About the Urban Runoff

Our community – health, economy, way of life – depends on clean water. Polluted runoff threatens the health of Maine’s lakes, streams, rivers and bays. Runoff happens after any rain storm, and in Maine we see a lot of runoff in the springtime when the snow melts.
Since 2012, we’ve brought a different kind of Urban Runoff to Southern Maine! Runners and walkers will hit the streets and trails in Portland for the annual Urban Runoff 5K race and walk to raise awareness of water pollution and raise money to support clean water education in greater Portland and Saco areas.
The date of the Urban Runoff was chosen to coincide with Earth Day and spring’s “first flush” when rain and melted snow wash pollution into our waterways.
The race is followed by the City of Portland’s Green Neighbor Family Fest, where families and community members enjoy hands-on activities about water, live entertainment, and have an all-around good time!
Join us – help preserve our communities, health, and Maine way of life by keeping our water clean!
