Project Summary

Task 4 constructed raingardens at strategic locations within the sub watershed and project area providing water quality benefit to the Minnesota River where residents had an expressed interest and a commitment to maintenance.

There were 16 raingardens installed as part of Task 4. Cumulatively they capture over 1.2 million gallons of runoff, 2,000 pounds of solids, and 5 pounds of phosphorus on an annual basis that would otherwise flow into the Minnesota River.
