Hurricane Katrina was the largest and most costly disaster in American history. More than 1,400 Louisiana residents lost their lives. Katrina produced the first mandatory evacuation in New Orleans history, and the largest displacement of people in U.S. history; 1.3 million. More than 200,000 New Orleanians remain displaced. While federal and state governments continue to respond to this disaster, this book has identified significant control weaknesses, specifically in the Federal Emergency Management Agency (FEMA), Individuals and Households Program (IHP), and in the Department of Homeland Security (DHS)'s purchase card program which has resulted in significant fraud, waste, and abuse. These lessons are particularly important because funding that is lost to fraud, waste, and abuse reduces the amount of money that could be delivered to victims in need. This book looks at the many challenges facing New Orleans in the aftermath of Hurricane Katrina, including the rebuilding efforts, insurance losses, re-establishing the health care system and hospitals within the system, and the federal government's liability depending on the theory of the levee failures in New Orleans. The authors summarise the impact of the hurricane, report on the status of recovery efforts, explore the reasons why the recovery has proceeded as it has, and suggest issues that Congress might wish to consider in order to better plan for future disasters and to improve the capability of all levels of government to respond effectively.
