The term low-impact development (Canada/US) is used in Canada and the United States to describe a land planning and engineering design approach to managing stormwater runoff. In recent years many states in the US have adopted LID concepts and standards to enhance their approach to reducing the harmful potential for storm water pollution in new ...

Stormwater, also written storm water, is water that originates from precipitation , including heavy rain and meltwater from hail and snow. Stormwater can soak into the soil ( infiltrate ) and become groundwater , be stored on depressed land surface in ponds and puddles , evaporate back into the atmosphere, or contribute to surface runoff .
Low-impact development (LID) is a term used in Canada and the United States to describe a land planning and engineering design approach to manage stormwater runoff as part of green infrastructure. LID emphasizes conservation and use of on-site natural features to protect water quality .
[3] [4] Most municipal storm sewer systems discharge untreated stormwater to streams, rivers, and bays. This excess water can also make its way into people's properties through basement backups and seepage through building wall and floors. Urban runoff can be a major source of urban flooding and water pollution in urban communities worldwide.
