On the evening of April 13, 2006, a confirmed EF2 tornado struck Iowa City, causing severe property damage and displacing many from their homes, including many University of Iowa students. It was the first tornado ever recorded to hit the city directly. No serious injuries were reported in the Iowa City area. A popular Dairy Queen, which had been in business for 54 years, was a victim of the storm (but it reopened in late September), along with two large car dealerships, and several other businesses along Riverside Drive and Iowa Highway 1. The 134-year-old Saint Patrick's Catholic Church was heavily damaged only minutes after Holy Thursday Mass, with most of its roof destroyed. The building was ruled a total loss and has since been demolished. The downtown business district as well as the eastern residential area and several parks suffered scattered damage of varying degrees. Additionally, several houses in the sorority row area were destroyed. The Alpha Chi Omega house was nearly destroyed, though no one was injured and the building was later razed. Cleanup efforts were under way almost immediately as local law enforcement, volunteer workers from all over the state, and Iowa City residents and college students worked together to restore the city. The total cost of damage was estimated at around $12 million.
