Permeable Parking Lot Project
The US EPA's Permeable Parking Lot project was completed in October 2009 at the EPA Edison Research Facility in Edison, NJ.
The permeable parking lot is made of 3 different surfaces that capture rain and collect the runoff in a basin beneath the parking lot.
The parking lot helps the environment because it reduces storm water volume flowing to receiving waters, improves water quality by removing solids and other environmental contaminants, and helps to reduce urban heat island effects that occur with conventional parking lots. As part of on going research, all of these features will be monitored over time.
