Equestrian Facilities Project Equestrian Facilities Project Cuyamaca Rancho State Park Draft Environmental Impact Report SCH# 2007051074 February 2010 State of California – The Resources Agency DEPARTMENT OF PARKS AND RECREATION EXECUTIVE SUMMARY The purpose of the Cuyamaca Equestrian Facilities Project Environmental Impact Report (EIR) is to describe and allow full public review of the proposed project in accordance with the California Environmental Quality Act (CEQA). The California Department of Parks and Recreation (DPR) is the lead agency for the proposed project and prepared this document per CEQA, Public Resources Code §21000 et seq., and the State CEQA Guidelines, California Code of Regulations §15000 et seq. Organization of the EIR is addressed in Section 1.1. The main objective of the Cuyamaca Equestrian Facilities project is to construct amenities that will meet Cuyamaca Rancho State Park’s (Park) need for equestrian recreational opportunities. Although the Park supports several horseback riding trails, an equestrian group campground, and two equestrian day use areas, it does not currently have an equestrian family campground. The Park’s General Plan (DPR 1986) states that “the most well-defined recreation need [in the Park] is for horse/people camping.” The DPR mission includes the protection of natural and cultural resources, while providing high quality recreation. Therefore, an appropriate combination of resource impact avoidance, minimization, treatment, mitigation, and monitoring will be implemented throughout the project design, construction, operation, and maintenance phases. The proposed project includes four components: (1) the conversion of the Green Valley Family Campground Loop A (sites 1-22) to an equestrian campground containing 10-15 sites; (2) the construction and operation of a day use staging area at the site known as Paso Picacho East, referred to herein as the Paso Picacho Day Use Area; (3) the construction and operation of an expanded day use staging area within the site known as Merigan Ranch, referred to herein as the Descanso Area Development Interim Day Use Parking Area; and (4) the future construction and operation of a new equestrian campground and associated facilities within the Descanso Area Development site. The construction and operation of the Descanso Area Development will be completed in phases and evaluated in this EIR at the programmatic level, while the remaining three projects will be evaluated at the project specific level. Phase I of the Descanso Area Development is the construction of the day use area, which would be considered an interim facility until funding for the campground can be secured. Phase II of the Descanso Area Development would include construction of the equestrian campground and expansion of the Interim Day Use Parking Area. Phase II of the Descanso Area Development would require subsequent CEQA review. The Park is located in a rural and unincorporated portion of east central San Diego County. Much of the Park’s boundaries are adjacent to open space including Anza- Borrego Desert State Park and the Cleveland National Forest. The proposed project would occur at three discrete sites within the Park including from north to south (1) an area east of SR-79 in the vicinity of the Paso Picacho Campground; (2) Loop A of the Green Valley Campground, which is west of SR-79 in the southern third of the Park; and (3) off Viejas Boulevard adjacent to the community of Descanso at the southern boundary of the Park. An equestrian day use facility would be constructed at Sites 1 and Cuyamaca Rancho State Park Equestrian Facilities Project DEIR Page i January 2010 3, while a family equestrian campground and associated amenities would be constructed at Sites 2 and 3. The Park is approximately 24,623 acres in size and is open for hiking, nature watching, camping, mountain biking, and equestrian camping and trail riding. Since the mid-1940s, it has been a popular equestrian camping and trail riding destination. Equestrian facilities available in the Park include Los Vaqueros Group Horse Camp, Hual-Cu-Cuish Day Use Horse Parking Area, and Sweetwater Parking Area. Prior to 2003, the Park also contained the Los Caballos Equestrian Campground (Los Caballos). The 2003 Cedar Fire burned approximately 280,000 acres of land in San Diego County including a large portion of the Park. The fire destroyed or severely damaged 30 of the Park’s facilities including the restrooms, cabin, and storage buildings at Los Caballos. Due to the importance of both cultural and natural resources found at Los Caballos, the equestrian campground was closed. Since the closure of Los Caballos, there has been a need for equestrian camping facilities within the Park. All of the alternatives, except the No Project Alternative, have the potential to adversely affect aesthetics, air quality, archeological resources, biological resources, geology and soils, hydrology and water quality, and noise in the project area. The Preferred Alternative and the Environmentally Superior Alternative would mitigate all of these impacts, except aesthetics, to a level below significance, thereby preserving the wilderness experience of the Park. Potential adverse impacts to agriculture, hazards and hazardous materials, historical resources, land use and planning, paleontology, public services, recreation, utilities and services, population and housing, traffic, and mineral resources are insignificant but the proposed project has incorporated measures to minimize impacts or to meet established treatment protocols for these categories. Cumulative impacts are not anticipated to cause significant adverse environmental effects except to aesthetics.
