Promise Winery

The project involves the development of Promise Winery in St. Helena, California, through a phased conversion and expansion of existing structures and the construction of new facilities to support wine production and public tastings. Phase I includes converting a 2,794 sq. ft. barn into a winery and a 1,268 sq. ft. accessory dwelling unit into a tasting room, with initial production of 5,000 gallons per year and three employees. Phase II escalates operations to 30,000 gallons annually, adds five employees, and introduces a 5,000 sq. ft. production cave, a 1,235 sq. ft. covered crush pad, a 1,040 sq. ft. mechanical enclosure, and a 900 sq. ft. unenclosed covered parking structure with an ADA-compliant restroom. The project also includes seven standard and two accessible parking spaces, driveway widening with intervisible turnouts, vegetation management for sightlines, signage, and two outdoor patios for wine consumption under state alcohol code provisions. A variance permits reduced setbacks for both existing and new structures, justified by topography and vegetation preservation, while an exception to Napa County Road and Street Standards allows narrower driveways with compensatory safety features like turnouts and sightline controls. Fire safety mandates include a 110,499-gallon water tank and full compliance with the California Fire Code, including sprinklers and defensible space. Environmental obligations require adherence to Caltrans NPDES regulations, submission of a Water Pollution Control Plan, erosion control BMPs, cultural resource protocols mandating immediate work stoppage upon artifact discovery, and compliance with CALGreen Tier 2 standards. Energy and transportation goals require a 15% reduction in Vehicle Miles Traveled through LED lighting, cover cropping, and biomass reuse. Outdoor lighting must be fully shielded, downward-facing, and motion-activated. Vegetation removal is subject to a 70% canopy retention standard, though the 3:1 mitigation ratio is waived due to land use designation. All work must be inspected and accepted by Napa County Planning, Engineering, Public Works, and Caltrans, with final approvals contingent on compliance with local, state, and environmental regulations. Submission of the application is governed by a January 31, 2025 deadline, with oversight coordinated through Hannah Spencer of Napa County’s Planning Division.
