Groundwater Sustainability Plan


On March 20, 2018, City Council of the City of Marina formed the City of Marina Groundwater Sustainability Agency ("MGSA"). The MGSA was founded in order to comply with California's Sustainable Groundwater Management Act; the purpose of the MGSA is to protect and preserve the groundwater within the MGSA jurisdiction for today and the future.

The Groundwater Management Area:

The MGSA occupies an area within the City Limits which lies outside the jurisdictional limits of the Marina County Water District("MCWD") GSA. Inside of our jurisdictional area, there is a 180/400-Foot Aquifer Sub basin where seawater intrusion has occurred. Research conducted by a team from Stanford University and the Monterey County Water Resources Agency ("MCWRA") demonstrated that the hydro-geology and groundwater quality distribution in this area is more complex than previously thought. Groundwater resources in this area meet the state's definition for "Potential source of Drinking Water".

Planning for the Future:

In order to protect local groundwater resources and comply with the Sustainable Groundwater Management Act (SGMA), MGSA is developing a locally focused Groundwater Sustainability Plan ("GSP") for its management area. This GSP will identify local hydro-geologic conditions, establish sustainable management criteria to protect the beneficial uses and users of groundwater in the area, and assure sustainable groundwater management in accordance with SGMA. MGSA will coordinate its efforts with the more regional GSP that is currently in the works for the remainder of the 180/400-Foot Sub basin by the SVBGSA.
