About this opportunity

The program primarily funds implementation projects but occasionally offers grants for planning projects. Examples of projects include livestock fencing to reduce sediment and nutrient discharges, agricultural best management practices to reduce pesticide and nutrient discharges, dredging contaminated sediment from pesticide-impaired waters, habitat restoration such as installation of large woody debris and riparian revegetation, and rural road inventories and repairs to reduce sedimentation and erosion. Most awards go to projects that improve impaired waters, but a small amount of funding goes to projects that protect high-quality waters, or that address a nonpoint source pollution problem created by a wildfire.

Funding geography: Projects must address a program preference, which is a specific watershed or waterbody and pollutant combination that is identified by the Regional Water Quality Control Board. Program preferences are listed in the grant guidelines.

Funding instrument: Grant. Issuing jurisdiction: California. This is not a geographic eligibility determination.
