Governor Kathleen Babineaux Blanco's New Orleans Hurricane Relief Foundation was created on August 30, 2005.  Local governments across the . sent aid in the form of ambulances, search teams and disaster supplies. Shelters to house those displaced were established as far away as Utah . The Arkansas Department of Parks and Tourism contacted travelers having reservations at state parks to see if the travelers would voluntarily give up their reservations to persons fleeing Katrina, primarily in the southern part of the state where refugees had already taken shelter (at Lake Chicot State Park , just across the Louisiana state line, a 26-member family from New Orleans, including a grandmother on oxygen, occupied seven of the park's cabins). In any event, refugees at state parks would not be evicted for prior reservations, and those with reservations but no room would either get space at another state park or a gift certificate.
The hurricane protection failures in New Orleans prompted a lawsuit against the US Army Corps of Engineers (USACE), the designers and builders of the levee system as mandated by the Flood Control Act of 1965. Responsibility for the failures and flooding was laid squarely on the Army Corps in January 2008, but the federal agency could not be held financially liable due to sovereign immunity in the Flood Control Act of 1928. There was also an investigation of the responses from federal, state and local governments, resulting in the resignation of Federal Emergency Management Agency (FEMA) director Michael D. Brown, and of New Orleans Police Department (NOPD) Superintendent Eddie Compass.
