On September 5, 2018, the Napa County Planning Division received a request for a Use Permit Major Modification to an existing winery. The property is located at 7257 Silverado Trail and is zoned Agricultural Preserve (AP).
The changes requested with this Use Permit Major Modification include the following: construction of an approximately 2,685 square foot new structure for office and hospitality use; increase in annual permitted production capacity from 200,000 to 300,000 gallons per year; increase in the maximum daily tours and tastings permitted; modify an existing marketing program; and development of a new process wastewater system. The property for which the project is proposed is owned by the Duckhorn Wine Company.
