Low Impact Development (LID) is a site design strategy that maintains or replicates predevelopment hydrology through runoff source control by reducing and disconnecting impervious areas, lengthening flow path and runoff time, and protecting sensitive features including: riparian buffers, wetlands, steep slopes and flood plains.
