Ontrail Vineyards Micro-Winery Use Permit, P25-00139-UP
Solicitation # P25-00139-UP
A micro-winery use permit is proposed for a 13.33-acre parcel in Napa County under the name Ontrail Vineyards, with a three-phase development plan centered on producing up to 5,000 gallons of wine annually. Phase 1 involves converting an existing 1,951-square-foot barn into fermentation and aging space, while crushing occurs offsite and bottling is handled by a mobile service located south of the barn. The 529-square-foot farm labor office will be repurposed as a tasting room, allowing up to 10 visitors per day or 70 per week for guided tours, tastings, and retail sales, with on-premises wine consumption permitted on a 2,500-square-foot outdoor patio. Operations will run seven days a week from 8 a.m. to 5 p.m. for production and 9 a.m. to 6 p.m. for visitation, staffed by one full-time and one part-time employee, including an onsite owner-operator. Infrastructure improvements include four parking spaces—accessible, standard, and compact—along with a fire truck turnaround south of the staging area, an upgraded driveway meeting county standards, and reliance on an existing groundwater well and domestic wastewater system, with no process wastewater generated. Phase 2 allows for construction of either a 4,103-square-foot or 2,152-square-foot winery building, with the option to retain the original barn if the smaller structure is built, plus installation of five 5,000-gallon water tanks and removal of 0.13 acres of vineyard to accommodate the new building, along with an additional fire truck turnaround. Phase 3 envisions a 730-square-foot covered crush pad and implementation of either an on-site wastewater treatment system or a hold-and-haul system for process waste. Phases 2 and 3 may begin anytime after Phase 1 is completed, maintaining flexibility in the timeline for expansion.

Promise Winery
Solicitation # P22-00384
The Promise Winery project, located at 2000 Sage Canyon Road in St. Helena, California, involves a comprehensive request for a Use Permit, a Variance, and an Exception to Napa County Road and Street Standards. The development is structured in two distinct phases on a 62.56-acre parcel. Phase I focuses on establishing winery operations by converting and expanding an existing barn into a 2,794 sq. ft. production space and repurposing an accessory dwelling unit into a tasting room, with an initial production capacity of 5,000 gallons per year and a staff of five. Phase II expands the facility's capabilities to 30,000 gallons of annual production through the construction of 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. parking structure with an ADA restroom. Operational activities include daily tours and tastings limited to 15 visitors per day, as well as specific private marketing events. The project requires significant site improvements and mitigation strategies to address environmental and safety concerns. Infrastructure plans include widening the driveway, installing intervisible turnouts for emergency vehicle access, and implementing vegetation management to maintain sightlines. To address environmental impacts, the project includes a Mitigated Negative Declaration addressing biological and tribal cultural resources, alongside a plan to mitigate vegetation loss through a 3:1 acreage ratio. Water and wastewater management are critical components, with studies confirming groundwater availability and a plan for wastewater reuse in vineyard irrigation to comply with state discharge requirements. The development is subject to oversight by various agencies, including Napa County, Caltrans, and the Water Quality Control Board, with public hearings scheduled to address the proposed variances and environmental mitigations.
