Stormwater Management & Best Management Practices

Stormwater runoff is generated when precipitation from rainfall and snowmelt flows over top of the land because it is not able to percolate (soak) into the ground. Runoff can occur on land that is compacted or bare (no trees or vegetation) or that is sloped (hills or mountains) or covered by manmade surfaces (impervious surfaces). Impervious surfaces can consist of paved streets, parking lots, building rooftops, decking, driveways etc.  The precipitation that runs off can flow into storm drains (that lead eventually to a stream, river or other body of water), rivers, lakes and eventually the oceans.

Runoff can accumulate debris, chemicals, sediment (soil), excess nutrients (lawn fertilizers or soaps from washing vehicles in your driveway) or other pollutants such as oil and grease, pesticides and herbicides, bacteria or viruses from non-functioning septic systems, combined sewer overflows and pet waste that is not disposed of properly. Stormwater runoff can also lead to erosion, flooding and other environmental and health issues if not properly maintained.

The primary method to control stormwater runoff is the use of best management practices (BMPs). Stormwater BMPs are devices, practices, or methods that are used to manage stormwater runoff. The links below provide information on the types of BMPs that can be used to manage stormwater runoff:
