The National Municipal Stormwater and Green Infrastructure Program for Municipal Separate Storm Sewer Systems (MS4) aims to recognize high-performing communities that meet and exceed regulatory requirements in a technically effective and financially efficient manner. Led by the Water Environment Federation (WEF), the awards were established in 2015 through a cooperative agreement with the U.S. Environmental Protection Agency (EPA).

Submissions undergo a thorough review by an expert committee and are evaluated in two categories: program management and innovation.  The three highest-scoring programs(s) in Phase I and II within each category will be honored at the 2026 National Stormwater Policy Forum in Washington, DC.

Please contact Lisa Deason, Stormwater Practice Leader, with questions at ldeason@wef.org or by text/call at 706-681-7091.

Award Application Period will Open in Late Summer 2025.
