Redlining in New Orleans: Maps, Katrina, and Lasting Costs

Redlining in New Orleans refers to the federal practice, beginning in the late 1930s, of grading the city’s neighborhoods by perceived mortgage risk and steering lenders away from those with Black residents. The color-coded maps drawn by the Home Owners’ Loan Corporation pushed Tremé, the Seventh Ward, and the Lower Ninth Ward into the lowest category while lakeside and Uptown areas received the top grades. Those lines shaped which neighborhoods got investment, which homes survived Hurricane Katrina, and who could afford to come back.

Which New Orleans Neighborhoods Were Redlined

HOLC surveyors graded every residential block on a four-tier scale. Grade A (green) meant “best,” Grade B (blue) meant “still desirable,” Grade C (yellow) meant “definitely declining,” and Grade D (red) meant “hazardous,” a signal to lenders to refuse mortgages or lend only on the most conservative terms.1Mapping Inequality. Mapping Inequality – Redlining in New Deal America

The criteria went well beyond building condition. Surveyors noted the age of the housing stock and proximity to industry, but the racial and ethnic makeup of a block weighed heavily in the grade. Any concentration of Black residents pushed a neighborhood into the lowest categories regardless of the homes’ physical condition or the residents’ finances. The written “area descriptions” that accompanied each map were often blunt about race as the deciding factor.

Tremé, the Seventh Ward, and the Lower Ninth Ward all received D grades. Tremé and the Seventh Ward were flagged for their dense African American populations and older architecture. The Lower Ninth Ward’s modest wood-frame cottages and its perceived lack of modern infrastructure drew similar treatment. A D grade effectively locked residents out of the conventional mortgage market, making it harder to buy, renovate, or maintain a home.

Parts of the Garden District and Lakeview landed in the A and B categories. The Garden District drew praise for its large estates and the wealth of its residents. Lakeview, then rapidly developing, was favored for newer construction and a racially homogenous population. HOLC files for those areas emphasized stability and the absence of what surveyors called “detrimental influences.” The message to lenders was to invest lakeside, not riverside, and that pattern held for decades.

The Federal Housing Administration compounded the damage. Its 1938 Underwriting Manual explicitly warned against the “infiltration of inharmonious racial groups” and recommended racially restrictive covenants to protect property values.2Federal Reserve History. Redlining Federal mortgage insurance was tied to racial homogeneity, so segregation carried the force of federal policy.

How Katrina Turned Redlining Into a Recovery Gap

Decades without investment did not just restrict credit. They shaped the physical resilience of entire neighborhoods. Housing stock, drainage, and levee protections in redlined areas deteriorated over generations, and many of those neighborhoods sat below sea level behind inadequate levees. When Hurricane Katrina struck in 2005, the areas with the highest percentages of Black residents suffered the greatest housing destruction.

The federal recovery effort deepened the disparity. Louisiana’s Road Home program offered homeowners up to $150,000 in rebuilding grants but capped each grant at whichever was lower: the pre-storm property value or the cost of repairs. That formula punished Black homeowners in formerly redlined neighborhoods, where decades of disinvestment had depressed property values well below those in white neighborhoods. Two homes with identical repair costs could receive very different grants based on which side of an old HOLC line they sat on. Black homeowners were far more likely to receive grants pegged to the lower pre-storm value rather than actual rebuilding costs.3NAACP Legal Defense Fund. Case – Road Home

The return rates followed the same pattern. By the end of the first year after Katrina, roughly 70 percent of the city’s long-term white residents had returned, compared with 42 percent of long-term Black residents. Between 2000 and 2018, New Orleans’ Black population fell from 67 percent to 59 percent of the city, a net loss of more than 90,000 people.

Some formerly redlined neighborhoods then became targets for reinvestment, but on terms that displaced remaining residents. Tremé, the Bywater, and parts of the Seventh Ward saw declining poverty rates and shrinking shares of Black residents after the storm. The share of New Orleans renters spending more than half their income on housing rose from 24 percent in 2004 to 37 percent by 2018. Homeowners who held on watched values rise along with property taxes and insurance costs.

What Redlining Still Costs New Orleans Residents

The maps were retired long ago, but the geography of lending has been slow to change. Home Mortgage Disclosure Act data consistently shows Black mortgage applicants facing denial rates roughly double those of white applicants with comparable income profiles.4Consumer Financial Protection Bureau. Home Mortgage Disclosure Act (HMDA) Data Research has found that most of the gap remains unexplained by standard underwriting factors such as income, loan-to-value ratios, and debt levels.

In New Orleans, the homeownership gap is stark. As of 2024, 48 percent of Black householders in the city owned their homes, compared with 60 percent of white householders. Borrowers in historically underinvested census tracts also tend to pay higher interest rates and receive high-cost loans more often, increasing the long-term expense of owning a home in neighborhoods that can least afford it. These patterns track the old HOLC boundaries closely.

Appraisals add another layer. Homes in majority-Black neighborhoods have been shown to appraise lower than comparable homes in white neighborhoods, reducing the equity owners can build and the loan terms they can access. The federal Property Appraisal and Valuation Equity (PAVE) Task Force was launched in 2021 to address appraisal bias, but HUD effectively disbanded it in July 2025, rescinding the expanded borrower-initiated Reconsideration of Value process and related guidance. Federal fair housing enforcement authority remains intact, but the dedicated institutional focus on appraisal equity is gone for now.

Reverse Redlining

Where old redlining excluded neighborhoods from credit, reverse redlining targets those same neighborhoods with exploitative loans: inflated interest rates, hidden fees, balloon payments, and prepayment penalties designed to maximize lender profit and increase the odds of default. The pattern exploits the very credit gap the original maps created, turning long-underserved residents into a captive market for subprime products.

Health and Environmental Consequences

Redlining’s damage reaches beyond housing finance. Research comparing formerly A-graded and D-graded census tracts nationally has found life expectancy as low as 68 years in D-graded areas versus 86 years in A-graded ones. Asthma rates are nearly double, diabetes prevalence more than twice as high, and high blood pressure affects 47 percent of residents in formerly redlined areas versus 31 percent in historically green-graded ones.5Mapping Inequality. Redlining and Health Neighborhoods starved of investment got fewer parks, less tree canopy, and more industrial facilities, and formerly redlined areas experience significantly higher urban heat intensity. In a city where summer heat and humidity are already extreme, that translates into higher medical costs and shorter lives.

Laws That Now Prohibit Redlining

The Fair Housing Act, Title VIII of the Civil Rights Act of 1968, makes it illegal to refuse to sell, rent, or finance a home because of race, color, religion, sex, familial status, national origin, or disability.6Office of the Law Revision Counsel. 42 USC 3604 – Discrimination in the Sale or Rental of Housing The prohibition covers not just outright denials but worse loan terms, steering applicants toward certain neighborhoods, or discouraging applications in the first place.7National Credit Union Administration. Fair Housing Act (FHA)

The Community Reinvestment Act addresses the neighborhood-level side of the problem. It requires federal banking regulators to evaluate how well financial institutions meet the credit needs of the communities where they operate, including low- and moderate-income neighborhoods.8Office of the Law Revision Counsel. 12 USC 2903 – Financial Institutions’ Record of Meeting Community Credit Needs Poor CRA performance can block a bank’s applications to open branches, merge, or expand. A major overhaul of CRA evaluation rules took effect on January 1, 2026, modernizing how regulators assess lending records and requiring more granular data on lending in underserved areas.9Office of the Comptroller of the Currency. Community Reinvestment Act – Supplemental Final Rule

Louisiana adds its own layer through the Louisiana Equal Housing Opportunity Act at La. R.S. 51:2601.10Louisiana State Legislature. Louisiana Code RS 51:2601 – Title The state statute mirrors the federal Fair Housing Act’s prohibitions and extends protection to natural, protective, or cultural hairstyle, meaning a landlord or lender cannot discriminate based on how a person wears their hair.

How to File a Housing Discrimination Complaint in New Orleans

Anyone who believes a lender, landlord, or real estate agent has discriminated against them can file a complaint with HUD’s Office of Fair Housing and Equal Opportunity. The complaint must be filed within one year of the last discriminatory act.11U.S. Department of Housing and Urban Development. Learn About FHEO’s Process to Report and Investigate Housing Discrimination HUD will interview you, draft a formal allegation, and notify the accused party. An investigator then collects evidence, takes witness statements, and may conduct site inspections.

HUD attempts to broker a voluntary settlement throughout the investigation. If none is reached and HUD finds reasonable cause to believe discrimination occurred, it issues a formal charge. Both sides then have 20 days to decide whether to take the case to federal court. If neither side elects a federal trial, a HUD administrative law judge hears the case. Remedies can include compensation for out-of-pocket losses and emotional distress, injunctions against future discrimination, attorney’s fees, and civil penalties.11U.S. Department of Housing and Urban Development. Learn About FHEO’s Process to Report and Investigate Housing Discrimination

You can also skip HUD and file a private lawsuit in federal or state court. The deadline for a private suit is two years from the last discriminatory act, and any time spent in a pending HUD proceeding does not count against that clock.12Office of the Law Revision Counsel. 42 USC 3613 – Enforcement by Private Persons If HUD has already filed a charge, the Department of Justice can bring the case to court on your behalf at no cost.
