The U.S. Environmental Protection Agency (EPA) estimates stormwater runoff is responsible for 70 percent of all water pollution in lakes, rivers, and creeks. When developers use conventional methods such as impervious surfaces, stormwater is often left uncontrolled. The emergence of low-impact development (LID) and effective stormwater Best Management Practices (BMPs) are changing designers’ perceptions of stormwater from a constraint into an opportunity for natural processes to return.
