|Surface Infiltration Rates of Permeable Surfaces: Six-Month Update (November 2009 through April 2010) (EPA/600/R-10/083) June 2010
At the end of October 2009, EPA opened a parking lot at the Edison Environmental Center that included three parking rows of permeable pavement. The construction was a cooperative effort among EPA’s Office of Administration and Resources Management, the National Risk Management Research Laboratory, and the facility owner, Region 2. The lot serves as an active parking area for facility staff and visitors and as a research platform.
Key unknowns in the application of the green infrastructure include the long-term performance and the maintenance requirements. The perceived uncertainty in these is a barrier to widespread adoption of the installation of permeable surfaces for stormwater management. EPA recognizes the need for credible long-term performance maintenance data and has begun a long-term monitoring effort on this installation.
This document outlines the methods and results of the surface infiltration monitoring of the permeable parking surfaces during the first six months of operation.
