The 23.5acre Renaissance Park on Chattanooga’s North Shore hasbeen designed and constructed on a former industrial site. Anintermittent stream draining over 175 acres of urban watershed cutsthrough the park, contributing to significant non-source pointpollution of the Tennessee River. Enamel frit waste cells left inthe water table by previous owners threatened to leach a range ofcontaminants into the surrounding site and water systems. Buriedwaste was removed and stabilized chemically and geotechnically onsite rather than be exported to landfills. A created wetland systemnow collects and cleans urban runoff generated on site and runoffbrought onto the site via the North Market Street Branch stream,before release into the Tennessee. Finally, unstable and activelyerosive stream and river banks have been stabilized with a uniquevegetative revetment system and the use of fascines andlive-staking, as well as a series of gabion structures and rip-raparmature.
