Bartlett Tree Expert Company Preliminary Arborist Report The Hamptons Parking Lot Expansion Cupertino, CA introduction and Overview The Irvine Company is preparing plans for the redevelopment of the subject property in Cupertino. The proposed project would enlarge existing parking into undeveloped areas. HortScience I Bartlett Consulting (Divisions of The F. A. Bartlett Tree Expert Co.) was asked to prepare a Preliminary Arborist Report for the project site for submission to the City of Cupertino. This report provides the following information: 1. An assessment of tree health, structure, and suitability for preservation. 2. A preliminary assessment of the impacts of constructing the proposed project and recommendations for action. 3. Preliminary tree preservation guidelines. Assessment Methods Trees were assessed on July 18, 2022. Trees with a diameter of 4 inches or greater were included in the assessment. The assessment procedure consisted of the following steps: 1. Identifying the tree species; 2. Tagging each tree with an identifying number and recording its location on a map; 3. Measuring the trunk diameter at a point 54 inches above grade; 4. Evaluating the health and structural condition using a scale of 1 — 5: 5 - A healthy, vigorous tree, reasonably free of signs and symptoms of disease, with good structure and form typical of the species. 4 - Tree with slight decline in vigor, small amount of twig dieback, minor structural defects that could be corrected. 3 - Tree with moderate vigor, moderate twig, and small branch dieback, thinning of crown, poor leaf color, moderate structural defects that might be mitigated with regular care. 2 - Tree in decline, epicormic growth, extensive dieback of medium to large branches, significant structural defects that cannot be abated. 1 - Tree in severe decline, dieback of scaffold branches and/or trunk; most of foliage from epicormics; extensive structural defects that cannot be abated. 5. Rating the suitability for preservation as "high", "moderate" or "low". Suitability for preservation considers the health, age and structural condition of the tree, and its potential to remain an asset to the site for years to come. High: Trees with good health and structural stability that have the potential for longevity at the site. Moderate: Trees with somewhat declining health and/or structural defects than can be abated with treatment. The tree will require more intense management and monitoring, and may have shorter life span than those in `good' category. Low: Trees in poor health or with significant structural defects that cannot be mitigated. Tree is expected to continue to decline, regardless of treatment. The species or individual may have characteristics that are undesirable for landscapes, and generally are unsuited for use areas. HortScience I Bartlett Consulting, Divisions of The F.A. Bartlett Tree Expert Company Preliminary Arborist Report, The Hamptons Parking Lot Expansion August2022 Page 2 Description of Trees Twenty-four (24) trees were assessed, representing five species (Table 1). Twelve (12) coast redwoods were in three groups across planting areas bordering parking. Eight London planes were dispersed throughout the same area. Chinese elm #188 was in the undeveloped area of the site. Off -site deodar cedar #203 and Aleppo pines #201 and 202 overhung the area's northern fence by approximately 1 — 2 feet. Overall, 16 trees were in good condition, six were in fair condition, and two were in poor condition. (Table 1). Descriptions of each tree are found in the Tree Assessment Form and approximate locations are shown on the Tree Assessment Map (see Exhibits).

Bartlett Tree Expert Company Preliminary Arborist Report, The Hamptons Parking Lot Expansion August2022 Page 3 The 12 redwoods distributed among three separate rows, each with four trees. They were generally young to semi -mature in development with trunk diameters varying between 4 to 22 inches and averaging 14 inches. Ten (10) trees were in good condition and trees #180 and 197 were in fair conditon. Trees in good condition had dense, vigorous crowns (Photo 1). The trees were receiving supplementary irrigation. Trees #180 and 197 were in fair condition, both having a slightly thin and suppressed crown due to crowding (Photo 1). Photo 1: Redwood #197 (far left) had a dense, vigorous crown, and an excurrent form. Redwood #198 (yellow) had a suppressed, thin crown. Twelve London planes were growing as stand-alone trees in planting basins throughout the parking area. Trees were generally young in development with trunk diameters between 5 and 12 inches, averaging 8 inches. Trees #190 — 192 were in good condition, each with a decurrent structure typical of the species and a vigorous crown (Photo 2). Trees #182, 185, and 186 were in fair condition with slightly less vigor, and each having a moderate lean. Trees #187 and 189 were in poor condition; they each leaned so severely that the base of the trunk was outside or nearly outside the dripline (Photo 3). Photo 2 (left): Tree #190 was in good condition with a vigorous crown. Photo 3 (right): Tree #185 leaned so severely that the base of the trunk was outside the dripline. HortScience I Bartlett Consulting, Divisions of The F.A. Bartlett Tree Expert Company Preliminary Arborist Report, The Hamptons Parking Lot Expansion August2022 Page 4 Chinese elm #188 was in fair condition. The tree had codominant trunks arising from the base and a short-statured, vigorous crown. Three off -site trees grew beyond the fence of the northern side of the undeveloped area: Aleppo pines #201 and 202, and deodar cedar #203. Trunks were approximately 10 feet north of the fence, and crowns overhung the site to the south by approximately 1 — 2 feet. Each of the three was in good condition. Suitability for Preservation Before evaluating the impacts that will occur during development, it is important to consider the quality of the tree resource itself, and the potential for individual trees to function well over an extended length of time. Trees that are preserved on development sites must be carefully selected to make sure that they may survive development impacts, adapt to a new environment and perform well in the landscape. Our goal is to identify trees that have the potential for long-term health, structural stability, and longevity. For trees growing in open fields, away from areas where people and property are present, structural defects and/or poor health present a low risk of damage or injury if they fail. We must be concerned, however, about safety in use areas. Therefore, where development encroaches into existing plantings, we must consider their structural stability as well as their potential to grow and thrive in a new environment. Where development will not occur, the normal life cycles of decline, structural failure, and death should be allowed to continue. Evaluation of suitability for preservation considers several factors: ■ Tree health Healthy, vigorous trees are better able to tolerate impacts such as root injury, demolition of existing structures, changes in soil grade and moisture, and soil compaction than non -vigorous trees are. For example, coast redwood #196 was in excellent condition. This tree would likely tolerate construction impacts more effectively. • Structural integrity Trees with significant amounts of wood decay and other structural defects that cannot be corrected are more likely to fail. Such trees should not be preserved in areas where damage to people or property is likely. London plane #185 had a severe lean. This tree would not be a good candidate for preservation in a planned use area. ■ Species response There is a wide variation in the response of individual species to construction impacts and changes in the environment. Coast redwood and London plane are both tolerant of root severance and general construction impacts. Deodar cedar is tolerant of root severance and moderately tolerant of general construction impacts. Aleppo pine is moderately tolerant of both root severance and general construction impacts. HortScience I Bartlett Consulting, Divisions of The F.A. Bartlett Tree Expert Company Preliminary Arborist Report, The Hamptons Parking Lot Expansion August2022 Page 5 Tree age and longevity Old trees, while having significant emotional and aesthetic appeal, have limited physiological capacity to adjust to an altered environment. Young trees are better able to generate new tissue and respond to change. Redwoods were young to semi - mature and able to adapt to change. Chinese elm #188 was mature, and likely less tolerant to change. Invasiveness Species which spread across a site and displace desired vegetation are not always appropriate for retention. This is particularly true when indigenous species are displaced. The California Invasive Plant Inventory Database (https://www.cal- pc.ora/paf/) lists species identified as being invasive. San Jose is part of the Central West Floristic Province. No species encountered is listed as having invasive potential. Each tree was rated for suitability for preservation based upon its age, health, structural condition, and ability to safely coexist within a development environment (Table 2). Table 2: Tree suitability for preservation. The Hamptons Parking Lot Expansion, Cupertino High Trees in good health and with structural stability that have the potential for longevity at the site. London planes #190 — 192 and off -site trees #201 — 203 had high suitability for preservation. Moderate Trees in fair health and/or with structural defects that may be abated with treatment. Trees in this category require more intense management and monitoring, and may have shorter lifespans than those in the "high" category. Chinese elm #188, London planes #185 and 186, and 11 coast redwoods had moderate suitability for preservation. Low Trees in poor health or with significant defects in structure that cannot be abated with treatment. These trees can be expected to decline regardless of management. The species or individual tree may possess either characteristics that are undesirable in landscape settings or be unsuited for use areas. London planes #182, 187, and 189, and coast redwood #198 had low suitability for preservation. We consider trees with high suitability for preservation to be the best candidates for preservation. We do not normally recommend retention of trees with low suitability for preservation in areas where people or property will be present. Retention of trees with moderate suitability for preservation depends upon the intensity of proposed site changes. HortScience I Bartlett Consulting, Divisions of The F.A. Bartlett Tree Expert Company Preliminary Arborist Report, The Hamptons Parking Lot Expansion August2022 Page 6 Preliminary Evaluations of Impacts and Recommendations Appropriate tree retention develops a practical match between the location and intensity of construction activities with the quality and health of trees. The Tree Assessment was the reference point for tree condition and quality. Impacts from construction were estimated given the project information available. To evaluate impacts from the project, I used the site plan (The Hamptons Apartment Homes ASA Submittal Set, Irvine Company) and communications with Jim Nguyen, Irvine Company. Plans were conceptual in nature. As such, the assessment of impacts to trees is preliminary. The development proposes to extend one parking lot into a currently undeveloped area, removing and replacing all vegetation surrounding the current parking stalls. Three parking stalls to a separate parking lot, replacing part of a planting basin. Not all trees were pictured on the site plan. I recommend a survey of accurate tree locations be depicted on all final plans. Based on my review of the plan, I recommend removal of 11 trees and preservation of 13 (Table 3). Trees #181, 183, 184, and 188 are located within the new paved area. Tree #185 is outside the paved area, but was identified for removal on the plan due to reduction in the size of the existing planting basin. I recommend removal of London planes #182, 187, and 189 as well. Each of the trees has a significant lean and low suitability for preservation. Tree #189 leans over the project area for the new parking lot. Trees #186 and 190 — 191, while not pictured on the plan, are in an area identified for removal of vegetation and stump grinding to a depth of 24 inches. This will remove the trees. Among trees recommended for preservation, coast redwood #180 is approximately 10 feet from the new parking lot project area. A portion of the tree's root area will be removed. Given the tree's size, fair condition, and coast redwood's tolerance of root severance and general construction impacts, I expect impacts to be moderate and within the tree's tolerance. Adequate irrigation should be continued throughout the construction process to support the tree's ability to adapt to impacts. Irvine Co. plans to preserve London plane #192. Since it is in an area identified for removal of vegetation and stump grinding, these impacts must be held away from the tree to allow for preservation success. Coast redwood #196 is approximately 9 feet from the new curb line cutting into the current planting basin. Given the tree's size, excellent condition, and coast redwood's tolerance of root severance and general construction impacts, I expect impacts to be moderate and within the tree's tolerance. As with tree #180, adequate irrigation for this tree is vital. Redwoods #197 — 200 are on the northern perimeter of the work area. Removal of current vegetation and stump -grinding to a depth of 24 inches is planned approximately 8 feet south of the four trees, extending parallel to the entire row. Plans depict preserving these four trees. I expect grinding to encounter significant amounts of roots, potentially removing approximately half of the tree's root area. The trees are currently well irrigated and generally in good condition. I expect impacts to be moderate to significant. Impacts could be minimized by cutting current vegetation at grade. Adequate irrigation will be key in attempting to preserve these trees. Coast redwoods #193 — 195 are distant from proposed work. I expect any impacts to these trees to be negligible to mild. HortScience I Bartlett Consulting, Divisions of The F.A. Bartlett Tree Expert Company Preliminary Arborist Report, The Hamptons Parking Lot Expansion August2022 Page 7 Off -site trees #201 — 203. The trees are approximately 10 feet away from the northern boundary of the new parking lot in an undeveloped area. I expect impacts to be within these trees' tolerances. The retention of all trees identified for preservation is predicated on adherence to the Preliminary Tree Preservation Guidelines. Cupertino Tree Protection Requirements The City of Cupertino Municipal Code 14.18.035 defines trees of certain species with a minimum single -trunk diameter of 10 inches or a multi -trunk diameter of 20 inches as protected. Of the species encountered, only deodar cedar was included. Tree #203 is Protected. No trees identified for removal are Protected. Individual designations are described in the Tree Assessment (see attachments). HortScience I Bartlett Consulting, Divisions of The F.A.

Bartlett Tree Expert Company Preliminary Arborist Report, The Hamptons Parking Lot Expansion August2022 Page 10 Preliminary Tree Preservation Guidelines The following recommendations will help reduce impacts to trees from development as well as maintain and improve their health and vitality through the clearing, grading, and construction phases. The key elements of a tree preservation plan for The Hamptons Parking Lot Expansion: Establishing Tree Protection Zones for each tree to be preserved. Tree Protection Zones are identified by the Consulting Arborist based on species tolerances, tree condition, trunk diameters and the nature and proximity of the proposed disturbance. Tree protection zones are identified on the Tree Preservation Plan (see attachments). ■ Providing supplemental irrigation prior to and during the demolition and construction phases. This is especially important for coast redwoods identified for preservation. Cupertino is outside of the native range of coast redwoods, and drought stress is very common in the area. Irrigation should continue throughout the project and afterwards. Design recommendations 1. All plans affecting trees shall be reviewed by the Consulting Arborist regarding tree impacts. These include, but are not limited to, demolition plans, grading and utility plans, landscape, and irrigation plans. 2. For trees identified for preservation, designate a Tree Protection Zone in which no construction, grading and underground services including utilities, sub -drains, water, or sewer will be located. Suggested layouts are depicted in the Tree Preservation Plan (see attachments). 3. No grading, excavation, construction, or storage of materials shall occur within that zone. 4. No underground services including utilities, sub -drains, water, or sewer shall be placed in the Tree Protection Zone. 5. Irrigation systems must be designed so that no trenching will occur within the Tree Protection Zone. 6. As trees withdraw water from the soil, expansive soils may shrink within the root area. Therefore, foundations, footings, and pavements on expansive soils near trees should be designed to withstand differential displacement. Pre -construction treatments and recommendations 1. The demolition contractor shall meet with the Consulting Arborist before beginning work to discuss work procedures and tree protection. 2. Where possible, cap and abandon all existing underground utilities within the Tree Protection Zone in place. Removal of utility boxes by hand is acceptable but no trenching should be performed within the Tree Protection Zone in an effort to remove utilities, irrigation lines, etc. HortScience I Bartlett Consulting, Divisions of The F.A. Bartlett Tree Expert Company Preliminary Arborist Report, The Hamptons Parking Lot Expansion August2022 Page 11 3. Fence all trees to be retained to completely enclose the Tree Protection Zone prior to demolition, grubbing or grading. Fences shall be 6 ft. chain link or equivalent as approved by the Consulting Arborist. Fences are to remain until all grading and construction is completed. Suggested fence layouts are depicted in the Tree Preservation Plan (see attachments). 4. Trees to be preserved may require pruning. All pruning shall be done by a State of California Licensed Tree Contractor (C61/D49). All pruning shall be done by Certified Arborist or Certified Tree Worker in accordance with the latest edition of the Best Management Practices for Pruning (International Society of Arboriculture) and adhere to the most recent editions of the American National Standard for Tree Care Operations (Z133.1) and Pruning (A300). The Consulting Arborist will provide pruning specifications prior to site demolition. Branches extending into the work area that can remain following demolition shall be tied back and protected from damage. 5. All tree work shall comply with the Migratory Bird Treaty Act as well as California Fish and Wildlife code 3503-3513 to not disturb nesting birds. Tree pruning and removal should be scheduled outside of the breeding season to avoid scheduling delays. Breeding bird surveys should be conducted prior to tree work. Qualified biologists should be involved in establishing work buffers for active nests. 6. Trees to be removed shall be felled so as to fall away from Tree Protection Zone and avoid pulling and breaking of roots of trees to remain. If roots are entwined, the consultant may require first severing the major woody root mass before extracting the trees, or grinding the stump below ground. 7. Apply and maintain 4-6 inches of wood chip mulch within the Tree Protection Zone. Recommendations for tree protection during construction 1. Prior to beginning work, the contractors working in the vicinity of trees to be preserved are required to meet with the Consulting Arborist at the site to review all work procedures, access routes, storage areas and tree protection measures. 2. All contractors shall conduct operations in a manner that will prevent damage to trees to be preserved. 3. Any grading, construction, demolition, or other work that is expected to encounter tree roots should be monitored by the Consulting Arborist. 4. Tree protection fences are to remain until all site work has been completed. Fences may not be relocated or removed without permission of the Consulting Arborist. 5. Construction trailers, traffic and storage areas must remain outside fenced areas at all times. 6. Prior to grading, excavation for foundations/footings/walls, filling, or trenching, trees may require root pruning outside the Tree Protection Zone by cutting all roots cleanly to the depth of the excavation. Roots shall be cut by manually digging a trench and cutting exposed roots with a saw, with a vibrating knife, rock saw, narrow trencher with sharp blades, or other approved root pruning equipment. The Consulting Arborist will identify where root pruning is required and monitor all root pruning activities. HortScience I Bartlett Consulting, Divisions of The F.A. Bartlett Tree Expert Company Preliminary Arborist Report, The Hamptons Parking Lot Expansion August2022 Page 12 7. If injury should occur to any tree during construction, it should be evaluated as soon as possible by the Consulting Arborist so that appropriate treatments can be applied. 8. No excess soil, chemicals, debris, equipment, or other materials shall be dumped or stored within the Tree Protection Zone. 9. Any additional tree pruning needed for clearance during construction must be performed by a Certified Arborist and not by construction personnel. Maintenance of impacted trees Preserved trees will experience a physical environment different from that pre -development. As a result, tree health and structural stability should be monitored. Occasional pruning, fertilization, mulch, pest management, replanting and irrigation may be required. In addition, provisions for monitoring both tree health and structural stability following construction must be made a priority. As trees age, the likelihood of failure of branches or entire trees increases. Therefore, annual inspection for structural condition is recommended.
