Rate and Fee Study

The Sustainable Groundwater Management Act (SGMA) is the 2014 law requiring local Groundwater Sustainability Agencies (GSAs) to form in California’s high and medium priority groundwater basins and requiring GSAs to develop and implement Groundwater Sustainability Plans (GSPs).

The Sonoma Valley  Groundwater Sustainable Agency (GSA) is a public agency formed to sustainably manage groundwater in the Sonoma Valley groundwater basin. The agency was formed in June 2017 and has a Board of Directors, an Advisory Committee and an administrator.

The Board unanimously approved the GSP for the basin in December 2021. The GSP is required to be submitted as part of the SGMA for the purpose of assessing the conditions of the groundwater basin, analyzing the basin’s sustainability over a 50-year period, and identifying projects and actions needed to ensure the basin is sustainable by 2042.

A fee study is underway to determine how to pay for the first five years of implementing the GSP.


Community Meetings

The Sonoma Valley Groundwater Sustainability Agency held virtual community meetings for the Rate and Fee Study.

The purpose of the meetings was to briefly describe Sustainable Groundwater Management Act (SGMA), the Groundwater Sustainability Plan findings, the need for funding and the proposed fee options and to receive community feedback.

What’s the Fee Study Timeline?

In fall 2021, the fee consultants, SCI Consulting and Larry Walker Associates, gathered data and looked at other GSAs across state for funding ideas and options. In January and February, the fee consultants met with the Board and Advisory Committee.

Public meetings will be held in March and May, along with further meetings with the Board and Advisory Committee where the options will be narrowed and refined. It is anticipated that a funding plan will be identified and possibly adopted in May or June.
