Mimics a site's predevelopment hydrology through design techniques that infiltrate, filter, store, evaporate, and detain runoff close to its source. Emphasizes cost-effective strategies at the lot level An approach to land development that uses various land planning, design and construction practices.
3
These include basic design features such as: reducing the use of pipes, ponds, curbs and gutters; maintaining recharge areas, buffer zones, and drainage courses; using infiltration swales, grading strategies, and open drainage systems; reducing impervious surfaces and disconnecting those that must be used; and conserving open space.

5
Almost all components of the urban, suburban, and residential environment have the potential to incorporate LID. open space, rooftops, streetscapes, parking lots, sidewalks, and medians. LID is a versatile approach that can be applied equally well to new development, urban retrofits, and redevelopment/revitalization projects.
