A MODEL OF MUNICIPAL LEADERSHIP FROM URBAN HEAT ISLAND REDUCTION TO STORMWATER MANAGER AND BIODIVERSITY BOOSTER, THIS PROJECT SHOWS HOW VISION AND SEEING THE BIGGER PICTURE CAN CREATE A MORE SUSTAINABLE CITY t is not often that a roof serves butterflies and basketball players, but the new roof at the Target Center in Minneapolis does both. That is because the Target Center’s new green roof not only provides shelter to the National Basketball Association’s Minnesota Timberwolves and their fans, but it also features vegetation (including Lupines) designed to attract the endangered Karner Blue Butterfly. But attracting butterflies was not the main reason the City of Minneapolis went with a green roof when it replaced the existing EDPM roof on the sports arena. The City was experiencing a problem with combined sewer overflow problems, and every drop of water that fell on the old roof flowed to the sidewalk, into the sewer system and then into the Mississippi River. The City projects that the green roof will manage one million gallons of stormwater each year, saving USD $1.2 to $1.8 million annually Besides noting the difficulties of designing such a large-scale retrofit project, the judges applauded the City for its courage to tackle such a complex project on a highly public, intensively utilized place. “It was a big gamble for a City Council showing superior leadership,” they said, but one that has paid off in many tangible and intangible ways and ultimately, served to create a more sustainable Minneapolis.
