Impact/Purpose:
To inform the public.
Description:
This project examines porous pavement systems in a newly constructed parking lot next to Building 205 at the Edison Environmental Center. Porous pavement systems are one means of promoting environmental sustainability through stormwater runoff reduction. This project examines three different porous systems: porous asphalt, porous concrete, and permeable interlocking concrete paving stones. ORD's National Risk Management Research Laboratory is leading the evaluation of the water quality of rainfall and runoff after filtration through a porous pavement system. This evaluation will monitor other possible benefits of porous pavements such as urban heat island reduction, and runoff reduction. This project will track the amount of routine maintenance for porous pavement compared to conventional surfaces in parking lots. The runoff moves through several layers of bedding after it passes the porous surfaces and some pollutants may be removed as the water moves through the underlying materials. This study monitors water quality and flow with a combination of traditional measures and state-of-the-art in-situ instrumentation. It is imperative to acquire long-term data sets in order to make recommendations concerning maintenance schedules for the porous treatments, the possibility of urban heat island reduction via porous pavement, and to assess the durability of these systems. The lifetime of the new lot is expected to be between 10 and 20 years.
