Minneapolis Expected to Approve $5.3 M Green Roof for Target Center
The City Council of Minneapolis is expected to approve a $5.3 million green roof for the Target Center. The project is the city’s most expensive project since it bought the arena, Star Tribune reports.
Consultants were initially concerned that a heavier green roof would overload the arena and advised against it. But after recalculation, they adjusted for a lower snow-load factor and looked into roofs that use shallower and lighter rooting layers for planting.
The roof is expected to feature a growing zone that is 2.75 inches thick for much of the 115,000-square-foot main roof, and 3.5 inches in a 32-foot-wide edge where there is more structural support.
