FROM: Leslie Hopper, AICP, Project Planner APPROVED BY: Debbie Pedro, AICP, Planning Director That the Planning Commission: 1. Approve the requested tree removal and replacement, subject to the amended conditions of approval in Attachment 1. 2. Approve the requested use and storage of a 64 -foot tall construction crane if it can be determined that the benefits outweigh its visual impact. On December 8, 2005, the Planning Commission approved a new 19,280 -square -foot residence on an 8.03 -acre parcel located on the east side of Natoma Road, between Black Mountain and Altamont Roads. The average slope is 25.8%. Conservation and open space easements have been dedicated over 4.75 acres of the property. The building site is bounded on the north by a conservation easement, which slopes steeply down towards Deer Creek and includes open grasslands and densely forested areas. Surrounding properties are developed with single-family residences. To date, the applicants have prepared for construction by demolishing the existing house, removing and relocating some of the trees, rough -grading the building pad, and staging the construction operation. As directed by the Planning Commission, the applicants have tried to save two heritage oak trees in the conservation easement adjacent to the building site, but it has become apparent that removal will be necessary. The applicants are requesting authorization to remove and replace Trees #130 and #132. In addition, the applicants have requested authorization to use and store a 64 -foot tower crane on the property during construction. DISCUSSION Tree Removal and Replacement Trees #130 and #132 are located in the conservation easement on a ridge adjacent to the building site. They were originally slated for removal because the project arborist considered them to be in poor condition. At the Planning Commission hearing, neighbors who live across the canyon Plan.wg Cow. 29500 re Vida RW May 3, 2009 Page 2 of 12 on Foothill Lane voiced their concern that removal of the trees would leave the house exposed to their view. The project architect offered to save the trees if at all possible, and the Planning Commission approved the project with the condition that the applicants try to save the trees. (See Attachment 3 for Planning Commission minutes and Attachments 4 and 5 for original arborist reports.) Since that time, it has become apparent that efforts to save Trees #130 and #132 are not going to be successful. The applicant submitted a supplemental report prepared by a second arborist to provide additional information on the condition of the trees (Attachment 6). The report details the decay and structural problems of the two trees in question and recommends removal because of potential safety hazards. On Much 28, 2007 the Town's consulting arborist, Barrie Coate, visited the site and confirmed that removal of the two trees is necessary and prudent. In addition, he recommended removal of Tree #131 because its roots will be damaged in the process of grading (Attachment 7). The applicants have incorporated this recommendation in their plans; however, the grading has been minimized and they would like to save Tree #131 if possible. The applicants propose to replace Trees #130 and #132 with six 60 -inch -box oaks to be planted as shown on Sheet Ll -OT of the plans. The Town's arborist has reviewed the replacement proposal and concluded that it will provide adequate screening if the trees are well maintained until they are established. Amended condition #2 requires a tree maintenance deposit in the amount of $30,000 for three years to ensure survival of the new trees. Grading and Tree Protection The original, approved grading plan includes grading in the conservation easement. The intent was to remove fill soil around the heritage oaks and to restore the original grade. In the revised grading plan, the extent of grading in the conservation easement has been reduced so that grading is limited to the area around the trees to be removed. The revised limits of grading are consistent with Barrie Coate's recommendations. Mr. Coate also recommends specific maintenance procedures for Trees #133 though #137. Isis recommendations are incorporated in the amended conditions of approval. Grading Policy Exception In order to reduce the extent of grading in the conservation easement, a new retaining wall has been designed. The retaining wall is located at the foot of the ridge surrounding the building site. The retaining wall is seven feet at the highest point, and because it exceeds the maximum cut of four feet, an exception to the grading policy is required. The grading exception is justified because the retaining wall is necessary in order to protect the heritage oaks on the ridge adjacent to the building site. Use and Storage of Tower Crane Due to the need to move oversized building materials in an area with limited access, the applicant is requesting authorization to use and store a tower crane on site during construction. The crane would enable the contractors to make "heavy lifts" such as setting huge windows in place, moving steel and wood beams, stacking sheetrock and roof materials, relocating trees, and placing large mechanical equipment. The crane would be installed on a 24' x 24' pad. When Planning Commission 27500 to Vida Real May 3, 2007 Page 3 of 12 fully retracted, the crane would be approximately 18'W x 8'2"D x 64'H. Due to its size and height, the industrial tower crane would be visible from various locations off-site even when it is not in use. In comparison with mobile cranes with diesel engines, however, the tower crane would be quieter. In addition, traffic impacts and road damage would be minimized because the tower crane would be hauled on and off site just once. According to the applicants, the tower crane would remain in place until all major lifts are completed, which is estimated to be 14 to 18 months. To demonstrate the approximate height of the tower crane, the applicants installed a 64 -foot pipe on site. The photos below show the visibility of the of the demonstration pipe from neighbors' properties. To mitigate the visual impact of the tower crane, the applicant is offering to paint the crane a dark green (or whatever colors preferred by the neighbors) to blend in with the dense vegetation on the north slope of the property. Comments from neighbors regarding the tree removal and construction crane requests are included as Attachment 8. Tower crane when fully extended would be 18'W x 8'2"D x 64'H View from 27642 Vogue Court Planaincommissioo 27500 to VW Real May 3, 2007 Page 4 of 12 SUMMARY AND RECOMMENDATION Removal of the two heritage oaks is supported by three different arborists, all of whom have found the trees to be in poor condition and potential safety hazards. The trees would be replaced by six new oak trees, which would adequately screen the house from view. A tree maintenance deposit would ensure the survival of the trees. The extent of grading has been reduced and a new retaining wall added, and an exception to the grading policy for the retaining wall is justified in order to protect the five remaining heritage oaks adjacent to the building site. Recommendations of the Town's arborist for tree maintenance are incorporated in the amended conditions of approval. Staff recommends approval of the request to remove and replace Trees #130 and 132, subject to the amended conditions of approval. The amended conditions provide that Tree #131 may be removed if necessary. The 64' tall electric tower crane will have potential negative visual impacts to neighbors. However, it will be quieter than mobile cranes with diesel engines and will minimize traffic impacts and road damage. If the Planning Commission decides to approve the use and storage of the tower crane, the applicant should be required to paint the crane to blend in with the surrounding vegetation in order to minimize the visual impacts to neighbors.

ATTACHMENT Z TOWN OF LOS ALTOS HILLS December 8, 2005 Staff Report to the Planning Commission RE: SITE DEVELOPMENT PERMIT FOR A NEW RESIDENCE WITH PARTIAL BASEMENT, INDOOR SWIMMING POOL, AND THREE DETACHED ACCESSORY STRUCTURES; LANDS OF MALAVALLI; 27500 LA VIDA REAL; FILE #131-05-ZP- SD-GD. FROM: Leslie Hopper, Project Planner APPROVED BY: Carl Cahill, Planning Director e C. RECOMMENDATION That the Planning Commission: 1. Approve the requested Site Development Pennit, subject to the conditions of approval in Attachment 1. BACKGROUND The subject property is an 8.03 -acre parcel located on the east side of Natoma Road, between Black Mountain and Altamont Roads. The parcel was created in 2005 through the merger of two existing lots. There is one existing house on the western portion of the property; another house on the eastern portion was demolished prior to approval of the lot merger. There is an existing 3.50 -acre conservation easement on the north end of the property, which is steep and heavily wooded. Another 1.25 acres is proposed as new open space easement, making a total of 4.75 acres or 59% of the property under conservation/open space easements. A 20 -foot -wide hiking and equestrian easement runs along the north boundary of the property, on the south side of Deer Creek. Existing utility easements include a storm drain easement that varies from 20 feet to 30 feet in width through the western portion of the property; a 15 -foot PG&E easement and a 15 -foot PUE along a portion of the frontage on La Vida Real; and a 10 - foot Purissima Hills County Water District easement along the eastern and southeastern boundaries. Access to the property currently is provided by two driveways on La Vida Real. Surrounding properties are developed with single-family residences. CODE REQUIREMENTS As required by Section 10-2.301 of the Site Development Code, this application for a new residence has been forwarded to the Planning Commission for review and approval. Criteria for site development review include grading, drainage, building siting, pathways, landscape screening and outdoor lighting. Zoning Code review encompasses compliance with floor and development area limitations, height, setbacks, and parking requirements.

Most of the living area for the house is on the first floor (14, 088 square feet plus 382 square feet of double -counted high -ceiling areas). The second story (1,132 square feet) accounts for approximately 6.5 percent of the total floor area for the main residence. The first floor consists of an entry foyer flanked by a living room and dining room; a family room, kitchen, media room, library and garage in the south wing; and a north wing consisting of the master suite, guest rooms, indoor pool, exercise room, and laundry room clustered around an inner courtyard. The second story consists of a family room and telescope room above the main family room and kitchen below. The basement includes a theatre, wine cellar, and entertainment area, as well as two mechanical rooms, a computer room to house the equipment that controls the house and grounds, and a utility tunnel to provide service access to the infrastructure of the house. Three clusters of solar panels are located in the southeast comer of the site; one of the clusters is in a proposed open space easement. The square footage of the solar panels has not been included in the development area because the plans are still preliminary. (See discussion of solar panels on page 7.) Detached accessory structures include an office building (1,024 square feet), a garden pavilion (867 square feet), and a decorative landscape tower (519 square feet). The landscape plan Planning Commission 27500 La Vide RcM D.mb 8, 2005 Page 3 of 17 features several fountains and water features (2,358 square feet) as well as patios and walkways (10,999 square feet) and decks (891 square feet). Driveway and Parking Access to the property is provided by two new driveways on La Vida Real. The longer of the two driveways runs in an easterly direction, roughly parallel to the long leg of La Vida Real. Two small guardhouses flank the front gate, providing a grand entry to the estate. The second, shorter driveway begins at the cul de sac and provides direct access to the garage. The driveways and parking have been fully counted at 13,530 square feet. The Zoning Ordinance requires at least four on-site parking spaces, which have been provided in the six -car garage. Additional uncovered parking spaces are provided in the motorcourt in front of the garage. The motorcourt is located outside of the required setbacks. During parties and family gatherings, the longer driveway will provide additional on-site parking. Other than driveway accesses, no pavement is proposed within setbacks. The long driveway spans the existing drainage easement with a bridge and will not impact the drainage easement area. Architecture The architecture of the new residence is Santa Barbara Mission style, with a contemporary flare. The Malavalli residence has many characteristics that are typical of the Mission style, such as the following: • Smooth stucco siding • Low-pitched, red clay tile roofs • Roof parapets • Square towers • Arches above doors These traditional characteristics are blended with contemporary elements such as rounded, circular forms and areas of metal roofing, extensive windows and skylights, limestone banding, and stone cladding. Colors are traditional peachy -beige stucco walls and red clay tile roofing, with reddish -brown stone cladding and metal roofing, mahogany and sand colored limestone banding, and patina -green window frames. Height and Visibility At the highest point, the vertical plane height of the proposed new residence is 26 feet 5 inches measured from the bottom of the crawl space. The maximum overall height is 35 feet lowest to highest point of the new residence. The house will not be highly visible from the street because it is situated in the southeast quadrant of the property, well back from Natoma and La Vida Real. In addition, the building pad will be lowered as much as 8 feet in order to restore the natural grade by removing the existing fill that was used to raise the previous house. The house will be most visible from the back to Planning Commission 27500 La Vida Real Dremba 8, 2005 Page 4 of 17 neighbors who live across the canyon, but existing mature trees and dense vegetation will screen their view. The portion of the house located closest to a neighbor is the garage, which is 45 feet from the east property line. The detached office structure is closest to both Natoma and La Vida Real, and at one comer is 44 feet from the south property line. Lightine The roof plan (Sheet A4) shows 22 skylights, including one large skylight at the front entry, 14 skylights over the indoor pool, 6 over the guest suite, and one over the library. No lighting will be placed in the skylights. The large number of skylights is not likely to have an adverse impact on neighbors because of the relatively remote location of the house. Exterior lighting shall be limited to one fixture per exit with the exception of two fixtures at double -door exits. Lighting fixtures shall generally be shielded downlights. Lighting shall be low wattage, shall not encroach or reflect on adjacent properties, and the source of lighting should not be directly visible from off the site. Light fixture specifications and a detailed lighting plan shall be reviewed and approved by the Planning Department prior to acceptance of construction plans by the Building Department. Staff recommends that all outdoor lighting for the driveway and landscaping be forwarded to the Planning Commission for review along with the landscape screening plan as specified in Condition #5. Landscaping and Tree Removal The landscape master plan (Sheet L1.0) is not under review at this time and is included in the plan sets for information purposes only. Since more than half of the property will be protected by existing and proposed conservation/open space easements, most of the existing vegetation will not be affected by construction of the proposed residence. A tree inventory prepared by the project arborist lists 182 trees in the project area. The tree removal and relocation plan (Sheet LI.I) calls for removal of 24 trees, including three heritage oaks. All of the heritage oaks to be removed are in poor condition and could be hazardous. Another 29 trees, including six heritage oaks, will be relocated. In addition, several trees were previously dug up and boxed during the demolition of the existing house, and they are currently being maintained on the site for future relocation. The ultimate destination of the relocated trees and the replacement of the heritage oaks to be removed will be addressed in the landscape screening plan that is required under Condition #5. Condition #8 requires that the trees within the vicinity of the construction be fenced for protection and preservation. The Planning Commission will review a landscape screening and erosion control plan once the house is fumed. All planting required for screening or erosion control will be required to be planted prior to final inspection and occupancy of the new residence. Planing Commission 27500 U Vida Real D.bv 8, 2005 Page 5 of 17 Fencin As shown on the site plan (Sheet Al) existing chainlink fences will be removed. The existing split rail fence along the front of the property will be partially removed, leaving a portion along the intersection of Natoma and La Vida Real in place. New hedges will define the front entry and south side of the property along La Vida Real. A new 8-foot-high deer fence will wrap around the residence, following the perimeter of the existing and proposed conservation/open space easements. The purpose of the deer fence is to keep deer out of the landscaped areas. Attachment #4 shows the proposed design for the deer fence. In response to concems about potential impacts on deer and other wildlife that move through the 8-acre parcel, the applicants requested Live Oak Associates, an Ecological Consulting Firm, to study the issue. In a letter dated October 12, 2005 (Attachment #5), Michele Korpos concludes that the proposed fencing would not have a significant effect on wildlife movement in the immediate vicinity of the site or within the region. She explains that deer and other wildlife currently move through the property in a broad manner. Even though the proposed fencing will preclude wildlife from entering the site, wildlife will have access to approximately 4.8 acres or 60% of the site. The aerial photo attached to the letter shows the wildlife movement corridors on the project area. Grading and Tree Protection The Engineering Department has reviewed the plans and recommended the conditions of approval incorporated in Attachment 1. All proposed grading on the site conforms to the Town's grading policy. Estimated earthwork quantities for the project include 9,700 cubic yards of cut and 780 cubic yards of fill. The remaining 8,920 cubic yards of excavated material will be exported off site. The proposed residence will be located approximately in the same location as the demolished house. In that location, an elevated building pad was constructed approximately 30 years ago to artificially raise the level of the house. As documented in the soils report for the project, the old building pad contains approximately 1.5 to 9 feet of unconsolidated fill. The intent is to restore the site to its natural grade by removing the fill, thus providing a more stable foundation for the new residence. Some of the fill associated with the demolished residence extends into the existing conservation easement area north of the proposed residence, where six heritage oaks could be adversely impacted by the removal of soil. Two of these trees (#130 and #132) are marked for removal on Sheet Ll.l because they me in poor condition. However, the project architect would like to save the trees if possible, and the Town arborist supports this effort, especially with regard to tree #130. The grading plan (Sheet C3) shows the area where removal of fill soil in the conservation easement would occur. Tree preservation notes on the grading plan stipulate that no heavy equipment will be used and all digging will be by hand. In addition, all digging will be done under the supervision of the project arborist. These tree protection measures have been reviewed Planning Commission Ikcemb. 8, 2005 Page 6 of 17 by the Town's consulting arborist, Barrie Coate, who has determined that they may not be sufficient to protect the trees. Mr. Coate believes that after all these years, tree roots are likely to be present in the fill and that any kind of grading or removal of the soil, either by hand or by equipment, will damage the roots of these heritage trees. The Town's consulting arborist recommendations are attached as Attachment V. In Item #4 Mr. Coate recommends that a test trench be cut with an Airspade, which will not damage any roots if they are encountered. If a significant quantity of absorbing roots are found between elevations 568 and 572, no grading should be permitted. This recommendation is incorporated in the tree protection measures included in Condition #1. In addition, chainlink fencing will be required to separate the area where no heavy equipment is allowed and digging must be done by hand only. The trenching and hand digging, if any, will be supervised by the Town's consulting arborist. Drainage Natural drainage at the site is characterized by sheetflow directed away from the north -trending ridge, where it is intercepted by Deer Creek to the north and by a north -trending gully to the west. Proposed drainage improvements for the new residence involve the collection of stormwater through a system of area drains, catch basins, and pipes that carry the water around and away from the new residence. A retention/dissipator structure southwest of the new residence will collect and dissipate the drainage, which will be discharged at a point north of the driveway and near the drainage easement. The final drainage will be reviewed by the Engineering Department prior to final inspection and occupancy of the residence. Sanitary Sewer Sheet C4 shows the proposed connection to an existing sanitary sewer line at the intersection of Altamont, Natoma and Tripoli Court. The sewer will be extended along Natoma and connected to a lateral in the southwest corner of the property. A sump pump and basin will be located behind the 30 -foot setback line along Natoma. A connection fee will be charged for hook-up to the existing sewer line, which is in the Los Altos Basin. Energy Efficiency In a letter dated October 12, 2005 (Attachment #8) the project architect describes the energy saving features of the new residence, such as the following: • Solar panels to generate a portion of the power used for house and grounds • Computerized control of heating, cooling, lighting, and other mechanical systems • Energy Star certified appliances, mechanical units and pool equipment • Additional insulation in exterior walls • Insulated "low E" glazing on windows and exterior doors • Skylights to bring in natural daylight and provide ventilation in the pool area In addition, the project will use recycled materials as much as possible, and when the existing house is demolished, materials will be salvaged and reused. December 8, 2005 Page 7 of 17 Water use will be minimized through the use of tankless water heaters with recirculating pumps, low -flow toilets, and a computer -controlled irrigation system. Solar Panels As noted previously, the plans show three clusters of solar panels located in the southeast comer of the site. One of the proposed clusters is located an open space easement, which was not considered by the Open Space Committee during its review of the project. The square footage of the solar panels has not been included in the development area because the plans are preliminary only. As stated in the information booklet provided in Attachment 16, the architect is currently researching the use and integration of the photovoltaic panels. Normally a separate permit for installation of solar panels is required, and details will be reviewed when that application is submitted. Based on the preliminary plans, approximately 3,000 square feet will be covered by solar panels. Town policy exempts the fust 500 square feet in order to encourage the production of solar energy. The addition of 2,500 square feet for solar panels will push the project over the maximum development area. Fire Department Review The Santa Clara County Fire Department reviewed the plans for the project and determined that prior to issuance of a building permit the driveway must be modified to provide adequate turning radius for a fire truck. In addition, a utility plan must be submitted showing all required hydrants and hose valves. Fire Department requirements are incorporated in the conditions of approval (Attachment #1). Oven Space Committee Review Bounded by an unnamed tributary of Deer Creek on the north, the 8.03 -acre parcel includes a natural swale that is protected by a drainage easement. It also includes areas of steep slope with forested areas and open grassland that serve as habitat for deer and other wildlife. A portion of the property (mainly the swale and riparian area along Deer Creek) is designated in the General Plan as open space conservation area. Most of this area is included in the existing 3.5 -acre conservation easement. In order to protect the remaining areas of steep slope and as much of the natural swale as possible, another 1.25 acres are included in proposed open space easements. The proposed open space easements are contiguous to the existing conservation easement. Together the combined easements total 4.75 acres, comprising 59% of the site, and they wrap around three sides of the new residence and grounds. The Open Space Committee has visited the site to view the proposed open space easements and recommends approval. The solar panels were added after the plans were reviewed by the Open Space Committee, and the committee has not considered the proposed placement of solar panels in the open space easement. De.ber 8,2005 Page 8 of 17 Pathway Committee Review The Master Pathway Plan shows a path along an existing 20 -foot hiking and equestrian easement on the south side of Deer Creek. During the Master Plan adoption process last March, the Planning Commission recommended that this segment of the pathway plan be removed from the plan because the terrain is steep and heavily wooded. The City Council decided to leave it in because there is an existing easement and construction of the path could be determined at a later date. The Pathway Committee reviewed the project plans and visited the site on several different occasions. As reflected in the attached minutes (Attachment #11) the committee recommended construction of a native path. The best route for the path would not necessarily be located within the existing easement, and the committee recommended that the easement be adjusted as necessary to be consistent with the path. The applicants do not consider construction of the path to be appropriate, and they have expressed their concems in the attached letter (Attachment #12) which includes a report by Michele Korpos of Live Oak Associates. In addition to potential environmental and biological impacts, the applicants raise safety issues, noting that Natoma is particularly narrow and steep in that area, and there is limited visibility along that stretch of road. That opinion is shared by Brian Macnick, whose property borders the Malavalli's property on the north side. In a letter dated November 7, 2005 (Attachment #13), Dr. Macnick expresses his concern due to practical, environmental and safety reasons. The applicants request that they be allowed to pay pathway fees in lieu of constructing the path. Having hiked through the area, planning and engineering staff agree that the path would be difficult to construct and maintain. The Planning Commission has two options regarding the path 1. Require construction of the path in or near the existing easement along the south side of Deer Creek. 2. Require payment of pathway fees at the standard rate of $46.00 per linear foot of average lot. A pathway condition will be added to Attachment #1 to reflect the option selected by the Planning Commission. Environmental Design Committee Review The Environmental Design Committee recommended that the largest oaks slated for removal be saved and relocated instead if possible. As shown on the tree removal and relocation plan (Sheet L1.1) Trees 4124 and 4180 will be relocated. Both trees are sizable oaks with 28 -inch and 30 - inch diameters, respectively. The committee also commented on the extensive number of skylights and the use of metal roofing. As noted on the plans, no lighting will be placed in skylight wells. The metal roofing will not be copper but will be a non -reflective material painted to match the red clay tile roof. Planning Commission Ckcemhr 8, 2005 Page 9 of 17 The plans originally included maids quarters and a bell tower but they have since been omitted or revised. The decorative landscape tower no longer includes a bell so that neighbors will not be impacted by the noise. Neighbor Comments A letter of support has been received from Sandy Laws -Miller at 12821 La Vida Real (see Attachment #15). The Laws -Millers are the closest neighbors, and their only concern is the proposed path along Deer Creek. Environmental Review The project is categorically exempt under CEQA Guidelines Section 15303 (a) construction of single-family residences. SUMMARY The proposed project is below the allowable floor and development area for the property. The project is in compliance with the requirements of the Zoning and Site Development Codes. The proposed grading in the conservation easement is acceptable provided the recommended tree protection measures are required. The proposed open space easements have been recommended for approval by the Open Space Committee. The project will be energy efficient, will minimize water use, and will incorporate recycled building materials as much as possible. Pathway options include construction of a path in or near the existing easement as recommended by the Pathway Committee, or payment of pathway fees if construction is not practical. Although neighbors have voiced concerns about construction of the path, they have no objections to the project in general. Staff recommends approval of the project subject to the conditions of approval in Attachment 1. Commission n .bcr 8, 2005 Page 10 of 17 ATTACHMENTS 1. Recommended conditions of approval 2.

Los Altos Hills, CA 94022 39039 Paseo Padre Parkway, Suite 201 Fremont, CA 94538 ATTACHMENT 3 Minutes of a Regular Meeting, Approved 1/19/06 Town of Los Altos Hills PLANNING COMMISSION THURSDAY, DECEMBER 8,2005,7:00 p.m. Council Chambers 26379 Fremont Road cc: Cassettes (2) #1-06 ROLL CALL AND PLEDGE OF ALLEGIANCE The regular meeting of the Planning Commission was called to order at 7:00 p.m. in the Council Chambers at Town Hall, Present: Chairman Cottrell, Commissioners Carey, Kems, Collins & Clow Staff. Carl Cahill, Planning Director; Leslie Hopper, Project Planner; Debbie Pedro, Senior Planner; Brian Froelich; Assistant Planner; Lani Smith, Planning Secretary 2. PRESENTATIONS FROM THE FLOOR -none 3. PUBLIC HEARINGS 3.1 LANDS OF MALAVALLI, 27500 La Vida Real (131-05-ZP-SD- GD); A request for a Site Development Permit for a 17,389 square foot two-story new residence with a 5,752 square foot basement and a new driveway, a 1,024 square foot detached accessory building, and an 867 square foot detached garden pavilion (maximum structure height 27 feet). Parcel size: 8 acres including 3.54 acres in conservationlopen space easements (staff -Leslie Hopper). Planner Hopper introduced this item by reviewing the staff report, in particular, the following items: description of the project on an 8.03 acre site; background of the project including an aerial photo of the site; access to the property provided by two new driveways both of which have been counted 100% in development area; the Santa Barbara Mission style architecture; the height and visibility of the project and the lowering of the building pad as much as 8 feet in order to restore the natural grade by removing the existing fill that was used to raise the previous house; the visibility of the back of the house to the neighbors who live across the canyon; lighting which includes 22 skylights; landscape and a tree inventory including trees proposed to be removed; grading and tree protection; and connection to an existing sanitary sewer line. She further discussed the existing conservation easements (3.50 acres) on the property as well as the two new proposed open space easements (1.25 acres) all totaling 59% of the property. The Pathway Committee recommended the construction of a native path. The best route for the path would not necessarily be located within the existing easement so the Committee recommended that the easement be adjusted as necessary to be consistent with Planning Commission Minutes Approved 1/19/06 December 8, 2005 Page 2 the path. However, the applicants do not consider construction of the path to be appropriate per a report from Michele Korpos of Live Oak Associates. They are requesting that they be allowed to pay pathway fees in lieu of constructing the path. Staff, having hiked through the area, agreed that the path would be difficult to construct and maintain. She continued stating that the site plan calls for three clusters of solar panels located in the southeast comer of the site with one of the clusters in a proposed open space easement. Altogether, the solar panels would comprise approximately 3,000 square feet. This total has not been included in the development area. At this point, the solar panels are conceptual only and if they are to be installed in the proposed location it would push the project over the maximum development area. This needs to be addressed. Another item to be addressed is while restoring the natural grade by removing the existing fill there is a concern with the six (6) Heritage oaks with possible roots extending into the fill. In order to protect the oaks, they have proposed some tree protection measures which have been incorporated into the conditions of approval recommended by the Town consulting arborist (COA #1). Planner Hopper concluded her presentation noting that there was a model of the project site available for review. Commissioner Carey clarified that during the time of reviewing the Master Path Map, the Planning Commission recommended the removal of this pathway with the City Council recommending the path to be kept. Discussion ensued regarding how a driveway was counted toward development area. Planning Director Cahill indicated that the first 100 feet from the required garage is counted. Anything beyond the first 100 feet of the required driveway is not counted. In the case where someone constructs accessory paving and driveway that is more for personal aesthetic reasons, it is counted the same as a patio or any sort of hardscape surface. Commissioner Kerns questioned the deer fence plan which appears to be for reference and will return with the landscape screening plan. Planner Hopper indicated that the deer fencing is also shown on the site plan and will be a part of this proposal tonight. For clarification, she indicated the location of the proposed deer fencing noting the areas of fence within the conservation easement which drops in height to meet the current fence ordinance. OPENED PUBLIC HEARING Kartik Patel, project architect, provided a brief history of the project. He felt that everyone would be proud of this project, not only the applicants but also the community. He discussed green architecture, architecture that is sensitive to the environment taking into account the topography, the neighbors and the surrounding neighborhood architecture. The project team was present which included the landscape architect, the environmental consultants, team arborist and also a representative from Valley Crest who will be taking cue of all of the trees that have been removed when the first home was demolished and have been cared for the past year. Also present was their solar consultant as they want to make this house as efficient as possible and try to conserve energy. With the aid of a visual presentation and a full scale model of the site, Mr. Patel discussed the following: the recent lot merger; the existing and proposed conservation areas which will total close to 60% of the property; the long narrow lot Planning Commission Minutes Approved 1/19/06 December 8, 2005 Page 3 with a house placement on a flat area; the long driveway which addresses the estate type home with a drop off point at the front door of the house; the long driveway to accommodate any traffic on the site; the request for some credit for the driveway to accommodate the proposed solar panels; several gardens on the site; the Santa Barbara Mission style house with a central courtyard in the back; the proposed color palette; and the landscape design and water features. He understood that there were two neighbors who were concerned with the view of the tower element indicating the distances from each neighbor. In conclusion, Mr. Patel stated that the architecture of the house was inspired by the Santa Barbara Mission style. They felt strongly that given the geographic location, this style best fits the area. The projects will implement green architecture and energy conservation. Mr. Patel indicated that the representative from Valley Crest will be discussing the removal and transplanting of specific oak trees. Regarding the conditions of approval, they would like the Commission to review four items: (1) request to remove/clew poison oak from the current and proposed conservation easements; (2) development credit for the long driveway which will be used for the solar panels; (3) grading proposed around the oak trees asking if they would be allowed to use very light power equipment to move the dirt in the presents of an arborist. If there is evidence of significant roots, they would not grade in that area. (4) opposed to the construction of a pathway. He felt there was a major safety issue with the path as there is no good termination of the pathway once you reach Natoma Road. Natoma Road is a very steep, windy road with a blind comer at that point. This is a very dangerous area and not a good termination of the pathway. Also, it is an environmentally sensitive area needing two bridges involving the Army Corp of Engineers and the Department of Fish and Game. Also, they have not found anyone in the neighborhood who is requesting them to build the pathway. Commissioner Clow asked if the solar arrays were visible to any neighbors. Mr. Patel responded not to his understanding. The way they could find out is to erect story poles. In answering a question, he noted that the natural foot paths leading into the new conservation would be allowed as it meets the conservation easement goals. Mr. Malavalli, in discussing his dream house will make sure it is a quality house retaining the nature habitat of the area. Los Altos Hills has been their home for the last 10 yews indicating it took that long to find the ideal area for their house. He does want to keep his neighbors happy. He appreciates Los Altos Hills' environmental restrictions as they want to maintain the natural environment. Dale with Valley Crest stated the company has been moving trees for the last 50 years in California. They have already moved many trees on site and have maintained them for the last year. They are all doing great. There is thought of moving two additional trees on the site which we larger than the ones already moved. It should be a successful move (the company is in the high 90% success rate). Cue of a tree after it is moved is important so they maintain the trees after they are moved which could last for years. Planning Commission Minutes Approved 1/19/06 December 8, 2005 Page 4 Mr. Patel would like to try to save the existing oak trees #130 and #132 slotted for removal. Even though the approval package shows them to be eliminated they have requested that they try to save them and maintain them throughout construction and review their conditions at the end of the construction period. David Bulfer, Lucem Lane, looks down on the two properties that have been merged and has had the pleasure of meeting the applicants who care about the environment. He felt the improvements will make the site more rural. He walks every morning with his wife and he felt the proposed path was too dangerous to use. His biggest concern was the process of the construction and felt the applicants will consider the neighbors in the entire process. He voiced support of the project De Gheest, 12133 Foothill Lane, property located across the canyon. She provided a photo of the property site as viewed from her kitchen. She explained that she will not only see the top of the roof but also a part of the walls. There will be a significant view of this property from her house as well as being an eye sore with the proposed removal of trees. She asked that if the two oak trees are removed they be replaced three to one to provide privacy to the people across the canyon. She noted that they asked for the same thing when the two lots were merged. She would also hope that the construction site would not be too visible by using a dark color fence instead of an orange fence. She also noted that the tower was very visible and one of the trees behind it is slated to be removed. Regarding the proposed solar panels, she requested that they erect orange poles prior to approval to view the full impact. Brian Macknick, 27608 Vogue Court, resident for over 22 years, spoke against the off road pathway through Deer Creek wildlife corridor as proposed due to environmental and ecological issues. He referred to the letter from Live Oak Associates regarding their findings and the value of preserving this wildlife corridor in its natural state. He also supports the efforts of the wildlife survey recently mailed out by the Town. Maintaining natural corridors will keep animals healthy and wild and minimize contact with humans allowing them to continue living in as natural state as possible. He further discussed safety, ingress and egress on this pathway which includes crossing over Natoma Road with a very narrow and tight turning road with no shoulder. He felt it was a foreseeable event that horses or people could be injured by having this path exit right onto and then cross over Natoma Road to the other path on a blind curve as presently proposed The Town's Master Pathway Plan was just reviewed last March when the Planning Commission recommendation regarding B3.22 or Deer Creek was not to retain MPP due to erosion issues on steep ravines and redundancy to existing off road paths from Black Mountain Road. John Spar, 12121 Foothill Lane, as a new owner, he has not had time to digest the proposed application. Mark Vernon, 12119 Foothill Lane, echoed comments made by resident at 12133 Foothill Lane as he was very concerned with the removal of trees which currently helps screen the site. He felt any new plantings would not screen anything unless they were of significant height and span like the trees presently on site. He felt he needed more information regarding the Planning Commission Minutes Approved 1/19/06 December 8, 2005 Page 5 trees slated to be removed. He stated he was not strong on the pathway issue. The letter from the Town's consulting arborist had requested more information regarding the trees to be removed. Ginger Summit, 13310 Lennox Way, Chairperson of the Pathway Committee, spoke to the proposed path which is potentially a very beautiful path. She felt it was important to maintain the existing paths and increase them whenever possible. The easement exists, only requiring construction. When the Committee walked the path there was some question as to where the boundaries actually exist. She believed that the applicants were going to have the area re- surveyed to clarify the boundaries. The proposed native easement is for 5 feet however, it could be less. She did not feel it was infringing on anyone's privacy. She further discussed the flexibility where the path would exit onto Natoma Road. Discussion ensued regarding culverts and/or retaining walls made of natural material (not concrete). It would be the Committee's preference not to have the path cross the creek but to stay on one side of the creek by modifying the easements appropriately so they would not have to construct bridges. The Committee would work with the property owners and their landscape person to make it as financially reasonable as possible. Dot Schreiner, Saddle Mountain Drive, quoted from the General Plan Pathway Element adopted in 1996 stating that "the pathways system serves three basic and important function; circulation, recreation, and preservation of the open character of the Town". "Off-road paths, which connect to roadside paths or open space lands, are generally located on dedicated easements on private property (usually along property lines), through public lands, or through privately owned conservation/open space easements". She further referred to B3, off-road paths. She felt this was a very important path in Town and has been on the Master Pathway Plan forever. She hoped that the Commission would honor the commitment of all the work that has been done in the past and the decision by the Town Council that this is a path that should be in this Town. Bob Stutz, Elena Road, walked the area in the 70's. He noted that if you come in contact with poison oak you use a Borax solution for relief. Steve Kellenberger, Vogue Court, supports the pathway system but not in this case as the grade and terrain me steep. The existing easement 20 feet from the center line of the creek would put the potential path mid -way up the grade fall line. There is a severe problem with erosion with any path that is built. Privacy is also an issue. He did not feel the pathway would be used as much as those pathways already existing. Scott Vanderlip, Fremont Pines Lane, supported the path. If a bridge is built, it could service another trail connecting to Taaffe. Denise Williams, Corbetta Lane, voiced support of the path Planning Commission Minutes Approved 1/19/06 December 8, 2005 Page 6 Roger Spreen, Chairman of the Open Space Committee, was very thankful for the conservation easements on the site, thanking staff and the applicants. In general, the committee would prefer to leave an open space easement in a natural state but it is not against the terms of an open space easement to remove poison oak. Kristin Emery, 12121 Foothill Lane, new owner, asked that the trees be preserved for screening purposes. David Bulfur, Lucem Lane, asked that trees #130, 132, 147 and 150 not be removed. Resident at 12845 La Vida Real, has small children and takes them onto Natoma Road everyday. It is his experience that it is very dangerous on that road. Unlike other neighbors, if some trees are removed it will improve the views he use to enjoy. Mr. Patel addressed comments regarding the trees scheduled to be removed: #150, a large eucalyptus; #147, 24" box oak tree to be relocated; #130 and #132 deemed structurally unstable. These are the two trees that they would like to save. Most of the trees proposed are going to be significant in size (15'x1 5'x10' in height), approximately 40 specimens. Commissioner Kerns questioned tree #147 w it provides screening of the bell tower which some residents voiced concerns. He asked Mr. Patel if he was willing to keep #147 in its current location along with #130 and #132. Mr. Patel responded yes. He indicated that he had walked the site with both Bob Stutz and Les Eamest. He stated that the property line is the center line of the creek. They staked this property several times, even the 20 foot easement. It is clear that when you take the 20 feet to the center line of the creek it is impossible to build. It is clear that they will need to cross the creek in two places; bridges will need to be built. They have never been under the impression that the path would be a 2 foot trail (native path). They have been told that the Committee had the authority to go beyond the 20 foot easement but there seems to be an issue regarding the removal of poison oak within the conservation easement. There is a real conflict of basic principles of what they are trying to achieve as a community. CLOSED PUBLIC HEARING Disclosures: Chairman Cottrell, Commissioners Carey and Collins walked the site in the company of the architect. Commissioner Clow walked the site with the architect and met with two of the neighbors. Commissioner Kerns walked the site and spoke to the architect by phone. Commissioner Clow suggested separating the application and the pathway. He felt the project is beautiful. The applicants we spending approximately one million dollars moving and preserving trees which is an outstanding contribution to the community. They have a real commitment to energy efficiency with the plans for solar power. He would like to find a way to support the proposed solar power perhaps with an exception in development area. Planner Cabill suggested only counting the actual footprint of the free standing solar. Commissioner Planning Commission Minutes Approved 1/19/06 December 9, 2005 Page 7 Clow could support this suggestion. He did not feel that they would find oak tree roots in the fill area and he could support removing that fill using light machinery. The architect had indicated that tree #147 would be moved but he felt it was not intended to be removed. The residents across the valley have a real interest in keeping a tree that would shield the house from their views. He would support retaining tree #147. He does not support retaining the Eucalyptus tree. He would recommend approval of the project. Regarding the pathway, he felt that they needed to honor the process. They went through a process as a Town to create a path map. As a Commissioner he had voted against this path segment as did the other Commissioners. However, the Council voted for it. He would honor a type of path appropriate for that valley. The Gintzen path in Byrne Preserve is a good example of an appropriate path (more like a two foot wide path). Any retaining walls would be 2'x 1'0 with stake into the hillside (no concrete retaining walls). There may be a need for bridges. The idea of having a path going into the conservation easement going away from the creek where needed to make a comfortable path makes sense. He would not expect any large trees to be cut down to create this path. Commissioner Collins discussed the four points presented by Mr. Patel: (1) poison oak removal in the conservation easement (supports); (2) credit for the driveway (does not support); (3) grading, agrees to save tree #147. She thought he had it in his heart to save the other two trees. They should be able to use light equipment if they do not discover roots. (4) Pathway, the pathway was already decided upon during the Master Pathway process (honor the map). Commissioner Kerns voiced support of the application with the use of the energy efficiency (solar panels throughout the project). He also agreed that he would rather not give credit for the driveway but instead allow the construction of the solar panels. He felt trees #130, 132 & 147 should remain and shown as not being removed, making every effort to keep those trees. He also supports the use of light machinery if they determine that the roots are not substantial in that area as well as the poison oak removal. He has not been a strong advocate of off-road pathways in areas where the neighbors do not support them. He felt there was a parallel pathway on Black Mountain that essentially connects the same areas. He was very concerned with the wildlife corridor and when they had this discussion at the Planning Commission during the review of the Master Path Map it was unanimous that they did not support this pathway. Commissioner Carey supported the removal of poison oak from the conservation easement. He would allow more credit for the driveway as it is a required element for the house giving, credit for the fust 100 feet and the like credit for the smaller driveway, using the available development area for the solar panels only. Regarding the grading around the oak trees, he would allow grading to be done in that area with light machinery whether or not there me roots in the fill. Grading in the area is preferable to retaining walls. He supports the retention of trees #130, 132 and 147 rather than removing those trees. Regarding the pathway, he agreed with Commissioners Clow and Collins by supporting the Master Pathway Plan. Planning Commission Minutes Approved 1/19/06 December 8, 2005 Page 8 Chairman Cottrell stated to all of the neighbors present how fortunate they were to have an applicant who cares about them and the environment and who has brought in a plan of this kind. He supports the removal of poison oak, using light equipment for the grading and trying to save trees #130, 132 and 147 and any others except the Eucalyptus tree. He also voted against the pathway last March but they do need to support the City Council. The pathway should be a nature type pathway. If there are issues when it comes time to lay it out, he suggested going back to the Pathway Committee so you end up with a path that has some common sense to it. He also supports the solar panels. MOTION SECONDED AND PASSED: Motion by Commissioner Clow and seconded by Commissioner Carey recommending that the pathway be built with the guidance that it be more of a 2 foot wide pathway rather than a 5 foot pathway something similar to the Gintzon trail in Byrne Preserve. Concrete retaining walls or large tree removal is not recommended. Two bridges may be necessary. At the applicant's discretion, they could widen the pathway easement to allow the pathway to go further away from the property line to better stay with the terrain. The actual layout of the pathway is at the applicant's discretion (construct a native path) with any needed assistance from the Pathway Committee, Lands of Malavalli, 27500 La Vida Real. AYES: Chairman Cottrell, Commissioners Collins, Carey & Clow NOES: Commissioner Kerns MOTION SECONDED AND PASSED: Motion by Commissioner Clow and seconded by Commission Kerns to approve the Site Development Permit for a new residence with partial basement, indoor swimming pool, and three detached accessory structures, Lands of Malavalli, 27500 La Vida Real, with the following additions/changes to the conditions of approval: add to the conservation easement description that the applicants are allowed to remove poison oak; exempt the solar panels from development area except for the footing area; allow light equipment for the removal of the fill; the applicants will try to save trees #130 & 132; tree #147 shall not be removed; tree #150 (Eucalyptus tree) can be removed; remove. Delete#1 (5); change #1 (6) as follows: Grading will be allowed to occur by hand, with the use of shovels, hand mattocks, hand trowels and light equipment.

Coate Consulting Arborist November 14'", 2005 Job# 10-05-212 ATTACHMENT 5 REVIEW OF THE ARBORJSTS hePORT FOR THE MALAVALLI RESIDENCE Assignment On November 10's, 2005, I received a copy of a report titled "Tree Protection Specifications" Malavalli Residence, La Vida Real, Los Altos Hills as prepared by Deborah Ellis, Consulting Arborist It was accompanied by a full size and reduced sized map. The full size plan includes topographical lines. I've been asked to review this report. It is my understanding that you are particularly interested in grading near trees # 130-138, native Oaks. Summary Pages 1-4 With the exception of Item 6 of the 9 items on these pages, the information and instruction offered are general in nature and not that specific. That is not necessarily a problem unless you need more information about a specific tree than that provided in the data accumulation charts which accompany pages 14. As example, an explanation seems appropriate for the information on those charts for trees 478 and 81. Why is there an SOD threat? Or tree 4123, a large, well formed Aleppo Pine is to be removed. I would want more Z3 i S explanation for this decision and even some pictures explaining the claimed poor conditions. � Pf' Kin other words, a textual part of the report should be included that provides enough information about trees to be removed and reasons for removal, and specific tree preservation details for trees which are to be saved. Different trees need different preservation procedures, depending upon species, tolerance of root disturbance, the health of the specimens, and its proximity to proposed grading or construction, so general preservation guidelines do not provide adequate directions for preservation of individual trees. Grading in the conservation easement: Assuming that fill soil has been added to the site, including the area beneath the canopies of Oaks #130-136, as Mrs. Ellis states, and that fill was added more than 2 years ago, one would assume that absorbing roots have gown up into this fill, making the trees dependant upon that fill and these roots for a significant part of their moisture and nutrient supply. Mrs. Ellis states (Item 6, p2) that the grading in the conservation easement "shall be done by hand and under the direct supervision of the Project Consulting Arborist." PREPARED BY BARRIE D. COATE, CONSULTING ARBORIST REVIEW OF THE ARBORISTS REPORT FOR THE MALAVALLI RESIDENCE In contradiction, however, in a single page note to you on 10/28/05 she states (Item 3) "soil shall be removed only around the trunk of trees. Other areas or old fill soil or natural grade shall remain undisturbed." The plan from DeBolt Engineering dated 11/7/05 shows grading in much of the area beneath the southern part of the canopies of these trees down to elevation 572 (titled Limits of Grading) which would result in removal of four feet of soil in areas beneath some tree canopies and imply removal of tree 4136, a 31.5" Oak. If the permission to make grading cuts beneath the canopy of these trees hinges on presence (or lack of) roots in the soil to be removed, an Airspade® could be used to cut a 2' Wide trench to the desired depth to determine finally whether significant quantities and/or size of roots are indeed present. This device removes soil without harming the encountered roots. Without evidence that no significant quantity of absorbing roots of 2" diameter or larger roots are present in the soil between elevation 568 and 572, 1 suggest that this grading not be allowed. - - Respectfully submitted, Barrie D.

Inspection Date: 2/6/2007 Inspector: Ray Momeau, ISACertitied Arborin#wC-0132A ------- — ------------- ------ ------------------------------------- Tree #130 & #132: Supplemental Report 1.0 Assignment, Introduction, & Summary 1.1 Assignment: Inspect and report on the condition/status of two coast live oak trees (Quercus agrifolia) [#130, #1321 growing at the edge of a conservation easement at the Malavalli Residence construction project on La Vida Real in Los Altos Hills. 1.2 Introduction: By way of background, pre -construction arborist inspections and reports have been prepared by another Consulting Arborist, Deborah Ellis. Early on in this project, the owners realized the importance of their site's trees and established a policy to preserve as many as possible. Evidence that they are carefully following a well -conceived plan shows in several ways, including: • the preparation of a very professional tree survey and arborist report (dated December 12, 2005), • follow-up communications with the Project Arborist [memos, "Tree Notes", "Poison Oak Management"– to mention a few], • implementing tree preservation measures (including tree protection fencing), • preparing for transplanting several specimens on-site (boxed and held in watchful storage off to the side). Ms. Ellis's first report identified the two subject oak trees as candidates for removal based on the presence of extensive decay and proximity to the proposed construction rendering them high risk for failure. The owners decided to try to save them, if possible. Therefore, a wait-and-see attitude has been likes and they were not removed during the prior demolition stage. Ray Morneau, Arborist I5ACertifled Arborist#WE-0132A 650.964.7664 1.3 Summary: This February 6, 2007 follow-up inspection finds the area of proposed construction now clearly identified. This arborist now sees that Ms. Ellis's observations of extensive compromised tissue in both oaks are very correct. She even called out these two oaks with special photographs on pages 16 and 17 of her 12/12/05 report, as if to emphasize the importance of their defects. The construction staking shows how close actual construction impacts must come, which will be an additional factor in root loss (especially for #130). Also, in the event of failure of either specimen, the risk of injury and/or damage is very high because they are located so close to a high use areas. Scheduling of removal before continuing with this project is the most prudent conclusion. 2.0 Observations & Discussion: 2.1 Locations: northeast of the new residence, just inside of a conservation easement. 2.2 Size Table: #130 #132 39" 39" diameter at 4.5 feet 30' 35' height 20' 25' average foliage crown radius 40% oor 25% (Very Poor overall condition ratio 2.3 The foliage crowns are lop -sided as they compete(d) for the same space from adjacent trees. 2.4 Both crowns are reasonably green (especially #130), carrying on photosynthesis. So, they are alive. But, upon close observation, one sees indications of decline (especially #132. The leaves are smaller than normal. The annual twig growth (tip extension) has been shortening over the most recent five years. 2.5 Many old wounds have cavities started there, with a substantial amount of decayed tissue. This pair of photographs (right) show areas of extensive decay -compromised tissue on oak #130. February 18, 2007 Oak #130 8 #132 Status Report: Malavalli Residence, LAH. Page #2 of 6. 4041161 Ray Mornatu, Arborist ISA Certified Arbnrist#WE-0132A 650.964.7664 These three photographs (below) show oak #130's "see-through" defect from two sides, plus an 18 -inch -diameter lateral branch with decay weakening the already - poor -attachment. The supporting structure of both of these oaks is severely compromised, which presents a problem of a high risk of failure of large portions of these trees. [Large pieces meaning trunks and/or major limbs.] 2.6 Fill soil from construction of the previous home has been a problem for these oak trees — suffocating the roots and promoting root -rotting fungi in the critical areas of the root flares (where the trunk changes from stem tissue to scaffold roots). A root crown excavation would expose the original root flares and find extensive compromised cambium and sapwood from collar rot (Phyrophthora) and oak root fungus (Arrai/lario) connecting up with the columns of decay visible in the above -ground trunks. Sounding the trunk tissue at ground level found disintegrating areas, which "sounded hollow" because the cambial tissue just under the bark had been destroyed by fungi. 2.7 As shown by the construction staking, more roots will be lost to excavation work which must come closer to the trees than it is now — especially 9130. 2.8 in his 11/17/2000, Hazard Tree Assessment Workshop, Hayes presented guidelines and directions for making such an analysis as discussed by Smiley and other arboricultural researchers/writers (Coder, 1996; Matheny & Clark, 1994; Mattheck & Brelcer, 1994; Minnesota DNR & USDA Forest Service, 1996). NOTES: A "Hazard Tree" is defined as a tree with a significant defect of such a magnitude February 18, 2007 Oak #130 & #132 Status Report: Malavalli Residence, LAH. Page #3 of 6. Ray Morneau, Arborist ISACertified Arboristt#WE- 132A 650.964.7664 that a substantial risk of failure exists in the presence of a target. A "target" is someone/thing that would be damaged when struck by the failed portion of the tree. A target's exposure and/or frequency -of -use are taken into account in hazard assessments. The size of the part with the highest likelihood of failure is another element. The likelihood of failure is what these analyses attempt to forecast based on something relatively objective. All of our discussions take into account the fact that trees are living organisms, constantly actively changing. Typically, changes in status quo occur slowly (absent catastrophic events like chain saws and fires). We have needed to adopt even our best formulae and analysis from correlative concepts in other disciplines. As a result, all consultants employing these calculations do so with a healthy dose of caution — knowing these are only one of the tools in our analysis — attempting to allow enough margin so as not to shave safety factors too closely. 2.9 Modem literature points out a dichotomy that must be noted in such an analysis as here. On one hand, the fact that this oak can produce green leaves may be a positive element for this tree as a living organism. However, it is extremely important (Matheny, 4/98, p. 7) to differentiate between: a.) tree vigor, and b.) tree structural stability. A tree's vigor may be unrelated to its structural soundness (or lack thereof) (Bloch, 7/98, p. 34). It is also known that as a function of age, a particular specimen's ability to wall off decay fungi deteriorates (Matheny & Clark, 1994, p. 6, p. 20). 2.10 Risk (of failure) is a relative concept. We all assume some degree of risk in our daily lives — we get in an automobile and enter a world in which car accidents are commonplace. We mitigate our risk of such accidents by driving defensively, obeying stop signs and other traffic laws, avoid being on the road at tam when the bars close, and turn in our licenses when senile dementia becomes too overwhelming. Likewise with our trees, we reduce our risks with good tree care practices, including: implementing effective tree protection measures during construction, hiring tree care contractors whose crews make proper cuts, maybe deciding to install support (cables, bolts, props) or address pest control issues or take it down safely before it fails out of control. And, in the end, our tree decisions become a risk benefit analysis, too. We do what we can to "obey the signs" and apply good tree Gaze practices. But the final decision of how much risk one shoulders is ultimately the tree owner'. The arborists' analysis and opinions are one tool to help identify and categorize hazards and degress of risks. 3.0 Conclusions & Recommendations The severely compromised root Hazes of these two oak trees place them in a "Critical Risk of Failure" rating. Both #130 and 4132 have an accumulation of problems with development of decay and poor -structure, plus the declining vigor, plus root challenges with both vigor and loss. February 18, 2007 Oak #130 & #132 Status Report: Malavalli Residence, LAH. Page #4 of 6. Ray Morneau, Arborist ISACertified Arborist#WE-0132A 650.9647664 Their declining vigor, compromised structures, and unthrifty roots are no longer sufficient to support these trees within the guidelines of typically reasonable risk. We cannot predict when they will fail — and the trees would likely stand for a few months yet — but all factors considered, have a notably high risk of failure. Planning now to schedule its prompt removal would be prudent. Alternatively, twice -annual monitoring inspections to continue evaluating their changes in status quo would be required during the course of the construction project, and at least annually thereafter.

Coate, ASCA Consulting Arborist March 28, 2007 Job # 10-05-212-07 MALAVALLI TREES 0 130 - 137 Assignment: On March 28`", 2007, I met Nicole Horvitz and Leslie Hopper of the Town of Los Altos Hills at the Malavalli property to review the condition of Trees 4130 and 9132 and to estimate the effect of proposed grading on those as well as the rest of trees #130 through #137. Summary: It is my understanding that a building permit was issued in November 2005 which included grading in the area currently occupied by or adjacent to this semi -circular row of trees. In a previous report prepared by our office in October 2005 regarding these 7 trees, I commented that trees #130 and #132 were both capable of being preserved if the goal was to preserve as many trees as possible on site with the minimal level of risk tolerable by the owners. I suggested at that time that a combination of cables and supporting posts could artificially support these two trees over a long period, but there would always be some level of risk of limb failure. At that time a permit for grading had not been issued and that factor was not part of my equation in offering that opinion The proposed grading line would be far north of tree # 130 and would certainly necessitate the removal of # 130 and it would be so close to the trunk of tree # 132 that it would remove an excessive proportion of that tree's root system as well. Under these circumstances, i.e. the numerous decay sites in each of these trees when combined with the effects of proposed grading, I suggest there is no option but to remove those trees. In addition, tree # 131 will be so adversely affected that I suggest its removal be allowed as well. It is my understanding that the removal of those trees is important because of the proposed location of the swimming pool and other portions of the construction which must extend into the root zone and under the canopy of those trees. I suggest however that the grading line be amended from that proposed in proximity to trees 4133 through 4137 to maintain the canopy of those trees for the benefit of the view protection for neighbors directly north across the valley. In addition, it is my understanding that the Malavallis have offered to transplant significant trees to the areajust north of tree #130 to provide this screening desired by the neighbors directly across the canyon towards the north-northwest. PREPARED BY BARRIE D. COATE, CONSULTING ARBORIST MARCH 28'x', 2007 MALAVALLI TREES 8130- 137 If those trees were planted no farther than 15' north of the existing tree 4130, they should not only serve that function well, but provide longterm useful replacement for tree M130. Recommendations: I recommend that: 1. The removal of trees #130 and 4132 is allowed considering the grading which has been permitted combined with the many decay sites in each tree. 2. I suggest that tree #131 be removed as well due to the root damage which will occur when that grading occurs. 3. I suggest that the grading line be changed south of trees #133 through 4137 to comply with the grading line drawn on the enclosed plan. 4. I suggest that trees #133 through #137 have drop crotch pruning from the western sides of the canopies by a highly qualified certified arborist this winter to prevent limb drop from any of the long limbs which reach towards the west sun. This pruning should not simply be interior thinning of these already thin trees, but should be drop -crotch pruning from the ends of the longest limbs to reduce the length of those limbs back to shorter side branches. 5. I suggest root collar cleaning around each of these trees in an area at least 3' from the trunk down to the original grade. It would appear that fill soil has been pushed over the root collars of many of these trees causing the potential for root collar diseases including oak root fungus and water mold disease in the future. Specific Questions: To answer the specific questions asked by Mrs. Hopper: 1. "What is the condition of trees #130 and #132?" Answer: Fach of these trees have major significant decay sites in the trunk which would make them vulnerable to limb drop and breakage if artificial support was not provided for them. 2. "Given the construction of the residence having been approved, do you agree the trees should be removed? Answer: Under this set of circumstances, yes I agree that the trees should be removed. 3. "If the trees are to be removed, do you have recommendation on how the removal should be accomplished in order to minimize damage to other trees?" PREPARED BY BARRIE D. COATE, CONSULTING ARBORIST MARCH 29�, 2007 MALAVALLI TREES 4 130 - 137 Answer: Yes, I suggest that a protective fencing be installed at the margin of the adjusted grading line and that no equipment be allowed beyond that fence line or in areas beneath the tree canopies. 4. Is the proposed tree replacement feasible and will it provide adequate screening for the residents across the canyon on Foothill Drive?" Answer: I believe that the installation of Coast Live Oak (Quercus agrifolia) trees in the locations suggested on 25 to 40' centers will accomplish that goal very effectively and maintenance of trees # 133 through # 137 will accomplish the goal for neighbors north across the valley.

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 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. Trees are living organisms that fail in ways we do not fully understand. Conditions are often hidden within trees and below ground. Arborists cannot guarantee that a tree will be healthy or safe under all circumstances, or for a specified period of time. Likewise, remedial treatments, like medicine, cannot be guaranteed. Trees can be managed, but they cannot be controlled. To live near trees is to accept some degree of risk. The only way to eliminate all risk associated with trees is to eliminate all trees. Barrie D.

I will make sure the Planning Commission receives a copy of your message so that they are aware of your concems. In response to your questions, although the house is mainly a single -story structure, it reaches the maximum height in several areas and will involve commercial -scale construction. For example, the indoor swimming pool area will require the placement of huge windows, which are best positioned with a crane. The contractors would like to use this particular crane because the electric engine is cleaner and quieter than a regular gas engine. Also, if they leave it in place during construction instead of hauling it in and out numerous times, there will be less wear and tear on the roads. When the crane is shut down, it is 65 feet in height. Yesterday the contractors put a pole up to show how high that would be if the crane is allowed. They have offered to paint the crane dark green or whatever color would make it less obtrusive.

My understanding is this is a one story house, massive, but one story. If I did not need a crane for a 2 story 4/25/2007 Page 2 of 3 house, why do they for a one story?

In response to your questions: 1. A decision has not been made regarding tree removal and replacement. That decision will be made by the Planning Commission at their meeting on May 3rd. 2. On May 3rd the Planning Commission will consider an application for permit modification including grading, tree removal and replacement. Use of the electric crane will also be under consideration. 3. There are severe[ other items on the May 3rd PC agenda. 4. Construction will start as soon as building permits are issued. Permits for the accessory structures (the office and cabana) maybe issued this week. A permit for the main house will not be issued until the PC reviews the matter on May 3. Thank you for your comments on the crane. We will share your comments with the Planning Commission.

I also appreciate your faxing me a copy of the minutes from the public hearing as well as a copy of Barry's report. Upon re -reading the report it is clear that Mr. Coate did not specifically address the issue of the condition of trees 130 and 132 and their proposed removal. Because he makes several references to "Oaks #130.136° in the section of his report discussing grading and tree roots, it appeared that he was assuming that these trees would be present during possible excavation. He provides a general criticism of the report with respect to its lack of detailed and specific information about individual trees and states "a textual part of the report should be included that provides enough information about trees to be removed and reasons for removal, and specific tree preservation details for trees which are to be saved." In reviewing the minutes to the meeting I noticed that it only included my comments from the first time that I spoke, early in the meeting. I again spoke at the and of the public hearing. I was the one that asked specifically that trees #130, 132, 147, and 150 not be removed, not David Bulfur of Lucero Lane. The commissioners were not favorable towards retaining tree #150, a large eucalyptus which are now not welcome in Los Altos Hills, but asked the architect directly ff they were willing to keep trees #130, 132, and 147 and he responded yes. I understand the concerns about the health of trees #130 and #132. The second arborist's report obviously makes the case in more detail for their removal. I feel that the right next step is to seek Mr. Coate's evaluation of this second report and obtain a second opinion from him that is specific to trees #130 and #132. If Mr. Coate supports the conclusions of the second report then I would have no further objection to the removal of the trees. However, if Mr. Coate is of the opinion that the trees can be saved, then I would expect the applicant to proceed to implement Mr. Coate's recommendations for the preservation of these trees. In this situation, a difference in opinion of the experts should favor conservation — which Mr. Malivalli has repeatedly stated is his preference as well. I very much appreciate your comment to me on the telephone that any removal of trees #130 or #132 is an issue that would need to go back to the planning commission. I think the commissioners would expect to see that an aggressive effort was made to save the trees, and that removal should only happen if all the experts agree that it is not possible to save these two trees. I also appreciate your review of the issues surrounding the grading and tree roots. The applicant may ultimately have to adjust his plans to deal with the presence of tree roots from the other heritage oaks along the ridgeline.

I am forwarding this mail -see below- from my husband to you and to Joe at L.W.G.G. Inc. We definitely need to hear from and once again consult Barrie Coate before any action is taken on trees # 130 and # 132. I was told - and I think all of us at that meeting yesterday were- that all the arborists were on board with the decision that trees were not salvageable. I was truly dismayed to find out Barrie knew nothing about these new reports, let alone agreed with them. I now feel like we don't have all the information to make a decision regarding these trees. Please don't make any plans for their removal until we all sit down again with Barrie and review everything. Please have Leslie give my husband Mark a call this afternoon when she gets in. He will have hopefully gone over the "new" arborist's reports with Barrie by then. His number is 408-868-1336 or 408-690-1103. Thank you very much! Dianne Vernon Subject: Malavalli Oak Trees Dear Ms. Hopper, Dianne Vernon ---Original REALTORe Message ----- 110 First Street From: Mark Vernon Los All: 4022 Degheest; I am one of the neighbors who has been following the Malavalli project. I have recently learned via Anne DeGheest that the Town has given the approval to the Malavalli's to remove two large Oak trees. Two trees that they were told specifically at the public meeting six months ago that they were not to remove. I attended that public meeting, and when I spoke I was the person who specifically requested by number that these trees not be removed. My argument was based on the report of Barrie Coate, the arborist who had been hired by the Town to provide a second opinion regarding the health of these trees. Mr. Coate's report stated that although these trees had 4/26/2007 Page 2 of 2 i some hollow places that they were healthy and that with proper care and maintenance they did not need to be removed I called Mr. Coate today and asked him if he had been in contact with the Town regarding any follow-up to his report and he told me no. He was surprised to learn that yet another report has apparently been obtained by the property owner and submitted to the Town making the case for the removal of these trees. He asked me who authored this report and I told him I did not know. I will tell you that I have dealt with Mr. Coate professionally and greatly respect his knowledge and expertise. He has made a number of recommendations to my company, Ridge Vineyards, over the years. He has helped us save several specimen trees that were diseased and which were located very close to some of our buildings including our winery. Please re -consider the removal to those two trees. At a minimum I request that you have Mr. Coate review this new report prior to the any final approval of the removal of these trees.
