Stormwater

Storm water is any form of precipitation, such as rainfall and snowmelt, which flows across the surface of the ground. Storm water that does not soak into the ground becomes surface runoff, which flows into storm sewers, surface waterways, or receiving streams. The term storm water applies to water that originates from overwatering of landscapes and enters the storm water system. Although a natural part of the water cycle, storm water runoff is also a potential environmental concern. Pollutants can enter surface waters such as lakes, creeks, streams, and other natural waters when they are picked up by the storm water. To the right, runoff flows into a storm water drain.

Oneimage of storm water and land development of the greatest potential contributors to storm water pollution is land development. While essential to the growth of our community and economy, land development can impact the quality of our water by accelerating erosion. If appropriate preventive measures are not taken, those soils can wash into the storm drain system during rain events causing blockage and pollution of our lakes, creeks, and streams. To the left, an impaired silt fence fails to hold in sediments.
