Storm Water Management

Storm water run-off is the rain and melting snow that flows off streets, rooftops, lawns and farmland. The flowing water can carry salt, sand, soil, pesticides, fertilizers, leaves, grass clippings, oil, litter and many other pollutants.

In urban areas, much of the surface is covered by buildings and pavement which do not allow water to soak into the ground. Instead, storm sewers collect this run-off and transport it to nearby waters.

Storm sewers collect run-off mostly through a network of pipes often located beneath streets and parking lots, but occasionally they are located in backyards in storm water retention ponds and ditches. The storm drainage system allows Shakopee to manage its run-off to prevent flooding, as well as protect water resources.

Storm Water Pollution Prevention Program

In an effort to protect our water resources, the city has a federal National Pollutant Discharge Elimination System (NPDES) storm water permit, administered by the Minnesota Pollution Control Agency.

The permit requires the City, as the owner of a comprehensive storm sewer system, to develop a Storm Water Pollution Prevention Program (SWPPP) [PDF]. The goal of the SWPPP is to reduce the discharge of pollutants from our storm sewer system.

The program has six goals:

  1. Public education and outreach
  2. Public participation and involvement
  3. Illicit discharge detection and elimination
  4. Construction site runoff control
  5. Post-construction storm water management
  6. Pollution prevention/good housekeeping
