Duluth Residential Stormwater Reduction Demonstration Project for Lake Superior Tributaries

We used paired 2?block street sections in the Amity Creek watershed (Duluth, MN) to demonstrate the effectiveness of homeowner BMPs to reduce residential stormwater flow to storm sewers in an older neighborhood in a cold climate on clay and bedrock geology. Runoff from each street was measured before and after installation of stormwater BMPs. In addition, the knowledge, attitudes, and practices of residents were measured before and after BMP installation. BMPs were installed on properties of willing residents of one street (treatment). Most residents (22 of 25 properties) willingly participated. 250 trees and shrubs were planted; 22 rain barrels were installed; 5 rain gardens"
