Low impact development (LID) rainwater management programs are designed to manage stormwater close to its source by mimicking a site's pre-development hydrology through the use of design techniques that infiltrate, filter, store, evaporate, and detain runoff close to its source. Treatment and potential reuse of rainfall on-site is a key result of such programs, aiming to reduce runoff volume and improve water quality.
