3M Educational SignThese wetlands were created to help filter stormwater runoff and provide habitat for wildlife.  Out of concern for the health and welfare of local streams, flora, and fauna, seventeen agency partners came together to restore this area and create the wetlands. The wetland cells treat stormwater runoff from approximately 140 acres of urban watershed and can store and filter an estimated 10,000,000 gallons of runoff. The old sewer treatment pumphouse was repurposed into a viewing platform with picnic tables and a green roof. Visitors will enjoy walking the wetland trail to read the wetland educational signs and observe the wildlife.  In fact, e-bird.org the 3M Wetlands listed as a world “hot spot” for bird sightings.

Twenty-four interpretive signs about the wetlands and the adjacent MKT Trail are distributed along the wetland trail. Each sign has a QR code that trail users can scan with their smart phones and hear an audio version of the sign information. The audio version is also available on-line for each of the 24 educational signs.
