Stormwater Management: Terminology

Stormwater runoff occurs when precipitation does not infiltrate soil, but instead, flows over land or through storm drains to streams, rivers, and lakes. This water collects pollutants as it moves over streets, parking lots, driveways, and other surfaces. To reduce pollution, it’s important to manage this stormwater runoff at the home, city, state, and national levels.
