The Water Resources Unit is comprised of 2 teams:

Flood Management Team

The Flood Management team is responsible for providing all floodplain administration duties within the unincorporated areas of San Joaquin County. They process various permits; coordinate the improvement and maintenance of the area’s flood control system; provide engineering and technical support to the Channel Maintenance Team; and oversee the development and maintenance of technical and engineering services to various agencies and the public in the administration and investigation of projects for improved flood protection and monitoring floodplain management. Flood Management also coordinates the County’s Storm Water Pollution Prevention Program, and they develop and administer programs to achieve compliance with National Pollutant Discharge Elimination System (NPDES) regulations.


Water Resources Team

The Water Resources team engages in regional, long-range planning for County-wide water issues, development of water rights and new surface water supply, groundwater management, monitoring of groundwater resources, and defending water supply and quality for future water resource sustainability in San Joaquin County and the Sacramento-San Joaquin River Delta.
In coordination with other local and regional agencies, they protect and defend the County’s position on water issues in regional, State, and Federal activities that impact water users and the environment within the County. Water Resources coordinates efforts by multiple committees and authorities for compliance with Sustainable Groundwater Management Act requirements including development and implementation of Groundwater Sustainability Plans for San Joaquin County area groundwater subbasins.
Established County water supply objectives are pursued through activities that include strategic planning and project implementation which address groundwater overdraft. Other activities include water right development on the Mokelumne River.
