Mid-Kaweah GSA Board of Directors

The Mid-Kaweah GSA was established on Sept. 14, 2015, through execution of the Mid-Kaweah Groundwater Subbasin Joint Powers Authority (JPA) between the City of Visalia, the City of Tulare (including its Board of Public Utilities Commissioners), and Tulare Irrigation District. The agency is led by a six-member Board of Directors comprised of two representatives each of the three local public agencies (California Water Code §10721(n)) accountable for development and implementation of a Groundwater Sustainability Plan pursuant to the Sustainable Groundwater Management Act of 2014.  As required by the JPA, each director is a publicly elected officer of the founding agency and is appointed to serve by their respective legislative body.
