The flooding destroyed most of New Orleans's transportation and communication facilities, leaving tens of thousands of people who did not evacuate the city prior to landfall with little access to food, shelter, and other basic necessities. The disaster in New Orleans prompted a massive national and international response effort, including federal, local, and private rescue operations to evacuate those displaced from the city in the following weeks. After the storm, multiple investigations concluded that the U.S. Army Corps of Engineers, which had designed and built the region's levees decades earlier, was responsible for the failure of the flood-control systems. However, federal courts later ruled that the Corps could not be held financially liable due to sovereign immunity in the

Katrina was the earliest 11th named storm on record, before being surpassed by Tropical Storm Kyle on August 14, 2020. The destruction and loss of life caused by the storm prompted the name Katrina to be retired by the World Meteorological Organization in April 2006. On January 4, 2023, the National Hurricane Center (NHC) updated the Katrina fatality data based on a report by Rappaport (2014) which reduced the number from an estimated 1,833 to 1,392. The same NHC report also revised the total damage estimate keeping Hurricane Katrina as the costliest storm ever––$190 billion according to NOAA's National Centers for Environmental Information.

The United States Coast Guard began pre-positioning resources in a ring around the expected impact zone and activated more than 400 reservists. On August 27, it moved its personnel out of the New Orleans region prior to the mandatory evacuation.

(R-IN) inquired as to why Bush's declaration of state of emergency of August 27 had not included the coastal parishes of Orleans, Jefferson, and Plaquemines. The declaration actually did not include any of Louisiana's coastal parishes, whereas the coastal counties were included in the declarations for Mississippi and Alabama. Brown testified that this was because Louisiana Governor Blanco had not included those parishes in her initial request for aid, a decision that he found "shocking". After the hearing, Blanco released a copy of her letter, which showed she had requested assistance for "all the southeastern parishes including the City of New Orleans" as well specifically naming 14 parishes, including Jefferson, Orleans, St. Bernard, and Plaquemines. Voluntary and mandatory evacuations were issued for large areas of southeast Louisiana as well as coastal Mississippi and Alabama. About 1.2 million residents of the Gulf Coast were covered under a voluntary or mandatory evacuation order.

(NHC) realized that Katrina had yet to make the turn toward the Florida Panhandle and ended up revising the predicted track of the storm from the panhandle to the Mississippi coast. The National Weather Service's New Orleans/Baton Rouge office issued a vividly worded bulletin on August 28 predicting that the area would be "uninhabitable for weeks" after "devastating damage" caused by Katrina, which at that time rivaled the intensity of Hurricane Camille. During video conferences involving the president later that day and on August 29, NHC director Max Mayfield expressed concern that Katrina might push its storm surge over the city's levees and flood walls. In one conference, he stated, "I do not think anyone can tell you with confidence right now whether the levees will be topped or not, but that's obviously a very, very great concern."

On August 28, Alabama Governor Bob Riley declared a state of emergency for the approaching Hurricane Katrina. On the same day, he requested President Bush to declare "expedited major disaster declaration" for six counties of South Alabama, which was quickly approved. Three hundred fifty national guardsmen were called on duty by August 30. The state of Mississippi activated its National Guard on August 26 in preparation for the storm's landfall. Additionally, the state government activated its Emergency Operations Center the next day, and local governments began issuing evacuation orders. By 6:00 p.m. CDT on August 28, 11 counties and cities issued evacuation orders, a number which increased to 41 counties and 61 cities by the following morning. Moreover, 57 emergency shelters were established on coastal communities, with 31 additional shelters available to open if needed.

Louisiana

In Louisiana, the state's hurricane evacuation plan calls for local governments in areas along and near the coast to evacuate in three phases, starting with the immediate coast 50 hours before the start of tropical-storm-force winds. Persons in areas designated Phase II begin evacuating 40 hours before the onset of tropical storm winds and those in Phase III areas (including New Orleans) evacuate 30 hours before the start of such winds. Many private caregiving facilities that relied on bus companies and ambulance services for evacuation were unable to evacuate their charges because they waited too long. Louisiana's Emergency Operations Plan Supplement 1C (Part II, Section II, Paragraph D) calls for use of school and other public buses in evacuations. Although buses that later flooded were available to transport those dependent upon public transportation, not enough bus drivers were available to drive them as Governor Blanco did not sign an emergency waiver to allow any licensed driver to transport evacuees on school buses. By August 26, many of the computer models had shifted the potential path of Katrina westward from the Florida Panhandle, putting the city of New Orleans directly in the center of their track probabilities; the chances of a direct hit were forecast at 17%, with strike probability rising to 29% by August 28. This scenario was considered a potential catastrophe because some parts of New Orleans and the metro area are below sea level. Since the storm surge produced by the hurricane's right-front quadrant (containing the strongest winds) was forecast to be , while the levees offered protection to , emergency management officials in New Orleans feared that the storm surge could go over the tops of levees protecting the city, causing major flooding. At a news conference at 10 a.m. EDT on August 28, shortly after Katrina was upgraded to a Category 5 storm, New Orleans mayor Ray Nagin ordered the first-ever mandatory evacuation of the city, calling Katrina "a storm that most of us have long feared". The city government also established several "refuges of last resort" for citizens who could not leave the city, including the massive Louisiana Superdome, which sheltered approximately 26,000 people and provided them with food and water for several days as the storm came ashore. Some estimates claimed that 80% of the 1.3 million residents of the greater New Orleans metropolitan area evacuated, leaving behind substantially fewer people than remained in the city during the Hurricane Ivan evacuation.

). However, in February 2021, a severe winter storm struck the United States, causing a major power failure in Houston, which caused at least $195 billion (2021 USD) in damage in Texas. It surpassed both Katrina and Harvey to become the single-costliest natural disaster recorded in the United States. The death toll from Katrina is uncertain, with reports differing by hundreds. According to the National Hurricane Center, 1,836 fatalities can be attributed to the storm: 1 in Kentucky, 2 each in Alabama, Georgia, and Ohio, 14 in Florida, 238 in Mississippi, and 1,577 in Louisiana. However, 135 people remain categorized as missing in Louisiana, and many of the deaths are indirect, but it is almost impossible to determine the exact cause of some of the fatalities. A 2008 report by the Disaster Medicine and Public Health Preparedness journal indicates that 966 deaths can be directly attributed to the storm in Louisiana, including out of state evacuees, and another 20 indirectly (such as firearm-related deaths and gas poisoning). Due to uncertain causes of death with 454 evacuees, an upper-bound of 1,440 is noted in the paper. A follow-up study by the Louisiana Department of Health & Hospitals determined that the storm was directly responsible for 1,170 fatalities in Louisiana.

New Orleans

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; based on this information, the NHC concluded that much of the city likely experienced sustained winds of Category 1 or 2 hurricane strength. Katrina's storm surge caused 53 levee breaches in the federally built levee system protecting metro New Orleans and the failure of the 40 Arpent Canal levee.

Mississippi

The Gulf coast of Mississippi suffered extremely severe damage from the impact of Hurricane Katrina on August 29, leaving 238 people dead, 67 missing, and billions of dollars in damage: bridges, barges, boats, piers, houses, and cars were washed inland. Katrina traveled up the entire state; as a result, all 82 counties in Mississippi were declared disaster areas for federal assistance, 47 for full assistance. After making a brief initial landfall in Louisiana, Katrina had made its final landfall near the state line, and the eyewall passed over the cities of Bay St. Louis and Waveland as a Category 3 hurricane with sustained winds of . Katrina's powerful right-front quadrant passed over the west and central Mississippi coast, causing a powerful storm surge, which penetrated inland in many areas and up to inland along bays and rivers; in some areas, the surge crossed

All three coastal counties of the state were severely affected by the storm. Katrina's surge was the most extensive, as well as the highest, in the documented history of the United States; large portions of Hancock, Harrison, and Jackson counties were inundated by the storm surge, in all three cases affecting most of the populated areas. Surge covered almost the entire lower half of Hancock County, destroying the coastal communities of Clermont Harbor and Waveland, much of Bay St. Louis, and flowed up the Jourdan River, flooding Diamondhead and Kiln. In Harrison County, Pass Christian was completely inundated, along with a narrow strip of land to the east along the coast, which includes the cities of Long Beach and Gulfport; the flooding was more extensive in communities such as D'Iberville, which borders Back Bay. Biloxi, on a peninsula between the Back Bay and the coast, was particularly hard hit, especially the low-lying Point Cadet area. In Jackson County, storm surge flowed up the wide river estuary, with the combined surge and freshwater flooding cutting the county in half.

Aftermath


Economic effects

The economic effects of the storm reached high levels.

The forestry industry in Mississippi was also affected, as of forest lands were destroyed. The total loss to the forestry industry from Katrina is calculated to rise to about $5 billion. Furthermore, hundreds of thousands of local residents were left unemployed. Before the hurricane, the region supported approximately one million non-farm jobs, with 600,000 of them in New Orleans. It is estimated that the total economic impact in Louisiana and Mississippi may eventually exceed $150 billion. Forensic accountants were involved in the assessment of economic damages resulting from this catastrophe.

told ABC News: "There was shooting going on. There was sniping going on. Over the first week of September, law and order were gradually restored to the city." Several shootings occurred between police and New Orleans residents, some involving police misconduct; including an incident where police officers killed two unarmed civilians and seriously injured four others at Danziger Bridge. Five former police officers pleaded guilty to charges connected to the Danziger Bridge shootings in the aftermath of the hurricane. Six other former or existing officers appeared in court in June 2011. Overall, a number of arrests were made throughout the affected area, including some near the New Orleans Convention Center. A temporary jail was constructed of chain link cages in the New Orleans Union Passenger Terminal, the city's main train station. On September 30, the New Orleans Police Department confirmed that 12 police officers were participating in looting and property theft. In West Virginia, where roughly 350 refugees were located, local officials took fingerprints to run criminal background checks on the refugees. The background checks found that 45% of the refugees had a criminal record of some nature, and that 22% had a violent criminal record. Media speculation fueled a popular perception that the displaced New Orleans residents brought a wave of crime into the communities where they relocated, however, detailed studies of crime statistics in these communities did not reveal a significant increase in violent crime.


Government response

Within the United States and as delineated in the National Response Plan, disaster response and planning is first and foremost a local government responsibility. When local government exhausts its resources, it then requests specific additional resources from the county level. The request process proceeds similarly from the county to the state to the federal government as additional resource needs are identified. Many of the problems that arose developed from inadequate planning and back-up communication systems at various levels. Some

, etc.) to more than 700,000 applicants—families and individuals. However, only one-fifth of the trailers requested in Orleans Parish were supplied, resulting in an enormous housing shortage in the city of New Orleans. Many local areas voted to not allow the trailers, and many areas had no utilities, a requirement prior to placing the trailers. To provide for additional housing, FEMA has also paid for the hotel costs of 12,000 individuals and families displaced by Katrina through February 7, 2006, when a final deadline was set for the end of hotel cost coverage. After this deadline, evacuees were still eligible to receive federal assistance, which could be used towards either apartment rent, additional hotel stays, or fixing their ruined homes, although FEMA no longer paid for hotels directly. As of March 30, 2010, there were still 260 families living in FEMA-provided trailers in Louisiana and Mississippi. Law enforcement and public safety agencies, from across the United States, provided a " mutual aid" response to Louisiana and New Orleans in the weeks following the disaster. Many agencies responded with manpower and equipment from as far away as California, Michigan, Nevada, New York, and Texas. This response was welcomed by local Louisiana authorities as their staff were either becoming fatigued, stretched too thin, or even quitting from the job. Two weeks after the storm, more than half of the states were involved in providing shelter for evacuees. By four weeks after the storm, evacuees had been registered in all 50 states and in 18,700 zip codes—half of the nation's residential postal zones. Most evacuees had stayed within , but 240,000 households went to Houston and other cities over away and another 60,000 households went over away.


Criticism of government response

The criticisms of the government's response to Hurricane Katrina primarily consisted of criticism of mismanagement and lack of leadership in the relief efforts in response to the storm and its aftermath. More specifically, the criticism focused on the delayed response to the flooding of New Orleans, and the subsequent state of chaos in the city. The neologism ''Katrina

Nagin and Blanco were criticized for failing to implement New Orleans's evacuation plan and for ordering residents to a shelter of last resort without any provisions for food, water, security, or sanitary conditions. Perhaps the most important criticism of Nagin was that he delayed his emergency evacuation order until 19 hours before landfall, which led to hundreds of deaths of people who could not find any way out of the city.

Additionally, it placed responsibility for the disaster on all three levels of government.

International response

Over seventy countries pledged monetary donations or other assistance. Cuba and Venezuela (both considered as hostile to US government interest) were the first countries to offer assistance, pledging over $1 million, several mobile hospitals, water treatment plants, canned food, bottled water, heating oil, 1,100 doctors and 26.4 metric tons of medicine, though this aid was rejected by the U.S. government. Kuwait made the largest single pledge, $500 million; other large donations were made by Qatar and the United Arab Emirates (each $100 million), South Korea ($30 million), Australia ($10 million), India, China (both $5 million), New Zealand ($2 million), Pakistan ($1.5 million), Norway ($1.8 million), and Bangladesh ($1 million).

, Service International, "A River of Hope", The Church of Jesus Christ of Latter-day Saints, and many other charitable organizations provided aid to victims in the aftermath of the storm. They were not allowed into New Orleans proper by the National Guard for several days after the storm because of safety concerns. These organizations raised US$4.25 billion in donations from the public, with the Red Cross receiving over half of these donations. Some smaller organizations and individuals ignored the access restrictions and provided early relief. For example, two privately chartered planes from FasterCures evacuated 200 patients from Charity Hospital in New Orleans. Volunteers from the Amateur Radio Emergency Service provided communications in areas where the communications infrastructure had been damaged or totally destroyed, relaying everything from 911 traffic to messages home. In Hancock County, Mississippi, ham radio operators provided the only communications into or out of the area and even served as 911 dispatchers. Many private corporations also contributed to relief efforts. On September 13, 2005, it was reported that corporate donations amounted to $409 million, and were expected to exceed $1 billion. During and after the Hurricanes Katrina, Wilma and Rita, the American Red Cross had opened 1,470 shelters and registered 3.8 million overnight stays. None were allowed in New Orleans, however. A total of 244,000 Red Cross workers (95% of which were non-paid volunteers) were utilized throughout these three hurricanes. In addition, 346,980 comfort kits (including such basic necessities as toothpaste, soap, washcloths, and toys for children) and 205,360 cleanup kits (containing brooms, mops, and bleach) were distributed. For mass care, the organization served 68 million snacks and meals to victims of the disasters and to rescue workers. The Red Cross also had its Disaster Health services meet 596,810 contacts, and Disaster Mental Health services met 826,590 contacts. Red Cross emergency financial assistance was provided to 1.4 million families. Hurricane Katrina was the first natural disaster in the United States in which the American Red Cross utilized its "Safe and Well" family location website. Direct Relief provided a major response in the Gulf states so health providers could treat the local patients and evacuees. Direct Relief furnished $10 million in medical material aid and cash grants to support clinics and health centers in the area. In the year following Katrina's strike on the Gulf Coast, The Salvation Army allocated donations of more than $365 million to serve more than 1.7 million people in nearly every state. The organization's immediate response to Hurricane Katrina included more than 5.7 million hot meals and about 8.3 million sandwiches, snacks, and drinks served in and around New Orleans. Its SATERN network of amateur radio operators picked up where modern communications left off to help locate more than 25,000 survivors. Salvation Army pastoral care counselors were on hand to comfort the emotional and spiritual needs of 277,000 individuals. As part of the overall effort, Salvation Army officers, employees, and volunteers contributed more than 900,000 hours of service.


Analysis of New Orleans levee failures

According to a modeling exercise conducted by the U.S. Army Corps of Engineers (USACE), two-thirds of the deaths in Greater New Orleans were due to levee and flood wall failure. On April 5, 2006, months after independent investigators had demonstrated that levee failures were not caused by natural forces beyond intended design strength, Lieutenant General Carl Strock, chief of engineers and commander of the Corps of Engineers, testified before the United States Senate Subcommittee on Energy and Water that "We have now concluded we had problems with the design of the structure." A June 2007 report released by the American Society of Civil Engineers determined that the failures of the levees and flood walls in New Orleans were found to be primarily the result of system design and construction flaws. The U.S. Army Corps of Engineers had been federally mandated in the Flood Control Act of 1965 with responsibility for the conception, design, and construction of the region's flood-control system. All of the major studies in the aftermath of Katrina concluded that the USACE was responsible for the failure of the levees. This was primarily attributed to a decision to use shorter steel sheet pilings during construction in an effort to save money. According to a report published in August 2015 in the official journal of the World Water Council, the Corps misinterpreted the results of a 1985 study and wrongly concluded that sheet piles in the flood walls needed to be driven to depths of only instead of between . That decision saved approximately US$100 million, but significantly reduced overall engineering reliability. In January 2008, Judge

. Exactly ten years after Katrina, J. David Rogers, lead author of a new report in the official journal of the World Water Council, concluded that the flooding during Katrina "could have been prevented had the corps retained an external review board to double-check its flood-wall designs". Other factors may have contributed to the flooding. According to the authors of ''Catastrophe in the Making'' (Island Press, 2009), the straight design and lack of outward flow into the Gulf allowed the

to become "the perfect shortcut for salt-water intrusion" which damaged buffering cypress forests and wetlands which historically had protected New Orleans from storm surge. The Army Corps of Engineers built and maintained the canal. Furthermore, according to storm surge researcher Hassan Mashriqui: The Corps of Engineers disputes these causalities. Nonetheless, in June 2008, the Army Corps of Engineers New Orleans District submitted a Deep-Draft De-authorization Study of the MRGO which stated that "an economic evaluation of channel navigation use does not demonstrate a Federal interest in continued operation and maintenance of the channel." Congress ordered the MRGO closed as a direct result. Many of the levees have been reconstructed since Katrina. In reconstructing them, precautions were taken to bring the levees up to modern building code standards and to ensure their safety. For example, in every situation possible, the Corps of Engineers replaced I-walls with T-walls, which have a horizontal concrete base that protects against soil erosion underneath the flood walls. Funding battles continue over the remaining levee improvements. In February 2008, the Bush administration requested that the state of Louisiana pay about $1.5 billion of an estimated $7.2 billion for Corps of Engineers levee work (in accordance with the principles of local cost-sharing required by Congress as early as the

Media involvement

Many representatives of the news media reporting on the aftermath of Hurricane Katrina became directly involved in the unfolding events, instead of simply reporting. Because of the loss of most means of communication, such as land-based and cellular telephone systems, field reporters in many cases became conduits for information between victims and authorities. The authorities, who monitored local and network news broadcasts, as well as internet sites, would then attempt to coordinate rescue efforts based on the reports. One illustration was when

. The role of AM radio was also of importance to the hundreds of thousands of persons with no other ties to news, providing emergency information regarding access to assistance for hurricane victims. Immediately after Katrina, WWL-AM was one of the few area radio stations in the area remaining on the air. This emergency service, simulcasted on shortwave outlet WHRI, was named " United Radio Broadcasters of New Orleans". Their ongoing nighttime broadcasts continued to be available up to away. Announcers continued to broadcast from improvised studio facilities after the storm damaged their main studios. The cellular phone antenna network was severely damaged and completely inoperable for several months. The storm also brought a dramatic rise in the role of websites—especially blogging and community journalism. One example was the effort of ''NOLA.com'', the web affiliate of New Orleans's '' Times-Picayune''. A group of reporters were awarded the Breaking News

and shared the Public Service Pulitzer with the Biloxi-based '' Sun Herald''. The newspaper's coverage was carried for days only on NOLA's blogs, as the newspaper lost its presses and evacuated its building as water rose around it on August 30. The site became an international focal point for news by local media, and also became a vital link for rescue operations and later for reuniting scattered residents, as it accepted and posted thousands of individual pleas for rescue on its blogs and forums. NOLA was monitored constantly by an array of rescue teams—from individuals to the Coast Guard—which used information in rescue efforts. Much of this information was relayed from trapped victims via the SMS functions of their cell phones, to friends and relatives outside the area, who then relayed the information back to NOLA.com. The aggregation of community journalism, user photos, and the use of the internet site as a collaborative response to the storm attracted international attention and was called a watershed moment in journalism. In the wake of these online-only efforts, the Pulitzer Committee for the first time opened all its categories to online entries. As the U.S. military and rescue services regained control over the city, there were restrictions on the activity of the media. On September 9, the military leader of the relief effort announced that reporters would have "zero access" to efforts to recover bodies in New Orleans. Immediately following this announcement, CNN filed a

From a September 2015 journal of ''Current Psychology'', a study examined the attitudes of older, long-term residents of Baton Rouge, Louisiana toward displaced newcomers to their community. After using multiple tests, analyses, and descriptive statistics, the study suggested residents grew to become more patient, tolerant, and friendly towards newcomers. The study also suggests, however, that residents felt more fearful and suspicious of the evacuees, as well as the fact that they were being taken advantage of more.


Reconstruction

Reconstruction of each section of the southern portion of Louisiana has been addressed in the Army Corps LACPR (Louisiana Coastal Protection and Restoration) Final Technical Report, which identifies areas to not be rebuilt and areas where buildings need to be elevated. The Technical Report includes: * locations of possible new levees to be built * suggested existing levee modifications * "Inundation Zones", "Water depths less than 14 feet, Raise-In-Place of Structures", "Water depths greater than 14 feet, Buyout of Structures", "Velocity Zones" and "Buyout of Structures" areas for five different scenarios. The U.S. Army Corps of Engineers submitted the report to the U.S. Congress for consideration, planning, and response in mid-2009.
