Low impact development principles complement, and sometimes replace, traditional stormwater management systems, which historically emphasized moving stormwater off-site with curbs, pipes, ditches and ponds. The Low Impact Development (LID) paradigm, also known as Green Infrastructure (GI) is predicated on capturing, treating and preserving stormwater where it hits the ground. Low impact development (LID) strategies aim to mitigate these adverse impacts. Low impact development (LID) is a development strategy that seeks to manage storm water runoff more effectively by dealing with runoff water on site, rather than trying to channel the water away as quickly as possible. Mitigation measures are expected to mimic the natural timing, flows, and volumes of the ephemeral drainage features that will be altered during development. Recently, the concept of a "sponge city" was proposed by the Chinese government, which includes LID controls at the source, a pipe drainage system . LID may be incorporated into site The overarching goal is to restore the natural ability of an urban site to absorb . Low Impact Development. It includes landscaping and design techniques that attempt to maintain the natural, pre-developed ability of a site to manage rainfall. Low impact development strategies deal with the way a site is designed and graded and deals with strategies such as reducing impervious areas, using permeable pavements, eliminating curbs or allowing stormwater to move through curbs, or installing strategies such as rain gardens and bioswales. Low Impact Development techniques allow Phase II communities to implement effective stormwater management programs while also providing the opportunity to lessen the economic impacts of compliance. through Low Impact Development (LID) Strategies and Practices, December 2007, EPA 841-F-07-006.
