Last week with a major hurricane bearing down on Houston, President Donald Trump tweeted, “As #HurricaneHarvey intensifies—remember to #PlanAhead.” Sound advice. But just one week prior, Trump signed an executive order overturning an in-progress Obama-era directive intended to help the country prepare for flooding as it becomes more frequent in some places largely due to climate change.

The previous administration came up with the Federal Flood Risk Management Standard after Hurricane Sandy devastated parts of New York and New Jersey and caused more than $62 billion in damage. The rule required new housing and infrastructure projects receiving public money to be elevated 2 to 3 feet above their local 100-year flood height—the same standard applied by the Rebuild by Design competition in New York and New Jersey after Sandy.

Now that the rule has been revoked, “taxpayer dollars will likely be wasted through investments in projects that could be washed away in the next storm,” said Rachel Cleetus, climate policy manager at the Union of Concerned Scientists, in a statement.

For Mark Ginsberg, FAIA, a partner at New York–based Curtis + Ginsberg Architects who co-chaired a post-Sandy housing task force for the Department of Housing and Urban Development (HUD), this ruling demonstrates a clear regression in flood policy. “It took FEMA years to change the rule to something more intelligent and forward thinking,” Ginsberg says. “And now it is being taken back.”

Laurie Schoeman, who worked on post-Sandy recovery efforts for the nonprofit housing developer Enterprise Community Partners and now oversees green building for the organization, says she was baffled by the decision. “When you roll that kind of policy back and don’t come up with anything to replace it, what you’re saying is, ‘Let’s just keep putting Band-Aids on the problem, let’s not think about the challenge of climate change,’ ” Schoeman says.

But Albert Slap, whose company Coastal Risk Consulting helps homeowners and developers defend their properties against rising seas, says the president’s decision to roll back the Federal Flood Risk Management Standard won’t have a huge impact on the built environment. “Nobody thinks that what Trump did makes any sense at all,” Slap says, but he contends the market already demands that designers take flood risk into account. “Anyone who doesn’t want to get sued for malpractice is going to use not some 2 or 3 foot rule, they’re going to study the site,” he says. “Just because Trump says, ‘Don’t worry about sea-level rise,’ do you think architects and engineers in America are going to say, ‘It’s all good?’ ”

But Schoeman worries that architects working with constrained budgets won’t go beyond what’s required by code, leaving more buildings vulnerable to future flooding. Potential budget cuts at the federal agencies in charge of grants for new housing and infrastructure might make that problem worse.

Marion McFadden, who helped develop flood-risk standard as former deputy assistant secretary for grant programs at HUD, says the rule’s repeal puts billions of dollars of property at risk.

“Whether you think sea-level rise, river flooding, and the increased severity of hurricanes are the result of manmade or natural changes, we have a common financial interest in preventing the federal government from footing the bill for poor planning,” says McFadden, who is now vice president of public policy at Enterprise Community Partners.

The Trump administration says undoing the flood-risk standard is part of a broader effort to make it easier to build new infrastructure by cutting red tape. Alice Hill, a former special assistant to President Barack Obama who helped write the rule, pushed back against that idea in Newsweek. “For those who say we cannot afford to build to the Federal Flood Risk Management Standard, I say, as a federal taxpayer, that we cannot afford not to,” Hill wrote. “If we make a modest investment in building higher in advance of floods, we can reduce the amount of future federal disaster bailouts. The Standard not only saves money, it saves lives.”

The AIA, too, issued a statement condemning the decision, writing, “The AIA opposes rollbacks of policies that endanger the built environment, and more importantly, endanger the humans that live in it.”

No matter the politics, flood waters are still rising in Texas, days after Hurricane Harvey made landfall. The National Weather Service has already called the storm “unprecedented” and “beyond anything experienced.”

Emergency responders and civilian volunteers completed more than 1,200 high-water rescues over the weekend—work that will continue as the storm pours a record-breaking 50 inches of rain on parts of Texas over the next few days. But after the rescue and recovery efforts, Houston will have to plan for the next storm. In the absence of direction from the federal government, it may be up to local architects, planners, and developers to make sure their cities are ready.
