Shooting down excuses to permeable pavementJune 30th, 2012 by cdunagan
Lisa Stiffler of Sightline Institute does an excellent job addressing common objections to permeable pavement in her latest discussion about stormwater solutions. See Sightline’s website.
I’ve heard the excuses from contractors worried about the use and maintenance of new paving materials. Lisa did some research and tells us that when the concerns are valid, there may be ways to work around the problems.
The fears she allays, including sources for more information:
- Permeable pavement will clog and lose its porousness.
- Holes in permeable pavement make it weaker.
- Permeable pavement won’t work on high-speed, high-volume roads such as highways.
- Permeable pavement won’t work on sloped sites.
- Permeable pavement will result in groundwater contamination.
- Permeable pavement is prohibitively expensive.
- Permeable pavement is more prone to rutting, breaking apart, or otherwise failing.
The latest post is part of Lisa’s ongoing discussion called “Stormwater Solutions: Curbing Toxic Runoff.”
