2. 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.

4. Bioretention/Rain Gardens Rainfall harvesting Permeable Pavement Bioswales Green roofs Stormwater wetlands Tree box planters

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.
