Can someone please help me and list the main cause New Orleans was destroyed.
However, the city-proper flooded because the US Army Corps of Engineers built poorly-designed flood-walls along drainage canals connected to Lake Pontchartrain. The walls failed at the height of the storm surge, with water levels almost 13 feet above sea level. That is what caused the horrific scenes you saw on TV, with people trapped on their roofs, etc.
In February of 2008, a federal judge agreed the city flooded due to negligence by the federal government (the US Army Corps of Engineers is a federal agency). However, he also ruled the federal government has immunity from liability for negligence.
The levee failures prompted investigations of their design and construction which belongs solely to the US Army Corps of Engineers as mandated in the Flood Control Act of 1965. There was also an investigation of the responses from federal, state and local governments, resulting in the resignation of Federal Emergency Management Agency director Michael D. Brown. Conversely, the National Hurricane Center and National Weather Service were widely commended for accurate forecasts and abundant lead time.[6] Three years later, thousands of displaced residents in Mississippi and Louisiana were still living in trailers.
As the eye of Hurricane Katrina swept to the northeast, it subjected the city to hurricane conditions for hours. Although power failures prevented accurate measurement of wind speeds in New Orleans, there were a few measurements of hurricane-force winds. From this the NHC concluded that it is likely that much of the city experienced sustained winds of Category 1 or Category 2 strength.
Katrina_s storm surge led to 53 levee breaches in the federally built levee system protecting metro New Orleans. Failures occurred in New Orleans and surrounding communities, especially St. Bernard Parish. The Mississippi River Gulf Outlet (MR-GO) breached its levees in approximately 20 places, flooding much of east New Orleans, most of Saint Bernard Parish and the East Bank of Plaquemines Parish. The major levee breaches in the city included breaches at the 17th Street Canal levee, the London Avenue Canal, and the wide, navigable Industrial Canal, which left approximately 80% of the city flooded.[39]
Most of the major roads traveling into and out of the city were damaged. The only routes out of the city were the westbound Crescent City Connection and the Huey P. Long Bridge, as large portions of the I-10 Twin Span Bridge traveling eastbound towards Slidell, Louisiana had collapsed. Both the Lake Pontchartrain Causeway and the Crescent City Connection only carried emergency traffic.[40]
On August 29, at 7:40 a.m. CDT, it was reported that most of the windows on the north side of the Hyatt Regency New Orleans had been blown out, and many other high rise buildings had extensive window damage.[41] The Hyatt was the most severely damaged hotel in the city, with beds reported to be flying out of the windows. Insulation tubes were exposed as the hotel_s glass exterior was completely sheared off.
The Superdome, which was sheltering many people who had not evacuated, sustained significant damage. Two sections of the Superdome_s roof were compromised and the dome_s waterproof membrane had essentially been peeled off. Louis Armstrong New Orleans International Airport was closed before the storm but did not flood. On August 30, it was reopened to humanitarian and rescue operations. Limited commercial passenger service resumed at the airport on September 13 and regular carrier operations resumed in early October.[43]
Levee breaches in New Orleans also caused widespread loss of life, with over 700 bodies recovered in New Orleans by October 23, 2005.[44] Some survivors and evacuees reported seei
that would be the main reason i_d have thought...the reason behind everything else happening would have been because of the destruction caused from the hurricane katrina...
