Mission Creek Subbasin SGMA Alternative Plan 

On December 29, 2016, the Management Committee submitted the 2013 Mission Creek-Garnet Hill Water Management Plan along with a Bridge document to the California Department of Water Resources (DWR) for review and evaluation as an Alternative to a Groundwater Sustainability Plan. DWR reviewed the Alternative Plan, and on July 17, 2019, determined the Alternative Plan met the requirements of SGMA and approved the plan.  DWR informed DWA, CVWD, and MSWD that they would be required to assess and update the Alternative Plan every five years, with the first plan update due to DWR by January 1, 2022. To view the Alternative Plan for the Mission Creek Subbasin, visit DWR’s SGMA portal.
