Hurricane Katrina: Effects & Future Prevention
On August 29, 2005, Hurricane Katrina wreaked havoc on the gulf coast of the United States, east of New Orleans, with the storm's eye passing within 10 to 15 miles of the city. The effect on New Orleans, along with most of the coastal areas, were devastating.

In the aftermath of the storm, about 80% of the city, much of which is below sea level, was flooded. Damages are estimated to exceed $200 billion, making Katrina one of the most economically costly hurricanes to ever strike the United States. Reacting to the widespread destruction, the 109th Congress enacted two supplementary appropriation bills totaling $62.3 billion for emergency response and recovery needs. Frighteningly, the death toll has been estimated to be more than 1,200. In addition, tens of thousands of citizens were forced to evacuate to other parts of the Nation.

Besides taking its toll on the human, social, and psychological fabric of the city, the storm had a notable effect on the city's economy, its labor market and dynamics, and its individual businesses. credit


At President Bush's request, Congress has provided a total of $16.7 billion in Federal funds under the U.S. Department of Housing and Urban Development's Community Development Block Grants program to help rebuild damaged housing and other infrastructure. This unprecedented program represents the largest single housing recovery program in U.S. history.

The U.S. Army Corps of Engineers repaired and restored 220 miles of floodwalls and levees since September 2005. With a few exceptions, the New Orleans hurricane protection system is in equal or better condition than it was when Katrina hit. Levees and flood walls have been armored to protect against erosion from possible overtopping in several areas, and pumping stations are being storm proofed. Floodgates have been added at the outfall canals to protect against storm surge and a tree cutting program on existing levees for protection is ongoing.credit
