Document Description
Request for a Use Permit for a new, 66,000 square foot winery with public tasting, tours and incidental retail sales of wine, one marketing accommodation located on the second floor of the proposed winery facility, and participation in county wide wine tasting events. No winery exclusive events are proposed. An existing house will be converted into a temporary tasting room until the winery is complete. Appurtenant development includes new commercial access off to Bonneau Road, guest and employee parking lots, a mound-type sanitary wastewater disposal system, a process wastewater treatment pond, and other incidental structures for water storage and trash enclosures. Prior to occupancy of the winery, the temporary tasting room will demolished to provide sufficient area for the proposed pond. .08 acres of wetland will also be created to mitigate loss associated with the winery. The winery will maintain a maximum staff of 18 employees, and hours of operation shall be from 7 am to 6 pm Monday through Friday off harvest, and 6 am until 8 pm Monday through Sunday during the harvest season. Tasting room hours for both the winery and the temporary tasting room are from 10 am until 5 pm daily.
