New Orleans was catastrophically affected by what Raymond B. Seed called "the worst engineering disaster in the world since [[Chernobyl disaster|Chernobyl]]", when [[2005 levee failures in Greater New Orleans|the federal levee system failed]] during [[Hurricane Katrina]] on August 29, 2005.<ref name="Baker">[http://www.americanheritage.com/articles/magazine/ah/2006/2/2006_2_23.shtml Kevin Baker] {{webarchive |url=https://web.archive.org/web/20091005062625/http://www.americanheritage.com/articles/magazine/ah/2006/2/2006_2_23.shtml |date=October 5, 2009 }} "The Future of New Orleans", ''American Heritage'', April/May 2006.</ref> By the time the hurricane approached the city on August 29, 2005, most residents had evacuated. As the hurricane passed through the [[Gulf Coast of the United States|Gulf Coast region]] that day, the city's [[Flood Control Act of 1965|federal flood protection]] system failed, resulting in the worst [[civil engineering]] disaster in American history at the time.<ref>{{cite news |first=Bob |last=Marshall |url=http://www.nola.com/news/t-p/frontpage/index.ssf?/base/news-4/1133336859287360.xml |title=17th Street Canal levee was doomed |work=The Times-Picayune |date=November 30, 2005 |access-date=March 12, 2006 |url-status=dead |archive-url=https://web.archive.org/web/20060907073947/http://www.nola.com/news/t-p/frontpage/index.ssf?%2Fbase%2Fnews-4%2F1133336859287360.xml |archive-date=September 7, 2006}}</ref> Floodwalls and [[levee]]s constructed by the [[United States Army Corps of Engineers]] failed below design specifications and 80% of the city flooded.

====Hurricane Rita====

The city was declared off-limits to residents while efforts to clean up after [[Hurricane Katrina]] began. The approach of [[Hurricane Rita]] in September 2005 caused repopulation efforts to be postponed,<ref>{{cite news |url=http://www.cnn.com/2005/US/09/15/katrina.impact/index.html |title=Mayor: Parts of New Orleans to reopen |date=September 15, 2005 |publisher=CNN |access-date=May 2, 2006 |archive-date=June 18, 2006 |archive-url=https://web.archive.org/web/20060618093145/http://www.cnn.com/2005/US/09/15/katrina.impact/index.html |url-status=live }}</ref> and the [[Lower Ninth Ward]] was reflooded by Rita's storm surge.<ref name="184_Katrina1"/>

Because of the scale of damage, many people resettled permanently outside the area. Federal, state, and local efforts supported recovery and rebuilding in severely damaged neighborhoods. The U.S. Census Bureau in July 2006 estimated the population to be 223,000; a subsequent study estimated that 32,000 additional residents had moved to the city as of March 2007, bringing the estimated population to 255,000, approximately 56% of the pre-Katrina population level. Another estimate, based on utility usage from July 2007, estimated the population to be approximately 274,000 or 60% of the pre-Katrina population. These estimates are somewhat smaller to a third estimate, based on mail delivery records, from the Greater New Orleans Community Data Center in June 2007, which indicated that the city had regained approximately two-thirds of its pre-Katrina population.<ref>[http://www.nola.com/news/t-p/frontpage/index.ssf?/base/news-8/1186642536113410.xml&coll=1 "N.O. head count gains steam"] {{webarchive |url=https://web.archive.org/web/20090701223143/http://www.nola.com/news/t-p/frontpage/index.ssf?%2Fbase%2Fnews-8%2F1186642536113410.xml&coll=1 |date=July 1, 2009 }}, ''The Times-Picayune'', August 9, 2007.
