boundary of the survey area was a developed single family residential area. Tags in this area are tagged #1 through #875 (round -shaped tags), with median trees tagged as #1,106 through #1,125 (racetrack -shaped tags) along N. Wolfe Road. WLCA's initial work product consisted of an Excel tree data set in PDF format, along with digitally marked up tree location maps, delivered to VPO in spring, 2015. The initial proposed development set of plans for The Hills at Vallco had not yet been developed at that time, and was not available for review. A secondary tree study was also completed by WLCA, which involved tagging, assessing, and locating on a topo sheet all trees located north of the Vallco site in a triangular lot known as `alternate lot west', situated between the northwest corner of the Vallco shopping center property and freeway 280. Trees in this area were tagged as trees #876 through #1,105, with round - shaped tags to #1,000, and racetrack -shaped tags for trees numbering greater than 1,000. N. Wolfe Road median trees #1,106 through #1,125 were added at this time, using the racetrack - shaped tags as noted above. WLCA was later retained in September 2015 to prepare a formal written arborist report that was to include the following items: a) Review the DropBox set of proposed plan sheets as available in September 2015. If possible, note conflicts where initial proposed utilities and construction may impact trees being retained, and discuss adjustments to the plans as applicable. 8 of 48 Site Address: Vallco Shopping Center, Cupertino, CA Version: 10/30/2015 © Walter Levison 2015 All Rights Reserved Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture Cell (415) 203-0990 / Email drtree(a),sbcalobal.net Walter Levison��. CONSULTING ARBORIST `� ASCA Registered Consulting Arborist #401 ISA Qualified Tree Risk Assessor ISA Certified Arborist #WC-3172 b) Update the existing Excel tree data spreadsheet to note an "X" in removal column indicating tree to be removed. c) Discussion of trees to be retained and trees to be removed, including species overviews, condition ratings, etc. d) Note trees protected per Cupertino City Tree Ordinance being retained and removed. e) Note trees suggested by WLCA to be removed due to very poor condition. f) Note possible adjustments to the scope of construction to optimize tree survival and/or preserve important trees on the site as applicable (see also item `a' above). g) Note irrigation and soil moisture deficit concerns and options. h) Note tree part failure risk concerns. i) Archive digital images of some important or otherwise noteworthy tree specimens and include those images in the report. j) Attach the updated Excel tree data charts and a master tree location basemap to the report. k) Prepare recommendations for transplanting on-site for significant sized trees that are expected to be removed as a result of site plan work, with new install locations to be noted by Consultant on the proposed site plan drawings. Specifications for holding trees in boxes, etc. (i.e. "box holding" recommendations for irrigation, maintenance, etc.). 1) Recommendations for tree protection and maintenance based on arboriculture BMPs, with phased protection and maintenance conforming to the current proposed demolition and construction phases 1, 2, and 3. All of the above items are included in this written report. Most of the information has been presented in matrix form, for ease of reference. The updated WLCA tree data sheets (Excel format) are attached to this report. Olin Studio's single PDF landscape plan sheet P0601 "existing tree conditions", based off WLCA's original Spring 2015 rough -plot tree location maps, is attached to this report for reference of existing tree locations. 3.0 Observations & Discussion Existing trees at the Vallco site (not including alternate lot west): 3.1 Predominant Tree Species at Vallco Tree Species Number of individuals Percent of total tree population of 895 Shamel ash 399 45% (Fraxinus uhdei) Coast redwood 319 36% (Sequoia sempervirens) Pine species (mainly Pinus radiata and 65 (approx.) 7% Pinus pinea) As seen above, the tree population percentages of coast redwood and shamel ash along the Vallco property perimeter are far too high for a stable urban forest situation. In an ideal world, we would stratify the population out using a large number of tree genera and species to guard against pest and disease outbreaks (and abiotic issues such as drought conditions) that could potentially wipe out a large percentage of the tree population. 9 of 48 Site Address: Vallco Shopping Center, Cupertino, CA Version: 10/30/2015 © Walter Levison 2015 All Rights Reserved Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture Cell (415) 203-0990 / Email drtree(a),sbcalobal.net Walter Levison CONSULTING ARBORIST ASCA Registered Consulting Arborist #401 ISA Qualified Tree Risk Assessor ISA Certified Arborist #WC -3172 The existing monoculture type planting was from an earlier era when the Vallco site was originally built out and planted using mainly coast redwood and shamel ash. These trees are very heavy water users, and have been suffering for years during the continuing California drought conditions with subnormal rainfall. Supplemental very heavy irrigation on a regular basis throughout the year is crucial to keeping coast redwood and shamel ash alive and vigorous. However, the ash and redwood specimens at Vallco have not been receiving this level of irrigation, and are spiraling into decline and in many cases death. At this time, the property owner is not proposing any significant alterations to the perimeter tree populations on Vallco property, and the screening benefit of the perimeter trees will remain as long as individual trees are alive and thriving. Note also that many of these trees are not actually on Vallco property and are within a public utility right of way (personal communication, Vallco property owner 10/23/2015). 3.2 Tree Condition Study Overall Tree Condition Ratings for Two Main Species in Population (Not including alternative lot west) Tree Number of Dead Very Poor Fair Good Excellent Species individuals Poor Coast 319 15 52 74 110 66 2 redwood Percent of redwood (100%) 5% 16% 23% 34% 21% <1% population Tree Number of Dead Very Poor Fair Good Excellent Species individuals Poor Shamel 399 2 65 161 156 15 0 ash Percent of Shamel (100%) <1% 16% 40% 39% 4% 0% ash population Interestingly, the above study shows somewhat of a bell curve form, where most of the tree individuals rated out with overall condition ratings in the middle portion of the rating range (range is from dead (0%) to excellent (90% to 100%). If droughty conditions continue in California with subnormal natural rainfall this winter, many of these trees could continue spiraling into decline and end up with all ratings in the dead, very poor, and poor portion of the rating range, unless very heavy irrigation were to be commenced at this time and continued regularly through the entire winter. 10 of 48 Site Address: Vallco Shopping Center, Cupertino, CA Version: 10/30/2015 © Walter Levison 2015 All Rights Reserved Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture Cell (415) 203-0990 / Email drtree(a),sbcalobal.net Walter Levison &NA CONSULTING ARBORIST ASCA Registered Consulting Arborist #401 ISA Qualified Tree Risk Assessor ISA Certified Arborist #WC-3172 3.3 Drought Effects on Vallco Trees Given the current low soil moisture conditions that have been present in the San Francisco Bay Area for multiple years now, and continued subnormal natural rainfall conditions, the moisture available to the coast redwood and shamel ash tree root zones at Vallco is very minimal. This has resulted in chronic loss of live twig density and live foliar density in the trees, which is expressed visually as desiccated, dead patches of canopy seen in the trees, especially in the outermost, uppermost sections of the tree canopies of individual specimens along the east and west sides of the west perimeter road (see images below in this report). It is not clear whether tree vigor (new live twig and foliar growth) will be or can be boosted through either very heavy, sustained supplemental irrigation of the trees' root zones, or through natural rainfall finally occurring after the (existing) prolonged period of subnormal soil moisture. Generally, trees that decline to an overall condition rating of poor (i.e. less than 50%) will not increase in vigor until very heavy irrigation is applied over an extended period of 6, 12, or even 18 months' to the trees' entire root zone areas. Even after this type of serious irrigation regime commences and is continued for the extended period, the trees may still not respond favorably, and will continue to decline. High quality irrigation water with low ionic content needs to be available for supplemental irrigation of coast redwoods. See section 3.5 below for more information. 3.4 Soil Moisture Deficit / Moisture Requirements Shamel Ash and Coast Redwood Moisture Requirements In order to keep coast redwood and shamel ash specimens from declining in live twig density, live twig extension, and live foliar density over time, a very heavy irrigation regime will need to be set in place as an over - grade no -dig type system placed over the ground throughout the open soil root zones of individual trees and groupings of these trees being retained at Vallco. Although the actual volume of supplemental water to be applied per week per coast redwood specimen varies with soil conditions, weather, solar exposure, and other issues, the following is a set of rough guidelines for water application based on the author's experience. Note that use of a heavy mulch of coarse chipper truck type wood chips Iain over the I Levison, Walter.

The trees' root zone areas need to be allowed to "dry down" as water percolates through the uppermost few feet of the soil profile, and is then used by the trees (transpired) or evaporates into the atmosphere (evaporation from open soil). As noted above in this section, use of mulch is beneficial if a layer 4 inches thick can be placed over the open soil root zone areas of the trees, between approximately 1 foot out and 25 feet out from the trunks of the trees. Optionally, we could install some type of fogging system to augment moisture uptake by the trees by adding fog water to some lower canopy or mid canopy locations.

Thus, use of a fogging system could potentially be of great benefit to the trees, if such as system could be affixed to locations near canopies at varying elevations above grade. Above are images of aerial sprinkler or aerial misting systems that were in actual use on local peninsula Bay Area project redwood specimens (images courtesy of Ray Morneau, Consulting Arborist). The images shown in this report section show materials used to build a misting system, with the system activated and running in the last of the three images. These systems would require a substantial initial investment in piping, mistheads, and labor to install, but have been beneficial in terms of increasing tree survival during hot or windy periods, according to other arborists and nurserymen I spoke with in 2015. 3.5 Ion Content in Recycled Water / Standards Many municipalities such as San Jose and Palo Alto are using recycled water as a regular component of their City parks irrigation regime. However, this does come with known drawbacks. Coast redwoods are known to be sensitive to ion concentrations in soil water per the text referenced below3. The text notes that coast redwood has low tolerance of boron ion in recycled water. Ion sensitivity of coast redwood as related to other ions such as 2 Burgess SSO, Dawson TE (2004).

However, per the author's conversations with numerous city arborists and consulting arborists in the Bay Area, coast redwood appears to have low tolerance of specific ionic content in water in addition to boron ion. The following table derived from information in the below -referenced text provides some guidelines for total ion content of various ions in recycled water at levels that could be deemed "safe" for trees with low tolerance (high ion sensitivity), although this is only a guideline, and was published more than 10 years ago: Salinity tolerance of various tree species proposed in the Hills project tree palette by OLIN is noted in the reference shown in this report as citation #3. WLCA is in communication with OLIN staff to discuss salinity tolerance issues. EXISTING REDWOODS The new project does not proposed to use recycled water for irrigation of the existing redwoods being retained as perimeter screening (personal communication 10/23/2015, Mr. Steve Lynch, Sand Hill Property Co.). Therefore, the ionic content of irrigation water appears (at the time of writing) to be an issue with new proposed tree plantings only. 14 of 48 Site Address: Vallco Shopping Center, Cupertino, CA Version: 10/30/2015 © Walter Levison 2015 All Rights Reserved Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture Cell (415) 203-0990 / Email drtree(a),sbcalobal.net Unsafe for Tree Irrigation Water Ion Type of Content Range "Safe" Species with Low Measurement Considered Tolerance to Stated Ions TDS Total Dissolved Mg/I <450 450 to 2,000 Solids Salinity Mmhos/cm <0.7 0.7 to 3.0 Boron Mg/I <0.5 0.5 to 1.0 Chloride (surface bubbler Mg/I <140 140 to 300 irrigation) Chloride Mg/I <100 >100 (sprinkler irrigation) Sodium (surface bubbler SAR <3 3 to 9 irrigation) Sodium Mg/I <70 >70 (sprinkler irrigation) Salinity tolerance of various tree species proposed in the Hills project tree palette by OLIN is noted in the reference shown in this report as citation #3.

CONSULTING ARBORIST `� ASCA Registered Consulting Arborist #401 ISA Qualified Tree Risk Assessor ISA Certified Arborist #WC-3172 USE OF RECYCLED WATER BLEND AND FLUSHING SEQUENCES To reduce ion content in irrigation water to acceptable levels per the above matrix guidelines, recycled water with high ion content can be blended with standard municipal drinking water prior to running it through irrigation systems for surface application to trees. Per the Vallco property owner, this blending will be performed seasonally during non water -restriction periods in order to comply with local regulations regarding potable water use for landscapes during drought periods. Another "trick" that can be performed to reduce ionic content remaining in the root zones of trees is to use recycled water for a number of irrigation cycles (e.g. 4 to 9 cycles), then "flush" the root zones by using a 5th or 10th irrigation cycle of 100% municipal drinking water (anecdotal reference). This would require that a very detailed record of irrigation be maintained by a groundsperson on site, to record exactly when recycled water and drinking water was applied to very specific landscape zones. Both recycled water and drinking water would need to be available side by side as irrigation system inputs with manual levers that would be operated by the groundsperson. OAK TREES BEING INSTALLED Per discussions with Apple Inc.'s arborist Mr. Dave Muffly who is an expert in oak tree selection and cultivation, oak species being installed at The Hills should be provided with municipal drinking water as the irrigation water source, without any blending with recycled water. This is recommended to avoid potential problems with ion sensitivity by the oaks. Mr. Muffly notes that the Apple Campus 2 project will not use recycled water for irrigation of the oaks (AC2 campus is also within the jurisdiction of City of Cupertino, and has recycled water piping that will be used for irrigation of non -oak landscape zones). As regards The Hills roof planting area where many oak species will be installed at Vallco, we may need to develop a special dual piping system which will allow for recycled water and standard drinking water sources to be piped up separately. This would allow the two water sources to be applied in an alternating manner and/or blended in a tank prior to being applied to sensitive species such as the oaks and fruit bearing orchard trees, to reduce the overall ionic content being applied to the landscape over time. WEEPING WILLOW AND FREMONT COTTONWOOD AT ROOF DRAINAGE SWALES The Abiotic Disorders text (citation #3) noted above in this report contains a list of various tree species along with referenced scientific studies during which salinity and boron tolerance was determined for certain species. Per this list, Fremont cottonwood, proposed to be installed at The Hills in swales where runoff collection will occur, exhibit "moderate" to "high" tolerance of salinity (i.e. ionic concentrations) in recycled water, which would suggest that they can tolerate soil moisture derived from runoff water that may contain higher than normal ionic concentration. Weeping willow, also proposed by the project team for inclusion in drainage runoff swales at our site, also appears to exhibit "moderate" to "high" tolerance of ionic concentration in irrigation water, which also suggests tolerance to runoff water as the main source of their root zone soil moisture. Even so, WLCA suggests considering removal of these two species from the proposed plant palette list, given that they require heavy irrigation year round to maintain vigor. 15 of 48 Site Address: Vallco Shopping Center, Cupertino, CA Version: 10/30/2015 © Walter Levison 2015 All Rights Reserved Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture Cell (415) 203-0990 / Email drtree(a),sbcalobal.net Walter Levison��. CONSULTING ARBORIST `� ASCA Registered Consulting Arborist #401 ISA Qualified Tree Risk Assessor ISA Certified Arborist #WC-3172 RECYCLED WATER EFFECTS ON FRUIT -BEARING ORCHARD TREES Per the text referenced in citation #3 in this report, fruit -bearing tree species proposed by the team for the rooftop orchard which will be for human consumption are noted in the text as exhibiting "low" relative tolerance to ionic content in recycled water used for irrigation. Given that fruit bearing orchard trees generally require heavy irrigation, this is of concern if recycled water is going to be used on the Hills greenroof where the orchard areas will be located. As noted above in this section of the report, blending recycled water with municipal drinking water can bring down ionic concentration to levels below the safe thresholds noted above in the matrix. Flushing the tree root zones by use of 100% drinking water on a periodic basis may also be a viable method of reducing ionic concentration buildup in the root zones of the trees, such as the example WLCA noted of 4 to 9 irrigation cycles using recycled water, followed by a 5th or a 10th irrigation cycle using 100% municipal drinking water (anecdotal reference). Per the author's recent conversation with a Northern California soil scientist who specializes in orchard soils, the inability for fruit trees such as cherry, apricot and apple to tolerate ion content in recycled water used for irrigation appears to be verified. Blending and/or other dilution is warranted. Again, use of a dual piping system to bring up both standard drinking water and recycled water sources to the greenroof may be able to solve the problem of ionic content in recycled water being applied to the orchard areas, as it will allow us to blend the two sources of water and/or apply them to the landscape in an alternating manner to flush salts through the soil. WLCA suspects that over time, municipal recycled water may become of increasingly higher quality in terms of ionic content being reduced to below the low -tolerance sensitivity threshold of 0.7 Mmhos/cm salinity. Refer to the ionic content table on page 14 above for more information. 3.6 Effects of Proposed New Utilities Plan on Woody Roots The negative effect of proposed new utility trenching per project sheet P-0506 on existing trees to be retained could be significant to severe, depending on the actual final sprayed routes of these utility trenches. The current plan sheet shows utilities as conceptual routing only, and it is therefore difficult to determine actual impacts to specific trees. However, WLCA did note various groupings of trees and expected (potential) impacts to those trees from utility trenching, in the summary matrix section 1.0 lines #6 through #10 above in this report. Typical woody lateral root growth extends from trees at least 3X to 5X the canopy dripline radius per previously published arboriculture science texts. This growth is generally present between grade elevation (i.e. soil surface) and down to approximately 24 inches below grade in our western Bay Area urban clay -based soils, though in some cases, older redwoods and oaks can achieve large diameter woody root growth at depths as far as 50 to 60 inches below grade For tree stability maintenance, it is acceptable to sever roots at locations within 25 to 30 feet of large diameter coast redwoods and shamel ash. However, utility trenching within 25 feet of those trees may cause severe negative impacts to the trees' health and structural condition, resulting in premature decline and/or death. In those cases where utilities need to be routed within 25 feet of large trees being retained, WLCA suggests using pit to pit directional bore technology whereby conduit is pushed and pulled below the root systems of trees being retained, thereby allowing for ' Levison, Walter.

CONSULTING ARBORIST `� ASCA Registered Consulting Arborist #401 ISA Qualified Tree Risk Assessor ISA Certified Arborist #WC-3172 4.0 Risk of Failure / Tree Risk Assessment Qualified (TRAQ) Prior to the newer International Society of Arboriculture (ISA) TRAQ system (tree risk assessment qualified) coming into place as the new international standard for tree part and whole tree failure risk assessment, arborist consultants referred to an older numeric system of 12 points which consisted of: • Failure potential of identified part (1 to 4 points) • Size of part (1 to 4 points) • Target rating (1 to 4 points) The final numeric "hazard rating" derived from this system ranged from 3 to 12 points 5. The newer system is based on alpha -type ratings, and requires the tree risk assessor to attend a rigorous training class sponsored by the ISA, after which the assessor takes a final exam. Assessors that pass the final exam are then given the title "tree risk assessment qualified", after which time they are allowed to use the published system and its components6 and prepare information on tree risk in written reports. Qualified tree risk assessors must retake the qualification course and exam every few years to renew status as tree risk assessment qualified. The basic TRAQ process has been amalgamated into a matrix below (next page) for readers of this report. Note that TRAQ risk ratings are derived after consideration of various different failure modes (e.g. branch, scaffold limb, mainstem, whole tree) and different targets such as vehicles, pedestrians, bicyclists, residential structures, commercial buildings, etc. Target frequency and duration at a specific target zone, such as cars and pedestrians stopped at a traffic light, are considered when determining target "occupancy", in order to determine risk of tree part failure and impact of that tree or tree part onto that specific target at that moment when the target is occupying the target zone radius. 5 Matheny, Nelda and Clark, James. 1994.

This leaves a total of approximately 450 trees to remain on site, mainly coast redwoods and shamel ash, along the perimeters of the site that are vulnerable to proposed construction damages in terms of both subgrade impacts to roots from trenching, soil compaction, etc. and above -grade physical impacts to the trunk tissues and canopy live wood and foliage. Use of WLCA and/or other arborists as monitors will help minimize risk of tree damages that could increase risk of whole tree and tree part failure and impact to targets. Designing around trees to avoid deep excavation, trenching, grading, construction, and other work within 20 horizontal feet of trunk edges can go a long way toward reducing impacts to the trees being retained, and reducing risk of tree failure and impact to targets. Given the existing issue of soil moisture deficit (i.e. "drought stress") and lack of adequate irrigation to boost soil moisture within the root zones of trees being retained, WLCA expects that many of the trees to remain may actual become moderate risk or high risk specimens over time due to their premature decline in terms of loss of live twig density. As an example of our current risk exposure and future risk of tree failure and impact to targets as related to irrigation, WLCA offers the following sample risk assessment of a typical coast redwood along the west perimeter road: SAMPLE RISK ASSESSMENT FOR A TYPICAL VALLCO COAST REDWOOD TO REMAIN Typical coast Likelihood of Risk of redwood Condition Likelihood impacting Likelihood Failure and specimen / Location (Average of failure target of failure Consequences Impact Mode of Failure existing) pedestrians and impact (Existing) and cars #772 to #871 West side of Somewhat Failure Mode: west Fair Possible High Likely Significant Low Branch perimeter road Typical coast Likelihood Likelihood of Risk of redwood Condition of failure impacting Likelihood Failure and specimen / Location (Future (Future target of failure Consequences Impact Mode of Failure estimated) est.) pedestrians and impact (Future and cars est.)

These include trees such as, but not limited to: Trees #434, 435, 438, 726. 1109, 1110, 1111, 1112, and 1115. Many of these elevated -risk type trees are included in the group of trees suggested to be removed per WLCA in summary matrix 1.0 line 5, or are to be removed outright due to site plan conflicts. However, N. Wolfe Road median shamel ash specimen #1115, for example, is proposed to remain per the current proposed site plan tree disposition sheet. There may be many additional trees that become "elevated risk" specimens due to root loss, root damage, and continued soil moisture deficit, during the actual construction of phases 1, 2, and 3 at The Hills at Vallco project over time. Use of heavy irrigation at the site starting now (Fall 2015) may be very beneficial in the long run in terms of reducing dieback and lengthening expected useful lifespan of the trees by providing good soil moisture to trees being retained. 5.0 Landscape & Irrigation Pipe Installation Concerns Demolition of Existing Planters / Concerns: Demolition of existing curbs, planting areas, asphalt parking stall surface materials, etc. to make way for new landscaping may cause significant or severe damage to the below ground portions of trees being retained such as shamel ash at the southwest end of the site along the south boundary of the existing SEARS parking lot. The image capture at right shows a portion of project team sheet P-0609 main entry area landscaping proposed for this southwest corner area of The Hills project: Some of the trees such as those circles drawn along the hard black line property boundary that rings the site are shamel ash specimens being retained, while other trees drawn on this sheet by the landscape architect are proposed new "in -fill" trees to augment existing screening. r w 21 of 48 Site Address: Vallco Shopping Center, Cupertino, CA Version: 10/30/2015 © Walter Levison 2015 All Rights Reserved Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture Cell (415) 203-0990 / Email drtree(obsbcalobal.net Walter Levison Nc CONSULTING ARBORIST ASCA Registered Consulting Arborist #401 ISA Qualified Tree Risk Assessor ISA Certified Arborist #WC -3172 WLCA's main concern in areas such as this involves demolition crew activities during removal of surface hardscape and deep curbs, which may be comingled with existing woody tree root systems. When pulling out the curbs and hardscape piece by piece, these roots may become tangled with the machinery bucket teeth and be pulled, ripped, or otherwise destroyed or damaged in the process. Therefore, an arborist monitor is suggested during demolition of any material within approximately 20 feet of a tree to be retained. As noted above in this report, we know that woody tree roots can extend laterally as far as 3x to 5x the canopy dripline distance from the trunk edge, which means that a 20 foot radius canopy tree may theoretically have roots extending as far as 60 to 100 feet radius out from trunk, even under asphalt, if there are no physical impediments to growth extension such as deep curbs or deep foundation footings. Irrigation Pipe Trenching / Concerns: New irrigation pipe trenching will need to be performed in a manner that allows for maximum lateral woody root retention when within 20 horizontal feet of trees being retained such as those shown in the image above near Stevens Creek Blvd. Toward this end, we will need to modify the standard (typ.) municipal code 18 inch depth of cover spec detail used in most jurisdictions for schedule 40 PVC piping, and instead use one of the following options: Option 1: "No Dig". This irrigation type uses flexible'/2" diameter tubing that starts at a PVC riser at 20 feet or farther from a tree trunk of a tree being retained, and proceeds to snake over the ground to locations within 20 feet of a trunk of an existing tree where irrigation is needed. Bubblers are either affixed to the tubing itself, or to offshoot t/4" diameter tubing with bubblers. There is also emitter line that is available in'/2" diameter, with built in bubblers, though these tend to clog easily. The no -dig option is optimal in terms of protecting lateral tree roots extending out from existing trees. However, vandalism is always a problem. The tubing can be buried slightly by covering it with a 4 inch thick layer of wood chip mulch to avoid some vandalism, but further measures may need to be taken to keep the tubing flush with the soil surface, such as pinning down the tubing with professional grade steel landscape U -pins, etc. See image at right. 22 of 48 Site Address: Vallco Shopping Center, Cupertino, CA Version: 10/30/2015 © Walter Levison 2015 All Rights Reserved Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture Cell (415) 203-0990 / Email drtree(a),sbcalobal.net Walter Levison &NA CONSULTING ARBORIST ASCA Registered Consulting Arborist #401 ISA Qualified Tree Risk Assessor ISA Certified Arborist #WC -3172 Option 2: "Six Inch Cover" Rule: Use a modified specification such as a setup where a maximum of six (6) inches of soil cover is specified as the maximum allowable vertical space between top of newly installed PVC irrigation pipe and original soil grade elevations, within 20 feet of a tree trunk.

CONSULTING ARBORIST `� ASCA Registered Consulting Arborist #401 ISA Qualified Tree Risk Assessor ISA Certified Arborist #WC-3172 6.0 Tree Transplant Options Transplanting, depending on whether a tree is immediately moved and installed at another location, or is boxed up and held above ground with temporary irrigation for a number of months or years prior to permanent reinstallation at the transplant site, can cost on the order of $5,000 to $20,000 per tree for larger trees (e.g. a 15 inch diameter coast live oak, for example). Thus, the costs of transplant are generally infeasible in terms of the cost of transplant versus appraised dollar value of the tree. Typically, smaller diameter trees such as those 10 inches trunk diameter or less, in good overall condition (i.e. 70% overall condition rating or better), with upright, symmetrical branch and limb architecture are the best candidates for transplant. Larger diameter trees, older trees, trees in poor or fair condition, and specimens with asymmetrical root systems, sloping root systems on a non -level slope, and those which exhibit asymmetrical above -ground branch architecture, are for the most part not good transplant candidates. Trees currently proposed by the project team for transplant include two (2) protected -size California sycamore specimens protected by City tree ordinance: 1. Sycamore #260. This tree is in good overall condition, but is of relatively large diameter at over 15 inches diameter. The tree is an older specimen, and exhibits lean to the northeast as well as a canopy lopsided to the northeast. The asymmetrical nature of the tree's above -ground architecture, plus the fact that the root system could be limited or asymmetrical in the median planting area that it currently resides in, are negative factors when considering the tree for transplant. I suggest attempting to work around the tree, and retaining it during construction, rather than attempting to transplant this specimen. See the images section below in this report which shows the severe westward lean of the canopy. 2. Sycamore #416. This tree is in fair overall condition (50% out of 100% possible points), which is the lowest possible "fair" rating just 1 point above the threshold for "poor" (49%). The tree exhibits a lopsided canopy that extends eastward, and also exhibits a severe girdling root issue that downgraded the structural value of the tree to a 30%. This girdling root issue caused the overall condition rating to be bumped down to a 50%. Trees with lopsided canopies, and limited or otherwise asymmetrical root systems such as this tree with its girdling root problem, are poor candidates for transplant, especially since the overall condition rating is only 50%. Again, I suggest trying to retain the tree and work around it during construction. See the images section below which shows the tree's eastward lopsided canopy. In summary, WLCA recommends avoiding any transplants of existing trees at the Vallco site. If trees #260 and #416 are required to be removed due to issues related to conflicts with proposed new construction, then remove the trees, or redesign the project to work around the trees. Note that many trees currently proposed to be retained may need to be removed due to root loss and root damage that could occur during construction activities, especially during utility installations if those pipes and conduits are not installed using pit to pit bore technology to avoid trenching. 24 of 48 Site Address: Vallco Shopping Center, Cupertino, CA Version: 10/30/2015 © Walter Levison 2015 All Rights Reserved Registered Member, American Society of Consulting Arborists and Member of the International Society of Arboriculture Cell (415) 203-0990 / Email drtree(a),sbcalobal.net Walter Levison��.

Arborists are tree specialists who use their education, knowledge, training, and experience to examine trees, recommend measures to enhance the beauty and health of trees, and attempt to reduce the risk of living near trees. Clients may choose to accept or disregard the recommendations of the arborist, or to seek additional advice. Arborists cannot detect every condition that could possibly lead to the structural failure of a tree. Tree are living organisms that fail in ways we do not fully understand. Conditions are often hidden within trees and below ground. Arborist cannot guarantee that a tree will be healthy or safe under all circumstances, or for a specified period of time. Likewise, remedial treatments, like any medicine, cannot be guaranteed. Treatment, pruning, and removal of trees may involve considerations beyond the scope of the arborist's services such as property boundaries, property ownership, site lines, disputes between neighbors, and other issues.

Gilman and Dennis G. Watson2 INTRODUCTION Sequoia sempervirens, the Coast Redwoods of California, are the tallest trees in the world (Fig. 1). They can vary greatly when grown from seed, but varieties are available now which have been vegetatively propagated and they retain true characteristics. Redwoods grow three to five feet per year and are remarkably pest -free. They live to be many hundreds of years old; some live to several thousand years. Bark is particularly beautiful, turning a bright orange on older trees. It may grow poorly in zones 9 and 10 in Florida. GENERAL INFORMATION Scientific name: Sequoia sempervirens Pronunciation: see-KWOY-uh sem-per-VYE-rent Common name(s): Coast Redwood Family: Taxodiaceae USDA hardiness zones: 7 through 10A (Fig. 2) Origin: native to North America Uses: screen; specimen; no proven urban tolerance Availability: grown in small quantities by a small number of nurseries DESCRIPTION Height: 60 to 120 feet Spread: 25 to 35 feet Crown uniformity: symmetrical canopy with a regular (or smooth) outline, and individuals have more or less identical crown forms Crown shape: pyramidal Crown density: moderate Fact Sheet ST -589 October 1994 Figure 1.

Sequoia sempervirens -- Coast Redwood Page 2 Figure 2. Shaded area represents potential planting range. Foliage Leaf arrangement: alternate; spiral Leaf type: simple Leaf margin: entire Leaf shape: needle-like (filiform) Leaf venation: none, or difficult to see; parallel Leaf type and persistence: evergreen; needle leaf evergreen Leaf blade length: less than 2 inches Leaf color: green Fall color: no fall color change Fall characteristic: not showy Flower Flower characteristics: inconspicuous and not showy Fruit Fruit shape: oval; round Fruit length: .5 to 1 inch Fruit covering: dry or hard Fruit color: brown Fruit characteristics: does not attract wildlife; inconspicuous and not showy; no significant litter problem Trunk and Branches Trunk/bark/branches: droop as the tree grows, and will require pruning for vehicular or pedestrian clearance beneath the canopy; should be grown with a single leader; very showy trunk; no thorns Pruning requirement: needs little pruning to develop a strong structure Breakage: resistant Current year twig color: brown; green Current year twig thickness: medium; thin Wood specific gravity: 0.35 Culture Light requirement: tree grows in part shade/part sun; tree grows in full sun Soil tolerances: clay; loam; sand; slightly alkaline; acidic; occasionally wet; well -drained Drought tolerance: moderate Sequoia sempervirens -- Coast Redwood Other Roots: surface roots are usually not a problem Winter interest: tree has winter interest due to unusual form, nice persistent fruits, showy winter trunk, or winter flowers Outstanding tree: not particularly outstanding Invasive potential: little, if any, potential at this time Ozone sensitivity: tolerant Verticillium wilt susceptibility: not known to be susceptible Pest resistance: long-term health usually not affected by pests USE AND MANAGEMENT Redwood maintains a pyramidal form and dark green foliage throughout the year. Planted in a row 15 to 20 feet apart they make a nice screen. In areas outside California and the Northwest, it is probably best used occasionally as a novelty specimen. Redwood is tolerant of flooding, making best growth along stream banks and flood plains. Irrigation helps maintain a vigorous tree in other sites. Allow plenty of soil space for proper development. Propagation is possible from seed and through vegetative propagation. Pests Few insects were noted for Sequoia species. Diseases No diseases are of major concern. Sequoia sempervirens is resistant to oak root fungus. Page 3
