The city of New Orleans has filed a $77 billion damage claim against the Army Corps of Engineers. The Corps was responsible for the levees that failed after Hurricane Katrina swept through -- leading to flooding that caused most of the damage in the city.
The city's claim came through the Federal Tort Act.
The Corps has six months to accept, settle or reject claims. After that, claimants can sue the federal government.
FEMA has provided $6.3 billion in recovery funds, $13.2 billion in flood insurance claims. (CNN)
