Low Impact Development

An approach to land development or re-development, low impact development (LID) seeks to manage stormwater in ways that restore the natural water cycle by keeping water as close to its source as possible, thus treating stormwater as a resource instead of a waste product. LID approaches include reducing impervious cover, protecting and conserving critical open spaces and wetlands, the incorporation of green infrastructure techniques like rain gardens, green roofs, tree pits, and permeable pavement, into developments, these allow stormwater to be soaked into the ground, where it is filtered naturally and replenishes groundwater levels.
