The Napa County Groundwater Sustainability Agency oversees Groundwater Sustainability in the County. The Agency is also in charge of creating and carrying out a Groundwater Sustainability Plan (GSP) for the Napa Valley Subbasin. The Groundwater Sustainability Plan Advisory Committee (GSPAC) helped the Agency create the GSP.

The GSP includes policies and recommendations for taking care of and protecting groundwater within the Subbasin for the long term. The GSPAC submitted a draft GSP for the Agency to review on November 19, 2021.

The Napa County Groundwater Sustainability Agency will meet on January 11, 2022 to consider adoption of the GSP for the Napa Valley Subbasin.  Visit the 1/11 meeting page for more information, agenda, and instructions for virtual or in-person participation.
