A Groundwater Sustainability Plan (GSP) is a 20-year plan to ensure the sustainable use of groundwater within a groundwater basin. The Ukiah Valley Basin Groundwater Sustainability Agency (UVBGSA) is required by state law, the Sustainable Groundwater Management Act (SGMA), to develop a GSP by 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 Ukiah Valley Basin GSP is being developed for the Ukiah Valley Basin Groundwater Sustainability Agency (UVBGSA). Larry Walker Associates, Inc. in collaboration with GEI Consultants, University of California Cooperative Extension (UCCE), and SCI Consulting Group (LWA Team) are the consultants selected to development GSP at the direction of the UVBGSA. The UVBGSA Board of Directors acts as the GSP’s overall Project Management Team (PMT) and meet on the second Thursday of month at 1:30 p.m. in the Mendocino County Board of Supervisors Chambers. UVBGSA has convened a Technical Advisory Committee (TAC) to provide input and recommendations on the technical aspects of the GSP development process. Please visit the TAC page for more detials

The GSP development is being funded by a Department of Water Resources (DWR) Proposition 1 grant and the Mendocino County Water Agency is providing grant management for the project.
