Low-impact Development

Low-impact development (LID) is a term used in Canada and the United States to describe a land planning and engineering design approach to managing stormwater runoff. LID emphasizes conservation and use of on-site natural features to protect water quality. This approach implements engineered small-scale hydrologic controls to replicate the pre-development hydrologic regime of watersheds through infiltrating, filtering, storing, evaporating, and detaining runoff close to its source.

LID is similar to sustainable urban drainage systems (SUDS), a term used in the United Kingdom, water-sensitive urban design (WSUD), a term used in Australia, natural drainage systems a term used in Seattle, Washington and "Onsite Stormwater Management", a term used by the Washington State Department of Ecology.

Famous quotes containing the word development:

    Creativity seems to emerge from multiple experiences, coupled with a well-supported development of personal resources, including a sense of freedom to venture beyond the known.
    Loris Malaguzzi (20th century)
