APPLICATION REQUEST:

SP2025-0001 (CONTINUED): Proposal of a Specific Plan for the Skyline Heights Project to establish residential and open space land uses and development standards for 249.39 acres located southwest of Foothill Parkway and north of Skyline Drive. (Applicant: Brian Hardy, Richland Ventures, Inc., 3161 Michelson Drive, Suite 425, Irvine, CA 92612) RECOMMENDED ACTION:

That the Planning and Housing Commission recommend adoption of the Addendum to the certified Skyline Heights Environmental Impact Report and approval of SP2025-0001 to the City Council, based on the findings contained in the staff report and conditions of approval.

BACKGROUND
The Skyline Heights project is a proposed master-planned residential community encompassing approximately 249.39 acres of undeveloped hillside land, located southwest of the westerly extension of Foothill Parkway and north of Skyline Heights Drive (Exhibit 1).

The project would facilitate the development of up to 276 residential units, while preserving approximately 122 acres as natural open space. The plan also includes private and public parks, a trail system, and supporting infrastructure.

The project is a revision to a previously approved residential subdivision (Tentative Tract Map 36544) from 2017. Key changes include a reduction of 16 residential units from the prior approval, the introduction of detached condominium homes as part of the project’s housing mix, the addition of 11.42 acres of park sites featuring recreational amenities, and a trail system that preserves existing trails and provides for the realignment of impacted segments to maintain connectivity from areas near Foothill Parkway to the Cleveland National Forest.

The revised project also includes a new specific plan, Skyline Heights Specific Plan, for the project site. The Specific Plan is necessary to provide development standards for the proposed condominium component of the project, which are not currently addressed in the City’s Zoning Ordinance. The Skyline Heights Specific Plan would also establish the regulatory framework for development of the project site, including new zoning designations which would replace the site’s existing R-1-7.2 zoning, development standards, a parks and trailhead plan, an infrastructure plan, construction phasing, and financing mechanisms for implementation of the plan. The applicant for the prior and current proposal is Richland Ventures.

The Skyline Heights Environmental Impact Report (EIR) was prepared and certified by the City in 2017 in connection with the prior approval. An Addendum to the EIR analyzing the proposed project revisions was prepared and is discussed in the Environmental Analysis section of this staff report.

Implementation of the revised project is tied to Tentative Tract Map (TTM) 36544, which is being resubmitted for consideration. TTM 36544 has been revised and proposes to subdivide the site into 144 residential lots and 47 lots for open space, parkland, and related infrastructure. Details regarding the resubmitted map are discussed in a separate staff report for the resubmitted TTM 36544.

The project is also associated with a development agreement, DA2018-0001, which the City approved in 2018 for the original project. The agreement gives the applicant the vested right to proceed with the development of the project for a period of 10 years and in exchange, the applicant would provide specified public benefits. The agreement extends the life of TTM 36544, and any subsequent project approvals, through November 21, 2028. Accordingly, should the City approve the resubmitted map, it would also expire November 21, 2028. The revised project does not change the terms of the agreement, which remains in effect as approved.

Additional information regarding the development agreement, the City’s denial of a previous request by the applicant to form a community facilities district (CFD) associated with the original project, and collaboration efforts between the applicant, the Community Services Department, and local trail users to address trail realignment in the Skyline area are discussed in the staff report for the resubmitted TTM 36544.

Approval of the Specific Plan is required in conjunction with the resubmitted TTM 36544 because the subdivision is designed pursuant to the zoning and development standards introduced by the Specific Plan.

The Specific Plan allows for the development of up to 276 residential units consisting of a mix of single family homes and detached condominiums on approximately 65.41 acres within the project site. Residential development is organized under two zoning designations, Single Family District (SFD) and Single Family District Cluster (SFD Cluster), which are distributed across three planning areas. The designations would replace the site’s existing R-1-7.2 zoning.

The proposed Specific Plan has undergone extensive review, and appropriate revisions have been made to ensure consistency with the requirements set forth in Chapter 17.53 of the Corona Municipal Code (CMC), which governs specific plans, as well as the General Plan.

The project site is designated Low Density Residential (LDR), which permits a density range of 3 to 6 dwelling units per acre. The project has a density of 1.1 dwelling units per acre.

CODE REQUIREMENTS
CMC Chapter 17.53 establishes the authority for the preparation and adoption of specific plans within the City’s Zoning Ordinance (Title 17) and identifies the minimum required components consistent with applicable state law governing such plans. The Skyline Heights Specific Plan satisfies all required components for a specific plan and includes additional components to promote cohesive design, orderly development, and long-term sustainability of the project.

PROPOSED SPECIFIC PLAN
The Skyline Heights Specific Plan is attached as Exhibit 3. The following sections discuss the different components of the Specific Plan, including the land use plan, construction phasing plan, infrastructure facilities, required on-site and off-site traffic improvements, vehicular circulation plan, private and public space, and community design guidelines.

Land Use Plan
Per the Specific Plan’s land use plan, the project site is divided into three planning areas and provides for a total of 276 units. Planning Area 1 (PA 1) is located on the northern portion of the site and will be developed with 104 condominium units. Planning Area 2 (PA 2) is located on the western portion of the site and will include 95 single family units, four private parks, three public parks, and supporting infrastructure facilities. Planning Area 3 (PA 3) is located on the eastern and southern portions of the site and will be developed with 77 condominium units, a private park, and supporting infrastructure facilities. All planning areas include open space in the form of manufactured slopes and undisturbed hillside areas. The land use plan is attached as Exhibit 2. Table 1 summarizes the land uses within each planning area.

Phasing
The Skyline Heights project will be constructed in two phases (Exhibit 3-14 within Exhibit 3).

Phase 1 is comprised of PA 1 located north of Mabey Canyon Road. Phase 2 is comprised of PA 2 and PA 3. The applicant intends to mass grade the entire project site under Phase 1.

With the exception of the Zone 5 water tank, the project’s associated infrastructure, including the water quality basins, pump stations, and streets, will be developed concurrently with their corresponding phases. The Zone 5 water tank, which is located in the Phase 2 area, is required to be constructed prior to the issuance of the first building permit in either phase.

Residential Designations
SFD Designation. The SFD designation is situated in PA 2 and allows for 95 single family residential lots. The Specific Plan prescribes the standards for minimum lot size, required lot width and depth, building setbacks, maximum lot coverage, building height limits, and minimum parking requirements per dwelling unit for the single family residential lots. These development standards are compatible with other single family residential zones in the City, including the site’s existing R-1-7.2 zone.

SFD Cluster Designation. The SFD Cluster designation is situated in PA 1 and PA 3 and allows for up to 181 detached condominium homes combined. The Specific Plan prescribes the standards for the minimum lot size, required lot width and depth, minimum building setbacks and building separation, building height limits, maximum lot coverage, and minimum parking requirements per dwelling unit.

The condominium lots proposed by TTM 36544 are sized to accommodate a cluster of four to eight units, each with individual garages accessed via a shared private alley that connects to internal streets within the development. Because this designation is for condominium development, the development standards include a minimum exclusive use area of 2,700 square feet per unit in PA 1 and 3,300 square feet per unit in PA 3. The exclusive use area is comprised of the area underneath the building footprint and the front, side and rear yards that are fenced for the private, exclusive use of each condominium unit.

Open Space Designation
Land designated as Open Space within the Specific Plan includes natural open space, manufactured slopes, fuel modification zones, trails, utility facilities, and private and public parks. There is approximately a total of 184 acres of open space within the specific plan, which includes approximately 122 acres of natural open space that will remain undisturbed.

Permitted uses in the Open Space designation include trails, fuel modification zones, utility facilities such as water tanks and booster stations, telecommunications facilities, and parks. Exhibit 3-2 within Exhibit 3 identifies the areas designated for open space and parks within the project.

Parks and Trails
The Skyline Heights project will provide five private parks totaling 2.17 acres for the exclusive use of the residents within the tract. In addition, the project includes three public parks, including a dog park, totaling 9.25 acres. The conceptual plans include on-site parking, playgrounds, basketball and pickleball courts, a bike track, and other recreational amenities. The final design and specific improvements will be determined by the Community Services Department and formalized through a Parks Development Agreement between the applicant and the City. A conceptual landscape and park plan is shown in Exhibits 3-2, 3-3 and 3-4 within Exhibit 3.

Existing trails identified in the City’s Trails Master Plan that will be affected by the project are proposed to be realigned within the project boundaries to maintain trail connectivity from areas near Foothill Parkway through the project site and into the Cleveland National Forest.

The project includes four trailheads which will be constructed at different points of the relocated trails: one is located at the project entrance at “B” Street and Foothill Parkway; two are centrally situated near the public parks; and the fourth is located in the southern portion of the Phase 2. The trail plan and trailhead improvements are conceptually shown on Exhibits 3-7, 3-8 and 3-9 within Exhibit 3.

Additionally, at the time of the recordation of TTM 36544, the applicant is required to offer 10 lots totaling 84.65 acres within the subdivision to the City in fee title. These lots include areas designated for natural open space, public parks, trails, water tanks, and booster stations.

Water and Sewer Facilities
Water and sewer services for the project will be served by the City. The project will construct water and sewer lines sized to meet City standards which will connect to existing lines in Foothill Parkway and extend through the project as needed. The residential lots will be provided with potable water, while the common landscaped areas, manufactured slopes, and parkways will be irrigated with reclaimed water. The water, reclaimed water, and sewer plan are illustrated in Exhibits 3-10, 3-11, and 3-12, respectively, within Exhibit 3.

The applicant is required to construct a 0.6-million-gallon Zone 6A water tank to serve the project. The full construction cost of this facility is the responsibility of the applicant. The northern portion of the development may be served by the City’s existing Zone 5 water system; however, the City’s Utilities Department has identified the need for an additional

2.5-million-gallon Zone 5 water storage tank to adequately serve this area. Because the proposed Zone 5 water tank will provide capacity not only for a portion of the project site but also for other existing and future neighborhoods in that area, the applicant is required to pay a fair share cost towards the construction of the Zone 5 water tank. The locations for the water tanks are identified on Exhibit 3-1 within Exhibit 3.

Circulation Plan
Vehicular access into the project site is provided at three locations on Foothill Parkway. The northern access point is located just north of Mabey Canyon Road at “P” Street. The central access point is provided by “B” Street, which will form a four-way intersection at Foothill Parkway and Border Avenue. The southern access point is at Trudy Way which currently provides access to the Orchard Glen neighborhood (Tract 31955) located south of the project site. Trudy Way is currently a cul-de-sac, but will be extended to connect to “E” Street within the project.

All streets within the project are designed per city standard and include two-way travel lanes, curb and gutter, sidewalk and landscaped parkway. The primary streets (“A”, “B”, and “E” Streets), which provide access to secondary streets and cul-de-sacs within Phase 2, will include striping for either a Class 2 or Class 3 bike lane. Streets within Phase 1 are proposed to be private, with the exception of the entry road into Phase 1 (“P” Street) which will be public. The streets within Phase 2 will be public to serve the proposed public parks within Phase 2. The circulation plan for the project is shown on Exhibit 3-5 within Exhibit 3.

A traffic impact analysis was prepared for the project by Urban Crossroads (January 23, 2025). The project is forecast to generate a total of 2,604 vehicle trips per day, 176 trips less than the original approved project. The applicant is required to make the recommended traffic improvements identified in the traffic study, which are discussed in the staff report for TTM 36544.

Community Design Guidelines
The Specific Plan proposes community design guidelines to ensure that development occurring within the project site are aesthetically cohesive, visually appealing, and well designed with a Tuscan-Italianate character. Permitted materials for walls, mailbox structures, community signage, and residential buildings include rustic stone veneer, sandfinish stucco, terra cotta clay tiles, heavy timber beams, dark stained wood, decorative pottery, “used” brick, and decorative ceramic tile. Standards for architecture, fencing, landscaping, and fuel modification are described below.

Architecture. Seven architectural styles are proposed for the project: Spanish Eclectic, Transitional Craftsman, Tuscan Farmhouse, Italian Revival, European Cottage, Modern American Farmhouse, and Midwest Traditional. Additional styles may be approved through the precise plan review process. The design guidelines include required and suggested architectural elements for building formation, roof pitch and design, exterior wall finishes, window treatments, architectural detailing, and color palettes.

Landscaping. The guidelines address landscaping for community entry monument signs, parkways and street medians, manufactured slopes, and parks. The landscaping is intended to enhance entry points, promote visual continuity throughoutthe community, and support water conservation through the use of water-efficient landscaping. A master plant palette is provided, consisting of drought tolerant plant species, along with a separate fuel modification plant palette approved by the Fire Department for use within designated fuel modification zones.

Fencing. Decorative block walls are required for the perimeters of the single family residential lots. Lots with views may use alternative materials such as wrought iron, glass, or plexi-glass materials. Condominium lots must also have decorative block perimeter walls, but vinyl fencing is allowed between the units to separate their exclusive use areas (side and rear yards) for privacy. The Specific Plan prescribes a maximum height of six feet for wall and fences. The proposed materials and height limit for fences and walls are consistent with residential developments built throughout the City.

Fuel Modification. The entire project site is located in a Very High Fire Severity Zone. As such, fire protection planning is necessary to ensure a fire-safe environment for future residents within the tract. The Specific Plan identifies five fuel modification zones throughout the project site, with each zone prescribing varying defensible space requirements, such as the installation of noncombustible construction and materials, fireresilient landscaping, and thinning of dead/dying landscaping. The fuel modification plan has been reviewed extensively by the Fire Department. A final plan will be required to be submitted for review and approval at the time of project development.

Community Facilities District
The applicant is required to form a CFD or annex the entire project into CFD 2016-3 for the purpose of funding the maintenance of public facilities associated with the project. Such facilities include, but are not limited to, public streets, curb and gutter, streetlights, storm drains, sidewalks, trails, traffic signals, parks, pavement, and public landscaping within CFD easements.

The applicant is also required to annex the entire project into CFD 2016-1 for the purpose of funding public services associated with the project, including, but not limited to, police and fire emergency services.

Following approval of the project entitlements, the applicant intends to submit a separate application to the City for the formation of a CFD to finance the construction of the three public parks and associated improvements, including play structures, pickleball courts, basketball courts, picnic shelters, fitness equipment, bike pump track, bike park, bench seating areas, bike racks, restroom, drinking fountains, a major trailhead, and an on-site parking lot. The formation of the CFD is subject to the approval of the City Council. Per the project conditions of approval for TTM 36544, if the City approves the CFD, the applicant shall construct the public parks and associated amenities prior to the issuance of the 221st building permit. However, if the City does not approve formation of the CFD, the applicant would not be obligated to construct the public parks and associated improvements. In other words, the three public parks and one of the major trailheads proposed within one of the public parks will only be constructed as part of project if the City agrees to form the CFD. In any event, though, the applicant would still be required to offer the lots designated for public parks to the City for future construction by the City.

ENVIRONMENTAL ANALYSIS
The City approved the original project and certified the Skyline Heights Final EIR on February 1, 2017 (State Clearing House No. 2014021003). An Addendum to the certified EIR has been prepared for the revised project in accordance with Section 15164 of the State CEQA Guidelines and Section 8.06 of the City’s Local CEQA Guidelines. The Addendum is supported by substantial evidence demonstrating that, in light of the whole record before the City, none of the conditions described in CEQA Guidelines Sections 15162 or 15163 requiring preparation of a subsequent or supplemental EIR have occurred. Implementation of the revised project would not result in new or substantially more severe environmental impacts previously identified in the certified EIR. Pursuant to Section 15164, an Addendum is not required to be recirculated for public review, but may be considered by the decisionmaking body in conjunction with the previously certified EIR. The Addendum, Draft EIR, and Final certified EIR are attached as Exhibits 5, 6, and 7, respectively.

The certified EIR evaluated the project’s potential environmental impacts in the areas of aesthetics, agriculture and forestry resources, air quality, biological resources, cultural resources, energy, geological and soils, greenhouse gas emissions, hazards and hazardous materials, hydrology and water quality, land use and planning, noise, population and housing, public services, transportation, and utilities and services systems. With the exception of impacts related to aesthetics, all identified impacts were determined to be less than significant with implementation of mitigation measures. The EIR concluded that impacts to visual character, scenic vistas, and visual resources resulting from substantial landform alteration would be significant and unavoidable, and that no mitigation measures are available to reduce the significance of these impacts.

The Addendum evaluated the revised project across the same environmental issue areas in the certified EIR, and also includes analysis of additional topics (energy, tribal cultural resources, and wildfire) consistent with current CEQA requirements. The analysis concluded that the revised project would not result in any new or substantially more severe environmental impacts previously identified in the certified EIR. All impacts, with the exception of those related to the area of aesthetics, would be reduced to less-thansignificant levels through the implementation of mitigation measures. Impacts to aesthetics, however, would remain significant and unavoidable, consistent with the conclusions of the original EIR.

The Addendum also identified additional biological mitigation measures, which have been incorporated into the revised project to further reduce potential impacts to biological resources.

FISCAL IMPACT
The applicant has paid the applicable application processing fees for the specific plan application.

PUBLIC NOTICE AND COMMENTS
A 10-day public notice was mailed to all property owners within a 500-foot radius of the project site, as well as advertised in the Sentinel Weekly News and posted at the project site.

As of the preparation of this report, the Planning and Development Department received one call from a resident inquiring whether the project homes will be visible from her residence on Condor Circle, and a letter of opposition from a resident. The letter is attached as Exhibit

8. STAFF ANALYSIS:

The goals of the Skyline Heights Specific Plan are to: (a) establish a comprehensive land use plan that identifies land uses, roadways and public facilities; (b) promote high quality residential development through community design guidelines, c) provide open space that integrates natural and improved areas to support scenic character and fire-safe living conditions for future project residents, and (d) implement a circulation system that ensures safe internal mobility while minimizing impacts to existing residential neighborhoods.

The Skyline Heights Specific Plan achieves these goals by establishing development standards for three residential planning areas, incorporating community design guidelines for architecture, landscaping, fencing, and fuel modification, and providing a coordinated circulation and infrastructure phasing plan involving the installation and construction of water and sewer facilities and off-site traffic signals. The Specific Plan also provides for the development of five private parks and three public parks depending upon whether the City agrees to approve the CFD for the construction of the public parks. The buildout density of the Specific Plan is 1.1 dwelling units per acre, which is substantially below the General Plan maximum density of six dwelling units per acre for the Low Density Residential designation.

The Specific Plan takes into consideration the project site’s location within the Very High Fire Severity Zone. The Specific Plan includes a fuel modification plan, secondary emergency access points, adequate water reservoir storage, a heli-hydrant to support aerial firefighting, an infrastructure plan that meets Fire Department requirements for fire protection, and residential design standards that require compliance with the applicable California Building Code materials and construction standards for exterior wildlife exposure.

Therefore, the Skyline Heights Specific Plan establishes a comprehensive planning framework for residential development consistent with the General Plan. Based on the following findings and the recommended conditions of approval in Exhibit 4, SP2025-0001 is recommended for approval.

FINDINGS OF APPROVAL FOR SP2025-0001:

1. In accordance with Section 15164 of the State CEQA Guidelines and Section 8.06 of the City’s Local CEQA Guidelines, the City of Corona, as the lead agency under CEQA, has prepared an Addendum to Skyline Heights Final EIR, which was certified by the City on February 1, 2017 (State Clearing House No. 2014021003). The Addendum is supported by substantial evidence demonstrating that, in light of the whole record before the City, none of the conditions described in CEQA Guidelines Sections 15162 or 15163 requiring preparation of a subsequent or supplemental EIR have occurred. Implementation of the revised project would not result in new or substantially more severe environmental impacts previously identified in the certified EIR. The Addendum concluded that all impacts, with the exception of those related to the area of aesthetics, would be reduced to less-than-significant levels through the implementation of mitigation measures.

Impacts to aesthetics, however, would remain significant and unavoidable, consistent with the conclusions of the original EIR.

2. The Plan systematically implements and is consistent with the General Plan for the following reasons:
a. The Skyline Heights Specific Plan establishes a master-planned residential community that is consistent with the General Plan land use designation of Low Density Residential, which permits a density range of 3 to 6 dwelling units per acre. The proposed project has an overall density of 1.1 dwelling units per acre, which is below the maximum allowable density of 6 dwelling units per acre established by the Low Density Residential designation, and is therefore, consistent with the General Plan.
b. General Plan goal LU-1 is to provide for a community that contains a diversity of land uses that support the needs of and provides a high quality of life for its residents, sustains and enhances the city’s economy and fiscal balance, is supported by adequate community infrastructure and services, and is compatible with the environmental setting and resources. The Skyline Heights Specific Plan is consistent with this goal because it provides for 276 single family homes, park and trail facilities, and infrastructure improvements such as roadways, and water and sewer facilities, necessary to sufficiently serve the project and not adversely impact the City’s fiscal condition. The project also preserves approximately 122 acres of natural open space. c. General Plan Goal CD-4 is to provide for a network of trails and greenways that interconnect Corona’s parklands, open spaces, and drainages that provide hiking and bicycle opportunities and access into surrounding open spaces and natural areas. Consistent with this goal, the Skyline Heights Specific Plan provides for lots that are designated for natural open space, private and public parks, multi-use trails, and Class 2 and 3 bike lanes. These trails will complement the on-site open space and provide access to existing surrounding trails.
d. General Plan Goal CE-1 is to provide a roadway network of complete streets that provide accessibility for all users of all ages and abilities while maintaining context sensitivity to the land uses identified in the Land Use Element. The Skyline Heights Specific Plan includes a roadway network plan that provides accessibility for pedestrians, vehicles, and emergency personnel. The project’s circulation system has been planned to support safe and efficient movement throughout the development, is consistent with the intended residential land uses it serves, and is designed in accordance with applicable City standards.
e. General Plan Goal PR-1 aims to provide a well-design system of parks and associated facilities that are sufficient in acreage, type, and distribution, that are designed to provide a quality of recreational experience, and that meet the diverse needs of Corona’s residents. The Skyline Heights Specific Plan is consistent with this goal, as it provides for approximately 11.42 acres of combined private and public parkland featuring recreational amenities that support active and passive uses. The proposed park sites are integrated throughout the project site to enhance accessibility and usability and is designed to serve the recreational needs of both existing and future residents of the City.
f. General Plan Goal PS-10 seeks to reduce fire risk to life and property through effective land use planning and compliance with federal, state, and local laws, ordinances, and standards. The project is consistent with this goal, as it incorporates fire protection measures to minimize wildfire risk and enhance emergency response capabilities. These measures include the implementation of a Fire Protection Plan approved by the City of Corona Fire Department, construction of two water reservoirs to support fire suppression needs, fuel modification within identified defensible space zones, secondary emergency access points, and the installation of a Fire Department-required heli-hydrant to improve aerial firefighting operations and response efficiency.

3. The Plan provides for the development of a comprehensively planned project that is superior to development otherwise allowed under the conventional zoning classifications for the following reasons:
a. The Skyline Heights Specific Plan establishes a coordinated master-planned development framework that integrates land use, circulation, infrastructure, open space, and design standards in a manner that would not be achieved through convenient zoning alone. Unlike conventional zoning regulations, which apply uniform development standards on a parcel-by-parcel basis, the Specific Plan allows for site-specific planning that responds to the project’s hillside topography, environmental resources, and surrounding land uses. b. The Skyline Heights Specific Plan incorporates infrastructure planning, phasing, and financing mechanisms that ensure the orderly and timely provision of public facilities and services. This comprehensive approach provides improved design outcomes, orderly development, and enhanced community amenities, resulting in a planned project that is superior to development otherwise allowed under conventional zoning regulations. c. The project is required to contribute a fair share cost towards the construction of a new 2.5-million-gallon Zone 5 water storage tank which will serve not only a portion of the development but also existing and future developments in the Zone 5 service area.

4. The Plan provides for the construction, improvement, or extension of transportation facilities, public utilities and public services required by the long-term needs of the project and/or other area residents, and complements the orderly development of the City beyond the project's boundaries for the following reasons:
a. The Skyline Heights Specific Plan includes a comprehensive infrastructure program that provides for the construction and improvement of roadways, water, sewer, drainage, and public service facilities required for the long-term needs of the project and/or other area residents in the vicinity. The proposed circulation system establishes internal roadway improvements and connections to the surrounding roadway network, ensuring adequate access for residents and emergency services. The project includes the construction of a 0.6-million-gallon Zone 6A water storage tank to serve the project. In addition, the project will contribute a fair share cost towards the construction of a new 2.5-million-gallon Zone 5 water storage tank, which is necessary to serve the project and existing and future development within the Zone 5 service area. Furthermore, the project incorporates fire protection infrastructure, including a heli-hydrant to support emergency response capabilities within the project area, and 11.42 acres of combined park sites with recreational amenities. As such, the Specific Plan supports the orderly development of the City beyond the project’s boundaries.

5. The Plan provides for the appropriate orientation and relationship between land use within and adjacent to the project for the following reasons:
a. The Skyline Heights Specific Plan establishes a land use plan that organizes residential development, open space, and recreational amenities in a manner that is compatible with the site’s hillside environment. The residential lots are arranged in a clustered pattern that responds to the site’s natural topography, thereby minimizing visual and physical impacts on adjacent properties. The larger park sites are centrally located within the project, away from residential lots to minimize potential land use conflicts, while smaller neighborhood parks are integrated and distributed throughout the community to enhance accessibility and usability. The design allows for greater preservation of natural open space while maintaining appropriate buffering between the development and surrounding land uses.
b. Natural open space and existing hillside terrain will be preserved between the developed areas within the project and Foothill Parkway, creating a physical and natural buffer that separates the project and existing neighborhoods located on the opposite side of Foothill Parkway. This helps maintain the natural character of the area, reduces potential land use conflicts, and ensures a compatible transition between the proposed development and surrounding communities.

6. Pursuant to California Government Code Section 66300 (Housing Crisis Act of 2019), the adoption of the Skyline Heights Specific Plan (SP2025-0001) would not individually or cumulatively reduce the site’s residential development capacity for the following reason:
a. The Housing Crisis Act of 2019 (Government Code Section 66300; enacted by Senate Bill 330) prevents a city from changing the general plan land use designation, specific plan land use designation, or zoning of a parcel to a less intensive use below what was in effect on January 1, 2018, unless the city concurrently changes the regulations applicable to other parcels within the jurisdiction to ensure that there is no net loss in residential capacity. (Subds. (b)(1)(A), (h)(1).) However, Section 66300(e)(4) provides that the Housing Crisis Act does not apply to a housing development project located within a very high fire hazard severity zone. Because the proposed Project involves a housing development project on a site that is located entirely within a Very High Fire Hazard Severity Zone, the Housing Crisis Act does not apply to SP2025-0001 and associated TTM 36544.

SECTION 1 - INTRODUCTION
The Skyline Heights Specific Plan No. 2025-0001 creates a 249.39-acre master-planned community that establishes a total of 276 homes on 65.41 acres, park space spanning over nine (9) acres in size, while also preserving approximately 127.9 acres of undisturbed open space. Skyline Heights is designed to provide a variety of housing opportunities in three (3) distinct neighborhoods, while also providing active and passive recreational space for residents of Skyline Heights and surrounding communities. The overall design and layout of the Skyline Heights Specific Plan creates a strong sense of place and integrates the hillside character of the project site with the established surrounding communities as well as the greater Corona area.

The Skyline Heights Specific Plan provides the City of Corona with a set of regulations and guidelines to help create a high-quality planned residential community, ensuring the orderly development of the Project site and systematic implementation of the City’s General Plan.

1.1 PROJECT LOCATION
Skyline Heights is located in the City of Corona, south of the 91 Freeway, between Highway 241 and Interstate

15. See Exhibit 1-1, Regional Location. Access to the Skyline Heights community is provided via Foothill Parkway.

The Skyline Heights Specific Plan area is located west of Foothill Parkway and north of Skyline Drive, in southwest Corona. See Exhibit 1-2, Vicinity Map.

The Skyline Heights Specific Plan is comprised of the following 10 Assessor Parcel Numbers: 275-030-010; 275-040-006, -011, -012, -023, -024; 275-050-020, -021; 275-070-003; and 275-080-010.

1.2 PROJECT OVERVIEW
The Skyline Heights Specific Plan establishes three (3) single-family residential neighborhoods nestled within the lower hillside ridgelines. Approximately 121.9 acres (48.9%) of the project site will remain open space and provide residents with a natural hillside backdrop, which reinforces the hillside character of the community. Foothill Parkway and natural open space provides a buffer from existing residents to the northeast and southeast.

With approximately 11.42 acres of park space provided, Skyline Heights offers recreational amenities that include active and passive use activities. The southern portion of the park is designed to include an open field park and one (1) dog park. The central portion of the park area features a pump track, bike track, tot lots, as well as basketball and pickleball courts. The northern portion features a kite park and meandering park space that includes walking trails. The developed areas of the park space features a cohesive landscape concept that enhances the Skyline Heights Specific Plan’s architectural theme and is harmonious with the hillside development character of the established surrounding communities.

A comprehensive vehicular circulation system is provided to facilitate access within the community. Primary access into the Skyline Heights community is provided from Foothill Parkway at two locations currently identified as “B” and “P” Streets. A third access is provided via “M” Street which connects to Trudy Way, an existing local street located in the southeast segment of the project site that ultimately connects with Foothill Parkway.

Access to Foothill Road for the adjacent residents will be provided through PA 1 via a 28’ wide private drive located at the end of “P” Street.

An Emergency Vehicle Access Road (EVA) is provided at the end of “P” Street from Mabey Canyon Drive for emergency vehicle access and emergency ingress/egress.

1.3 AUTHORITY AND SCOPE
California Government Code §65450 through §65454 establish the authority to adopt Specific Plans, identify the required content of a Specific Plan, and mandate consistency with the applicable General Plan. References to the location of this information within the Skyline Heights Specific Plan are shown in bold. According to § 65450, a Specific Plan is required to include text and a diagram or diagrams which specify all of the following details:
1) The distribution, location, and extent of the uses of land, including open space, within the area covered by the plan. (Section 3)
2) The proposed distribution, location, and extent and intensity of major components of public and private transportation, sewage, water, drainage, solid waste disposal, energy, and other essential facilities proposed to be located within the area covered by the plan and needed to support the land uses described in the plan. (Section 3)
3) Standards and criteria by which development will proceed, and standards for the conservation, development, and utilization of natural resources, where applicable. (Section 4) 4) A program of implementation measures including regulations, programs, public works projects, and financing measures necessary to carry out the items listed above. (Section 6) 5) A statement of the Specific Plan’s relationship to the General Plan. (Section 7) California state law also provides for the inclusion of any other subject that, in the judgement of the local planning agency, is deemed necessary or desirable to implement the General Plan, such as architectural or landscape design guidelines.

The Skyline Heights Specific Plan No. 2025-0001 includes all of the required elements listed above, as well as architectural and landscape guidelines. This Specific Plan also provides an essential link to the applicable policies of the City of Corona General Plan. All implementing development plans are required to substantially conform to the standards and guidelines set forth in this document, as well as all other applicable City regulations. The regulations of the Corona Municipal Code shall apply where the Specific Plan remains silent (Municipal Code Section 17.53.010).

1.4 PURPOSE OF THE SPECIFIC PLAN
Authorized by the California Government Code § 65450 et seq., a Specific Plan is a planning tool that is used for the systematic implementation of the General Plan for all or part of the area covered by the General Plan. It effectively establishes a link between implementing policies of the General Plan and the individual development proposals in a defined area. As such, this Specific Plan document provides the City of Corona a mechanism to ensure the efficient and orderly development of the Skyline Heights area that is consistent with the City’s General Plan.

All future implementing actions (development plans, tract maps, plot plans, conditional use permits, site plans, and other entitlements) for property located within the boundaries of this Specific Plan are required to be consistent with the standards set forth in this document and with all other applicable City of Corona regulations, as discussed in Section 6, Implementation and Administration. This Specific Plan provides text and exhibits that describe the various land uses, amenities, and infrastructure improvements envisioned to occur in the Specific Plan area.

1.5 RELATIONSHIP OF THE SPECIFIC PLAN TO THE GENERAL PLAN Pursuant to California Government Code Section 65454, a Specific Plan shall be consistent with the local jurisdiction’s General Plan. The Skyline Heights Specific Plan provides regulations, guidelines and standards that are consistent with and implement the goals and policies of the City of Corona General Plan. Consistency with the City’s General Plan is demonstrated in Section 7. Skyline Heights components, which are found to be consistent with the Specific Plan, shall be deemed consistent with the General Plan.

1.6 CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA) COMPLIANCE Pursuant to the California Environmental Quality Act (CEQA), a Project Environmental Impact Report (EIR) was prepared and certified in 2017 for the implementation of the Skyline Heights Project. The EIR (SCH No. 2014021003) identifies potential environmental effects of Skyline Heights Project’s implementation and sets forth mitigation measures to reduce those impacts as feasible. The evaluation of environmental impacts under CEQA for the Skyline Heights Specific Plan area is contained in the project’s Addendum to the EIR (SCH No. 2014021003) prepared for and certified by the City of Corona concurrently with the approval of the Skyline Heights Specific Plan No. 2025-0001.

The City of Corona is a lead agency under CEQA; the City of Corona has the authority to certify the Skyline Heights Specific Plan EIR Addendum, prior to approving the Specific Plan. Public Resources Code, Section 21081.6 also requires public agencies to adopt a mitigation monitoring and reporting program (MMRP) to ensure that any applicable mitigation measures are implemented. The City is required to confirm that any applicable mitigation measures have been implemented in accordance with the adopted MMRP. The City of Corona City Council originally certified the Skyline Heights Project Final EIR and adopted the associated MMRP in January 2017.

1.7 SEVERABILITY
This Specific Plan document enables the City of Corona to facilitate the processing and approval of implementing permits and approvals necessary for development in the Skyline Heights Specific Plan. If any regulation, condition, program, clause, phrase, or portion of this Specific Plan is held invalid or unenforceable, such portions shall be deemed separate, distinct, and independent provisions, and the invalidity of such portions or provisions shall not affect the validity and enforceability of the remaining provisions contained in this Specific Plan.

1.8 EFFECT ON CONFLICTING CONDITIONS
Whenever the provisions of this Specific Plan permit greater flexibility than, or establish regulations different than those imposed or required by the Corona Municipal Code, the provisions of this Specific Plan shall prevail.

SECTION 2 - EXISTING CONDITIONS
At the time this Specific Plan was prepared (2025), the Skyline Heights Project site (“Project site”) was undeveloped.

The property consists of approximately 249.39 acres within the City of Corona. The balance of the property is relatively undisturbed hillside, marked only dirt roadways and trails, grading and terrace drains related to the adjacent Foothill Parkway project, and the occasional evidence of past grading or dumping activities.

2.1 PROJECT HISTORY
Prior to the approval of this Specific Plan, the Project Site had a General Plan land use designation of Low Density Residential (LDR) and a zoning of R-1-7.2. See Exhibit 2-1, Existing General Plan and Zoning. Tentative Tract Map 36544 (TTM 36544) was also previously approved on February 1, 2017 for the Project Site to create 292 single family lots on 65.41 acres. The R-1-7.2 zoning required each lot to have a minimum lot area of 7,200 square feet and the approved density was one dwelling unit per acre.

This Skyline Heights Specific Plan (2024) replaces the existing R-1-7.2 zoning with new zoning of Single-Family Detached (SFD) and SFD Cluster, which corresponds with the R-1-7.2 zoning, but provides more flexible development standards. The Specific Plan’s SFD zoning allows for the development of traditional single-family detached homes on individual lots, while the SFD Cluster zoning allows for single-family detached cluster units on condominium lots. The SFD and SDF Cluster zoning maintain the same minimum lot size requirement of 7,200 square feet under the R-1-7.2 zoning.

This Specific Plan also proposes 276 units, 16 units less than the 292 units that were originally approved for TTM 36544 in 2017.

A General Plan Amendment was not required with the approval of this Specific Plan, because the Specific Plan proposes less units than what was originally approved for the site under TTM 36544. Additionally, the Specific Plan’s SFD and SFD Cluster zoning standards are consistent with the City of Corona’s General Plan Low Density Residential designation.

A resubmitted Tentative Tract Map 36544 was approved on (DATE TBD) in conjunction with the approval of this Specific Plan to reflect the lot configuration that is depicted on Exhibit 3-1, Land Use Plan and to include lots for the development of parks.

2.2 SURROUNDING LAND USES
The Project site is surrounded by natural open space, vacant land, and residential uses. Directly west and southwest of the Project Site are the upper foothills of the Santa Ana Mountains and the Cleveland National Forest located within unincorporated Riverside County. A residential portion of the Sierra Bella Specific Plan is located further north of Mabey Canyon Road and Foothill Parkway.

Existing residential homes within the Crown Properties Specific Plan and uses designated Low Density Residential and Open Space General are located across Foothill Parkway, to the northeast.

The southern portion of the Project site abuts undeveloped land and existing residential homes designated Estate Residential, Low Density Residential, Medium Density Residential, General Commercial, and Open Space General. 2-2
EXHIBIT 2-1 EXISTING GENERAL PLAN AND ZONING

2.3 TOPOGRAPHY
The Project site is located in the northern foothills of the Santa Ana Mountain Range and a portion of the Project site is located at the mouth of Mabey Canyon and near the Tin Mine and Kroonen Canyons.

The Project site is characterized by moderate to steep topography with slopes namely covered in dense chaparral and scrub oak. The onsite elevations generally increase from the northeast to the southwest and range from 945 feet to approximately 1,730 feet above mean sea level (AMSL).

Several northwest to southeast trending “spine” ridges radiate from a main ridge at the upper elevations in the southwest corner of the property. The ridges are separated by steep sided V-shaped canyons, which generally drain from the east to west.

2.4 SOILS/GEOLOGY
The Project site is bisected by the Elsinore Fault, which bounds the northeast side of the Santa Ana Mountains.

The Chino Fault, which primarily bounds the Chino Hills area, lies northwest of the property. On-site Pleostocene terrace deposits are located on the flattened ridge tops. Design considerations for any rupture and other secondary seismic hazards will be considered as part of the final engineering plans approval, as necessary.

On-site soils can be characterized as variations of sandstone, pebble and cobble conglomerates, claystone, and granitoid boulders. The potential for subsidence or liquefaction within the property is low. Preliminary testing indicates that the on-site soils would have very low-to-medium expansion potential. Additionally, no large-scale mining operations have been identified on-site.

2.5 HYDROLOGY AND DRAINAGE
The Project site is located within the Santa Ana River Watershed and Region 8 (Santa Ana Region) of the California Regional Water Quality Control Board (RWQCB). There are several canyons and ravines that convey natural drainage to the property, which generally drains from west to east. Much of the property is tributary to the east through three (3) canyons, which discharge into Mabey Canyon. The Mabey Canyon drainage flows into a large flood control basin located at the canyon’s mouth, and conveys flows to Temescal Canyon, which ultimately flows into the Santa Ana River system.

The City of Corona Drainage Master Plan does not identify the drainage facilities for the area surrounding the Skyline Heights Specific Plan area.
2-4

2.6 VIEWS AND AESTHETICS

2.6.1 Views Off-site
Off-site natural landforms, such as surrounding hills, mountains, and drainage ways, provide major visual elements for the property. Prominent features in the surrounding area include the Santa Ana Mountains and Cleveland National Forest to the south and west, which form a backdrop for the property. The Sierra Peak mountains provide the primary backdrop for the property to the west, and has a peak elevation of 3,000 feet, which is approximately 1,300 feet above the highest elevation on Skyline Heights. Further west, the Santa Ana Mountain range forms a skyline silhouette for the property.

2.6.2 Views onto the Site
The Project site is most visible from Foothill Parkway, located east of the property. Residents east of the Project site have views of the existing property, however, natural open space and on-site public parks provide visual relief and minimize direct line of sight.

2.7 BIOLOGY
The Project site contains disturbed and undisturbed native habitat and non-native species, including vegetation communities primarily consisting of chaparral and coastal sage scrub. Approximately 10 acres of the property have been identified as riparian/riverine areas, and both riparian and woodland habitats have been identified onsite.

No wetlands have been identified within the Project site. The Skyline Height Project has been designed to be consistent with the Riverside County Multiple Species Habitat Conservation Plan (MSHCP).

A portion of the southeast property has been disturbed by human activity and existing dirt roads.

Development Plan HEIGHTS

SECTION 3 - DEVELOPMENT PLAN

3.1 SPECIFIC PLAN GOALS
The intent of the Skyline Heights project is to provide a planned single-family residential community with a variety of housing sizes and types, including single-family homes and detached condominium homes. Private open space areas and a public park surrounded by natural open space with multiple bike and multi-use trails provide a variety of lifestyle choices for residents. The overall goals of the Skyline Heights Specific Plan are as follows:
1) Establish a comprehensive land use plan that designates the location, size and intensity of all land uses, roadways, public open space and public facilities within the Specific Plan area. 2) Prepare a Specific Plan that implements the policies of the City of Corona General Plan, provides the standards and guidelines to allow for flexibility to accommodate exemplary planning and design and is comprehensive, understandable and easy to use.
3) Provide access for the efficient and safe movement of vehicles and pedestrians with minimum intrusion on residential neighborhoods.
4) Ensure high quality residential development through the use of community design guidelines that are consistent with the goals and objectives of the General Plan. 5) Establish minimum lot sizes and architectural guidelines for a high quality aesthetic residential community, unique in community design and aesthetic character.
6) Design and dedicate a public park with active and passive recreational opportunities, as well as hiking and bicycling trails for the City’s residents.
7) Plan a system of open space which combines natural and man-made areas to maintain a scenic and fire -safe living environment for residents.
8) Ensure that fire regulations, safe access and other fire safety measures including fuel modification zones are implemented to address the project’s high fire hazard location. 9) Ensure the timely completion of all community facilities including circulation improvements, drainage facilities, and domestic water and sewer improvements that will serve the project, benefit the adjacent neighborhood and implement the City’s master plan for infrastructure.

The intent of the Specific Plan goals are to establish zoning and planning policies, standards, and guidelines for the development of Skyline Heights to create a planned community, which will be in harmony with the natural environment, will preserve sensitive and prominent open space within the site, provide public park areas with a variety of recreational opportunities and implement improvements to provide public facilities and public streets for future residents of the Skyline Heights community and the City. 3-2

3.2 LAND USE CONCEPT
The project allows up to 276 single-family dwelling units located within three residential planning areas zoned for low density residential development. Exhibit 3-1, Land Use Plan, depicts the uses allowed within Skyline Heights.

The residential areas are designed to provide a diverse single-family community with beautiful views of the surrounding hillsides.

In addition to the residential community, a public park is also proposed along a significant ridge within the site with outstanding vistas and access to surrounding trails. The public park amenities will include a kite park with a large turf area and sail shade overhead structure with picnic tables, fitness park with bench seating, a main ridgeline park area with a parking lot, four pickle ball courts, two basketball courts, a pump track, bike track, bike service station, bike racks, tot lot, two barbeque/picnic areas with shaded seating, restrooms, small and large dog parks, sidewalks, trails for hiking and bicycling and elevated pedestrian crosswalks.

3.2.1 Residential Land Uses
The Skyline Heights Specific Plan establishes two residential districts, Single-Family Detached and Single-Family Detached Cluster, across three planning areas. The residential districts allow for a mix of housing product types including traditional detached single-family residential dwellings and detached condominium dwellings.

The residential districts also allow for the development of public and private parks, recreation amenities, open space and necessary infrastructure to support the Skyline Heights community such as water tanks and telecommunications facilities. The specific permitted uses are under Sections 3 and 4 of the Specific Plan. All lots including condominium lots proposed within the Specific Plan shall be a minimum of 7,200 square feet.

PA 1 - Single-Family Detached (SFD) Cluster
The SFD Cluster zoning is intended for the development of clustered single-family detached condominium homes on condominium lots that are a minimum of 7,200 square feet in area. A typical unit will have exclusive use areas comprised of fenced-in yards for privacy and vehicular access to a two-car garage from a shared private drive.

3.2.2 Open Space and Recreation Uses
Open Space Concept
The Skyline Heights Specific Plan includes public and private open space and recreation facilities.

Approximately 121.9 acres, (48.9% of the Specific Plan Area) is devoted to natural open space, made accessible from several trail heads within the project area. Approximately 49.07 acres will be manufactured slopes and open space areas that will be planted with native plant material and plant material that will meet fuel modification requirements. An additional 11.42 acres of the site will be improved as public and private parks. The parks and open space concept for the Skyline Heights development is reflected on Exhibit 3-2, Parks and Open Space.

The open space and recreation concept has been designed to provide public accessible park areas with active and passive amenities. The concept preserves the site’s natural resources, and wherever possible, integrates them as recreational elements by connecting them with improved trails or as visual amenities for the public and future residents of Skyline Heights.

Public Park
Based on the Quimby Act Park Requirements for the City of Corona (3.0 acres per 1,000 population), 276 single-family homes with an average occupancy of 3.57 persons per household (pph) according to the Housing Element of the City of Corona General Plan, the proposed project requires 3.13 acres of parkland.

The Skyline Specific Plan provides 9.25 acres of public parkland. 3.61 acres of the total parkland area will be retained in a natural state and the remaining 5.64 acres will be improved with passive and active amenities, consistent with the City of Corona Park Master Plan.

A centrally located public park site consisting of a total of 9.25 acres, will be improved within PA 2. The completion of the Park shall be specified in the Park Development Agreement. The park area and facilities, including the kite park and facilities and the main park area with the pickle ball courts, basketball courts, pump track, bike track, tot lot, barbeque/picnic areas, sidewalks, trails and related recreational facilities, a restroom and parking will be developed per the Park Development Agreement. All trail head and trail improvements for hiking and bicycling will be implemented concurrent with the development of the adjacent residential neighborhood. Exhibit 3-3, Public Park Plan, is an illustrative concept for the park site.

Natural Open Space
Approximately 121.9 acres of natural open space is included within the project area and integrated into the overall planning and community design of Skyline Heights to retain the natural character of the property and the surrounding area. The majority of the open space within the Skyline Heights Specific Plan area has been retained in its existing natural conditions and the grading and site development has purposely avoided significant natural features within the Specific Plan area, including steep slopes, biological sensitive areas and geotechnical sensitive areas.

In addition to preserved natural open space, uses allowed within this open space area may include debris and detention basins, drainage facilities, fuel modification areas, and access roads for future utilities, including future cellular communication facilities, and access roads for maintenance and fire safety. 3-4

Approximately 49.07 acres of the site area consists of manufactured landscaped slopes and interior graded open space areas. These areas also include access roads for slope maintenance, fire safety, and drainage facilities to manage run-off and provide erosion control. These areas will be planted pursuant to the Skyline Heights Specific Plan Community Design Guidelines and Exhibit 5-3.1, Conceptual Landscape Plan.

Manufactured Slopes will be consistent with the City’s landscape ordinance in Chapter 17.70 of the Corona Municipal and the Project’s approved Fuel Modification Plan, and will be maintained by the homeowner’s association.

Private Parks
Several local parks, pocket parks, and passive open spaces are provided within the residential neighborhoods of Skyline Heights for residents of the community to enjoy. They will provide areas for passive recreation and gathering places for neighborhood interaction. Amenities may include walkways, benches, picnic tables, barbeques, mailboxes and other passive recreational facilities. A dog park with overhead shade structures and play areas for small and large dogs and a neighborhood park with a minor trail head facility will be located within PA 3. Pocket parks will be implemented concurrent with the development of the adjacent residential neighborhood. These parks will be private and maintained by the Skyline Heights homeowner’s association.

3.3 CONCEPTUAL CIRCULATION PLAN

3.3.1 Roadways
Exhibit 3-5, Conceptual Circulation Plan, establishes a general layout and design standard of roadways for Skyline Heights to safely meet the transportation needs of the community.

The project proposes to take access to PA 1 from Foothill Parkway, approximately 100 feet north of Mabey Canyon. A second access to PA 2 and 3 along Foothill Parkway is proposed to the south of Mabey Canyon. This entrance would align with Border Avenue, a local street. This entry road, “B” Street, intersects with “A” Street which provides public access to a central community park. This park consists of three individual improved areas located along “E “ Street, a public street within the Skyline Heights Specific Plan area. “E” Street provides a connection road through the Phase 2 of the Specific Plan area, extending to a small residential enclave to “M” Street. “M” Street provides a third access/egress to the project from Trudy Way, an existing local street.

Cross sections of the streets within the Specific Plan area are shown on Exhibits 3-6A, 3-6B, 3-6C and 3-6D, Street Sections.

An emergency access (EVA) will be provided within PA 1 at the intersection of “P” Street and “N” Street, which connects to Mabey Canyon Drive to provide EVA access for surrounding residents and future residents. Access to Foothill Parkway for the adjacent residents will be provided through PA 1 via a 28’ wide private drive located at the end of “P” Street (See detail below):

The internal street system in PA 1 is comprised of two different street sections. Refer to Exhibits 3-5, 3-6A and 3-6E. The access at Foothill Parkway is an 88-foot wide, public modified secondary arterial which narrows to a 56-foot wide private street that provides access to two 56-foot wide private cul-de-sac streets.

The internal street system within PA 2 and PA 3 is comprised of five different public street sections. Refer to Exhibit 3-5, 3-6B, 3-6C, 3-6D and 3-6E. A 68-foot wide collector road provides access at Foothill Parkway; connecting to a 64-foot local street which provides access to the residential neighborhoods and extends to the public park. The residential neighborhoods are also served by 64-foot wide low volume local streets and 56-foot public cul de sac streets. The street within the public park will be a 52-foot wide modified local street, which restricts on-street parking.

Private common driveways are included within PA 1 and PA 3 to serve the cluster houses. The common drives will provide fire access and access to garages, which are hidden from the local streets.

The public streets within the Specific Plan area will install street lights in accordance with City standards.

Except at the entry from Foothill Parkway, within the public park, and in areas where sightline requirements cannot be met, public streets within the Specific Plan area will permit on-street parking.

3.3.2 Trails and Bikeways
The project site includes several improved and unimproved trails that traverse portions of the site that are proposed to be retained as permanent natural open space. A portion of the Skyline Ridge Trail is located within the natural open space in the southern portion of the site. Proposed trails and trail head improvements within the Skyline Heights Specific Plan will provide connectivity for hikers and bicyclists to the public park amenities and will allow connections to existing trails. This connectivity to the existing trails will allow public access to City owned properties and trails and connectivity from Foothill Parkway to the Skyline Ridge Trail. See Exhibit 3-7, Conceptual Trail Plan.

Master planned trail improvements are proposed within the project area. These improvements include major and minor trail heads and directional and safety signs. Improved public trails within the Skyline Heights Specific Plan area will be constructed according to the City of Corona Trails Master Plan. All master planned trails within the development area will be constructed to meet the cross sections in the City Master Plan.

A short, steep section of the trail, known as the Troy Lee Trail, is designated as a one-way bike trail to avoid conflicts with hikers. Separate trails for hikers and bicyclists are proposed along each side of the roadway within the public park. Two raised bike crossings at the road within the public park are designed to provide safe trail crossings for cyclists. See Exhibit 3-8, Conceptual Trail Improvements and Exhibit 3-9, Trail Heads and Signage Details.

3.4 PUBLIC FACILITIES
Sewer and water service is provided to the Skyline Heights Specific Plan area under the jurisdiction of the City of Corona’s Utilities Department.

Services and utilities for Skyline Heights will be provided through the overall development of the project by participating builders and developers. This Public Facilities section describes the general location, usage, and capacities of all services and facilities, which will be provided to the Skyline Heights community including water, reclaimed water, wastewater, and drainage. Conceptual Master Plans for water, reclaimed water, sewer, and drainage have been prepared to identify facilities needed for ultimate development of this project.

The Conceptual Utility Services Plans are included with this document as Sections 3.4.1, 3.4.2, 3.4.3, and 3.4.4.

3.4.1 Domestic Water Facilities
Background
Domestic water service for the Skyline Heights development will be served by the City of Corona and will be served by connecting to existing facilities and expanding the existing system. There is an existing 16-inch Zone 4 water line in Foothill Parkway, adjacent to the project site. This line has been extended to Mabey Canyon Road and dual 12-inch Zone 4 lines are installed in Mabey Canyon Road, north of Foothill Parkway. A 16-inch Zone 4 line is extended off Mabey Canyon Road to the Avenida Del Vista Reservoir site. The Avenida Del Vista Reservoir is located just north of Foothill Parkway, has a capacity of 1.6 million gallons and a high water line elevation of 1220 feet. Zone 4 is not proposed to provide direct service to any development within the Skyline Heights project, but it does provide a source of supply to the area.

Each residential unit will have its own individual water service and meter connected to the public water distribution system. Water service laterals and meters are to be located within the public right-of-way or within a public utility easement. Residential parkway landscaping will be irrigated with potable water supplied by the domestic water meter for the residence. Common landscaped areas such as HOA slopes shall have their own irrigation services and meters. These services and meters shall be located in public right-of-way or within a public utility easement.

There is an existing 16-inch Zone 5 water line in Foothill Parkway, adjacent to the project site. This line has been extended from the Zone 5 system to the southeast north to Green River Road. In the vicinity of the Project site, the Zone 5 system provides service to the residential tract that is adjacent to the southeast project boundary. The Zone 5 system also provides service to small pockets of development on the east side of Foothill Parkway. There are two existing Zone 5 reservoirs located southeast of the Project. The Eagle Glen Reservoir has a capacity of 2.0 million gallons and a high water line elevation of 1380 feet. The Gilbert Reservoir has a capacity of 4.7 million gallons and a high water line elevation of 1380 feet. The Zone 5 reservoirs are supplied by the Lester Booster Station, the Border Booster Station, and the Eagle Glen Booster Station.

Skyline Heights is located within Pressure Zones 5 and 6A. These pressure zones are shown on Exhibit 3-10, Conceptual Domestic Water Plan, and further defined as follows:

Water Pressure Zone Max Service Elevation Min Service Elevation Zone 5 (1,380) 1,260 1,100
Zone 6A (1,560) 1,440 1,260
Development Plan HEIGHTS
3-27
Conceptual Project Water Plan
The only area of the Project that can receive service from the Zone 5 system is the proposed development at the north end of the Project, north of Mabey Canyon. In updated City master planning efforts, the City has identified the need for an additional Zone 5 reservoir in this area to hydraulically balance the system with development in this area being located a significant distance from the existing Zone 5 storage tanks. The City has requested that a site for a 2.5 million gallon Zone 5 reservoir be located within the central portion of the Project site. A transmission line from the existing line in Foothill Parkway to the reservoir site is also be required.

The majority of the Project is above the service elevation range of the Zone 5 system and a new Zone 6A is proposed to be formed to serve the Project. The Zone 6A system will be formed by pumping from the new Zone 5 reservoir to an onsite Zone 6A tank with a proposed high water line elevation of 1560 feet. The Zone 6A tank is being sized to serve the Skyline Heights project only and requires a capacity of 0.372 million gallons so a 0.6 million-gallon tank is proposed.

The facilities proposed to serve the project’s domestic water demands are based on the needs of the two pressure zones and Corona DWP’s requirements for looping and valving. Final water demand and design of the proposed water lines/facilities shall be determined by the final Water Assessment approved by the City of Corona.

A more detailed description of improvements by pressure zone is provided below. a. Zone 5
The Zone 5 area of the project is proposed to be served by making connections to the existing 16-inch Zone 5 line in Foothill Parkway. In order to provide redundancy to this area of development, two connections are proposed to the line in Foothill Parkway with dual lines extended into the development area. Proposed development pad elevations in this area of the project range from 1185 feet to 1215 feet, resulting in maximum static pressures ranging from 71 psi to 84 psi with service from the Zone 5 system.

The City of Corona 2005 Master Plan indicates that the existing Zone 5 reservoirs have surplus capacity.

This surplus capacity could be used to meet the 0.05 MG storage needs of Zone 5 development within the Project. In updated City master planning efforts, however, the city has identified the need for an additional Zone 5 reservoir in this area to hydraulically balance the system with development in this area being located a significant distance from the existing Zone 5 storage tanks.

The City has requested that a site for a 2.5 million gallon Zone 5 reservoir be located within or adjacent to the Project site. A transmission line from the existing line in Foothill Parkway to the reservoir site would also be required. The Developer will be responsible for the fair share of costs of the construction of the Zone 5 reservoir. 3-28
b. Zone 6A
The Zone 6A system will be formed by pumping from the new Zone 5 reservoir to an onsite Zone 6A tank with a proposed high water line elevation of 1560 feet. The proposed range of pad elevations in the service area is 1218 feet to 1412 feet which results in maximum static pressures ranging from 64 psi to 148 psi with service from the Zone 6A tank.

The Zone 6A tank is being sized to serve the Skyline Heights project only and requires a minimum capacity of

0.372 million gallons so a 0.6 million-gallon tank is proposed. The Zone 6A Booster Station is proposed to be located at the Zone 5 Reservoir site and must have a minimum capacity of 215 gpm to meet the maximum day demands of development within the service area. A booster station with a capacity of 500 gpm is proposed and will consist of a duty pump and standby pump, each rated for this capacity.

Metropolitan Water District
An existing Metropolitan Water District water line (MWD Lower Feeder) traverses the City parcel adjacent to Green River Road. This 108-inch water line provides District water to Orange County. The Skyline Heights entrance road must cross the line pursuant to the requirements and recommendations of the Metropolitan Water District. The project proposes a bridge structure over the water line, which is intended to reduce impacts and protect of the MWD water line.

Currently the majority of the project is located within the Service Area Boundary of MWD and the Western Municipal Water District (WMWD). However, the most southerly portion of the property, Assessor Parcel No. 275-020-005, is currently located outside of the Service Area Boundary. This parcel is located within the sphere of inference of both districts. Prior to map recordation to this portion of the project this parcel must be annexed into both the MWD and the WMWD service areas.

3.4.2 Reclaimed Water Facilities
Reclaimed water service for Skyline Heights will be provided by the City of Corona and will include connections to existing facilities and development of new facilities. The 1380 Zone (Zone 3) is currently supplied by the WRF 3 Booster Station and Border Avenue Booster Station. The primary source of Zone 3 reclaimed water in the vicinity of the project is the 12–inch waterline in Foothill Parkway adjacent to the project. The project will connect to the existing 12-inch line at two locations and extend reclaimed water to the project.

The Phase 1 portion of the project can receive service directly from the 1380 Zone. Phase 2 and Phase 3 will require service from a newly formed 1650 Zone. A connection to the existing 12-inch will be made at the entry to Phase 1 and a new reclaimed water line will be extended into the project to serve this area. A second connection will be made at Border Avenue and extended into the project. A proposed 1380/1650 Zone closed booster station is proposed along Border Avenue within the project to boost pressures in the system to supply reclaimed water to the upper elevations of the project. See Exhibit 3-11, Conceptual Reclaimed Water Plan for facility locations.

The primary use of reclaimed water for the project with be for the landscape irrigation of HOA slopes and CFD irrigated areas. Reclaimed water will also be used for landscaping at the park site. The backbone reclaimed water system will be extended to the location of the landscape meters. The onsite reclaimed water system will be public and will be operated and maintained by the City of Corona. Reclaimed water services will be located in public right-of-way or within a public utility easement.

3.4.3 Conceptual Wastewater Master Plan
Skyline Heights is located within the City of Corona Master sewer collection system that is tributary to the City’s Wastewater Treatment Plant No. 1. This plant has a capacity of approximately 13.5 mgd and the City has determined that this treatment plant has capacity to serve Skyline Heights. A gravity sewer system will be developed to provide sanitary sewer service to all proposed lots within Skyline Heights.

The project site is broken up into three drainage areas. The northern drainage area consists of the proposed 104 lots within Phase 1 of the Project. Flows from these lots are proposed to include an offsite sewer line in Foothill Parkway and Mabey Canyon Road to the existing 8-inch sewer line in Mabey Canyon Road. The central portion of the project consists of the majority of Phase 2 and all of Phase 3 and flow from this area will be conveyed to Foothill Parkway at Border Avenue. An offsite 8-inch sewer line is proposed to convey flow north in Border Avenue to the existing 8-inch sewer line. The southern area of the project includes 17 units within Phase 2 that will convey sewer south to the existing sewer line in Trudy Way. See Exhibit 3-12, Conceptual Wastewater Plan.

Flows from 104 units will be connected to the existing system at Mabey Canyon Road. Flows from 155 units will be connected to the existing system at Border Avenue. Flows from 17 lots will be connected to the existing system at Trudy Way.

Sewer from the project will be conveyed through several miles of existing offsite sewer lines to get flows to Treatment Plant 1.

The City of Corona is in the process of updating their Sewer Master Plan. As part of that effort, the City evaluated the impact of the project flows on the offsite sewer system.

This sewer system shall be constructed in accordance with the City of Corona Utilities Department standard requirements and design criteria. The sewer system shall consist of 8- inch sewer mains, service laterals and manholes, which will be located within a dedicated public sewer and water easement within the private street system of the project. This wastewater system is expected to be owned and operated by the City of Corona.

Each residential unit will have its own individual sewer service lateral connected to the public sewer collection system. Sewer service laterals are to be located within the public right-of-way or within a public utility easement.

3.4.4 Conceptual Drainage Master Plan

1. Existing Drainage Conditions
The existing condition of the site consists of hillside terrain with distinct ridges and canyons. The majority of the site is tributary to the west through three minor canyons, which discharge into existing drainage facilities. The high point ridge between the two tributaries primarily divides the project envelope into north and south halves. The remainder of the site, that outside of the development envelop and is not tributary to the two minor canyons described above, will remain undeveloped and undisturbed leaving the existing drainage patterns undisturbed.

2. Drainage Plan
A storm drain system will be constructed in conjunction with the grading of Skyline Heights. This storm drain system will be a publicly maintained system and will be designed in accordance with the standard requirements of the City of Corona.

This storm drain system is illustrated on Exhibit 3-13, Conceptual Storm Drain Plan. This system will consist of drainage inlets to intercept runoff from the undeveloped open space areas, catch basins within the roadways to intercept runoff within streets, storm drain structures and manholes, storm drain pipelines and outlet facilities into four proposed water quality basins. These basins will discharge into four existing inlet facilities and the city storm drain system. At both discharge points to the city system, the existing capacities for each storm drain system should be able to adequately accept the site’s 100-year flow rates. Therefore, no flood control detention basins are proposed on site.

Planning Area 2 is undeveloped at this time and has a separate tributary drainage area than Planning Area

1. As such, a majority of the runoff from this area will maintain its current route but, a small portion of the developed increased runoff will be routed through the Planning Area 1 storm drain system. Planning Area 2 will be required to independently treat their developed flows per current city ordinances and stormwater permits.

3. Water Quality
A Notice of Intent (NOI), Storm Water Pollution Prevention Plan (SWPPP), and Water Quality Management Plan (WQMP) shall be provided in accordance with the requirements of the City of Corona and the Regional Water Quality Control Board.

Skyline Heights will comply with the current water quality requirements and regulations from these agencies(1).

Best Management Practices (BMP’s) shall be implemented for Skyline Heights to provide water quality protection during grading operations, construction activities and post construction activities. Permanent BMP’s for post construction mitigation shall primarily consist of extended detention basins at the primary discharge points near the perimeter of the project. Other BMP’s may be available and these improvements, if any, will be identified in the development of the site-specific SWPPP and WQMP for this project.

All water quality facilities shall be maintained by the HOA. The proposed BMP’s for Skyline Heights are illustrated on the Conceptual Storm Drain Master Plan.

Development Plan HEIGHTS

The municipal separate storm sewer system National Pollutant Discharge Elimination System permit (MS4 Permit) applicable within Riverside County is: Order No. R8-2002-0011, NPDES No. CAS 618033 adopted by the Santa Ana Regional Water Quality Control Board on October 25, 2002. 3-36

3.4.5 Fire and Police Protection
Fire Protection
Fire Protection will be provided by the City of Corona Fire Department. Fire Station 6 is the closest fire station, located at 110 W Upper Drive, Corona, CA, and will provide service for the Skyline Heights Specific Plan area.

The project will comply with the City of Corona Fire Department regarding design standards and fire protection requirements. Because Skyline Heights is within the Wildland Interface Zone, fuel modification areas are required for any structures adjacent to natural open space, on- or off-site.

Police Protection
Police protection will be provided by the City of Corona Police Department. Police services will be from the main police station located at 730 Public Safety Drive in downtown Corona.

3.4.6 Public Facilities Requirements
The following public facilities requirements shall apply to all development areas of Skyline Heights:
1) Utility easements will be provided as required to facilitate an safe and efficient service network within the project area.
2) Except for high voltage transmission lines (34 KV and larger), all utility lines shall be underground. 3) All flood controlling measures shall be provided in accordance with the requirements of the City of Corona.

3.4.7 Public Schools
The designated school district for the Skyline Heights Specific Plan area is Corona/Norco Unified School District, which serves grades K-12.

3.4.8 Public Utilities
Southern California Edison and Southern California Gas Company are the designated providers for electricity and natural gas, respectively.

3.5 GRADING CONCEPT
All grading shall be in conformance with the City of Corona Grading Ordinance and the Visual Resource Policies of the General Plan. The conceptual grading design for Skyline Heights is intended to achieve several project objectives including:
• Create a scenic living environment for residents.
• Be responsive to the natural landforms both on and off-site. • Ease the visual impacts of grading.
• Stabilize manufactured slopes.

Development Plan HEIGHTS
3-37
To achieve these objectives a number of techniques have been incorporated into the grading design of the project, including contouring techniques, which soften the visual appearance of manufactured slopes, and rounding of tops and toes of slopes. Landscaping will also be used to provide visual softening of slope areas.

The following guidelines and standards provide general direction to grading design as related to drainage, landforms and contour grading. The primary focus of these guidelines and standards is to ease the visual impacts of grading through the preservation of natural landforms and foster approaches to landform alteration, which are sensitive to the existing topographic features.

3.5.1 Grading Guidelines
The following guidelines will govern all Skyline Heights grading operations:
1) Skyline Heights shall comply with the Corona General Plan hillside preservation policies by clustering development and preserving the steeper slopes in natural open space. 2) Where cut and fill slopes are created in excess of four (4) feet in vertical height, detailed landscaping plans shall be submitted to the City of Corona per Corona Municipal Code Chapter 17.70. These plans shall be submitted as part of the landscape plans required for subdivision. 3) The applicant and/or developer shall be responsible for the maintenance and upkeep of all slope planting and irrigation systems until such time as those operations are the responsibility of other parties. 4) Angular forms shall be discouraged. The graded form shall reflect the natural rounded terrain. 5) No grading shall extend outside of the Specific Plan boundary into the Cleveland National Forest.

No off-site grading on private property shall occur without both the property owner’s written consent and the establishment of a maintenance program for the subject area approved by the City.

16) Geotechnically acceptable methods of slope erosion control shall be used to protect the slopes from erosion until a healthy plant growth can be established. 17) Daylight cuts should be used where possible.

3.6 PHASING
Skyline Heights may potentially develop in two phases. Exhibit 3-14, Construction Phasing depicts each of the infrastructure improvements for each phase. Adjustments to the construction phasing of the Skyline Heights Project Site may be approved by the Planning Director pursuant to Section 6.9 of this Specific Plan, provided that the related infrastructure is adequately in place. Infrastructure construction phasing will be provided as needed for each individual phase. Although the entire site will be graded in Phase 1, along with the drainage facilities required to manage the storm flows, the remaining infrastructure items like sewer and water facilities and access will be constructed as shown on Exhibits 3-10 to 3-13.

All of the associated infrastructure including retention basins, water tanks, booster stations within the boundary areas of Phase 1 and Phase 2 will be developed concurrently with that Phase. All improvement plans will be reviewed and approved by the City of Corona.

As phasing of subsurface utilities and infrastructure are constructed, consideration for future phased nearby facilities shall be considered so as to not create future obstructions or interruptions of service. Phasing shall be completed in order; Phase 1 will precede Phase 2.

Community Design Guidelines HEIGHTS
5-1
SECTION 5 - COMMUNITY DESIGN GUIDELINES

5.1 PURPOSE AND INTENT
The Skyline Heights Community Design Guidelines integrate architectural and landscape design standards, which establish and reinforce the overall theme and framework intended for the Skyline Heights Specific Plan.

As guidelines, they provide a basis for developers and builders in preparing final project designs and they also provide criteria to be used by City staff when considering the appropriateness of future architectural and landscape design submittals.

The proposed project tract is located within a “Wildland-Urban Interface Fire Area” (Fire Hazard Severity Zone) as depicted in the City of Corona Fire and CalFire Maps. All new construction shall be designed to comply with requirements for materials and construction methods for exterior wildlife exposure (2022 CRC, section R337/2022 CBC, chapter 7A). Construction plans shall specify compliance on all parts of the plans as required, including but not limited to general notes, elevation views, and construction details.

A thoughtful design theme that establishes a cohesive community character and aesthetic treatment will help create a distinct sense of place for Skyline Heights. The architectural and landscape elements identified in this section of the Specific Plan, when implemented, will establish a cohesive and attractive community within Skyline Heights.

The Community Design Guidelines serve the following functions:
1) Establishing architectural and landscape design guidelines for Skyline Heights. 2) Providing developers, builders and homeowners with guidelines and recommendations, to create and maintain a cohesive and harmonious aesthetic character and overall sense of place, while allowing for flexibility in interpretation to facilitate future innovations in planning, architecture, and landscape architecture that meet the intent of the City’s General Plan and the Skyline Heights Specific Plan.

All design considerations, including access and circulation, visibility, building orientation, fuel modification, planting, lighting, and landscaping standards, shall be consistent with current adopted codes and reviewed through tract maps, precise plans, and design review as submitted to City staff.

The design concepts and associated community design guidelines are also intended to encourage quality design and development. The following overview of the design concepts provides a foundation for the interpretation of the community design, architectural character, and landscape treatment within the Skyline Heights Specific Plan. 5-2

5.2 ARCHITECTURAL DESIGN GUIDELINES
The purpose of the Architectural Design Guidelines section is to provide general design criteria for the residential component of Skyline Heights.

5.2.1 General Guidelines
This section includes design standards for residential development to encourage a safe and attractive pedestrian-oriented neighborhood environment and an interactive and interesting street character within Skyline Heights. The guidelines are intended to promote diverse mixture of homes compatible with the traditional themed community landscape elements. The general architectural character for Skyline Heights incorporates a variety of architectural styles that harmonize with the surrounding neighborhoods. These guidelines are not intended to require historically accurate design and detailing or rigid adherence to regional or period-style descriptions, but are intended to reinforce the community theme and ensure architectural compatibility and high-quality construction.

The overall community character and architectural theme of the Skyline Heights Specific Plan will be viewed from surrounding residential areas, from Foothill Parkway, and from accessible trails and natural open space vistas around the proposed development area. Within Skyline Heights, the community character will be defined by the aesthetics and quality of design, as it is viewed from public spaces such as local streets, sidewalks, open spaces, and both public and private parks. Therefore, the overall building form, including massing, scale, and roof designs as the primary design components, require careful articulation in their architectural expression to the public spaces.

The following appropriate and inappropriate architectural massing shall determine, if a development meets the general architectural criteria:

Appropriate:
1) Articulation of wall planes.
2) Projections and recesses to provide shadow and depth. 3) Well-defined entries.
4) Traditional architectural forms.

Inappropriate:
1) Vast expanses of wall surface without horizontal and vertical wall articulation. 2) Steeply pitched or flat roofs (more than 10:12 or less than 2:12).

The articulation of building facades and variation in rooflines creates visual interest, architectural identity, and a human scale in residential architecture. When developing building plans, consideration should be given to massing forms, architectural elements, features, and details that appropriately create an interesting street scene, reinforce the intended architectural style and provide a friendly, pedestrian character within each residential neighborhood.

Community Design Guidelines HEIGHTS
5-3
Large, unarticulated building masses shall be avoided, with particular attention given to the scale of the building, the elevation character, context, and relationship to the street. Each house should incorporate details to create an enhanced entry, balanced and articulated front elevation. Architectural features such as accent roofs, building offsets and projections, fenestration/articulation, recesses and porches should be utilized to create an attractive neighborhood character to optimize visual interest and scale.

5.2.2 Site Criteria
Plotting Concepts
A range of dwelling unit sizes, floor plans, elevations, and unit sizes shall be provided within the Specific Plan area. The following criteria shall be considered when plotting single-family houses and detached condominium buildings:
1) A minimum of three (3) floor plans are required for a maximum of one hundred and fifty (150) lots. One (1) additional plan shall be required for every addition of sixty (60) lots. Three (3) elevations minimum shall be provided for each floor plan.
2) A floor plan/elevation shall not be used on adjacent lots along the same street more than two (2) times in a row, including reverse floor plans, unless approved by the Planning Department. 3) No two (2) adjacent houses with the same style shall have the same exterior color scheme. 4) Plotting garages and living space adjacent to each other are encouraged to pair entries along the street and to improve opportunities for on-street parking, except on steep streets.

Varied Front Yard Setbacks
Variation in the front yard building setbacks to living space or porch between three (3) adjacent homes shall be a minimum of two feet (2’) on straight streets or blocks. Front building variations are not required on lots located on a curvilinear street, knuckle or cul-de-sac, which already provides for a varied street scene.

The garage setback does not need to vary between adjacent homes. In no case shall the garage setback be less than eighteen feet (18’).

VARIED FRONT YARD SETBACKS
5-4
Visible Rear Elevations
Houses plotted along open spaces provide view opportunities for residents, however, often the rear elevation of these houses are highly visible. The building form and the roofline are important design elements which can be used to enhance this important visual edge within the Skyline Heights Specific Plan area.

Building forms shall be varied to minimize the visual monotony of similar-sized houses and similar-ridge heights. Additional variety can be achieved by incorporating roof designs with a variety of front-to-rear and side-to-side ridgelines, by utilizing gables and hipped roofs, and by introducing single-story elements.

Rear facing gable roofs should not be plotted on more than two (2) adjacent houses along a street with visible rear elevations.

VISIBLE REAR ELEVATION EXAMPLES
Community Design Guidelines HEIGHTS
5-5

5.2.3 Building Forms
Building Massing and Scale
Building massing within the required setbacks literally establishes the foundation of the form of each home within the community. Simple building forms, assembled to create a functional floor plan, are the basis for building massing, utilizing varied building heights.
1) Large, unarticulated, two-story walls are discouraged on both front and rear elevations, unless they are a fundamental design element of the architectural style. 2) Articulation (projections and recesses) of wall planes of front elevations is required. 3) Rear elevations which are highly visible from any roadway or off-site open space shall be enhanced. 4) Roof forms along highly visible edges shall provide a variety of expressions to avoid repetitious building massing.
5) Single-story building elements along street frontages are encouraged.

Roofs
Roofs serve as major structural and architectural design element. A variety of roof types are permitted and encouraged within the community. Roofs shall be consistent with the architectural style of the home. 1) A variety of roofs shall be permitted, including but not limited to, hip, gable, and shed roofs. Varied roof pitch, materials, overhang and eave details contribute to the visual interest and architectural character of each house individually and to the overall community aesthetics within Skyline Heights. 2) It is encouraged to use the same roof pitch on the main roof of the building, but alternative pitches can be used at cross gables, one-story elements, balconies, and where appropriate to the architectural style. 3) Acceptable roof materials shall be Class A material.

Porches
Porches are encouraged to add visual interest and reinforce the architectural style of the house. They also help provide a pedestrian-friendly scale and opportunity for social interaction. Porch designs should be consistent with the architectural style of the front elevation of the house. 5-6
Front Courtyards
The Spanish Transitional, Tuscan Farmhouse, and Italian Revival styles adopted the use of front courtyards to define private space, create a sense of entry and to put eyes on the street. 1) A three and half feet (3½’) maximum courtyard wall is permitted in front yard areas, with a minimum three foot (3’) setback from the back of the sidewalk or private drive to allow for landscape planting. 2) Acceptable finish materials for courtyard walls include stucco, decorative masonry block, brick or stone veneer to match the architecture of the house.

Entries
The front entry to the homes in Skyline Heights should be articulated as a focal point of the building. Front doors that are visible from the street are encouraged. Entries should be enhanced and may be covered or recessed to reinforce the architectural character of the house. Architectural elements such as portals, towers, turrets, colonnades, enhanced door surrounds, and other features or details may be used to enhance entries and support the overall architectural theme of the community.

Balconies and Decks
Balconies, decks, and exterior stairs should be designed as integral components of the structure and should reflect the style of the home. These elements shall be integrated to break up large wall masses, offset floor setbacks, and add human scale to buildings. Balcony columns should match the column design on the house and pilasters should be provided at all corners to ensure that the balcony is integral to the house architecture.

Railing designs should be simple and support the architectural character of the house.

5.2.4 Exterior Materials and Finishes
Building materials and colors play an important role in providing visual interest and diversity and enhancing the street scene within each neighborhood within Skyline Heights. The exterior colors on individual homes will support the architectural style of the house, complement the surrounding houses, and avoid a repetitive street character with adjacent homes with the same colors. Exterior color schemes shall meet the following criteria:
1) A minimum of two (2) color schemes are required for each proposed elevation. 2) Front elevation design and materials shall wrap around the side elevation to an appropriate transition point or a minimum of three feet (3’).
3) Individual color schemes shall be appropriate to the architectural style. 4) Roof colors and materials shall be appropriate to the style. The use of different roof colors and materials for each style is encouraged.
5) Each color scheme shall have a minimum of three (3) paint colors appropriate to the style. Enhanced building materials such as stone or brick veneers may be used instead of a differentiating color. The use of additional colors for accents is encouraged.
6) All flashing, pipes, and metal vents shall be painted to match the adjacent building or roof surface and not accented. When gutters and downspouts are used as an architectural enhancement, they may be painted a contrasting color or finish to reinforce the architectural character of the house.

5.2.5 Garages
Garages and driveways can have a strong impact on residential streets. Neighborhoods should be designed to avoid repetitive streetscapes dominated by garage doors. Garage orientation and design shall prioritize minimizing the impact of garages and garage doors along the street. Garages within Skyline Heights shall meet the following criteria:
1) House designs should provide solutions to minimize the visual impact of garage doors, pedestrian conflicts with driveways and reduction in streetscape trees along neighborhood streets. Solutions include recessed garage doors, increased garage setbacks, side-oriented garages, narrow driveway approaches, common/shared driveways, courtyard walls and living areas push forward of the garage setback. 2) Garages along residential streets are encouraged to be recessed from the front of the main structure, courtyard or porch.
3) Garage doors that face onto residential streets shall be recessed a minimum of six inches (6”). 4) Garage door enhancements such as windows, accent hardware or carriage-style doors are encouraged. 5) No more than two (2) adjacent homes are allowed to repeat the same garage door style/treatment. 6) All garage doors shall be roll-up style.
7) Detached garages shall be compatible with the architectural style of the main house.

5.2.6 Doors and Windows
Window and door details including window trim/surrounds are strong design elements that reinforce the intended architectural style. They also provide visual interest and architectural enrichment to the exterior elevations of each house. The arrangement, balance, proportion, and details of windows and doors support the architectural style. In general, windows shall enhance rather than dominate the overall architectural character.
1) Window locations should create a balanced elevation on the front and rear of the house. 2) Windows with divided lights are required on front elevations and visible rear elevations, if they are appropriate to the style of the house. 3) Visible corner windows shall be enhanced with window trims and divided lights that match the front elevations of the structure.
4) All second-story windows shall be vertical or square proportions. Horizontal windows are not allowed on second floors.
5) Entry doors shall incorporate architectural detailing. 6) Accent shutters that support the architectural style of the house shall be proportionate to the window opening.

1. Spanish Transitional
Spanish Transitional – and related styles including Spanish Eclectic – is an adaptation of Mission Revival architecture, enriched with Mexican-influenced details and elements. The style has been reinterpreted during several historical periods, adapting to local building materials, climatic conditions and stylistic differenced in the level of ornamentation.

Architectural distinction is established through the use of tile roofs, stucco walls, simple, rustic wooden doors, and decorative tile or ironwork. House plans are simple and informal, commonly oriented around a courtyard. Front elevations lack ornamentation, and are simply articulated and detailed.

2. Transitional Craftsman
The Traditional Craftsman style is inspired by the country homes from the Arts and Crafts period of the early 20th century. This style became popular in southern California agricultural regions as the style reflected the character of a farmhouse estate.

The style is characterized by a low-pitched symmetrical roofline, generally featuring a large covered porch with heavy column supports. Predominantly wood, the houses tend to be painted deep, earthy colors.

Architectural details and decorative elements are often accented with enhanced materials or colors.

3. Tuscan Farmhouse
The hillsides of northern Italy provide the romantic backdrop for this simple agrarian architectural style.

The Tuscan Farmhouse style was derived from early Colonial architectural influences in Southern Europe based on the classic proportions interpreted with simpler forms and details. Tuscan Farmhouses are generally simple box forms, assembled and unified within a larger roof with simple moldings as ornamentation.

This old-world prototype was reinterpreted throughout Southern California, especially in planned communities where it provided a harmonious character with other Southern European styles selected for their suitability to the region’s milder climates. The shallow-pitched hipped roof often incorporates decorative brackets that identify this style.

4. Italian Revival
In the 1860s, Italian Revival was one of the fashionable architectural styles in the United States, emulating the formal palaces of the Italian Renaissance. Italian Revival architecture reflects a “Villa” design common in Southern European rural towns.

This style embraces an old-world character and redefines it as an eclectic classic style. The style is characterized by simple building with shallow-pitched hipped roofs supported by enhanced fascia decorations. Wrought iron detailing is included as embellishments on windows, porches, gated entries, and balconies.

5. European Cottage
The European Cottage style is a picturesque style derived from medieval Normandy and English architecture. The resulting inspired European Cottage became extremely popular in the United States in the 1920’s utilizing modern stone and brick veneer materials to replicate European building forms. The overall building massing combines variations of one- and two-story elements to create an asymmetrical overall building form. Other European styles evolved from the cottage influence including French Country and Normandy Farmhouse derivations.

6. Modern American Farmhouse
The Modern American Farmhouse evolved from an agrarian interpretation of New England architectural styles in the early expansion across the United States. The simplicity of this style, held up primarily by the building materials and strong building forms combined together in the most honest and straight forward expression of “home”.

The evolution of this this style to a modern vernacular expression has grown as home restorations and new construction both responded to the further progress in building materials and construction techniques. New England Monterey, Bungalow and other similar styles also mimic the architectural elements of the American Farmhouse.

7. Midwest Traditional
The Midwest Traditional style was an early interpretation of American styles influenced by New England Colonial styles such as Cape Cod, Shingle, and Farmhouse architecture and constructed as modest homes designed as simple and functional structures.

The Midwest Traditional vocabulary of simple gable roofs, clapboard or board and batten siding, horizontal siding with rectangular buildings combining one- and two-story massing with simple porch attachments became classic forms of this style across the Midwestern states. When introduced to Southern California, siding was replaced with stucco as a primary exterior building material, with siding utilized on ancillary building forms and as an accent or detail.

5.3 LANDSCAPE MASTER PLAN
The Landscape Master Plan has been developed to provide a distinctive landscape theme as a unifying element for the Skyline Heights community. The landscape concept for Skyline Heights is composed of several design elements. The Landscape Master Plan illustrates the overall theme by integrating the community entry, streetscapes, public and private parks, trails, and community walls into the design for Skyline Heights.

The Skyline Heights Landscape Master Plan and the following guidelines are intended within the Specific Plan area. All future landscaping shall comply with the Multiple Species Habitat Conservation Plan (MSHCP) and Urban-Wildlands Interface Guidelines requirements related to drainage, toxics, lighting, noise, barriers, invasive vegetation control, access, pets and grading/land development. Specifically, the following requirements shall apply:
• Storm water systems shall be designed to prevent the release of toxins, chemicals, petroleum products, invasive plant materials or other elements that might degrade or harm biological resources or ecosystem-wide processes within open space areas. This will be accomplished using a variety of methods including natural detention basins, grass swales or mechanical trapping devices. Regular maintenance shall occur to ensure effective operations of runoff control systems.
• As a component of future sales or rent agreements, an information pamphlet shall be prepared for each homeowner and will include avoidance of discharging toxins to downstream waters. • Street lighting, parking lot lighting and other project-related illumination sources shall be positioned, directed and shielded so as to avoid “light spill” into biological conservation areas. • Special edge treatments shall be implemented where development areas abut open space areas, including the installation of minimum 6-foot-tall exclusion fencing, which shall be subject to review and approval by the City of Corona.
• At the access points into biological open space areas, signage shall be posted notifying residents to remain on the designated trails and avoid disturbances to habitat and requiring all pets to be on leashes. • As a component of future sales or rent agreements, educational pamphlets shall be provided to occupants to inform them of potential impacts of uncontrolled pets on native habitats, to request residents to be good stewards of the land and to prevent or limit their domestic cats from openly hunting in the avoidance area. • No gates or other openings are allowed along rear yard fences that abut biological open space areas.

Landscape guidelines have been developed to assure continuity between the landscape and other community elements. Landscape shall be in conformance to the Landscape Master Plan (Exhibit 5-3.1).

The design objectives are:

A) Create and enhance a visually pleasing street scene along streets within the development.

B) Utilize landscaping to establish a strong project identity and to accentuate the main entrance.

C) Encourage landscape designs which promote energy conservation and discourage excessive water consumption, while maintaining a high level of aesthetic quality.

Areas within a prescribed landscape lot located along streets and slopes shall be maintained by a Homeowner’s Association or other acceptable entity as determined by the City of Corona prior to map recordation. These improvements shall generally be installed during construction of adjacent roadways as applicable; however, due to other practical considerations, adjustments to timing of landscape installation may be made pursuant to approval by the City.

Homeowners shall be provided with a list of native landscaping materials permitted within the development area.

These materials have been selected for their contribution to the Project theme, adaptability to local climatic and soil conditions and for their compatibility with the unique natural environment in the area.

Landscape Concept
The use of plant material, color, community walls, and earthen forms will be applied in strategic locations to define entrances, provide buffering and screening, and define the overall community character. The Community Entry is to be maintained by a Homeowner’s Association.

The architectural elements of the Skyline Heights community will be of Tuscan-Italianate style architecture. The elements include the walls, signage, kiosk, and mailbox structures. The systematic use of high-quality materials such as rustic stone veneer, sand-finish stucco, terra cotta clay tile, heavy timber beams stained a natural dark wood color, decorative precast concrete architectural elements, decorative pottery, and decorative ceramic tile are consistent with the Tuscan-Italianate style and provide a strong visual quality. This will contribute to continuity throughout the community.

The hardscape elements of the Skyline Heights community will consist of angular rubble stone veneer, natural flagstone, colored and stamped concrete, stucco, tumbled or “used” brick, and precast concrete elements. They are consistent with the Tuscan-Italianate style and will provide a strong visual quality. All hardscape materials shall be natural colored and consistent with Tuscan style architecture and landscape.

Planting is a significant design element through the community. Landscape shall be designed to reinforce the theme for the community by using plants that, through form, color and texture, emulate the Tuscan-Italianate feel of the community.

The County of Riverside MSHCP has identified invasive plants that should be removed from open space areas. This list shall be included in the CC&Rs prepared for the community. Plants on the MSHCP list will not be utilized in the common area and their use by future homeowners will be prohibited.

There are several areas that will be maintained by a Homeowner’s Association that are explained below.

Components of the overall Landscape Plan area are described in the following sections.

Community Entries
The design intent of the Community Entry Monument Walls (Exhibit 5-3.2) is to establish a strong sense of arrival at the community, to reinforce the residential character of Skyline Heights, and identify the public park facilities and trail opportunities within Skyline Heights.

The primary community entry is designed to introduce the theme and character of the Skyline Heights Specific Plan community and set the tone to be continued throughout the development. The Community Entry announces the Skyline Heights Specific Plan area and provides an understated arrival landmark to the community. The primary monument wall incorporates a decorative stone base with project signage supporting a ten feet (10’) tall Community Design Guidelines HEIGHTS

MONUMENT DETAILS
MONUMENT DETAILS EXHIBIT 5-3.2 COMMUNITY ENTRY MONUMENT WALLS vertical limestone pedestal with a community logo. The monument wall is placed within a setting of landscaped boulders, enhanced planting, and specimen trees.

The secondary monument replicates the character of the primary monument to reinforce the residential character of Skyline Heights and to harmonize with the natural surrounding open space.

The landscape design of the Primary Community Entry (Exhibits 5-3.3 and 5-3.4) creates a sense of arrival to the 5-28
community from Foothill Parkway. The entry landscaping incorporates the site’s topography featuring terraced walls as well as decorative planted pots and establishes a distinct residential character and scale for the Skyline Heights Specific Plan, Planning Areas 2 and 3. Shaded sidewalks flank the entry roadway which features a focal median tree and regularly spaced street trees.

Street trees within the Skyline Heights Specific Plan along Skyline Heights Drive shall enhance the natural native landscape environment. Suitable trees are Oaks (Southern Live, Valley, Scarlet, Holly, Cork, and California Live) and other trees from the Community Plant List. Parkways and landscape open spaces will be planted with groundcovers from the Community Plant List and will consist of low growing and native groundcover.

Shrubs from the Community Plant List will be utilized in parks and open space areas. Planting in this area will provide color and interest, emphasizing the native plants in the surrounding hills. Planting themes will incorporate informal massing and natural shrubs forms such as Rosemary, Lavender, and Sage, as well as succulents and water-wise plants like Agave, Aloe, and Bougainvillea. Informal open space and walkways will use pervious materials such as decomposed granite, rock/gravel and mulch.

Project Signage
The intent of signage within the Skyline Heights Specific Plan is to create an attractive informational and directional signage within the community and the public park and trail facilities. The design, size, materials, and color of the signage shall be consistent with the architectural style of the community and provide an overall unifying landscape element. All signage shall be reviewed with the development of the community through the Precise Plan review process prior to issuance of a permit for installation.

At the access points into biological open space areas, signage shall be posted notifying residents to remain on the designated trails, to avoid disturbances to habitat and requiring all pets to be on leashes.

Temporary sales, temporary directional, and construction related signage shall be permitted in accordance with the Corona Municipal Ordinance.

Mailbox Community Area
Community mailbox areas where residents collect their mail and post community related information shall consist of an ornamental mailbox enclosure that is harmonious with the architectural character of the surrounding homes. The mailbox enclosures will be constructed with quality materials and subject to the approval of the US Postmaster and the City of Corona.

5.3.1 Streetscapes
A single tree species will be used for individual streets to provide a sense of neighborhood identity and enhance the beauty of the streetscape. Street trees will provide shade and encourage pedestrian activity and social interaction. The tree species identified for each street within Skyline Heights is shown on Exhibit 5-3.5.

Street tree spacing shall be an average of 35 feet (35’) on center, according to the City of Corona standards.

Landscaped Street Sections (Exhibits 5-3.6 through 5-3.12) depict the landscape treatment for streets within the Skyline Heights Specific Plan.

Street Trees
Within the project limits, street trees will be selected to provide the following criteria:
a) All street trees will be selected from the City of Corona approved tree list. b) Moderate shade in the summer and early fall months.
c) Taller branching pattern to allow for pedestrians to walk under the trees. d) Generally deep roots to avoid damage to adjacent walkways, etc. e) Compatibility with parkway plant material.
f) Mature height and girth appropriate to a residential scale. g) Natural growth habit requiring minimal shaping of form.

Additional trees not on the Community Plant List are permitted, subject to the approval of the City of Corona, as long as they meet fuel modification and other fire safety standards and are not considered to be invasive.

Parkways
Parkways will be planted with a single species of groundcover for each street to reinforce the sense of place and neighborhood identity. Species will be native groundcovers and low water use groundcovers chosen from the Community Plant List. Groundcovers not on this list are permitted, subject to approval from the City of Corona and if they meet fuel modification standards.

5.3.2 Landscape Medians
The design intent of the medians located within Skyline Heights is to unify the landscape of the community through the use of consistent hardscape and landscape elements. The design of the median provides a sense of continuity within the development theme. Planting in the median consists of low groundcovers selected from the approved Community Plant List.

5.3.3 Public Parks
The Skyline Heights Landscape Master Plan is oriented around a central public Community Park that will be maintained by the City. The Public Community Park Plans (Exhibit 5-3.13 and 5-3.14) depict the improvements within the Kite Park and the main Community Park. The public facilities include a kite park and facilities as well as the core park area with pickle ball courts, basketball courts, pump park, skate board park, children’s adventure area, related recreational facilities, a public restroom, and parking. Plant material and landscape/hardscape design elements and features will be consistent with the rest of the park and the overall community. Planting shall establish and reinforce the landscape and community theme. The plant selections should be made from the Community Plant List.

Three raised crosswalks are incorporated into the public park and bike trail interface area to provide for safe and efficient connectivity between the public park areas, public parking area and trail head locations within Skyline Heights. The Bike Crossing With Protected Bike Lane (Exhibit 5-3-15) depicts the elevated crossing.

5.3.4 Private Neighborhood Parks
The Skyline Heights Landscape Master Plan contains a private neighborhood park and pocket parks that will be maintained by the Homeowner’s Association. The private neighborhood parks and pocket parks are shown on Exhibits 5-3.16 and 5-3.17 and are intended for passive recreation. Private parks include pocket parks with informal walkways and turf areas for small gatherings or lawn games and trail head areas to provide amenities and informational signage for hikers. Plant material and landscape/hardscape design elements and features will be consistent with the rest of the park and the overall community. Planting shall establish and reinforce the landscape and community theme. The plant selections should be made from the Community Plant List.

5.3.5 Manufactured Slopes
Manufactured slopes within the residential development pads and along the project perimeter are proposed to be planted with selected shrubs and groundcovers from the Community Plant List to provide erosion control and slope stabilization. The overall intent is to provide slope stabilization, preserve views where extant, and enhance the exterior landscape scene. Landscape areas on manufactured slopes shall be permanently irrigated.

All slopes in excess of four vertical feet (4’) shall be landscaped per the Corona Fire Department approved Fire Modification Plan. Slopes shall be permanently landscaped with erosion control, drought-tolerant plant material, permanent paved surfaces, retaining walls, or other permanent erosion control methods, approved by the City of Corona. Slope landscaping will consist of small tree groupings, informal massing of low growing shrubs, and native groundcovers selected from the Community Plant List. Accent shrubs will be used near the streets and at focal points such as trail heads and roadway crossings.

5.3.6 Neighborhood Landscape Design Guidelines
The general intent of these Landscape Design Guidelines is to provide an attractive and sustainable landscape concept including landscape design criteria and appropriate plant material that complements and reinforces the overall theme for Skyline Heights. The plant material selection should consider water use/drought tolerance, landscape aesthetics, slope stabilization, and fire safety/fuel modification. Turf areas should be limited to useable recreational spaces in common areas.

Landscape plans for areas that are adjacent to the MSHCP Conservation Area, shall avoid invasive, non-native plant species listed as “prohibited” on the Community Plant List (Table 5-3).

5.3.7 Irrigation System Standards
All public, Homeowner’s Association, and private front yard landscapes shall have automatic irrigation systems installed. These systems shall provide irrigation to landscapes in a safe and efficient manner. All irrigation installations shall conform to all applicable City of Corona standards. 1) Systems shall employ permanent automatic controllers and below-grade supply lines. 2) All systems should be designed so that areas of separate maintenance responsibility can be controlled independently to the extent practical.
3) Systems should use low precipitation rate spray heads, laid out and selected to minimize water waste due to over-spray or airborne misting, and designed to adjust water output to water use requirements of plant material to the extend practical.
4) Controller valves, check valves or anti-drain valves shall be used on long irrigation lines to minimize erosion and uncontrolled runoff due to line breakage.
5) Very low water use irrigations systems such as drip, bubbler, and micro-spray should be used in all areas except for turf.
6) Irrigation systems shall comply with all appropriate City of Corona codes and regulations. 5-52

5.3.8 Perimeter Walls and Fences
Community Walls and Fencing Concept
The Skyline Heights Specific Plan includes fence and wall selections to promote the community concept while providing an aesthetically pleasing buffer to adjacent property owners. The Conceptual Wall and Fence Plan (Exhibit 5-3.18) has specified locations for various types of walls and fences throughout the community.

Special edge treatments shall be implemented where development areas abut open space areas, including the installation of minimum 6-foot-tall exclusion fencing, which shall be subject to review and approval by the City of Corona.

No gates or other openings are allowed along rear yard walls or fences that abut biological open space areas.

Individual lots will be enclosed by a rear yard masonry wall where sound attenuation and privacy are desired.

Where views are to be preserved, view fencing will be installed. Glass or plexi-glass may be utilized as alternative view fencing materials for the residential lots for sound attenuation along Foothill Parkway. The location of the view fencing shall be installed in accordance with City of Corona standards. Wall heights and fence heights will be 6 feet (6’) maximum.

On-site basins will be enclosed per County of Riverside fencing requirements and guidelines.

In summary, the Plan provides for five fuel treatment zones; Zone 0, A, B, C and a Roadside Adjacent Defensible Space Zone. Zone 0, the ember-resistant zone (0 to 5 feet from structure) contains only non-combustible material.

Irrigated Zone A (5 to 30 feet from structure) is to create a defensible space for fire suppression forces to protect structures. It shall be free of all combustible construction and materials. It shall consist of level graded area at top or bottom of slope.

Zone B is another irrigated zone (30 to 100 feet from structure). It shall be cleared of all undesirable and combustible plant species and replaced with plants from the approved Fire-Resistant Plant List. This zone is to reduce flame lengths and is required on all slopes adjacent to Zone A. Zone C is the Thinning Zone (100 to 170 feet from structure) and requires thinning and removal of all dead, dying, and undesirable species.

The roadside-adjacent defensible space zone extends a minimum of 10 feet from the edge of any public or private roadway that may be used as access for fire-fighting apparatus or resources. Clear and remove flammable growth for a minimum of 10 feet on each side of the access roads. Additional clearance up to 50 feet may be required upon inspection per the Roadside Protection Zone (RPZ) distinction in the CFD Vegetation Management Guideline for New Construction Fuel Modification Plans and Maintenance Program (VMG). Required on all areas of Project.

SECTION 6 - IMPLEMENTATION AND ADMINISTRATIVE

PROCEDURES

6.1 INTRODUCTION
This Section sets forth the policies and procedures for the City of Corona’s review and approval of implementing development projects within the Skyline Heights Specific Plan area and describes the methods and procedures for interpreting and amending this Specific Plan as necessary.

All development within the Skyline Heights Specific Plan community is subject to the implementation procedures described in this Section. Additional information on implementation, including potential funding mechanisms, maintenance responsibilities, and monitoring activities, are also discussed in this Section.

6.1.1. Applicability
All development and proposed uses in the Specific Plan area shall comply with the Implementation Regulations set forth in this Specific Plan. Where conflicts exist between the Implementation Regulations contained in the Skyline Heights Specific Plan and those found in the City’s Zoning Ordinance, the standards in this Specific Plan shall take precedence. Procedures, notices, timelines and appeals not addressed in this Specific Plan shall be subject to the requirements of the City’s Municipal Code in effect at the time a project is submitted or as otherwise provided in an approved and effective development agreement for the site.

6.2 INFRASTRUCTURE FINANCING
Several techniques are available for financing the required improvements for the Skyline Heights Specific Plan area. The appropriate mechanism for implementing each improvement shall be tied to the construction schedule and established conditions of approval for implementing projects. The following is a summary of possible methods that could be used to finance Specific Plan improvements. There may be other sources available to finance improvement projects, such as special assessment districts, government grants, or various types of bonds not listed below.

6.2.1 Developer Funding
Certain onsite facilities and improvements are directly associated with various phases of development. It is reasonable to expect the developer, builder, or property owner to pay all or a majority of the costs associated with these facilities and improvements in order to secure development rights. Onsite local streets, utility connections from main trunk/service lines, and drainage facilities are examples of facilities and improvements typically required concurrent with development and often funded by the developer or builder.

6.2.2 Special Assessment Districts
A special assessment district may fund improvements within the entire Specific Plan area or smaller areas in the Specific Plan where special improvements are constructed that directly benefit only certain property owners. Special assessment districts may only be used to pay for projects that are of specific and direct benefit to the property owner being assessed. The amount of the assessment must directly relate to the amount of benefit received by the property owner.
6-2
This financing tool can be used for public improvements that directly benefit specific properties that are assessed to pay for the improvements at no risk to public agency general funds. One or more special assessment districts may be created for the Skyline Heights Specific Plan area to cover improvements such as landscaping, geotechnical maintenance and hazards, and lighting.

6.2.3 Community Facilities Districts (CFD)
The Mello-Roos Community Facilities Act of 1982 allows the creation of special districts authorized to levy a special tax and issue tax exempt bonds to finance public facilities and services. A community facilities district (CFD) may be initiated by the legislative body or by property owner petition and must be approved by a two-thirds majority of property owners or registered voters (if there are more than 12 registered voters living in the area).

Because there is no requirement to show special benefit, Mello-Roos levies may be used to fund improvements of general benefit, such as fire and police facilities, libraries, and parks, as well as improvements that benefit specific properties. The provision also allows the reallocation of cost burdens to alleviate untenable burdens on specific properties.

6.2.4 Impact Fees and Extractions
Appropriate fees and exactions shall be determined through the Development Agreement process. Those impact fees not determined by a Development Agreement shall be charges at the rate effective at the time payment is due. Any improvement expenses required by the City of Corona incurred by the developer, but which exceed the developer’s proportional responsibility or fair share of such expenses, may be reimbursed to the developer through a mutually agreeable mechanism.

6.2.5 Other Funding Sources
Other funding sources may be available to finance the various improvements associated with this Plan.

Other sources include federal, state, regional, or local government grants, public agency construction, private developer coalitions, or various types of bonds not previously identified.

6.3 MAINTENANCE AND OPERATIONS
Public and private improvements constructed within the Skyline Heights Specific Plan area shall be maintained through a combination of public and private entities as described in Table 6.1, Maintenance Entities.

A Homeowner’s Association (HOA) shall be established for the maintenance of privately-owned common area landscape improvements, private park facilities and slopes within areas of the Skyline Heights community.

Indication of more than one party responsible for maintenance of any facility on Table 6.1 infers that maintenance may be undertaken by one party or any combination of the listed parties, subject to a formal agreement.

The maintenance organization shall be determined prior to or concurrent with recordation of any final subdivision map. For areas in public ownership (such as public roadway ROWs), maintenance districts may fund the maintenance of these areas.

6.3.1 Private Maintenance
Each individual private property owner is responsible for maintenance of areas within private residential lots, as well as maintenance of the landscape strip on the frontage of residential lots when abutting a public street.

Implementation and Administrative Procedures HEIGHTS
6-3

6.3.2 Homeowners Association (HOA)
A Homeowners Association (HOA) shall be established for the maintenance of common area landscape improvements within the residential areas of the Skyline Heights Specific Plan. The HOA may assume ownership and maintenance responsibility for areas including, but not limited to: all common recreation, open space, private parks, WQMP basins, private roadways, fuel modification zones, major slopes, and landscaped areas. Any private roads or accesses (if needed), as well as associated roadway landscaping and hardscaping shall be maintained by an HOA or other public/private entity.

The HOA for the Skyline Heights Specific Plan will establish Covenants, Codes and Restrictions (CC&Rs) to implement and manage all properties and improvements that are owned or managed within the Specific Plan area. The creation of CC&R’s will provide assurance to the City that these areas will be maintained and enhanced for the enjoyment of future residents.

6.3.3 Local Agency Maintenance
All public infrastructure facilities, roadways, parks, trails and dedicated natural open space within the Skyline Heights Specific Plan area shall be designed and constructed to standards stated in this Specific Plan and will be entered into the City system of roads for operation and maintenance as approved by the City Council. All landscape within raised medians on public roadways shall be maintained by the City of Corona. Indication of more than one party responsible for maintenance of any facility on Table 6-1 infers that maintenance may be undertaken by one party or any combination of the listed parties, subject to a formal agreement. 6-4

General Plan Consistency Analysis HEIGHTS
7-1
SECTION 7 - GENERAL PLAN CONSISTENCY ANALYSIS

7.1 RELATIONSHIP TO THE GENERAL PLAN
The City of Corona and State law requires that the content of a Specific Plan include a discussion of the relationship of the Specific Plan to the goals and policies of the elements of the City’s General Plan.

This section provides the analysis necessary to demonstrate that the Skyline Heights Specific Plan is consistent with, and results in the implementation of, applicable goals and policies of the General Plan of the City of Corona.

7.2 LAND USE GOALS
GOAL LU-1: A community that contains a diversity of land uses that support the needs of and provides a high quality of life for its residents, sustains and enhances the City’s economy and fiscal balance, is supported by adequate community infrastructure and services, and is compatible with the environmental setting and resources.

CONSISTENCY: SP 2025-0001 is consistent with Goal LU-1 as the Specific Plan provides a master-planned development with 276 single-family homes and 11.42 acres of combined public and private park facilities which provides a high-quality community for its residents. SP 2025-0001 will provide infrastructure improvements, such as roadways, water, and sewer facilities necessary to sufficiently serve the project and not adversely impact the City’s fiscal condition, as well as ensure an appropriate and respectful interface with the environmental setting of the project site is provided.

GOAL LU-3: A development pattern that retains and complements the City’s important residential neighborhoods, commercial and industrial districts, and open spaces.

CONSISTENCY: SP 2025-0001 is consistent with Goal LU-3 as this Specific Plan establishes a development pattern that retains and complements the existing surrounding neighborhoods and open spaces. SP 2025-0001 provides 122 acres of natural open space that abut open space to the north and east. SP 2025-0001 provides 276 residential homes and abuts existing residential neighborhoods to the south and east.

GOAL LU-7: Residential neighborhoods that contain a diversity of housing and supporting uses to meet the needs of Corona’s residents that are designed to enhance livability and a high quality of life.

CONSISTENCY: SP 2025-0001 is consistent with Goal LU-7 as this Specific Plan offers a variety of residential product types, including detached and cluster products, designed to enhance livability, attainability and assist with meeting the housing needs of the City’s existing and future residents.

GOAL LU-9: Development of new residential neighborhoods that complement existing neighborhoods, contain a mix of neighborhood-supportive land uses, exhibit high quality architectural design, and ensure a high level of livability for their residents.

CONSISTENCY: SP 2025-0001 is consistent with Goal LU-9 as this Specific Plan establishes a residential neighborhood that complements existing low density single-family neighborhoods to the south and east. SP 2025-0001 contains supportive recreational land uses and provides high-walkability design standards to ensure a high level of livability for residents.
7-2
GOAL LU-16: Open spaces that provide Corona’s residents with opportunities to enjoy the natural environment, provide visual “relief ” from urban development, protect significant plant and animal habitats, and protect development from natural environmental hazards.

CONSISTENCY: SP 2025-0001 is consistent with Goal LU-16 as this Specific Plan preserves approximately 122 acres of natural open space within the western, eastern, and southern portions of the project site. The open space provides visual relief from surrounding development, protects various plan and animal habitats as analyzed in the certified EIR, and provides a buffer for the Skyline Heights development from natural environmental hazards.

GOAL LU-21: Development of a well-designed master-planned community through adoption and implementation of a specific plan with uses that would complement adjoining uses.

CONSISTENCY: SP 2025-0001 is consistent with Goal LU-21 as this Specific Plan provides a well-designed master-planned community consisting of 276 single-family homes, which would be supported by 11.42 acres of combined private and public park facilities and 122 acres of natural open space via the adoption and implementation of this Specific Plan.
