HomeMy WebLinkAboutItem 3.13.1 Town of Los Altos Hills April 3, 2008 Staff Report to the Planning Commission RE: PROPOSED AMENDMENTS TO THE GENERAL PLAN INCLUDING UPDATED LAND USE AND PATHWAYS ELEMENTS WITH INITIAL STUDY AND NEGATIVE DECLARATION FROM: Leslie Hopper, AICP, Project Planner 4-+ APPROVED BY: Debbie Pedro, AICP, Planning Director -i -IR RECOMMENDATION That the Planning Commission: Review the proposed amendments to the General Plan and the proposed Initial Study/Negative Declaration and consider comments from the public. 2. Make a recommendation to the City Council to approve the Initial Study/Negative Declaration and adopt the proposed amendments to the General Plan with any modifications deemed appropriate. BACKGROUND In July 2005 the City Council established the Ad Hoc General Plan Committee and authorized it to begin updating the General Plan. The broad-based Committee has six members, including a member of the City Council and a member of the Planning Commission. The Committee has been meeting twice a month to update six of the nine existing elements of the Town's General Plan. The project was divided into three phases: • Phase 1—Introduction, Conservation Element, and Open Space & Recreation Element • Phase 2—Noise and Safety Elements • Phase 3—Land Use and Pathways Elements The City Council approved and adopted Phase 1 on April 26, 2007 and Phase 2 on November 8, 2002 Phase 3 is currently under review, and adoption of the updated Land Use and Pathways Elements will complete the General Plan update project. THE GENERAL PLAN The General Plan is the Town's blueprint for the future. It provides policy direction for land use decisions regarding the conservation of resources and the development of the community. Sometimes described as a local constitution, the General Plan provides a legal foundation for zoning, site development and subdivision ordinances, all of which must be consistent with the General Plan. State law requires the General Plan to include at least seven elements: Land Use, Planning Commission April 3, 2008 Page 2 of 3 Housing, Circulation, Conservation, Open Space, Noise, and Safety. Other elements such as Recreation and Pathways are optional. STATE REQUIREMENTS State law requires the Housing Element to be updated every five years, and the Governor's Office of Planning and Research (OPR) recommends that the other elements be updated every eight to ten years. The existing Land Use Element was adopted in 1975 and has not been comprehensively updated since that time. The existing Pathways Element was adopted in 1996. UPDATE PROCESS The General Plan Committee reviewed the existing Land Use and Pathways Elements to correct errors, inaccuracies and obsolete references. The format was updated to produce more accurate, legible and reproducible documents, including improved graphics that accurately depict existing conditions in the Town. In addition, the goals, policies and programs were reviewed to ensure that they were relevant and appropriate. PARTICIPATION BY OTHERS Draft documents were distributed to the following committees and agencies for review and comment: • Open Space Committee • Environmental Design and Protection Committee • Pathways Committee • Parks and Recreation Committee • Public Education Committee • Environmental Initiatives Committee • Purissima Hills Water District • Cal Water Service Company The General Plan Committee reviewed the comments received and made appropriate changes to the draft documents. KEY POLICIES AND PROGRAMS Most of the policies and programs in the updated Land Use and Pathways Elements are already included in the existing General Plan or have been added to reflect current practices. Key policies and programs are highlighted in yellow in the text of the documents. In addition, they are summarized in Attachment 3. In most cases, these policies and programs reflect the Town's current practice. The policy and programs related to green building practices are entirely new. AMENDMENT TO OPEN SPACE & RECREATION ELEMENT Under California Planning and Zoning Law, the General Plan must be internally consistent, with no conflicts or inconsistencies between elements. In order to correct an inconsistency between Planning Commission April 3, 2008 Page 3 of 3 the proposed Land Use Element and the newly adopted Open Space & Recreation Element, the following minor amendment is proposed: "Steep canyons and creek corridors that should be protected are designated as Open Space Conservation Areas on the Land Use Diagram. Develeprnertf in these weas is ge�ffalb, a . _fo_,,.,d _...�...... .. r � allowed. Within these areas, special measures should be taken to conserve the natural quality of the area and to avoid environmental degradation Residences should be placed on the most buildable Portions of lands desismated OSCA and carefully sited so as to preserve existiniz trees veaetafaon and wildlife habitat In addition to canyons and creek corridors, visually important open space lands associated with major religious and educational institutionally facilities or are designated Open Space Conservation Areas." The amendment will change the statement regarding Open Space Conservation Areas on page 8 of the Open Space & Recreation Element (included as Attachment 4) to be consistent with the updated Land Use Element. PUBLIC NOTICE A Townwide notice was mailed more than ten days prior to the Planning Commission hearing pursuant to LAH Municipal Code Section 10-1.1105. In addition, Notice of Intent to Adopt a Negative Declaration was published in the Town Crier and posted in the County Clerk's Office as required by state law. The review period for the Negative Declaration is April 2—May 8, 2008. ENVIRONMENTAL REVIEW In compliance with the California Environmental Quality Act (CEQA), an Initial Study was prepared and a Negative Declaration is proposed for the project. The proposed amendments are intended to fine-tune and strengthen existing policies and programs that preserve the Town's semi -rural, residential character, protect its natural areas, provide for orderly growth and extension of public services, and implement the pathways system. New policies and programs me intended to provide additional environmental protection. No adverse environmental impacts will result from adoption of the proposed General Plan amendments. COMMENTS RECEIVED No comments have been received to date. ATTACHMENTS 1. Updated Land Use Element 2. Updated Pathways Element 3. Summary of Key Policies and Programs 4.

Los Altos Hills is a residential community nestled in the scenic foothills of the Santa Cruz Mountains. Once a rural agricultural area, the community has become one of the premier residential areas in Silicon Valley. Over the years, the population has grown and land use patterns have changed. The farmhouses, cattle ranches and orchards of the past have become today's private homes, riding stables and vineyards. The community has gradually urbanized over time but still retains a semi -rural atmosphere, with large lots and expanses of open space as envisioned by the Town's founders. We want the sun and air and quiet of a community which has given itself enough space to breathe in; the relaxed pace of country life and rural pursuits. From the Green Sheets published to 1956 pnor to the Town's incorporation. 102. Like their forefathers, today's residents value the semi -rural character of the community. Although it is nearly fully developed, the community is still evolving. Decisions the Town makes today can change the way the community will look, feel and function in the future. The guiding principle of the Land Use Element, as with other parts of the General Plan, is to address long-term needs while preserving the semi-mral character of the community and the overall quality of life for residents of Los Altos Hills, Scope 103. This element addresses the factors that contribute to preserving community character including the protection of its natural setting, the maintenance and improvement of its residential neighborhoods, and the provision of quality public services and facilities. This element also helps define the desired balance among the social, environmental and economic costs and benefits associated with development Relationship to Other Elements 104. The Land Use Element is the keystone of the General Plan. It unifies the other elements by providing an overall policy context. Many subjects reviewed here are discussed in greater detail in other elements such as the Circulation & Scenic Roadways Element, the Pathways Element, Housing Element, Conservation Element, and Open Space & Recreation Element. State Requirements 105. This element meets the State -mandated requirements for a Land Use Element. It defines the Town's land use categories and includes a Land Use Diagram that designates the land use category of each parcel in the planning area. It also includes standards of population density and building intensity for various land use categories. The Land Use Diagram and the goals, policies and programs in this element will determine the location, intensity and design of new development and ensure that the community's semi -rural character is maintained. Land Use Element Los Altos Hills General Plan Page I Public Review Draft 3/24/08 LAND USE PATTERNS History of Develooment 106. After World War 11, the pressures of a growing population and increasing urbanization were felt throughout the San Francisco Peninsula. Many members of the unincorporated Los Altos Hills community viewed local commercialism as undesirable and felt threatened by possible annexation by neighboring cities. When adjacent Los Altos incorporated in 1952 with a one -quarter -acre minimum lot size, residents of the Hills knew they had to take action to defend and preserve the amenities of their rural life, such as one -acre lots and the right to keep horses on private property. 107. The compelling reasons for the incorporation of Los Altos Hills were printed on green paper and distributed to residents in the fall of 1955. As stated in this document (referred to as the "Green Sheets") one of the primary reasons the founders of the Town originally decided to incorporate in 1956 was to maintain the rural character of the community. This desire continues today. 108. Existing land Use The Town is unique in that it consists mainly of low-density single-family residential development, with a minimum lot size of at least one acre. There are no commercial or industrial uses within the city limits. As the From the Green Streets -19W What Kind of Community Do We Want? ... a wide and not overpopulated community of homes in the country.. . ... the space and right to keep animals—rabbits, chickens, dogs, sheep, cattle and horses... Town has developed over the past 50 years, residents have continued to support the preservation of low-density residential development and the semi -rural character of the community through one -acre zoning and the protection of open space, creek corridors, wildlife habitat and heritage oak trees. 109. The only non-residential uses within the Town are open space, parks and recreation facilities, a unique pathways system including miles of well-maintained roadside and off- road paths, and public and private institutions such as schools, churches and governmental buildings. Current Trends 110. With limited land available for additional housing and only slight possibility of change on non-residential parcels, Los Altos Hills is almost fully developed. However, in addition to infill development on vacant lots, redevelopment is occurring as existing residences are torn down and replaced with new homes. The current trend is to develop residences that maximize the square footage allowed under floor area and development area regulations established by the Town's Zoning Ordinance. Land Use Element Los Altos Hills General Plan Page 2 Public Review Draft 3/24/08 Population Projections 111. In Projections 2007, the Association of Bay Area Governments (ABAG) forecasts that the Town's population within its corporate limits will increase from 8,500 in 2005 to 9,400 in 2035. The number of households is predicted to increase from 2,960 in 2005 to 3,300 in 2035 based on an average household size of 2.8 persons. However, these projections appear to be unrealistically high considering the availability of land and the development potential of the community. Development Potential 112. A study of vacant and undemtilized parcels conducted for the 2002 Housing Element identified a total of 138 vacant parcels with the potential to be subdivided. Based on the size of the lots and known development constraints such as steep slopes and open space designations, it was estimated that approximately 58 to 176 additional units could be developed through subdivision of these parcels. At an average of 2.8 persons per household, development of 176 additional units would result in a maximum population increase of 493, putting the total population at build -out at 9,100 compared to ABAG's projection of 9,400 in 2035. Although additional households could be accommodated through the development of secondary units, it is not realistic to expect the Town's population to increase significantly beyond 9,000. Implementing the General Plan The Town's population is not expected to increase significantly due to limited land available for residential development. The Town's Zoning Ordinance, Site Development Ordinance and Subdivision Ordinance are the main tools used to implement the General Plan. Supported by administrative policies and procedures, the ordinances establish processes for review and approval of proposed land uses and regulation of site development. The General Plan is also implemented through specific programs that accompany the goals and policies. Land Use Element Los Altos Hills General Plan Page 3 Public Review Draft 3/24/08 GOAL Maintain the semi -rural character of the community while providing for residential uses, open space, and the minimum public and private facilities and services needed to serve residents on a continuing basis. Policy 1.1 Uses of land shall be consistent with the semi -rural atmosphere of the community, minimize disturbance to natural terrain, minimize removal of the natural vegetation, and create the maximum compatibility of development with the natural environment through site design, architecture and landscaping. Policy 1.2 In addition to single-family residences, which may include a single secondary unit, uses within the planning area shall include: a. Those uses normally accessory to dwellings in a semi -rural area: vineyards and orchards, the keeping of horses and other domestic animals, and other agricultural pursuits that are compatible with residential uses; b. Those open space preserves, parks and recreational uses necessary to conveniently serve the residents; c. Those public and private services and facilities including schools, churches, fire stations, and community centers, needed locally to serve Town residents. Policy 1.3 Merge non-residential structures shall be compatible with the residential character of the community. Program LI Establish and maintain zoning that allows and supports the development of single-family residences and accessory structures, as well as appropriate non-residential uses. Program 1.2 Continue to implement the Town's Zoning Ordinance, Site Development Ordinance, Subdivision Ordinance, and related policies and procedures. Review and update these regulations as needed to ensure that development occurs in a manner compatible with the Town's semi -rural character and its natural environment. Land Use Element Los Altos Hills General Plan Page 4 Public Review Draft 3/24/08 LAND USE DESIGNATIONS Land Use Diaeram 113. The Town's Land Use Diagram on the following page illustrates the community's vision for the development, redevelopment, and preservation of public and private properties in the Los Altos Hills. The map designates the distribution and location of land to be used for housing, open space, recreation, public facilities, and other uses. Each of the land use categories designated on the Land Use Diagram is described below. The various land use categories have been applied to geographic land areas within the community to indicate which land uses the Town believes will be the most appropriate at that location. Residential (R) 114. The predominant land use shown on the Land Use Diagram is residential. One single- family dwelling is allowed per parcel. Accessory uses including one secondary dwelling unit may be permitted. Agricultural activities and conditional uses such as churches and schools also may be allowed. Open Space Preserve (OSP) 115. This designation is applied to undeveloped, natural areas that provide wildlife habitat, scenic views, and opportunities for nature study and low -impact outdoor recreation such as hiking and horseback riding. The primary purpose of this designation is the preservation and enhancement of the natural state of the land and its plants and animals. Allowable development includes paths and trails, informational signs, restrooms, open fencing, parking for the use of open space and Public Recreation Areas, and other incidental uses that are consistent with the protection of open space and the enjoyment of low -impact outdoor recreation. Open Space Conservation Area (OSCA) 116. This is an overlay designation that is superimposed upon the residential land use areas on the Land Use Diagram. The overlay is generally applied to areas of steep slopes, canyons and ravines associated with major creeks or their tributaries, as well as creek corridors and other areas of heavy vegetation that should be protected. Within these areas, special measures should be taken to conserve the natural quality of the area and to avoid environmental degradation. Residences should be placed on the most buildable portions of lands designated OSCA and carefully sited so as to preserve existing trees, vegetation and wildlife habitat. Public Recreation Area (RA -PB) 117. This designation identifies publicly owned open space lands used primarily for recreation. Development related to recreation is allowed. Examples include Westwind Community Barn, the Purissima Playing Fields (Little League Fields), and the Riding Arena. Private Recreation Area (RA -PR) 118. This designation identifies privately owned lands used primarily for recreation. Development related to recreation is allowed. An example is Fremont Hills Country Club. Institutional (D 119. This designation identifies academic, governmental and community service uses and lands that are either publicly owned or operated by non-profit organizations. Examples are schools, churches and other religious facilities, fire stations and Town government. Land Use Element Los Altos Hills General Plan Page 5 Public Review Draft 3/24/08 Land Use Element Los Altos Hills General Plan Page 6 Public Review Draft 3/24/08 DEVELOPMENT STANDARDS State Requirements 120. State planning and zoning law requires the Land Use Element to include a statement of the standards of population density and building intensity recommended for the planning area. As used in this element, the term density refers to population and development capacity of residential land. Density is described in terms of dwelling units per net acre of land and is related to the average slope of the parcel or lot. The term intensity refers to the extent of development on a parcel of land or lot (i.e., maximum development area). The Town's development standards for hillside protection, slope density, and other related concepts are described below. Hillside Protection 121. The rolling hills of Los Altos Hills are a highly valued natural feature of the community that should be protected. The hillsides provide important wildlife habitat, recreational opportunities, and scenic resources. Hillside areas are also subject to potential seismic hazards, landslides, fires, and other environmental hazards that can create risks to public safety, expose homeowners to potentially significant damage, and require extraordinary expenditures for public services. It is important to provide safe residential development while preserving the natural features, environmental integrity, and scenic character of the hills. 122. Low-density residential development can be compatible with hillside protection, especially where slopes are not excessively steep. As discussed in the USGS report in Appendix A, environmental concerns increase progressively as the slope of the terrain increases. To the maximum extent feasible, steep slopes, canyons and ravines, as well as natural swales and drainage channels, and geological hazard areas within areas designated for residential development should be left undisturbed and preserved in their natural condition. Slone Density Standards for Subdivisions 123. Within those areas designated for low density residential use, net lot area should be not less than one acre (43,560 square feet) per primary dwelling unit. In addition, the minimum net lot area for subdivisions should increase with an increase in average slope, based on the following slope -density standards: Average slope of land to be subdivided Minimum net lot size 0-10%slope One acre 10 — 50% slope An increase from one to seven acres, based on the average slope of the land. Over 50% slope These areas generally should not be developed for residential purposes. Land Use Element Los Altos Hills General Plan Page 7 Public Review Draft 3/24/08 Lot Unit Factor 124. The lot unit factor (LUT) for any given parcel is based on lot size and average slope as determined by a formula established in the Town's Zoning Ordinance. Newly created lots must have a LUF of one or more. Some lots with a LUF of less than one were created early in the Town's history, prior to incorporation. These lots are considered non- conforming and their development is restricted today. Lots with a LUF of less than one may not be created today. Lots with a LUF of less than .50 require a conditional development permit. Maximum Floor Area and Maximum Development Area 125. Floor area is the total square footage of a structure as specified in the Town's Zoning Ordinance. Development area is the total floor area of a residence, plus the total area of a parcel covered by other structures and hardscape not included in floor area. The maximum floor area (MFA) and maximum development area (MDA) for a parcel is based on the average slope and the Lot Unit Factor (LUF) as determined by formulas established in the Zoning Ordinance. 126. Building Setbacks Setbacks regulate the placement of buildings with respect to their property lines in order to provide a minimum amount of open space between buildings on adjacent parcels and between buildings and street rights-of-way. Setbacks for single-family residences are generally 40 feet from the front property line and 30 feet from the sides and rear property lines. Increased setbacks are required for estate homes over 10,000 square feet in size. Heieht Limits 127. The vertical height of buildings is limited to 27 feet in order to maintain a consistent, low profile that is compatible with the Town's semi-mral character. Building height may be increased to a maximum of 32 feet if setbacks are increased as specified in the Town's Zoning Ordinance. Green Building 128. In response to growing concerns about rising energy costs and dwindling natural resources, an increasing number of communities are embracing the concept of "green building." This whole -systems approach to homebuilding seeks to minimize the use of energy, water and other natural resources and maximize the use of recycled and renewable construction materials. The Town should develop programs and development standards regarding green building practices such as the use of recycled and renewable construction materials, energy-efficient heating and cooling systems, water conservation and reuse, and energy-efficient appliances. Land Use Element Los Altos Hills General Plan Page 8 Public Review Draft 3/24/08 GOAL Ensure that all development occurs in a manner that minimizes disturbance of natural terrain, vegetation and wildlife, and maximizes the preservation of natural resources and open space. Policy 2.1 Within incorporated Los Altos Hills and its Sphere of Influence dwelling types shall be limited to single-family detached residences, which may include a single secondary unit. Policy 2.2 Residential densities shall be guided by considerations of topography, vegetative cover and significant physical limitations inherent in the natural environment. Policy 2.3 The minimum parcel size shall be at least one acre and shall increase as the steepness of the land increases. Policy 2.4 In subdividing land, the number of dwelling units permitted shall decrease as the steepness of the land increases. Policy 2.5 Steep slopes, canyons and ravines generally in excess of 30% slope, as well as natural swales and drainage channels, and geologic hazard areas within areas designated for residential development shall be left undisturbed and preserved in their natural condition to the maximum extent feasible. Policy 2.6 Limits on the development of individual residential lots shall be determined based on evaluation of such factors as natural vegetation, topographic characteristics, soils and geology. Policy 2.7 The natural character of ridgelines shall be preserved to the maximum extent feasible. Policy 2.8 Promote the use of green building methods and practices in the planning, design, construction, renovation, operations, and demolition of buildings. Program 2.1 Continue to require the dedication of open space easements where appropriate as a condition of approval for new development. Each parcel shall be evaluated on a case-by-case basis during the site development review process to determine whether an open space easement should be required, based on the extent of steep slopes generally in excess of 30% slope and the presence of heritage oak trees and/or creek corridors. Other considerations shall include the size of the proposed open space easement, its contiguity with existing open space easements, and whether the property is located within an Open Space Conservation Area. Program 2.2 Limit grading on hillsides to the minimum extent necessary to accommodate structures. Structures should be located so that they are consistent with slope contours and compatible with the terrain. Land Use Element Los Altos Hills General Plan Page 9 Public Review Draft 3/24/08 Program 2.3 Encourage the preservation of existing trees, rock outcroppings, ridgelines and other significant natural features. Program 2.4 Encourage the preservation of hillside vegetation and, if vegetation must be removed, require appropriate revegetation and planting in hillside areas. Program 2.5 Protect the public safety and minimize the risk of damage from natural hazards by requiring site-specific geologic investigations of proposed building sites. Program 2.6 Continue to require soil erosion control measures on construction sites and require revegetation thereof. Program 2.7 Make green building publications and other sources of information available to applicants, architects, builders and other individuals involved in the construction of new homes and major remodel projects. Program 2.8 Consider developing a green building ordinance for site development and building applications. Program 2.9 Develop and implement a program for the reduction and recycling of construction and demolition waste. Open Space Easements Open space easements (OSE's) may be required as a condition of approval for site development. When an OSE is required, the property owner signs an agreement with the Town to keep the easement area undeveloped and in its natural condition. Once an OSE has been granted, the property remains under private ownership; the OSE does not give public access to the property. See the Open Space and Recreation Element far additional information on open space easements. Land Use Element Los Altos Hills General Plan Page 10 Public Review Draft 3/24/08 COMMUNITY SERVICES AND FACILITIES Public Schools 129. The Town is served by four public school districts: • Los Altos School District (K-8) • Palo Alto Unified School District (K-12) • Mountain View—Los Altos Union High School District (9-12) • Foothill Community College District Historically, the majority of Town residents attending public elementary school were enrolled at one of three public schools located within the planning area, all of which were located west of Foothill Expressway. After elementary school, Town residents then matriculated to middle schools that were located in either Palo Alto or Los Altos. Students then attended Gunn High School in Palo Alto or Los Altos High School or Mountain View High School in Los Altos, based on attendance areas. 130. Over the past 25 years, in spite of significant opposition from Town government and residents, the school districts have closed all three elementary schools so that children in the Town presently must commute to elementary schools in either Palo Alto or Los Altos. All commutes, by necessity, require the crossing of Foothill Expressway, which is a heavily traveled, four -lane roadway. Due to safety concems and the long distances involved, few elementary school children can walk to school. Many parents are unhappy with this situation and would like to have neighborhood schools reopened so their children can walk to school. Neighborhood schools are the basis for a successful, vibrant community where neighbors interact, establish common bonds, and provide a sense of community for all. 131. There are three existing public school sites within the Town's planning area. These sites are owned by either Palo Alto Unified School District (PAUSE) or Los Altos School District (LASD): • 26800 Fremont Road, formerly Fremont Hills Elementary School (PAUSD property). The District closed the public school on this site in 1995 and signed a long-term lease with Pinewood School, a private, non -denominational school. The Town has some limited use of the athletic fields in the summer. • 25890 Fremont Road, Bullis Purissima Elementary School (LASD property). The District closed the public elementary school on this site in 2005 despite substantial opposition from the Town govemment and residents. The District presently is planning to reopen the renovated elementary school in 2008. • 11311 Mora Drive, Los Altos (LASD property). This site is located in unincorporated area within the Town's sphere of influence. The District has closed the public elementary school and leased it to the Land Use Element Los Altos Hills General Plan Page 11 Public Review Draft 3/24/08 Waldorf School, a private school. The Town has no rights to use any of this property. Town surveys indicate that residents view recreational fields and playgrounds at public and private schools as an important community resource. The Town should work with school districts to permit public use of these facilities. 132. The Town believes that it is extremely important for its residents to be able to send their children to local elementary schools, with the majority of children having the ability to walk or bicycle to school. This can be achieved by reopening public elementary schools on the two sites noted above that are currently being leased to private institutions. Providing public schools for kindergarten through grade 6 within the Town boundaries that primarily serve Town residents is an integral part of imbuing the community spirit of our Town into our children. Not only do neighborhood schools at this level promote the establishment of lifelong friendships among the children, but they also encourage positive intercourse and friendships among the parents. This is the absolute basis for all successful and vibrant communities where neighbors interact, establish common bonds and provide a sense of community for all. 133. The Town believes its residents are well served by the middle schools and high schools operated by Los Altos School District, Mountain View—Los Altos Union High School District, and Palo Alto Unified School District. These schools provide excellent educational opportunities plus the extracurricular activities that the economies of scale of these large districts can provide. Foothill Community Colleee 134. The Town is served by an excellent community college in its midst, Foothill Community College. Like other public school districts, Foothill College is not subject to the Town's zoning and site development ordinances. The Town continues to work with the Foothill College administration to maximize the school's benefits to Town residents and minimize any traffic impacts and disruptions experienced by residents living near the campus. Private Schools 135. Private schools in the Los Altos Hills planning area include St. Nicholas School (K-8), Pinewood High School and the Waldorf School. The latter two are located on public school sites as discussed above. Land Use Element Los Alms Hills General Plan Page 12 Public Review Draft 3/14/08 Religious Facilities 136. Several churches or religious facilities are located in the Los Altos Hills planning area, including four that are located within city limits: • Poor Clare Monastery (Roman Catholic) • Congregation Beth Am (Reform Jewish Synagogue) • Chapel in the Hills (Episcopal) • Daughters of Charity (home for retired Roman Catholic clergy) All of these religious facilities hold conditional use permits issued by the Town. Town Government 137. The first Town Hall was built in the 1950's on land donated by the Town's first Mayor, Arthur E. Fowle, at the northeast corner ofhis 30 -acre ranch at Fremont and Concepcion Roads. The original facility served until 2004, when it was torn down because it no longer met building codes, seismic requirements and accessibility standards. It was replaced by a new energy- efficient facility that more than doubled the size of the original building. Dedicated on June 16, 2005, the new facility was designed to blend with the residential character of the community. The new facility not only embodies the rural aesthetic of the community, but also demonstrates the Town's commitment to energy and water conservation. 138. Two other buildings in the Town Hall complex provide a base for Town staff and services: • Heritage House, which is a historic house preserved by members of the community. The building is used as the Emergency Operations Center and local office of the County Sheriffs Department. • The Parks and Recreation Center, located in the building formerly used by the Water Parks and Recreation Center District. Is next to Town Hall Both buildings have recently been remodeled in order to better meet the needs of the community. The Town's corporation yard is located on Purissima Road adjacent to the Purissima Playing Fields (Little League Fields). It serves as the center for the Town's maintenance crew and mechanical equipment. a historic building. Energy�ficient Council Chambers incorporate natural lighting. Land Use Element Los Altos Hills General Plan Page 13 Public Review Draft 3/24/08 Public Recreation Facilities 138. Town -owned parks and recreation facilities include Byme Preserve and six other open space preserves; Westwind Community Bam; Purissima Playing Fields (Little League Fields); the Riding Arena; and Edith Park. In addition, the community's extensive system of roadside and off-road paths provides recreational opportunities. Recreation programs sponsored by the Town include youth camps, fitness programs and the annual Pathways Run. Private Recreation Facilities 139. Privately owned recreation facilities in the planning area include Fremont Hills Country Club and several other country clubs in neighboring cities, as well as Hidden Villa, the Stanford University lands, and private boarding stables. Fire Protection 140. The Los Altos Hills County Fire Protection District is a separate public agency, distinct from the Town, that contracts with the Santa Clara County Fire Department for the provision of fire protection, suppression and safety services. The District owns and operates the EI Monte Fire Station near Foothill Community College. Police Protection 141, The Town contracts with the Santa Clara County Sheriffs Department for police protection services. The Sheriffs Department typically provides one or two patrol cars at all times, which is adequate because Los Altos Hills is a low -crime community. In the event of emergencies, however, the Town has access to the full resources of the County Sheriff. The Town also has a public safety officer on staff and provides a substation at the Heritage House next to Town Hall for the use of the County Sheriff. Public antl private recreation facilities a2 described in the Open Space &Recreation Element, which also includes related goals, policies antl programs. Fire and police protection services are described in the Safety Elemen( which also includes relatetl goals, policies aM programs. Emergency Services 142. Ambulance and paramedic services are provided by Santa Clara County on contract with the Los Altos Hills County Fire District. Emergency response In the event of a major disaster such as earthquake or fire, services are described in the Safety Element, emergency response services are coordinated by the Town as which also inGutles established in the Emergency Operations Plan. The Town's related goals, policies Emergency Operations Center (EOC) is located in the Heritage and programs. House adjacent to Town Hall. Land Use Element Los Altos Hills General Plan Page 14 Public Review Draft 3/24/08 GOAL Encourage the development of community services and facilities that are easily accessible, properly related to adjacent land uses, and in harmony with the semi -rural, residential character of the community. Policy 3.1 School districts shall be encouraged to restore neighborhood public elementary schools in Los Altos Hills. Policy 3.2 The Town will encourage institutional uses that are necessary to serve local residents, such as public schools, churches, governmental buildings, public recreational facilities and fire stations. Policy 3.3 Major community facilities should be located where they can be served directly by collector, or where possible, arterial roads so that they are reasonably convenient to residents. The primary consideration should be compatibility with adjacent land uses and with preserving the semi -rural, residential character of the Town. However, given the lack of commercial buildings and minimal number of institutions in the Town, some institutional structures by necessity will be adjacent to residential properties. Policy 3.4 Every effort should be made to ensure that recreational areas and playing fields at both public and private schools are available for use by Town residents during non -school hours. Policy 3.5 School service areas should be defined so as to maximize the number of children who can walk to schools within the Town borders, with particular emphasis on the use of the Town pathway system, using both on -road and off-road paths. Policy 3.6 Public buildings should be of a size and scale conducive to maintaining the semi -rural atmosphere of Los Altos Hills. The architectural design of non-residential buildings should incorporate those principles that guide our residential homes such as modest height and bulk appearance. Program 3.1 Work with Palo Alto Unified School District and Los Altos School District to reopen public elementary schools in Los Altos Hills. Program 3.2 Cooperate with school districts in providing demographic data and other information supporting the need for new schools. Program 3.3 Continue to assist school districts by requiring the payment of school impact fees as per Government Code Section 65995 prior to issuance of building permits. Program 3.4 Explore innovative ways for the community to use school facilities and groundsjointly with the school districts. Program 3.5 Work with school districts in the design and development of school facilities to provide for community needs in the areas of parks and recreation, community meetings, and similar activities. Land Use Element Los Altos Hills General Plan Page 15 Public Review Draft 3/24/08 Program 3.6 Work with school districts to minimize potential impacts on neighboring residential areas. Program 3.7 Continue to require conditional use Permits for the location and operation of private schools, churches and other institutional uses. Monitor and mitigate potential impacts on neighboring residential areas by limiting the hours of operation, the location of parking, and other factors as appropriate.

Land Use Element Los Altos Hills General Plan Page 16 Public Review Draft 3/24/08 UTILITIES Anticipated Needs 143. The Town is expected to experience very modest growth mostly through infill development and redevelopment of underdeveloped parcels. As a result, the need for a full range of public facilities and urban services is expected to grow very modestly in the future. To preserve the natural environment and semi -rural atmosphere desired by the residents of Los Altos Hills, it is important that the installation and/or extension of utilities be conditioned by concerns for preventing damage to the natural beauty and environmental integrity of the area. Standards for the extension of utilities, sewers in particular, must be based on health and safety considerations as well as environmental protection. Water Supply 144. The Town's drinking water is provided by two water suppliers: Purissima Hills Water District and the California Water Service Company (Cal Water). As discussed in the Conservation Element, the amount of water available is constrained. Purissima Hills presently obtains all of its water from San Francisco's Hetch Hetchy system and currently is exceeding its supply assurance by 25-35 percent. Capacity limitations in the Hetch Hetchy system may be reached in six to eight years, or sooner yyater resources are in times of drought. Cal Water obtains the water supplied to also discussed in the Los Altos Hills from the Santa Clam Valley Water District via Conservation Element, pipelines from the Santa Clara Valley Water District's which inGutles related Rincohada treatment plant and from company-owned wells. goals, policies& During the dry season, the plant and pipelines are at capacity. Programs. Sanitary Sewer 145. There are more than 3,100 parcels within the Town, of which less than half are currently connected to the municipal sanitary sewer system. The existing municipal system includes approximately 52 miles of 6- to 12 -inch diameter gravity pipelines, several reaches of forcemains, 1,305 manholes, and 2 lift stations. The Town straddles two drainage basins, including the Palo Alto Basin to the north and the Los Altos Basin to the south. Sewage collected by the Town's existing system is conveyed to sewer trunk lines owned by the cities of Los Altos and Palo Alto, with the portion of the Town in the Palo Alto Basin draining into the City of Palo Alto municipal sewer system, and the Los Altos Basin draining into the City of Los Altos municipal sewer system. The use of conveyance and treatment systems owned by these cities is governed by separate service agreements with the Town. The wastewater from all three communities eventually drains into the Palo Alto wastewater treatment plant for treatment and disposal. 146. While there has always been sufficient capacity in the Palo Alto system to accommodate all residences on the north side, the Town has been constrained by capacity limitations in the Los Altos system. However, in 2007, the Town and the City of Los Altos signed a new contract that provides additional capacity that will now allow all residences within corporate limits ofthe Town and its sphere of influence to access sewers. 147. The Town prefers that as many residences as practicable connect to the sewer system. While a properly constructed and maintained septic system typically does not present an environmental hazard, the failure of a septic system can induce contaminants into the underground water table. Also, smaller lots may not be able to replace a failed system Land Use Element Los Altos Hills General Plan Page 17 Public Review Draft 3/24/08 due to issues regarding the construction of a new leach field. The Santa Clara County Health Department requires all new residences to connect to the sewer system if there is an existing sewer main with 200 feet of the new residence. 148. All new residences resulting from new subdivisions should be served by sanitary sewer trunk lines. All new residences resulting from the teardown of an existing residence or a newly constructed home on an existing lot should be required to connect to sanitary sewer trunk lines, provided there is an existing trunk line within 200 feet of the new residence. Wherever the possibility of biological harm from septic tank use exists, requirements for conversion to sanitary sewers should be established. Standards should reflect Bay Area Water Quality Control Board and Santa Clara County Health Department requirements. 149. The Town has appointed a committee to review the existing issues in regard to bringing sewer mains to as many neighborhoods as possible. This committee has conducted a survey among residents on septic tanks to determine the major issues that prevent these residents from connecting to the system. Through various methods such as sewer reimbursement districts, sewer assessment districts and the extension of sewer mains up main arteries to make sewer connection more accessible, the Town hopes to significantly increase the number of residences connected to the sewer system. Storm Drainage System 150. The Town's storm drainage system consists of a combination of roadside drainage ways, cross culverts, and underground pipes. Stormwater in Los Altos Hills initially flows over land, following the natural contours of the terrain and then moving to roadside flow routes. Some of these are paved with asphalt concrete, but most roadside flow routes are din ditches, which help preserve the natural, semi -rural feel of the community. Stormwater in the roadside flow routes travels downhill to culverts, pipes or creeks that eventually carry the storm runoff to the San Francisco Bay. 151. Silt and debris in the storm drain system sometimes cause water to back up and flood the surrounding areas. The Town provides maintenance of the stormwater facilities in the public right-of-way, including culverts crossing under public roads and public roadside flow routes. This also includes areas Areas subject to fiootling are addressed where the Town has permanent storm drain easements for in the Safety Element, public drainage structures on private property. Although which inductee related regular maintenance helps prevent flooding problems, in some goals, polbies & cases the repair of deteriorated facilities and construction of Programs. new facilities is needed to improve the storm drainage system. 152. The Storm Drainage Master Plan prepared in November 2004 identifies the location of drainage problem areas in the Town and proposes solutions ranging from the installation of new pipes and catch basins to the regrading of ditches and provision of riprap protection. The Master Plan ranks the proposed projects in order of priority and estimates the costs involved. Each year the Town adopts a Capital Improvement Program that includes some of these projects and budgets for their completion.

The conditions of the permit require the Town to reduce pollution in urban runoff to the maximum extent possible. Recent changes strengthen the regulations for projects that replace or create new impervious surface. The permit must be reissued every five years. Policies and programs related to stormwater quality are contained in the Conservation Element. Constmcmd in 2007, the Purissima Hills Water District building was designed to blend in with the residential character of the community. Its drought -tolerant landscaping serves as a model for water conservation.

The residents of Los Altos Hills depend on cell phones and other forms of wireless communication services for convenience, business activities and security. As one of the premier residential areas of the Silicon Valley, the Town should have a high level of wireless service available to its residents in order to meet increasing demands for new and better services. However, the Town's topography, with its steep slopes and canyons, have made cell phone reception problematic. To meet the demands for new and better services, providers need an adequate number of wireless communication facilities in the planning area. 155. The Town currently has I I cell sites, each shared by multiple service providers who have co -located antennas and equipment. Because the Town is entirely residential, with no commercial or industrial areas, wireless communication facilities are most appropriately located on Town property or other public or institutional sites such as schools and churches. The location of new facilities on or near existing buildings, the co - location of antennas owned by two or more companies, and landscape screening should be utilized to minimize any adverse visual impacts. To ensure that new facilities are appropriately located, the Town has developed policies and siting criteria for wireless communication antennas and equipment Wireless communication facility at shelters. These policies and siting criteria Wesrwind Bemis designed to blendin with the scenery should be reviewed and updated as needed. GOAL Provide adequate, reliable utilities and urban services that will protect the health and safety of all residents, while minimizing environmental and aesthetic impacts on the community.

Program 4.4 Continue to implement the Town's policies and siting criteria for wireless communications facilities, and review and update them as needed. Land Use Element Los Altos Hills General Plan Page 21 Public Review Draft 3/24/08 GROWTH BOUNDARIES Sphere of Influence (SOI) Boundary 156. As required by state law, the Local Agency Formation Commission (LAFCO) has adopted a Sphere of Influence (SOI) for each city and special district in Santa Clara County. The SON are intended to ensure that urban development takes place in an orderly manner, to preserve agricultural and open space lands, and to ensure that the land use and development policies of a city are recognized in areas that will eventually be part of a city. 157. The SOI indicates areas that may be annexed to the Town and for which urban services, if available, could be provided. The Town's existing SOI, which was adopted in February 1985, is coterminous with the town limits to the north, west, and most of the east. The boundaries of some of the Town's unincorporated islands, unincorporated hillside lands, lands within the Midpeninsula Regional Open Space District's Rancho San Antonio Open Space Preserve, and lands within the County of Santa Clam's Rancho San Antonio Park help form sections of the southern and southeastern portion of the Town's SOI boundary. Permanently preserved open space areas such as MROSD's Rancho San Antonio Preserve do not require urban services, but are appropriately included in the SOI due to their location. Unincorporated Pockets in Urban Serviced Area (USA) 158. The urbanized unincorporated areas within the Urban Service Areas (USA) of Los Altos Hills are referred to as urban pockets or islands. The pockets are a result of development that occurred in the County in the 1950s and 1960s. Santa Clara County and LAFCO have adopted policies that state that urban islands and pockets should be annexed. There are seven unincorporated urban pockets within the Los Altos Hills urban service area (USA). Figure 1-2 shows current Town boundaries and urban pockets subject to future annexation within the Town's planning area. Prezonine 159. The purpose of prezoning an area is to establish the zoning district that will apply in the event of subsequent annexation to the Town. The proposed zones must be consistent with the General Plan, and the prezoning has to be approved by the City Council at a public hearing. There are two advantages to prezoning. First, the Town will have zoning in effect immediately upon annexation. Local residents will thereby have prior knowledge of the land use regulations that would affect them should annexation occur. Secondly, prezoning acts to serve notice to LAFCO of the city's intentions regarding its adjacent areas. Prezoning is the procedural first step necessary to ultimately annex a particular territory. However, the act of prezoning does not compel the Town to initiate annexation proceedings. Land Use Element Los Altos Hills General Plan Page 22 �. v _f !!i llrRiY!� � Public Review Draft 3/24/08 160, In August 2002, the Town prezoned approximately 245 parcels in unincorporated county lands known as San Antonio Hills. The prezoned area is generally between Ravensbury Avenue and Interstate 280, including portions of West Loyola Drive, Mora Drive, and Berkshire Drive. In March 2006, the Town prezoned an additional 82 parcels between Magdalena and Eastbrook Avenues including properties on Spalding Avenue, Par Avenue, Winding Way, Putter Avenue and Putter Way. Annexation 161. Subsequent to the prezoning of San Antonio Hills in 2002, the Town annexed 118 parcels totaling 142 acres within the unincorporated urban pocket. (Ravensbury Annexation, March 2002; West Loyola Annexation, September 2007) The properties in the annexed areas are mostly developed with single- family homes on parcels of one acre or more. There remain approximately 280 acres of unincorporated land within the Town's Urban Service Area that may be subject to annexation in the future. The Town should conduct a comprehensive evaluation of all future annexations to ensure that they are compatible with the land use patterns and zoning designations of the Town and that such annexations do not negatively impact the Town's finances, facilities and services. Areas of Direct Concern 162. Areas of Direct Concern are within the planning area but beyond the Town's corporate limits and the Sphere of Influence. These areas include several pockets of existing residential and commercial/industrial development as described below: Residential Areas Portions of several residential areas in Los Altos and Santa Clara County are included within the planning area. These areas, although in other jurisdictions, are of direct and immediate concern to the planning area because of common problems relating to drainage, circulation, public facilities, and visual amenities. Existing development within the portion of Los Altos that is within the planning area is low-to-medium density residential. Development of existing vacant land immediately adjacent to Los Altos Hills should be no more intense than one-half acre per dwelling unit in order to provide a gradual transition between residential densities as previously agreed to by the City and the Town. Commercial/Industrial Areas The planning area includes commercial areas within the City of Los Altos and light industrial development in the Stanford Industrial Park. These areas, however, do not occur within the Town limits or its SOI. Land Use Element Los Altos Hills General Plan Page 24 Public Review Draft 3/24/08 GOALS Ensure that the Town's growth will proceed in an orderly, planned manner in order to provide efficient and economical urban services. Policy 5.1 Issues within the Sphere of Influence shall be monitored for their effects on the Town. Policy 5.2 Any proposed annexations shall be consistent with the Town's General Plan land use designations and adopted annexation procedures. Policy 5.3 Maintain a cooperative working relationship with Santa Clara County regarding land use issues. Program 5.1 Request that Santa Clara County and other applicable agencies refer all proposed projects and programs within the Sphere of Influence to the Town of Los Altos Hills for review and comment, and act favorably on the Town's recommendations. Program 5.2 Review annexation proposals to assure that they are consistent with Sphere of Influence boundaries, General Plan land use designations and established annexation procedures and criteria. Program 5.3 In evaluating proposed annexations, require the preparation of fiscal impact analysis to determine the costs and benefits to be received by the Town as a result of the proposed annexation.

Brooks, Arthur H. Lachenbruch, and Carl M. Wentworth Open -File Report 02-351 Version 1.0 2002 Excerpted from a Land Use Planning USGS Report - Department of the Interior 1001 By Suzann K. Brooks, Arthur H. Lachenbruch, and Carl M. Wentworth Plannine with Slone Problems of regulating the creation of flat space and impermeable surface and their community impacts are generally greater for steeper slopes (Nilsen and others, 1979, p. 80). Whether such problems might require regulation in any particular community depends upon the community's physical setting and planning goals. For the example of Los Altos Hills, Figure 3 shows that about one third of the community has slopes less than 10%, a category in which experience has shown that grading, erosion, and other development alterations to the natural terrain can generally be handled without difficulty (Mader and others, 1988). According to Figure 3, almost half of the community has slopes from 10% to 30%, a slope category usually targeted for residential development but with progressively increasing concerns and regulatory restrictions toward the upper limit. In the one fifth of the town with slopes greater than 30% (Figure 3), residential development without extensive modification of the surroundings becomes increasingly difficult, and much of the land may be classified for limited uses with conservation easements, or with an open space designation. Because slope is a fundamental physical parameter affecting land use in hillside communities, the community general plan and many controlling ordinances (e.g. for grading, lot size, house size, development intensity, foundation design, impermeable surface area, erosion control, and conservation easements) are often formulated in terms of the slope of the land. The slope map (Figure 2) provides a useful means of viewing the distribution of these potential problem areas, and of visualizing the community -wide implications of various regulations proposed to deal with them. Flat Soace and Gradin Typically, to create a square one -acre flat pad with balanced amounts of cut and fill on a hillside where the natural slope is 20%, a total of two acres of natural terrain must be altered by grading (Figure 4) - the second acre is occupied by the steep compensating cut and fill banks (typically 67% and 50% respectively). Similarly, where the natural slope is 30%, about three acres must be graded to produce one flat acre (see dots, Figure 4A) - the remaining 2 acres are occupied by cut and fill banks that are roughly twice as steep as the original surface. ... The graded cut -and -fill slopes are not only steeper than the natural surface, they are stripped of existing trees and other vegetation; both factors can contri- bute to the instability and visibility of the graded slope.

The Town's pathways system serves four basic and important functions: • Circulation throughout the community • Safe access and emergency routes • Outdoor recreation/fitness • Preservation of the open character of the Town The pathways system is designed to complement the Town's roadway system and to enhance non - motorized circulation by providing connections between neighborhoods and access to local or nearby destinations. The Pathways Element is an optional element of the General Plan. However, it is closely related to several mandatory elements including the Circulation & Scenic Roadways Element, the Safety Element, and the Open Space & Recreation Element. Pathways offer an alternative mode of travel through Town. Roadside Paths 102. The Town's pathways system is composed of roadside paths and off-road paths. Roadside paths are located within or adjacent to the road right-of-way. The road right-of- way is generally planned to have the needed width to accommodate both the paved road as well as a separated path. Roadside paths provide safe routes for pedestrians and equestrians in the Town, much as sidewalks function in more urban communities. Roadside paths separate the car and the pedestrian or other non -vehicular user, and allow each a safer movement. The hills of the Town result in streets that often have steep sections or blind curves, which make pedestrian separation more important than with a grid street system. Off-road Paths 103. Off-road paths provide links between adjacent neighborhoods and schools for pedestrians, bicyclists and equestrians. Off-road paths, which connect to roadside paths or open space lands, are generally located on dedicated easements on private property (usually along property lines), through public lands, or through privately owned conservation/open space easements. Off-road paths make it possible to travel by foot or horseback to nearby neighborhoods without using Town roads. Recreational Functions 104. In addition to providing access to nearby destinations, paths provide a place to exercise, walk dogs, or ride horses. The primary users and beneficiaries of most of these paths are local residents. Path -related recreational activities such as walking, jogging, hiking and Pathways Element Los Altos Hills General Plan Page 1 Public Review Draft 3/24/08 horseback riding are among the most popular and rapidly growing forms of outdoor recreation as the public is becoming increasingly more health and fitness conscious. 105. Pathways are frequently constructed of pervious materials to maintain the Town's open and rural setting, and to further enhance the recreational experience. Both the recreational and circulation functions of the paths will become even more important as their popularity and the demand for recreational opportunities increase. History of Pathways 106. Even before the Town was incorporated in 1956, the Local paths provide pathways system began to develop unofficially as a passage to wander over network of trails throughout the community. Over the and to explore the years, as new subdivisions developed and the population increased, the use of paths and their popularity increased. natural areas of the The pathways system was formalized when the Town Town and provide the incorporated, and paths expanded incrementally as inter -connecting strands development occurred and the population grew. Regulations were established to require each new of the web that help development that adds potential new pathway users to bind the community contribute to the pathways system through the dedication together. of easements and the construction of paths or payment of pathway fees. Pathway fees are used by the Town for From the 1981 Pathways Element improvement and maintenance of the pathways system. Implementing the Master Path Plan 107. The pathways system is and remains a work in progress. Implementation of the Master Path Plan through the acquisition of easements and the construction and maintenance of individual paths will take many years to accomplish because paths are generally constructed one segment at a time as new development occurs. In most cases, the acquisition of pathway easements occurs during subdivision or site development review, although in some cases easements have been acquired through voluntary contribution. Construction of pathways is usually performed by property owners as a condition of approval for site development or by the Town as a capital improvement project. The incremental nature of the process makes it critical that the Town has a clear and equitable policy regarding the acquisition of easements, payment of pathway fees, and construction and maintenance of pathways. (The Master Path Plan is included as Appendix A.) Key Terms The terms 'path* and "trail" are used interchangeably, although trail usually refers to a path (or pathway) in a more natural condition or setting. Pathways Element Los Altos Hills General Plan Page 2 Public Review (haft 3/24/08 Regional Connection 108. The pathways system of the Town is intended primarily for the use of Town residents but it should be connected to the path and trail systems of neighboringjurisdictions. • Palo Alto The Town and Palo Alto pathways along Arastradero Road provide links from the Town to Arastradero Preserve, to Esther Clark Park via Fremont Road, Old Trace Lane, and Aric Lane trails, and to Gunn High School via Palo Alto trails. It would be very desirable if Foothill Park (City of Palo Alto) trails were also accessible from Town paths along Page Mill Road, also allowing for connection to the Skyline Trail. • Los Altos Access from and to Shoup Park and Redwood Grove in Los Altos, along Adobe Creek to O'Keefe Lane and the Town's pathway system, and a link between Fremont Road and Redwood Grove would improve pedestrian access for both cities. Open Space Preserves The western boundary of the Town meets Rancho San Antonio Open Space Preserve, which is owned and operated by the Midpeninsula Regional Open Space District. This Preserve has an extensive trail system that attracts large numbers of visitors. The primary entrance to the Preserve, where extensive parking is available, is at Rancho San Antonio County Park at the end of Cristo Del Rey Drive in Cupertino. Connections to the Preserve from the Town are intended for local residents and have limited parking. Improved access to open space lands should also be pursued. De Anza Trail 109. The De Anza Trail, which Congress has designated as a national historic trail, passes through Town. It is expected that the historic trail will be designed and completed in the future, and the trail should be designated on the Master Path Plan at that time. Historic De Anza Trail The Juan Bautista de Anza National Historic Trail is a historic route from Nogales, Arizona to San Francisco, California. The trail commemorates the 1775-1776 Spanish Expedition, in which Captain de Anza led almost 300 people over 1,200 miles to settle Alta California. The trail was the first overland route to connect New Spain with San Francisco. Pathways Element Los Altos Hills General Plan Page 3 Public Review Draft 3/24/08 THE PATHWAYS SYSTEM GOAL Develop and maintain a safe, convenient pathways system that allows non -vehicular travel throughout Town, meets recreational needs of residents, and provides regional connections. Policy 1.1 All residents of the Town shall have immediate access adjacent to or across the street from their residence to a pathway or pathways, for safe and convenient pedestrian and other non -vehicular travel along Town roads and to schools and community facilities, and for recreational enjoyment of the natural amenities of the community. Policy 1.2 Pathways shall serve to provide access to and from neighborhoods in the event of an emergency. Policy 1.3 Pathways shall be separated from the roadway pavement wherever possible and meander wherever paswhere necessary to accommodate [opoeraphv trees and landscaping. Policy 1.4 All paths shall be located and designed to preserve the beauty and natural character of the area and to safeguard the user. Policy 1.5 Except for connections to regional trail and bikeway networks, Town paths shall be designed primarily for local circulation and recreational use. Policy 1.6 The Town shall maintain the pathways, using both pathway fees and General Fund monies. The annual Pathways Run is a popular event. Pathways Element Los Altos Hills General Plan Page 4 Public Review Draft 3/24/08 ROADSIDE PATHS Goal 2 Develop and maintain a system of roadside paths adjacent to public and private streets. Policy 2.1 Roadside paths shall be located within or immediately adjacent to the right-of- way of Town streets and on separate pathway easements adjacent to or over private streets. Roadside paths shall be separated from the roadway pavement by landscape buffering and shall meander, where possible. Policy 2.2 The Town Council shall adopt a list of those streets or segments of those streets that shall be planned for paths on both sides of the street. (The approved list is included in Appendix B.) Policy 2.3 A roadside path shall be maintained on only one side of the street unless the street is included on the list adopted pursuant to Policy 2.2. The path may be located on alternating sides of the street, however, depending on factors such as available easements, topography, or proximity to schools or other facilities. If only one side of the street is in Los Altos Hills there should be a path on the side within the Town's corporate limits.

Pathways Element Los Altos Hills General Plan Page 5 Public Review Draft 3/24/08 OFF-ROAD PATHS Goal 3 Develop and maintain a system of off-road paths that provide connections between neighborhoods and direct routes to schools and open space preserves. Policy 3.1 Off-road paths shall be located on private property on easements that have been dedicated to the Town, or over public lands. They shall provide connections between neighborhoods and provide direct routes to schools and open space. Cul- de-sacs should have off-road paths that connect the end of the street to adjoining neighborhoods whenever possible. Policy 3.2 There are shall be three classes of Off -Road Paths: Class 1- Off-road paths for which easements have been granted to the Town for a completed route, on which a path has been developed or pathway use has been established, and which is maintained by the Town and is open for public use. Class 2—Off-road paths for which easements have been granted to the Town for less than a completed route, or where the pathway easement exists but the path has not been constructed or maintained and is not open for public use. Such paths remain to be completed in the future. Class 3—A planned future off-road path, as shown in the Master Path Plan. These paths may need dedication of easements over a single large parcel of land, or may require easements over a number of smaller parcels. Policy 3.3 Off-road paths are shall be a permitted use in a onservation and open space easements, and should be reflected as such in the language of the easement agreement at the time of dedication.

Policy 3.5 The design of new subdivisions—especially those with cul-de-sac streets—shall incorporate pathway connections to nearby neighborhoods or community facilities, such as schools, and to open space areas. Policy 3.6 Dedication of off-road pathway easements shall not affect the computation of the net area, LUF (lot unit factor), MDA (maximum development area) or MFA (maximum floor area) for a lot. Policy 3.7 Off-road paths shall be maintained in as natural a state as possible, except that installed surfaces may be acceptable when paths serve as connectors to schools or neighborhoods, or where special use or topography make it necessary. Policy 3.8 Off-road paths shall be located along or as close to property lines as possible. Pathways Element Los Altos Hills General Plan Page 6 Public Review Draft 3/24/08 THE MASTER PATH PLAN Goal 4 Maintain and implement the Master Path Plan to ensure development of the Town's pathways system. Policy 4.1 The Master Path Plan shall consist of all of the following: Policy 4.2 a. A book of street maps of the Town showing streets with paths planned on both sides of the street, after adoption by the City Council (see Policy 2.2). b. A book of street maps of the Town showing the side of each street on which a roadside path is planned.

The pathway fee shall be established FA anexienxf r"•'" aky weFe required, by Town ordinance. Paths shall be constructed by propertv owners as site development occurs In some cases the Town may construct paths as funding permits. Policy 4.3 All new development which is expected to result in an increased demand for use of pathways shall comply with requirements for non -vehicular access, including dedication of easements and/or construction of paths, or payment of pathway fees, as follows: a. All subdivision development (except for lot line adjustments) shall be required to comply with pathway requirements, as the project would result in an increase in the number of homes (and residents) in the Town. b. All proposals for new main residences and/or secondary dwelling shall be required to comply with pathway requirements, as the project would result in an increase in the number of residents in the Town. c. A cumulative development of 900 square feet of habitable floor area or greater shall be required to comply with pathway requirements, as 900 square feet is considered a major addition requiring Planning Commission discretionary review; is generally the sin of a large master bedroom and bathroom suite or three smaller bedrooms, based on typical submittals to the Town; and is roughly equivalent to the average area of floor space per Town resident, resulting in an increase (presently or in the future) in the number of residents in the Town. d. Development of a ham or stables in excess of 900 square feet shall be required to comply with pathway requirements, as the project would generate additional stable capacity and place an increased burden on the equestrian use of pathways. e. Other types of development proposals, such as conditional use permits or variances, weeld-shall require a specific justification by the Town of the nexus for pathway requirements for that particular project. Policy 4.4 Where pathway installation is required for a project, construction of the path shall occur concurrent with development of the project, unless the Planning Commission or Council determine that the path would serve no useful purpose in the near future, due to the incompleteness of the pathway segment. Policy 4.5 A lot that contributed a pathway fee at the time of subdivision shall not be required to contribute again at the time of initial site development. Policy 4.6 Pathway fees shall be deposited in a designated fund and used only for pathway projects. Pathways Element Los Altos Hills General Plan Page 8 Public Review Draft 3/24/08 Policy 4.7 The incremental development of the pathways system sometimes results in gaps in both the roadside and off-road pathways. Public funds available to the Town, including the pathway fees, shall be used on projects that will complete the gaps in the system. Policy 4.8 Pathway standards shall be adopted by resolution of the City Council to address roadside and off-road pathway design. Policy 4.9 Site development authorities shall be sensitive to path location and design. This is especially the case for the off-road paths. The location shall be sensitive to the privacy of future residents whenever a parcel is subdivided or a lot is developed. All paths shall be located and designed to preserve the beauty and natural character of the area and to safeguard the user. Particular care shall be given to retaining trees and vegetative cover and to minimize grading and erosion. Policy 4.10 Typically, off-road paths shall be located along property lines, when topography permits. Fencing along paths may sometimes be appropriate to protect privacy, so long as it does not intrude into easements or right-of-way. Policy 4.11 Street trees along the roadside path system should be promoted to enhance the pathway experience, but shall be located to avoid conflict with path use. Policy 4.12 Property owners who damage paths on their property shall be required to repair them. Damage can occur by landscaping planted too close to the path, sprinklers near the path, slippery driveway surfaces across a path, or disking too close to the path. Policy 4.13 Class I off-road paths shall have sign posts at their entrance to help residents locate them and feel free to use them. Policy 4.14 Major off-road paths should be named as a way to encourage their use and to recognize historical entities associated with the Town or to honor Town residents who have contributed to the development of the system. Policy 4.15 The Town shall accept offers of dedication of pathway easements made at the time of development and record them so that the future pathway right-of-way is identified. Policy 4.16 The Town should shall seek donations of pathway easements needed to complete gaps in the system. The Town shall assume the legal and engineering casts involved with the preparation of easement donations unrelated to development and should inform residents of possible tax advantages from easement dedication. Policy 4.17 A Pathways Committee of residents interested in the pathways system shall be appointed by the Council. A major responsibility of the Committee shall be to suggest priorities for the Council and the City Manager regarding those paths most in need of maintenance or development. The Committee shall also be responsible for the maintenance and development of the Master Path Plan. Pathways Element Los Altos Hills General Plan Page 9 Public Review Draft 3/24/08 Policy 4.18 Property owners shall not block pathways or otherwise impede pathway use through the placement of fences, landscaping, irrigation, mailboxes, or any other means. Policy 4.19 Provision for pathway crossings or bridges shall be made at appropriate locations, such as across creeks, and all roadway vehicular bridges shall be designed to incorporate pathway crossings. Policy 4.20 Trails and paths shall be permitted uses in open space and conservation easements. These trails shall be constructed and maintained to minimize the environmental impact upon the area. Policy 4.21 When a pathway crosses a driveway or walkway, the pathway surface shall take precedence to provide safe footingfor or equestrians and pedestrians. Where a paved surface is required, the crossing must be acceptable as a pathway, e.g., roughened. Policy 4.22 The Town shall maintain a walking map available to residents that indicates all roadside and off-road paths that are passable. Program 4.1 Continue to implement the Master Path Plan by requiring the dedication of easements, construction of pathways and/or payment of pathway fees as a condition of approval for subdivisions and site development permits. Program 4.2 Continue to improve the Town's maintenance of constructed pathways. Program 4.3 Review the approved list of streets that should have paths on both sides and update the list as necessary. Program 4.4 Review the walking map on a regular basis and update the map as necessary. Program 4.5 Develop, adopt and implement an ordinance that codifies pathway requirements and regulations. Pathways Element Los Altos Hills General Plan Page 10 Public Review Draft 324/08 A Unique Community Asset The pathways system is a network of paths and trails designed to provide safe, convenient non- vehicular travel throughout the community. Used by school children, walkers, runners, equestrians and bicyclists, the pathways system meets recreation and circulation needs of residents. The system unites neighborhoods through a series of oonnecfing paths that crisscross the Town. Pathways also allow access to natural areas so that residents can better enjoy the community's scenic countrysides.

Pearson-Arastradero Preserve is a 609 -acre open space preserve located in the foothills on the west side of Highway 280. The preserve is owned and maintained by the City of Palo Alto and can be accessed by off- road pathways in Los Altos Hills. • Foothills Park is a 1,400 -acre recreation area located 2.7 miles west of Highway 280 at 3300 Page Mill Road. The park is adjacent to the Town of Los Altos Hills and within its planning area, but the park is open only to residents of Palo Alto. Planning and Zoning Open space preserves are designated Open Space Preserve (OSP) on the Land Use Diagram and zoned Open Space Reserve (OSR). Permitted uses in the OSR zoning district include agriculture, forestry, and low -impact outdoor recreation such as horseback riding, hiking and bird watching. No buildings or other development are allowed. Steep canyons and creek corridors that should be protected are designated as Open Space Conservation Areas on the Land Use Diagram. Development in these areas is generally limited to off-road pathways; no structures are allowed. In addition to canyons and creek corridors, visually important open space lands associated with major religious and educational institutional facilities or with Stanford Industrial Park are designated Open Space Conservation Areas. Other open space lands that are used primarily for recreation are designated Public Recreation Area or Private Recreation Area on the Land Use Diagram. These recreation areas are protected from other types of development and uses.

The proposed amendments do not include any changes in land use designations because the Town is nearly built out and significant population growth is not expected in the future. Phase 3 of the General Plan update includes amendments to existing goals, policies and programs to address current issues related to land use and the Town's pathways system. Most policies and programs in the updated elements are already existing; proposed changes and additions are intended to clarify and strengthen existing goals and policies. No major changes in policy direction are included in the General Plan update. The Town is committed to the preservation of the semi -rural, residential character of the community, the protection of natural open space, and the maintenance and development of the pathways system. Implementation of the updated goals, policies and programs will protect the environment and will not have any adverse impacts on natural resources or the aesthetic qualities of the community. SURROUNDING LAND USES AND SETTING Incorporated as a general law city on January 27, 1956, the Town of Los Altos Hills is located in Santa Clara County directly west of the City of Los Altos. It is encircled by the City of Palo Alto along the north and northeast boundaries. Open space preserves managed by the Midpeninsula Regional Open Space District are located along the western boundary, and unincorporated areas of Santa Clara County are located to the east. The Town encompasses approximately 8.4 square miles with an additional 5.7 square miles of unincorporated land adjacent to the Town's boundaries designated as being within its sphere of influence. The Town is bisected by Interstate 280, which runs from northwest to southeast. The Town is also served by Foothill Expressway, which forms part of its northeasterly boundary. Arterial roads including Page Mill, Arastmdero, and El Monte -Moody Road provide channels for primary movement within the Town. Characterized as a semi -rural hillside community with rolling bills and picturesque valleys, the Town serves as a transition area between the urbanized mid -peninsula and the open foothills of the coastal mountain range. The Town is a low-density suburban residential community on hilly terrain, with dense vegetation including many oak trees and natural habitats. Although Los Altos Hills is not an agricultural community, the rugged physical characteristics of the area have helped to maintain its semi -rural quality. Minor agricultural pursuits including orchards and vineyards are common. Many residents keep domestic animals, primarily horses, on their properties, adding to the semi -rural character of this community. The basic land use categories are residential, institutional, recreation, and open space. There are two zoning districts for all properties in Town: R -A (Residential Agricultural) and OSR (Open Space Reserve). Additional uses such as public and private schools, churches and synagogues, and recreational clubs are permitted through conditional use permits. There are no commercial or industrial centers. Commercial, retail, and industrial uses are found in adjoining suburban communities. Many services to the Town's population including retail stores, post offices, banks, and medical services are available in adjacent communities such as the City of Los Altos and the City of Palo Alto. Other public agencies whose approval is required: None The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a "Potentially Significant Impact" as indicated by the checklist on the following pages. ❑ Aesthetics ❑ Agriculture Resources ❑ Air Quality ❑ Biological Resources ❑ Cultural Resources ❑ Geology /Soils ❑ Hazards & Hazardous Materials ❑ Hydrology / Water Quality ❑ Land Use / Planning ❑ Mineral Resources ❑ Noise ❑ Population / Housing ❑ Public Services ❑ Recreation ❑ TransportnioNTraffic ❑ Utilities / Service Systems ❑ Mandatory Findings of Significance This Initial study has been prepared in accordance with the California Environmental Quality Act.

On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE 0 DECLARATION will be prepared. 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 the mitigation measures described on an attached sheet have been added to the project. 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 significant effect(s) on the environment, but at least one effect I) 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, if the effect is a "potentially significant impact" or " potentially significant unless mitigated." An ENVIRONMENTAL IMPACT REPORT is required, but 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, there WILL NOT be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately ❑ in an earlier FIR pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier FIR, including revisions or mitigation measures that are imposed upon the proposed project.

The Land Use Element and the Circulation Element describe the basic framework for the physical development of the Planning Area. The Land Use Element establishes guidelines for the general distribution and extent of the uses of land. The Circulation Element provides for the flow of people and goods within the Planning Area. 102. The basic land use categories dealt with in this element are residential, institutional, commercial/industrial, and public utilities. Each of these land use categories is covered in a section setting forth objectives, principles, standards, and a description. Open space and recreation proposals are dealt with in separate elements. The following sections dealing with land use proposals have been developed based on the following general land use objectives and principles: GENERAL OBJECTIVE: To provide, amidst open spaces, residential uses and the minimum public and private facilities and services necessary to serve Town residents on a continuing basis. Such facilities and services as are available from sources outside Los Altos Hills should not be duplicated within the Town. GENERAL PRINCIPLE: 103. 1. Uses of land should maintain the rural atmosphere, minimize disturbance to natural terrain, minimize removal of the natural vegetation and create the maximum compatibility of development with the natural environment through site design, architecture and landscaping. 2. In addition to single-family residences, uses within the Planning Area should include: Town of Los Altos Hills General Plan Land Use Element Page 1 of 20 103. 2(cont.) a. Those uses normally accessory to dwellings in a rural area: small-scale crop and tree farming keeping of horses and other domestic animals, and other agricultural pursuits that are compatible with residential uses; b. Those private and public park and recreational uses necessary to conveniently serve the residents; c. Those few public and private services and facilities including schools, churches, fire stations, community centers, etc., needed locally to serve Town residents. 3. Large non-residential structures should be subjected to architectural review to insure compatibility with the residential character of the community. Residential Areas Objectives: 104. 1. To maintain the rural atmosphere associated with established residential areas of the community and to ensure a similar atmosphere in future residential developments. 2. To assure that all residential development occurs in a manner minimizing disturbance to natural terrain, vegetation and wildlife and maximizing preservation of natural beauty and open space. Principles: 105. 1. Within incorporated Los Altos Hills and its Sphere of Influence dwelling types should be limited to single-family detached residences. 2. The minimum parcel size should be one acre. 3. The number of dwelling units permitted should decrease as the steepness of the land increases. 4. Residential densities should be guided by considerations of topography, vegetative cover and significant physical limit action inherent in the natural environment. Town of Los Altos Hills General Plan Land Use Element Page 2 of 20 105. (cont.) 5. Steep slopes, canyons, ravines, natural swales and drainage kept Gee of structures and left in a natural condition with respect to terrain and vegetation. These areas are classified as 'open space conservation areas". In open space conservation areas, the intensely private or semi -private recreation uses are appropriate, with drainage and erosion control measures undertaken where necessary. *Net lot area is the acreage remaining after deductions are made for public or private roads, driveway easements serving more than one lot, and park or any other land dedications. Town of Los Altos Hills General Plan Land Use Element Page 3 of 20 channels, and geologic hazard areas within areas designated for residential development should be left undisturbed and preserved as open space. 6. Limits on the development of individual residential lots shall be determined based on evaluation of such factors as natural vegetation, topographic characteristics, and soils and geology. 7. The natural character of the ridges should be preserved to the maximum extent feasible. Standards: 106. 1. Within those areas designated for "very low to low density" residential use, net lot area* should be not less than one acre, 43,560 square feet, per dwelling unit. In addition, the average net lot area for this residential category in subdivisions should increase with an increase in average slope, based on the following slope - density standards: Average slope of land to be subdivided Average net lot size 0 — 10% slope one acre 10 — 50% slope An increase from one to seven acres, based on the average slope of the land Over 50% slope Areas of such average slope should generally not be developed for residential purposes 2. Within the residential portion of the community, all slopes, canyons, and ravines, generally in excess of 30% slope should be kept Gee of structures and left in a natural condition with respect to terrain and vegetation. These areas are classified as 'open space conservation areas". In open space conservation areas, the intensely private or semi -private recreation uses are appropriate, with drainage and erosion control measures undertaken where necessary. *Net lot area is the acreage remaining after deductions are made for public or private roads, driveway easements serving more than one lot, and park or any other land dedications. Town of Los Altos Hills General Plan Land Use Element Page 3 of 20 106. (cont.) 3. Within those areas designated for "Low to medium density" residential use, existing density patterns should be preserved. In addition, the minimum lot area for this residential category in the area immediately adjacent to Los Altos Hills should be no less than one-half acre. Description: 107. Residential areas of low intensity are the predominate land use proposed in this General Plan. Two categories of residential intensities are indicated on the Plan Diagram: very low to low, and low to medium. The very low to low density residential category, for dwelling units on sites of one acre or more, is applied to areas of existing development on moderately steep to steep topography, slopes ranging generally from five to thirty per cent (5%-30%). Residential areas designated low to medium density for intensities greater than one dwelling unit per acre, are outside the corporate limits of Los Altos Hills and beyond its sphere of influence and reflect existing "flat land" development. More rugged ridge and valley areas to the west and southwest are designated OPEN SPACE PRESERVE, and are not intended primarily for residential use. (See the Open Space Element for further description of this land use category). 108. Superimposed upon the residential land use areas on the Plan Diagram is a symbol representing open space conservation areas. Within these areas special measures should be taken to conserve the cultural quality and avoid environmental problems. Residences should be placed on the more buildable lands and carefully sited so as to preserve existing trees, other vegetation and wildlife habitat areas of critical importance. The Open Space Conservation areas as private permanent open spaces can accommodate a limited variety of recreational uses suited to the natural terrain such as riding and hiking trails, scenic walks, and picnic and informal recreational activities. In many instances, these open spaces would be ideal locations for public trails and paths. In already subdivided areas, programs to assure retention of these open spaces will require the Town of Los Altos Hills General Plan Land Use Element Page 4 of 20 108. (cont.) interest and cooperation of residents. The value of insuring these open spaces accrues largely to the adjoining property owners. 109. The residential area of very low to low density is divided into six residential units for ease of handling data and descriptive material (See Map following page). The 1970 housing units and the holding capacities of each residential unit are shown in Table 1 below. The building capacity has been estimated by applying slope density standards recommended above to undeveloped lands and taking into consideration existing development. These figures represent projected total holding capacity of Los Altos Hills and its sphere of influence, assuming no further residential development of the area designated as Open Space Preserve. The holding capacity figures range from low to high, depending on the assumed number of persons per housing unit, the low representing 3.4 persons per unit, and the high representing 3.8 persons per unit.

In the following sections, each residential unit is described separately. The residential proposals are general in nature, and it is anticipated that to ensure that General Plan objectives are attained, each Town of Los Altos Hills General Plan Land Use Element Page 5 of 20 110. (cont.) future proposal for residential development will require specific analysis. Due to the unique characteristics of the planning area, topographic, geologic and drainage evaluation will be of critical importance, not only for evaluation of specific residential proposals, but for review of all land use proposals. Residential Unit No. 1 l 11. This residential unit consists of lands that make up a large portion of the Matadero Creek Basin. The area is bounded by Stanford lands to the north and northwest; the City of Palo Alto to the west; Interstate #280 to the east; and a line formed by parts of Elena and Natoma Roads, Charles Avenue, a portion of Matadero Creek and Altamont Road to the southwest acid south. As in the remainder of the community, the character of the topography of this unit is a result of the irregular drainage pattern. Existing development has tended to avoid the more rugged canyons and steep hillsides. In addition, residential areas have developed on long cul- de-sac roads due to topographic limitations and through -road connections. 112. It is proposed that all future residential development be very low to low density, and ravines and canyons associated with Matadero Creek and the Page Mill Road corridor be preserved as open space, with housing units placed on flatter land— more suitable to development. It is proposed that access also be a key consideration in development, including provision for needed emergency road connections. (See Appendix #1). 113. Large, open and undeveloped parcels along Interstate 280 in this unit provide a particularly important visual identity to Los Altos Hills. These sites should be developed carefully to ensure that their basic visual quality is not destroyed. Portions of these sites may be desirable for public purchase, or preservation through other means. 114. Interstate 280 poses serious noise problems, especially at the interchange with Page Mill Expressway. Measures to reduce the noise impact and to enhance the visual quality of the general vicinity of the interchange are needed. Several large parcels of land in this area Town of Los Altos Hills General Plan Land Use Element Page 6 of 20 114.(cont.) are in the development process and others may be developed in the near future for residential uses. The rugged character of much of the land within this unit, however, may push ultimate development to the relatively distant future. Residential Unit No. 1 is currently developed to approximately one third of its building capacity. Residential Unit No. 2 115. Residential Unit No. 2 currently has the greatest percentage of existing development in relationship to potential holding capacity, nearly seventy per cent (70%). This Unit is bounded by Palo Alto on the north; Interstate 280 to the west and southwest; Los Altos to the east; and El Monte Avenue to the southeast. As a result of its proximity to adjacent communities— this Unit is most conveniently served by auxiliary commercial areas and other existing services and facilities. 116. Fremont Hills Subdivision is the largest single development within this unit and accounts for a large portion of the existing population. 117. Development of the remainder of this Unit should be very low to low density and compatible with existing development. Where still possible, stream canyons should be preserved as open space. In addition, emergency road connections are proposed to be completed where necessary. As a result of this Unit's relatively gentle topography and proximity to existing services and facilities, it is assumed that the remaining vacant Ind will be developed in the relatively near future. Special attention will need to be given to flooding problems between Fremont Road and Manuella Road, and to the need to preserve some parcels of land for open space. Town of Los Altos Hills General Plan Land Use Element Page 7 of 20 Residential Unit No. 3 118. Residential Unit No. 3 is shown in the very low to low density residential land use category. This Unit is bounded by Elena and Natoma Roads, Charles Avenue, and a portion of Matadero Creek to the north and northwest; Altamont Road to the southwest and south; and Interstate 280 to the northeast. In general, the development of remaining vacant lands within this Unit should be accomplished with relative ease. Some problems, however, will be encountered in dealing with lands adjacent to significant drainage channels, and in development of lands immediately adjacent to Interstate 280. 119. Tributaries of Adobe and Purissima Creeks drain through this Unit into their main stream channels east of the Freeway. Associated with these tributaries are canyons and ravines densely covered with natural vegetation. These areas have been designated Open Space Conservation areas on the Plan Diagram and should be left largely undisturbed when development occurs. This will require carefully designed subdivisions and siting of structures on existing building sites. 120. Noise from Interstate 280 is a significant factor in residential development of parcels adjacent to the freeway. Careful planning will be necessary when these parcels are developed to ensure that new living environments are compatible with the objectives of the General Plan. Residential Unit No. 4 121. Residential Unit No. 4 is bounded by Altamont Road on the north; the City of Palo Alto to the west and southwest; and Moody Road to the south and southeast. This residential unit includes Byrne preserve, an Open Space Preserve in pubic ownership. Very low to low density residential use is proposed for this residential unit, due to steepness and irregular character of terrain; however, precise planning, particularly for the area west of Byrne Preserve, is essential. Town of Los Altos Hills General Plan Land Use Element Page 8 of 20 122. The portion of this Unit west of Byrne Preserve is composed primarily of the area commonly known as the MMCP area. (The term MMCP refers to the area bounded approximately by Moody Road, Moody Court, Central Drive, and Page Mill Road). This area is extremely rugged and has developed with long cul-de-sac roads lacking emergency connection routes. As a result of the complexity of this area, it is proposed that a specific plan be prepared and adopted to deal with its unique problems. The existing MMCP area plan prepared in 1972 but never adopted should be reviewed, modified where necessary, and adopted to serve as a guide for development in the area. 123. Residential development east of Byrne Preserve should be compatible with existing residential use. Development of the steep slopes with extensive natural vegetation cover north of Moody Road should be carefully planned to minimize grading and tree clearance. Specific review will be required to ensure that General Plan objectives are attained. Residential Unit No. 5 124. Residential Unit No. 5 is shown in the very low to low density residential land use category. Future development should be compatible with existing development. It is anticipated that, in general, remaining development will be accomplished easily. Factors that will require careful analysis at the time of development review are noise from Interstate 280, drainage, particularly as associated with Hale Creek, and emergency road connections, primarily those associated with Hilltop Drive and Dawnridge Road. Town of Los Altos Hills General Plan Land Use Element Page 9 of 20 Residential Unit No. 6 125. Residential Unit No. 6 is located near the southeast corner of the planning area. This unit is bounded by Moody Road and EI Monte Roads to the north and northwest; Interstate 280 to the northeast; lands of the Roman Catholic Church to the east and south; and extends to near Ewing Hill Ridge to the southwest. This Unit is designated for very low to low density residential, and it is anticipated that development of vacant parcels will be consistent with existing development. Canyons and ravines with dense natural vegetative cover should be left open and have been designated Open Space Conservation Areas on the General Plan Diagram. In addition, residential development will require careful planning, including detailed information on geology and drainage, particularly in the Olive Tree Lane area. Emergency road connections are also important in planning for residential development within the area. 126. Geologic analysis will be particularly important in evaluation of subdivision proposals within this Unit. It is anticipated that as more detailed geologic information becomes available, minor modifications to the general boundary between the residential very low to low density use and the open space preserve to the south may be appropriate. It is not anticipated, however, that modification will significantly increase the amount of acreage available for residential use; in fact, new geologic information may well indicate additional geologic hazard areas that should be avoided in development. Modifications that would be deemed appropriate would. be those for adjustments to make best use of the geologically stable lands within a particular site proposed for subdivision (any such adjustments that are proposed will have to be evaluated to ensure General Plan objectives are attained). Open Space Conservation Areas, that have been in part defined based on existing Town of Los Altos Hills General Plan Land Use Element Page 10 of 20 126. (cont.) geologic information, may also be appropriate for similar modification when new, more detailed geologic information becomes available. 127. The Neary Quarry presents significant problems to this area in terms of trucking, noise, dust and aesthetics. The quarry is shown as an open space preserve, an indication that it most likely will only be suitable as open space. Plans would need to be developed to enhance the site. Other Residential Areas 128. In addition to the six residential units, there are several other residential areas, portions of which are included within the planning area. These areas, although in other jurisdictions, are of direct and immediate concern to the planning area because of common problems relating to drainage, circulation, public facilities, and visual amenities. 129. That portion of Los Altos within the planning. area is shown in the low to medium density residential intensity category. This designation is based on existing development and plans of Los Altos. It is proposed that development of existing vacant land immediately adjacent to Los Altos Hills be no more intense than one-half acre per dwelling unit, to help provide a gradual transition between residential intensities, as previously agreed to by the City and the Town. 130. The land use intensities indicated for -those. portions of Palo Alto and unincorporated lands of Santa Clara County within the planning area reflect existing development and the plans of each of these jurisdictions. Institutions Objectives: 131 1. To provide for those institutions that are for the use of local residents and of a character in harmony with the residential character of the community. Town of Los Altos Hills General Plan Land Use Element Page 11 of 20 2. To ensure that institutions are conveniently served by traffic ways and an efficient network of trails and paths. 3. To ensure that institutions will be properly related to adjacent land uses. Principles: 132. 1. Space should be provided for only those institutional uses that may be necessary to serve local residents, such as elementary schools, churches, Town governmental buildings, and fire stations. 2. Major community facilities should be served directly by collector, or where possible, arterial roads. Emphasis should be reasonable convenience. Prime consideration should be compatibility with adjacent land uses and with preserving the rural atmosphere and existing residential character of the Town. 3. Schools should make recreation areas and facilities available for use during non -school hours. 4. The Town should work with school districts in design and development of schools to provide for Town needs in re-creation, meetings, etc. 5. School service areas should be defined so as to minimize the opportunity for conflict between children traveling to school and motor vehicles moving within and to and from the community. 6. Public buildings; should be of a size and scale conducive to maintaining the rural atmosphere of Los Altos Hills.The architectural design of non-residential buildings should be more similar to and compatible with residential buildings. Standards: 133. 1. PUBLIC SCHOOLS a. Palo Alto Unified School District --Optimum Elementary School size (K-6): 500-600 students, 10 usable acres b. Los Altos Elementary School District -Optimum Elementary School size (K-6): 500 students, 10 usable acres Town of Los Altos Hills General Plan Land Use Element Page 12 of 20 c. Mountain View -Los Altos Union High School District -- All high school students originating in Los Altos Hills are accommodated outside of the planning area -- this district believes that ultimate development of Los Altos Hills based on the holding capacity projections can be accommodated on this basis. Description: 134. The minimum institutional facilities necessary to serve the residents of the planning area are indicated on the Plan Diagram and are located as to preserve the basic residential character and rural atmosphere of the planning area. The institutions that presently, and/or may in the future, require space within the community include schools, churches, fire stations, and Town government. Schools Palo Alto Unified School District 135. Based on the holding capacity and standards for ratio of K-6 students per housing unit of the area within the Palo Alto Unified School District, an additional elementary school is proposed, in addition to the district schools presently serving Los Altos Hills residents. (Palo Alto Unified School District has for several years reserved three parcels owned by the district within Los Altos Hills for future school sites. In the fall of 1972, these sites were put up for sale by the School District. The reasoning behind this move is the belief by the School District that residential development in the foothills is no longer expected to be of such magnitude, due to the re -zoning of 6,100 acres of the Palo Alto foothills to ]0 -acre minimum lots, substantially limiting the number of students who might live in the area.) Based on the holding capacity figures, it is proposed that a portion of the site on Page Mill Road be reserved for potential elementary school development. If Palo Alto Unified is unwilling or unable to keep this parcel for a future elementary school site, the Town should consider purchasing the site. In addition, a community recreational facility is Town of Los Altos Hills General Plan Land Use Element Page 13 of 20 135. (cont.) needed in this portion of the planning area and this site could serve to fill two important needs. If the site were to be used for a school or a recreational facility, the extension of Lupine Road to Elena Road would be highly desirable and is proposed as part of this plan. (See Circulation Element). Los Altos Elementary School District 136. For the area covered by the Los Altos Elementary School District, the holding capacity and ration of K-6 students per housing unit indicates that the existing three schools, Bullis, Purissima, and Eastbrook, would be needed, and, in addition, one other site might be required if full holding capacity development occurs. District plans have indicated that one or more sites might be closed. It is proposed that the Town encourage the School District to refrain from making a final decision until further information on family size and population trends can be evaluated. If any of the schools are closed, it is proposed that the properties be retained as neighborhood or community recreation areas. However, this should only be considered after the Town is assured that the community educational needs will still be adequately met. Mountain View -Los Altos Union High School District 137. The district plans to handle the increased enrollment at full holding capacity at sites outside the planning area. No sites are proposed within the planning area. This appears consistent with Town policy for limited services within the area. Foothill Junior College District 138. It is proposed that no further expansion of District facilities occur within the Los Altos Hills Planning Area beyond those which can be reasonably accommodated on the existing college site. Daytime enrollment in 1971 was 5,600 and total evening and daytime enrollment approximately 9,100. Projected 1970-80 increase in total enrollment is a maximum of approximately 15,600. It is Town policy to work closely with the District to ensure enrollment is held to a reasonable level, Town of Los Altos Hills General Plan Land Use Element Page 14 of 20 138. (cont.) particularly with regard to the proposed circulation system to serve the college. Private Schools 139. Four private schools are shown on the Plan Diagram. The schools include Ford Country Day School, Happy Hours School, Mt. Helen Summer Home, and St. Nicholas School. Residential private schools are proposed. Town Government 140. With the possible doubling of the Town population to full holding capacity, Town Hall facilities, already constructed, could become inadequate for necessary Town administrative activities. If Town services are to be maintained even at the present minimum, expansion of administrative facilities will have to be accomplished. While the present Town Hall site can accommodate immediate expansion needs, subsequent needs will be difficult to meet, depending on the range of services desired, without crowding this long narrow site. Relevant to this problem is the need to decide where corporation yard type equipment will be stored. 141. The Town should evaluate future Town Hall needs in relationship to the range of services that potentially could be desired, and as appropriate, consider alternative, centrally located sites for Town Hall. Sites such as all or part of the vacant parcel across Fremont Road from the present Town Hall or the Bullis School site, if closing of the school is determined necessary, could be appropriate. Both of these sites are well served by circulation facilities. It is possible existing Town structures could be moved to these sites. 142. Incorporated with any expansion of Town Hall space should be provided for a few additional community serving facilities. Room should be provided for at least one public committee room apart from the Council Chambers and for a Town library. The library would at least facilitate public access to public documents and storage and display of historical documents and artifacts relevant to the Town's history. These added Town of Los Altos Hills General Plan Land Use Element Page 15 of 20 142. (cont.) facilities would not necessarily mean a change in the level of services provided; however, they would help enhance community identity and citizen involvement. 142.1 Residents of Los Altos Hills accord the highest value to the Town's open space and recreation areas. These areas, many of which are owned by the Town itself, help supply and preserve the unique character and semi -rural atmosphere of Los Altos Hills, provide important balance to the more densely urbanized San Francisco Bay plain, and provide numerous recreational, scenic, open space, and conservation resources and opportunities for the Town and its residents. As required by Principle 1 I of the Open Space Element and Principle 8 of the Recreation Element, the lands owned by the Town of Los Altos Hills commonly known as Byrne Preserve, Central Drive, Juan Prado Mesa Preserve, O'Keefe Property, Rhus Ridge Properties, Murietta Ridge, Little League Fields on Purissima Road, Westwind Community Barn, and Edith Park shall not be conveyed, sold or abandoned in whole or in part for any purpose, except pursuant to a vote of the Town electorate; provided, however, that this paragraph shall not require a vote of the electorate for any conveyance by the City of a leasehold, easement, or other property interest in these lands for a use consistent with the property's General Plan designation. Fire Protection 143. In addition to the existing fire stations, of the Los Altos County Fire Protection District shown on the proposed Plan Diagram, a proposed new fire station is shown new the intersection of Horseshoe Lane and Arastradero Road. This location has been acquired by the Los Altos Fire Protection District to enhance fire protection to the northwestern portion of the Town. Town of Los Altos Hills General Plan Land Use Element Page 16 of 20 144 Other proposals to facilitate fire protection are: a. Completion of a needed cross -tie between Elena Road and Edgecliff Road, generally in the vicinity of Lupine Road. b. Extension of Stonebrook Drive as a through road. c. Provision of emergency roads linking existing and future dead-end streets wherever it would reduce response time (See suggestions in Appendix I). d. Continue to improve the water system as part of the subdivision process. e. Require the provision of special fire protection devices for residences in areas of high fire potential, including roof sprinklers, special building materials, etc. Police Protection 145. Provision of a site to specifically accommodate a police force within the Town is not Town Policy. If, however, security problems should evolve to the point where the Town desires its own police department, there would be a need for police quarters. Even if area residents desire to establish a volunteer force to enhance contract service, space would be needed to serve the group. 146. It is proposed that in any plan for improvement of or expansion of Town Hall, consideration be given to space to meet any existing or future police quarters. Churches 147. Several churches or religious institutions are within the Los Altos Hills Planning Area. Four of these institutions, however, occur within Los Altos Hills: Poor Clare Nuns (Roman Catholic); Congregation Beth Am; the Chapel in the Hills (Episcopal); and Daughters of Charity Congregation Beth Am (Reform) and the Chapel in the Hills have conditional use permits issued by the Town, while Poor Clare Nuns existed prior to incorporation of the Town. Chapel in the Hills is the old Purissima School, an Town of Los Altos Hills General Plan Land Use Element Page 17 of 20 147. (cont.) historical building. A use permit was issued in 1970 for construction of a retirement convent for a maximum of 70 persons on a parcel of 30 acres lying between Altamont Road and Moody Road. The use, now complete, includes the administrative headquarters for the West Province of the Daughters of Charity. 148. Due to the availability of existing religious institutions, no new facilities are proposed. If it becomes obvious, however, that additional facilities are necessary, it is proposed that specific site location and development be accomplished in line with the objectives and principles of the General Plan. Commercial/Industrial Objectives: 149. 1. To encourage neighboring jurisdictions to strictly control those commercial or industrial activities that occur within those portions of their communities that are within the Los Altos Hills Planning Area in a manner that is as compatible as possible with land uses in Los Altos Hills. Description: 150. Commercial/Industrial activities occur just within the north and northeastern boundary of the planning area. These activities, however, do not occur within Los Altos Hills, nor within the Los Altos Hills Sphere of Influence. The planning area boundary includes commercial activity which occurs within the City of Los Altos and light industrial activities in the Stanford Industrial Park which is within the City of Palo Alto. 151. The residents of the Los Altos Hills area find that the commercial activities and employment sources available from sources outside the Town serve the needs of Hills residents and are reasonably accessible by major thoroughfares. Inconvenience inherent in being required to travel greater distances for everyday shopping needs or to commute to employment centers is felt to be a reasonable part of the Town of Los Altos Hills General Plan Land Use Element Page 18 of 20 151. (cont.) lifestyle of area residents. In addition, it is believed and supported by past experience in other places that expansion of commercial activities into a low density residential area would be disastrous to the existing residential character and atmosphere of the area. Public Utilities 152. Objectives: I. To ensure that public utilities will be provided in a manner that will adequately serve all residents, while minimizing the visual impact of the utilities on the community. 2. To provide for public health and safety, and to prevent biologically harmful or visible degradation of the area's natural environment in the development of public utilities. 153. Principles: All utility installations should be sited, designed, developed and landscaped so as to blend with the natural character of the vicinity. 2. Procedures that exist for the review of utility installations and/or extension should be carefully followed. In particular, each major utility should be subjected to thorough design review to assure aesthetic compatibility. 3. Power transmission lines, power distribution lines, and telephone lines should be placed underground. 4. A systematic program for the undergrounding of all existing overhead lines should be developed and implemented. 5. All new residences resulting from new subdivisions should be served by sanitary sewer trunk lines or other disposal systems meeting adequate health standards. Wherever the possibility of biological harm from septic tank use exists, requirements for conversion to sanitary sewers should be established. Standards should reflect Bay Area Water Quality Control Board and Santa Clara County Health Department requirements. Town of Los Altos Hills General Plan Land Use Element Page 19 of 20 Description: 154. To preserve the natural environment and rural atmosphere desired by the residents of Los Altos Hills, it is important that the installation and/or extension of utilities be conditioned by concerns for preventing damage to the natural beauty of the area. Standards for the extension of utilities, sewers in particular, should be based on health and safety considerations. 155. There are no problems in serving the entire area within Los Altos Hills with an adequate water supply. Purissima Hills County Water District provides service to the majority of the area with California Water Service handling the eastern and southeastern portions. In addition, trash collection, telephone service and gas and electric service are adequately provided throughout the community. Town of Los Altos Hills General Plan Land Use Element Page 20 of 20 ATTACHMENT7 Existing Pathways Element Adopted in 1996 LpSAI.TDSHILlS GENERAL PLAN OF THE TOWN OF LOS ALTOS HILLS 4...... a it C3LIFoftla PATHWAY ELEMENT (Adopted by City Council on March 20, 1996) BACKGROUND The Town's Pathways System serves three basic and important functions — circulation, recreation, and preservation of the open character of the Town. The pathway system is designed to complement the Town's roadway system and to enhance non -motorized circulation by providing connections between neighborhoods and local or nearby destinations. In this way, the Pathway Element is an integral part of the Town's Circulation Element, one of the basic General Plan elements required by State law. For the purposes of this discussion, the terms "path" and 'trail" are used interchangeably, although a'trail" generally refers to a pathway in a more natural condition or setting. The Town's pathway system is composed of roadside paths and off-road paths. Roadside paths are located within or adjacent to the road right-of-way. The road right of way is generally planned to have the needed width to accommodate both the paved road as well as a separated path. Roadside paths provide safe routes for pedestrians and equestrians in the Town, much as sidewalks function in more urban communities. Roadside paths separate the car and the pedestrian or other non -vehicular user, and allow each a safer movement. The hills of the Town result in streets which often have steep sections or blind curves, which make pedestrian separation more important than with a grid street system. Off-road paths provide links between adjacent neighborhoods and schools for pedestrians, bicyclists and equestrians. Off-road paths, which connect to roadside paths or open space lands, are generally located on dedicated easements on private property (usually along property lines), through public lands, or through privately owned conservatioNopen space easements. The Town's street system is designed to minimize the intrusion of the car into and through the Town, and cul-de-sacs are therefore common. This configuration can make it difficult to travel to nearby neighborhoods using Town roads. Off-road paths overcome this limitation by connecting neighborhoods for pedestrians and other pathway users. In addition to providing access to nearby destinations, paths provide a place to exercise, to walk dogs, or to ride horses. The primary users and beneficiaries of most of these paths are local residents. Unlike larger communities, the Town does not maintain a park system with "active" recreational uses, and instead relies primarily on the pathway network to fulfill that function. Path -related recreational activities (such as walking, jogging, hiking, bicycling and horseback riding) are among the most popular and rapidly growing forms of outdoor recreation as the public is becoming increasingly more health and fitness conscious. Pathways are frequently designed of pervious materials to maintain the Town's open and rural setting, and to further enhance the recreational experience. Both the recreational and circulation functions of the paths will become even more important as population continues to grow and as demand increases. The pathway system began to be developed with the incorporation of the Town in 1956. Early off-road paths were developed primarily for equestrian and pedestrian use. Throughout the years as each new subdivision developed and each new residence was built, the use and need for roadside and off-road paths increased. The paths have expanded incrementally along with the new developments and increased population. Each new development that adds potential new users of the system contributes to the pathway system by dedication of easements and/or construction of paths or the payment of in -lieu fees which are used by the Town for improvements of the pathway system. The system remains incomplete. Implementation of a Town -wide path system and the individual paths within it is a long term process that will take many years to accomplish. The pathway system will literally be a gHt that one generation of Town residents provides to the next. It takes a long time to complete a pathway network because paths are generally implemented one segment at a time as opportunities arise. The Town is not ever likely to have all the money that might be required to purchase all of the easements needed to develop all of the desired paths. Consequently, obtaining pathway easements and construction of pathways will continue to rely on a variety of processes, on a case-by- case basis, as opportunities arise and resources are available. Piecing together a Town -wide path system, one small segment at a time, is a difficult, time-consuming, and fragile process. Failure to obtain a few critical links in a desired pathway can disrupt the continuity of the path and thus delay, and possibly even prevent, its eventual completion. The fragility of this piecemeal process makes it all the more critical that opportunities be taken advantage of as they arise for they may not arise again for many years, if ever. GOALS G1 All residents of the Town shall have immediate access adjacent to or across the street from their residence to a pathway or pathways, for safe and convenient pedestrian and other non -vehicular travel along Town roads and to schools and community facilities, and for recreational enjoyment of the natural amenities of the community. G2 Pathways shall also serve to provide access to and from neighborhoods in the event of an emergency. G3 Pathways shall be separated from the roadway pavement and should meander, wherever possible. G4 All paths shall be located and designed to preserve the beauty and natural character of the area and to safeguard the user. G5 Except for connections to regional trail and bikeway networks, Town paths shall be designed primarily for local circulation and recreational use. POLICIES A. ROADSIDE PATHS Al Roadside paths shall be located within or immediately adjacent to the right-of-way of Town streets and on separate path easements adjacent to or over private streets. Roadside paths shall be separated from the roadway pavement by landscape buffering and shall meander, where possible. A2 The Town Council shall adopt a list of those streets or segments of those streets that shall be planned for paths on both sides of the street. A3 A roadside path shall be maintained on only one side of the street unless the street is included on the list adopted pursuant to Policy A2. The path may be located on alternating sides of the street, however, depending on factors such as available easements, topography, or proximity to schools or other facilities. A4 A roadside path shall not be maintained on a cul-de-sac that serves or could serve six or fewer lots. The traffic on such streets is deemed so minor that pedestrians can safely use the paved surface as a walkway. A roadside path along a cul-de-sac may be required by the Planning Commission or Council, however, for topographic or for safety reasons, and shall be required where it would connect to an off-road path. A5 The Planning Commission or City Council may require that an easement separate from a private street be dedicated, or that a pathway easement over the paved roadway be granted (if feasible), when the width of a private street easement of right-of-way will not accommodate both the paved surface and a separate path. AS Dedication of pathway easements outside of required road rights-of-way shall not affect the computation of the net area, LUF (lot unit factor), MDA (maximum development area) or MFA (maximum floor area) for a lot. B. OFF-ROAD PATHS 81 Off-road paths shall be located on private property on easements which have been dedicated to the Town, or over public lands. They provide connections between neighborhoods and provide direct routes to schools and open space. Cul-de-sacs should have off-road paths which connect the end of the street to adjoining neighborhoods. B2 There are three classes of Off -Road Paths: Class 1 -- Off-road paths for which easements have been granted to the Town for a completed route, on which a path has been developed or pathway use has been established, and which is maintained by the Town and is open for public use. Class 2 -- Off-road paths for which easements have been granted to the Town for less than a completed route, or where the pathway easement exists but the path has not been constructed or maintained and is not open for public use. Such paths remain to be completed in the future. Class 3 — A planned future off-road path, as shown in the Master Path Plan. These paths may need dedication of easements over a single large parcel of land, or may require easements over a number of smaller parcels. B3 Off-road paths are a permitted use in a conservation and open space easement, and should be reflected as such in the language of the easement, at the time of dedication. B4 An emergency road easement shall also include dedication of an off-road path easement. B5 The design of new subdivisions- especially those with cul-de-sac streets - shall incorporate pathway connections to nearby neighborhoods or community facilities, such as schools, and to open space areas. B6 Dedication of off-road pathway easements shall not affect the computation of the net area, LUF (lot unit factor), MDA (maximum development area) or MFA (maximum floor area) for a lot. B7 Off-road paths shall be maintained in as natural a state as possible, except that installed surfaces may be acceptable when paths serve as connectors to schools or neighborhoods, or where special use or topography make it necessary. B8 Off-road paths shall be located along or as close to property lines as possible C. REGIONAL CONNECTIONS The pathway system of the Town is intended primarily for the use of Town residents but it should be connected to the path and trail systems of neighboring jurisdictions. The Town and Palo Alto paths along Arastradero Road provide links from the Town to Arastra Preserve, to Esther Clark Park via Fremont Road, Old Trace Lane, and Aric Lane trails, and to Gunn High School via Palo Alto trails. It would be very desirable if Foothill Park (City of Palo Alto) trails were also accessible from Town paths along Page Mill Road, also allowing for connection to the Skyline Trail. Future planned access from and to Shoup Park and Redwood Grove in Los Altos, along Adobe Creek to O'Keefe Lane and the Town's path system, and a link between Fremont Road and Redwood Grove would improve pedestrian access for both cities. The western boundary of the Town meets Rancho San Antonio Open Space Preserve of the Midpeninsula Regional Open Space District. This Preserve has an extensive trail system that attracts large numbers of visitors. The primary entrance to the Preserve, where extensive parking is available, is at Rancho San Antonio County Park at the end of Cristo Del Rey Drive in Cupertino. Connections into the Preserve from the Town are intended for local residents and have very limited parking (Ravensbury Avenue, Stonebrook Avenue, La Loma Drive, Rhus Ridge Road, Francemont Avenue, Hidden Villa). Access to Open Space lands should also be pursued from Olive Tree Lane. The DeAnza trail, which Congress has designated as a national historic trail, passes through Town and should be designated on the Town's master path plan. IMPLEMENTATION OF THE PATHWAY SYSTEM A. THE MASTER PATH PLAN The Master Path Plan shall consist of all of the following: 1) A book of street maps of the Town showing streets with paths planned on both sides of the street, after adoption by the City Council (see Policy A2). 2) A book of street maps of the Town showing the side of each street on which a roadside path is planned. Determination of which side of a street the path should be located will be made incrementally by the Planning Commission, with the advice of the Pathways Committee and the City Engineer, at the time of subdivision approval or site development approval. A determination may also be made by the Pathways Committee upon the request of the City Manager or his designee, for construction or maintenance purposes. The book of street maps shall also show the status of roadside paths for cul-de-sacs and private streets, in accordance with Policies A4 and A5. 3) A book of street maps of the Town showing the location of Class 1 off-road paths. 4) A book of street maps of the Town showing the location of Class 2 off-road paths. The Pathways Committee will review from time to time these paths to determine the status of their development and to recommend actions to convert Class 2 paths to Class 1 paths. 5) A map to be developed by the Pathways Committee and approved by the City Council showing future needed off-road paths. Such a map, upon adoption, will identify Class 3 paths. Off-road paths shown on the Master Path Plan of 1981 shall remain in effect until the City Council adopts the new map, but all future paths designated by the 1981 Plan, without existing easements, shall be critically evaluated relative to function, slope, and other constraints prior to adoption of the new map. In addition to or in lieu of the documents required by 1 through 5, the Town may display the Master Path Plan through other mapping or computer data bases for public and staff use. B. IMPLEMENTATION ACTIONS 1) Development of paths shall occur incrementally as Town funds permit and as development generates increased demand and use of the system, based on resultant increases in population. Either at the time of subdivision or site development, property owners shall be required to dedicate easements and/or construct paths on their property. Owners of property on which no path is needed shall contribute by the payment of a pathway fee. The pathway fee shall be established at an amount roughly proportionate to the cost of pathway construction on the subject lot, if a pathway were required. 2) All new development which is expected to result in an increased demand for use of pathways shall comply with requirements for non -vehicular access, including dedication of easements and/or construction of paths, or payment of pathway fees, as follows: a. All subdivision development (except for lot line adjustments) shall be required to comply with pathway requirements, as the project would result in an increase in the number of homes (and residents) in the Town. b. All proposals for new main residences and/or secondary dwellings shall be required to comply with pathway requirements, as the project would result in an increase in the number of residents in the Town. c. A "cumulative" development of 900 square feet of "habitable" floor area or greater shall be required to comply with pathway requirements, as 900 square feet is considered a "major addition" requiring Planning Commission discretionary review; is generally the size of a large master bedroom and bathroom suite or three smaller bedrooms, based on typical submittals to the Town; and is roughly equivalent to the average area of floor space per Town resident, resulting in an increase (presently or in the future) in the number of residents in the Town. d. Development of a barn or stables in excess of 900 square feet shall be required to comply with pathway requirements, as the project would generate additional stable capacity and place an increased burden on the equestrian use of pathways. e. Other types of development proposals, such as conditional use permits or variances, would require a specific justification of the "nexus" for pathway requirements for that particular project. 3) Where pathway installation is required for a project, construction of the path shall occur concurrent with development of the project, unless the Planning Commission or Council determine that the path would serve no useful purpose in the near future, due to the incompleteness of the pathway segment. 4) A lot that contributed a pathway fee at the time of subdivision shall not be required to contribute again at the time of site development. 5) Pathway fees shall be deposited in a designated fund and used only for pathway projects. 6) The incremental development of the path system sometimes results in gaps in both the roadside and off-road pathways. Public funds available to the Town, including the pathway fees, shall be used on projects that will complete the gaps in the system. 7) Pathway standards shall be adopted by resolution of the City Council, to address roadside and off-road pathway design. 8) Site development authorities shall be sensitive to path location and design. This is especially the case for the off-road paths. The location shall be sensitive to the privacy of future residents whenever a parcel is subdivided or a lot is developed. All paths shall be located and designed to preserve the beauty and natural character of the area and to safeguard the user. Particular care shall be given to retaining trees and vegetative cover and to minimize grading and erosion. 9) Typically, off-road paths shall be located along property lines, when topography permits. Fencing along paths may sometimes be appropriate to protect privacy, so long as it does not intrude into easements or right-of-way. 10) Street trees along the roadside path system should be promoted to enhance the pathway experience, but shall be located to avoid conflict with path use. 11) Pathway maps showing interesting neighborhood walks should be made available so as to encourage greater use by residents. 12) Property owners who damage paths on their property shall be required to repair them. Damage can occur by landscaping planted too close to the path, sprinklers near the path, slippery driveway surfaces across a path, or disking too close to the path. 13) Class 1 off-road paths shall have sign posts at their entrance to help residents locate them and feel free to use them. 14) Major off-road paths should be named as a way to encourage their use and to recognize historical entities associated with the Town or to honor Town residents who have contributed to the development of the system. 15) The Town shall accept offers of dedication of pathway easements made at the time of development and record them so that the future pathway right-of-way is identified. 16) The Town should seek donations of path easements needed to complete gaps in the system. The Town shall assume the legal and engineering costs involved with the preparation of easement donations unrelated to development and should inform residents of possible tax advantages from easement dedication. 17) A Pathways Committee of residents interested in the pathway system shall be appointed by the Council. A major responsibility of the Committee shall be to suggest priorities for the Council and the City Manager regarding those paths most in need of maintenance or development. The Committee shall also be responsible for the maintenance and development of the Master Path Plan. 18) Property owners shall not block pathways or otherwise impede pathway use through the placement of fences, landscaping, irrigation, mailboxes, or any other means. 19) Provision for pathway crossings or bridges shall be made at appropriate locations, such as across creeks, and all roadway vehicular bridges shall be designed to incorporate pathway crossings. 20) Trails and paths shall be permitted uses in open space and conservation easements. These trails shall be constructed and maintained to minimize the environmental impact upon the area. 21) When a pathway crosses a driveway or walkway, the pathway surface shall take precedence. Where a paved surface is required, the crossing must be acceptable as a pathway, e.g., roughened. 3120196
