Solano Collaborative

In 2016, a series of meetings with a “GSA Advisory Group”, which included representatives from all interested Groundwater Sustainability Agency (GSA)-eligible agencies as well representatives from the agricultural community were held. The agricultural representative groups included: the Solano County Farm Bureau, Solano County Agricultural Advisory Committee, and the Dixon Resource Conservation District and the Solano Resource Conservation District. These meetings were held with the purpose of determining if a single GSA could be formed to comply with the Sustainable Groundwater Management Act (SGMA) and implement a Groundwater Sustainability Plan (GSP). This group worked to develop recommendations for what the GSA(s) would look like and how to best include agricultural representation. The recommendations were released for board and public review in October 2016 and discussed in December 2016 public input meetings. Ultimately, several GSAs were established, including the Solano GSA, City of Vacaville GSA, Sacramento County GSA, Solano Irrigation District GSA, and the Northern Delta GSA. Please contact the GSAs directly to find out about details on upcoming meetings you would like to attend.

Collectively these GSAs are the Solano Subbasin GSA Collaborative (Solano Collaborative):

The purpose of the Solano Collaborative is to work towards development of a single Groundwater Sustainability Plan (GSP) for the Solano Subbasin, to fulfill the requirements of the Sustainable Groundwater Management Act (SGMA). Prior to, or upon completion of the GSP, a Memorandum of Understanding (MOU), or some other legal instrument, will be executed to describe the governance and implementation of the GSP amongst the Collaborative. An MOU might also be needed during development of the GSP for a recommended governance structure and process for resolving issues as the GSP is developed.

What do GSAs do?

Coordination: GSAs need to coordinate with other local and regional agencies in their basin and neighboring basins.

Public Outreach & Stakeholder Engagement: GSAs are required to engage with interested stakeholders during GSP development and implementation.

GSP Development: Every medium and high priority basin is required to develop and implement one or more GSPs. If multiple GSPs are developed for the same basin, a coordination agreement will be required.

Monitoring & Reporting: Monitoring of groundwater levels and water quality is needed to track progress toward meeting the sustainability objectives of the GSP.

GSP Implementation: The GSP for the Solano Subbasin is due by January 31, 2022 and the subbasin should achieve sustainability by 2042.

Enforcement: The GSAs will need to enforce the provisions adopted in its GSP. It is up to the local GSAs, with the input of the local groundwater users and stakeholders, to determine what particular authorities and tools will be used to successfully achieve the GSP objectives.
