State Groundwater Management May Require Metered Wells, Additional Fees

The lengthy, multifaceted work of the Sonoma Valley Groundwater Sustainability Agency reached a benchmark in December 2021 when its board approved a Groundwater Sustainability Plan (GSP) and sent it off to the state for review and potential approval. The plan, including references and appendices, came in at a hefty 1,285 pages, though attentive readers can get the gist in the 28-page executive summary. The final plan is online at, or available in hard copy at the Sonoma Valley Regional Library, 755 W. Napa St., Sonoma.

Probably the most notable part of the plan is the section dealing with potential groundwater user fees and permits — necessary steps to assure the plan is viable and effective.
