Stormwater Management

About Stormwater Runoff


Stormwater runoff is the water from rain and snow melt that flows across land and does not soak into the ground. As runoff flows over impervious surfaces (streets, parking lots and rooftops), it accumulates sediments, debris, oil, pet waste, fertilizers or other pollutants and is carried into nearby rivers, streams, lakes, ponds and wetlands. The runoff can significantly degrade water quality and aquatic habitat. Stormwater runoff also may increase flooding and erosion.

Stormwater Management


Stormwater is managed through a combination of engineering, construction, maintenance and public outreach to address the quality and quantity of runoff. The runoff in Gardner is directed to lakes and streams through a Municipal Separate Storm Sewer System (MS4). The City is authorized to discharge stormwater through the Phase II National Pollutant Discharge Elimination System (NPDES) General Permit for Small MS4s (PDF).
