Advisory Committee

The Sonoma Valley Groundwater Sustainability Agency (GSA) Advisory Committee meets periodically. For information on past and future meetings, view the Meeting Calendar.

The Advisory Committee is comprised of community members with diverse perspectives on beneficial groundwater use, including representatives from agriculture, the environmental community, the business community and rural residential well users. The committee’s purpose is to provide input and recommendations to the Board of Directors on groundwater sustainability plan development, implementation and policies.

Terms are two-years (after initial staggered terms), and interested individuals can apply to participate by contacting the GSA administrator.


The Sonoma Valley Groundwater Sustainability Agency (GSA) board is seeking to fill one Business community interests seat and one At-Large community interests (hydrologist/geologist preference) seat on the Sonoma Valley GSA Advisory Committee.

Sonoma Valley residents interested in groundwater are urged to apply. The Advisory Committee provides input and feedback on policies, programs and projects to the Board of the Sonoma Valley GSA. This agency was formed to meet the requirements of California’s historic Sustainable Groundwater Management Act (SGMA), which went into effect in 2015.

The Sonoma Valley GSA Advisory Committee consists of 12 members, six of which are appointed by the Sonoma Valley GSA board. These seat appointments are intended to complete the January 1, 2023 to December 31, 2024 term, with the option to apply for additional terms.

The Advisory Committee meets on average three times a year for two to three hours. Advisory Committee members should expect to spend several hours reading materials and preparing for meetings. Strong consideration will be given to candidates who have the backing of multiple organizations or individuals within their interest group.

The deadline for submitting applications is 5:00 pm, Friday, January 16, 2023. Click here to download the application.
