RECOMMENDATION Staff and the Planning and Transportation Commission (P&TC) recommend that the City Council approve the following: I. Negative Declaration, prepared for the proposed recreational facility of the property located at 3208 Alexis Drive, in accordance with the California Environmental Quality Act (Attachment B). 2. A Record of Land Use Action approving a Site and Design Review and Conditional Use Permit application to allow a new 8,987 square foot tennis court and associated site improvements, subject to the findings and conditions of approval contained in the Record of Land Use Action (Attachment A). BACKGROUND AND PROJECT DESCRIPTION The 1.57 acre project site is located within the Open Space Zone District. The Palo Alto Comprehensive Plan land use designation for the project site land is Single Family Residential. The project site is located at the terminus of Alexis Drive in the Palo Alto foothills adjacent to Foothills Park and the Enid Pearson Arastradero Preserve, west of the Foothill Freeway and within the City's Urban Service area. The subject property is located directly north of two adjacent parcels under the same ownership; the three parcels together fonn a 5.5 acre residential site. One parcel is developed with a 13,400 square foot (sq. ft.) primary residence and the second parcel is developed with a 3,359 sq. ft. guest-house. The rwo homes are located near the ridges of the two developed lots, visible from Vista Point in Foothills Park. The elevation of the CMR: 386:10 Page I of 4 subject parcel is lower than the developed parcels, on the opposite side of the hill and sloping away from Vista Point. Thc 8,887 square-foot tennis court is proposed as the primary use of an Open Spaee parcel, requiring approval of a Condition Use Permit. The court would be for daytime use by the guests, property owners and residents of the home and guest house on the adjacent properties. The tennis court would be surfaced in asphaltic concrete. The project also includes a paved dininglkitchen area onlhe north and east side of the tennis court, a storage room below the tennis court, stone retaining walls and a wood and steel pergola. The tennis court would be enclosed by a ten-foot tall fence, to be constructed of mesh fabric over black vinyl-covered sleel eore wire, mounted on top of a three-foot tall retaining wall on the north side. Substantial landscape screening is proposed, with 29 trees in a variety ofspccics and native and/or drought tolerant shrubs, and all existing trees on the site would remain. 'The proposed site lighting includes 24 path lights and six down-lights for the dining area. COUNCIL PURVIEW AND REVIEW CRITERIA Palo Alto Municipal Code (PAMC) Section 18.28.070 Additional Open Space District Regulations, item (b)(2), requires the placement of a Site and Design Review project in the OS district on consent calendar following a recommendation of approval by the P&TC. This process reflects the 2009 process changes for review of Open Space development. Similarly, pursuant to P AMC Section 18.77.060 (t), a Conditional Usc Permit may be approved by Council on consent calendar following P&TC recommendation. The City Council may: (l) Adopt the findings and recommendations of the Planning and Transportation Commission: or (2) Remove the recommendation from the consent calendar, which shall require three votes, and: a) b) Discuss the application and adopt findings and take action on the application based upon the evidence presented at the hearing of the Planning and Transportation Commission; or Direct that the application be set for a new hearing before the City Council, following which the City Council shall adopt findings and take action on the application. The Council's decision shall be based upon the findings of Site and Design Review Combining District, the Open Space Development Criteria of the Comprehensive Plan, and the findings for Conditional Use Permit approvaL These items are provided in the Record of Land Use Action (Attachment A). PLANNING AND TRANSPORTATION COMMISSION RECOMMENDATIONS The project was reviewed by the Planning and Transportation Commission (P&TC) on September 29, 2010. A majority of the commissioners believed that a new tennis court was preferred in the Open Space Zoning District over a new house, which would be an allowed use on this parcel. One commissioner did not believe the tennis court would be compatible with the Opcn Space District. The P&TC, with a votc of 6-1-0, recommended that the City Council adopt CMR: 386:10 Page 2 of4 the Negative Declaration and approve the Site and Design Review and Conditional Use Permit to allow the tennis court and associated improvements. The P&TC voted to incorporate additional language in the conditions of approval to: 1) prohibit roofing or enclosing the tennis court, 2) cJaIify that the approval of a recreational facility would be for a tennis court only, and 3) limit the use of the tennis court use to the property owner and residents of the adjacent residences at 3230 and 3220 Alexis Drive and their guests. The Record of Land Use Action has been amended accordingly. No members of the public spoke on this item. POLICY IMPLICATIONS The project complies with the Comprehensive Plan and applicable Zoning Ordinance regulations as set fOl1h in detail in the Draft Record of Land Use Action. Staff believes that the project is supported by the findings for approval of the Site and Design Review and Conditional Use Pelmit applications. The proposed tennis court is customarily associated with residential uses and has been designed to be compliant with the Comprehensive Plan's Open Space Criteria. ENVIRONMENTAL REVIEW The project is subject to environmental review under provisions of the California Environmental Quality Act (CEQA). An environmental impact assessment was prepared for the project and staff determined that no potentially adverse impacts would result from the development, and therefore, the project would have a less than significant impact on the environment. The Negative Declaration was made available for public review beginning September 2, 2010 through September 22,2010. No comments on the environmental document have been received during the public review period.

Background. The City Council of the City of Palo Alto ("City Council") finds, determines, and declares as follows: A. Suzman and Cole Design Associates, on behalf of Open Space LLC, property owner, has requested the City's approval for the construction of an, 8,897-square foot private recreational facility, which includes a tennis court and associated improvements on a vacant lot of approximately 1.57 acres associated with two adjacent residential lots all under the same ownership within the Open Space Zoning District. The recreational facility would be an accessory use to the residential residences located at 3220 and 3230 Alexis Drive. The request ("The Project") is subject to a Conditional Use Permit and Site and Design Review approval. B. The site is designated on the Comprehensive plan land use map as Single Family Residential and is located within Open Space (OS) zoning district. C. Following review, the Planning and Transportation Commission (Commission) reviewed the Project on September 29, 2010, and recommended approval. The Commission's recommendations are contained in CMR:XXX:10 and the attachments to it. SECTION 2. Environmental Review. The City as the lead agency for the Project has determined that the project is subject to environmental review under provisions of the California Environmental Quality Act (CEQA) under Guideline section 15070, Decision to Prepare a Negative Declaration. An environmental impact assessment was prepared for the project and it was determined that no potentially adverse impacts would result from the development, therefore, the project would have a less than significant impact on the environment. The Negative Declaration was made available for public review beginning 1 September 3, 2010 through September 23, 2010. The Environmental Impact Assessment and Negative Declaration are contained in CMR: XXX:10. SECTION 3. 1. The use manner that will be existing or potent S and Design Review Findings will be constructed and operated orderly, harmonious, and compatible uses of adjoining or nearby sites. in a with The proposed tennis court would be located behind the existing residences as seen from Vista Point and away from the public street. Because the facility is proposed at a lower grade, it would not be visible from Foothills Park or Vista Point. The facility would be cut into the hillside to minimize visibility from adjacent properties. A large amount of landscaping is proposed to screen the site from offsite views. The project utilizes natural materials, such as flagstone, in a neutral color to blend into the surroundings. 2. The project consistent with the goal of ensuring the desirabili ty of investment, or the conduct of business, research, or educational activities, or other authorized occupations, in the same or adjacent areas. The proposed tennis court is customarily associated wi th residential uses. Al though on a separate parcel, the recreational facility would be to be used by residents of the two adjacent parcels under the same ownership as the subject parcel. The project is designed to be compatible with the existing site and surrounding open space area. Project construction is subject to compliance with the Uniform Building Code and other applicable codes to ensure safety and high quality of development. 3. Sound principles of environmental design and ecological balance are observed in the project. The proposed architectural and site changes are consistent with the Site and Design Criteria adopted by the City Council. Sustainable design features incorporated into the project include the planting of native species, the use of water conserving irrigation, and the use of permeable pavers. The proj ect will not have a significant environmental impact as indicated by the proposed Negative Declaration for this project. The tennis court would be used during daylight hours only. Accordingly, the only light proposed is low-level lighting for the walking paths and the area under the pergola. 2 4. The use will be in accord wi th the Palo Al to Comprehensive Plan. Policy L-1 of the 1998 2010 Palo Alto Comprehensive Plan encourages the City to retain undeveloped land west of the Foothill Freeway and Junipero Serra as open space, with allowances made for very low-intensity development cons with the open space character of the area. The project site is west of the Foothill Freeway and is located within the City's Urban Service Area (map L 2 of the Comprehensive Plan). The Palo Alto Comprehensive Plan land use designation for the project site is Single Family Residential and one residence is permitted on each of the parcels of the project site. The proposed development's impervious coverage is less than the maximum impervious area allowed on the property. The project does not include development of a house, but a recreational facility considered a residential accessory use. The design consistent and compatible with the Palo Alto Comprehensive Plan in that the design promotes Policy N-6, which states, "through implementation of the Site and Design process and the Open Space zone district regulations, minimize impacts of any new development on views of the hillsides, on the open space character, and the natural ecology of the hillsides." The proposal is subject to the Site and Design Review process, complies with the applicable development standards and intent of the Open space zone district, including the Open Space Criteria therein derived from policies in the Palo Alto Comprehensive Plan. Compliance with the Open Space Criteria is as follows: 1. The development should not be visually intrusive from public roadways and public parklands. As much as possible, development should be sited so it is hidden from view. The proposed recreational facility would be located down--slope behind the owner's two existing residences. Because the facility is located behind and is at a lower grade than the residences that are vi from Foothills Park, it would not be visible from Foothills Park or Vista Point. The facility would be cut into the hillside to minimize visibility from adjacent properties. The recreational facility is located at towards the rear and away from any public street. A large amount of landscaping is proposed to screen the site. 3 2. Development should be located away from hilltops and designed to not extend above the nearest ridgeline. The proposed facility would not be located at the top of the hill and would not extend above the ridgeline. The facility is proposed to be cut into the hillside to minimize visibility. The retaining walls would be located as close to the northern edge of the site to bring the area to be developed as far downhill as possible. 3. Site and structure design should take into consideration impacts on privacy and views of neighboring properties. The proposed recreational facility is sited to minimize views from adjacent properties. It would be located outside of setbacks, built into the hillside and away from the ridgeline to reduce massing. The applicant is also proposing to plant a substantial amount of landscaping to provide additional screening, including over twenty large specimen trees. The tennis court is designed to be used during daylight hours only. As such, only path lighting and down-lights below the arbor area are proposed. 4. Development should be clustered, or closely grouped, in relation to the area surrounding it to make it less conspicuous, minimize access roads, and reduce fragmentation of natural habitats. The new facility would be located residences. The new development would be tennis court. No new access roads preserving natural habitats. near the existing clustered around the are proposed, thus 5. Built forms and landscape forms should mimic the natural topography. Building lines should follow the lines of the terrain, and trees and bushes should appear natural from a distance. The retaining walls would follow the existing contours, to minimize retaining wall heights, and to fit in better with the existing topography. The facility would be built into the hillside, reducing the massing. The native and/or drought tolerant trees and shrubs to be planted have been specifically chosen and placed to provide screening, but also to maintain the natural look of the open space. 6. Existing trees with a circumference of 37.5 inches, measured 4.5 feet above the ground level, should be preserved and integrated into the design. 4 The proposal includes the protection and retention of all existing trees on site. 7. Cut is encouraged when it is necessary for geotechnical stability and to enable the development to blend into the natural topography. Fill is generally discouraged and should never be distributed within the driplines of existing trees. Locate development to minimize the need for grading. The grading for the project would consist of 75% cut to 25% fill to help minimize the visual impact to neighboring properties. The project includes 1,784 cubic yards of cut and 661 cubic yards of fill. The majority of graded soil, 1,123 cubic yards, would be taken offsite. The remaining fill would not be placed at the drip-lines of any existing or planned trees. 8. To reduce the need for cut potential runoff, large flat surfaces should be avoided. and 11 expanses and of to reduce impervious The facility is sited towards the middle the site to avoid adding to the footprint of the two adj acent homes. The recreational facility was cut into the hillside and designed so runoff would be minimized through the use of a slow release system to reduce the amount of runoff. 9. Buildings should use natural materials and earthtone or subdued colors. The material for all walls is limestone in a beige tone. Flagstone is proposed for the sitting areas. Both materials are of earth-tone colors. Given the configuration, the retaining walls would be the most visible element from offsite. The walls would also be covered with vines to soften the construction and allow it to blend better with the surroundings. 10. Landscaping should be native species that require little or no irrigation. Immediately adjacent to structures, fire retardant plants should be used as a fire prevention technique. The Fire Department has reviewed the plant selection and has no objections. The applicant is proposing primarily native species, with a few adaptive and drought tolerant plants. A condition of approval included to require the use of fire retardant plants. 5 11. Exterior lighting should be low-intensi ty and shielded from view so it is not directly visible from off-site. All lighting would be low voltage and kept to a minimum. Safety lights are proposed along the paths. Down-lights are proposed for beneath the arbor. The tennis court would only be illuminated for safety as no nighttime use is proposed. The project will be conditioned such that the lights will be low intensity and directed downward to avoid any impact upon surrounding property and open space lands. Criterion 12 and 13 do not apply to the project as no new roads are proposed and the development is not within an unincorporated area. SECTION 4. Site and Design Review Approval Granted. Site and Design Review Approval is granted by the City Council under Palo Alto Municipal Code Section 18.30(G) .070 for application 10PLN-00164, subject to the conditions of approval in Section 8 of the Record. SECTION 5. Conditional Use Permit Findings. 1. The proposed use, at the proposed location, will not be detrimental or injurious to property or improvements in the vicinity, and will not be detrimental to the public health, safety, general welfare, or convenience. The project was designed to minimize visibility from offsite locations, especially from Foothills Park and Vista Point. The tennis court would be located behind the two residential buildings and is located at a lower point. Because the tennis court sits below the residential buildings, it will not be visible from Foothills Park. The grading would reduce visibility of the court from adjacent lots. A substantial amount of landscaping, including 29 new trees, would provide additional screening. The private tennis court, for use by the property owners and their guests, is a typical accessory use for larger residential lots and would not introduce any noise impacts not customarily associated with larger residential properties. Thus, the proposed use will not be detrimental to public health, safety, general welfare or convenience. 2. The proposed use will be located and conducted in a manner in accord with the Palo Alto Comprehensive plan and the purposes of the zoning Ordinance. The proposed tennis court will be located and conducted in a manner consistent with both the Comprehensive plan and the Zoning Ordinance. The tennis court would be located outside of 6 all property setbacks and the project would not exceed the maximum amount of impervious surface allowed on the parcel, consistent with the development standards for properties located in the Open Space Zoning District. The proj ect also compl s with the Open Space Criteria and Comprehensive Plan Polic Palo Alto Comprehensive Plan land use designation for the project site is Single Family Residential and one residence is permit ted on each of the parcels of the proj ect site. The project is a low intensity use customarily associated as an accessory use to a primary residential use. The project does not include development of a house as a primary use. A private recreat use without a primary residential use is conditionally allowed. The proposed tennis court would function as an accessory use to the residences on the adjacent lots under the same ownership. SECTION 6. Conditional Use Permit Approval Granted. s granted by the City Council under Palo Alto Municipal Code Section 18.77.060 for application 10PLN-00164, subject to the conditions of approval in Section 8 of the Record. ====_7,-.

SIDEWALK, CURB & GUTTER: As part of this project, the applicant must replace those portions of the existing sidewalks, curbs, gutters or driveway approaches in the public right-of-way along the frontage(s) of the property that are broken, badly cracked, displaced, or non-standard, and must remove any unpermitted pavement in the planter strip. Contact Public Works' inspector at 650-496-6929 to arrange a site visit so the inspector can determine the extent of replacement work. The site plan submitted with the building permit plan set must show the extent of the replacement work or include a note that Public Works' inspector has determined no work is required. The plan must note that any work in the right-of-way must be done per Public Works' standards by a licensed contractor who must first obtain a Street Work Permit from Public Works at the Development Center. 35. STREET TREES: The applicant may be required to replace existing and/or add new street trees in the public right-of-way along the property's frontage. Call Public Works' arborist at 650-496-6905 to arrange a site visit so he can determine what street tree work, if any, will be required for this project. The site plan submitted with the building permit plan set must show the street tree work that the 14 arborist has determined, including the tree species, size, location, staking and irrigation requirements. The plan must note that in order to do street tree work, the applicant must first obtain a Permit for Street Tree Work in the Public Right-of-Way from Public Works' arborist. 36. GRADING & DRAINAGE PLAN: The plan set must include a grading & drainage plan prepared by a licensed professional that includes existing and proposed spot elevations and drainage flow arrows to demonstrate proper drainage of the site. The plan must show subgrade drainage systems and how the drainage will work within the site. Grading will not be allowed that increases drainage onto, or blocks existing drainage from, neighboring properties. Public Works generally does not allow rainwater to be collected and discharged into the street gutter. 37.

PROJECT LOCATION 3208 Alexis Drive Palo Alto, CA Parcel Numbers: 182-54-008 The project site is located in the southwest section of the City of Palo Alto, in the northern prut of Santa Clara County, west of U.S. Highway 101 and of State Route 82 (EI Camino Real), as 3208 Alexis Drive/10PLN·00164 Page 1 Negative Declaration shown on Figure 1, Regional Map. The project site is located at the terminus of Alexis Drive in the Palo Alto Foothills. The improvements are proposed for one of three parcels that make up this site and down slope from the existing two residences, which are under the same ownership. The propelty is located adjacent to Foothills Park and near Arastradero Creek. The adjoining properties to the north, south, east and west are open space parkland owned by the City, as shown on Figure 2, Vicinity Map. 7. GENERAL PLAN DESIGNATION: The General Plan designation is Single Family Residential, per the Palo Alto 1998 " 2010 Comprehensive Plan. This land use designation allows one main dwelling unit on each lot, as well as conditional uses requiring permits such as churches and schools. Specific areas may be zoned to allow second units or duplexes where they would be compatible with neighborhood character and not create traffic and parking problems. 8. ZONING The subject site is zoned OS (Open Space) [regulated by the Palo Alto Municipal Code (PAMC) Chapters 18.28]. The specific regulations of this chapter and the additional regulations and procedures established by other relevant chapters of the Zoning Code shall apply to the OS Open Space. The project, a private recreational use accessory to a residence, is pelmilted as a condilionaluse in this zone district. 9. PROJECT DESCRIPTION The proposal is for a Site and Design Review and Conditional Use Permit approval of a private recreational use (tennis COUlt) on a vacant parcel of a three-parcel single family residential property under the same ownership. The modifications include additional landscaping for screening, an outdoor dining area with counter and sink, an approximately 150 sq. ft. storage area built into the hillside under the tennis court and retaining walls. No changes are [lroposed to the existing residential buildings. The project includes substantial landscaping changes that will involve grading approximately 2,445 cubic yards of dirt, which includes 2,784 cubic yards of cut and 661 cubic yards of fill, to create a flat surface for the tennis court. No trees are proposed to be removed as part of this project. Approximately 26 new trees would be planted to provide screening. SURROUNDING LAND USES AND SETTING The project site is bounded by Alexis Drive to the east and sun'ounded by City owned Foothills Park to the nOlth, south and east. The closest single-family residences are located to the north along Alexis Drive. 11. OTHER PUBLIC AGENCIES • County of Santa Clara, Office of the County Clerk-Recorder 3208 Alexis Drive/l0PLN-00164 Page 2 Negative Declaration ENVIRONMENTAL CHECKLIST AND DISCUSSION OF IMPACTS EVALUA TlON OF ENVIRONMENTAL IMPACTS 1) A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. [A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e. g. the project falls outside a fault rupture zone), A "No Impact" answer should be explained where it is based on project-specific factors as well as general standards (e. g. the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis).] 2) All answers must take account of tbe whole action involved, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts. 3) Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. Potentially Significant Impact" is appropriate if there is substantial evidence that an effect may be significant. If there are one or more "Potentially Significant Impact" entlies when the determination is made, an EIR is required. 4) "(Mitigated) Negative Declaration: Less Than Significant With Mitigation IncOlporated" applies where the incOlporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less than Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section 17, "Earlier Analysis," may be cross-referenced). 5) Earlier analysis may be used where, pursuant to the tieling, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063 (C)(3) (D). In this case, a brief discussion should identify the foJlowing: a) Earlier Analysis Used. Identify and state where they are available for review. b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c) Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures IncOlporated," describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project. 6) Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g. general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 3208 Alexis Drive/10PLN-00164 Page 3 Negative Declaration I 7) SUPPOlting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8) The explanation of each issue should identify: a) the significance criteria or threshold, if any, used to evaluate each question; and b) the mitigation measure identified, if any, to reduce the impact to less than significance. DISCUSSION OF IMPACTS The following Environmental Checklist was used to identify environmental impacts, which could occur if the proposed project is implemented. The left-hand column in the checklist lists the source(s) for the answer to each question. The sources cited are identified at the end of the checklist. Discussions of the basis for each answer and a discussion of mitigation measures that are proposed to reduce potential significant impacts are included. A AESTHETICS .

DISCUSSION: The proposed project is subject to the Site and Design Review Process to ensure compliance with the City of Palo Alto Municipal Code and Comprehensive Plan policies and to allow public review. The recreational facility is also a conditional use subject to the Conditional Use Permit process to ensure that the project would not negatively impact the subject site, the immediate area or the City. The project consists of a new tennis COUlt. landscaping for screening purposes, retaining walls, a small storage 3208 Alexis Drive110PLN-00164 Page 4 Negative Declaration I facility built into tbe billside, and a trellis. The majority of the site is developed with two single family residences and no additional buildings are proposed. The existing residences are located on a high point of the property and are visible from Vista Point in Foothills Park. However, the proposed recreational facility is located down slope of the residences and would not be visible from Foot Hills Park. The applicant is proposing to utilize primarily native tree species to provide substantial scrcening around the new facility. The applicant is proposing to cut morc than fill to minimize appearance of the tcnnis court. The retaining walls would consist of limestone and vine plantings to blend better into the hillside and to soften the appearance. All other materials, including the trellis, have been designed to blend with the sUiToundings. The project is not located in or near any scenic highways. Mitigation Measures: None. B.

DISCUSSION: The subject project will not generate more vehicle tdps because no additional buildings or any substantial additions are proposed. The project site is not located in an area that contains uses or activities that are major pollutant emitters. The project is not expected to result in a significant impact on air quality. The project may result in temporary dust emissions due to construction activity. The City of Palo Alto uses the Bay Area Air Quality Management District's (BAAQMD) thresholds of significance for air quality impacts, as follows: Construction Impacts: The project would involve demolition, excavating, grading. and paving activities which could cause localized dust related impacts resulting in increases in particulate matter (PM IO). Dust related impacts are eonsidered potentially significant but may be mitigated with the application of standard dust control measures. Construction equipment would also emit NO, and ROC. However, in order for emissions from construction equipment to be considered significant, the project must involve the extensive use of construction equipment over a long pedod of time. Based on the size of the proposed project. emissions of NO, and ROC are anticipated to be less than significant. The project would be subject to the following City's standard conditions of approval: The following controls shall be implemented for the duration of project construction to minimize dust related construction impacts: • All active construction areas shall be watered at least twice daily. • All trucks hauling soil, sand, and loose matetials shall be covered or shall retain at least two feet of freeboard. • All paved access roads, parking areas, and staging areas at the construction site shall be swept and watered daily. • Submit a plan for the recovery/recycling of demolition waste and debtls before the issuance of a demolition permit. • Sweep streets daily if visible soil material is can'ied onto adjacent public streets.

No trees are proposed for removal. The applicant is proposing to plant 26 new native specie trees to provide additional screening, In the immediate vicinity of the project, there are no tiparian or tree habitats for the candidate, sensitive, or special status species in the area. No endangered, threatened, or rare animals, insects and plant species have becn identified at this site. Tree preservation guidelines will be incorporated into the conditions of approval stich that the project will not have a significant impact on the code protected trees and the project will have no impact on any other biological resources. The proposed project will have no impact on biological resources and will require no mitigation. Per the standard conditions of approval requiring protection of trees. the project would result in a Jess than significant impact to biological resources. Mitigation Measures: None. 3208 Alexis Drive/1 OPLN-00164 Page 8 Negative Declaration : , E CULTURAL RESOURCES .

MapL7 Eliminate important examples of major periods 1,2 of California history or prehistory? X DISCUSSION: The Comprehensive Plan indicates that the site is in a moderate archaeological resource sensitivity zone. Most of the City area east of Interstate 280 is designated in this zone. A standard condition of approval would require Archaeological Monitoring and Data recovery Plan (AMDRP) be prepared by a qualified archaeologist if any archaeological or human remains are encountered during grading or construction activities. The Santa Clara County Medical Examiner's office would be notified to provide proper direction on how to proceed. If any Native American resources are encountered during construction, construction would cease immediately until a Native American descendant, appointed by the Native American Heritage Commission of the State of Califomia, is able to evaluate the site and make further recommendations and be involved in mitigation planning.

X .... ,- g) Expose people or property to major geologic hazards that cannot be mitigated through the l. 4, 5, X use of standard engineering design and seismic safety techniques? DISCUSSION: The entire state of California is in a seismically active area. According to the Comprehensive Plan the project site is not in an area that is subject to very strong ground shaking in the event of an earthquake or in an area subject to expansive soils, surface rupture, liquefaction, or earthquake induced landslides. Development of the proposed project would be required to confonn to all requirements in the Uniform Building Code, which includes provisions to ensure that the design and construction of all buildings includes provisions to resist damage from earthquakes to the extent feasible and acceptable. The potential onsite exposure to geological hazard~ will therefore be less than significant. No mitigation is required. The Public Works Department has found the proposed grading plan consistent with City requirements. Standard conditions of approval require submittal of a final grading and drainage plan for the project for approval by the Public Works Department prior to the issuance of a building pennit. The application of standard grading. drainage, and erosion control measures as a pan of the approved grading and drainage plan is expected to avoid any grading-related impacts. 3208 Alexis Drivell0PLN-00164 Page 10 Negative Declaration The projeet will not involve the use of septic tanks or altemative wastewater disposal systems.

DISCUSSION: The proposed projeet will not involve the handling, transportation, use, disposal, or emISSIOn of hazardous materials. The projeet site is not identified by either the California Environmental Protection Agency or the Califomia State Water Resources Control Board as a hazardous materials site. The project is not expected to pose airport-related safety hazards. The proposed project will not interfere with either emergeney response or evacuation. The project site is located in a designated fire hazard area and the proposal has been reviewed by the Fire Department. The previous project was designed to incorporate all feasible fire prevention design features for the two existing buildings. A standard condition of approval will be included requiring that the project comply with the 2007 California Building Code Chapter 7 A to address fire prevention in a hazard area.

The project site is not located in a lOO-year flood hazard area and would not impede or redirect flood flows. The project site is not in an area that is subject to seiche, tsunami, or mudflow. With the City's required conditions of approval, the water impacts of the project will not be significant The majority of the site will remain permeable, The project will create a de minimum contribution because the site is already developed with two buildings and the project. The new third parcel will only be minimally changed with the addition of a new driveway with permeable pavers, perimeter trail and spa. The environmental conditions will essentially be the same whether or not the project is implemented. The standard conditions of the project approval require that a grading and drainage plan be submitted which includes drainage patterns on the site and from adjacent properties, and an erosion control plan. The contractor will be required to incorporate best management practices (BMPs) for storm water pollution prevention in all construction operations, in conformance with the Santa Clara Valley Nonpoint Source Pollution Control Program.

DISCUSSION: The proposed project is for a ptivate recreational facility on a vacant parcel under the same ownership as the two adjacent parcels developed with one primary residence and one guest house. Recreational uses in the Open Space Zoning district may be allowed as primary use via a conditional use permit. The Policy L-J of the 1998·20 I 0 Palo Alto Comprehensive Plan encourages the City to retain undeveloped land west of the Foothill Freeway and Junipero Serra as open space, with allowances made for very low­ intensity development consistent with the open space character of the area. The project, consisting of one recreational facility associated with an adjacent residential use, is consistent with this policy. The project site is west of the Foothill Freeway and is located within the City's Urban Service Area (map L-2 of the Comprehensive Plan). The Palo Alto Comprehensive Plan land use designation for the project site is Single Family Residential and one residence is permitted on each of the parcels of the project site. The project's impervious coverage is less than the maximum impervious area allowed on the vacant parcel. The applicant is not proposing to place a house on the parcel, but a private recreational facility for the use of residents of adjoining homes under the same ownership The proposed architectural and site changes comply with the Site and Design development regulations and conform to the intent of the Open Space zone district. The design is consistent and compatible with applicable elements of the Palo Alto Comprehensive Plan in that the design promotes the following policies for development in the Open Space, including: Policy N-6: Through implementation of the Site and Design process and the Open Space zone district regulations (P AMC 18.28), minimize impacts of any new development on views of the hillsides, on the open space character, and the natural ecology of the hillsides. The applicant proposes grading that utilizes more cut than fill and materials that blend with the adjacent buildings and hillside. ft is located behind the existing residences and on the down slope of the property, so that the new facility would not be visible from Foothills Park. The view of the facility as proposed from down slope would be interrupted by vegetation proposed with this project and limited because it will be cut into the hillside. No lights are proposed for the tennis court. The project will comply with all plans for conservation of biological resources as mitigated, and would not impact farmland. 3208 Alexis Drive/1 OPLN·00164 Page 14 Negative Deolaration !

DISCUSSION: The City of Palo Alto has been classified by the California Department of Conservation (DOC), Division of Mines and Geology (DMG) as a Mineral Resource Zone I (MRZ-I). This designation signifies that there are no aggregate resources in the area. The DMG has not classified the City for other resources. There is no indication in the 2010 Comprehensive Plan that there are locally or regionally valuable mineral resources within the City of Palo Alto. Mitigation Measures: None. K NOISE .

DISCUSSION: Grading and new construction may result in temporary increases in local ambient noise levels. Typical noise sources would include mecbanical equipment associated with demolition, excavation, grading and noise of construction in the building. Such noise will be short tenn in duration. The City's standard conditions of approval limit the bours of construction and require tbat the applicant comply with the requirements of the Palo Alto Noise Ordinance, Chapter 9.10 PAMC, Once completed, long-term noise associated with the revised project would he from recreational activities on the tennis court and would be within acceptable noise limits typically associated with residential uses. The proposed tennis court is an accessory use that is associated with an existing residence. Therefore. no noise impacts are anticipated. The project site is not located within an airpOlt land use plan or within the vicinity of a private airstrip. Mitigation Measures: None. 3208 Alexis Drive/10PLN-00164 Page 16 Negative Declaration L.

MANDATORY FINDINGS OF SIGNIFICANCE Issues and Supporting Information Resources Sources Potentially Potentially Less Than No Impact Significant Significant Significant Would the project: Issues Unless Impact Mitigation Incorporated aJ Does tbe project have the potential to degrade the quality of the environment, X substantially reduce the babitat of a fisb Or wildlife species, cause a fish Or wildlife population 10 drop below self-sustaining 1,2-Map levels, threaten to eliminate a plant Or animal LA,5 community; reduce tbe number or restrict the range of a rare Or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? b) Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a X project are considerable when viewed in connection with the effects of past projects, 1,2,5 the effects of other current projects, and the effects of probable future projects)? c) Does the project have environmental effects which will cause substantial adverse effects X on human beings! either directly or 1,5, ! indirect! y? DISCUSSION: The project would not have an impact on fish or wildlife habitat, nor would it impact cultural or histoIic resources. The uses are approptiate for the site and the development would not result in an adverse visual impact. There is nothing in the nature of the proposed development and property improvements that would have a substantial adverse effect on human beings, or other life or environmental impacts. The San Francisco Bay Area Air Basin (SFBAAB) is cuncntly designated as a nonattainment area for state and national ozone standards and national palticulate matter ambient air quality standards. SFBAAB's nonattainment status is attributed to the region's development history. Past, present and future development projects contribute to the region's adverse air quality impacts on a cumulative basis. By its very nature, air pollution is largely a cumulative impact. No single project is sufficient in size to, by itself, result in nonattainment of ambient air quality standards. Instead, a project's individual emissions contribute to existing cumulatively significant adverse air quality impacts. If a project's contribution to the cumulative impact is considerable. then the project's impact on air quality would be considered significant. The Bay Area Air Quality Management District's (BAAQMD) approach to developing a Threshold of Significance for Green House Gas (GHG) emissions is to identify the emissions level for which a project would not be expected to substantially conflict with existing California legislation adopted to reduce statewide GHG emissions needed to move us towards climate stabilization, If a project would generate 3208 Alexis Drive/10PLN-00164 Page 22 Negative Declaration GHG emissions above the threshold level, it would be considered to contribute substantially to a cumulati ve impact, and would be considered significant. The Tbresholds of Significance for operational-related GHG emissions are: • For land use development projeets, the threshold is compliance with a qualified GHG reduction Strategy: or annual emissions less than 1,100 metric tons per year (MT/yr) of C02e; or 4.6 MT C02e/SP/yr (residents + employees). Land use development projects include residential, commercial, industrial, and public land uses and facilities . • For stationary-source projects, the threshold is 10,000 meltic tons per year (MT/yr) of C02e. Stationary-source projects include land uses that would accommodate processes and equipment that emit GHG emissions and would require an Air District permit to operate. If annual emissions of operational­ related GHGs exceed these levels, the proposed project would result in a cumulatively considerable contribution of GHG emissions and a cumulatively significant impact to global climate change. The proposed project would not create any new operational GHG emissions. The tennis court facility is accessory to the primary existing residential use and will be used by the homeowners in a non­ commercial capacity. The projeet will not create any additional vehicle trips beyond what already occurs. During the construction there will a temporary increase in emissions, this discussion is provided in the Air Quality section of this report.

I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a ''potentially significant impact" or "potentially significant unless mitigated" impact on the environment, but at least one effect: 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, hut it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required.

Environnlcntal Assessment: An Initial Study and Negative Declaration has been prepared in accordance with California Envirornnental Quality Act (CEQA) requirements. Zoning District: OS (Opcn Space). RECOMMENDATION: Staff recommends that the Planning and Transportation Commission (PTC) recommend that the City Council adopt a Negative Declaration (Attachment B) and approve the Record of Land Use Action (Attachment A) approving the request for a Site and Design Review and a Conditional Use Peffi1it to allow the development of a private recreational facility on a vacant parcel of land in the Open Space District. SUMMARY OF LAND USE ACTION: Commission Purview All development in the Open Space (OS) district is subject to the Site and Design and Review regulations set forth in Palo Alto Municipal Code (P AMC) Cbapter 18.28.070(b) and Open Space District development standards. A Conditional Use Permit is required because the project includes the development of a tennis court as the primary use of a vacant parcel of land in the Open Space District. The project site is a separate parcel ofland under the same ownership as the adjacent developed parcels providing the primary and secondary residences. If the tennis court were proposed to be located on the same parcel as the residence, it would be permitted as City of Palo Allo Page 1 an accessory use and would be subject only to the Site and Design Review process required for development in the Open Space District. The purview of the PTC is to review the project for compliance with Open Space Review criteria, Open Space development standards and Comprehensive Plan policies and to confirm that approval findings for the Site and Design Review and Conditional Use Pennit can be made. The Record of Land Use Action provides draft approval findings. The PTC may recommend approval, approval with suggested changes, or denial. Following a positive recommendation by the PTC, the project will be forwarded to the City Council for approval on their consent calendar. BACKGROUND The project site was included in the 91 acres of land in the Palo Alto foothills subject to a 1978 Devclopment Agreement where 25 of the 91 acres were designated for clustered development and the remaining acreage was designated as public open space. The 25 acres were subdivided into ten lots and in 1979, the nine lots, including the proposed site, were entitled for single­ family residential use where up to 3.5% impervious site coverage was allowable based upon an assumed 10-acre site area. A tenth parcel remains undeveloped as part of the property exchange agreed upon by the City and landowners. Two Site and Design Review approvals have been granted for the two parcels with the residences now owned by Open Space LLC. The first Site and Design Review approval was granted in May 2000 to a previous owner for the construction of two homes on two lots (3220 and 3230 Alexis Drive) under the same ownership. Open Space LLC purchased both developed parcels, which are connected via a "tying agreement", as well as the adjacent vacant parcel, and received Site and Design Review approval in March 2008 for modifications to the 5.5-acre residential site, including site improvements on the vacant pareel to extend the existing driveway, trail, landscaping, and provide an in-ground spa. Site Description The project site is loeated in the Palo Alto foothills adjacent to Foothills Park and the Enid Pearson Arastradero Preserve, west ofthe Foothill Freeway and within the City's Urban Service. The site's Palo Alto Comprehensive Plan land use designation is Single Family Residential and the site is located within the Open Space Zone District. The subject property is a 1.57 -acre parcel having a 33% slope, is located directly north of the primary residence and guest-house. It is part of an overall 5.5-acre site comprised of three parcels of land located at the terminus of Alexis Drive. The two homes are located near the ridges of the two developed lots, visible from Vista Point in Foothills Park. The elevation ofthe subject parcel is lower than the developed parcels, on the opposite side ofthe hill and sloping away from Vista Point. The primary single-family residence, located on a 1.57-acre parcel, has approximately 13,400 square feet (s.f.) of floor area. The guest-house, located on a 1.91-acre parcel, has approximately 3,359 s.f. of floor area. The primary residential parcel and the subject pareel have direct access onto Alexis Drive, whereas the guest-house parcel is a flag lot with limited street frontage. PROJECT DESCRIPTION The project is the eonstruetion of a private recreational facility as a primary use of an Open Space City 01 Palo Alto Page 2 parcel, for use by the property owners living in their homes on the adjacent property. The proposal includes a 7,200 square foot tennis court surfaced in asphaltic concrcte, a paved area on the north and east side ofthe tennis court for dining (445 s.f.) and an outdoor kitchen (22 s.f.), a ISO-square foot storage room to be located below the tennis court, and stone retaining walls. A wood and steel pergola, similar to those existing on the adjacent parcels, is proposed for the dining arca. A ten-foot tall fence, to be constructed of mesh fabric over black vinyl-covered stcel core wire, would enclose the tennis court. The fence along the north side would be mounted on top of a three-foot tall retaining wall. The outdoor kitchen would include a small refrigerator, sink and storage area. The tennis court would be used only during daylight hours. The proposed site lighting includes 24 path lights and six down-lights for the dining area. Substantial landscaping is proposed to provide additional screening, with 29 trees in a variety of species and native and/or drought tolerant shrubs. All existing trees would remain. SUMMARY OF KEY ISSUES: Staff has identified four primary issues: the visibility of the site, grading, landscaping, and impervious surfaces. Compliance with the development regulations is analyzed in the attached table and, with the Open Space Criteria, is cited in the draft Record of Land Use Action. A discussion ofCondilional Use Permit and Site and Design Review findings, including the project's confomlance with Comprehensive Plan policies, is provided below. Visibility of Site The existing residences on the adjacent parcels are visible from Vista Point in Foothills Park. However, the proposed facility would be located down the slope from these parcels and would not be visible from Vista Point. The City's Open Space Supervisor, Lester Hodgins, has detennined that the project would not impact views from Foothills Park or Arastradero Preserve. The new facility may be partially visible to residents or occupants located farther down the hill from the site, including users of the Palo Alto Hills Golf and Country Club (P AHGCC). However, the proposed location of the facility below grade eoupled with strategic placement of trees would minimize the views from below. Dirk Zander, PAHGCC General Manager, has stated that the elub has no objections to the project. The native trees proposed throughout the site would maximize privacy for the occupants and provide sufficient screening along the project's perimeter. Once mature, the proposed trees would provide maximum screening of the site. Grading A substantial amount of grading is proposed to create a flat court by cutting into the 33 percent slope. The total volume of grading would involve 2,445 cubic yards (c.y.) of soil, of which 1,784 c.y. would be cut and 661 c.y. would be fill. Approximately 1,123 c.y. of soil would be taken off site. The remainder would be used on site for this project. The applicant has provided detailed preliminary grading plans, ineluding site sections on Plan Sheets L7.5 and 7.10, to disclose the proposed amount of grading. The proposed grading is consistent with the Open Space criteria and Comprehensive Plan policies in that there would be more cut than fill, and the retaining walls were designed to follow the existing contours to minimize wall heights and match the existing topography. Although grading is proposed to create a flat area for the tennis court, it was designed to minimize visibility when viewed from off site. City of Palo AnD Page 3 Landscaping A total of29 trees would provide screening of the proposed court. The 17 new trees include ten 48 inch box sized Coast Live Oaks, one 48-inch box sized Blue Oak, and six 48-inch box sized Valley Oaks. In addition, twelve Olive trees would be planted. The combination of trees would achieve a natural mixed canopy for a more natural oak-woodland and grassland zone and would avoid creation of a mono culture of trees. The 29 new trees on the vacant parcel, along with the trees previously approved for installation, would bring the total number of new trees on the subject property to 45. Once construction on all three parcels is completed, over 350 new trees will be in place across all the parcels. The project also includes the planting of a variety of shrubs and perennials, including the Dwarf Strawberry Tree (shrub form), English Boxwood, California Wild Lilac, Pacific Wax Myrtle and Verbena. Imperviolls Area The project plans indicate that approximately 11,421 s.f. of impervious site coverage is proposed. This includes 1,859 s.f. of impervious coverage approved on the parcel as part of the previous approval. The total impervious coverage is below the 15,246 s.f. allowed via the 1978 Development Agreement (3.5% impervious coverage of an assumed ten acre Open Space District lot). The 11,421-square foot impervious coverage total includes the tennis court, the kitchen, stairs and retaining walls plus the 1,859 s.f. attributed to previously approved stone walls and stairs and 50% of the area of the permeable gravel perimeter path, consistent with the Open Space Zoning District Requirements. A detailed list and breakdown of impervious coverage are provided by the applicant in a table on the title sheet of the plan set. Conditional Use Permit Approval Findings 1. The proposed use, at the proposed location, will not be detrimental or injurious to property or improvements in the vicinity, and will not be detrimental to the public health, safety, general welfare or convenience. The project was designed to minimize visibility from offsite locations, especially from Foothills Park and Vista Point,. Because the tennis court sits below the residential buildings and below grade, it will not be visible from Foothills Park or Vista Pointe. The grading would reduce visibility of the court from adjacent lots. A substantial amount of landscaping, including 29 new trees, would provide additional screening. The tennis court is a typical accessory use for larger residential lots and would not introduce any noise impacts not customarily associated with larger residential properties. Thus, the proposed use will not be detrimental to public health, safety, general welfare or convenience. 2. The proposed use will be located and conducted in a manner in accord with the Palo Alto Comprehensive Plan and the purposes of the Zoning Ordinance. The proposed tennis court would be located and conducted in a manner consistent with both the Comprehensive Plan and the Zoning Ordinance. The tennis courts are located outside of all setbacks and the project would not exceed the maximum amount of impervious surface allowed on the parcel, consistent with the development standards for properties located in the Open Space Zoning District. The project also complies with the Open Space Criteria and Comprehensive Plan City of Palo Alto Page 4 Policies. The Palo Alto Comprehensive Plan land use designation for the project site is Single Family Residential and one residence is permitted on each of the parcels of the project site. The project is a low intensity use customarily associated with residential use of a property. The project does not include development of a house on the subject parcel. A private recreational use of a parcel without a primary residential use is conditionally allowed. The new use would function as an accessory use to the residences on the adjacent lots under the same ownership. Site and Design Review Approval Findings 1. The use will be constructed and operated in a manner that will be orderly, harmonious, and compatible with existing or potential uses of adjoining or nearby sites. The proposed recreational facility would be located behind the existing residences as seen from Vista Point and away from the public street. Because the facility is proposed at a lower grade, it would not be visible from Foothills Park or Vista Point. The facility would be cut into the hillside to minimize visibility from adjacent properties. A large amount of landscaping is proposed to screen the site from offsite views. The project utilizes natural materials, such as flagstone, in a neutral color to blend into the surroundings. 2. The project is consistent with the goal of ensuring the desirability of investment, or the conduct of business, research, or educational activities, or other authorized occupations, in the same or adjacent areas. The proposed recreational facility is customarily associated with residential uses. Although on a separate parcel, the recreational facility would be used by residents of the two adjacent parcels under the same ownership as the subject parcel. The project is designed to be compatible with the existing site and surrounding open space area. Project construction is subject to compliance with the Uniform Building Code and other applicable codes to ensure safety and high quality of development. 3. Sound principles of environmental design and ecological balance are observed in the project. The proposed architectural and site changes are consistent with the Site and Design Criteria adopted by the City Council. Sustainable design features incorporated into the project include the planting of native species, the use of water conserving irrigation, and the use of permeable pavers. The project will not have a significant environmental impact as indicated by the proposed Negative Declaration for this project. The tennis court is proposed to be used during daylight hours only. Accordingly, the only light proposed is low-level lighting for the walking paths and the area under the pergola. 4. The use will be in accord with the Palo Alto Comprehensive Plan. Policy L-l of the 1998-2010 Palo Alto Comprehensive Plan encourages the City to retain undeveloped land west of Foothill Freeway and Junipero Serra as open space, with allowances made for very low-intensity development consistent with the open space character of the area. City of Palo Alto Page 5 The projeet site is west of the Foothill Freeway and is located within the City's Urban Service Area (map L-2 of the Comprehensive Plan). The Palo Alto Comprehensive Plan land use designation for the projcct site is Single Family Residential and one residence is permitted on each of the parcels of the projeet site. The proposed development's impervious coverage would be less than the maximum impervious area allowed for residential development of the subject property. The project does not include development of a house, but a recreational facility considered a residential accessory use. Because the subject lot does not have a residence on it, a conditional use permit is required for the new accessory use. The design is consistent and compatible with the Palo Alto Comprehensive Plan in that the design promotes Policy N-6, which states, "Through implementation of the Site and Design proeess and the Open Space zone dishict regulations, minimize impacts of any new development on views of the hillsides, on the open space character, and the natural ecology of the hillsides." The proposal is subject to the Site and Design Review process, complies with the applicable development standards and intent of the Open Space zone dishict, including the Open Space Criteria therein delived from policies in the Palo Alto Comprehensive Plan. Detailed analysis of conformance with the Open Space Criteria is incorporated into the Record of Land Use Action. POLICY IMPLICATIONS The project complies with the Comprehensive Plan and applicable Zoning Ordinance regulations as set forth in detail in lhe Draft Record of Land Use Action. Staff believes that the findings for approval of the Site and Design Review and Conditional Use Permit applications can be made. ENVIRONMENTAL REVIEW: An Initial Study and Draft Negative Declaration (Attachment B) have been prepared by staff, consistent with the requirements of the California Environmental Quality Act (CEQA). The CEQA documents were circulated September 2,2010 for a twenty day public comment period. The project was designed to be consistent with City zoning and Comprehensive Plan policies to avoid any significant environmental impacts. As of the wliting of this staff repOlt, no comments from the public or other agencies have been received regarding the environmental review. TIMELINE: A tentative consent calendar date for the City Council has been set for October 25,2010, subject to a favorable reeommendation by the Planning and Transportation Commission.

Environmental Assessment: An Initial Study has been prepared in accordance 12 with California Environmental Quality Act (CEQA) requirements. Zoning District: OS (Open 13 Space). 14 15 Ms. Elena Lee, Senior Planner: Thank you. The project before you, as you mentioned, is a Site 16 and Design Review and Conditional Use Permit to allow the new tennis court on a vacant lot for 17 the use of the property owner with residences on two adjacent lots. The property was a subject 18 of a previous Site and Design Review permit in 2008 to basically allow some landscaping 19 changes, minor additions, facade changes, as well as incorporation of 3208, the subject lot, into 20 this residential development under the same ownership. The third lot was approved to be 21 developed with a portion of the driveway and landscaping. No structures were approved on that 22 site. A Conditional Use Permit is required because the tennis court, which is typically an 23 accessory use, would be the primary use on an otherwise vacant lot. 24 25 'The proposal meets the maximum impervious coverage and all other development standards. An 26 Initial Study was prepared for the project, and a Negative Declaration was circulated on 27 September 2 for a 20-day review period that ended on September 22. As of today no comments 28 have been received on either the environmental clearance of the project, the only comment Staff 29 received was a phone call with the manager of the golf course who indicated he had no objection 30 to the project. Pending a successful recommendation by Commission a tentative date of October 31 25 has been identified for a City Conncil hearing. 32 33 The Planning Arborist, Dave Dockter, is supportive of the plans and the direction of the project. 34 He is available to answer questions tonight. Lester Hodgins of Community Services 35 Department, Supervisor of Foothills Park, confirmed that the City has no objection to the 36 proposal and it does not impact Foothills or Vista Point. If the Commission finds the project and 37 the Negative Declaration acceptable Staff recommends that you reconnnend that the Council 38 adopt the Negative Declaration and approve the proposed project. 39 40 Following the Staffs report the applicant will provide more detailed information on the project. 41 Additionally. the color materials sample board is available tonight over there for your review. 42 This concludes Staff's report, 43 44 Chair Tuma: Thanks very much. We will I think go ahead and go to the applicant. The 45 applicant has up to 15 minutes for presentation. You are not obliged to take it all but you do Page 1 I have that amount of time if you would like. Welcome. Please identify yourself for the record 2 please. 3 4 Mr. Dustin Moore, Suzman & Cole for the Applieant: I am (he Landscape Architect with 5 Suzman & Cole. On the site plan above the two lots to the south and to the west were previously 6 approved as described Elena. This is the third lot, which could be used as a single family home. 7 We want to use it as a tennis court with two sets of walls on the top and one wall on the bottom. 8 9 This was the original plan from 2007. You can see the third lot was originally considered to be 10 undeveloped. It is close to a three-to-one slope. These are two significant trees. Ifwe wanted to II develop this as a third parcel or a third home we would have to cut a driveway through this 12 space, which we do not. We just planted about 30 oak trces ranging in size from 36-inch box to 13 massivc. 14 15 This was the second submittal where we revised the pool. The pool is quite a bit larger in this 16 design. This was approved I believe close to a year ago or a year and t1u'ee or four months. I am 17 just trying to give you a history on the project. 18 19 This is current submittal. You can see the walls on top are somewhat significant. The larger one 20 is ten feet. This is four feet, and this is nine to ten feet in height. We have a small pergola 21 basically for viewing tennis. A regulation tennis court, a small storage structure that has an in 22 scale door, and a small kitchenette, which is a small refrigerator and sink, just for amenities to 23 the tennis court. 24 25 The planting is pretty restrained. It is predominantly California natives. We have a few exotics 26 like boxwood mainly because it is tough as nails and deer won't touch it. The rest of the plants 27 are California natives with the intent of blending into the landscape. 28 29 The concept below the tennis court, which this would be uphill and this is downhill. We are 30 going to plant a number of trees. I believe it is 25 or 30 trees. All different types of oak, we 31 have a handful of agri-folias. Our focus is on trees that will not be affected by sudden oak death, 32 which are additional hybrids including blue oak and a handful of other natives. Most of the 33 planting is pretty much adorning the trails and the actual structure. The rest of the landscape 34 would be hydro-seeded with the native seed mix that is approved for Arastradero Preserve and 35 Foothills Park. 36 37 Some of the elevations. This would be the tennis court looking back uphill. This is the 38 significant wall with a smaller wall to help break up the scale. We were planning on extensively 39 planting vines, a hedge at the bottom, so the end result in we are hoping five years but 40 realistically probably seven to tcn ycars would be that this is just a green wall and completely 41 blends into the surrounding. 42 43 We have two sections at the bottom showing the existing grade and then the proposed with the 44 tennis court, pergola, and walls. This would be the storage unit that is built into the hillside, the 45 ball machine, and any other pieces of equipment. 46 Page 2 1 The materials match the approved plan, which this shot shows all of different materials including 2 the flagstone that would be underneath the pergola. We are using a dark wood for the actual 3 structure of the pergola. This would be the ideal wall rock, which is shown on our materials 4 board. It is a limestone. This was the existing Cameron cut stone that is onsite that we are also 5 reusing. All of the paths on the third lot are gravel mainly to keep with the feel of the property. 6 We want to keep it trail-like or park-like. We also like the idea of it being penneable. 7 8 This aerial shows the current conditions before we started construction on the two properties, and 9 just showing kind of the character of the space. This is a current view from Foothills Park. As 10 you can see the entire property on the third lot is not visible. You could see the two massive oak II trees peaking up above the house but predominantly that property is not visible from Foothills 12 Park and is only visible from parts of Arastradero Preserve that are not accessible from the trail. 13 I did walk the trail trying to find a point where the site was visible just to make sure that we were 14 doing a photoshop visualization to show that we are trying to screen the property, but I could not 15 find that location. 16 17 This is a shot from the golf course looking back up to the property. This is the third lot. We 18 have a photoshop rendering showing the proposed walls and you can see that the siting of the 19 structure is so far downhill that most of it will be out of view. We are hoping within, granted the 20 oak trees are slow growing, probably within ten to 15 years having a pretty decent canopy at the 21 bottom of the slope. 22 23 I also threw in some specs for some of the lighting because there were questions from Planning 24 Staff about the lights. 25 26 A few other points I wanted to touch base with are the environmental issues. We are using a 27 slow release drainage system. It would be similar to a cistern where the water is pushed into 28 these large tanks, and there is a very small outlet or outfall. This makes the release of the water 29 over days rather than having this large piece of impervious pavement and just dumping that 30 down the hillside and causing erosion. This will slowly release the water into the pavement. 31 32 We are also using less development than what is allowed for the site, which would be a single 33 family home. This is just a recreation facility. I touched base on some of the native plants, 34 which are also low water use. We are not removing any trees onsite. We want to protect them. 35 36 Other parts of the overall site, or the three properties, we have a massive cistern system that has a 37 capacity of 140,000 gallons. To put it in perspective it could water a ball field for three or four 38 months. We also have a geothermal system. The whole house is cooled and heated by 39 geothermal, which is very low energy. The program for the property is just for private use. The 40 intent is not to have large gatherings or large events. There is absolutely no intent of a roof. The 41 idea is to have an open-air structure. I know that is part of another project that had some issues. 42 I think that is most of my comments and description. Thank you. 43 44 Chair TUlIla; Okay, great. I don't have any cards from members ofthe public. So I will open 45 and close the publie comment period and come back to Commissioners. r will remind everybody Page 3 I that this is a quasi-judicial item and so if they have any disclosures to be made let's not forget 2 that. I am looking for comments, question, or a motion. Commissioner Fineberg you are first. 3 4 Commissioner Fineberg: I have a few questions. First I will disclose that I did take a tour of the 5 site this morning. There were no significant conversations or learnings other than the site 6 manager being kind enough to show me where the courts were and point out a couple of 7 north/south directions. 8 9 One question I have on this project is the timing ofthe review and the approvals given that the 10 site is currently a large mound of steeply graded hare earth. If this moves forward what is the 11 timing for when it is going to go to Council, when work will be done, and is the site going to be 12 put to bed for the winter and then construction start in the spring, or somehow is this going to 13 move so quickly that there won't be erosion problems? 14 15 Ms. Lee: This item is tentatively scheduled for October 25 pending of course PTC 16 recommendation. In terms of construction it won't be able to happen until after October, but I 17 will leave that to the applicant to answer those. 18 19 Mr. Moore: I can answer that. Right now the schedule, we are trying to push along with the 20 permits because in the past we have had very long processes for this. The building permit will 21 take two to three months just to get through everything. The earliest that we would start 22 construction would be mid-April when we come out of moratorium. So there wouldn't be the 23 erosion control potential. 24 25 Commissioner Fineberg: Okay, so the protections for the bare steep slopes that are there now are 26 already in place with preexisting entitlements, and nothing that wc entitle now would then create 27 any issues. Wonderful, that is what I wanted to hear. 28 29 Another question for Staff. Is there anything about the building of the tennis court that would 30 require Building It Green checklist to be applied, or do we need to explicitly state thaI this is an 3 I exemption for the reasons that it could never qualify since there is no there there? 32 33 Ms. Lee: I consulted with Kristen our Green Building Planner and because there is no structure, 34 and because of the size of the project they don't trigger the requirement for green building. 35 Certainly we can request that they submit a checklist. I mean, consistent with the other 36 components of the project the applicant has been proposing fairly green practices. I am sure the 37 applicant can also provide additional information on that. 38 39 Commissioner Fineberg: I wouldn't necessarily advocate that they have to submit the checklist, 40 but ifit is intentional that there is no way to score the required points, and there is nothing that 41 triggers the Build It Green process I think it just needs to be explicitly stated as it moves forward 42 to Council that it is not a requirement because X, Y, Z. That way, it just doesn't come up as a 43 stumbling block. 44 45 Then on the site tour what I felt and saw was that once you are slightly downhill from the main 46 house, turnaround can't see Foothill Park, same as what Staff Report is saying. The one piece Page 4 I where I had a concern was the most immediate neighbor, a single family residence, and it looks 2 like it is just across Alexis Drive is going to be the closest to the courts and is visible to the 3 courts. So does Staff know, and I am sorry I don't know the address there. I stopped at the 4 mailbox and there was no number on it, but there is a giant Airstream parked in the driveway if 5 that is an identifying criterion for anyone. So has Stafftalked to that homeowner? Are they 6 aware that this project is happening? That is the one place where I would have a concern with 7 noise, and also if Dave Dockter, the Arborist, could tell us whether there has been particular 8 attention for plant screening since that is the closest neighbor with the best view. 9 10 Ms. Lee: We have not actually spoken directly to any of the property owners, but they should II have received notices and we have not recei ved anything from them. 12 13 Chair Tuma: It looks like the applicant maybe has something he wants to say. 14 15 Mr. Moore: Yes, I do. That particular neighbor we have been in contact with because we have 16 been trying to get them 10 clean up the property. On top of the Airstream he has three racecars 17 that he takes apart and rebuilds regularly. 18 19 We are planting Ihat whole side of the lot. You can see all of these oak trees. We have three oak 20 trees that are fairly massive right now. We just put in a massive row of poplars. I can guarantee 21 you within three years you won't be able to see that house. We made a point to screen that house 22 from our property because we are tired of looking at the Airstream. So in answer, he won't be 23 able to see it. There is also saddle in that portion of the property and we sited the tennis court in 24 that location just to take advantage of that to where it does tip in. The idea was to avoid any 25 views into that property while the trees are filling in. So we have covered that. 26 27 Commissioner Fineberg: Can Ijust finish on that? Is the City Arborist comfortable that that's 28 your perception of the planting plans also? 29 30 Mr. Dave Dockter, Planning Arborist: Yes. I feel that the screening will definitely become more 31 and more apparent, especially with the oak trees beneath the large oaks. I have not gone over to 32 the neighbors specifically and looked over from their vantage point. The rest of the property 33 from the large oaks to the edge is fully treed. So it is going to be a substantial green screen. I 34 feel comfortable that that whole section along Alexis will be satisfactorily screened. 35 36 Commissioner Fineberg: Thank you. I have one more issue if you want me to cede time or just 37 finish up? Okay. For conditions of approval, we had talked about this in the pre-Commission 38 meeting, and I am not sure ifit is in there and I missed it. Is it worth including a statement in the 39 conditions of approval that explicitly states that the recreational use is for private residential 40 recreational use and rule out commercial or public recreational uses? Has that been captured and 41 would Staff consider that a good addition? Then also the same question for whether or not to 42 include a prohibition on any kind of future roof or enclosed structure. 43 44 Ms. Lee: In terms of the Record of Land Use Action in the CUP findings it actually states that 45 this is a private recreational use and nol a commercial recreational use, but we can also 46 incorporate into the conditions of approval that the tennis court is for the property owner and Page 5 I residents of 3230 and 3220 Alexis Drive and their guests. Then we can also incorporate that the 2 court shall remain umoofed. Since this is a Conditional Use Pennit we can certainly be more 3 specific. 4 5 Commissioner Fineberg: I think those would be good additions in the condition section. Thank 6 you. 7 8 Chair Tuma: Commissioner Garber. 9 10 Commissioner Garber: I am prepared to make a motion but 1 want to mnke sure that if there are II other questions by any of the Commissioners that they have an opportunity to do that. So why 12 don't I wait until other questions have been asked and answered. 13 14 Chair Tuma: Okay. Commissioner Martinez. 15 16 Commissioner Martinez: To the applicant, do you have a slide of the cross-section through the 17 tennis court? 18 19 Mr. Moore: I do. The two sections are on the bottom. They are kind of faint but you can see the 20 existing grade. 21 22 Commissioner Martinez: On the drawings we got you didn't indicate what the grades were, what 23 the elevations were at the top of the cut and the bottom. Can you tell us what those are? 24 25 Mr. Moore: There should have been a grading plan. Do you have hardcopies? 26 27 Cl}air Tuma: I believe it is L-7.2. 28 29 Mr. Moore: Yes, 7.2 is the grading plan. 30 3 I Commissioner Martinez: Okay. What are those elevations then? 32 33 Mr. Moore: The very top wall would be 783.75. The top of the second wall moving down 34 would be 777.5. Then the top of wall at the bottom .... 35 36 Commissioner Martinez: Actually, I am interested in the top on the topography of the existing 37 grade from the top ofthe cut to the bottom, not the walls themselves. 38 39 Mr. Moore: Okay. At the largest wall the cut would be approximately 12 to 13 feet. 40 41 Commissioner Martinez: What is the elevation -not the elevation of the wall, of the ground? 42 43 Mr. Moore: So I am interpolating from, so this very top wall is at grade. I am talking this wall 44 and going upward so I am interpolating that it would be around 780 flat, and our grade at the 45 court would be 767 flat, which would be 13 feet. 46 Page 6 I Commissioner Martinez: So at that point where you light is now .... 2 3 Mr. Moore: That is where it breaks. 4 5 Commissioner Martinez: That is at 7-what did you say? 6 7 Mr. Moore: That would be 767 where the court ~ basically this is where cut and fill. This side is 8 fill and this side is cut. Then on the inverse section this is entirely cut and it is approximately 13 9 to 14 feet 0 f cut at its greatest. 10 II Commissioner Martinez: That is where the 2,000 cubic yards of cut come from? 12 13 Mr. Moore: Correct. The reason for that was wc wanted to cut much more than to fill otherwise 14 we end up with massive walls, and it also makes it mueh more visible from offsite. 15 16 Commissioner Martinez: Where does that extra earth go? 17 18 Mr. Moore: To be truthful we will try to trade that with other contractors to balance cut and fill. 19 If we cannot find that it will go to Steven's Creek qualTy, which is a landfill that accepts spoils. 20 21 Commissioner Martinez: Okay, thank you. A question for Staff. Isn't there something in the 22 Comprehensive Plan that talks about not taking residential uses out of ..... am I making that up? 23 That if we have a residential lot you can't turn it into something else? 24 25 Ms. Amy French, Current Planning Manager: Are you thinking of the Open Space District or 26 just in general? 27 28 Commissioner Martinez: I have been reading the Comprehensive Plan a lot so I am mixing 29 things up. 30 31 Ms. Caporgno: We are going to look for it. I am unaware ofit. You maybe reading it a lot more 32 than most of us so you might be able to tell us, but we will search through it. 33 34 Commissioner Martinez: Okay, that's fine. Thank you. 35 36 Chair Tuma: Commissioner Garber, I think you are up. 37 38 MOTION 39 40 Commissioner Garber: I would like to move that the Planning Commission accepts the Staffs 41 recommendation that the City Council adopt the Negative Declaration and approve the Record of 42 Land Use Action approving the request for Site and Design Review and a Conditional Use 43 Permit to allow development of the private recreational facility on this parcel, and that the 44 Commission finds that the project is in compliance with the Open Space criteria and that the 45 project meets the Site and Design Review findings. I would also like to add that we call out that 46 the project does not require a Grecn Points Rating and I will save the rest of it for my comments. Page 7 I 2 SECOND 3 4 Vice-Chair Lippert: Second, 5 6 Chair Tuma: So that is a motion by Commissioner Garber, seconded by Vice-Chair Lippert. 7 Commissioner Garber, you wish to speak to your motion? 8 9 Commissioner Garber: Yes. I will note that -I was going to ask the question but it was actually 10 made explicit when I reread the Staff comments there that there are no tennis lights, There are 11 just simply foot lights, and that it is for private use, and that the project is not visible from 12 Foothills Park, which was in my mind the largest concerning issue. Other than that I believe it is 13 a project that meets the Comprehensive Plan short of any notice by our Staff and they are 14 searching through the pages of the Comprehensive Plan over there, I will leave it at that. 15 16 Chair Tuma: Vice-Chair Lippert, would you like to speak to your second? 17 18 Vice-Chair Lippert: Yes, This is probably the third maybe the fourth time I have seen this 19 project. Actually I believe the first time I saw it was when I was on the Architectural Review 20 Board, and because it was three parcels it was subject to ARB review at the time. It was 21 supposed to be developed as I think three separate houses. Do you want to correct me? 22 23 Ms. French: The reason it came to the ARB at the time was because at the time our code said 24 two or more houses under the same ownership must go through ARB review. That was later 25 revised to threc or more homes. 26 27 Vice-Chair Lippert: Right, yes. Well, the reason why it came forward was because it was 28 developed as multiple houses so it was considered to be a tract developmcnt basically. Atthe 29 time it was quite unfortunate, it was the Goldman residence, and at the time he was a leader in 30 sustainabilityand it was actually built or designed to be a sustainable house. At that point, 31 before we had any sort of green point system or LEED there were a number of sustainability 32 features in and green features that were built into the project. Fortunately enough John 33 Chambers who then purchased the property saw the great wisdom to not only keep a lot of the 34 green features, but in addition to that built upon that with significant amounts ofiandseaping 35 greening up the project even more. So as far as a sustainability project this project probably 36 exceeds any green project in Palo Alto to date, if in fact all those criteria. 37 38 Getting to the actual approval that we are doing today, or the recommendation that we are doing 39 today, this is a rather benign use for that lot. I would much rather see a tennis court on that 40 parcel than another residence. So I think that they have been very sensitive in tenus of the 41 placement of that tennis court, the screening of the tennis court, as well as the additional features 42 of additional mature trees in tenus of screening the tennis court, and the fact that it is only going 43 to be used for private use, and that it is going to have a very low intensification in tenus of use. I 44 think it is a great project. I don't see any reason to deny them a use that other people can get on 45 their own parcels regarding recreational uses in the Open Space. So I support the project fully. 46 Page 8 I Chair Tuma: Okay. Commissioner Martinez. 2 3 Commissioner Martinez: It looks like I am going to be the only one offering a protest vote on 4 this. I would have thought that, and I still want to believe that the residence of the Open Space 5 District care more about the land than about having sort of all the creature comforts one could 6 imagine in proximity to their house. I think that we have seen since I have been on the 7 Commission three items in the Open Space District that address in some manner how we see the 8 importance of the district and how we want to preserve our natural resources. 9 10 The first one was the maximum house size issue. The Commission felt that a 15,000 square foot 11 house made sense to be built in the Open Space District. The second was the recent ice rink that 12 the Commission felt was a good idea for a single-family residence to have in the district. Now 13 we have this 8,000 square foot recreation center that we will soon feel is okay to be in the Open 14 Space District. It is just confounding to me that we can debate for hours over moving a liquor 15 store 50 feet in order to preserve a grocery store, but what we do to the land means nothing as 16 long as we comply with the Comprehensive Plan, and its so-called sustainable, and no one can 17 see it. 18 19 Well we are eutting, we the community, is allowing cutting this 13 foot hole in the earth to allow 20 for a tennis court. Now it seems to me we need to look inward, not necessarily that this applicant 21 is doing anything that they are not able to do or allowed to do, but is this the way we want to 22 preserve the earth? This kind of cutting and forming the earth into whatever we want it to be. A 23 tennis court is fine but what it leaves on the ground I just can't believe that that is okay. That we 24 get in the Open Space a proposed use that doesn't seem to be back to nature, or living with 25 nature, or how much we care about nature and the environment or open space. It is just an 26 incongruent use on our natural resources. So I am going to vote in the minority not to support 27 this application. 28 29 Chair Tuma: Commissioner Garber and then Fineberg. 30 31 Commissioner Garber: I would just like to state how much I respect Commissioner Martinez's 32 comments and him as a Commissioner. I appreciate the comments that he has made this 33 evening. I would encourage him to change his vote, not that I expect him to do so, because as 34 stated there isn't anything that the project does that is outside of what is allowable. 35 36 I would also caution you about presupposing what other homeowners in the Open Space District, 37 the impressions, or the understandings of the use of the land, and what they have. Commissioner 38 Tuma and I have spent some time with a number of the members up there as part of the 39 subcommittee and I think you would be very surprised by what they believe they should be 40 allowed to do, which isn't necessarily what is allowable under the eodes and zoning. It is often 41 in great contrast to what as they refer to us the 'flatlanders' believe should be done with that 42 open space. All that said, I respect the comments and am moved just to thank you for them 43 regardless if you end up in the majority or the minority of the vote. 44 45 Chair Tuma: Commissioner Fineberg. 46 Page 9 I Commissioner Fineberg: I think my feelings on this projeet straddle the fence. I have mixed 2 feelings that frankly there is nothing green or sustainable or environmentally sound about 3 building a private tennis court. But I don't get to make that decision. There are rules and 4 entitlements and rights that landowners have, and guidance that we get from within the 5 Comprehensive Plan, from within Municipal Code and that is what I need to follow. 6 7 I am looking at the Vision Statement in Chapter 5 of our Comprehensive Plan, Natural 8 Environment. It talks about Palo Alto will respect and manage natural resources in a way that 9 sustains the natural environment, and proteets our foothills, Baylands, creeks, parks, wildlife, and 10 open space legacy. Elements of the natural environment will be conserved where they remain in II tact, and restored where they have become degraded by past development. Without casting 12 aspersions the parcels that are combined to make this project have been degraded by past 13 development. They are not virgin, pristine, open space as is adjacent beyond the fence. So that 14 makes me less concerned, less worried about taking away pristine open space. 15 16 If the court is to get built I believe that the way it is being built honors the spirit of the 17 Comprehensive Plan. Comprehensive Plan says cut is to be favored and fill minimized and it 18 does that. It is not visible from the City parklands. The fact that the previous development on 19 the project was, ship sailed already. So being left with the idea ofless would be better I don't get 20 to make that deeision. I don't feel I do. So I will be inclined to support this. I would like to ask 21 the maker and seconder if they would consider two friendly amendments that I mentioned 22 earlier. The language that Elena had noted before regarding the conditions of approval including 23 the language that it be specifically for residential, private recreational use, not commercial, and 24 that there be prohibitions on future roof or enclosing structures. 25 26 Commissioner Garber: Future, I am sorry what? 27 28 Commissioner Fineberg: I would want Staff to workout the language, but that there be a 29 prohibition that it not include a future roof or becoming an enclosed structure. 30 31 Commissioner Garber: Both are fine with me. Seconder? 32 33 Vice-Chair Lippert: T don't have a problem with either of those two friendly amendments. I 34 think that what could be a bit problematic is that I don't think we can put a prohibition on the 35 roof structure. If somebody came back to us with an application and said that they wanted to put 36 a roof structure on it they would have to go through Site and Design Review again, correct? 37 38 Mr. Donald Larkin, Assistant City Attorney: Yes, we would create a condition that says they 39 can't do it as part of this CUP. If at some point in the future ifthc applicant wanted to come 40 forward with a new CUP and a new Site and Design Review it would go through that review. 41 42 Chair Tuma: Okay. I have just one comment, concern, or question. I just want to make sure 43 that the documentation makes it abundantly clear that what we are approving here is a tennis 44 court and not a recreational facility. I have heard those terms used interchangeably this evening. 45 I am not sure that the document specifically says that the use would be limited to a tennis court 46 and things associated with a tennis eourt. I don't know exactly how to say it, but I want to make Page 10 I sure either the documents already say it or I would offer a friendly amendment to the motion that 2 says that it is limited to a tennis court and it is not a broader recreational facility. 3 4 Ms. French: Could I read a condition that I have been writing with the acceptance of the 5 amendment? Condition 3 to be amended, the tennis court shall be used during daylight hours, 6 only as a tennis court for private use by the property owners and residents at 3220 and 3230 7 Alexis. Followed by the sentence, "Alexis lighting to facilitate nighttime play is not allowed, 8 and the court shall remain unroofed and unenclosed." Does that cover? 9 10 Commissioner Fineberg: I am not sure if I missed it but earlier I think Elena had said the II residents and guests, did you capture guests? 12 13 Ms. French: Sure, I have 'and their guests' in parentheses in that sentence to add. 14 15 Chair Tuma: Elena. 16 17 Ms. Lee: Thank you. I just want to clarify that the Record of Land Use Action does refer 18 specifically to a tennis court. When it references recreational facility in parentheses next to it is 19 'tennis court.' So it is pretty clear but we can certainly go through it to make sure that we use 20 tennis court rather than recreational facility. 21 22 Chair Tuma: Yes, my point is that it needs to be limited, because sometimes if you say 23 recreational facility (tennis court) that could be interpreted a number of different ways. I think 24 we need to say that it is limited to being a tennis court. So at this point I would offer the 25 language that Amy proposed as a friendly amendment to sort of clean up the friendly 26 amendments and the motion if that is acceptable to the maker and the seconder. 27 28 Commissioner Garber: It is. I will note that on page I of Attachment A it is referred to as 29 recreational facility. 30 3 I Chair Tuma: Seconder? 32 33 Vice-Chair Lippert: Yes, that is agreeable with me as well. 34 35 Chair Tuma: Commissioner Keller. 36 37 Commissioner Keller: Okay, since we are wordsmithing I would suggest that the wording that 38 Amy proposed that the first part of that actually read not the tennis court is to be used for tennis 39 but that the recreational facility is limited to use as a tennis court, etc. Because that deals with 40 the potential gap between the tennis court and other areas within the recreational facility, and I 41 think that tightens everything and solves the problem. So let me offer that as yet another friendly 42 amendment, and then I will have a couple of comments beyond that. 43 44 Commissioner Garber: Sure, done. 45 46 Vice-Chair Lippert: No problem. Page II I 2 Chair Tuma: Go ahead. 3 4 Commissioner Keller: I think that I don't have any particular judgment as to whether people in 5 Open Space should or should not have tennis courts on their land. That is no! something I really 6 wish to weigh in on. I do observe that the alternative to this tennis court is the potential for 7 another house. A house in this location would have more impacts on the land than a tennis court 8 is likely to have. So I think the tennis court is much more likely, especially considering how it is 9 going to be screened, and I doubt that a house would be screened as equally nicely. So I think 10 this actually respects the land more than another house would. 11 12 With respect to the issue as to whether there is some sort of notion in the Comprehensive Plan of 13 not replacing houses with non-houses or something like that there is not a house there now. So 14 we are not reducing the number of housing units. On the other hand, there have been a number 15 ofteardowns in Old Palo Alto, some of those houses were historic, or at least of long age that are 16 much more of an issue because that actually reduces housing stock. This simply doesn't add one 17 to the mix and I think that from my point of view is different from actually tearing down an 18 existing house. So I will vote in favor of this motion. 19 20 Chair Tmna: Vice-Chair Lippert. 21 22 Vice-Chair Lippert: I would like to make one final comment. Again, I would like to second 23 Commissioner Garber's comment earlier to Commissioner Martinez. I respect your position on 24 this project and would hope that you could support it for a varicty of other reasons. \Vhen the 25 Open Space District was conceived the property owners or the developer at the time paid how 26 shall I say it, the freight up front. What they actually had done is when the subdivision happened 27 a significant number of acres were actually donated to the Arastradero Preserve. In doing so 28 those lots became somewhat reduced in their size. With regard to this particular project, again 29 the tennis court is a rather benign use when you compare it to the impacts of a house. 30 Considering that the three parcels have been developed together and that the property owners and 31 the subsequent property owners actually went and greened up each of the sites individually 32 adding other sustainable features to it, it actually begins to approach almost a non-impact site 33 with regard to the tennis court itself. So while again I think that the tennis court represents a 34 minor impact on the site it is preferable to having another house there. I think that was very 35 clearly said by Commissioner Keller. So again I would encourage Commissioner Martinez to 36 support the project on thaI basis, because we could have a house on that property. 37 38 Chair Tuma: Staff, Julie did you have something you wanted to say? 39 40 Ms. Caporgno: Yes. I just want to confirn1 that we couldn't find anything in either the Open 41 Space Chapter or the Land Use Chapter. I know there is nothing in the Housing Chapter that 42 pertains to that. 43 44 Chair Tuma: One second, Commissioner Martinez on the mike if you could. 45 46 Commissioner Martinez: Policy H-S. Page 12 1 2 Ms. Caporgno: We don't have the Housing Element in front of us. Could you read it to us? We 3 looked at Open Space and Land Use. 4 5 commissioner Fineberg: Policy H-5, it is on page 19 of 41 in the Housing Element. It says, 6 "Discourage the conversion oflands designated as residential to nonresidential uses and the use 7 of multifamily residential lands by nonresidential uses such as schools and churches unless there 8 is no net loss of housing potential on a community wide basis." 9 10 Ms. Caporgno: That policy was specifically developed so that we wouldn't lose residential II development to churches, etc., but I don't think there the intent was for a site that didn't include 12 any sort of development, and particularly multifanlily development. I think it is in the 13 multifamily section that that pertains to. Again, I don't have the Housing Element in front of me 14 but that's my recollection. 15 16 Chair Tuma: while you look at that the applicant is entitled to a three minute. Counsel, do you 17 have something? 18 19 Mr. Larkin: I was just going to add that the program that implements that policy does say that 20 part of the Zoning Ordinance Update process would be to change the zoning code to disallow 21 uses other than residential uses in the multifamily residential zones, not specifically to the Open 22 Space. 23 24 Chair Tuma: Okay, thanks for that clarification. You have up to three minutes if you would 25 like. 26 27 Mr. Moore: I have a few comments to hit on some of your comments. One is the housing code. 28 There is a small portion of the lot that could be developed into a one-bedroom apartment. So 29 there could be one unit put on the property, although we have absolutely no intention of doing it. 30 So there still is the potential to build a unit on that property. The whole reason the client bought 31 this property is to make sure that it is never developed. It would interfere with the view on the 32 other two lots and that was his entire drive to purchase this property. 33 34 Also, to hit on the reason for having the tennis court. He has a lot of security issues and he has a 35 tennis court at his current home, and he wants to have the same thing. On other properties in the 36 Open Space you could not develop a tennis court just for the coverage numbers. You are 37 allowed to have 15,000 square feet of coverage and a tennis COUll is about 8,000 square feel. 38 39 The way that it is designed currently it could never be roofed just because of height restrictions. 40 It would be over the 27-foot maximum. 41 42 I would also like to confirm that we will use as many green technologies as we can with fly ash 43 in the concrete. We have many other ways that we are trying to make it more green. I do 44 understand your concerns. Those are all my comments. 45 46 MOTION PASSED (6-1-0-0, Commissioner Martinez opposed) Page 13 1 2 Chair Tuma: Okay. With that I will close the public hearing and bring it back to the 3 Commission for a vote. Does anybody feel the need for the motion to be restated? Okay. So we 4 will go ahcad and vote. All those in favor please indicate by saying aye. (ayes) Opposed? 5 (nay) The motion passes on a six to one vote with Commissioner Martinez voting no. With that 6 we will close that item. 7 Page 14 April 29, 2010 Amy French ATTACHMENT" Submitted by Applicant Palo Alto Planning and Community Environment 250 Hamilton Avenue, 5'h Floor Palo Alto, CA 94301 Re: 3208 Alexis Drive Leiter of Application Hello, The proposed project for 3208 Alexis Drive is to include a tennis court, associated fencing, retaining walls, guardrails, outdoor counter with sink and a small storage area built into the hill and retaining wall, The use of the development is an accessory structure to 3230 and 3220 Alexis Drive and does not have a primary dwelling unit. The use of the structure is for recreation, The tennis court is to be cut into the hillside to help mitigate views to the property from Palo Alto Hills Golf and Country Club, There are no views to the proposed improvements from Foothills Park, The retaining walls have been designed to cut more than fill to minimize the appearance from off site, The walls will be clad with limestone and have vine plantings to soften the appearance of the walls, The improvements are of sound environmental design and ecological balance, The proposed design uses less energy and resources than siting a new residence and maintains the eastern hillside as undeveloped with new oak tree plantings, The proposed site design uses 59% of the allowable impermeable coverage and retains all existing trees, The proposed improvements along with previously approved improvements will add 45 trees to the property, The proposed planting is predominantly native with a few adaptive and drought tolerant plants, The following addresses the Open Space District Criteria as described in section 18.28,070(pj of the Palo Alto Municipal Code: 1, The development is cut into the hillside to minimize the visual impact from Palo Alto Hills Golf and Country Club, There are no views to the improvements from Foothills Park, 2. The retaining walls have been located as close to the Northem setback to bring the developed area as for downhill as possible, The ridgeline is not affected with the proposed improvements. 3, The development is cut into the hillside to minimize the visual impacl from Palo Alto Hills Golf and Country Club. There are no views of the proposed improvements from foothills Park, Landscape Architectufe 1265 Battery Street, 5" Floor San Francisco, CA 94111 Main 415.252.0111 Fax 415.861.6163 www.suzmnncole.com 4. The vast majority of developed area is clustered around the tennis court. The remainder of the site is trails and planting with minimal impact. The planting is predominantly native with a few adaptive plants. 5. The retaining walls have been designed to closely follow the existing contours to minimize wall heights and fit the existing topography. All plantings are to have a natural appearance in form and use native and adaptive plants. 6. All existing trees are to be retained and protected. 7. The proposed improvements utilize a 75% cut to 25% fill proportion to help minimize the visual impacl to adjacent properties. 8. The tennis court is a large flat expanse, but we will be retaining storm run off wilh a slow release system to reduce Ihe amount of run off. 9. The material for all walls is limestone in a beige tone. The color is selected to blend into the hillside. The hillside is predominantly grasses that turn gold in summer and fall. The walls will be covered with vines to further soften the appearance of the walls. 10. The planting is predominantly native with a few adoptive and drought lolerant plants. 11. All exterior lighting will be low voltage and be kept to a minimum. The lighting will be for safety purposes on pathways. The tennis court will receive lighting only for safety purposes and will not have athletic lighting. 12. The improvements do not include a driveway or road. All access is to be from 3230 and 3220 Alexis Drive. Parking is situated on both properties for use of the tennis court.

Instead of developing a single family residence, a series of retaining walls and a tennis court are planned to be built. There is less strain on public utilities, less energy consumption and the hillside fronting Alexis Drive will be left undisturbed, The improvements are not visible from Alexis Drive or Foothills Pork, The improvements will be visible from Polo Alto Hills Country Club, but the siting of retaining walls and cutting into the hillside will help hide the improvements. In addition, several trees will be planted to help screen the improvements in the future. The improvements will not be detrimental to public health safety, welfare or convenience. The upper retaining walls will have guardrails to prevent a fall hazard and the tennis court will be surrounded by fencing. In addition, the site is surrounded by a previously approved six foot tail fence to prevent others from reaching access to the improVements and is scheduled for installation in fall of 201 0, The location of improvements does not pose a threat to the slope or existing trees. All existing trees will be protected per Palo Alto code and be monitored by the project arboris!. The siting also screens the improvements from Foothills Park and Alexis drive to reduce public visibility. The earthwork spoils will be disposed at Stevens Creek Quarry in Cupertino, CA. Imported topsoil will also be provided from Stevens Creek Quarry in Cupertino.
