About South San Joaquin GSA
The Cities of Escalon and Ripon and the South San Joaquin Irrigation District have formed a partnership to manage groundwater resources in the areas we serve. The three agencies have formed a separate legal entity called the South San Joaquin Groundwater Sustainability Agency (South San Joaquin GSA). Additionally, the South San Joaquin GSA works closely with other agencies throughout the Eastern San Joaquin Groundwater Basin including portions of Calaveras and Stanislaus Counties.
Like many public agencies, the South San Joaquin GSA is governed by a Board of Directors and is subject to transparency laws and regulations such as the Open Meeting Act (Brown Act) and the Fair Political Practices Commission rules on conflicts of interest.
