In December 2011, the Chattanooga City Council voted to authorize a green roof for the City Council Building. The green roof is part of a re-roof project for the building. The LiveRoof® Hybrid Green Roof System from LiveRoof, LLC (Spring Lake, Mich.) will be installed.
Reducing stormwater runoff is a priority for the City of Chattanooga. The tunnels of the City’s combined sanitary sewer and stormwater system lead into below ground caverns that in turn direct the flow to the Moccasin Bend Sewage Treatment Plant. During severe storms, excess runoff overflows and pollutes local creeks and the Tennessee River.
“Green infrastructure has more promise for revitalization of our impaired streams and waters while revitalizing our city than any prior approach,” said David Crockett, Director, Office of Sustainability, City of Chattanooga. “Green roofs are one of the best examples with multiple positive outcomes.”
The LiveRoof system has been proven successful in the Chattanooga area. The Chattanooga Housing Authority installed LiveRoof in June 2011 for the 2,200-square-foot green roof at the Mary Walker Towers. Hamilton County Health Department used LiveRoof for its 1,500-square-foot green roof, completed in December 2011. The Creative Discovery Museum has a 3,800-square-foot LiveRoof green roof, installed in March 2010.
LiveRoof modules feature the Soil Elevator™ and Moisture Portal™, patent-pending innovations which establish a LiveRoof green roof as a unified, naturally functioning ecosystem. The Soil Elevator, a removable insert, lines the inside of modules so soil can be filled above the top. When the modules are installed side-by-side, and the Soil Elevators are removed, an uninterrupted layer of soil and vegetative surface then extends across the entire rooftop. The Moisture Portal™ is an opening on the sides of the modules and establishes soil-to-soil contact between them. Plant roots are free to grow in a natural way from one module to the next. This ecological integration between and above LiveRoof modules maximizes the cohesiveness of the soil and plant roots to optimize plant health, long-term green roof sustainability, and green roof benefits.
