What is stormwater runoff?

Stormwater is the water that runs off of the land surface when it rains or snow melts. It enters the Town's storm drain system and flows directly to local lakes, streams and wetlands. Stormwater runoff from undeveloped land is typically low since most rain or snow melt infiltrates into the ground or is lost to evaporation. Additional runoff from developed areas is created from impervious surfaces like streets, parking lots, and rooftops that prevent stormwater from naturally soaking into the ground.
