Stormwater is falling rain or melting snow that can't be absorbed by pervious surfaces or that flows off impervious surfaces and enters Howard County's stormwater drainage system—eventually flowing to the Chesapeake Bay. Along the way, the runoff picks up pollutants and carries them to local streams and rivers, where they can harm plants and animals and even cause erosion and flooding.
