Stormwater runoff is any precipitation that falls on impervious surfaces and flows into either a storm drain, which eventually leads to a waterway, or directly into a waterway. The problem with runoff is that it collects trash, bacteria, and toxic chemicals and carries it all the way to where it drains into local creeks and streams and, in the Anacostia Watershed, eventually to the Anacostia River. With a watershed that is 70% developed, the Anacostia is impacted by a huge amount of impervious surface; reducing this impact is our biggest challenge.
