What is stormwater runoff?

Stormwater runoff is water from rainfall, snowmelt, and/or ice melt that flows over ground or impervious surfaces (paved streets, parking lots and rooftops) and does not percolate into the ground. Stormwater runoff may flow directly into natural tributaries, streams, rivers, lakes or other waterways within the Township or it is intercepted and collected by the Township’s municipal separate storm sewer system where it is then discharged at discrete locations (outfalls) into streams, rivers, lakes and other natural waterways.
