Reducing Stormwater Costs through Low Impact Development (LID) Strategies and Practices analyzes 17 case studies of low impact development (LID) projects throughout the United States. The low impact development projects referenced include conservation designs, infiltration practices, runoff storage, runoff conveyance, filtration, and low impact landscaping. The benefits considered within the analysis include environmental benefits (i.e., pollution abatement, protection of downstream water resources, groundwater recharge, water quality improvements, reduced incidence of combined sewer overflows (CSO), habitat improvement), land value and quality of life benefits (i.e., reduced risk of downstream flooding and property damage, increased real estate values, lot yield, improved aesthetics, enhanced public space), and compliance benefits (i.e., regulatory compliance). The analysis also includes a cost comparison of low impact development projects to traditional grey infrastructure projects. The report concludes that low impact development projects significantly reduce costs and improve environmental performance.
