Groundwater Sustainability Plan

A Groundwater Sustainability Plan (GSP) is a 20-year plan to ensure the sustainable use of groundwater within a groundwater basin.

The Sonoma Valley Groundwater Sustainability Agency (GSA) is required by state law, the Sustainable Groundwater Management Act (SGMA), to develop a 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.

The Public Review Draft of the Sonoma Valley GSP is available for your review and comments through 5 p.m., October 31.

We look forward to your feedback.
