The City Council of the City of Tustin does hereby ordain as follows: Section 1. FINDINGS The City Council of the City of Tustin finds and determines as follows; A, The former Marine Corps Air Station (MCAS) Tustin was officially closed on July 2, 1999 as a result of recommendations by the Federal Base Closure and Realignment Commission. B, The City of Tustin approved a Reuse Plan in October 1996, that was subsequently amended by an Errata in September 1998, and which provides for future land uses at the former MCAS Tustin and an approximate 4.1-acre immediately adjacent parcel currently owned by The Irvine Company. C, On January 16, 2001, the Tustin City Council adopted Resolution 00-90 that certified the Joint Final EIS/EIR for the Disposal and Reuse of MCAS Tustin, and adopted Resolution 00-91 that adopted General Plan Amendment 00-001 establishing a MCAS Tustin Specific Plan general plan land use designation for the Tustin portion of the former MCAS Tustin and adjacent 4.1-acre property in anticipation that Specific Plan zoning regulations would be adopted for the site. D, The Tustin Zoning Map currently identifies the zoning for the Tustin portion of the former MCAS Tustin and adjacent 4.1-acre property as Public and Institutional (P&I). Adoption of a zoning designation Ordinance No. 1257 Page 2 Eo Fo Go H, Jo K, Lo consistent with the approved Reuse Plan and General Plan Amendment 00-001 is now required. The City of Tustin has prepared the MCAS Tustin Specific Plan and proposed Zoning Map change to ensure the orderly development and improvement of the former MCAS Tustin and immediately adjacent private property consistent with the general plan objectives, policies, programs for development of the former MCAS Tustin and an approximate 4.1-acre adjacent parcel currently owned by The Irvine Company. The Tustin City Code does not currently include provisions establishing the MCAS Tustin Specific Plan zoning regulations and requirements and therefore must be amended to provide sufficient and clear guidance regarding development consistent with the MCAS Tustin Specific Plan designation within the Tustin General Plan. Section 65850 of the Government Code allows the City to adopt ordinances that regulate the use of buildings, structures, and land; the intensity of land use; and off-street parking and loading. This Code Amendment is necessary to protect the health, welfare, safety, morals, comfort or general welfare of the citizens of Tustin and the community vision for the City by providing permanent regulations for the former MCAS Tustin site. The Planning Commission, at a public hearing that was duly noticed, called, and held on Zone Change 02-006 on October 28, 2002, approved Resolution No. 3848 recommending that the City Council adopt Zone Change 02-006. A public hearing was duly called, noticed, and agendized for consideration of Zone Change 02-006 by the Tustin City Council on December 2, 2002, but the matter was continued until January 21, 2003. On January 21, 2003, a public hearing was held on Zone Change 02-006 by the Tustin City Council. Proposed Zone Change 02-006 which includes a Zoning Map Amendment and Amendment to the Tustin City Code was evaluated in the Program EIS/EIR for MCAS Tustin. No additional environmental analysis or action is required prior to City action on the proposed project. Ordinance No. 1257 Page 3 Section 2. The City Council hereby approves Zone Change 02-006 which approves the following specific actions: , Amend the Tustin zoning map to reclassify the Tustin portion of the former MC^S Tustin and an adjacent 4.1-acre parcel currently owned by The Irvine Company from Public and Institutional to MC^S Tustin Specific Plan District (SP-1 Specific Plan) as shown on Exhibit ^ attached hereto and incorporated herein by reference. , Amend ^rticle 9 of the Tustin City Code to add Section 9246 to the Tustin Municipal Code to read as follows: 9246 MCAS Tustin Specific Plan District (SP-1 Specific Plan) a. Purpose The purpose of the MCAS Tustin Specific Plan District (SP-1 Specific Plan) is to establish zoning regulations to guide the orderly development and improvement in accordance with the MC^S Tustin Specific Plan for that portion of the city which is designated as MC^S Tustin Specific Plan on the official zoning map of the city. The preparation and adoption of a specific plan is authorized by Chapter 3, Article 8 of the State of California Planning and Zoning Law (Government Code Sections 65450 et. seq.). The MC^S Tustin Specific Plan replaces the usual development standards otherwise applicable to most property within the City of Tustin. b. Adoption of MCAS Tustin Specific Plan. There is adopted the MCAS Tustin Specific Plan, the text of which is set forth in the document entitled "MCAS Tustin Specific Plan" attached to this ordinance as Exhibit B, as corrected by changes identified as "MC^S Tustin Specific Plan Corrections" and provided as Exhibit C, which are attached hereto and incorporated herein by reference as if fully set forth herein. c. Applicability The SP-1 Specific Plan District is established by this chapter. The provisions of this section shall apply to all property shown on the official zoning map within the SP-1 Specific Plan District. The regulations set forth in the MCAS Tustin Specific Plan shall apply to the SP-1 Specific Plan District only in so far as they are not inconsistent with the Tustin General Plan. Ordinance No. 1257 Page 4 d. Permitted Uses and Development Standards All property within the SP-1 District shall be developed and maintained in accordance with all policies, requirements, regulations and provisions set forth the in the MCAS Tustin Specific Plan. e. Zoning Adoption or Change The SP-1 District zoning shall be adopted or changed by the same procedure prescribed within the Tustin City Code for zoning district amendments and consistent with State of California Planning and Zoning Law. An amendment to the MCAS Tustin Specific Plan may be processed as described within Section 4.2.7 of the MCAS Tustin Specific Plan. Amendments to the MCAS Tustin Specific Plan may be adopted by ordinance and may be amended as often as deemed necessary by the Tustin City Council. Section 3. SEVERABILITY All of the provisions of this ordinance shall be construed together to accomplish the purpose of these regulations. If any provision of this part is held by a court to be invalid or unconstitutional, such invalidity or unconstitutionality shall apply only to the particular facts, or if a provision is declared to be invalid or unconstitutional as applied to all facts, all of the remaining provisions of this ordinance shall continue to be fully effective.

The Land Use Plan contains eight (8) neighborhoods as shown on Figure 2-2. A statistical summary of the land uses contained in each Neighborhood is shown on Table 2-2. A. Neighborhood A- Learning Village Neighborhood A is located along the western edge of the site, bordered by Red Hill Avenue on the west, Armstrong Avenue on the east, Warner Avenue on the south, and an existing business center on the north. The Learning Village will be an important anchor for the community with a range of public-serving uses within a walkable campus setting. By virtue of its uses and operation, the Learning Village will be linked to many other uses and activities within the Plan area. Its primary functions are to provide education, training, and specific social service functions identified in Section 2.3.5, Public Benefit Conveyance Uses. Primary access to Neighborhood A will be from a proposed North Loop Road (extension of Valencia Avenue eastward) and Armstrong Avenue. Secondary access will be provided by Warner Avenue. B. Neighborhood B - Village Housing Neighborhood B is located in the northwestern quadrant of the site, bordered by Edinger Avenue on the north, Tustin Ranch Road on the east, the proposed North Loop Road on the south (extension of Valencia Avenue), and Armstrong Avenue on the west. Through reuse or new development of a range of housing types, Neighborhood B is expected to offer basic, affordable housing within the Plan area. The housing will be complemented by commercial village services that will meet the daily shopping needs of residents, employees and visitors to the site. The neighborhood will also have a supporting function as a transition or buffer area between existing residential neighborhoods north of Edinger Avenue and the Learning Village and Community .Core uses. Primary access to Neighborhood B will be from North Loop Road. Secondary access will be provided by Armstrong Avenue and the West Connector Road. The Neighborhood map (Figure 2-2), also identifies a shaded area within Neighborhood B that represents a conceptual design area for the future Tustin Ranch Road interchange. City of Tustin MCAS Tustin Specific Plan~Reuse Plan Page 2-12 Chapter 2 · Plan Description F. Homeless Service Providers The Base Closure Task Force in the development of the Reuse Plan for MCAS Tustin and related Homeless Assistance Submission detailed a strategy for accommodating homeless needs at the former base in both Tustin and Irvine. The Base Closure Task Force unanimously recommended (including the Task Force representative from the City of Irvine) the provision of certain family transitional housing. The Reuse Plan identified fourteen (14) units within the City of Irvine (Parcel 37) and thirty six (36) units with the City of Tustin (Parcels 34 and 35) and recommended that the Department of the Navy either: 1) convey the units to the City and then the City would negotiate the sale of the units and subsequent leasing within Tustin's jurisdictional limits to the Salvation Army (24 family traits), the Orange Coast Interfaith Shelter (6 family units) and Dove Housing (6 family units) and in Irvine's jurisdictional limits to Families Forward (14 family units); or 2) in the event that the Department of the Navy did not approve conveyance to the City, it was the desire that the Department of the Navy make a direct transfer of the units to the homeless providers. Unfortunately, the Department of the Navy rejected a portion of the Economic Development Conveyance Application for MCAS Tustin in particular the proposal to acquire the property on parcels 35 and 37 (which contain housing units). The Department of the Navy working with the General Services Administration has decided to sell the two parcels through an auction process. With this decision the Department of the Navy has also decided not to convey units directly to a homeless service provider. The decision also precludes Tustin from being able to specifically acquire and convey the 14 units within the City of Irvine directly to Families Forward. (In the case of units in Tustin, provisions in the Reuse Plan permitted homeless accommodation to be distributed on Parcels 34 or 35. The City has acquired Parcel 34). As a result of the Department of the Navy's decision on the 14 units in Irvine, the City of Tustin does not have the authority over the property, either as a property owner or as a project-reviewing agency able to condition a future development proposal, to ensure the provision of the recommended 14-units to Families Forward. It is within the Department of the Navy's or the City of Irvine's sole control and authority to make such commitments. The Department of the Navy has also taken the position that it is Irvine's responsibility to implement the Reuse Plan within its jurisdiction. Provisions of the Reuse Plan contained in gee6o~ Chapter 3 as reviewed_and recommended by the City of Irvine and as evaluated in the City of Tustin MCAS Tustin Specific Plan~Reuse Plan Page 2-57 Chapter 2 · Plan Description IRWD has expressed interest in giving up ownership of existing well properties on the northwest side of the site at Red Hill Avenue in exchange for new well sites near the site's southern border. t~: ..... '~ 8 c ...... ~, ....... ~-, ^~",~ Well sites will need to be negotiated between IRWD and the development. The exchange would provide an opportunity to develop these sites and integrate the new sites into the planned business areas. The new well sites will be used during peak periods to provide reclaimed water. City ofTust~ MCA S Tustin Specific Plan/Reuse Plan Page 2-92 Chapter 2 · Plan Description 2.17 URBAN DESIGN PLAN The MCAS Tustin site is a property of regional significance and is one of the largest remaining underdeveloped sites in central Orange County. The Plan encourages a mixed community of cutting edge technologies, research and job centers, which are integrated with learning, living and recreational uses. The purpose of the urban design concept is to achieve aesthetic integration of uses within the site and with surrounding uses in the adjacent communities. The focus is to integrate anticipated land uses with existing facilities, and provide for architectural, landscape, streetscape, and site design enhancements to improve the character of the site. The urban design concept also further delineates, in the form of standards and design guidance, the "sense of place" expressed in the Vision for the Plan (Section 1.45). The following broad design objectives are established for the Plan: To achieve architectural design of the highest quality for both new development and rehabilitation of existing structures. This includes achieving compatibility in design of infill development and creating building forms that compliment surrounding uses. To reinforce internal relationships between uses through streetscape design, pedestrian and bikeway linkages, and site planning techniques. To create a strong visual identity through design of community entries, landscape design along roadways, signage, and placement of views. · To provide usable exterior spaces within developments. To preserve existing trees and significant vegetation where feasible and integrate into landscape design. The urban design concept has been structured in levels of concepts, standards, and guidelines. When these levels are overlaid, a comprehensive design for the Plan emerges. General design intent is defined in the following sections on community structure, landscape design, and site development. Specific standards and site specific guidelines are found in Chapter 3, under each of the 22 Planning Areas. 2.17.1 Community Structure Concept MCAS Tustin's history of single use, well defined borders, framed by existing local and regional arterials lend to establishing a strong identity City of Tustin MCA S Tustin Specific Plan~Reuse Plan Page 2-117 Chapter 2 · Plan Description B. Streetscape Design- Plan Roadways All Plan roadways shall be landscaped in accordance with the following landscape details (Figures 2-20 through 2-298_). Figure 2- 19 provides a Key Map that locates each streetscape segment described below. Streetscapes shall be designed as one common landscape based on the themes developed for each roadway classification. Tustin Ranch Road and Warner Avenue Streetscape "A" (Figure 2-20). A special streetscape design should be provided for the entry segments of Tustin Ranch Road and Warner Avenue into the Plan area. The purpose is to draw motorists into the site and focus views on the formal community entry points. It is envisioned to have a formal placement of the plant material, in order to create an arrival sequence leading to the primary community entryways. This is proposed to be achieved by an upright formal planting scheme (60% evergreen, 40% deciduous). Tustin Ranch Road Streetscape "B" (Figure 2-21). Along the segment of road between the North and South Loop Road, the planting concept should be informal, and should draw upon the golf course edge and landscaped parkways to enhance the open space effect. The planting for the median and parkway is envisioned to be lush and informal design. Careful attention will be needed along the parkway to obtain the desired goal of dense planting but also create view windows into the adjacent parcels. The planting ratios are 60% evergreen, 40% deciduous. Warner Streetseape "B" (Figure 2-22). Warner is similar to Tustin Ranch Road. The planting type, mixture, and density is the same.

Ce A master sign plan is required for new development or reuse projects within the Specific Plan area involving multi-use sites and multi- tenant centers or buildings. A master sign plan is also required for the Golf Village (PA 15). The purpose of a master sign plan is to encourage coordinated and quality sign design on sites where a large number of signs will occur. In addition, the master sign plan should include on-premises directional/information signs to facilitate smooth internal circulation. City of Tustin Page 3-172 MCAS Tustin Specific Plan/Reuse Plan Chapter 4 · Specific Plan Administration There are certain planning areas that can be released without the need to initiate significant on-site or off-site Specific Plan infrastructure improvements as noted above and in the Joint EIS/EIR. However, these areas shall still bear a proportionate share of roadway infrastructure costs within the Plan and off-site. There areas are as follows: The proposed Medium-High Density Residential (MHDR) Land Use area located at the northeast comer of Edinger Avenue and Jamboree Road. · The existing residential area located between Peters Canyon Channel and Harvard Avenue north of Moffett Avenue. The proposed Elementary School (ES) and the Neighborhood Park (NP) sites located at the northwest comer of Barranca Parkway and Harvard Avenue. · The existing residential areas located between Peters Canyon Channel and Harvard Avenue south of Moffett Avenue. These areas consist of either former military housing or proposed military housing sites that can be supported by existing infrastructure. In addition to exemptions to the cumulative ADT thresholds shown in the previous table, interim uses and leases which do not result in greater ADT levels than were generated at MCAS Tustin prior to closure may be authorized pursuant to the provisions of Section 3.11.131 of the Plan. If phasing and the resulting cumulative ADTs are not consistent with the development thresholds identified in Table 4.4, a supplemental traffic study would be completed. Service providers for off-site arterial highway circulation improvements are determined by jurisdictional boundaries: the cities of Tustin, Irvine, and Santa Ana for their jurisdictions, respectively; and the County of Orange for improvements in unincorporated territory. The Transportation Corridor Agencies are responsible for the Eastern Transportation Corridor. CalTrans is responsible for freeway ramp improvements. All providers work closely with the Orange County Transportation Authority to implement the Countywide Master Plan of Arterial Highways. 4.4.5 Recreational Bikeways Additional bikeways beyond the existing system consists of one regional bikeway (Class I) and several Class II on-road bikeways. The Class I Bikeway along Peters Canyon Channel will be completed in connection with completion of channel improvements.
