About the Sustainable Groundwater Management Act (SGMA)
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.
Are you in an affected basin? While not definitive, the map below can help you determine if you are in one of the three basins. (More detailed maps will be prepared by the GSAs.)
- Petaluma Valley
- Santa Rosa Plain
- Sonoma Valley
What’s Happening in Sonoma County?
In Sonoma County, the State has designated three of the county’s 14 basins and sub-basins as medium-priority: Santa Rosa Plain, Sonoma Valley, and Petaluma. These three basins are required to comply with the Act.
The first step in implementing the new law is to develop Groundwater Sustainability Agencies (GSAs). In March 2015, the Sonoma County Board of Supervisors asked staff to reach out collaboratively to GSA-eligible agencies and to solicit input from farmers, well-owners, economically disadvantaged communities, businesses, environmental groups and other interested stakeholders.
As a follow-up to Board direction, a facilitator conducted a stakeholder assessment and issued a report in September 2015. Working groups comprised of staff from the agencies that are eligible to serve as GSAs in the three basins have been meeting since 2015 to develop recommendations for forming GSAs. Public meetings were held in Fall 2015 and Summer 2016 to inform people about SGMA and to present GSA formation options. The boards and councils of the GSA-eligible agencies have heard presentations and received public comment on staff recommendations.
With the deadline rapidly approaching for GSA formation (June 30, 2017), a final round of community meetings will be held on March 21 (Petaluma Valley), March 27 (Sonoma Valley) and April 3 (Santa Rosa Plain).
The boards and councils of GSA-eligible agencies will be considering the legal agreements for forming GSAs in April and May. A public hearing will be held in each basin in May or June.
