According to the EPA, "This report provides information to cities, counties, states, private-sector developers and others on the costs and benefits of using Low Impact Development (LID) strategies and practices to help protectand restore water quality. LID practices are innovative practices that manage stormwater close to its source by mimicing a site's predevelopment hydrology and use design techniques that infiltrate, evapotranspirate, and reuse runoff. LID practices are increasingly being used by communities across the country to help protect and restore water quality. This report provides information on the cost savings and benefits that can be achieved by implementing LID practices versus conventional stormwater practices."
