On August 31, 2005, in the wake of Hurricane Katrina, the Harris County Department of Homeland Security and Emergency Management and the State of Louisiana came to an agreement to allow at least 25,000 evacuees from New Orleans, especially those that were sheltered in the Louisiana Superdome, to move to the Astrodome until they could return home.
The evacuation began on September 1, 2005.
All scheduled events for the final four months of 2005 at the Astrodome were cancelled.
Overflow refugees were held in the surrounding Reliant Park complex.
There was a full field hospital inside the Reliant Arena, which cared for the entire Katrina evacuee community.

The entire Reliant Park complex was scheduled to be emptied of hurricane evacuees by September 17, 2005.
Originally, the Astrodome was planned to be used to house evacuees until December.
However, the surrounding parking lots were needed for the first Houston Texans home game.
Arrangements were made to help Katrina evacuees find apartments both in Houston and elsewhere in the United States.
By September 16, 2005, the last of the hurricane evacuees living in the Astrodome had been moved out either to the neighboring Reliant Arena or to permanent housing north of Houston.
As of September 20, 2005, the remaining Katrina evacuees were relocated to Arkansas due to Hurricane Rita.
