Document Description
The project site is located in the City of San Marcos in northern San Diego County in southern California. The regional location of the project site is shown in Figure 1. The 1.8-acre project site (Assessor’s Parcel Number 219-122-03-00) is located at the southwestern corner of North Las Posas Road and West Mission Road in the central portion of San Marcos, approximately 0.2 mile north of State Route 78. The project would include development of a 5,000 square foot food mart with a drive thru (3,800 square foot food mart and 1,200 square feet of retail), a 2,000 square foot car wash with a 1,000 square foot equipment room, and a 6,192 square foot gas station canopy with nine fuel dispensing stations (i.e., 18 fuel pumps). A total of 59 parking spaces would be provided with three being electric vehicle (EV) charging spaces, one being a vanpool EV parking space, and two being future clean air parking spaces. The chargers would be Level 2 chargers or better. Three of the 59 parking spaces would also be designated as accessible parking spaces. The proposed project would be developed on a currently vacant parcel of land with a current land use designation of MU3. The MU3 zone does not permit gas station, car wash, or food mart uses. Instead, the zone is intended for job-based mixed-use developments. Job-based mixed-use developments include commercial retail, business support services, offices, government uses, and restaurants. Therefore, the development of the project would require a General Plan Amendment and Rezone to Commercial (C) to allow for these uses. The project is requesting a Conditional Use Permit for the gas station use, drive through restaurant, and car wash. The City of San Marcos Municipal Code states that minimum spacing be 500 feet between gas stations. Portions of the proposed gas station property are closer than 500 feet to the existing gas station on the northeast corner of Mission Boulevard and Las Posas Road. The project includes a request for a variance to these spacing requirements.
