Puget Sound NEP stormwater strategic initiative grants

Stormwater washes pollutants into aquatic ecosystems degrading water quality, impacting aquatic life, and threatening human health.

In 1987, the U.S. Congress established the National Estuary Program (NEP). The NEP is a non-regulatory program led by the Environmental Protection Agency (EPA) that identifies estuaries of significance and provides funding to protect and restore the water quality and ecological integrity of the estuary.

One component of NEP funding in the Puget Sound is the Stormwater Strategic Initiative, led by Ecology. EPA coordinates with the Puget Sound Partnership and Ecology to fund projects that help prevent stormwater pollution and protect the estuary. Ecology leads an advisory team to develop an annual Investment Plan that guides the funding priorities for the year.

Visit the Puget Sound  NEP website to learn more about the program, review the Investment Plan, or apply for funding.
