Green Streets for Blue Waters - Task 1

Task 1

Multi-Property Bioswale

Project Summary

An existing turf grass drainage swale was restored with native landscaping and soil amendments to encourage storm water infiltration, improve pollutant removal, and decrease mowing, watering and other turf grass maintenance requirements.

The bioswale filters stormwater from 44 acres, capturing 97% of the runoff (446,500 gallons), removing 713 pounds of solids and 2.5 pounds of phosphorous that would otherwise flow into the Minnesota River.

The bioswale is well established with many native grasses and flowers. It is best viewed from the pedestrian path connecting E 105th St Circle to E 104th St.
