Early Results Show Runoff Reduction
Last summer, the North Carolina Coastal Federation (NCCF) commissioned a study of its projects in Wrightsville Beach designed to keep contaminated stormwater from draining into coastal waterways. The full study has yet to appear, but some initial findings are proving the worth of the Best Management Practices (BMPs) that were employed, including rain gardens, pervious surfaces and infiltration chambers. One outfall pipe measured 99 percent less discharge of fecal coliform bacteria after retrofitting—discharge that had previously been flowing into the Banks Channel.
“This is the beginning of the big
effort to push this technology out into the world,” said Tracy Skrabal,
southeast regional manager for the NCCF. “Wrightsville Beach is going
to be at the forefront of these innovative techniques.” In addition to
marking their projects with a plaque, Skrabal plans to give a tour to
representatives from the American Society of Civil Engineers and the
state Department of Transportation, organizations which have shown
interest in implementing some of these techniques.
