As stormwater moves through the landscape it captures and carries trash, bacteria, heavy metals, and other pollutants from the urban environment. These pollutants degrade the quality of receiving waters and threaten public health. Stormwater can also cause erosion and flooding, damaging wildlife habitat, property, and infrastructure.
Green infrastructure practices offer flexible solutions for managing stormwater runoff and protecting public health and water quality. Green infrastructure works by incorporating both the natural environment and engineered systems to protect, restore, or mimic the natural water cycle.
This collection of case studies explores the efforts of five CWSRF assistance recipients to monitor or model the environmental benefits of green infrastructure practices.You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.
