Storm Water Resources

There are approximately 221 bodies of water in Edina that receive storm water.

This includes streams, ponds, lakes and wetlands. The City is reducing impervious areas when feasible guided by the Comprehensive Water Resource Management Plan. During construction projects, water treatment devices are being installed to reduce pollutants leading to water bodies. Streets are swept twice per year.

The City of Edina is not the local government unit for storm water management. Please consult with the Minnehaha Creek Watershed District or Nine Mile Creek Watershed District to see if any permits are required for your project.

Storm Water

storm water is water from rain or melting snow that does not soak into the ground. It flows from rooftops, over paved areas, bare soil, and through sloped lawns. As it flows, the runoff collects and transports a wide range of pollutants. Common pollutants include:

  • Bacteria: From pet and wildlife waste, and failing septic systems
  • Phosphorus: From tree leaves, grass clippings, soil erosion, fertilizer, pet and wildlife waste
  • Sediment: From exposed soil on construction sites, sparse lawns, and unprotected garden beds set close to hard surfaces like streets, sidewalks and driveways
  • Toxins: Oil, paint, cleaners, soaps, etc.
You don't need a heavy rain to send pollutants rushing toward streams, wetlands and lakes. Even if your house is not on a waterfront, storm drains and sewers efficiently convey runoff from your neighborhood to the nearest body of water. Unlike our household wastewater, storm sewers do not carry storm water to wastewater treatment plants.

Rules & Regulations

The Storm Water Rules, or Phase II National Pollutant Discharge Elimination System, were enacted as part of the Clean Water Act and are the next step in the Environmental Protection Agency's (EPA) effort to preserve, protect and improve the nation's water resources from polluted storm water runoff. The Phase II Rules are directed at Municipal Separate Storm Sewer Systems (MS4s) in urbanized areas. MS4s with populations of 100,000 or more were covered under the Phase I Rules.

The City has a Storm Water Pollution Prevention Plan (SWPPP) that was approved by the PCA. The SWPPP provides a plan of action and a series of Best Management Practices that the City will undertake to assist in obtaining these goals. Public education, public participation events and employee training are parts of the City's storm water program.

Porous Pavement

Concrete and asphalt roads, driveways and walkways prevent groundwater from soaking into the ground. When you have the choice, consider alternative materials for walkways, driveways and patios. Avoid paving areas such as patios. Where you need a more solid surface, consider using a "porous pavement" made from interlocking blocks that allow spaces for rainwater to soak into the ground. If you choose to pour concrete or asphalt, keep the paved area as short and narrow as possible.

Riparian Buffers

Riparian buffers are upland areas adjacent to streams, lakes, wetlands or other surface water. Leaving a natural, undisturbed strip of land along water bodies provides a transition zone between the surface water and the human land use upstream. This transition zone is called a riparian buffer, or more simply, a buffer.

Buffers along rivers, streams, lakes and wetlands provide for diffuse of storm water runoff, maintain bank stability, and remove nitrogen, phosphorous, and other pollutants from storm water before it reaches our waterways. Stream buffers are also complex ecosystems that provide habitat and improve the health of the wildlife they shelter, as well as open space for people to enjoy. For riparian buffers to be most beneficial, they must remain undisturbed in their natural state. A healthy buffer of native vegetation is one of the most effective ways to protect our water resources.
