Stormwater Management

Stormwater is water that comes from rain or melting snow. This runoff can flow over land or impervious surfaces, such as building rooftops, paved streets and parking lots, and does not soak into the ground. As the runoff flows, it can pick up various pollutants, including trash, chemicals, oils and dirt/sediment that can harm our streams and lakes. To help protect these waterbodies, state and federal rules and regulations have been established to help manage stormwater.

Storm Water Pollution Prevention Program (SWPPP)

In 1987, amendments to the Clean Water Act were put into effect with a comprehensive national program to address pollutants in stormwater runoff. The program covers construction sites, industrial activities and municipal storm sewer systems.

This program resulted in stormwater regulations for the City of St. Louis Park as part of the National Pollutant Discharge Elimination System (NPDES) permit program. The U.S. Environmental Protection Agency (EPA) delegated permitting authority for Minnesota's NPDES program to the Minnesota Pollution Control Agency (MPCA), which developed a general permit that authorizes the city to discharge stormwater.

The City of St. Louis Park’s SWPPP was created to satisfy the requirements of the MPCA’s general permit and serve the city by providing a framework of programs and practices to control stormwater runoff from the city's jurisdiction.

The documents listed below were created to meet the requirements of the MPCA’s permit:

National Pollutant Discharge Elimination System (NPDES) Permit Program

The NPDES stormwater program regulates some stormwater discharges from three potential sources: municipal separate storm sewer systems (MS4s), construction activities and industrial activities. NPDES permits maybe required before operators of these systems can discharge stormwater. These permits aim to help prevent stormwater from carrying harmful pollutants into surface waters. Additional NPDES information can be found at the EPA's NPDES Stormwater ProgramMinnesota Pollution Control Agency's stormwater, and  Minnesota Pollution Control Agency's MS4 webpages.

Adopt-a-Storm-Drain program

Help us protect our lakes, streams and wetlands by adopting a storm drain and keeping it clear of leaves, trash and other debris. The simple act of sweeping up around a storm drain helps protect local lakes and rivers by preventing pollution from entering our shared waterways.

To adopt a storm drain, visit Simply create an account with your name and address to claim your storm drain. Once you’ve signed up, Adopt-a-Storm-Drain will send you tips on how to clean up safely.

With more than 300,000 storm drains in the metro area, everyone’s help is important in making an impact! Learn more on Clean Water Minnesota's website.
