Chapter 2 Project Description

2.1 Project Location The proposed project area for the Santiago Hills II and East Orange Planned Communities occupies approximately 6,800 acres at the eastern edge of the City. The proposed project area is located in unincorporated Orange County, within the City’s Sphere of Influence (Figures 2-1 and 2-2). Regionally, the area encompassing the study area is in a rural or undeveloped state and is bordered to the west by residential, commercial, and industrial developments in the City and to the southwest by unincorporated areas of Orange County and the City of Tustin. Open space surrounds the proposed project area in all other directions (Figure 2-2). Interstate 5 (I-5), State Route 55 (SR-55), SR-91, and SR-241/261 provide regional access to the proposed project area. SR-241/261 bisects the project area, with Santiago Hills II Planned Community generally west of the corridor and East Orange Planned Community generally east of the corridor.

The proposed project area can be separated into two major development areas: the 496-acre Santiago Hills II Planned Community and the 6,335-acre East Orange Planned Community. The East Orange Planned Community is made up of Area 1 planned community (East Orange Planned Community Area 1), Area 2 planned community (East Orange Planned Community Area 2), Area 3 planned community (East Orange Planned Community Area 3), and remaining areas (Figure 2-2).

The proposed Santiago Hills II Planned Community site marks the westernmost edge of the project area. The proposed Santiago Hills II Planned Community development area is generally located east of Jamboree Road, the existing Santiago Hills I development, and Peters Canyon Regional Park; west of SR-241/261; and south/east of Irvine Regional Park. The northernmost portion of the Tustin Ranch development is located approximately 1 mile south of the southern boundary of the proposed Santiago Hills II Planned Community development area.

The East Orange Planned Community is located east of SR-241/261. East Orange Planned Community Area 1 is generally located north of Santiago Canyon Road, west and south of the Santiago Canyon Landfill, and east of SR-241/261. East Orange Planned Community Area 2 is located north of Santiago Canyon Road, west and south of open space, and east of Irvine Lake. East Orange Planned Community Area 3 is generally located south of Santiago Canyon Road and east of the proposed Jeffery Road alignment. Limestone Canyon Wilderness Park is located to the southeast of East Orange Planned Community Area 3, and the Cleveland National Forest boundary is located approximately 2 miles northeast of the proposed project area.

The remaining areas comprise more than two thirds of the project area and consist of approximately 4,637 acres designated as permanent open space. These areas generally surround the development areas. These open space areas include the established NCCP Reserve, IRLR, the NCCP Special Linkage, and

City of Orange 2. Project Description

Irvine Lake. Also included within these areas is a proposed fire station along Santiago Canyon Road and a 6-acre commercial recreational location near the intersection of Jeffrey Road and Santiago Canyon Road. This location may be used as a staging area (i.e., parking and other facilities) for a riding and hiking trail. In addition, approximately 12 acres would be designated for institutional infrastructure use (see Figure 2-10, in Section 2.4.5, Overview of East Orange Planned Community). The remaining approximately 258 acres are designated for the SR-241/261 right-of-way.

2.2 Overview of Existing Setting The Santiago Hills II and East Orange Planned Communities project area consists of a series of low-lying hills and valleys on the southern flank of the Santa Ana Mountains, with the eastern part of the site being somewhat steeper and more varied than the western part. The closed Santiago Canyon Landfill is within this project area but is owned by the County and is not part of the project, except for pre-annexation general plan and zoning designations. As part of the closure, the landfill slopes will eventually be restored with native plant communities.

East of the landfill are Santiago Dam and Irvine Lake, which is an operating water supply reservoir that is fed by flows from Santiago and Limestone Canyon Creeks as well as water purchased from the Metropolitan Water District of Southern California. IRWD and the Serrano Water District own Irvine Lake and will continue reservoir operations there, including water storage and use, reservoir maintenance, and operational activities.

A 40-acre sand and gravel quarry and a concrete batch plant are located on the reservoir’s eastern margin in the Santiago Creek arm of the reservoir. A mitigated negative declaration was adopted for the reclamation plan in 1989. To increase the quality and efficiency of reservoir operations, the water districts and their subcontractors completed silt and mineral extraction activities in this area. Reclamation efforts were recently completed. In the future, IRWD may continue limited extraction activities after the departure of the existing extraction company.

IRWD, Serrano Water District, and The Irvine Company share recreation rights associated with Irvine Lake. Currently, commercial recreational uses exist adjacent to Irvine Lake, allowing for activities such as fishing and boating.

The proposed project area is bisected by SR-241/261 and Santiago Canyon Road, and is surrounded by a range of existing land uses. Extensive areas of natural open space abut the development areas, principally to the north and east. These open space areas include The Nature Reserve and IRLR. Irvine Regional Park is north of the proposed site, and Peters Canyon Regional Park flanks the area to the southwest. The western boundary of the Cleveland National Forest is approximately 2 to 3 miles east of the area’s easternmost point. Residential, commercial, and industrial developments exist in the general project area, with the City of Orange to the west, Tustin to the southwest, Irvine to the south, and Anaheim to the north.

As discussed in Chapter 1, the proposed project is located within the central subregion of the Central/Coastal NCCP/HCP and contains a variety of sensitive species and wildlife. More specifically, the project study area is within the central range County Planning Area of the NCCP. The NCCP planning process, completed in 1996, resulted in the creation of The Nature Reserve, which presently includes approximately 37,000 acres of natural open space in its central and coastal subregional reserves.

2.3 Project Objectives for Santiago Hills II and East Orange Planned Communities A statement of project objectives is required by the State CEQA Guidelines (Section 15124 [b]). In general, an objective can be defined as the purpose for which something is proposed or as some type of goal. Under CEQA, a clear statement of project objectives is important because alternatives evaluated in an EIR must achieve, in whole or in part, the underlying objectives.

An overriding goal of the proposed Santiago Hills II and East Orange Planned Communities project is to provide for the orderly development of a phased land use plan that balances the need for residential development with the preservation of open space and enjoyment of recreational opportunities. The objectives developed for the proposed project are as follows:

integrate the East Orange area into the City’s General Plan, adopting general plan and zoning amendments that establish the general framework for ultimate development within the study area; provide a comprehensive, well-rounded residential master plan for the property that addresses environmental, water quality, drainage, circulation, and community recreational needs issues; encourage excellence and creativity in the general plan and establish a community with a unique sense of identity and high quality of life; address community circulation, both vehicular and pedestrian, utilizing available capacity within the existing circulation system, and provide fair-share system improvements to deficient intersections or road segments; provide an active sports park containing lighted sports fields in this area of the City for use by the community; promote compatibility with the adjacent IRLR and NCCP open space and surrounding residential uses by allowing for development in those areas that are less environmentally sensitive so that sensitive resources can be preserved; shape a development plan for the study area that reflects the newly dedicated open space; ensure that development of the East Orange Sphere of Influence enhances the City of Orange’s housing stock by providing for-sale housing opportunities to a range of household incomes; plan for infrastructure and public services that are appropriately sized to serve the new development. designate land uses within the East Orange area that will result in a fiscal balance for the City of Orange; identify and respect significant topographical, biological, natural, and visual resources in East Orange; expand recreational opportunities and the range of support facilities by providing parks and linkages to local and regional trail opportunities; and provide the opportunity for a 150-acre 18-hole golf course facility to provide recreational opportunities and a revenue source for the City.

City of Orange 2. Project Description

2.4 Project Components

2.4.1 City of Orange General Plan Amendments/East Orange General Plan The City originally adopted the East Orange General Plan in 1989. The East Orange General Plan sets out future land use and development plans for the unincorporated area in anticipation of its eventual annexation to the City. The East Orange General Plan study area currently consists of two major components: the East Orange Planned Community (6,335 acres) and Santiago Hills II Planned Community (494 acres). An additional 2 acres of open space resulting from more accurate acreage calculations and adjustments to the SR-241 right-of-way is proposed to be added to Santiago Hills II Planned Community, bringing the total of the East Orange General Plan study area to 6,831 acres.

The 1989 adopted East Orange General Plan allows for development of more than 12,350 dwelling units at low, medium, and medium-high intensity; 359 acres of retail- and employment-related uses; 160 acres of mixed use development; and 2,165 acres of natural open space on the 6,831 acres of the East Orange study area. With the proposed amendments to the East Orange General Plan, the City’s Integrated General Plan would reflect a much reduced land use intensity for the East Orange study area, 4,096 dwelling units at low and medium intensity; no retail, employment, or mixed-use development; and more than 5,000 acres of permanent open space. As part of the proposed project, applicable policies and goals from the 1989 East Orange General Plan would be incorporated into the City’s Integrated General Plan. The proposed general plan amendment, including policies and maps and descriptive text, are provided in Appendix A-2.

2.4.2 Santiago Hills II Planned Community Components (West of SR-241/261) Project components related to Santiago Hills II Planned Community include the following:

amendment of the City General Plan to incorporate the Santiago Hills II Planned Community; amendment of the Santiago Hills II Planned Community Development Plan (approved by the City Council in September 2000 as an amendment to the East Orange General Plan) to increase the area by 2 acres (from 494 to 496) (see Table 2-1 and Figure 2-3); amendment of the County MPAH (see Section 2.4.12.1); processing of Tentative Tract Maps 16199 and 16201, including detailed lot plotting; associated infrastructure improvements; related design and landscape guidelines; supplemental fuel modification plan; review and implementation of previously adopted mitigation measures for the area; and a ROMP (encompassing both the Santiago Hills II Planned Community area and East Orange Planned Community Area 1); adoption of a conceptual landscape plan; adoption of a conceptual fuel modification plan; changes in the boundaries of residential and open space sectors from the approved Santiago Hills II Planned Community Development Plan; and adjustments to the SR-241/261 right-of-way area, based on tentative tract map-level engineering.

2.4.3 East Orange Planned Community Components (East of SR-241/261) The East Orange Planned Community is divided into the following planning areas (east of SR-241/261):

East Orange Planned Community Area 1, East Orange Planned Community Area 2, East Orange Planned Community Area 3, and remaining areas.

Project components related to the East Orange Planned Community are as follows:

For East Orange Planned Community Areas 1, 2, and 3, the project includes general plan amendments and zoning changes related to reductions in development intensity from that indicated in previously approved plans (see Table 2-2 and Figure 2-4). For East Orange Planned Community Area 1, the project includes Tentative Tract Map 16514, including detailed lot plotting; associated infrastructure improvements; related design and landscape guidelines; a sports park; a fire master plan; a fuel modification plan; and a ROMP (encompassing Santiago Hills II Planned Community and East Orange Planned Community Area 1). For East Orange Planned Community Areas 2 and 3, no tentative tract map is proposed, but general-plan-level design and landscape guidelines, conceptual grading, and ROMPs are included, as well as a fire master plan and fuel modification plan. For remaining areas, the project includes general plan designations that would allow for infrastructure, a fire station, and several commercial recreation areas, as well as designated open space.

2.4.4.1 Land Use The proposed Santiago Hills II Planned Community consists of low density residential, low-medium density residential, medium density residential, two neighborhood parks (4.7 acres and 4.4 acres, respectively), a 10-acre elementary school site, and 112 acres of dedicated open space (Figure 2-5). Figure 2-3 illustrates Santiago Hills II Planned Community’s proposed land uses, as well as the land uses that were approved in 2000 and analyzed in 2000 SEIR 1278. Table 2-1 compares the 2000 general plan designations with the proposed general plan designations. Table 2-3 estimates the size of homes and number of units by sector.

2.4.4.2 Proposed Changes The general plan land use map and zoning map designations, as detailed in the proposed project area application, are proposed to be amended as follows (see Figure 2-3):

The boundaries of Residential Sectors E, G, H, and I and Open Space Sector A have been revised (as shown in Figure 2-5) as a result of tentative map engineering and roadway modifications, resulting in a 4-acre increase in open space adjacent to Irvine Regional Park and a 1-acre increase in residential acreage. The SR-241/261 rights-of-way along the eastern edge of Sectors C, E, I, J, and K have been adjusted, subject to the approval of the California Department of Transportation (Caltrans), due to tentative- tract-map-level engineering to reflect the proposed ultimate right-of-way ownership associated with the roadway. That results in Open Space Sector C decreasing in size from 16 acres to 14 acres and Residential Sectors J and K decreasing from 134 acres to 133 acres. These amendments do not change the approved residential uses or densities in Santiago Hills II Planned Community.

Santiago Hills II and East Orange October 2004 Planned Communities Draft SEIR/EIR 2-7 J&S 03005.03

City of Orange 2. Project Description

In response to the changes to sector boundaries and areas, the dwelling units assigned to the residential sectors would be redistributed and adjusted to ensure that densities established in the 2000 Santiago Hills II Planned Community Development Plan are maintained. Circulation element amendments for riding and hiking trails would bring additional trails into the Santiago Hills II Planned Community area and would realign the planned regional multi-use trail from the location adjacent to Jamboree Road to a location inside the Santiago Hills II Planned Community area. Proposed circulation element amendments for the Santiago Hills II Planned Community roadway system are a result of the proposed reduction in development intensity in the adjacent East Orange Planned Community and refinements to the design of the tentative tract map. The previously proposed easterly extension of Santiago Canyon Road adjacent to Irvine Regional Park would be deleted, and a new local collector (Street “A”), with a different alignment, would take its place. Street “A” would form a “T” intersection on Chapman Avenue east of Jamboree Road, continue through the northern portion of Santiago Hills II Planned Community, and cross SR-241/261 with an overpass to East Orange Planned Community Area 1 as it enters the East Orange Planned Community. Proposed open space and conservation element amendments are designed to add 4 acres to the area zoned as open space at the northern boundary of Santiago Hills II Planned Community, adjacent to Irvine Regional Park. The area northwest of Jamboree Road is not a part of the current project proposal (Sector F). This area was purchased by Santiago Canyon Community College in early 2003, reducing the Santiago Hills II Planned Community portion of the proposed project area by 150 units and 25 acres. No tentative tract map has been submitted for this area. Changes to the Santiago Hills II Planned Community Trails Master Plan and the Public Facilities Concept Plan are proposed to correspond to the deletion of Santiago Canyon Road in the northern portion of Santiago Hills II Planned Community adjacent to Irvine Regional Park. A proposed riding and hiking trail system would link the community with Peters Canyon and Irvine Regional Park. This trail system is proposed to follow the revised street system through Santiago Hills II Planned Community north of Chapman Avenue, and provide an east/west connection to the future East Orange Planned Community and Irvine Regional Park. The Handy Creek/Jamboree Road riding and hiking trail segment remains a part of the revised 2000 Santiago Hills II Planned Community Development Plan, in a slightly different alignment than identified in the 2000 Santiago Hills II Planned Community Development Plan. This is discussed in more detail below. Preliminary design for this portion of the proposed project area is set forth in two proposed tentative tract maps, 16199 and 16201, that refer to the general areas south and north of Chapman Avenue, respectively. Tentative Tract Maps 16199 and 16201 depict detailed lots for conventional single- family detached and single-family attached residential neighborhoods within Santiago Hills II Planned Community. These are discussed in more detail below. Additional design features, such as water quality basins, water quality facilities, and drainage improvements have been added as part of the ROMP. A detailed description of the ROMP and all of its related facilities is in Section 3B, Water Resources. These facilities are analyzed as part of the proposed project. In addition, the City is proposing a density increase of 46 additional housing units to accommodate affordable housing in Santiago Hills II Planned Community. The City Community Development Department and The Irvine Company are currently in preliminary talks regarding Lot 340 (Sector I) of the proposed Santiago Hills II Planned Community area. The City Community Development Department is proposing to purchase or lease Lot 340 on proposed Tentative Tract Map 16201. The Irvine Company has allocated 82 units on this 3.96-acre lot. The City is proposing to subsequently purchase the lot and increase the density by 56 percent, which would add 46 units, bringing the total number of units to 128. It is estimated that 50 percent of the units would be developed as affordable

housing. The preliminary design concept of the area includes a clubhouse, a park area, and a basketball court.

2.4.4.3 Tentative Tract Maps Tentative-tract-map-level engineering shows that the Santiago Hills II Planned Community area is approximately 471 acres, of which a total of approximately 359 acres would be occupied by 1,592 residential units and the remaining 112 acres would be occupied by parks, open space, and associated infrastructure and roadways that are to be constructed.

Two tentative tract maps have been submitted for Santiago Hills II Planned Community. The maps propose a total of 1,592 units in Sectors E, G, H, I, J, and K of Santiago Hills II Planned Community. As discussed above, the City is proposing an additional 46 units that would bring the total number of units 1,638. No tentative tract map is proposed for Sector F, which is now owned by Santiago Canyon Community College.

Tentative Tract Map 16199 includes detailed lotting for conventional single-family detached residential neighborhoods in Sector J, which would be subject to design guidelines that have been submitted for approval with the proposed project area application. Figure 2-6 illustrates Tentative Tract Map 16199. The single-family attached residences in cluster neighborhoods in the remaining portions of Sectors J and K would be reviewed for consistency with the design guidelines when follow-up tract maps—showing detailed internal streets, building pads, and common areas (sometimes referred to as “B-level” maps)— are filed by The Irvine Company or merchant builders. Tentative Tract Map 16199 would have a balanced cut and fill grading operation of approximately 2,446,000 cubic yards.

Tentative Tract Map 16201 includes detailed lotting for conventional single-family detached residential neighborhoods in Sectors G and H, which would be subject to design guidelines that have been submitted with the proposed project area application. Figure 2-7 illustrates Tentative Tract Map 16201. The single- family attached residences in cluster neighborhoods in Sectors E and I would be subject to similar design guidelines that would be submitted with the application and would accompany follow-up B-level maps to be filed by The Irvine Company or merchant builders. Tentative Tract Map 16201 would have a balanced cut and fill grading operation of approximately 6,340,000 cubic yards.

Table 2-3 estimates the square footage by sector.

2.4.4.4 Design and Landscape Guidelines Formal design and landscape guidelines for Santiago Hills II Planned Community have been submitted as part of the proposed project (Figure 2-8). The guidelines contain a full discussion of the proposed neighborhood, architectural and landscape design, and proposed home types and distribution.

The application for Tentative Tract Maps 16199 and 16201 includes architectural and landscape design guidelines. As part of the proposed project area, single-family detached units would comply with the design guidelines. Single-family attached residential neighborhoods within Santiago Hills II Planned Community are intended to be reviewed for consistency with the design guidelines at the subsequent time when follow-up tract maps—showing detailed internal streets, building pads, and common areas (B-level maps)—are filed by The Irvine Company or merchant builders. Santiago Hills II Planned Community neighborhoods are to be designed as traditional neighborhoods, with a plant palate of historic Southern

City of Orange 2. Project Description

California native and nonnative species. The architectural design guidelines address the construction of dwelling units in various styles, including Spanish Colonial, Monterey, Cottage, and Mediterranean.

2.4.4.5 Fire Master Plan and Fuel Modification Plan A fire master plan has been developed to identify the specific fire prevention techniques associated with the proposed Santiago Hill II Planned Community development area. The fire master plan is intended to supplement the fuel modification plan submitted with the design guidelines for the tentative tract maps. As part of the proposed development, the fire master plan and the fuel modification plan would be reviewed concurrently with Tentative Tract Maps 16199 and 16201.

The fuel modification plan for Santiago Hills II Planned Community consists of layered zones of thinned natural vegetation and strategically placed irrigated and nonirrigated landscape between the dwelling units and the adjacent open space.

2.4.4.6 Implementation of Mitigation Measures The mitigation measures included in 2000 SEIR 1278 are part of the proposed project. Therefore, the potential impacts of implementing such mitigation measures are reviewed and analyzed as part of the proposed project. In addition, any proposed revisions to the Santiago Hills II Planned Community mitigation measures were reviewed to determine whether they are still adequate or whether changes are necessary due to the changes in the project, changed circumstances, or significant new information showing new potential adverse impacts that were not previously analyzed.

2.4.4.7 Santiago Hills II Planned Community and East Orange Planned Community Area 1 Runoff Management Plan The ROMP is intended to identify potential changes to the watershed from the predevelopment conditions of the proposed development and identify appropriate mitigation measures for the post-development hydrology. The ROMP and its associated facilities are analyzed as part of the project.

Santiago Hills II Planned Community and the majority of East Orange Planned Community Area 1 are within the same sub-watershed. Therefore, a draft ROMP was prepared for both project areas. (The ROMP and associated water quality analyses are included in Appendix B, which is being circulated with this Draft SEIR/EIR.) The sub-watershed of the eastern portion of East Orange Planned Community Area 1 that flows to Irvine Lake is included in this ROMP. Section 3B, Water Resources, describes the ROMP in detail.

2.4.5 Overview of East Orange Planned Community The proposed East Orange Planned Community is illustrated in Figure 2-9. The planned development in East Orange Planned Community Areas 1, 2, and 3 and the remaining areas consist of residential, commercial recreational, and institutional uses, as well as open space. Figure 2-4 illustrates East Orange Planned Community’s proposed land uses, as well as the land uses that were approved in 1989. Table 2-2 compares the adopted 1989 plan with the proposed general plan designations. Table 2-4 represents the

City of Orange 2. Project Description

2.4.6 Overview of East Orange Planned Community Area 1 Proposed land uses within East Orange Planned Community Area 1 are depicted in Figure 2-9. East Orange Planned Community Area 1 would consist of low density and low-medium density residential, two neighborhood parks (approximately 6 acres and 3.3 acres), a 1-acre “paseo,” and an approximately 20-acre sports park. East Orange Planned Community Area 1 is surrounded by open space to the north, south, and east that is either part of the NCCP or recently established conservation areas. The proposed land uses are similar to those designated in the East Orange General Plan, except that the proposed land uses have lower densities with larger areas of open space.

2.4.6.1 Land Uses Preliminary design for East Orange Planned Community Area 1 is set forth in proposed Tentative Tract Map 16514, which depicts the area generally east and north of SR-241 and west of the closed Santiago Canyon Landfill. Tentative-tract-map-level engineering shows that East Orange Planned Community Area 1 encompasses approximately 426 acres, with approximately 340 acres to be developed with a proposed 1,024 residential units, 10.3 acres of neighborhood parks, and an approximately 20-acre sports park.

East Orange Planned Community Area 1 includes several water quality control basins, including an 8.7-acre water quality basin in the northeastern corner. This basin, as well as other water quality and flood control features located throughout East Orange Planned Community Area 1, would be constructed as part of the ROMP. Access to East Orange Planned Community Area 1 would be provided by way of the new bridge, new collectors, and the existing local roadways in the project vicinity.

2.4.6.2 Tentative Tract Map Tentative Tract Map 16514 is located in East Orange Planned Community Area 1 (Figure 2-10). The tentative tract map includes detailed lotting for conventional single-family detached residential neighborhoods in Sectors 11 and 12 and single-family attached residential neighborhoods in Sectors 15, 16, and 17, all of which would be subject to design guidelines submitted with the proposed project area application. Follow-up B-level maps showing detailed internal streets, building pads, and common areas would also be subject to those design guidelines for architecture, setbacks, and other development criteria. Proposed Tentative Tract Map 16514 shows detailed lots for approximately 274 low-density, single- family units on approximately 81 acres. Tentative Tract Map 16514 would have a balanced cut and fill grading operation of approximately 9,190,000 cubic yards. In addition, up to 750 low-medium density single-family attached units would be constructed on 224 acres. The single-family attached residential neighborhoods would be the subject of future B-level maps by The Irvine Company or merchant builders.

2.4.6.3 Design and Landscape Guidelines As for the design and landscape guidelines prepared for the Santiago Hills II Planned Community, the design intent of East Orange Planned Community Area 1 neighborhoods is to capture the small-town feeling that has been established by the urban framework of the City (Figure 2-8). The neighborhoods would be defined by roadways (including a split lane design for Street “A”), geographic elevation changes, and designated riding and hiking trails that provide connectivity to internal and adjacent

community facilities in the Santiago Hills II Planned Community and other development areas of the East Orange Planned Community. The architectural design guidelines address the construction of dwelling units in various styles, including Spanish Colonial, Monterey, Craftsman, Cottage, California Ranch, and Mediterranean.

Similarly, landscape architecture plays a key role in defining East Orange Planned Community Area 1 neighborhoods, which are designed as traditional neighborhoods that would lend themselves to a formal planting structure with a plant palate of historic Southern California native and nonnative species.

2.4.6.4 Sports Park An approximately 20-acre lighted sports park is proposed along the southern perimeter of East Orange Planned Community Area 1 near the intersection of Santiago Canyon Road and proposed Street “A.” The sports park’s proposed location takes into consideration the interface between the sports park and adjacent neighborhoods in East Orange Planned Community Area 1, as well as ease of vehicular access from other communities in the East Orange vicinity.

A conceptual design of the proposed sports park has been prepared by the City and includes the following components: three baseball fields, two soccer fields, basketball courts, a skateboard park, an approximately 2,500-square-foot meeting room, a concession stand, several playground areas, and bathroom facilities. One of the soccer fields would also be used as a football field. Lighting would be provided for the fields to allow evening sporting activities. The park, which would provide 300 parking spaces, would operate year round. Design features would include:

a buffer between the park and proposed neighborhoods adjacent to it; a dense landscape planting zone along the park boundary, including evergreen leaf trees, coniferous trees, shrubs, and groundcovers that would provide a natural method of dust filtration, a visual buffer and backdrop to the park, and a physical barrier between the park and the proposed residential units; and lighting that would be oriented inward to minimize intrusion into the surrounding area.

2.4.6.5 Runoff Management Plan The ROMP for the Santiago Hills II Planned Community also addresses East Orange Planned Community Area 1 because both are a part of the same sub-watershed.

2.4.6.6 Fire Master Plan and Fuel Modification Plan A fire master plan has been developed to identify the specific fire prevention techniques associated with the proposed project area. The fire master plan is intended to supplement the fuel modification plan submitted with the design guidelines for the tentative tract maps. The fire master plan and the fuel modification plan for East Orange Planned Community Area 1 are being reviewed concurrently with East Orange Planned Community Area 1 Tentative Tract Map 16514. The fuel modification plan for East Orange Planned Community Area 1 consists of layered zones of thinned natural vegetation and strategically placed irrigated and nonirrigated landscaping between the dwelling units and the adjacent open space. This is described in more detail in Section 3N, Public Services.

Santiago Hills II and East Orange October 2004 Planned Communities Draft SEIR/EIR 2-13 J&S 03005.03

City of Orange 2. Project Description

2.4.7 East Orange Planned Community Areas 2 and 3 East Orange Planned Community Area 2 is located at the eastern perimeter of Irvine Lake and north of Santiago Canyon Road (Figure 2-9). East Orange Planned Community Area 2 encompasses approximately 947 acres, of which 599 acres would be planned for residential development. The land uses proposed for East Orange Planned Community Area 2 are similar to those designated in the East Orange General Plan but, in some cases, at lower densities than the general plan designations. In addition, more of the land in and adjacent to East Orange Planned Community Area 2 is planned as open space.

East Orange Planned Community Area 3 is located south of Santiago Canyon Road (Figure 2-9). East Orange Planned Community Area 3 encompasses approximately 45 acres planned for 50 low density residential dwellings. The land uses proposed for East Orange Planned Community Area 3 are similar to those designated in the East Orange General Plan, but with lower densities and more open space.

2.4.7.1 Land Uses

East Orange Planned Community Area 2 Figure 2-9 illustrates the proposed general plan amendments and zoning designations. Proposed residential land uses include low density and low-medium density residential development that would allow up to 1,200 dwelling units. The residential land uses proposed in East Orange Planned Community Area 2 would be governed by the development standards proposed in the East Orange Planned Community Development Plan. Tentative tract maps have not been prepared for this area at this time. However, general-plan-level design and landscape guidelines have been prepared. It is anticipated that East Orange Planned Community Area 2 units would bear an architectural resemblance to California Ranch and Cottage style homes. Circulation for East Orange Planned Community Area 2 would stem from Santiago Canyon Road. Specific internal circulation details would be available in the future when tentative tract maps are prepared for the area.

The remaining 348 acres would be zoned for commercial recreational uses, such as an 18-hole golf course, a marina, and a lodge/inn with approximately 100 rooms. There currently are commercial recreational uses adjacent to Irvine Lake, allowing for such activities as fishing and boating. The proposed plan anticipates the continuation of existing recreational activities (e.g., fishing, sailing, and boating), and provides an opportunity for additional recreational activities.

Four commercial recreational zones are proposed within East Orange Planned Community Area 2. The commercial recreational zones are identified as Sectors 8 and 9 on the East Orange Planned Community Development Plan. The acreage for each of the commercial recreational zones is listed in Table 2-4. The purpose and intent of the proposed project area’s commercial recreational zones is to provide for existing and future commercial uses, which focus on outdoor recreation complimentary to Irvine Lake in Sectors 8, 9A, and 9B. Sector 8 is 192 acres and is the largest of the commercial recreation zones. Exclusively reserved for Sector 8 is zoning for the following uses:

a minimum of 1.5 acres reserved for a lodge/inn with a maximum of 100 overnight accommodations; a minimum of 2 acres reserved for a marina and water-related recreational facilities, such as boating docks and fishing ponds for boating and fishing activities; and a minimum of 150 acres reserved for an 18-hole golf course open to the public.

Santiago Hills II and East Orange October 2004 Planned Communities Draft SEIR/EIR 2-14 J&S 03005.03

City of Orange 2. Project Description

Temporary uses, site development standards, and other uses permitted subject to a conditional use permit are further detailed in the East Orange Planned Community development standards.

Sectors 9A and 9B combined are 20 acres, and are located between the southern edge of Irvine Lake and Santiago Canyon Road. Permitted uses for these sectors include, but are not limited to, marinas, fishing piers, fishing ponds, boat docks, boat rentals, and similar water-related recreation facilities. Such facilities are currently located in Sectors 9A and 9B. Several permitted uses in Sector 9B are only allowed provided that the uses and construction impacts caused by such uses are located entirely within the area physically disturbed by an existing use. The commercial recreational area in East Orange Planned Community Area 2 is described under the remaining areas section, below.

The proposed commercial recreational uses are located adjacent to the northeastern boundary of Irvine Lake on the site of a mining operation. Currently, a 40-acre quarry and a concrete batch plant are located on the reservoir’s eastern margin in the Santiago Creek arm of the reservoir. Historically, sand and gravel extraction and desilting activities have occurred within and adjacent to this planning area in Irvine Lake, in the area where the inlet of Santiago Creek enters Irvine Lake and in the area where Limestone Canyon Creek enters Irvine Lake. This land is owned in part by IRWD, Serrano Water District, and The Irvine Company.

Any further recreational uses allowed on and around Irvine Lake would be determined by IRWD, Serrano Water District, and The Irvine Company. The land use plan associated with the implementation of the East Orange Planned Community shows a commercial recreation designation along portions of Irvine Lake that would allow for the implementation of a marina, boat docks, a lodge/inn, and other water- oriented uses.

East Orange Planned Community Area 3 East Orange Planned Community Area 3, located south of Santiago Canyon Road and at the eastern edge of the East Orange Planned Community area, is currently designated for rural, low-medium density residential, and open space. This proposed project area would amend the land use element to allow for 50 low density residential dwelling units only. As a result, East Orange Planned Community Area 3 would be a small rural community that is completely surrounded by the designated open space of Sector 5 in the East Orange Planned Community.

The proposed general plan and zone changes are illustrated in Figure 2-9.

2.4.7.2 Grading Concept The conceptual grading plan for the East Orange Planned Community identifies the general areas of grading. For East Orange Planned Community Areas 2 and 3, there would be approximately 18.5 million cubic yards of balanced cut and fill, which would cover approximately 644 acres (not including grading required for Sectors 8, 9a, and 9b).1 Variation in graded contours and grading volumes would be permitted, provided grading would not extend beyond the development impact area shown on the conceptual grading plan. However, grading may occur beyond the remedial grading area in open space areas for utilities, maintenance roads, recreation facilities, drainage and water quality facilities, reservoir areas, and other public facilities permitted in the open space areas (Figure 2-11).

1 No grading is anticipated for Sectors 9a and 9b, which contain existing uses. Grading plans have not been developed for Sector 8, the location of the future golf course.

City of Orange 2. Project Description

2.4.7.3 Conceptual Runoff Management Plan As part of the proposed project, a conceptual ROMP has been prepared for East Orange Planned Community Areas 2 and 3 and the remaining areas. These proposed facilities are discussed in more detail in Section 3B, Water Resources.

2.4.7.4 Design and Landscape Guidelines The development plan for East Orange Planned Community Areas 2 and 3 submitted as part of the proposed project application contains conceptual architectural and landscape design guidelines at a general-plan-level for adoption by resolution. These guidelines would serve as a framework for future construction plans and would create a benchmark for development.

Landscape architecture plays a key role in defining East Orange Planned Community Areas 2 and 3 neighborhoods, which are designed as traditional neighborhoods with a plant palate of historic Southern California native and nonnative species.

2.4.7.5 Fire Master Plan and Fuel Modification Plan In order to put the development plans into context with the City Fire Department requirements, a fire master plan would be prepared and approved with future tentative tract maps to identify the specific fire prevention techniques associated with East Orange Planned Community Areas 2 and 3. The fire master plan for East Orange Planned Community Areas 2 and 3 would address a plan for a future fire station. In addition, a fuel modification plan for East Orange Planned Community Areas 2 and 3 would be prepared and submitted with the design guidelines for these tentative tract maps.

Similar to the fuel modification plan for East Orange Planned Community Area 1, the fuel modification plan for East Orange Planned Community Areas 2 and 3 would consist of layered zones of thinned natural vegetation and strategically placed irrigated and nonirrigated landscaping between the dwelling units and the open space in surrounding areas of the proposed project area.

2.4.8 Remaining Areas A majority of the remaining areas, approximately 4,637 acres, would be designated open space (including Sectors 1, 3, 4, 5, and 7). This includes land already within the established NCCP Reserve, the IRLR, NCCP Special Linkage, and Irvine Lake, in addition to land newly being proposed for open space designation. The open space area also includes a proposed location for a fire station along Santiago Canyon Road (Table 2-4 and Figure 2-9).

The fire station site is envisioned to provide fire and emergency medical services for the area. As part of the proposed development, an additional 6-acre commercial recreational location (Sector 10) is proposed near the intersection of Jeffrey Road and Santiago Canyon Road. This location may be used as a staging area for nearby existing and future project implemented riding and hiking trails and bikeways. In addition, approximately 12 acres (in Sectors 19 and 20, which have existing institutional uses) would be designated as institutional to reflect infrastructure use. The remaining approximately 258 acres are designated for SR-241/261 right-of-way.

Santiago Hills II and East Orange October 2004 Planned Communities Draft SEIR/EIR 2-16 J&S 03005.03

03005.03 October 2004

Figure 2-11 Conceptual Grading Plan for East Orange Planned Community Areas 2 and 3 City of Orange 2. Project Description

Two minor infrastructure facilities would also be located in the remaining areas south of Santiago Canyon Road. Adjacent to proposed Jeffrey Road would be a proposed water storage reservoir that would be constructed, owned, and operated by Santiago County Water District (SCWD). Adjacent to the proposed fire station site would be a sewer lift station.

2.4.8.1 Fire Station Site A fire station site is also anticipated for an area south of Santiago Canyon Road and the entrance to East Orange Planned Community Area 2 in Sector 4. The fire station would provide additional public fire protection for the structures and residents of East Orange Planned Community. Specifically, it is anticipated to serve Sectors 8, 9, 10, 13, 14, and 18 of East Orange Planned Community Areas 2 and 3. The existing Fire Station 7 in Santiago Hills would likely serve Sectors 11, 12, 15, 16, and 17 of East Orange Planned Community Area 1.

2.4.8.2 Commercial Recreation Sector 10 is 6 acres and located adjacent to the intersection of Santiago Canyon Road and Jeffery Road. Uses for this area would be governed by the East Orange Planned Community Development Standards, and detailed plans for specific uses would be submitted in conjunction with future map applications (Figure 2-9). In addition, approximately 12 acres (Sectors 19 and 20) would be designated as institutional for associated infrastructure to accommodate existing uses on those sites.

2.4.9 Santiago Hills II and East Orange Planned Communities Master Plan of Trails The trails master plan identifies hiking, bicycling, and pedestrian trails in the City Recreational Trails Master Plan and County Master Plan of Regional Riding and Hiking Trails. These multi-purpose trails may also be used as equestrian trails. The trails would be located off street, although in many instances the trails would be adjacent to roadway alignments. The intent of the proposed project is to amend the trails master plan to complement existing conditions, proposed development, and regional trail opportunities (Figures 2-12 and 2-13a). Accordingly, a proposed riding and hiking trail would bisect the East Orange Planned Community and link with existing and proposed trail network in Santiago Hills II Planned Community.

In Santiago Hills II Planned Community, changes are proposed to correspond to the deletion of Santiago Canyon Road. A proposed riding and hiking trail system would link the community with Peters Canyon and Irvine Regional Park. Regional trails are proposed to follow the revised street system through Santiago Hills II Planned Community north of Chapman Avenue, and provide an east/west connection to the future East Orange Planned Community and Irvine Regional Park. The Handy Creek/Jamboree Road riding and hiking trail segment would continue the existing community trail network.

In the East Orange Planned Community there would be a Class II Bikeway (on-road, striped) incorporated into Santiago Canyon Road design and constructed according to County standards. This bikeway would be owned and maintained by the County. The Circulation Element of the City General Plan describes the need to provide safe and efficient travelways for bicyclists, and the proposed Class II Bikeway would be consistent with this need.

Santiago Hills II and East Orange October 2004 Planned Communities Draft SEIR/EIR 2-17 J&S 03005.03

City of Orange 2. Project Description

In addition, the proposed plan would add an off-road regional unpaved riding and hiking trail along Santiago Canyon Road and Street “A.” The plan would revise the County Master Plan of Regional Riding and Hiking Trails. Instead of the proposed County trail connecting to Irvine Regional Park from the north via the east side of Irvine Lake and Santiago Creek, it would be rerouted to follow Santiago Canyon Road and Street “A,” then cross over SR-241/261 before connecting to the Irvine Regional Park from the south. The eastern half of the trail would be generally in the same location as the proposed County trail, however, the new trail would be south of Santiago Canyon Road instead of on the north side. (A “Haul Road Bridge Option” is also being considered for this trail, which would also require a revision to the County Master Plan of Regional Riding and Hiking Trails, as shown on Figure 2-13b. The trail would stay on the north side of Santiago Canyon Road beyond the entrance to Irvine Lake and continue on existing truck trails to the existing haul road bridge that crosses Santiago Canyon Road. The trail would continue across the bridge onto the existing truck trail south of Santiago Canyon Road, where it would connect to future proposed County trails.) The western trail segment would be located north of Street “A” and Santiago Canyon Road and would be in or adjoining the road parkway. The eastern trail segment would be located on existing truck trails on the south side of Santiago Canyon Road. In the East Orange Planned Community, trail and associated street-level crossings would be financed and constructed in conjunction with Santiago Canyon Road improvements and dedicated to the County for operation and maintenance.

The Irvine Company is requesting the following amendments to the adopted plans:

revising the County Master Plan of Regional Riding and Hiking Trails to reroute the riding and hiking trail (Santiago Creek Trail) to follow proposed Street “A” and existing Santiago Canyon Road; upgrading the existing County Class III Bikeway along Santiago Canyon Road to a Class II Bikeway; and adding an additional riding and hiking trail at the north side of Santiago Hills II Planned Community.

2.4.10 Annexation The Santiago Hills II and East Orange Planned Communities are anticipated to be annexed into the City in the future. The study area, including the Santiago Hills II and East Orange Planned Communities, is within the City’s Sphere of Influence. The City is anticipated to annex the new communities in phases to be determined by the City after having taken action on the general plan amendments and zoning changes for the Santiago Hills II and East Orange Planned Communities

The City is still determining the exact boundaries of areas to be annexed because it is anticipated that large amounts of open space associated with this proposed project area would remain in unincorporated Orange County. Annexation would proceed only after general plan and zoning amendments are approved by the City and the Local Agency Formation Commission (LAFCO) approves the boundary changes.

2.4.10.1 Sphere of Influence and the Local Agency Formation Commission One of LAFCO’s main objectives is to encourage the orderly formation of local governmental agencies. LAFCO regulates, through approval or denial, the boundary changes proposed by other public agencies or individuals. LAFCO is responsible for coordinating logical and timely changes in local governmental boundaries; conducting special studies that review ways to reorganize, simplify, and streamline governmental structure; and preparing a sphere of influence for each city and special district within each

county. The commission’s efforts are directed at ensuring that services are provided efficiently and economically while agricultural and open space lands are protected (Governor’s Office of Planning and Research 1997).

Under this authority, Orange County LAFCO governs “the initiation, conduct, and completion of changes of organization and reorganization for cities and special districts” (Government Code Section 56001). Its powers do not extend to school districts or pure financing districts (e.g., a “community facilities district” created under the Mello-Roos Community Facilities Act). In common terms, LAFCO’s responsibilities include considering proposals for creating new special districts, dissolving special districts, incorporating new cities, and annexing lands to and de-annexing lands from existing cities and special districts.

LAFCO is responsible for establishing the sphere of influence of each city and special district in the county in order to guide the efficient provision of services. The sphere of influence represents the “probable physical boundaries and service area” of that city or district (Government Code Section 56076). Annexations are limited to those lands that are within the LAFCO-approved sphere of influence. As part of its consideration of an annexation request, LAFCO would determine which of the special districts or city that would serve an area would be the best to provide services. In extending the city limits, LAFCO would also make sure that there are no redundant service providers and that services are being provided by the city or special district that is best suited to provide them.

LAFCO is in the midst of preparing its state-mandated municipal services review to identify a 20-year vision plan for services within the cities and special districts. The proposed project is one of the areas for which LAFCO is preparing a municipal service review. The municipal service review would probably not be completed before LAFCO receives the annexation proposal (Lee pers. comm.). LAFCO’s municipal service review would include a review of boundaries of the Silverado-Modjeska Parks and Recreation District and City parks, as well as water and wastewater service boundaries for IRWD and SCWD).

The Cortese-Knox Local Government Reorganization Act (Government Code Section 56000 et. seq.) provides LAFCO with its powers, procedures, and functions. This law gives LAFCO power to “approve, or disapprove with or without amendment, wholly, partially or conditionally” proposals concerning the formation of cities and special districts, and other changes in jurisdiction or organization of local governmental agencies. In reviewing proposals, LAFCO is required to consider certain factors, such as the conformity between city and county plans; current levels and need for future services to the area; and the social, physical, and economic effects that agency boundary changes present to the community (Governor’s Office of Planning and Research 1997).

2.4.11 Infrastructure for Santiago Hills II and East Orange Planned Communities Infrastructure improvements would be implemented as features of the Santiago Hills II and East Orange Planned Communities Development Plans. Infrastructure improvements are described in detail on the proposed tentative tract maps for Santiago Hills II Planned Community and East Orange Planned Community Area 1, and would similarly be described on future tentative tract maps to be prepared for East Orange Planned Community Areas 2 and 3. The proposed project would also include Southern California Edison (SCE) electrical facilities, gas facilities, telephone facilities, and cable facilities.

Santiago Hills II and East Orange October 2004 Planned Communities Draft SEIR/EIR 2-19 J&S 03005.03

City of Orange 2. Project Description

The project study area is within the service boundaries of IRWD and SCWD. IRWD is the wastewater provider for the entire project area. Santiago Hills II Planned Community and most of East Orange Planned Community Area 1 are also within IRWD’s water service boundary. A portion of the study area at the southeast end of East Orange Planned Community Area 1, and East Orange Planned Community Areas 2 and 3, are within SCWD’s water service boundary. As part of the proposed project, a subarea master plan has been prepared by IRWD for Santiago Hills II Planned Community and East Orange Planned Community Area 1. The plan defines potable water distribution and wastewater collection systems. The proposed water and wastewater infrastructure are described in more detail in Section 3M, Public Utilities.

Infrastructure items that would be constructed along with the proposed project, and are accordingly analyzed in this Draft SEIR/EIR, include:

IRWD and SCWD water storage reservoirs; storm drain and flood control facilities; urban runoff water treatment structural best management practices; roadway improvements (new roads, bridges, widening, and signalization); Baker Pipeline relocation (Santiago Aqueduct Commission facility); general infrastructure improvements/utilities (sewer system and sewer lift stations, water system and pump stations, and utilities, including electric power, gas, telephone, and cable television); fire station site improvements; on- and off-road multi-purpose and bike trails; and sports park and improvements.

2.4.12 Other Project Actions

2.4.12.1 Master Plan of Highways Amendment This Draft SEIR/EIR also analyzes several amendments to the MPAH that are associated with the proposed project area. One set of proposed MPAH amendments resulted from the recent technical study process undertaken by OCTA with the participation of the County; the Cities of Orange, Irvine, Tustin, and Anaheim; the Transportation Corridor Agencies; Caltrans; and The Irvine Company. The purpose of the technical study process was to analyze roadways that would no longer be necessary or that would no longer need to be as large due to land conservation easement dedications and reductions in development intensities in East Orange.

A second proposed MPAH amendment that is analyzed is the downgrade of Chapman Avenue from a six- lane major arterial to a four-lane primary arterial between Newport Boulevard and Cannon Road. This MPAH amendment has been identified for consideration by City staff.

The Draft SEIR/EIR analysis of the proposed project area involves comprehensive traffic studies and circulation analysis relative to the implementation of the Santiago Hills II and East Orange Planned Communities, including analysis of the City’s growth management plan and congestion management plan requirements, and site access and internal circulation within the tentative tract maps for Santiago Hills II Planned Community and East Orange Planned Community Area 1. Also, the City Master Plan of Streets and Highways is being revised as a result of changes in land use for the Santiago Hills II and East Orange Planned Communities areas, with corresponding changes to the MPAH.

deletion of the northerly extension of Jamboree Road between Santiago Canyon Road and Weir Canyon Road, deletion of the realigned Santiago Canyon Road to the east of Jamboree Road, deletion of North Lake Road between SR-241 and Santiago Canyon Road, deletion of Blue Diamond Haul Road between North Lake Road and Culver Drive, deletion of Culver Drive between Santiago Canyon Road and SR-241, deletion of Culver Loop between Santiago Canyon Road and Culver Drive, deletion of Handy Creek Road from Santiago Canyon Road to SR-261, downgrade to a collector for Handy Creek Road from Jamboree Road to SR-261, and downgrade to a primary for Santiago Canyon Road from SR-241 to Jeffery Road.

In addition, at the request of the City, the Draft SEIR/EIR analyzes a MPAH downgrading of Chapman Avenue (between Newport Boulevard and Cannon/Crawford Canyon Roads). This is analyzed in detail as two options:

1. Chapman Avenue as is it presently classified as a major arterial highway (six lanes) in the MPAH, and 2. downgrading the MPAH classification to a primary arterial highway (four lanes divided between Newport Boulevard and Cannon Road).

2.4.12.2 City-sponsored Affordable Housing Plan The City is initiating the potential for a density increase of up to approximately 46 additional housing units to accommodate affordable housing in Santiago Hills II Planned Community (Conditional Use

Permit 2488-03).C The City is utilizing density bonus provisions shown in the Housing Element and the Zoning Code (Title 17) to propose additional housing. The City Community Development Department and The Irvine Company are currently having preliminary discussions regarding Lot 340 (Sector I) of the proposed Santiago Hills II Planned Community area. The City Community Development Department is proposing to purchase or lease Lot 340 on proposed Tentative Tract Map 16201. The Irvine Company has allocated 82 units on this 3.96-acre lot. The City is proposing to increase the density by 56 percent, which would add 46 units, bringing the total number of units to 128. It is estimated that 50 percent of the units would be developed as affordable housing. The preliminary design concept of the area includes a clubhouse, a park area, and a basketball court. The impacts of both The Irvine Company’s and the City’s proposals for this lot are analyzed in this Draft SEIR/EIR.

2.4.12.3 Pre-annexation Development Agreement The proposed project includes the Pre-Annexation Development Agreement for the Santiago Hills II and East Orange Planned Communities Project (Development Agreement) between the City and The Irvine Company. A copy of the draft Development Agreement is included in Appendix A-3. The Development Agreement would

specify the terms and conditions of The Irvine Company’s consent to annexation of the property by the City,

City of Orange 2. Project Description

secure The Irvine Company’s vested rights to approvals granted by the City for the project (thus insulating the developer from future land use actions by the City that might otherwise prevent the applicant from completing the approved development), provide commitments to certain extraordinary public benefits to be provided by The Irvine Company, and specify other provisions related to the annexation and development of the project area.

The proposed Development Agreement would establish the proposed entitlement (general plan and zoning) between the City and The Irvine Company so that development rights are vested when the proposed annexation occurs. Several aspects of the Development Agreement, especially those listed as “significant public benefits” are analyzed in this Draft SEIR/EIR to the extent at which they are defined; these aspects include the following:

approximately 20 acres of community sports park facilities in East Orange Planned Community Area 1; approximately 30 acres of additional fully improved neighborhood parks (18.8 acres of which would be dedicated to the City), exclusive of the community sports park; approximately 8.0 miles of fully improved regional multi-purpose trails and approximately 7.0 miles of local multi-purpose paved and unpaved trails; conveyance or long-term lease of approximately 3.0 acres of property adjacent to Santiago Canyon Road (commonly referred to as the “Augustine Ranch”) for a staging area and/or private equestrian facilities; accelerated payment of library impact fees ($1,000,000); a fire station built and equipped by The Irvine Company on approximately 1.3 acres of property adjacent to Santiago Canyon Road; Traffic System Improvement Program (TSIP) plus a $1,076-per-unit supplemental traffic contribution to be paid at the same time as TSIP fees for improvements (but not rehabilitation or maintenance); assistance in the completion of traffic improvement projects at the Cannon Street/Santiago Canyon Road and Chapman Avenue/Prospect Street intersections; tenant improvements to the East Orange Police Substation ($50,000 contribution); designation of an approximately 3.96-acre site in Santiago Hills II Planned Community for a City-sponsored 128-unit affordable income apartment project; designation of approximately 5,170 acres for permanent open space within the City’s existing sphere of influence; all processing costs related to the annexation of the project site through LAFCO; contribution of $400,000 to pay the City’s long-term cost of providing service to the project; fair share contribution toward the costs of widening of Santiago Canyon Road to four lanes between the eastern boundary of the East Orange Planned Community Area 1 and the westerly access of East Orange Planned Community Area 2 (to be credited toward The Irvine Company’s fee obligation relative to the existing Santiago Canyon Road Fee Program or alternative fee program adopted by the City); fair share contribution toward the costs of widening Santiago Canyon Road to six lanes between the SR-261 northbound off-ramp to Chapman Avenue/Santiago Canyon Road and toward providing an SR-241 southbound on-ramp at Santiago Canyon Road (satisfied by The Irvine Company’s fee obligation relative to the existing Foothill/Eastern Transportation Corridor Agency Major Thoroughfare and Bridge Fee Program);

homeowners associations that would undertake the responsibility for the ownership and maintenance of drainage basins, bio-swales, and other water quality enhancement features not otherwise accepted by a public agency; best efforts to establish, pay the construction costs (up to $250,000), and implement a Water Enhancement Feature for Peters Canyon Reservoir, for which the applicant has proposed an aeration 2 system;TP PT and economic feasibility study for a public golf course in East Orange Planned Community Area 2 and assistance to the City in the design, development of mitigation measures, and securing of approvals for such a golf course.

2.5 Development Plan Phasing Each of the following areas is designed as a standalone operation from an earthwork/grading standpoint. Development plan phasing is estimated as follows:

Santiago Hills II Planned Community south of Chapman Avenue would be Increment 1 of the proposed project. As illustrated in Figure 2-15, infrastructure work north of Chapman Avenue would also be required to initiate this portion of the proposed project. Based on the current approval schedule, construction activity is anticipated to begin in 2005. Buildout is anticipated in approximately 2008. Santiago Hills II Planned Community north of Chapman Avenue would be Increment 2 of the proposed project and is subject to market conditions affecting Increment 1. Figure 2-16 illustrates infrastructure work related with implementation of this phase. Construction is anticipated to start in 2005, with buildout estimated in approximately 2009. East Orange Planned Community Area 1 east of SR-241 would be Increment 3 of the proposed project. This increment includes construction of a bridge over SR-241 as illustrated in Figure 2-17. Subject to market conditions affecting Increment 2, construction is anticipated to start in 2007, with buildout estimated in approximately 2010. East Orange Planned Community Area 2 would be Increment 4 of the proposed project, and is subject to market conditions affecting Increment 3. Thus, construction is anticipated to start in 2008, with buildout estimated in approximately 2010. East Orange Planned Community Area 3 would be Increment 5 of the proposed project, and is subject to market conditions affecting Increment 4. Thus, construction is anticipated to start in 2010, with buildout estimated in approximately 2010.

2 TP PT As discussed in Section 3B, Water Resources, water quality issues at Peters Canyon Reservoir are an existing condition. The project would not result in significant impacts to the water quality condition of Peters Canyon Reservoir and would not result in a considerable contribution to a significant cumulative impact.
