Frequently Asked Questions

Stormwater runoff occurs when rain or snowmelt flows over the ground. Impervious surfaces like driveways, sidewalks, and streets prevent stormwater from soaking into the ground.

As stormwater flows over driveways, lawns, streets, and sidewalks it picks up debris, chemicals, dirt and other pollutants. Stormwater can flow into a storm sewer system or directly into a lake, stream, river or wetland. Anything that enters a storm sewer system is discharged untreated into the water bodies we use for swimming, fishing, and providing drinking water. Polluted runoff is the nation’s greatest threat to clean water.

By practicing healthy household habits, homeowners can keep common pollutants like pesticides, pet waste, grass clippings, and automotive fluids off the ground and out of stormwater. Adopt these healthy household habits and help protect our lakes, streams, rivers, and wetlands. Remember to share these habits with your neighbors!

The National Pollutant Discharge Elimination System Phase II program for the Clean Water Act mandated that all urbanized areas create a regulatory mechanism to control non-point source discharges into the nation’s waterways. Ashland passed its Stormwater Management Bylaw at 2006 Annual Town Meeting to protect the environment through the control of stormwater discharges.
