Supervalu to build convention center

EDEN PRAIRIE, Minn. Supervalu has announced plans to build its own convention centre in Eden Prairie, Minn. The approximately 4,600-square-foot building will be added to the retailer's headquarters and will include a green roof and rainwater gardens to curb storm water run-off.

"We really want this conference center to be able to bring all these people to what we consider our home in Eden Prairie," said Neil Libson, director of office facilities.
