Levee breaches in the federally built Hurricane Protection System and the resulting flooding that occurred on August 29, 2005 in the New Orleans vicinity. On Monday, August 29, 2005, there were over 50 failures of the levees and flood walls protecting New Orleans, Louisiana, and its suburbs following passage of Hurricane Katrina.
This story—50 years in the making—is heart-wrenching. Millions of dollars were squandered in building a levee system with respect to these outfall canals which was known to be inadequate by the corps's own calculations. [49] Duval's decision left the New Orleans Sewerage & Water Board and Orleans Levee District as defendants in the lawsuit ...
The Southeast Louisiana Flood Protection Authority (SLFPA) was established by Louisiana state law Revised Statute §38:330.1 in September 2006. Its operation began in January 2007. The Authority consists of two regional levee boards which oversee flood protection in the Greater New Orleans area on the east and west banks of the Mississippi ...
The levee failure contributed to extensive flooding in the New Orleans area and surrounding parishes. About 80% of all structures in Orleans Parish sustained water damage. Over 204,000 homes were damaged or destroyed, and more than 800,000 citizens displaced—the greatest displacement in the United States since the Dust Bowl of the 1930s. [1]
The breach at the 17th Street Canal Levee, a levee-floodwall combination, was found to be about 300 feet (100 m) long. The Corps began operating on an initial hypothesis that the force of the water overtopped the floodwall and scoured the structure from behind and then moved the levee wall horizontally about 20 feet (6.1 m).
The levee system has been massively overhauled ... Louisiana’s 17 oil refineries account for nearly one-fifth of the U.S. refining capacity and its two liquefied natural gas export terminals ...
The U.S. levee system is a massive — and, often, not fully understood — piece of infrastructure. What was considered adequate protection when levees were originally built can't withstand wet ...
The Sewerage & Water Board had the responsibility of draining the city along with constructing a modern sewage and tap water system for the city, which, at the time, still relied heavily on cisterns and outhouses. (A different entity, the Orleans Levee Board, was in charge of supervision of the city's levee and floodwall system.)
