Pervious Pavement

Pervious surfaces allow stormwater, that would normally run off into a stormwater drain, to seep into the ground. Pervious concrete is instrumental in recharging groundwater, reducing stormwater runoff, and meeting U.S. environmental Protection Agency (EPA) stormwater regulations. In fact, the use of pervious concrete is among the Best Management Practices (BMPs) recommended by the EPA– and by other agencies and geotechnical engineers across the country– for the management of stormwater runoff on a regional and local basis. This pavement technology creates more efficient land use by eliminating the need for retention ponds, swales, and other stormwater management devices. In doing so, pervious concrete has the ability to lower overall project costs on a first-cost basis.  (from perviouspavement.org)
