A GSP is the plan outlining how to achieve sustainably managed groundwater that meets the requirements of SGMA. GSAs in high and medium priority groundwater basins are required to submit a GSP to the State. The plan must outline how the GSA will implement, manage and measure specific actions to groundwater achieve sustainability within 20 years. If a GSA already has an existing groundwater management plan that is functionally equivalent to a GSP, they were able to submit it for DWR approval.
In January 2017, the Coachella Valley Water District, Desert Water Agency, Coachella Water Authority, and Indio Water Authority collaboratively submitted the 2010 Coachella Valley Water Management Plan Update, the 2016 SGMA Alternative Groundwater Sustainability Plan Bridge Document for the Indio Subbasin, and other supporting documents as an Alternative Plan to a GSP for the Subbasin, which was subsequently approved by DWR on July 17, 2019.
