Storm Water Management

Font Size: + -

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.

MS4 Part 2 Permit Application

MS4 Permit TMDL Application

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:

Public education and outreach
Public participation and involvement
Illicit discharge detection and elimination
Construction site storm water runoff control
Post-construction storm water management
Pollution prevention/good housekeeping for municipal operations

Flooding

Floods and flash floods are a real risk for homeowners, especially those who live in floodplains. It’s important property owners consider flood insurance.
