New Orleans Now After Katrina: Levees, Housing, and Schools

Twenty years after Hurricane Katrina made landfall on August 29, 2005, New Orleans is both remarkably rebuilt and still visibly broken. The city has poured billions into flood defenses, rebuilt its tourism economy, overhauled its schools, and watched violent crime fall three years in a row. It is also smaller, poorer for many of the people who returned, squeezed by an insurance crisis and crumbling water pipes, and missing entire neighborhoods that never came back. The recovery of New Orleans after Katrina, 20 years later, has been described in one assessment as simply “uneven.”¹

A Smaller, Whiter, More Expensive City

Before Katrina, roughly 485,000 people lived in Orleans Parish. The 2025 Census Bureau estimate puts the population at about 362,000, or roughly 75% of what it was before the storm.²³⁴

Those losses fall heavily along racial lines. In 2000, about 325,000 Black residents made up 67% of the city. By 2024, that number had fallen to roughly 204,000, or 57%, a net loss of more than 120,000 Black residents. White residents also declined, but by only about 23,000.⁵ Researchers have found that displaced Black adults were more likely to have relocated to Texas, elsewhere in Louisiana, and other Southern states, and less likely to return.⁶ The barriers included lack of a car, higher post-redevelopment housing costs, flood exposure, and destroyed social networks.⁷

The city is also stratifying by income. Between 2019 and 2023, New Orleans had a net loss of more than 9,000 households earning under $25,000 a year and a net gain of more than 10,000 households earning over $100,000.⁴

Levees That Hold Now, but Not Forever

The most visible legacy of the federal response is the Hurricane and Storm Damage Risk Reduction System, a $14.6 billion network of 350 miles of levees, floodwalls, gates, and pumping stations ringing metro New Orleans.⁸ It includes the Lake Borgne Surge Barrier, the largest structure of its kind in the world, and the GIWW-West Closure Complex, the largest drainage pump station.⁹ The last major piece was finished in 2018, and the Army Corps calls the system “stronger and better than it has ever been.”¹⁰

The system was built to protect against a storm with a 1-in-100 annual chance, and only through 2057. Weak soils, subsidence, and sea-level rise are already lowering the levees. The Corps estimates that keeping protection adequate over the next 50 years will cost another $1.1 billion, including lifting 50 miles of levees and adding new floodwalls. Without those investments, the system is projected to drop below the 100-year standard by 2073, which could disqualify the region from the National Flood Insurance Program.⁸

The Coast Is Still Disappearing

Levees address storm surge. They do not address the land itself vanishing. Louisiana has lost more than 2,000 square miles of coast since 1932, and sea-level rise projections for the region range from one to 4.6 feet by 2100.¹¹ Without intervention, models predict 1,100 to 3,000 additional square miles of land loss, exposure for more than two million residents, and $15 billion in annual storm damage.¹²

The state’s response is the Coastal Master Plan, a 50-year, $50 billion strategy updated every six years. Since 2005, Louisiana has spent $21.4 billion and finished more than 140 projects, including restoring nearly all its barrier islands and improving 369 miles of levees.¹³ The 2023 edition adds 73 projects and puts $11.2 billion toward nonstructural measures like home elevations and buyouts, an acknowledgment that some places cannot be saved. Much of the current funding comes from the 2010 Deepwater Horizon settlement, which is expected to run dry within a decade.¹²

Water and Drainage Are Falling Apart

Under the rebuilt streets, the water and drainage system is in serious trouble. The Sewerage and Water Board of New Orleans manages roughly 1,600 miles of water mains, more than a third of which are over 100 years old. In 2025, the system lost 72% of its treated water, or 38.8 billion gallons, to leaks and breaks.¹⁴¹⁵ Six major mains broke in the first five months of 2026, flooding streets and triggering boil water advisories.

The drainage side has its own quirk. Many pumps run on 25-hertz electricity, a frequency no power utility provides, so for over a century the Sewerage and Water Board generated its own using steam turbines, some dating to 1915. Repeated failures left parts of the city unable to pump floodwater during heavy rain. A new $280 million power substation, the West Power Complex, came online in December 2025, drawing power from Entergy and converting it to the frequency the old pumps need. The old turbines now serve as backup.¹⁶

The pipes themselves are the larger problem. Since Katrina, only about 115 miles of water mains — 7% of the total — have been replaced using federal funds. The agency’s long-term plan calls for replacing 60% of the system over 20 to 30 years at costs scaling up to $2 billion, but Executive Director Randy Hayman has said the agency currently lacks the money even for the immediate high-priority repairs, estimated at $3 million.¹⁴

The Insurance and Housing Squeeze

Even for homeowners who rebuilt, staying has gotten expensive. Homeowners insurance premiums in New Orleans rose an average of 78% over the five years leading up to August 2025, and National Flood Insurance Program premiums rose an average of 102%, with some ZIP codes hit with increases up to 303%.¹⁷ Standard homeowners policies in Louisiana rose 43% between 2021 and 2024 alone.⁴ Between 2021 and 2023, a dozen insurers operating in the state were declared insolvent.

More than 58,000 New Orleans households now spend more than 30% of their income on housing. For the lowest-income residents, energy costs alone consume a fifth to a quarter of income.⁴

Neighborhoods That Never Came Back

The tourist-facing parts of the city — the French Quarter, the Garden District, Uptown — look fine, often better than before. In the Lower Ninth Ward, the damage is still visible. Levee breaches there rendered 100% of homes uninhabitable.¹⁸ Twenty years later, the neighborhood’s population is about a third of the pre-Katrina 15,000, with boarded homes, overgrown lots, and blocks holding few houses or people.¹⁹

A handful of businesses have opened, including a produce market run by the nonprofit Sankofa, which is also turning vacant lots into vegetable gardens to address the neighborhood’s status as a food desert. The former Holy Cross High School has been converted into apartments. There is no systematic government redevelopment plan, and the path back is blocked by property disputes, tax liens, and speculators holding blighted lots. The Port of New Orleans has approved a grain terminal with rail lines running through the neighborhood, a project some residents fear will discourage return.¹⁹

Elsewhere, gentrification has reshaped formerly working-class areas. Bywater has been called “gentrification ground zero,” with average home prices reaching $386 per square foot, roughly double the rates in the Upper and Lower Ninth Ward.²⁰ Research has found that post-Katrina gentrification tracked closely with ground elevation: higher, lower-income neighborhoods drew the biggest influx of wealthier, whiter residents, a pattern scholars call “climate gentrification.”²¹

Public Housing Demolished and Replaced with Less

One of the most contentious chapters of the recovery was the demolition of the city’s four largest public housing developments — Lafitte, St. Bernard, B.W. Cooper, and C.J. Peete — collectively known as the “Big Four.” HUD determined the buildings were structurally sound after cleaning but authorized demolition rather than renovation, which was estimated to cost over $1 billion.²²²³

More than 4,500 units were torn down starting in 2008 and replaced with mixed-income developments: Faubourg Lafitte, Columbia Parc at the Bayou District, Harmony Oaks, and Marrero Commons. Only about 700 of the replacement units were designated as public housing apartments. Citywide, public housing units dropped from over 5,000 before the storm to 1,900 by 2015, while Housing Choice Vouchers doubled to 17,632. As of that date, the waiting list for subsidized housing held 16,000 families and had been closed for years.²⁴ Former residents with vouchers often ran into credit-score barriers, landlord discrimination against Section 8 holders, and new utility costs that had been included in their previous rent.

The Road Home Program’s Racial Disparities

The largest housing recovery effort was the Road Home program, a $10 billion initiative that became the biggest of its kind in U.S. history. Grants were capped at the lesser of a home’s pre-storm value or estimated repair costs, up to $150,000. That formula built in a structural disadvantage for owners in poor, predominantly Black neighborhoods, where rebuilding costs routinely exceeded appraised home values. In the poorest areas, homeowners had to cover an average of 30% of their own rebuilding costs after all aid; in wealthier areas, that gap was 20%.²⁵

The NAACP Legal Defense Fund sued HUD and the Louisiana Recovery Authority on behalf of more than 20,000 families, alleging the formula violated the Fair Housing Act.²⁶ A court blocked the formula in 2010 and issued an injunction. HUD now prohibits disaster recovery grants that compensate based on home values, requiring states to reimburse actual approved repair expenses instead.²⁵

An Economy Back on Paper, Fragile in Structure

The metro economy still leans heavily on tourism, oil and gas, shipping, and petrochemical manufacturing, sectors that have collectively shed 38% of their jobs since 2004, largely to automation. The region has 10% fewer jobs than in 2000. Newer industries — environmental services, water management, video production, performing arts — have emerged, but they tend to pay well below national averages. Performing arts jobs in the metro area average $43,603, compared to $77,903 nationally.³

Tourism has nearly caught back up to pre-pandemic levels. About 19.4 million visitors spent roughly $10.8 billion in the city in 2025, close to the 2019 peak of 19.75 million visitors and $10.5 billion in spending.²⁷²⁸ Hospitality employs over 80,000 people. Hotel occupancy is still about 10 percentage points below the 2019 peak, and the jobs pay low wages. Louisiana still follows the $7.25 federal minimum wage, and as of 2022, 39% of workers statewide earned less than $15 an hour, rising to 58% for Black workers.²⁹

Entrepreneurship is a bright spot. The metro’s startup rate runs about 35% above the national average, and between 2017 and 2022, Black-owned businesses with employees grew faster in the region than any other racial or ethnic group. The poverty rate has come down from 28% in 2000 to roughly 20-23%, still nearly double the national figure. The racial wealth gap is enormous: white households in the metro hold about 10 times the wealth of Black households.³⁰

Schools Rebuilt as a National Experiment

Katrina destroyed or damaged 110 of 126 school buildings. The state took control of nearly all of the city’s schools, fired every educator, let the union contract expire, and eliminated attendance zones. Over the next 13 years, every school became an autonomous charter run by an independent nonprofit, the most sweeping district overhaul any American city has undergone.³¹

During the first decade, average student test scores rose by 11 to 16 percentiles, graduation rates climbed from 56% to roughly 80%, and college entry rates rose by 8 to 15 percentage points.³² Tulane researcher Doug Harris described the shift as moving the system “from an F to a C.” Outcomes peaked around 2013 and have since plateaued, and board members now acknowledge the district cannot “close our way to improvement.”

The overhaul carried human costs. Teacher turnover nearly doubled, the share of Black teachers fell from 71% in 2005 to 49% by 2014, administrative spending rose 66% while instructional spending fell 10%, and student commute distances increased by at least two miles.³¹ Enrollment has dropped from over 65,000 to fewer than 44,000, tracking the city’s population loss. The system is now reunified under a local school board, and in fall 2024, the district opened its first directly operated school since the storm, the Leah Chase School.³²

Healthcare Rebuilt, Outcomes Still Last

Katrina shut down 13 of 16 area hospitals. The most iconic was Charity Hospital, the public safety-net facility that had served the city’s poor since 1736. It never reopened. In its place, University Medical Center New Orleans opened in 2015 under LCMC Health, providing acute care for the region.³³ The new facility proved itself during Hurricane Ida in 2021, when it ran off the grid for 11 days.³⁴

The broader model shifted from emergency-room dependence to community-based care. Federally qualified health centers in Louisiana grew from about 45 before the storm to more than 260 by 2025. Louisiana’s 2016 Medicaid expansion under the Affordable Care Act had covered more than 133,000 New Orleans residents by 2023, about 36.5% of the city.³⁴ Louisiana still ranks 50th among states in overall health outcomes, the same rank it held before the storm.

Crime Is Falling, but Politically Contested

After years as one of the country’s most violent cities, New Orleans saw violent crime fall for the third straight year in 2025. Murders dropped from 266 in 2022 to 121 in 2025, a figure that includes the 14 people killed in the January 1, 2025, Bourbon Street vehicle-ramming attack.³⁵ Through the first quarter of 2025, overall violent crime was down 20% year over year, with fatal shootings down 28% and nonfatal shootings down 27%.³⁶

The decline mirrors a national trend since the COVID-era spike. Local officials also point to a joint intelligence group with ATF and Homeland Security Investigations that produced over 100 arrests after August 2024. The department remains understaffed at about 910 officers. In early 2026, 350 National Guard members were deployed to the French Quarter at the request of Governor Jeff Landry, who cited “elevated violent crime rates,” a characterization that clashed with the actual downward trend in the data.³⁵

Culture Has Come Home

The storm scattered the city’s culture-bearers, and their return became inseparable from the physical rebuilding. Preservation Hall’s Ben Jaffe founded the New Orleans Musicians Hurricane Relief Fund to help local artists come home.³⁷ The restaurant scene grew from about 800 establishments before the storm to over 1,200 by 2018, with the city favoring independent operators over chains. The Dew Drop Inn Hotel and Lounge, a historic venue where Ray Charles and Little Richard once performed, reopened in February 2024.³⁸ Dooky Chase’s Restaurant, a pillar of Creole cuisine for eight decades, received the 2025 James Beard America’s Classics award. Community radio station WWOZ continues to serve as a hub for musical preservation.

The Mental Health Toll Persists

Among low-income, predominantly Black parents in New Orleans, the prevalence of serious mental illness doubled in the year and a half after the storm, and nearly half showed symptoms of probable PTSD.³⁹ A separate study of a broader sample found suicidal ideation more than doubled and that, unusually for post-disaster populations, mental health outcomes worsened rather than improved over time. Researchers attributed most of the increase to unresolved storm-related stressors: ongoing displacement, property loss, disrupted social networks.⁴⁰

The Federal Backstop Is Being Pulled Back

The failures of the Katrina federal response — botched evacuations, days-long waits for rescue, a FEMA director with no emergency management experience — produced sweeping reforms in 2006. The Post-Katrina Emergency Management Reform Act strengthened FEMA, required its administrator to have professional disaster experience, and gave the agency authority to deploy resources before a formal request for help. In 2018, Congress created a dedicated fund for preparedness projects like floodwalls and warning systems.⁴¹

Those reforms are now being reversed. The Trump administration announced in June 2025 its intention to eliminate FEMA entirely, and an executive order established a review council to evaluate the agency’s future.⁴² DHS Secretary Kristi Noem imposed a policy requiring her personal approval for all FEMA expenditures over $100,000, and the administration has canceled major disaster preparedness grant programs. The acting FEMA administrator as of mid-2025 had no emergency management experience, precisely the problem the 2006 law was written to prevent.⁴¹

For New Orleans, the stakes are direct. Between 2015 and 2024, Louisiana residents received $53 million in direct FEMA assistance through the Individuals and Households Program, the highest of any state.⁴³ A city spokesperson said New Orleans relies “highly” on federal funding for post-disaster recovery and that the city government is too small to absorb the loss. Urban Institute analysis found that if the proposed federal funding reductions had been in place in 2020 and 2021, Louisiana would have lost an estimated $592 million and $768 million respectively, amounts that would have far exceeded the state’s rainy-day funds.⁴⁴ Since 2020, every parish in the New Orleans metro has experienced at least 17 declared disasters, four times the national average.³⁰
