Stormwater runoff is generated when precipitation from rain and snow flows over land or impervious surfaces and does not percolate into the ground. As the runoff flows over the land or impervious surfaces (paved streets, parking lots, concrete and rooftops), it accumulates debris, chemicals, sediment and other pollutants that adversely affect water quality.
Impervious surfaces do not allow the absorption of rainwater, and include driveways, sidewalks and rooftops. Impervious materials include asphalt, cement, brick and stone.
