Living on the edge of disaster 

By Miquéla V Thornton

As flooding becomes an increasingly common and destructive feature of Texas life, housing experts are calling for the creation of a statewide, voluntary buyout program to move residents out of the most high-risk areas.

The experts say Texas needs a bold and urgent solution as around 5 million people — one of the highest numbers among US states — live or work on floodplains, and climate change is bringing more intense rainfall. Galveston, Texas, for instance, now endures nearly 14 floods annually, a dramatic increase from virtually none in the 1950s.

“That’s why the buyout approach is necessary — it’s the only way to get existing structures out” of harm’s way, said Shannon Van Zandt, a housing equity researcher at Texas A&M University, who has advocated for a state plan.

Buyout programs usually involve a government purchasing a property that has repeatedly flooded at market rate to reduce resident risk, cut liabilities and restore land, which can improve flood resiliency. 

The call for state action comes as federal support for buyouts has proven increasingly unreliable. Historically, the Federal Emergency Management Agency (FEMA) covered most of the costs of buyouts, albeit with a slow process and requirements that leave out in-debt homeowners. Yet funding cuts and policy changes under the Trump administration have left some flood-stricken communities across the US in a “buyout limbo,” making a state-led initiative a potential necessity.

Some states — New Jersey, New York and Washington — have already launched permanent programs with non-federal funding, with others like Massachusetts exploring the option. Cities and counties are rolling out buyouts as well, including Tulsa, Nashville and Charlotte-Mecklenburg County in North Carolina and Austin and Harris County in Texas. New York City, meanwhile, plans to launch a program next year. 

What has made these programs successful are three things: their permanence, community buy-in and independent funding. Tulsa and Nashville officials have said the cities will entirely fund buyouts if necessary, until FEMA funding is restored.

More local control

Ivis Garcia, an urban planning expert at at Texas A&M, said Texas is in a strong economic position to introduce a statewide program because of its multi-billion-dollar rainy day fund, a state savings account for emergencies.

The fund had a budget surplus of $23.8 billion as of January. Texas’ rainy day fund is among the most robust in the US — a Pew Research Analysis showed it could survive solely on those funds for over 86 days, ranking no. 7 among states.

Jeff Branick, who has overseen buyouts in Jefferson County, Texas, said a well-funded state program would overcome many of the problems he’s experienced with federal grants. After Hurricane Harvey, for example, the county secured federal funding to offer buyouts to 100 homeowners in a heavily damaged subdivision. But because it took years for the money to flow into the county, about a third of homeowners chose not to participate. These homes remain at risk, he said, and the county, meanwhile, still has to pay to maintain the now more sparsely populated subdivision. 

“A state-run program with fewer restrictions and less administrative overhead would certainly be attractive to flood-prone areas,” Branick said, “but I’ll leave it to friends at the legislature to decide.”

Experts argue that buyouts can save money in the long run. The Natural Resources Defense Council calculates that for every $100 that has been spent via federal funds to rebuild a flood-destroyed home in the US, it costs only $1.70 to help move people before a disaster.

“Floods are inevitable; catastrophe is not,” said Tim Palmer, a former planner and author of the book Seek Higher Ground, which explores attempts to flee floodplains across the US.

Texas is still reeling from floods that killed more than 130 people last month and caused $18 billion to $22 billion in damage, according to early estimates.

Getting community buy-in

Despite the need to cover areas of the state without local buyout plans, experts note implementing a statewide program in a place as vast and diverse as Texas presents significant challenges. Buyouts are not just costly, but are also likely to face resistance from residents emotionally or financially tied to their homes.

Some of those barriers can be avoided if officials doing the buyouts involve community members from the start, said Linda Shi, a professor of city and regional planning at Cornell University.

Shi studied five local, long-term buyout programs in the US, and found successful initiatives focused on making communities emotionally prepared to leave their homes. It also helps to enlist residents in the buyout funding, for example, by adding a fee in their utility bill. That raises awareness about how these programs work and the need for them. 

“These events that used to be one in 100 [years] or one in 500 are happening back-to-back and that really wears down people’s finances … as well as their mental wherewithal,” she said.

What we learned this week

  1. Climate change is having an impact on beef prices. After years of drought, pastures haven’t been producing enough grass to feed cattle. So ranchers have been sending their animals to the slaughterhouse earlier, cutting back herds even as Americans eat more beef. This is sending prices to record highs.
  2. Hawaii is introducing a “green fee” to raise money for environmental projects. The state aims to raise some $100 million each year by marginally hiking tourism levies — from 10.25% to 11% — costing Hawaii’s 10 million annual tourists an average of $2 per day.
  3. Some common medications can increase the risk of heat-related illness. Certain drugs, including those for allergies and depression, can reduce the body's ability to sweat or cause it to sweat too much, according to the US Centers for Disease Control and the World Health Organization.
  4. Major consumer brands are trimming plastic packaging targets. Coca-Cola and Pepsi had both pledged to use 50% recycled material in their packaging by 2030. Now Coca-Cola is aiming for at least 35% by 2035, while Pepsi intends to meet a minimum of 40% by the same year. 
  5. Heat pump advertising is causing a kerfuffle in Britain. Two major heat pump installers, Aira UK and EDF Energy Ltd. have had adverts banned by a UK regulator for misleading consumers. The ruling on Wednesday follows a decision last week by the ASA to ban an ad from top UK electricity supplier Octopus Energy, which also promoted subsidies for heat pumps.

Worth your time

Green firms in the US have found something of a lifeline in artificial intelligence after being bogged down by high interest rates, shrinking funding and, more recently, President Donald Trump’s sharp rollback of support.

Clean technology companies that have inked deals to support data centers have seen their stocks soar this year, outperforming the S&P 500. Nuclear power startup Oklo Inc.’s shares are up nearly 275% year-to-date while the stock price of fuel cell provider Bloom Energy Corp. has risen 66%. Energy storage and clean power snagged the most public and private investment among climate tech sectors last quarter, according to BloombergNEF.

Yet the data center boom may prove short-lived for some carbon-free tech companies. While the age of AI is just starting, the ability of renewable firms to continue benefiting could be limited by a White House keen to boost fossil fuels and kill wind and solar.

Weekend listening

Electricity demand is booming, and it’s not just because of artificial intelligence. So much so that many are ready to revisit the idea of nuclear power. Microsoft signed a $16 billion deal to reopen the Three Mile Island nuclear plant to power their data centers for the next 20 years. 

But developed countries haven’t built more than a handful of new reactors in decades. When they have tried, the cost of those nuclear plants and the time to build them has been extraordinary. Will this renewed interest yield different results? 

Nuclear scientist and partner at venture capital firm DCVC Rachel Slaybaugh joined Akshat Rathi on Zero to discuss how these new dreams of growing nuclear power can become a reality. Listen now, and subscribe on AppleSpotify, or YouTube to get new episodes of Zero every Thursday.
