(PD) - Leaders of Sonoma County’s wine industry on Monday fired a new volley in the protracted, cyclical battle over the expansion of their industry, hosting political appointees and county staff for a “mobile educational workshop” in an effort to inject industry-friendly language into long-delayed land-use policy.

Sonoma County Vintners, an industry trade association, organized the unique public meeting of the county’s Planning Commission, with stops including a recently completed 24-person, dormitory-style farmworker residence near Cloverdale, MacRostie Winery Estate west of Healdsburg and Kendall-Jackson Wine Estate and Gardens north of Santa Rosa.

In Cloverdale, it was housing; at Kendall-Jackson, code enforcement. But the backdrop for the meeting was Permit Sonoma’s move to update an ordinance related to agricultural promotional activities — wine tastings and other events that fuel traffic and other impacts in rural areas.
