Examples of Winery Project Descriptions and Conditions of Approval

Examples of winery project descriptions and conditions of approval per Permit Sonoma common practice.

Example of Project Description for Use Permit Application

  • A new winery building (two story, approx. 32,210 square feet) with a maximum annual case production of 60,000 cases. The winery building would be built into the hillside meadow in front of the wine caves, using a cut-and-fill, low-profile design. Grapes will be locally sourced from on-site, Sonoma County, and bordering counties. Case-good will stored off site at a local warehouse. All crushing, processing, aging, bottling, and storing of wine will be indoors. Features include processing area, bottling area, mechanical room, wine storage and tank areas, administrative offices, employee kitchen/breakroom, employee shower and locker room, a wine library, a commercial kitchen, employee and public restrooms, and two technical tasting rooms. Technical tasting rooms are used for business tastings’ with distributors, local restaurant and chefs.
  • A wine cave (approx. 20,720 square feet) for “wine vault storage”, meaning long-term aging of wine in barrels. The wine cave will be a Class II wine cave not open to the general public. The proposed wine cave will be 36 feet wide and 16 feet high. The wine cave will be constructed by cut-and-cover excavation. The wine cave structure will include cast-in-place foundations, stem walls and concrete slabs, and pre-cast tunnel arch segments. Soil material from the cave area will be used to fill over the top of the cut and cover cave. All of the soil generated from this excavation, as well as from other grading for the winery, would be placed in temporary stockpiles only on the west side of the project site. The applicants’ engineer, ________, estimate that approximately 15,843 cubic yards would be excavated from the cave area. Approximately 9,575 cubic yards would be placed over the cave once the pre-cast tunnel arches are set. This leaves approximately 6,268 cubic yards of spoils temporarily stockpiled on the west side of the project site to then be used for the winery building, driveway, and landscaping areas.
  • 20 agricultural promotional events per year (10 events with 30 guests, 5 events with 60 guests, and 5 events with 120 guests). No weddings, receptions, or concerts are proposed.
  • Participation in industry wide events totaling two event days per year with a maximum of 300 guests.
  • Food and wine pairing is proposed in the public tasting room, consistent with approval of similar requests and during agricultural promotional events.
  • 15 fulltime employees, 3 part time employees, and 6 seasonal employees for a total of 24 employees.
  • New parking areas include: 20 standard spaces, 4 handicap accessible spaces, and 58 overflow parking spaces (unmarked gravel area) plus 25 standard spaces, 2 handicap accessible spaces, and 21 overflow parking spaces (unmarked). Bicycle spaces are provided at a ratio of 1 bicycle space for every 5 vehicle spaces.
  • New winery wastewater disposal system with pre-treatment system and disposal via on-site vineyard irrigation system. The process waste will be pre-screened at collection points in the facility and directed to an aerobic treatment unit (manufacturer to be determined). The treatment unit will reduce waste strength and suspended solids to levels approved by the State Water Quality Control Board for surface irrigation. Treated wastewater will be pumped to a point of connection to the vineyard irrigation system. The process system will be subject to a Waste Discharge Permit issued by the State Water Quality Control Board, North Coast Region.
  • New domestic septic systems on project site to serve all employee and guest restrooms. The septic systems will be subject to a Septic Permit and Plans issued by the Well and Septic Section of Permit Sonoma.
  • Two existing driveways will be used with improvements required by the Department of Transportation and Public Works. Sight distance improvements will be subject to plans approved by the Department of Transportation and Public Works and an Encroachment Permit issued by the Engineering Section of Permit Sonoma.
  • Existing on-site wells to be used for all winery and domestic uses.
  • None of the existing vineyard will be removed to accommodate the proposed use or related site infrastructure.
  • The 42 acres of vineyard consists of Chardonnay (32 acres) and Pinot Noir (10 acres) grapes. The on-site vineyard produces 250 tons of grapes. The 32 acres of Chardonnay grapes will be processed on site. The 10 acres of Pinot Noir grapes remain under a long term lease by another local winery. The Winery Trip Generation Form prepared by ________, states approximately 720 tons of grapes would be imported to the project site from local areas in order to reach the maximum annual production capacity of 60,000 cases. This calculates to approximately 62 cases/ton, consistent with industry standards which range between 58 to 65 cases/ton depending upon the grape variety and processing operations.
