Sustainability Plan

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

MGA member agency staff, with support from the Regional Water Management Foundation staff and technical and facilitation consultants and sustained public input from the GSP Advisory Committee and Basin stakeholders, prepared the draft GSP. The MGA Board of Directors accepted the draft GSP at its publicly noticed July 18, 2019 board meeting and opened a public comment period that ran 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 staff in the MGA’s response to comments. The Comment Committee reviewed all comments, discussed revisions to the GSP with staff, and recommended revisions to improve the GSP’s content and clarity. The Comment Committee then worked with MGA staff to oversee preparation of individualized letters to address each comment received on the draft GSP. The MGA’s responses to comments received are compiled in Responses and Comments Received.  (The comments are included at the end of this compiled document.)

MGA staff also prepared a GSP comparison document to catalog the changes made in response to comments received. This comparison shows text edits and strikeouts made between the July 2019 draft GSP and the November 2019 GSP.  

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: 

The DWR Public Comment Period on the Basin GSP is now closed. Information on the Basin GSP and comments received by DWR can be found on the SGMA Portal.
