Sustainability Plan

One of the key responsibilities of the MGA is to develop, adopt, and submit a Groundwater Sustainability Plan (GSP).  Because the Mid-County Groundwater Basin is in critical overdraft, the GSP is due to the Department of Water Resources (DWR) no later than January 31, 2020.

The Draft Groundwater Sustainability Plan (GSP) for the Mid-County Groundwater Basin was presented to the Board of Directors on July 18, 2019. There is an open public comment period that will end at the Public Hearing on September 19, 2019. The final GSP will be brought to the MGA Board in November for approval, after which it will be submitted to DWR. Once DWR has received the GSP, they will open up a 60 day period during which the public can provide comments about the GSP to DWR.

Hardcopies of the Draft GSP can be found at the following public library branches:

Downtown Santa Cruz – 224 Church St

Aptos Branch - 7695 Soquel Drive

Branciforte Branch – 230 Gault Street

La Selva Branch – 316 Estrella Avenue

Live Oak Branch – 2380 Portola Drive
