Paso Robles Subbasin Groundwater Sustainability Plan (Revised)

This Groundwater Sustainability Plan (GSP) fulfills the requirements of the Sustainable Groundwater Management Act (SGMA) for the Paso Robles Subbasin of the Salinas Valley Basin. The sustainability goal of this GSP is to sustainably manage the groundwater resources of the Paso Robles Subbasin for long-term community, financial, and environmental benefit of Subbasin users. This GSP outlines the approach to achieve a sustainable groundwater resource free of undesirable results within 20 years, while maintaining the unique cultural, community, and business aspects of the Subbasin. In adopting this GSP, it is the express goal of the GSAs to balance the needs of all groundwater users in the Subbasin, within the sustainable limits of the Subbasin’s resources. The GSP describes the Paso Robles Subbasin, develops quantifiable management objectives that consider the interests of the Subbasin’s beneficial groundwater uses and users, and identifies management actions and conceptual projects that will allow the Subbasin to achieve sustainability by 2040. This GSP covers the entire Paso Robles Subbasin.

The Paso Robles Subbasin GSP has been jointly developed by four Groundwater Sustainability
Agencies (GSAs):

• City of Paso Robles GSA
• Paso Basin – County of San Luis Obispo GSA
• San Miguel Community Services District (CSD) GSA
• Shandon – San Juan GSA

Submitted to the California Department of Water Resources (DWR) in January 2021, the first version of this GSP was reviewed by DWR in January 2022 and determined to be incomplete (DWR, 2022). Corrective actions were provided by DWR for two identified deficiencies; these corrective actions are incorporated into this June 13, 2022 GSP for resubmittal to DWR.
