SPECIFIC PLAN FRAMEWORK AND COMPONENTS KIM I�9 M � 1 .11N CIN7 The goal of the Westgate Specific Plan is to implement the City of Fontana's goals and policies which are summarized in the Mission Statement identified in Section I -A of this text. This section, composed of Land Use, Circulation, Public Facilities and Community Wide / Specific Land Use Design Standards, provides the framework and E guidelines, to assure the Specific Plan implements the Mission and is "balanced and financially viable", incorporates "a mix of environmentally sound residential, commercial, public, and industrial uses ", and places an "emphasis on building an r upscale community for families and individuals ". B. SiJNWARY Westgate has been designed to take advantage of its unique freeway setting from both a regional and local context. With nearly all the approximately 257 acres of business / commercial uses near the convergence of the I -15 / Route 30 freeways, Westgate is positioned to become one of the major regional centers in the Inland Empire, and in doing so, provide a major contribution to the City of Fontana's economic and employment base. The residential areas of Westgate will benefit substantially due to their close proximity to services and employment. An extensive pedestrian and bikeway system integrates the entire community and provides an alternative to automobile travel. An equestrian trail links to the San Gabriel mountains. Approximately 32 acres of improved park uses are provided within the community, 7 acres of which are proposed within a utility corridor. Lighted ballfields, along with passive areas for informal use, picnic and children's play areas, are planned. The circulation design provides an efficient system of access throughout the site and provides a separation between many residential and business uses. Generous parkways along the major streets, entry monumentation and perimeter theme walls in Westgate provide an enhanced and inviting street scene. Architectural guidelines for the variety of land uses are provided to create unity within diversity. Together, these above elements will create a quality "upscale" environment that promotes Westgates economic potential and incorporates all the needs of its future residents and visitors: jobs, services, a variety of housing and recreation. The Land Use Section that follows generally describes the land uses that occur within the Specific Plan and includes a statistical listing that summarizes the total acres for each land use along with the total number of dwelling units, where applicable. Site specific development standards for each land use i.e., setbacks, building height limitations, are located in Section IV, Development Regulations and should be reviewed for land use requirements. The Street Circulation Section identifies all ' major streets and right of way standards within the project (a comprehensive traffic n WESMATE III 1 SPECIFIC PLAN P, Section III FRAMEWORK AND COMPONENTS study can be reviewed in the Environmental Impact Report). Bicycle circulation is also discussed in this section. Public services (water, sewer, storm drain, police and fire services) are described in the Public Facilities section. The final section, Community Wide and Specific Land Use Design Guidelines, establishes comprehensive design criteria for the various land uses in regard to 1) community wide issues i.e., community entry monuments at major intersections, streetscape themes, theme walls, and landscape guidelines seen as part of the "public landscape" and 2) specific land use design standards i.e., detailed site planning an d design standards for business parks, retail, mixed use, residential and open space / park uses. a 1. LAND USE Land uses of Westgate are summarized below and include business park, commercial retail, mixed use, residential, school and open space. The Land Use Plan, Exhibit 6, identifies the locations of these land uses within the Westgate Specific Plan. Table A on page II -1 presents a summary of the various land use acreages, including total planned dwelling units. A detailed statistical listing by planning area can be found in Table B on page III -3. The Land Use Plan is divided into planning unit areas. A planning unit area (P.U.A.) is the boundary of defined land use. Each planning unit contains a land use designation and total acres. The planning areas have generally been defined OR by logical planning boundaries, i.e. elements such as major roads, utility L corridors, etc. M a. BUSINESS PARK (BP): it Approximately 117 acres of Business Park uses have been included in the plan. These uses are generally located along the freeway and Cherry Avenue, a major highway that has direct access to the freeway. It is anticipated that for the forseeable future business park uses will be primarily distribution oriented. Over time, as the population in the surrounding area grows and the freeway is completed, a transition to light manufacturing is expected to occur. b. COMN ERCIAL RETAIL (C): Approximately 9 acres of Commercial Retail uses in two locations have been designated in the land use plan. These sites are located along major roads, providing ease of visibility and access for all local residents. Traditional retail users such as a supermarket, pharmacy, restaurant, bookstore, and / or florist are envisioned for these sites. Additional retail uses are also permitted and encouraged within the Mixed Use areas.

W. 80.90 TOTAL 954.10 2457 WESTGATE III 3 SPECIFIC PLAN Section III FRAMEWORK AND COMPONENTS c. MIXED USE (MU): Approximately 130 acres of this land use type are located generally along the intersection of the existing I -15 and Route 30 freeway.. The intent of the Mixed Use zone is to allow a variety of compatible uses and facilities supportive of the general community. These uses include retail, business park, and professional offices. Currently, approximately 75 acres are envisioned for office park within P.U.A.s #23, 33, and 34, with the balance geared toward regional and community retail / business uses. (See Exhibit 6). Any development application submitted for this land use will be required to be consistent with the varied uses permitted in the City's General Plan and as specifically defined in this Specific Plan. d RESIDENTIAL: Residential land use categories located within the Specific Plan are described below. These land use categories provide for a variety of housing within the community that will offer a diversity in house style and size. Low Density (SFD): The Low Densi ty residential land use encompasses approximately 412 acres, providing for the development of single - family detached homes " with minimum 7,200 square foot lots; 6,200 square foot with an �r extraordinary amenity, if approved in the future subject to a Specific Plan Amendment or Development Agreement. Medium High (MH): This Medium High residential land use encompasses approximately 79 a acres. A total of 474 dwelling units could be achieved in these areas dependent upon specific circumstances relative to all development standards. This designaon permits single - family detached dwellings units up to 6.0 units per acre. No apartments or attached homes are permitted. e. OPEN SPACE USES: Approximately 116 acres of the site is devoted to open space uses which are described in greater detail within the Community Design Guidelines later in this section. Open Space has been. divided into three sub - categories as follows: WESTGATE III 4 SPECIFIC PLAN I� [-I Section III FRAMEWORK AND COMPONENTS Open Space / Park (OS / P): Five planning units comprising 32.0 acres have been designated for park use. (7 of these acres are located within a utility corridor- See Exhibit 27.) Active and passive uses are currently planned for park areas. The total parks program provided meets the City of Fontana standard of three acres of park per 1,000 population for neighborhood parks. These parks are centrally located to surrounding residential neighborhoods. Community park needs of two acres per 1,000 population are planned to be met by providing community level improvements within the Westgate parks equivalent to City park fees. This will fulfill the City of Fontana standard of five acres of park per 1,000 population.* E' The total park land / improvements provided by Westgate fulfills the City of Fontana and State of California Quimby Act Park requirements as defined below: WESTGATE SPECIFIC PLAN III 5 Total maximum dwellings 2457 Person(s) per dwelling 3.48 (per City policy) Total Population 8550 Neighborhood park required at 3 acres per 1,000 population 25.0** Community park required at 2 acres per 1,000 population 16.35 ** 4135 acres total Note In the event fewer housing units are developed, the park requirements will be adjusted proportionately. * Exact park improvements will be based on City program costs unless further clarified in the Westgate Development Agreement, if applicable. Fees in lieu of construction may be paid to satisfy the patio requirements. WESTGATE SPECIFIC PLAN III 5 C Section III FRAMEWORK AND COMPONENTS - " ** The actual totals are 25.65 and 17.10 respectively. However, 82 dwelling units from the West End Specific Plan have been shifted into the Westgate Plan at the request of the City of Fontana. These units have already contributed fees to the city park requirements and their equivalent park requirements of 1.40 acres have been deducted from the total Westgate park requirements. (.65 acres have been deducted from the neighborhood parks and .75 from community parks, for a total of 1.4 acres). Public / Utility Corridor (P / UQ: Traversing diagonally through the project site is a utility corridor including Southern California Edison and Southern California Gas Company easements and a Metropolitan Water District fee simple right -of - way. This 91 acre area will largely remain unimproved open space except for the 7 acre landscape / park area and a regional bike route / trail along residential areas as shown in Exhibit 30A. Open Space / Pedeshian and Bicycle Paths / EquestrianTrail: Over seven miles of bicycle paths and pedestrian walks interconnect all parts of Westgate and provide access between the business park / employment uses and residential areas of the Specific Plan. They also provide a link to opportunites in the local surrounding area. An equestrian trail, located along the improved San Sevaine Wash Channel, provides continuous access to the San Gabriel mountains. f. SCHOOL USES (ES): A 10.0 acre school site is planned to meet the elementary school needs of the community and is located adjacent to park site planning areas 25, 26 & 31 totalling 17 acres. Junior high and high school needs will be met by existing or future planned facilities in close proximity to Westgate. The elementary and junior high school are located within the Etiwanda School District, while the high school is located within the Chaffey Joint Union District. Exhibit 6A, Public Facilities Plan, identifies the school and park sites within the Specific Plan; Exhibit 27 illustrates the school / park site design concept. 2.
