The Napa County Groundwater Sustainability Agency (GSA) unanimously approved and adopted the final Napa Valley Subbasin Groundwater Sustainability Plan (GSP) on January 11, 2022, and the GSP was submitted to the California Department of Water Resources (DWR) on January 31, 2022. The completion of this plan, following an 18-month stakeholder-driven planning process, is a major step forward in the County’s efforts to achieve sustainable groundwater management for the Napa Valley subbasin.
“The approval and adoption of the GSP is a strong endorsement of the public process,” said David Morrison, Director of Planning, Building and Environmental Services. “The final GSP reflects the concerns of a diverse array of stakeholders and I’m confident the adopted plan is the County’s best tool for achieving sustainability and protecting this vital natural resource for all the residents of Napa County.”
The Napa Valley GSP was required to be developed as part of the Sustainable Groundwater Management Act (SGMA) for the purpose of assessing the conditions of the groundwater basin, analyzing the subbasin’s sustainability over a 50-year period, and identifying projects and actions needed to ensure the basin is sustainable by 2042.
Recognizing the importance and urgency of protecting groundwater resources, the County began implementation immediately upon adoption of the GSP. Many activities are ongoing or have been initiated since GSP adoption, including:
