GSA Withdrawals, Modifications, and Opt Out Notices

The table below is a compilation of local agencies and GSAs that have either withdrawn or modified a posted GSA formation notice or opted out of the role as a presumed or exclusive GSA. SGMA outlines a process for local agencies to follow when deciding to become a GSA, and also provides requirements that must be followed if a local agency decides to opt out of its existing or presumed GSA role.

The following is a list of local agencies or GSAs that have decided to do one of the following:

  • Opt out of being the exclusive groundwater management agency within its statutory boundaries. (Water Code §10723(c))
  • Withdraw or modify a posted notice in order to resolve the jurisdictional overlap that resulted when two or more local agencies decided to become separate GSAs within the same area of a basin. (Water Code §10723.8(c))
  • Withdraw or modify a posted notice to correct GSA boundaries formed outside of a service area. (Water Code §10723.8(d))
  • Completely withdraw from being a GSA in a basin. (Water Code §10723.8(e))
  • As a county, withdraw from being the presumed GSA for an area of a basin that is not within the management area of another GSA-eligible local agency. (Water Code §10724)
