Groundwater Sustainability Plan

 

The Sonoma Valley Groundwater Sustainability Agency (GSA) is required by state law, the Sustainable Groundwater Management Act (SGMA), to develop a Groundwater Sustainability Plan (GSP) by January 31, 2022.  The goal of the GSP is to establish a standard for sustainability of groundwater management and use, and to determine how the basin will achieve this standard by 2042.

A Board Meeting and Public Hearing will be held on Monday, December 6, 4:00 p.m. via Zoom for the GSA Board of Directors to consider adoption of the GSP. Public Hearing information is available here.
