Groundwater Sustainability Agencies in Santa Barbara County

In Santa Barbara County, basins that are subject to the Sustainable Groundwater Management Act (SGMA) include all medium and high priority basins as defined by the State Department of Water Resources (DWR) that have not previously been adjudicated. Under SGMA, these basins are required to form a Groundwater Sustainability Agency (GSA) by June 2017, and once approved by DWR may begin the process of drafting Groundwater Sustainability Plans (GSPs). 


On April 5, 2016 the County Board of Supervisors accepted Proposition 1, Sustainable Groundwater Planning Grant funding monies in the amount of $249,240 from DWR for GSA planning in the Cuyama Valley and San Antonio Creek basins. View the grant agreement work plan.
