Low Impact Development (LID) refers to a land planning and engineering design approach that aims to minimize the impact of built environment on natural hydrologic function. It emphasizes conservation and use of on-site natural features to protect water quality and reduce downstream flooding. LID incorporates principles of green infrastructure, sustainable site design, and building performance to create developments that work in harmony with nature. The focus is on managing stormwater at the source through infiltration, evapotranspiration, and bioretention, rather than relying on traditional end-of-pipe controls. By mimicking natural hydrologic processes, LID helps protect water resources, enhance ecological function, and create more livable communities.
