Driving through the mess left behind by the twin hurricanes that slammed Florida, it doesn’t take long to pass a construction site for another batch of new homes.
Among them is La Linda Estates, which is being built in a high-risk flood zone on a barrier island near where Milton made landfall.
Florida built 77,000 new properties in high-risk flood areas since 2019, the most in the nation, according to an analysis by climate-modeling firm First Street Foundation for The Wall Street Journal. The building binge is putting the real-estate industry, and the banks that finance it, on a collision course with insurers.
The new construction is one reason insurance bills for Milton and Helene are expected to be between $40 billion and $75 billion, according to ratings firm Morningstar DBRS. Big payouts from natural disasters are driving insurers to raise raises and pull back on coverage.
Nationally, 290,000 new properties were built in high-risk flood areas from 2019 through 2023, almost one in five of the 1.6 million built in total in that period, the First Street analysis found. Other states with heavy new construction in areas at high risk of flooding include Texas, with 63,000 properties since 2019, California with 21,000 properties, and North Carolina with 11,000, the First Street analysis found.
“We build in some of the most silly places, knowing what could happen,” said Andrew Siffert, senior meteorologist at insurance broker BMS Group. New development was one of the main reasons insured losses from catastrophes are increasing.”
“The lenders need to play a role,” said Robert Gordon, a senior vice president at industry body the American Property Casualty Insurance Association and whose family had to evacuate from Tampa ahead of Milton. “The lenders can be on the hook for decades while insurers can raise rates every six to 12 months. The lenders…are really in the best position to make sure there’s the right consideration of the long-term risk. A lot of times that’s not happening right now.”
Even as climate change drives up the frequency and severity of natural disasters, developers keep building in harm’s way. La Linda Estates is made up of 13 homes on Siesta Key near Sarasota, located steps from the Gulf of Mexico. They sell for just under $3 million. Listings say they are at high risk of flooding and wind damage, as well as high heat. The area was still cleaning up from Helene when Milton hit.
Dustin Anderson, a Realtor at Serhant selling the homes, said they “did not have any major damage” after Helene or Milton. The developer Pampa Sunbelt said the homes have a concrete structure and conform to Florida’s design code.
Americans moved to risky areas as they became more vulnerable because of climate change. In the decade through 2020, the U.S. population overall grew 7.4% but rose 10.2% in the South and 9.2% in the West, including areas vulnerable to storms and wildfires, according to ratings firm AM Best.
Home insurers racked up more than $32 billion in underwriting losses in the four years through last year, according to ratings firm S&P Global. The result is premiums “have nowhere to go but up,” Morningstar said in a research note on Monday.
Lenders and developers counter that they take climate risks into account for new buildings. A study by reinsurer Swiss Re found the reduction in hurricane damage because of Florida’s strict building standards was significant. But it was far outweighed by the increased losses caused by an influx of millions of sunseekers.
Developers are making matters worse by skirting official flood zones while still building in high-risk flood areas, the First Street analysis suggests. Typically, high-risk flood zones are designated by the Federal Emergency Management Agency as official Special Flood Hazard Areas, which exclude factors such as heavy rainfall and can be outdated.
First Street says high-risk zones are bigger than the official maps suggest. Homes built in official flood zones need to get flood insurance if supported by a government-backed mortgage and conform to tougher building codes, making them more expensive for buyers. Just outside of the official zones, but inside what First Street considers high risk, those requirements don’t exist. That is where developers are building.
Of the 77,000 recently built properties in Florida that First Street identified as at high risk of flooding, 41,000—or more than half—fell outside the official flood zones. Nationally, 211,000 properties were built outside official flood zones but within First Street high-risk areas in the five years through last year, the analysis found.
“Millions of people are at heightened risk of flooding in hurricanes, without the protection against that risk they would be afforded if flood zones were more accurate,” said Jeremy Porter, First Street’s head of climate-implications research.
“FEMA uses the latest science and data for its maps,” said a spokeswoman for FEMA, which is responsible for the flood zones. “The process is careful to neither understate nor overstate the current flood risk.”
“States such as Florida should consider changing the building codes for areas that aren’t in official high-risk flood zones, and just go up a foot or so,” said Trevor Burgess, chief executive of insurer Neptune Flood. “The sea level in my Florida hometown—and Milton target—St. Petersburg is nearly a foot higher than when I was born,” the 52-year-old said.
He was speaking from Washington, D.C., where he had evacuated. He didn’t yet know whether his house was damaged.
A Journal analysis of high levels of new construction in flood-prone areas of South Florida identified clusters of new housing in the Miami area, including areas such as Richmond West, Goulds, Princeton, Leisure City, Homestead and Florida City.
Builder Lennar invites home buyers to “live life in ultimate style and comfort” at a development of hundreds of houses plus a golf course in the Miami suburb of Homestead. The site of the development, called Altamira, is in an area classified by First Street as a high flood risk.
Homestead was flattened in 1992 by Hurricane Andrew, which was the costliest storm to hit Florida for 25 years. One result was Florida’s tough building code, another was that insurers began their retreat from the state.
