Katrina: What the Flood Revealed

New Orleans sits below sea level — a geological fact that was managed for decades by a levee system built and maintained by the Army Corps of Engineers. After Hurricane Betsy flooded the Lower Ninth Ward in 1965, Congress authorized a comprehensive levee improvement project. The project was never completed. Budget cuts during the 1970s, 1980s, and 1990s left critical sections of the levee system below the design specifications needed to withstand a Category 3 hurricane, which was the standard the project was meant to achieve.

In 2001, FEMA ranked a major hurricane striking New Orleans as one of the three most likely catastrophic disasters facing the United States — alongside a terrorist attack on New York and a major earthquake in San Francisco. In 2004, a federal exercise called Hurricane Pam simulated exactly the scenario that occurred in 2005: a major hurricane, levee failures, mass flooding. The simulation predicted that over 60,000 people would die and over 1 million would be displaced. The recommendations from that exercise had not been implemented when Katrina struck 13 months later.

The levee sections that failed — the 17th Street Canal, the London Avenue Canal, and the Industrial Canal near the Lower Ninth Ward — failed not because they were overtopped by storm surge but because they were structurally inadequate. The Army Corps of Engineers later acknowledged this in a 2006 report. The levees failed before the water reached their design height. This was an engineering failure, not a natural disaster.

Mayor Ray Nagin issued a mandatory evacuation order for New Orleans on August 28, 2005, the day before Katrina made landfall. The order was the right call. The problem was that the evacuation plan — the Contraflow system that reversed highway lanes to facilitate outward traffic — was designed for people who owned cars. According to the 2000 Census, 27% of New Orleans households had no vehicle. In the Lower Ninth Ward, that figure was higher. The population without cars was disproportionately Black, elderly, disabled, and poor.

The Superdome and Convention Center were designated as "shelters of last resort." No adequate food, water, medical care, or security planning was in place at either location. Approximately 30,000 people sheltered at the Superdome; another 20,000 at the Convention Center. Both became scenes of humanitarian crisis that were broadcast globally for days while the federal government debated whether to respond. People died waiting for water in 95-degree heat at the Convention Center while the Director of FEMA — Michael Brown — told reporters he had only just learned there were people there.

Hurricane Katrina made landfall on August 29. The levees failed the same day. By August 30, 80% of New Orleans was flooded. Photographs and news footage of people stranded on rooftops, wading through contaminated water, and dying in the Convention Center were broadcast worldwide. President George W. Bush remained at his ranch in Crawford, Texas until August 31, when he flew back to Washington — not to New Orleans. He did not visit New Orleans until September 2. He praised FEMA Director Brown on camera: "Brownie, you're doing a heck of a job."

The National Guard troops, water, food, and medical supplies that eventually arrived did so five days after the levees failed. The congressional investigations that followed documented a systematic failure of federal emergency management: FEMA had been downgraded within the Department of Homeland Security post-9/11, losing budget, staff, and access; its director was a political appointee with no emergency management experience; pre-positioned supplies were inadequate; and communication between local, state, and federal levels broke down completely.

The St. Bernard, Lafitte, C.J. Peete, and B.W. Cooper housing developments — the four major public housing projects in New Orleans — survived Hurricane Katrina with minimal flooding. Many units were intact and habitable. In the months following the storm, the Housing Authority of New Orleans, with federal approval and HUD funding, demolished all four developments and replaced them with mixed-income housing that contained significantly fewer units reserved for low-income residents.

The total number of public housing units in New Orleans went from approximately 5,100 before Katrina to fewer than 2,000 by 2010. The demolished units had housed approximately 15,000 people, nearly all Black. The mixed-income replacements housed far fewer, at higher rents, with eligibility requirements (credit checks, employment requirements, drug testing) that excluded many former residents. The demolitions were carried out over the explicit protests of former residents and housing advocates, some of whom were arrested attempting to attend public hearings.

City Councilwoman Stacy Head, one of the few white members of the city council, described the demolitions as an opportunity to prevent "the criminal element" from returning. The "criminal element" she was describing was the Black low-income population that had lived in public housing. Her framing was unusually explicit; the intent behind the demolitions — permanent Black displacement — was the consistent policy outcome regardless of the language used to describe it.

Before Katrina, the New Orleans public school system was underfunded and underperforming — a consequence of decades of disinvestment documented in this archive. In the weeks after the storm, the Louisiana state legislature voted to take over the New Orleans school system and place most of its schools under the control of a new Recovery School District, which converted them to charter schools. The Orleans Parish School Board simultaneously fired all 7,500 teachers and staff — the largest mass firing of public employees in American history — ending their union contracts and benefits.

The reconstitution of New Orleans schools as a charter system has been studied extensively, with contested results. Test scores did improve over the following decade, and some charter schools produced strong outcomes. What is not contested: the firing of all teachers disproportionately affected Black educators who made up approximately 71% of the pre-Katrina teaching force; teachers who wanted to return had to reapply without seniority, often to charter organizations with higher expectations of hours and lower pay; and the new system had significantly less Black administrative leadership than the pre-Katrina system. The reconstitution used the disaster to accomplish a restructuring of public education that had been pursued unsuccessfully for years before the storm.

The Road Home program — the primary federal mechanism for compensating Louisiana homeowners for Katrina damage — was administered by the Louisiana Recovery Authority and funded by $11.5 billion in federal Community Development Block Grant funds. The program used a formula that calculated compensation based on the lower of either (a) the cost of damage or (b) the pre-storm market value of the property. Because property values in Black neighborhoods had been suppressed by decades of redlining, disinvestment, and discriminatory appraisal practices, Black homeowners consistently received less compensation than white homeowners for equivalent storm damage.

A class action lawsuit — filed by the Greater New Orleans Fair Housing Action Center — documented this disparity with data: Black homeowners received on average $8,000 less than white homeowners for the same level of damage. The lawsuit was settled in 2011; the state agreed to recalculate awards and provide additional compensation. By that time, many displaced Black homeowners had already made permanent decisions — selling their flooded properties at distressed prices, relocating to Houston or Atlanta, and not returning. The settlement came too late to reverse the displacement it had documented.

On September 1, 2005 — three days after Katrina — approximately 200 New Orleans residents, most of them Black, attempted to walk across the Crescent City Connection bridge to Gretna, Louisiana, a predominantly white suburb on the west bank of the Mississippi. Gretna police, along with Jefferson Parish Sheriff's deputies, blocked the bridge with armed officers and turned the evacuees back at gunpoint. When the crowd grew to approximately 2,000 people the next day, police fired shotguns over their heads to disperse them. People who had walked miles through flooded streets seeking any path to safety were blocked from crossing a bridge by law enforcement who described their action as protecting their community.

Gretna Police Chief Arthur Lawson defended the decision: "We're not going to have people coming over here and causing our people any concern." The Governor of Louisiana called the incident "extremely unfortunate." No charges were filed. The incident was documented in video and survivor testimony and became a nationally discussed symbol of the racial dynamics of the Katrina response — a literally visible barrier placed by white law enforcement between Black disaster survivors and safety.

New Orleans' population has largely recovered numerically — it stood at approximately 383,000 in 2023, still below the pre-Katrina 484,000 but significantly recovered from the 2010 low. The city's economy, centered on tourism and hospitality, has in many ways prospered. The school system, while contested, has improved some metrics. The flood protection system was rebuilt and significantly upgraded after Katrina — the $14.5 billion Hurricane and Storm Damage Risk Reduction System, completed by 2011, is substantially more robust than the levees that failed.

What the numbers show that prosperity claims do not: the city is less Black than before Katrina; the Black homeownership rate in neighborhoods like the Lower Ninth Ward has not recovered; the public housing stock has not been rebuilt; and the workforce that staff the tourism economy is paid wages that do not support living in a city whose gentrification Katrina accelerated. The people who rebuilt New Orleans — many of them Latino immigrants who arrived in the aftermath — were often paid below minimum wage by contractors exploiting post-disaster labor conditions, in a city where OSHA compliance was suspended in the emergency period.

The pattern Katrina documents is the pattern this archive traces in every chapter: a community made vulnerable by prior policy, struck by disaster or destruction, abandoned in the immediate crisis, and then displaced by the "recovery" that follows. The disaster is the mechanism; the displacement is the outcome; the prior policy is the cause. Katrina was not exceptional. It was the most documented recent example of a recurring structure.
