Why can stormwater runoff be a problem in the Township?

As stormwater runoff flows over lawns, roadways, parking lots, or land disturbed by construction activities, it accumulates chemicals, oils and grease, debris and litter, heat or other pollutants that contaminate and adversely affect the water quality of our natural waterways. Also, as more impervious cover is constructed or as natural vegetation is cleared and the underlying soil is compacted, more stormwater runoff is generated.

Stormwater runoff pollution can lead to deterioration of the quality of our natural waterways which are used for fishing, swimming, boating, as well as sources of our potable water supply. Increases in stormwater volume can lead to accelerated stream bank erosion and more frequent stream channel flooding which can result in damage to and loss of property as well as premature failure of roadway culverts and bridges.
