About the Sustainable Groundwater Management Act in Sonoma County

In September 2014, Governor Brown signed historic legislation requiring that California’s critical groundwater resources be sustainably managed by local agencies. The Sustainable Groundwater Management Act (SGMA) gives local agencies (cities, counties and water districts) powers to sustainably manage groundwater over the long-term, and requires Groundwater Sustainability Plans (GSPs) be developed for medium- and high-priority groundwater basins.

The first step implementing the new law was the creation of local Groundwater Sustainability Agencies (GSAs). By the state deadline (June 30, 2017), three GSAs were formed in Sonoma County: Santa Rosa PlainSonoma Valley, and Petaluma Valley.
