Stormwater commonly refers to runoff from rain, snow and ice melt. In the Township’s natural settings, stormwater slowly soaks into the ground surface or flows overland into adjacent streams. This process relies on an abundance of pervious surfaces such as grasslands, farmland, lawns, or other natural landscapes. In Cranberry Township, along with all other areas of the state, these natural surfaces are often replaced with impervious or hard surfaces such as streets, sidewalks, parking lots, homes or other similar structures. The result of an urbanized region is the reduced amount of natural area available to absorb stormwater. With an increase in impervious or hard surfaces, a larger amount of stormwater ends up flowing, at a swift rate, over these surfaces where it tends to collect chemicals and debris along the way. If not properly controlled, stormwater can overwhelm streams and embankments and cause major flooding in the Township, along with soil erosion and water pollution.
