What it funds

Purpose and description as published on the California Grants Portal.

Purpose

The Clean Water Act Section 319 Grant Program supports projects to reduce and mitigate the effects of nonpoint source pollutants to waters of the state within priority watersheds identified by the Regional Water Quality Control Boards. Projects that improve impaired waters, protect high quality waters, and restore fire-damaged landscapes will be considered along with planning and implementation project proposals.

Description

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.
