The Iowa Events Center consists of the existing Community Choice Credit Union Convention Center, the existing Polk County Convention Complex, the new Hy-Vee Hall, and the new Wells Fargo Arena. The new buildings were designed by Populous (formerly HOK Sport Venue Event), who were also the architects of the renovated Principal Park in Des Moines, the United Center in Chicago, and many other arenas and stadiums in the United States. The project cost $217 million, making this the largest public project in Iowa history. Funding for the project came from Polk County and its cities, private donations, and the Vision Iowa Fund that Gov. Tom Vilsack signed into law in 2000. Gambling profits from the Prairie Meadows casino in nearby Altoona are expected to pay off the debt.
