Sonoma County Sustainable Groundwater

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 is the creation of local Groundwater Sustainability Agencies (GSAs).

Groundwater Sustainability Agency

The Santa Rosa Plain Groundwater Sustainability Agency (GSA) is a newly formed public agency and its purpose is to secure groundwater sustainability for the Santa Rosa Plain Groundwater Basin. The Agency has a GSA Board and an Advisory Committee.

The purpose of the Advisory Committee is to provide input and recommendations to the GSA Board on groundwater sustainability plan development, implementation, and policies. The intent of the committee is to provide community perspective and participation in the Agency. The composition of the Advisory Committee is intended to represent the beneficial uses and users of groundwater identified in the Sustainable Groundwater Management Act.

Applications due by July 31st, 2017

Advisory Committee terms will be two-years, and interested individuals can apply to participate. Please check eligibility requirements.

Preference will be given to candidates with experience and technical expertise with groundwater and its management and to applicants with experience working with diverse community-based groups.

Groundwater Sustainability Plan

The second step required under SGMA will be to develop a new groundwater sustainability plan. The existing Basin Management Plan forms a strong foundation upon which to build and develop the new GSP. This process may include continuing to implement recommended Plan actions, such as those in the Plan’s Stakeholder Involvement and Monitoring & Modeling Components.
