Document Description
The proposed Perrin Oak Ranch project (Project) is an Administrative Permit (AD) for a small winery facility. The Project site is located on 16168 Highland Valley Road in the Ramona Community Plan within the unincorporated County of San Diego. The site is subject to the General Plan Regional Category Rural, Land Use Designation Rural Lands 20 (RL-20). Zoning for the site is General Agricultural (A 72). The Project consists of a 25,000 square foot (SF) winery facility, 5,000 SF crush pad, 12,000 SF hospitality building, 1,500 SF climatized storage building, and 5 units of vineyard worker housing. The hospitality building would include a tasting room, event space, private tasting lounge, and retail sales and offices. The vineyards on site would supply 60% of grapes required for annual wine production volume, and staff up to 15 full-time and part-time employees. The winery would host up to 70 annual events for up to 250 people each, two annual wine release events, and one wine auction. The anticipated daily tours would be 75 people. Small winery facilities are authorized in the A72 Use Regulation upon approval of an Administrative Permit pursuant to Section 2723 of the Zoning Ordinance. The site is developed with 22 acres of vineyard. Access would be provided by three gated driveways connecting to Highland Valley Road. The Project would be served by on-site septic systems and the Ramona Municipal Water District.
