Erosion Control at Construction Sites: The Science-Policy Gap

摘要

To test the effectiveness of Michigan's soil erosion control law, 30 construction sites were evaluated in the east-central part of the state. The analytical framework lumped nine best management practies (BMPs) most closely related to the law into three categories: slope stabilization, soil stabilization, and water management. All sites were in the land clearing or foundation/framing stage construction and were evaluated within 2 days after a rainfall event. Only four of the sites performed above the mean of the scoring sclae, with the categorical scoring of BMPs indicating the worst performance for slope stabilization measures.
