Reconstruction of New Orleans Reconstruction of New Orleans The reconstruction of New Orleans refers to the rebuilding process endured by the city of New Orleans after Hurricane Katrina destroyed much of the city in August 2005. The storm caused levees to fail, releasing tens of billions of gallons of water. The levee failure contributed to extensive flooding in 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. Wind
Hurricane preparedness for New Orleans from the Mississippi River. In 1947, the Fort Lauderdale hurricane struck the New Orleans area. There was moderate wind damage. Flood prevention was largely successful in Orleans Parish, but there was severe flooding in the new East Jefferson suburbs near the Lake. Hurricane Flossy in 1956 resulted in flooding in parts of Eastern New Orleans. Hurricane Betsy in 1965 alerted a new generation to the threat posed by major hurricanes. As radar showed the storm heading for the city, a mandatory evacuation of Eastern New Orleans was declared. The Mississippi River-Gulf Outlet Canal channeled storm surge into the metro area.
