Winery Events

Currently, sales and promotional activities of agricultural products grown or processed in the County are allowed in agricultural zones with a use permit.

General Plan policies call for the development of regulations to further define compatible agricultural promotional activities including their permissible sizes and intensities. The General Plan also states that visitor-serving uses even if related to surrounding agricultural activities can be detrimental to the primary use of land for the production of food, fiber, and plant materials. The goal of the General Plan policies is to preserve agricultural lands and maintain the rural character of the area while enhancing the economic viability of farms. The Board of Supervisors directed staff to develop regulations addressing agricultural promotional events and potential overconcentration.

In June 2015, the Director of PRMD formed a group of industry representatives and neighborhood groups to advise staff on the key issues and policy options. The Working Group met for six months ending in early November and gave considerable insights into the business needs and the impacts of winery events to the local area. Staff will host a public workshop to provide a forum for input from other stakeholder groups and interested parties. After the public workshop, staff will complete the analysis of the policy options and will make a recommendation and host an additional workshop prior to conducting hearings before the Planning Commission and Board of Supervisors.
