NEW -  Santa Cruz Mid-County Basin Water Year 2023 Annual Report, submitted to the Department of Water Resources March 28, 2024

Groundwater Sustainability Plan (GSP)

Under the Sustainable Groundwater Management Act (SGMA), one of the key responsiblitites of the Santa Cruz Mid-County Groundwater Agency (MGA) was to develop, adopt, and submit to the Department of Water Resources (DWR) a Groundwater Sustainability Plan for the Santa Cruz Mid-County Groundwater Basin (Basin).  DWR had classified the Basin as a high-priority groundwater basin in critical overdraft due to the ongoing threat of further seawater intrusion into Basin groundwater supplies. As a result, the Basin’s GSP was due to DWR by January 31, 2020.

Development of the Draft GSP

A Draft GSP was prepared by MGA member agency staff with support from Regional Water Management Foundation staff, technical and facilitation consultants, and sustained public input from the GSP Advisory Committee and Basin stakeholders. The MGA Board of Directors accepted the Draft GSP at its publicly-noticed meeting on July 18, 2019, and opened a public comment period from July 18, 2019 to September 19, 2019. The MGA received more than 170 comments on the Draft GSP from 23 commenters. Comments were received from state and federal resource agencies, non-governmental organizations, and members of the public.

The MGA Board of Directors established a temporary Board committee to direct the MGA’s response to the comments. The Comment Committee reviewed all the comments, discussed revisions to the GSP with staff, and recommended revisions to improve the GSP’s content and clarity. The Comment Committee worked with MGA staff to oversee preparation of individualized letters to address each comment received. The comments and responses were compiled (Responses and Comments Received), and a comparison document was created to catalog the changes made in response to the comments received. 

Adoption of the GSP and Submission to DWR

The MGA Board of Directors unanimously adopted the final GSP after a public hearing on November 21, 2019.  The adopted GSP was submitted to DWR for approval on January 30, 2020.  On February 19, 2020, DWR posted the Basin GSP at the following link: https://sgma.water.ca.gov/portal/gsp/all. 

Information on the Basin GSP and comments received by DWR can be found on the SGMA Portal. The GSP submitted to DWR is provided below, both as a single document and by individual sections and appendices.
