Past hurricanes and Katrina preparation

Hurricane Katrina was the third time the dome had been used as a public shelter. It was previously used in 1998 during Hurricane Georges and again in 2004 during Hurricane Ivan, on both occasions for less than two days at most. Even though the dome never lost power, air conditioning or running water during any of those storms, Superdome manager Doug Thornton recommended after Hurricane Georges for the dome to not be used as a shelter for anybody but special-needs evacuees. In addition, a Bleacher Report article quotes Thornton saying "We're not a hospital. We're not a hotel. We can't house people for five or six days."

Despite these previous periods of emergency use, as Katrina approached the city, officials had not stockpiled enough generator fuel, food, and other supplies to handle the needs of the thousands of people seeking safety there. According to an article in Time, "Over the years city officials have stressed that they didn't want to make it too comfortable at the Superdome since it was always safer to leave the city altogether. It's not a hotel," said the emergency preparedness director for St. Tammany Parish to the Times-Picayune in 1999."

The Superdome was built to withstand most natural catastrophes. The roof was estimated to be able to withstand winds with speeds of up to 200 mph (320 km/h) and flood waters were not expected to reach the second level 35 feet (11 m) from the ground. However, when looking into the origins of the claims about 200 mph (320 km/h) wind security in the Superdome, CNN reported that no engineering study had ever been completed on the amount of wind the structure could withstand. The building's engineering study was underway as Hurricane Katrina approached and was put on hold. It was used as an emergency shelter although it was neither designed nor tested for the task. It was already known that the generators would not provide lights or air conditioning for the whole dome if the power failed, and also pumps providing water to second-level restrooms wouldn't function.
