Storm Water Management

Storm Water Concerns

Several national comprehensive studies have indicated that storm water runoff pollution within highly urbanized areas is a major contributor to water pollution in the United States. As rain falls and storm water runoff collects and travels over urban lands, it picks up and carries pollutants through municipal separate storm sewer systems (MS4s) and ultimately on to streams, lakes, rivers, and other water sources impairing water quality.

Under the authority of the Clean Water Act, the Environmental Protection Agency (EPA) developed a storm water permitting program with the goal of significantly reducing the pollution source. The City of Allen has been designated by the EPA as an urbanized area and therefore must make application to discharge storm water to waters of the United States.
