What is Stormwater Runoff?
Stormwater runoff occurs when precipitation from rain flows over the ground. Impervious surfaces like driveways, sidewalks, and streets prevent stormwater from naturally soaking into the ground.
Why is Runoff a Problem?
Stormwater can pick up debris, chemicals, dirt and pollutants that likely will flow into a storm sewer system or directly to the body of water. Anything that enters a storm sewer system is discharged, untreated, into the water bodies we use for swimming, fishing, and drinking water.
