The charges of racism that swirled after Hurricane Katrina devastated New Orleans 12 years ago have yet to surface as Houston recovers from the floods unleashed by Harvey.

Houston was hit as the nation roiled from a white supremacist rally that turned deadly Aug. 12 in Charlottesville, Virginia. The violence left in its wake deep divisions primed by President Donald Trumpโ€™s assertion that โ€œmany sidesโ€ were to blame, producing heated debates about Confederate statues and whether they are important historical markers or symbols of hate that should be removed.

When Katrina struck on Aug. 29, 2005, New Orleans had 500,000 residents, nearly 70 percent of them Black. Americans were horrified by images of people stranded on rooftops and scrounging for food and water. There were appalling conditions in the Superdome, the shelter of last resort for thousands and a hell-scape for those too poor to leave ahead of the storm.

The face of Katrina was largely Black and poor. Within days, Katrinaโ€™s death toll was into the hundreds. By contrast, Harveyโ€™s death toll hovered around 60, though itโ€™s expected to rise as waters recede.

Many cited the heavy death toll following Katrina, and the slow, inadequate government response, as evidence that New Orleansโ€™ poor, Black residents were considered disposable.

By comparison, Houston โ€” a sprawling city of more than 2.4 million โ€” is more racially diverse, with Blacks and whites each accounting for about a quarter of the population. Because there was no mandatory evacuation, people of all races and classes remained in the stormโ€™s path, not just folks who couldnโ€™t afford to leave.

That made for diverse images in the scenes of boat rescues and families huddling in shelters, said New Orleans native Mtangulizi Sanyika, a retired professor and social activist who left his New Orleans neighborhood the day before Katrina hit and now lives in Houston.

โ€œWhat weโ€™re not seeing in Houston are the hundreds of Black people being stuck in a building or stopped on a highway and blocked from getting out of the city,โ€ said George Washington University sociologist Gregory Squires. โ€Nobody is saying that Donald Trump doesnโ€™t like Black people.โ€

In New Orleans, as the levees broke, the water rose and people struggled to survive as media reports of looting depicted storm victims as criminals. Those who were eventually able to relocate to other cities were labeled โ€œrefugees,โ€ a term usually reserved for people fleeing one country for another.

The narrative around Katrina was urban neglect โ€” years of disinvestment in infrastructure affecting a largely minority population. With Harvey, the focus is more on urban sprawl and how development may have compounded a natural disaster.

โ€œKatrina was kind of a crime scene, with implications against local, state and federal government on how they were failing poor people; in Houston, itโ€™s kind of universal,โ€ said Rice University historian Douglas Brinkley.

Devin Coleman, 34, moved to Houston from the Lower Ninth Ward in New Orleans just before Katrina hit. He lost his aunt and his grandmother in the storm. He was sheltered at Houstonโ€™s convention center for nearly a week and was amazed at how helpful people were.

โ€œIf you werenโ€™t white or had your own money, itโ€™s almost as if they didnโ€™t want you there.โ€ Coleman recalled of the environment during Katrina. โ€œIn Harvey, nobody is talking about race. Itโ€™s just, โ€˜What do you need?’โ€

Al Sistrunk, 67, echoed Colemanโ€™s sentiments, praising the cityโ€™s response to Harvey while waiting in line to file a Federal Emergency Management Agency.

โ€œHere in Houston, itโ€™s everybody,โ€ Sistrunk said. โ€œWeโ€™re getting housing, people are getting food, people are getting material they need for their houses. They rescued everybody, they werenโ€™t rescuing white people first or black people first, at least thatโ€™s what they show on the news.โ€

Texas Southern University urban planning professor Robert D. Bullard warned what happens next could uncover racial disparities.

Homeowners of color may lack the financial resources or networks to rebuild as quickly, if at all, he said. On the cityโ€™s more affluent and white west side, Bullard noted people are โ€œhiring contractors and starting to rebuild.โ€

Bullard, regarded as the father of โ€œenvironmental racism,โ€ also pointed out that poor and minority residents were most likely to have lived in proximity to the industrial areas affected by the storm. Pollution and chemical spills could affect those communities disproportionately.

Squires predicted as the scope of the damage is surveyed the racial impact will grow.

โ€œRich and poor alike were affected by the storm, but I strongly doubt that these groups were affected equally,โ€ he said. โ€œThe optics clearly are not as racial here as they were in New Orleans. But I think we need to distinguish between the optics and the reality.โ€
