And certainly a football field does not make a good convention center addition, says Heywood Sanders. Indianapolis, Atlanta, and St. Louis are the cities trying to use football fields as convention center space, and none has worked well. “The flat floor space is about 150,000 to 180,000 square feet. That’s not very much space,” he says. A company displaying tractors or construction equipment, for example, does not want to be surrounded by a bunch of empty seats.
The stadium touted by the Chargers would be several blocks away from the convention center; thus, it would have two strikes against it immediately.
A football stadium will work for some conventions: “Social, religious, and fraternal groups like to have an open arena for large assemblies — say, 10,000 or 15,000 Baptists. But they do not necessarily constitute the most desirable convention business,” says Sanders. That is to say, they may not utilize the “ahem” amenities.
