Planning Commission Staff Report -Page 4 16350 Blackberry Hill Road/S-14-067 August 12, 2015 ANALYSIS: A. Architecture and Site Analysis The applicant is proposing to construct a 711-square foot addition to the ex1stmg residence for a total of 4,661 square feet. The total proposed floor area including the 996- square foot basement and 1,052-square foot detached garage is 6,709 square feet. The applicant has an existing lower level with 2,252 square feet of floor area that IS considered a cell ar and not included in the floor area total pursuant to Town Code. The applicant is also proposing a new 527-square foot deck extension lo cated on the rear ofthe residence (see Sheet Al.2 ofExhibit 10).

Ce llars, as defined here, shall not be included in th e flo or area ratio calculation for residential developments. That area qf a cellar wh ere th e building heig ht exceeds.four (4)feet above existing orfinished g rade shall not be included in this definition and s hall be included in th e floor ar ea ratio calc ulatio n. For p urp ose s qf this definition whi chever grade (ex is tin g or proposed) r esults in th e lowes t building profile of a building s hall be used. **Pursuant to th e HDSG g arages up to 400 square f eet in area are not included in th e floor area ratio calculation . The propos ed addition to the east and west side of the rear of the single-family residence would maintain the existing structure height of 28 feet , nine inches. The propo sed additions would maintain the existing building height and would not increase the overall height of the residence. The addition would consist of stucco , wood trim, and a concrete tile roof to match the existing stucco , window trim , and roof material. Story poles have been placed on the site to aid in the review of the project. B. Neighborhood Compatibility Based on Town and County records , the re sidences in the immediate neighborhood range in size from 2 ,238 square feet to 8 ,857 square feet. The FAR ranges from 0.01 to 0.08. Planning Commission Staff Report-Page 5 16350 Blackberry Hill Road/S-14-067 August 12 , 2015 The applicant is proposing a 5,657-square foot home (not including cellar and garage square footage) on a 195 ,149-square foot parcel (0.03 FAR). The maximum allowed square footage for the lot size is 6 ,400 square feet. The Neighborhood Analysis table below reflects the current conditions in the immediate neighborhood.

(P) 5,657 1,452 195,149 0.03 The application is being considered by the Planning Commission because the residence wou ld be greater than 6,000 square feet in gross floor area and exceed the maximum allowable FAR. The maximum floor area is determined by the HDSG. However, pursuant to the HDSG, exceptions may be granted after carefully considering the constraints of the site. At 5,657 square feet, the residence would be the second largest based on square footage. Including the 1,052 square feet of garage floor area the residence would be 6, 709 square feet, 309 square feet larger than the maximum allowable FAR. The applicant provides rationale for the proposed project (Exhibit 6) stating that the lot coverage, setbacks, and FAR of the proposed project are compatib le with the development on the surroundings lots. C. Building Height The app lication is also being considered by the Planning Commission because the residence would exceed the maximum allowed building height pursuant to the HDSG. Planning Commission StaffReport-Page 6 16350 Blackberry Hill Road/S-14-067 August 12 , 2015 The existing home is visible from three of the four established viewing platforms located at the: 1. Southwest comer of Los Gatos Boulevard and Blossom Hill Road; 2. West of the Intersection of the Southbound Highway 17 on-ramp and Los Gatos- Saratoga Road (Highway 9); and 3. Northwest Comer of the Intersection ofW. Main Street and Bayview Avenue. As a result, the maximum building height from grade is 18 feet and the maximum height from the lowest point to the highest point is 28 feet. However, pursuant to the HDSG, the Planning Commission or Town Council may grant exceptions after carefully considering the constraints of the site. The applicant installed story poles and took photographs from the viewing platforms located at Los Gatos Boulevard and Blossom Hill Road, the Highway 17 on-ramp and Los Gatos-Saratoga Road , and the intersection of W. Main Street and Bayview Avenue (Exhibit 8). The photographs show the existing house is visible from the three viewing platforms and the proposed additions would also be visible . However, the applicant states that the proposed addition to the west side of the rear elevation is enclosing an existing balcony and would not create additional roof. The proposed addition to the east side of the rear elevation would create new roof area (Exhibit 6). The proposed addition on the east side of the rear elevation would result in maximum height of 16 feet, five inches from grade and the maximum height from the lowest point to the highest point is 28 feet , nine inches (see proposed north elevation -east side, Sheet A3 .4 , Exhibit 1 0). The proposed addition on the west side of the rear elevation would result in maximum height of 21 feet from grade and the maximum height from the lowest point to the highest point is 28 feet, nine inches (see proposed north elevation -west side, Sheet A3 .4 , Exhibit 1 0), which exceeds the 18 foot height limitation from grade and 28 foot height limitation from the lowest point to the highest point. The applicant is not proposing to create additional roof, but is proposing to enclose an existing covered area. The applicant provides rationale for the proposed project (Exhibit 6) stating that the building height for the addition would help blend with the exi sting res idence and maintain consistent architecture. Staff supports the proposed building height exception because: • The proposed addition to the east side of the rear elevation would meet the height standards of the HDSG for a visible home. • The proposed addition to the west s ide of the rear elevation does not meet the HDSG building height standards for a visible home; however, the existing residence Planning Co mmi ssion Staff Report -Page 7 16 3 50 Blackberry Hill Road/S-14-067 August 12 , 2015 c urrentl y exceeds the building he ight. The proposed addition is enclosing an existing roofed area that is 28 feet, nine inches and not increasin g the height or creating addi tion al roof. D. Tree Impacts The project plans were r eviewed by the Co nsulting Arborist and a report was prepared (Exhibit 7). There are fi ve protec ted tree s within the proposed constructi o n a rea, w hi ch include four Coast Live Oaks and one Blue Atlas Cedar. The proposal does not invol ve the removal of any existing trees to the property. The Town Arborist identified o ne five- inch Co ast Live Oak as "debatable" due to the cl ose pro ximity of the tree to a pier for the new deck ext ensio n. In this case, a debatable designation means that there may be a problem retaining the tree due to its location. If necessar y, the Coast Li ve Oak is recommended to be trans pl anted. Tree protection measures are incorporated as conditions of approval to protect the trees remaining on the subject pro perty within the development area. E. General Plan The goals and policies of the 2020 General P lan applicabl e to this project includ e but are not limited to : • Policy LU-6.8 -New construction, remodel s, and additions sh all be co mpatible a nd blend with the existing neighb o rhood . • Po li cy C D-1.2 -New structures, remodels , landscapes, and hardscapes shall be d es igne d to harmoni ze a nd blend with the scale a nd rh yt hm of the n e ighb o rhoo d and natura l features in the area. • Goal CD-14 -To preserve th e n atu ra l topography and ecosystems within the hill side area b y regulating grading, land scaping, and li g htin g. F. CEQA Determination The project is Catego ri call y Exempt pursuant to the adopted Guidelines for the Impl e mentation of the Cali fo rnia Env ironmenta l Quality Act, Section 1530 I : Existing Faci liti es. PUBLIC COMMENTS: At the time of thi s report's preparation, the Town has not received a ny public comment. Planning Commission Staff Report -Page 8 16350 Blackberry Hill Ro ad/S-14-067 August 12, 2015 SUMMARY AND RECOMMENDATION: A. Summary The project complies with the HDSG except for the request to exceed the maximum allowed floor area and building height. Pursuant to the HDSG, the Town Council or Planning Commission may grant an exception from the maximum floor area and building height standards. Exceptions may be granted after considering the constraints of the site and any compellin g reasons for granting an exception. B. Recommendation This application is being considered by the Planning Commission because the applicant is requesting an exception to the maximum allowable FAR and building height. The applicant 's request to exceed the maximum building height would maintain external consistency with the architecture of the residence. The proposed addition to the east side of the north elevation would create new roof area; however, the proposed height would meet the standards of the HDSG for a visible home. The proposed addi ti on to the west side of the north elevation does not meet the HDSG building height maximum for a visib le home; however, the proposed addition is enclosing an existing roofed area and not creating additional height. While staff supports the height exception, staff is recommending denial of the application because the proposal would exceed the maximum allowable FAR pursuant to the HDSG. C . Alternatives Alternatively, the Commission can: 1. Approve the application with additional or modified conditions of approval ; or 2. Continue the matter to a date certain with specific direction. If the Commission finds merit with the project and would like to approve the application, it should take the following actions: 1. Find that the proposed project is Categorically Exempt, pursuant to Section 15301 of the California Environmental Quality Act as adopted by the Town (Exhibit 2); and 2. Make the required findings as required by the HDSG for granting an exception to the maximum allowed floor area gr eater than 6,000 square feet in gross floor ar ea; and Planning Commi ssion Staff Report -Page 9 16350 Blackberry Hill Road/S-14-067 August 12 , 20 15 3. M ak e the required findin gs as required by the HDSG for granting an exce pti o n to the maximum allowed height of 18 feet ; and 4. Make the required findings as required b y th e HDSG for granting an exception to the maximum allowed height of 28 feet of a building 's tall est e levation measured from the lowest part of the building to the hi ghest part; and 5. Make the finding that o th er than th e exception to maximum allowed floor area and building height the project co mplies w ith the HDSG; and 6. Make the required considerations as required by Sectio n 29.20.150 of the Town Code for granting approval of an Architecture and Site application (Exhibit 2); and 7. Approve Architecture and Site Application S-14-067 with conditions contained in Exhibit 3 and development plans attached as Exhibit 10. It sh o uld b e noted that staff could not make all of the findin gs in Exhibit 2. Exhibit 2 must be modified with respect to the HDSG and the r equ est to exceed the maximum floor area if the Planning Commission find s merit to approve the proj ect. The Commissio n should identify s pecific fact s to s upport the findings such as the circumstances of this application. Jocelyn G. Puga Assistant Planner LRP:JGP:cg Approved b y: Laurel R .

Main Street and Bayview A ve nue. 2. There will be no significant impacts on protected trees, wi ldlife habitat or movement corridors. There are five protected trees within the proposed construction area with one five- inch Coast Live Oak identified as debatable by the Consulting Arborist due to the close proximity of the tree to a pier for the new deck extension. 3. Any grading necessary to accommodate the building area that exceeds the allowed FAR or any accessory building will be minimized. No grading is proposed as part of this application. 4. All standards and applicable guidelines are being met. The project complies with the Hillside Development Standards and Guidelines except for the request to exceed the maximum allowed floor area and building height. IXBIBIT 2 5. Compliance to Title 24 Energy Efficiency Standards are shown usmg computer methods. The compliance margin must be at least 1 0.0. A preliminary Build It Green checklist was completed by the applicant and shows that the project will exceed the minimum number of points (50) needed to achieve certification with a score of I 02. 6. The house will be pre-wired for future photovoltaic (PV) installation. The residence is not pre-wired for future photovoltaic (PV) installation. 7. A minimum of 25% of hardscape material is permeable (certain types of interlocking pavers, grasscrete, pervious concrete, etc.) The property has 7,705 square feet of paved area for a total of3.9 percent the total gross lot area that contains hardscape material. 8. A significant cellar element is included in the design, unless it conflicts with other standard s. The existing single family residence has a 2,252-square foot cellar. 9. There will not be a significant visual impact to neighboring properties. The most immediate property is approximately 125 feet to the east. The proposed additions are on the rear of the property and will not cause a significant vis ual impact to the immediate neighbor to the east. Exception to Maximum Allowable Building Height: • The Commission may grant an exception to the maximum allowed height of 18 feet pursuant to Chapter IX, section F. of the Hill si de Development Standards & Guidelines for single-family residences visible from the established viewing platforms. Any deviation shall include the rationale and evidence to support the granting of an exception.

My husband and I have lived in Los Gatos for more than seven years and moved from our previous home on Bicknell Road to our new home a year ago in September 2013. Since that time, we have been considering how to tum this house into a home that will suit our plans to start a family. The existing home has ample living space but is configured in such a way that it does not naturally accommodate fluidity or connection within the home. For instance, there is a Master bedroom upstairs and three other bedrooms downstairs that are not easily accessible from the upstairs bedroom. Our proposed changes include the addition of two bedrooms adjacent to the Master to alleviate this issue and prepare for the arrival of children in the near future. Additionally, the current family room is the furthest room on the main floor from the kitchen. Having lived only in homes where the family room was adjacent to the kitchen, we can sense the discord and lack of unity in our home when we have family and friends over and can project experiencing the same sense of disconnection dl,lring a future time in which there are young children present. Therefore, we are proposing building a family room directly adjacent to the kitchen. The remaining updates primarily serve to bring a sense of warmth and light into the home; with its cold and dark tile floors , narrow entrance to the kitchen and enclosed stairs to access the bottom floor, the house is not as bright and inviting as would reflect our taste and preferences. We believe the changes we are proposing would greatly improve the functionality and aesthetic of our home in countless, positive ways. We look forward to establishing our permanent residence here on Blackberry Hill with your support and appreciate your consideration of our plans. You may feel free to contact me directly if you have any questions.

Main St. Los Gatos, CA 95030 Subject: Sarafan-Ghorbani Residence/16350 Blackberry Hill Rd. Dear Ms Puga: RECEIVED JUN 1 7 2015 TOWN OF LOS GATOS PLANNING DIVISION This letter is to describe the purpose of the proposed changes at the existing residence at 16350 Blackberry Hill Rd. The Sarafan-Ghorbani family wishes to modify their home in preparation for their growing family. They are planning to have children in the near future and hope to redesign their home in a way that is better suited to the daily functions of their family. While the existing home has ample square footage, it is currently configured in a way that is discordant with the needs of their growing family; they wish to have an efficient space for daily living that is also conducive to easy interaction amongst and connection between the family. Therefore, the proposed changes include: adding two bedrooms near the existing master bedroom so they can be in close proximity to their children's bedrooms in the future. They also wish to add a family room off of the existing kitchen so they can be close to their children's' daily activities and readily available to them even when they are involved in their own activities . Due to the configuration of the home we are adding mostly under the existing roof structure. The only room that is having a new roof is the family room. The existing roof of the house is currently set at 28 '-9". The new family room has a height of 25 ', which exceeds 18' required by Town of Los Gatos. The only way we can give a 10' ceiling height in this new room , maintain the floor levels and keep the architecture consistent externally is to maintain a minimum 25' height. We, as the architects, have looked at different scenarios to reduce the height but we have realized that lowering the roof more then 25' will greatly affect the existing architecture and building lines. We have held the new addition back from the existing house line by a few feet just for the purpose of blending in and creating the new addition as if it was part of the original home. Even though the two roof heights are not the same, we believe we have managed to address th e height issue with an elegant architectural roofline. 4546 EL Camin o Real Suite 223 • Los Alto s.CA.94022 • 650.565.9036 • (f) 949 .625.7869 • www.md esignsarchitects.com EXHIBIT 6 Where the findings are concerned we believe the project meets all the findings: 1) The Design theme, scale, materials and details are all consistent with: - a.

Residential development 2) The lot coverage, setbacks and FAR of the proposed project is compatible with the development on surrounding lots. The Sarafan-Ghorbani family believes these changes will greatly affect their family in a positive way. They are open for recommendation from the commission to add landscaping if necessary. We hope that th e commission can see the benefit of this project and will approve this so that the homeowners can proceed forward with their future planning.

Arborist Report for 16530 Blackberry Hill Rd . May 20, 2015. Page 2 of 25 Deborah Ellis, MS Consulting Arborist & Horticulturist Service since 1984 RECOMMENDATIONS 1 . Existing trees to be saved or removed should be numbered on all site-based plans to match the tree tag numbers that are used in this arborist report. 2. Trees listed as "Debatable" are: #2 and 3 . Read about these two trees in the Notes Section of the Complete Tree Table in order to determine what to do with them (will they be saved or removed)? A "Debatable" designation means that there is a problem with retaining that tree, such as a tree that is shown to be saved but is a poor species for the site , or in poor condition. Another common cause is that the tree is shown to be saved but construction may be too close to it. The reason for the "Debatable" designation can be found in the "Reason" and "Notes" column of the Complete Tree Table. Additional action or decisions are necessary on the part of the tree owner, project architects or others involved in the project design and construction are necessary in order to resolve whether a debatable tree will be saved or removed . 3. For those trees that will be retained on the site, follow the Town of Los Gatos Tree Protection Directions, included in this report on pages 17 through 19. A separate copy of the Directions is enclosed and must be incorporated into the project final plans . Additional tree protec tion information is also available from Deborah Ellis if necessary. a. Regarding coast live oak #1 , the opening below the existing patio/deck must be fenced off and have tree protection signage placed on the fencing so that workers will not store materials and equipment in this area . Above the deck the trunk of the tree up to the height of the lowest branch facing the house must be wrapped w ith Type 3 Tree Protection (straw wattle roll). 4. Neighboring trees: whose canopies overhang the project site adjacent to construction must receive tree pro tection in the same manner as existing trees to remain on the project site ; for example tree protection fencing and signage. The general contractor shall fence off the dripline of these trees as much a s possible in order to avoid damaging branches and compacting the soil beneath the canopy. If pruning is necessary in order to avoid branch breakage, the general contractor shall hire a qualified tree service to perform the minimum necessary construction clearance pruning. 5. I should review all site -based plans for this project: I have reviewed the plan sheets listed on page 6. Additional improvements on plans that were not reviewed or have been revised may cause additional trees to be impacted and/or removed. Plans re viewed by the arborist should be full-size , to-scale and with accurately located tree trunks and canopy driplines relative to proposed improvements . Scale should be 1 :20 or 1:10. I PO Bo x 3714, Saratoga, CA 95070. 408-725-1357. decah@pacbell.net. http://www.decah.com. I Arborist Report for 16530 Blackberry Hill Rd. May 20, 2015 . Page 3 of 25 De borah Ellis, M S Consulting Arborist & Horticulturist Service since 1984 6. As a part of the design process, try to keep Improvements (and any additional over-excavation or work area beyond the Improvement) as far from tree trunks and canopies as possible. SxDBH2 or the dripline of the tree, whichever is greater, should be used as the minimum distance for any soil disturbance to the edge of the trunk. 3xDBH should be considered the absolute minimum distance from any disturbance to the tree trunk on one side of the trunk only, for root protection. Farther is better, of course. For disturbances on multiple sides of the trunk, then 5xDBH or greater should be used, and farther is also better here. Tree canopies must also be taken into consideration when designing around trees . Don't forget the minimum necessary working margin around improvements as you locate those improvements. Disturbance usually comes much closer to trees than the lines shown on the plans! 7. Construction or landscaping work done underneath the drlpllne of existing trees should preferably be done by hand, taking care to preserve existing roots in undamaged condition as much as possible and cutting roots cleanly by hand when first encountered, when those roots must be removed. A qualified consulting arborist (the project arborist) should be hired to monitor tree protection and supervise all work underneath the dripline of trees. This also applies to trees on neighboring properties whose canopies overhang the work site. 8. Landscaping: a . New landscaping and irrigation can be as much or more damaging to existing trees than any other type of construction . The same tree root protection distances recommended for general construction should also be observed for new landscaping. Within the root protection zone it is usually best to limit landscape changes to a 3 to 4-inch depth of coarse organic mulch such as wood or bark chips or tree trimming chippings spread over the soil surface. The environment around existing trees should be changed very carefully or not at all -please consult with me regarding changes in the landscape around existing trees and/or have me review the landscape and irrigation plans for this project. b. This site contains oaks that are native to the immediate area (coast live oaks #1, 2, 3 and 4 ). This tree species fares best with no irrigation during the normal dry months of the year. The best treatment of the ground beneath the canopies of native oaks is nothing but their own natural leaf and twig litter mulch. Exceptions to irrigation restriction include during the winter in extended drought periods, as temporary compensation for root loss due to construction, and for newly planted trees during their 2 to 3 year establishment period after installation. Native oak species are often killed due to inappropriate landscaping that is installed around them; mostly commonly landscaping that requires frequent irrigation such as lawns or other high water- use plants . Large drought tolerant trees such as native oaks can become dangerous when exposed to frequent irrigation, especially close to their trunks. California native oaks that are treated in this manner may contract root rot diseases and fall 2 3 & SxDBH : See oaae 16 for an exolanation of these calculations which are used to estimate root orotection distances for trees .

Page 4 of 25 Deborah Ellis, MS Consulting Arborist & Horticulturist S ervice si nce 1984 over at the roots; often causing great damage and personal injury I there are targets in their vicinity such as h omes, cars and people. It is important to landscape c orre c tly around our native oaks; e.g. summer dry. I have attached a publication entitled living among the Oaks, to assist in best managing the oaks on the property, as well as the directions to follow in items 'b' and 'c' below. c. Around th e native oaks: there shall be no planting or irrigation (including drip irri gation} within a minimum radius of 10 fe et from the trunks of the oaks or the inner half of the dripllne of the tree, whichever is greater. Farther is better. Within this 10-foot (or greater} radius around the trunk a 3 to 4-inch depth of coarse organic mulch such as wood or bark chips or tree trimming chippings sha ll be spread over the soil surface. Shredded redwood bark is not allowed. Keep the mulch off the root collar of the trees. Beyond this 10-foot (or greater) protective, mulched area only drought-tolerant, summer-dry plant species, preferably plant species that are na tive to the immediate area and grow commonly in association with the native oaks, may be planted. Only summer-dry tolerant plants are allowed within the outer half of the dripline of the tree or 20 feet from the trunk, whichever is greater. Suc h plants may be planted from no larger than 1-gallon cans in holes that are hand-dug manually with a shovel (no power equipment such as augers allowed). The se plants must be spaced sparsely (e.g. p lanted no closer than 4 feet apart) and watered with drip irrigation. The planting zone around these plants shall be mulched in the same manner previously described. The drip irrigation for these plants should preferably be abandoned after a 2 to 3 year es tablishme nt period. 9. General Tree Maintenance: a. The root collars and lower trunks of some of the trees were obscured from view by vegetation, excess soil or other covering.

The purpose of the report is to identify and describe the existing protected trees on site --their size , condition and suit a bility for preservation. The audience for this report is the property owner, developer, project architects and contractors, and Town of Lo s G atos authorities concerned with tree preservation and tree removal. The goal o f this report is to preserve the existing protected trees on site that are in acceptable c ondition, are good species for the area and will fit in well with the proposed new use of the site.

Page 6 of 25 Deborah Ellis, MS Consulting Arborist & Horticulturist Service si11ce 1984 METHODOLOGY I performed a brief evaluation of the subject trees on May 14, 2015. Tree characteristics such as form, weight distribution, foliage color and density, wounds and indicators of decay were noted. Surrounding site conditions were also observed. Evaluation procedures were taken from: • Guide for Plant Appraisal, 9th edition, 2000, authored by the Council of Tree and Landscape Appraisers (CTLA) and published by the International Society of Arboriculture (ISA). • Species Classification and Group Assignment published by the Western Chapter of the International Society of Arboriculture (WCISA), 1992. The above references serve as industry professional standards for tree and landscape evaluations. I measured the trunk diameter of each tree w ith a diameter tape at 3 feet above the ground, which is the required trunk diameter measurement height of the Town of Los Gatos. Trunk diameter was extrapolated to DBH (diameter at breast height, 4.5 feet above the ground) because DBH is also used calculate tree protection distances and other tree-related factors. The DBH figure is not included in the Tree Tables, but I have used it to estimate construction impacts to trees. Trunk diameter was rounded to the nearest inch. I estimated the tree's height and canopy spread. Tree Condition (structure and vigor) was evaluated and I also recorded additional notes for trees when significant. Tree species and condition considered in combination with the current or (if applicable) proposed use of the site yie lds the Tree Preservation Suitability rating. The more significant trees (or groups of trees) were photographed with a digital camera. Some of these photos are included in this report, but a ll photos are available from me by email if requested.

Page 7 of 25 OBSERVATIONS SITE CONDITIONS Deborah Ellis, MS Consulting Arborlst & Horticulturist Seroice since 1984 There is an existing two-story, single-family house on the site; also a pool and landscaping that is typical for the Los Gatos hillside area . Site topography is level around the house, but then slopes steeply down to the North. Most of the vegetation on the site is native and probably of natural growth, although there are some non-native ornamental plants planted near the house . Landscape maintenance is of a moderate level. TREES ON NEIGHBOR ING PROPERTIES There are some large native oak trees that overhang the North perimeter of the site, near coast live oak # 1 . The canopies of these trees have been pruned to be fairly high, but the trunks of some of the trees are close to the fence between the two properties. There is one large coast live oak in particular, shown in the photo on page 20, whose canopy should be fenced off as much as possible in order to reduce soil compaction caused by construction traffic and storage.

I Arbori st Report for 165 30 Blackberry Hill Rd . May 20, 2015. Page 11 of 25 De b orah E llis, MS Consulting A rboris t & Horticulturist S ervice sin ce 1984 EXPLANATION OF TREE TABLE DATA COLUMNS: 1) Tree Number (the field tag number of the existing tree). Each existing tree in the field is tagged w ith a 1.25 inch round alumi num number tag that corresponds to its tree number referenced in the arborist report, Tree Map, Tree Protection Directions and any other project plans where ex isting trees must be shown and referenced. 2) Tree Name and Type: Species: The Genus and species of each tree. This is the unique scientific name of the plant, for example Quercus agrifolia where Quercus is the Genus and agrifolia is the species. The scientific names of plants can be changed from t ime to time, but those used in this report are from the most current edition of the Sunset Western Garden Book (2012) Sunset Publishing Corporation. The scientific name is presented at its first occurrence in the Tree Table, along with the regional common name. After that only the common name is used . 3) Trunk diameter (at 3 feet above the ground). This is the trunk diameter measurement height required by the Town of los Gatos, in lieu of DBH3 • For multi-trunk trees, trunk diameter is measured for the largest trunk and estimated for all smaller trunks . A number in parentheses (e.g. 2) after the trunk diameter(s) indicates that it was not possible to measure the trunk at 3 feet (due to tree architecture) and so the diameter was measured at th is alternate height (in feet), which reflects a more realistic trunk diameter for the tree. Examples: an "18" in the Diameter column means that the tree has a diameter of 18 inches at 3 feet above the ground. An "18 (2)" means that trunk diameter wa s 18 inches measured at 2 feet above the ground. "18, 7, 5" means that this is a multi-trunk tree with trunk diameters of 18, 7 and 5 inches at 3 feet above the ground. 4) Size : tree size is listed as height x width i n feet, estimated and approximate and intended for comparison purposes. 5) Condition Ratings: Trees are rated for their condition on a scale of zero to 100 with zero being a dead tree and 100 being a perfect tree (which is rare- like a supermodel in human terms). A 60 is "average" (not great but not terrible either). There are two components to tree condition -vigor and structure, and each component is rated separately. Averaging the two components is not useful because a very low rating for either one could be a valid reason to remove a tree from a site--even if the other component has a high rating. Numerically speaking for each separate component: 100 is equivalent to Excellent (an 'A' academic grade), 80 is Good (B), 60 is Fair (C), 40 is Poor (D), 20 is Unacceptable (F) and 0 is Dead . 3 DBH is t ree t runk diameter m mches "at breast heigh t", measured at 4.5 feet above ground level. This is the fo restry and ar boricultural standard measurement heiaht t hat is also used in manv tree-related calculations.

The tree owner may contact Deborah Ellis for additional information on tree conditio n an d specifi c recommendations for the general care of individual trees relative to their condition. 7) The Condition of the tree is considered relative to the tree species and present or future intended use of the site t o provide an opinion on the tree's Preservation Suitability Rating (i.e . "Is this tree worth keeping on this site , in this location, as expla ined in Table 4 below. This is based upon the scen ari o that the tree is given enough above and below-ground space to survive and live a long life on the site. Ratings such as "Fair/Good" and "Fa ir/Poor" are intermed iate i n nature . The Preservation Suitability rating is not always the same as the Condition Rating becau se (for example) some trees with poor co ndition or structure can be significantly improv ed with just a small amount of w ork-and it would be worthwhile to keep t he tree if this were done. Table 4 P 1tion SuitabilitY Ratina E 'I ~r- Such trees are rare but they have unusually good health and struct ure and provide Excellent multiple functional and aesthetic benefits to the environment and the users of the s ite. These are great trees with a minimum rating of "Good" for both vigor and structure . Equivalent to academic grade 'A '. These trees may have some minor to moderate structural or condit ion flaws that can be Good improved with treatment. They are not perfect but they are in relatively good condition and provide at least one significant functional or aesthetic benefit to the environment and the users of the site. These are better than average trees equivalent to academ ic grade · B'. These trees have moderate or greater health and/or structural defects that it may or may not be possible to improve with treatment. These are "average" trees -not great but not so terrible that they absolutely should be removed . The majority of trees on most s ites Fair tend to fall into th is category. These trees will require more intensive management and monitoring , and may also have shorter life spans than trees in the "Good" category. Retention of trees with moderate suitability for preservation depends upon t he degree of proposed site changes . Equivalent to academic grade ·c·. These trees have significant structural defects or poor health that cannot be reasonably improved with treatment. These trees can be expected to decline regardless of Poor management. The tree species themselves may have characteristics that are undesirable in landscape settings or may be unsuitable for high use areas. I do not recommend retention of trees with low suitability for preservation in areas where people or property will be present. Equivalent to academic grade ·o ·. These trees are dead and /or are not suitable for retention in their location due to ris k or None other issues. In certain settings however, (such as wilderness areas, dead trees are beneficial as food and shelter for certain animals and plants including decomposers. -------------------j;gl,!iy~IEmt t() ~cademif_flr~de_·F'. -- I PO Box 371 4, Saratoga , CA 95070. 408-725-1357. decah@pacbell.net. http://www.decah.com.

Page 13 of 25 Deborah Ellis, MS Consulting Arborist & Horticulturist Service since 1984 8) Action (Disposition): a) Save : it should be no problem save this tree utilizing standard tree protection measures. b) Remove: this recommendation is based upon tree condition, preservation suitability, expected impact of construction, poor species for the site or any combination of these factors. c) Debatable: there is a problem with potentially retaining this tree. Find out why in the Reason and Notes columns of the Complete Tree Table. Examples are: • The tree is shown to be saved (and may be a desirable tree to save) but proposed construction is too close or is uncerta in and may cause too much damage to retain the tree. Design changes may be recommended to reduce damage to the tree so that it can be saved. • Further evaluation of the tree is hecessary (e.g. the tree requires further, more detailed evaluation that is beyond the scope of this tree survey and report. Examples are advanced internal decay detection and quantification with resistance drilling or tomography, a "pull test" to assess tree stability from the roots, or tissue samples sent to a plant pathology laboratory for disease diagnosis. • Condition : the tree is in "so-so" or lesser condition and an argument could be made to either save or remove the tree as it stands now. In some cases the owner will make the decision to save or remove the tree based upon the information provided i n this report as well as the owner's own preferences . • Species: the tree may be a poor species for the area or the intended use of the developed site. • Uncertain construction impact • Other (as explained for the individual tree) 9) Reason (for tree removal or to explain why a tree is listed as "Debatable" or "Uncertain"). Multiple reasons may be provided, with the most significant reason listed first. Reasons can include but are not limited to: • Construction (excessive con struction impact is unavoidable and it is not worthwhile to try and save the tree) • Condition (e .g. poor tree condition-either vigor, structure or both) • Landscaping (the tree is being removed because it does not fit in with or conflicts with proposed new landscaping) • Owners Decision (f or some rea son the owner has decided to remove this tree) • Species (the tree is a poor species for the use of the site) • Risk (the tree presents moderate to excessive risk to people or property that cannot be sufficiently mitiga ted) 10) Notes: This may include any other information that would be helpful to the client and their architects and contractors within the scope of work for this report, such as a more detailed explanation of tree condition or expected construction impact.

For multi-trunk trees 100% of the DBH of the largest trunk is added to 50% of the DBH for all other trunks in order to compute the operational DBH to use for these the Tree Protection Dista nc e calculations. For practical purposes, the minimum 3xDBH distance listed is 3 feet and the m inimum SxDBH distan ce is 4 feet. If disturbance cannot be ke pt at lea st 3 feet from the trunk of a tree, the tree should norma lly be removed . ii) OTPZ (Optimum Tree Protection Zone): Thi s is calculated as per the text, Trees & Development. Matheny et al., International Society of Arboriculture, 1998. Thi s method takes into account tree age and the particular t ree sp ecies tolerance of root d isturbance. Becau se it may not be possible to maintain the OPTZ di stance recommended for trees on many projects due to crowded site cond itions, the Arborist may omit th is r equ irement and list only the 3 and SxDBH distances. b) Canopy Protection : Additional space beyond root zone protection d ista nce s ma y be necessary for canopy protection . c) I have increase d a few of the calculated tree protection distances for individua l trees based u po n my professional judgment re lative to site constraints.

Page 15 of 25 TREE PROTECTION DISTANCES 3 TO 5 X DBH Debo ra h Ellis, MS Consulting Arborist & Horticulturist Service sin ce 1984 No one can estimate and predict with absolute certainty how far a soil disturbance such as an excavation must be from the edge of the trunk of an individual tree to affect tree stability or health at a low, moderate or severe degree--there are simply too many variable involved that we cannot see or anticipate. 3xDBH however , is a reasonable "rule of thumb" minimum distance (in feet) any ex-cavation should be from the edge of the trunk on one side of the trunk. This is supported by several separate research studies including (Smiley , Fraedrich , & Hendrickson 2002 , Bartlett Tree Research Laboratories. DBHis trunk "diameter at breast height" (4 .5 feet above the ground). This distance is often used during the design and planning phases of a construction project in order to estimate root damage to a tree due to the proposed construction. It tends to correlate reasonably well with the zone of rapid toper, which is the area in which the large buttress roots (main support roots close to the trunk) rapidly decrease in diameter with increasing distance from the trunk. For example, us ing the 3X DBH guideline an excavation should be no closer than 4.5 feet from the trunk of an 18-inch DBH tree. Such distances are guidel ines only , and should be increased for trees with heavy canopies, significant leans, decay , structural problems , etc. It is also important to understand that in actual field conditions we often find that much less root damage occurs than was anticipated by the gu idelines. 3x DBH may be more of an aid in preserving tree stability and not necessarily long-term tree health. 5X DBH or greater is the "preferred" minimum distance which should be strived for , and this distance or greater should probably be used when there are multiple trenches on more than one side of the trunk. The roots beyond the zone of rapid taper form an extensive network of long, rope-like roots one to two inches in diameter. These woody perennial roots are referred to as transport roots because they function primarily to transport water and minerals. Maintaining a 5xDBH tree protection zone or greater around a tree will preserve more of these transport roots, which will have less of an impact on tree health than if the excavation were closer to the trunk. OTPZ (OPT IMUM TR EE PRO TECTION ZONE) OTPZ is the distance in feet from the trunk of the tree, all around the tree, that construction or other disturbance should not encroach within. If this zone is respected, then chances of the tree surviving construction disturbance are very good . This method takes into account tree age , DBH and the particular species tolerance to root disturbance. Although there are no scientifically based methods to determine the minimum distance for construction (for example , root severance) from trees to assure their survival and stability , there are some guidelines that are often used in the arboricultural industry. The most current guideline comes from the text, Trees & Development, Matheny et al., International Society of Arboriculture, 1998. The tree protection zone calculation method in this text was used to obtain the OTPZ's provided in this report. Due to the crowded, constrained nature of many building sites it is often not be possible to maintain the OPTZ distance recommended for many of the trees --therefore I have also listed alternate distances of 3 and 5X DBH (see paragraph above).

Tree locations were provided b y an unknown party and are shown on the Tree Map on page 1 of this report. The tree map is a reduced partial copy of the proposed Site Plan that I was given. Tree locations are assumed to be accurate but should b e veri fied in the field. 2. Some of the trees described In this report were not Included on the plans (trees #2, 4 and s ) and so we tentat ively plotted t he approximate locations of the trunks of these trees on the Tree Map. At least tree #2 should be accurately shown on all si te-based plans so that I can accurately estimate the impact of construction to this tree. 3. A Basic Evaluation of the subject trees described In this report was performed on May 14. 2015 for the purpose of this report. A bas ic evaluation is a visual evaluation of the tree from the ground. wi thout c limbing into the t ree o r performing detailed tests such as extensive digging. boring or removing samples. This is a n initial screening of th e tree after which the evaluator may recommend that additional. more detailed examination(s) be performed if deemed necessary . 4. Trees on neighboring properties were not evaluated. They were only viewed cursorily from the proj ect site. I d id not enter the neighboring property to inspect these trees up close . 5. Some trees had their root collars and or lower trunks covered with soil. vegetation o r debris and were obs tructed fro m view w hen I conducted my tree evaluation. If these trees may remain . the obstructions should be removed and I should re -examine these previously covered areas. 6. Any Information and descriptions provided to me for the purpose of my Investigation In this case and the p reparation of this report are assumed to be correct. Any titles and ownerships to any property are assumed to be good and marketable. I assume no responsibility for legal matters in character nor do I render any opinion a s t o the quality of any title. 7. The Information contained In this report covers only those items that were examined and reflects the conditi on of those items at the time of in spection. 8. Loss or removal of any part of th is report invalidates the entire report. 9 . Possession of this report. or any copy thereof. does not Imply right of publication for use for any purpose by any person othe r than to whom this re p ort is addressed without my written consent beforehand. 10. This report and the ratings or values represented herein represent my opinion. My fee is in no way contingent upon t he reporting of a specified value or upon any finding or recommendation reported. 11 . This report has been prepared In conformity with generally acceptable appraisal/diagnostic/reporting methods and procedures a nd is consistent with practices recommend ed by the In t e rnati o nal Socie ty of Arboricu lture and the American Society of Consu ltin g Arborists. 12. My evaluation of the trees that are the subject of this report Is limited to visual examination of accessible items without dissection. excavation. probing or coring. Th ere is no warranty or guaran tee. expressed o r implied. that problems or deficiencies o f the plants o r property in question may no t arise in the future.

Page 22 of 25 Deborah Ellis , MS Consulting Arborlst & Horticulturist Service since 1984 13. I take no responsibility for any defects In any tree's structure. No tree described in this report has been climbed and examined from above the ground, and as such, structural defects that could only have been discovered have not been reported, unless otherwise stated. Structural defects may also be hidden within a tree, in any portion of a tree. Likewise , root collar excavations and evaluations have not been performed unless otherwise stated. 14 . The measures noted within this report are designed to assist In the protection and preservation of the trees mentioned here in, should some or all of those trees remain, and to help in their short and long term health and longevity. This is not however; a guarantee that any of these trees may not suddenly or eventually decline, fail, or die, for whatever reason. Because a significant portion of a tree's roots are usually far beyond its dripline, even trees that are well protected during construction often decline, fail or die. Because there may be hidden defects within the root system, trunk or branches of trees , it is possible that trees with no obvious defects can be subject to failure without warning. The current state of arboricultural science does not guarantee the accurate detection and prediction of tree defects and the risks associated with trees. There will always be some level of risk associated with trees , particularly large trees. It is impossible to guarantee the safety of any tree . Trees are unpredictable. ****************************** I certify that the information contained in this report is correct to the best of my knowledge, and that this report was prepared in good faith .

T he arborist who is appointed to be in charge of arborist services for the project. That arborist shall also be a qualified c onsulting arborist (either an International Society of Arboriculture (ISA) Board-Certified Master Arborist or an American Soc iety of Consulting Arborists (ASCA) Registered Consulting Arborist) that has sufficient knowledge and experience to perform the specific work required . For most construction projects that work will include inspection and documentation of tree protection fencing and other tree protection procedures, and being available to assist with tree-related issues that come up during the project. 2. Arborist. Qual ified Consulting: must be either an International Society of Arboriculture (ISA) Board-Certified Master Arborist or an Ameri can Society of Consulting Arborists (ASCA) Registered Consulting Arborist that has sufficient knowledge and e xperience to perform the specific work required . 3. Dri plin e: the area under the total branch spread of the tree, all around the tree. Although tree roots may extend out 2 to 3 times the radius of the dripline, a great concentration of active roots is often in the soil directly beneath this area. The dripline is often used as an arbitrary "tree protection zone". 4. Tree Service. Qualified: A tree service is a company that performs tree pruning and tree removals as their main business. A Qualified Tree Service is a tree service with a supervising arborist who has the min imum certification level of ISA (International Society of Arboriculture) Certified Arborist and acts in a supervisory position on the job site during execution of the tree work . The tree service shall have a State of California Contractor's license for Tree Service (C61-D49) and provide proof of Workman 's Compensation and General Liability Insurance. The person(s) performing the tree work must adhere to the most current of the following arboricultural industry tree care standards : 5. Best Management Practices, Tree Pruning. 2008. International Society of Arboriculture , PO Box 3129, Champaign , IL 61826-3129. 217- 355-9411 6. ANSI A300 Pruning Standards. 2008 Edition. Ibid . (Covers tree care methodology). 7. ANSI Z1 33.1 Safety Requirements for Arboricultural Operations . 2006 Edition. Ibid. (Covers safety). 8. Root collar & root collar excavation and examination: The root collar (junction between trunk and roots) is critical to whole-tree health and stability. A root collar excavation carefully uncovers this area (with hand digging tools , water or pressurized air). The area is then examined to assess its health and structural stability. Buttress roots may be traced outward from the trunk several feet. Decay assessment of t he large roots close to the trunk (buttress roots) involves additional testing such as drilling to extract interior wood with a regular drill, or the use of a resistance- recording drill to check for changes in wood density within the root ; as would be caused by decay or cavit ies. It is important to note that root decay often begins on the underside of roots, which is not detectable in a root collar excavation unless the entire c ircumference of the root is excavated and visible. Drill tests may detect such hidden decay. Note that it is not possible to uncover and evaluate the entire port ion of the root system that is responsible for whole-tree stability. Decayed roots t hat are inaccessible (e.g. underneath the trunk) can be degraded to the extent that the whole tree may fail even though uncovered and e xamined roots in accessible locations appear to be sound. 9. Root r o t d isease is caused by wet, poorly aerated soil cond itions . Deg radation of roots (root rot) and sometimes the lower trunk (crown rot) ensues on weakened , susceptible plant species not adapted to such a soi l environment. Opportunistic plant root pathogens (such as watermold fungi) are often the secondary cause of the problem . Root rot is a particular problem among drought tolerant plants that are not adapted to frequent irrigation during our normally rain-free months, such as many of our California native plants. The problem is often worsened in fine- I PO Bo x 3714 , Saratoga, CA 95070. 408-72 5-135 7. decah@pac bell .net. http://www .decah.com . I Arborist Repo rt f o r 16 5 30 Blac kb e rry Hill Rd .

Summer Dry: Our native oak species are adapted to our "summer dry" climate. When the soil in their root system is kept moist during our normally dry months, these oaks are predisposed to attack by fungal root rot pathogens that are usually present in our soils. Therefore it is important to keep irrigation as far from the tree trunk (preferably beyond the mature dripline) as possible. The best landscape treatment underneath native oaks is non-compacted soil covered with a 3 to 4-inch depth of oak wood, leaf and twig litter (the tree's natural litter). Keep this mulch 6 to 12 inches away from the root collar (junction of trunk and roots). An exception to the no summer water rule would be newly planted oaks (for the first 2 to 3 years after planting , until they are "established") and also during droughts that occur during the normal rainy season .
