Low Impact Development (LID) are practices that simulate the natural environment through the use of infiltration, evapotranspiration, and reuse of stormwater runoff to protect water quality. Examples of LID include practices such as sites with soils conducive to infiltration that can utilize surface or underground infiltration systems. Other examples are sites with shallow depth to groundwater or soils with slow infiltration rates that can utilize green roofs, cisterns for capturing stormwater for reuse in irrigation or grey water, or lined biofiltration facilities.
