HomeMy WebLinkAbout3.1 I 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 RECOMMENDATION That the Planning Commission: 1. Approve the requested Site Development Permit, 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. y Planning Commission !!is--sr 27500 La Vida Real December 8,2005 Page 2 of 17 A DISCUSSION Site Data: Gross Lot Area: 8.03 acres Net Lot Area: 8.03 acres Existing Conservation Easement 3.50 acres Proposed Open Space Easements 1.25 acres Total Conservation/Open Space Easements 4.75 acres (59% of site) Average Slope: 25.8 % Lot Unit Factor: 5.314 Floor Area and Development Area: Area (square feet) Maximum Proposed Existing Increase Left Development Area 48,224 48,046 31,423 +16,623 +178 Floor Area 27,685 19,280* 8,623** +10,657 +8,405 *Does not include 5,752-s.£basement "Includes existing house and demolished house Site Planning The applicant requests approval .of a Site Development Permit for a two-story, five-bedroom residence with an attached six-car garage, daylighted basement,.indoor swimming pool, and three detached accessory structures including an office, garden pavilion, and decorative landscape tower. 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 corner 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 �1 1_ Planning Commission 27500 La Vida Real December 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 Parkin; 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 f 27500 La Vida Real December 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 corner is 44 feet from the south property line. Ling 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 L1.1) 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 framed. All planting required for screening or erosion control will be required to be planted prior to final inspection and occupancy of the new residence. i i i _ K n Planning Commission 27500 La Vida Real December 8,2005 Page 5 of 17 Fencing 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 concerns 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 L1.1 because they are 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 - 27500 La Vida Real December 8,2005 _y, 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#7. 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. Planning Commission _ 27500 La Vida Real 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 corner 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 first 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). Open 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. rA Planning Commission 27500 La Vida Real December 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 concerns 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 41 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 #124 and #180 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. - r Planning Commission 27500 La Vida Real December 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. Planning Commission 27500 La Vida Real December 8,2005 Page 10 of 17 ATTACHMENTS 1.

(LOA)has prepared this letter report with the express purpose of determining whether or not fencing on the above referenced, approximately 8-acre property would have an adverse effect on the movement of wildlife in the immediate vicinity of the site or within the region. This analysis is intended to provide to the Town of Los Altos sufficient information to aid them in their decision to approve the proposed project. The site is located at 27500 La Vida Real in Los Altos,*California(APNs: 182-20-054 and 182- 20-055), and is bordered by Natoma Road to the north, La Vida Real to the west and south, and open space to the east. Low to medium density housing surrounds the site, and the areas in between houses are forested. The site is irregularly shaped and ranges from 470 feet to 565 feet' National Geodetic Vertical Datum. The site can be found on the Mindego Hill U.S.G.S 7.5 minute quadrangle, in the northwest quarter of the northwest quarter of the southwest quarter of Section 36, Township 6 south,Range 3 west in the Mt. Diablo Meridian. The proposed project will set aside 4.8 acres(60%)of the approximately 8-acre site as a conservation easement. The remaining 3.2 acres will be the build-out area, and will consist of an approximately 17,000 square foot home, a separate office building, a small putting green, a small vineyard, and extensive gardens. The applicant wishes to fence in the garden areas using a 6- foot high wrought iron fence(vertical slats approximately 4"to 6"apart). The purpose of this fencing is to preclude deer from entering the landscaped areas. The town of Los Altos has expressed concern regarding the proposed fencing, especially in an area that carries runoff from the houses to the south of the property via an underground culvert. The area in question does not qualify as a drainage, creek or riparian area in a traditional sense, as there is no defined channel or a predominance of hydrophytic vegetation. While wildlife may use this area to access the site, deer and other animals are just as likely(if not more likely)to San Jose Office:6830 Via Del Oro, Suite 205 e San Jose, CA 95119 9 Phone:408-281-5885 a Fax:408-224-1411 Oakhurst Office:P.O.Box 2697 •49430 Road 426,Suite B 9 Oakhurst,CA 93644 9 Phone: 559-642-4880*Fax:559-642-4883 access the site from the conservation areas,which are more densely vegetated and offer natural • cover. Animals typically use riparian corridors for movement from one area of suitable habitat to another. This is due in large part to the typically gentle slope of riparian areas that offers easy movement for most species. The installation of deer-proof fencing, especially without forethought, alters the movement of medium to large size terrestrial wildlife and can lead to a decrease in biodiversity by precluding larger predators to remain in an area. In San Diego County, for instance, it was found that the presence of coyotes(Canis latrans)might actually improve biodiversity by suppressing the devastating effects of niesopredators(e.g., feral cats, raccoons and opossum)that wreak havoc on songbird populations. Therefore, altering large tracks of landscapes with fencing is inappropriate in many cases. However,the installation of deer-proof fencing should be looked at on a case-by-case basis. This project site currently supports a single-family house, open grassland(a mixture of manicured, native and ruderal),trees and a riparian area. The riparian area is an unnamed tributary of Deer Creek(located to the south and east of the site), and has a mature canopy consisting mainly of coast live oak Quercus agrifolia),valley oak(Quercus lobata), and California bay laurel(Umbellularia californica). The understory and surrounding vegetation consists mainly of poison oak(Toxicodendron&versilobum), horehound(Marrubium rulgare), curly dock(Rumex cris ,pus), coyote bush(Baccharispilularis)Italian thistle(Carduus pycnocephalus), little tarweed(Ma&a exiqua), and non-native grasses of European origin. Wildlife species that were directly observed on the property include western fence lizard (Sceloporus occidentalis), red-shouldered hawk(Buten lineatus), acorn woodpecker(Mekwerpes fonnicivorus), western scrub jay(Aphelocoma calffibmica), California towhee(Pipilo crissalls), eastern gray squirrel-black phase(Sciurus carofinensis), and western gray squirrel (Sciurus griseus). Indirect observations(scat and prints)of rabbit, likely cottontail(Sylvilagus nuttaffii) and black-tail deer(Odocorleus hentionus)were made. Other species that may occur on-site, especially within the riparian area are common bat species, dusky footed wood rat(Neoldina fuscipes)though no nests were noted during the reconnaissance visit, opossum(Didelphis virginiana), ringtail (Bassanscus astutus), raccoon(Procyon lotor), coyote(Canis latrans), feral cats(Felis catus), bobcat(Lynx rufts), and perhaps mountain lion(Puma concolor). Currently, deer and other wildlife move through the site in a broad manner. Although the applicant proposes to fence approximately 3.2 acres of the site to preclude deer from browsing on the landscaped areas, the proposed project will set aside 4.8 acres(600/9)of its total acreage via a conservation easement. This 60%of the site represents a much higher biological value than the proposed landscaped areas. Therefore, while the fencing will preclude wildlife from entering 400/9 of the site, it will not effect the regional movement of wildlife. Figure I shows movements of local wildlife in the immediate vicinity of the site, based on field observations made by LOA wildlife ecologist Mchele Korpos on 29 September 2005. In summary, using fencing that is impermeable to large mammals over large tracks of land, or an accumulation of smaller adjacent parcels, leads to a reduction in regional biodiversity. However, 2 Live OakAssociates,Inc. thoughtful placement of fencing(e.g., portions of a parcel close to home and garden areas)while still allowing wildlife movement on appropriate portions of a given parcel is not necessarily detrimental. It is our professional opinion that the proposed project would not have a significant effect on wildlife movement in the immediate vicinity of the site or within the region. If you have any questions or comments regarding our findings please contact me at your earliest convenience.

Grading associated with the demolished residence has resulted in several steep to very steep (47 to 65 percent inclinations) fill slopes along the perimeter of the ridge. Drainage at the site is characterized primarily by sheetflow directed away from the ridge, where it is intercepted by Deer Creek to the north and by a north-trending gully to the west. The Town Geotechnical Map indicates that the site is underlain, at depth, by Franciscan Complex greenstone. During our site visit we noted that Franciscan Complex melange (locally consisting of greenstone, limestone, and graywacke) is exposed in the walls of the demolished swimming pool excavation. Site surficial materials consist of sandy clay colluvium and soil. T he pole;�tially active Altamont fault, pote:Mially active Monta Vista fault and potentially active Berrocal fault are located approximately 900 feet southwest, 1,300 feet east, and 2,000 feet southwest, respectively, of the proposed residence. The active San Andreas fault is located approximately 2.9 miles southwest of the property. CONCLUSIONS AND RECOMMENDED ACTION The proposed development is potentially constrained by expansive surficial soil materials, creep along moderately steep to very steep slopes, the presence of existing artificial fill beneath parts of the proposed building site, instability of temporary basement cuts, and susceptibility of the site to strong seismic ground shaking. The Project Geotechnical Consultant has characterized apparent site geotechnical constraints and has provided recommendations that, in general, appear appropriate for site conditions. We do not have geotechnical objections to the proposed layout of site improvements. Consequently, we recommend geotechnical approval of permits for the construction of site improvements with the following conditions: 1. Geotechnical Plan Review - The applicant's geotechnical consultant should review and approve all geotechnical aspects of the final project building and grading plans (i.e., site preparation and grading, site drainage impro.,emonts and design parameters for foundations) to ensure that their recommendations have been properly incorporated. In addition, the Project Geotechnical Consultant should address the following items: a) The Project Geotechnical Consultant has indicated that near-source factor Na for the site is 1.2 (based on the Type A San Andreas fault as the controlling fault). The Project Geotechnical Consultant should re-evaluate this seismic parameter based on the location of the site with respect to Type B faults (e.g. Altamont, Berrocal, and Monta Vista faults). b) It appears that the northwestern part of the proposed residence is located near the top of a fill prism with very COTTON, SHIRES & ASSOCIATES, INC. ' r :- Leslie Hopper August 23, 2005 Page 3 L0185 steep slopes up to 10 feet in height. The Project Geotechnical Consultant should evaluate whether proposed structures in this area will be founded on adequate bearing materials. Structures in this area may warrant removal and/or replacement of existing fill. C) The Project Geotechnical Consultant has recommended that foundation piers be embedded at least 6 feet into underlying bedrock or at least 10 to 16 feet below existing grade. The Project Geotechnical Consultant should clarify which embedment criterion controls the drilled pier depth (whichever is greater). For conformance with prevailing local standards for hillside residential construction, the Consultant should consider minimum pier embedment ueptlhs of S to 10 feet into bedrock. d) The Project Geotechnical Consultant should verify that proposed steel reinforcement for the piers meets minimum geotechnical standards (i.e., the minimum local standard of practice includes minimum 16-inch diameter piers reinforced with a cage containing a minimum of four No. 5 vertical bars). e) The Project Geotechnical Consultant should either verify that the design of the proposed swimming pool shell is sufficient to resist hydrostatic and active lateral earth pressures, or the Consultant should specify pool shell design criteria. The results of the plan review should be summarized by the geotechnical consultant in a letter and submitted to the Town Engineer prior to acceptance of documents for building permit plan-check. 2. Geotechnical Field Inspection-The geotechnical consultant should inspect, test (as needed), and approve all geotechnical aspects of the project construction. The inspections should include,-but not necessarily be limited to: site preparation and grading, site surface and subsurface drainage improvements, and excavations for foundations and retaining walls prior to the placement of steel and concrete. The results of these inspections and the as-built conditions of the project should be described by the geotechnical consultant in a letter and submitted to the Town Engineer for review prior to final (as- built) project approval.

Leslie Hopper Town of Los Altos Hills 26.379 Fremont Road Los Altos Hills,CA 94022 Fax: (650)941-3160 Prepared by: Barrie D. Coate Consulting Arborist November 14th,2005 Job# 10-05-212 REVIEW OF THE ARBORISTS REPORT FOR THE MALAVALLI RESIDENCE I Assignment On November 10'', 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 1-4. As example, an explanation seems appropriate for the information on those charts for trees #79 and 81. Why is there an SOD threat? Or tree #123, a large, well formed Aleppo Pine is to be removed. I would want more explanation for this decision and even some pictures explaining the claimed poor conditions. In 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: I. 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 grown up into this fill, making the trees dependant upon that fill and these roots for a significant part of their moisture and nutrient supply. 2. 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 2 _ r 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." 3. 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#136, a 31.5" Oak. 4. 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. 5. 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, I suggest that this grading not be allowed. - Respectfully submitted, Barrie D.

The project will be Energy Star Qualified. Alo gwith this we have also included suggested Green Architecture practices.They are as follows: 1. The home will have a computer manager that will manage the various systems associated with the project such as mechanical,electrical,plumbing,security,shades,phones etc. 2. Mechanically,the home will be zoned for 8 different zones. Within each zone there will be mechanically controlled dampers to shut off individual rooms not using heating or cooling. This will allow each occupant to use heating or cooling as needed for the occupied spaces only. All zones will have an automated"Whole-Attic Fan"system to vent out the hot air from the attic. 3. All mechanical units will have highest level of energy star certification for the project. 4. There will be several water heaters that will also be used to allow for zone control. Tankless water heaters shall be specified for the project. All water heaters will have recirculating pumps in order to save water consumption. All hot and cold water lines shall be insulated in unconditioned spaces. All toilets for the project shall be specified as"Low Flow Models." When available all appliances shall have a Energy Star rating. 5. The use of solar energy has been proposed for the project. The solar panels are located on the project site plan. These panels will provide hot water for the entire project. The indoor pool and spa will be heated via solar panels. The solar panels will be supplemented with regular energy during cloudy days. The hot water generated from the solar panels will also be used for radiant floor heating systems that will be designed for the home. 6. We are currently researching the use and integration of the"Photovoltaic(PV)Panels on the flat roof areas. This will help generate electricity for the project that can be used for certain components such as security lighting,outside landscape lighting or walkway illumination. The inherent problem with these systems is the integration with the Home Manager. We are currently talking to suppliers for the Lighting Control Systems to help with the integration. 7. The pool equipment will have highest level of energy star certification for the project. 8. The skylights in the indoor swimming pool are located at the roof to help conserve energy. They bring in natural daylight to the pool and spa area. The skylights provide natural ventilation for the indoor swimming pool which helps in conserving energy that would be otherwise used for the operation of the mechanical system for ventilation purposes. 9. There is a lighting control system that will allow zoning for each room. Within each room there will be additional zones(scenes)that will permit efficient use of power. High energy transformers,light bulbs and fluorescent lighting will be used for efficient use of power. 10. The project will have a minimum of 2x8 stud wall construction at all perimeter walls. In some cases the walls may be thicker. This will allow us to use R-19 and greater insulation for all exterior walls. The sub-floors will have R-30 insulation. The roof will have a 2 layer insulating system made up of R-38 and R11 for a total of R-49. If recycled fiberglass insulation qualifies we propose to use it wherever possible. This far exceeds the California T- 24 energy compliances. 11. All exterior doors and windows will have insulated"low E"glazing and will be supplemented with tinting to allow for greater insulating values. 12. The home will use recycled.products as much as possible. Currently the products that are being considered are engineered lumber, structural steel,carpet,wood flooring,wood products for cabinets,trims and various ceiling treatments. 13. The waste generated on the project will be segregated for recycling. 14. .The project will use Low/No VOC and Formaldehyde-Free Paint,Low-VOC Water-Based Wood finishes and Solvent-Free Adhesives wherever possible. Landscape and Environment Items: 1. Using composted yard waste for soil amendment. 2. Using recycled wood for wood chip mulch. 3. Using recycled wood and plastic for landscape header board. 4. The only trees that will be removed from the site will be Eucalyptus and Pine trees. All other trees will be protected in place or moved and replanted. 5. Use of an Efficient Irrigation System that will have the following characteristics: a. Rain Sensor b. Flow Meter(detects breaks/leaks) c. Central control will provide detail reporting = ;r d. Controller with download daily weather up dates and adjusts watering times. This will avoid urban runoff. Above and beyond this,our firm is in contact with PG&E and special energy consultants to look into other possibilities that are available for the project. I hope this letter addresses the concerns about the high levels of energy and water consumption. If you have any questions regarding this letter please feel free to call me.

However, not having received a written request to postpone, we proceeded to discuss it, and we support in full the current proposals as described to me by Leslie, in particular, requesting two areas of conservation easement, one to protect the "gully" area that already has a drainage easement, and one behind the house on the region of steep slope that connects to an existing conservation easement. Our only additional comment was our concern that the existing drainage easement, that runs completely across the property, should not be blocked by landscaping walls, as this will be the only remaining corridor for wildlife movement through the parcel, and the only access into the "gully" area. Currently, there is a wall indicated at the end LI of the gully.

They are as follows: 1. The construction of such a pathway with the provided specifications from the Town of Los Altos Hills (refer to attached sketch)would create significant amount of grading,cutting of existing mature historic trees,construction of retaining walls and bridges. These are all prohibited in"open space conservation easements." 2. The neighbors from the surrounding area have expressed severe concern about this pathway at our neighborhood meeting for the project. The major concerns are as follows: a. Encroachment into the riparian area that has been dedicated to an open conservation easement area with significant historic trees,deer creek and steep slopes. They are all concerned with erosion that could occur due to the construction of the pathway. b. Serious hazard created at the intersection of the proposed pathway and Natoma Road due to the fact that Natoma is a very narrow winding road and the pathway would create serious visibility issues due to the site's steepness. 3. The cost of construction and approval process from various agencies to construct such a pathway would be significantly higher than the"in-lieu fees." 4. Our general contractor has walked the site for the proposed pathway and has several construction issues. Please refer to the attached letter from LWGC. 5. There are some serious environmental and biological issues with the proposed pathway alongside of deer creek. Please refer to the letter from our team's wildlife ecologist dated 11/2/05(letter from Live Oaks Associates,Inc.) 6. The construction of the pathway would alter the natural habitat,topography and vegetation. It would also encroach into the banks of Deer Creek. This will cause some erosion problems. After discussing with our consultants we have collectively come to a conclusion that building the proposed pathway will be in conflict with the goals of the open space conservation area and the Town's Wildlife Corridors. 7. Mr. and Mrs.Malavalli have been asked to dedicate more land towards open space conservation and restrict themselves from developing(landscaping and building)in these areas. Furthermore,we changed our landscape plans to reflect that no planting would occur in these areas. On one hand we are being asked to dedicate land for open space conservation while on the north side of the property we are being asked to construct a pathway in an open space conservation area. There seems to be a conflict with the design goals for open space conservation area on the same project. 8. 1 have listed some thoughts and planning principals from the Town of Los Altos Hills"A guide to understanding Conservation Easements"handbook. These seem to be in conflict with the construction of the pathway. They are as follows: a. To leave for our children and grandchildren a heritage that has not been dug up and paved over and-it's ironic word-HUMANIZED. b. Under a conservation easement the landowner promises to keep the land in its natural condition without extensive disturbance. c. The natural conditions of conservation easements often provide unique terrain, vegetation,watersheds,wildlife habitats or wildlife corridors, and are fundamental to maintaining a rural,open space atmosphere,and these are the values that make our Town a desirable place to live. d. "Any now there is a considerable body of public opinion in favor of keeping for our children's children,as a priceless heritage, all the delicate beauty of the lesser and all the burly majesty of the mightier forms of wild life." - Theodore Roosevelt. The goal of the project has been to preserve the natural surroundings that the site offers. Mr. and Mrs. Malavalli bought two properties and combined them into one so that they could create an estate type home.The design goal has been to create an architectural masterpiece that responds to the site. Our design reflects that. Once complete the home will feel like it has been there for years. This is due to the fact that there is a huge inventory of large trees,vegetation and wildlife that would be preserved. Furthermore,we are supplementing the existing landscaping with a large number of mature trees and shrubs. We strongly believe in providing pathways for the citizens of Los Altos Hills. We would gladly build a pathway if it were in an area that would not be in conflict with the alteration of preserved lands. We have spent a significant amount of time and money to convince Planning Staff that this is an area that should remain in its natural state. We have offered to pay the in-lieu fees since the very beginning of this process but have been offered nothing but resistance. We suggest that this is one area we should not encroach into, and is the best heritage we would leave behind for our children and grandchildren. I hope this letter addresses the concerns about the construction of the pathway in a very sensitive natural habitat. If you have any questions regarding this letter please feel free to call me.

Deer Creek(the Creek) and tributaries thereof occur within this 20-foot setback area. This reach(riparian area)of Deer Creek supports a mature canopy consisting mainly of valley oak (Quercus lobata),coast live oak(Quercus agrifolia), and California bay(Umbellularia califomica). The understory consists mainly of Himalayan blackberry((Rubus discolor), California rose(Rosa californica), and poison oak(Toxicodendron diversilobum). As such,this riparian corridor offers a medium to high biotic value for local fauna,with the limiting factor being its proximity to low-density housing. The thick leaf litter and decaying logs in this habitat provide a moist microclimate suitable for amphibians such as the California newt(Taricha torosa), ensatina(Ensatina eschscholtzi), arboreal salamander(Aneides lugubris),California slender salamander (Batrachoseps attenuatus),western toad(Bufo boreas) and Pacific tree frog(Hyla regilla). Western fence lizards(Sceloporus occidentalis), and southern alligator lizards(Elgaria multicarinata)may also occur in this habitat. Avian species such as California quail(Callipepla californica),black phoebes(Sayornis negricans),ash- throated flycatchers(Myiarchus cinerascens). Anna's hummingbird(Calypte anna), acorn woodpecker (Melanerpes formicivoms),Nuttall's woodpecker(Picoides nuttallii),downy woodpecker(Picoides pubescens),northern flicker(Colaptes auratus), SteIlar's jay(Cyanocitta stellari), and western scrub jay (Aphelocoma californica), among other avian species are likely residents of this riparian corridor. Winter migrants would include Townsend's and yellow-ramped warblers (Dendroica townsendi and D. coronata,respectively),and ruby-crowned kinglets(Regulus calendula). Summer migrants breeding here could include orange-crowned warblers(Vermivora celata),black-headed grosbeaks(Pheucticus melanocephalus),and warbling vireos(Vireo gilvus). Avian predators(i.e.,raptors)such as white-tailed San Jose Office: 6830 Via Del Oro, Suite 205 -San Jose,CA 95119 -Phone:408-281-5885 - Fax:408-224-1411 Oakhurst Office: P.O.Box 2697 •49430 Road 426,Suite B -Oakhurst,CA 93644-Phone: 559-642-4880- Fax: 559-642-4883 SI kites,red-shouldered hawks,red-tailed hawks and great horned owl (Bubo virginianus),may roost or nest within this riparian corridor. A number of mammals occur or are likely to occur in this habitat,either using this riparian area as all or part of their home range,or using it as a movement corridor. Such species include the pallid bat (Antrozous pallidus),California mastiff bat(Eumcps perotis),Virginia opossum(Didelphis virginiana), Eastern grey squirrel(Sciurus cardinensis)—black phase,western grey squirrel(Sciurus griseus),ringtail (Bassariscus astutus),raccoon(Procyon lotor), coyote(Canis latrans), gray fox(Urocyon cinereoargenteus), striped skunk(Mephitis mephitis),cougar(Puma concolor),bobcat(Lynx rufus), and black-tailed deer(Odecoileus hemionus columbianis). The area along the property line on the northern edge of the CE slopes gently to the south for a short distance(approximately three to eight feet), and then the slope associated with the CE is rather steep (e.g., greater than 15% slope in most areas, approaching 30-40% in some areas)on both sides of the Creek. Creating a trail within the CE would necessitate the crossing of the Creek or its tributaries between one to three times, depending on where the trail alignment would occur. The removal of woody vegetation or significant trimming of trees would also be required. It is highly probable that these activities would require permits from various agencies. For instance, if bridges were used to cross the Creek, and were constructed using culverts,the U.S.Army Corps of Engineers (Corps)would need to be consulted, and it is likely a 404 Clean Water Act permit would need to be acquired. Removal of woody vegetation or installation of footings for a bridge between the high water mark and the top of bank, would require consultation with the California Department of Fish and Game(Department), and likely necessitate a 1602 Streambed Alteration Agreement. The Regional Water Quality Control Board would likely require a 401 Certification regardless of Corps or Department involvement. The need for such permits and agency involvement would trigger the CEQA process (e.g., a Mitigated Negative Declaration or an Environmental Impact Review). Due to the size, species and function of many of the trees within the riparian area,they may fall under the moniker of a"Heritage Tree" as defined by the Town of Los Altos Hills, which may require a permit to remove or trim them. Furthermore,depending on the number of trees to be removed and the degree to which they provide habitat for a variety of species, their removal would likely require mitigation (usually at a 3:1 replacement to loss ratio). Due to the fact the habitat within the CE consists of a mature canopy, off-site mitigation would be likely. Please let me know if you have any questions or concerns regarding this recap of our walk through today.

I)ear Kartik, On Friday November 4; 2.005 after our morning meeting, l drove to the property and walked the entire northeast property line. The purpose was to investigate the feasibility of constructing a horse/human walking path along this line. The requirements Y base my opinion on are: (a) town document labeled "pathway standards detail C" and (b) town document labeled "horse path general plan". As a contractor, with years of experience in the Los Altos lflls and having built many of these same trails, I am quite familiar with the requirements of the town. From a constructability standpoint, building this trail would require (a) a small retaining wall along one or possibly both sides of trail, (b) a Section of at least six inches of compacted granite for footing as required by the town of Los Altos Hills and (c) at least two small bridges would neod to be built. The volume of material and equipment traffic to facilitate constructing the trail would be considerable. All of this traffic (human, equipment, and material) would flow directly off of or onto Natoma Road. With no staging area,this presents a sizeable risk to the safety of people performing the work and traffic on Natoma Read. The choice of location for this pathway entrance doesn't allow for a staging area. Tberei'orc, a secondary traffic path would be required, which would leave a sizeable ..car in the; conservation easement. Based on the steepness of the slope, the singularity of the entrance/exit paint, the forced method of linear construction always working on the ,path to prevent any further erosion or scarring of the natural surroundings; creates excessive costs. In my estimation, the cost of building this path to the Malavalli`s will be at least ten fold that of a normal %ection of town s;inctioned pathway. Sincerely, urzcl, President, LWG , Inc cc: 14.06:05 I /'D R RECEIVED Off-Road Pathway between the properties of 27608 Voglff' JLos ALTOS HMS and 27500 La Vida Real in Los Altos Hills 7 November2005 I and my family have lived in Los Altos Hills for over 22 years. I have during this enter time had an off-road pathway along my property. At times in the spring I have cut the grass all the way from Black Mountain Road to Elena along path B3.21 to make this path more accessible. I do not plan to apply for any permits any time soon, but I did apply and received a development permit for my property in 1989. This is on file with the Town and no additional off-road pathways were requested. If this new off-road path,B3.22, goes in, 56% of my property will have off-road paths. I have never met, I have-never talked with nor do I know the person or persons who purchased 27500 La Vida Real in Los Altos Hills, CA 94022. It is my understanding that the Town of Los Altos Hills may deny a development permit - - for Lands which include 27500 La Vida Real in Los Altos Hills, CA unless they build(at any cost) a human/horse pathway through what has been for decades a nature reserve. This path may be on or directly adjacent to my property. I gathered my information because I questioned surveyors who used my property during multiple surveys (at least 4 to date) and private citizens. No notice from the Town or its representatives (e.g. Environmental or Pathways Committees)was given to me, as an effected resident, about the many negotiations for or against construction of the pathway designated as B3.22; it was only through the time I spent on the telephone from surveyor to engineer to architect to city planer to neighbors to Council member(s)that I got at least part of the story. I would like to thank those who truthfully gave information. I have serious concerns with an off-road pathway B3.22 between the above mentioned properties (27608 &27500 LAH). 1. This potential pathway was extensively reviewed during the last Pathway Master Plan update(Spring 2005) and at least 8 people involved in the Master Plan physically toured this creek-side setting in March 2005. At that time it was decided by this group that it was not advisable to build a path for practical, safety, and environmental reasons. The Planning Commition recommended that this path be removed from the Master Pathway Plan(MPP). This is documented in Attachment#1. It was also documented until recently on the Town's Web site(Attachment#2). The Town Council chose to reject the Planning Commissions recommendations. I would like to know why and why it is now time to build this path. 2. The residents adjacent to this potential pathway where not notified of construction discussions which have been ongoing for months, yet a non-member of the Pathway Committee toured and strongly influenced discussions which were not open to residents along the proposed pathway. It may be legal,but I feel not involving effected residents but inviting `pathway friends' to tours and discussions is inappropriate. A 3. The area of the proposed human/horse pathway has one of the few year-round, spring- fed creeks which many indigenous animals routinely use. Is this the best place for human encroachment? 4. The site has extremely steep slopes. This is a good place for indigenous animals but not for people with dogs and horses. .5. How will vegetation removal effect soil erosion and maybe even landslides? Is there and environmental impact study? Can we not find a better place to walk with or without our domesticated animals? I do not think defoliation,tree cutting and building retaining walls are consistent with asking residents to devote over half of the same lands to be dedicated to permanent open space. 6. The proposed,new path does not significantly add access already afforded by existing off-road path B3.22. After 22 years of personal observation I do not think the proposed path would aid children going to school or neighbors visiting each other. I would like to see data(not unsubstantiated opinions)which refute my 22 years of personal observations regarding this specific site. I would be willing to assist polling residents along the existing-pathway, the proposed creek pathway as well as those which are 'near the pathways on their opinions. I think local residents should have at least a voice in the 'discussions before people with special agendas get to influence the Town. 7. Can we not negotiate with the developer(s)of 27500 La Vida Real to get funds to build and/or maintain pathways which are better investments for our community? I would be willing to assist in this endeavor. 8. The entrance/exit for the proposed path B2.21 has safety issues. It is on a very narrow part of Natoma Road and on a tight curve. People and horses entering or exiting this proposed path would have limited visibility to vehicular traffic even at 25 MPH. These are just some of my opinions. Please let me know if you would like me to expand on the merits of this path as well as the procedures used to negotiate development permits. Regards, Brian Macknick,Ph.D. 27608 Vogue Court Los Altos Hills, CA 94022 I support efforts of volunteers of the Town of Los Altos Hills. It is often a difficult and thankless job. Without their endeavors the Town would not be the great place in which I brought up my children. We may agree to disagree,but at least we should all have access to information in this Internet world to voice our opinions. We cannot do this without free and open information from the Town and its committees. (NOV. Z a O S PL4Nvlv(r COM . ?0WN r,QvaC,iL 83,27'.'

Mr. and Mrs. Malavalli invited my husband and me to their current home on Sunday, October 30, to review the drawings of the new residence, along with the other neighbors of La Vida Real. Their architect Kartik Patel and his team presented the project to us for a good part of the afternoon. There were several questions from various neighbors during the presentation and the team was able to respond to.our satisfaction. We are the future next-door-neighbors of the Malavalli's and would be impacted the most by the layout of the building and the grounds. As a result of what we learned at the meeting, we now support the project and look forward to seeing it built. The Malavalli's new home will be a welcome addition to La Vida Real and an enhancement of our neighborhood. We list here a few of the factors that are most appealing to us. The preservation of the existing landscape is refreshing. The Malavalli's have boxed several existing trees that were affected by the demolition of the original house. These are currently being taken care of so that they can be replanted. The proposed additional landscaping will further enhance the neighborhood. .2. The design retains the path for deer travel at our shared property line at our request. 3. The design incorporates sensitivity towards energy conservation and "green architecture." 4, Mr. and Mrs. Malavalli salvaged for recycling a significant amount of the original home that was demolished. We appreciate the fact that they will do the same with the second home that is also slated for removal. 5. The design takes into account the neighbors' privacy issues, and also preserves the views of each of the neighbors' homes. We especially like the fact that the house is, for the most part, a single-story building. 6. The design of the.driveway ensures that La Vida Real would not be impacted by traffic visiting the new residence. 7. Not only is the architecture of this estate-type home outstanding, but the design also keeps more than fifty percent of the property under Open Space Preservation. The completed project would be a credit to the neighborhood and to Los Altos Hills. The.only concern we have for the project is the fact that the Pathway Committee for the Town of Los Altos Hills is proposing a path at the north end of the property by Deer Creek. We feel that this is an Open Conservation Area and is an environmentally sensitive area. The construction of a pathway in this area is not only intruding into this area but is also unsafe for pedestrians. The termination at Natoma Road also makes it very dangerous. In closing, I wish to reiterate my full support for the project and would hope that the Planning Commission feel the same way I do. Thank you, and Best Regards, .Sandy Laws-Miller Los Altos Hills, CA 94022
