The University of Wisconsin Great Lakes WATER Institute (GLWI) building is situated on MilwaukeeÃ¢â‚¬â„¢s inner harbor. Surrounded by paved roadways and cement docks and walkways, the building itself supports 86,700 ft2 of horizontal asphalt and pea gravel rooftop.
In 2003, a 7,600 ft2 first-floor section of the GLWI roof was converted to a vegetated Ã¢â‚¬ËœgreenÃ¢â‚¬â„¢ roof in order to demonstrate an innovative and cost-effective stormwater Best Management Practice (BMP) for the Milwaukee metro area and University of Wisconsin System. The installation and maintenance of the GLWI green roof offers a working model of an aesthetically-impressive stormwater mitigation strategy that is especially suited to dense urban development. In collaboration with the Milwaukee Metropolitan Sewerage District through their Stormwater BMP Partnership Program, funding has been secured to make this pilot GLWI green roof a reality.
