LID comprises comprehensive, engineered site-design strategies and techniques that seek to mitigate the impacts of increased runoff and stormwater pollution by replicating or maintaining the site’s pre-development hydrological and ecological functions. This is achieved as close to the runoff source as possible through the processes of retention, filtration, infiltration and evapotranspiration. These practices can effectively remove nutrients, pathogens and metals from runoff, and they reduce the volume and intensity of stormwater flows. | LID comprises comprehensive, engineered site-design strategies and techniques that seek to mitigate the impacts of increased runoff and stormwater pollution by replicating or maintaining the site’s pre-development hydrological and ecological functions.
