Description
The California State Water Resources Control Board administers this program using U.S. EPA funding under section 319 of the Clean Water Act, with possible section 604(b) funding for planning. The 2027 cycle supports projects that improve impaired waters, protect assessed high-quality waters, and restore fire-damaged landscapes. Projects must address Regional Water Board priorities for specific watersheds and pollutants.
Supported work includes livestock fencing and off-stream watering, rural and forest road erosion control, stream and floodplain restoration, agricultural nutrient and pesticide management, irrigation improvements, and manure management. Planning grants support nine-element watershed-based plans or preparation for implementation, including site selection, management practice selection, and design. Most funding targets impaired waters and Total Maximum Daily Load implementation.
