Surface Water Management
Storm Water Pollution Prevention Program (MS4)
As part of the overall National Pollutant Discharge Elimination System/State Disposal System (NPDES/SDS) permit program, the City is permitted by the Minnesota Pollution Control Agency to discharge storm water to waters of the State under the small Municipal Separate Storm Sewer System (MS4) permit. As part of this permit, the City is required to develop, implement, and enforce a Storm Water Pollution Prevention Program (SWPPP). The SWPPP requires six minimum control measures:
- Public education and outreach
- Public participation and involvement
- Illicit discharge detection and elimination
- Construction site stormwater runoff control
- Post-construction stormwater management
- Pollution prevention/good housekeeping for municipal operations

Rain Gardens Make Sense
The term "rain garden" is still new, but one that is becoming more familiar to citizens and the raingardens themselves more prominent in our cities and individual yards. A rain garden is a shallow depression garden designed to catch and treat stormwater runoff, which is the leading cause of water pollution in the United States. Runoff is created in areas with impervious surfaces such as roads, parking lots, roofs or even compacted soils as rain and snowmelt is unable to soak into the ground thus it "runs off" the surface. This runoff flows to the nearest lake, river, pond, or wetland picking up and carrying with it pollutants on the surfaces such as sediment, nutrients, pet waste and bacteria, oils, and grease.
