Retrofitting with Bioretention and a Swale to Treat Bridge Deck Stormwater Runoff

摘要

This final report has been written to satisfy NCDOT research contract 2009-29: Monitoring of Prospective Birdge Deck Runoff BMPs: Bioretention and Bioswale. The research funding was spurred by the passage of Session Law 2008-107, The Current Operations and Capital Improvements Act of 2008, by the North Carolina General Assembly which required research into and installation of stormwater control measures for bridge decks. This study was designed to determine the hydrologic and water quality impacts of purposefully undersized bioretention, a standard bioretention basin, and a swale. The authors wish to thank NCDOT and URS Corporation for their aid throughout the project.
