Florida leads the nation in strict building codes, and the decades of hard work have paid off in the increasing number of homes and buildings that survive each time a hurricane slashes the state.
But a new report from Swiss Re, a major global re-insurance company, suggests that all those hard-won gains have been undermined by the explosion of growth along the coast. And that has likely helped fuel the skyrocketing price of wind-storm insurance across the state.
One year ago, Hurricane Ian struck Southwest Florida as a powerful Category 4 that wiped whole blocks off the map along the coast and damaged homes and roofs miles inland. It鈥檚 the most expensive storm in the state鈥檚 history.
If that same storm had struck in the 1970s, the Swiss Re report said, it would have caused half or even a third as much damage as it did.
And while building codes have improved dramatically since 2002, when the updated standards went statewide, the biggest driver behind Ian鈥檚 outsize impact was just how many people now live in the strike zone.
鈥淥ur models show a clear imbalance: Reducing vulnerability by strengthening building codes, a key element of adaptation, has been insufficient since the 1970s to compensate for expected losses from accompanying population-driven property value growth,鈥 the report, released Monday, read.
鈥榃e do know how to build better鈥
Some building code experts disagreed with pointing the finger at sprawling growth along the coast for the soaring damage losses and insurance premiums. They argue it鈥檚 the state鈥檚 aging housing stock that is most vulnerable and newer homes and upgraded old ones have endured high winds better and helped reduce risks.
鈥淚 don鈥檛 think they鈥檙e equal forces,鈥 said Leslie Chapman-Henderson, president of FLASH, or the Federal Alliance for Safe Homes. 鈥淲e鈥檝e seen the survival of even the most affordable homes in the path of these storms.鈥
Dorothy Mazzarella, vice president for government relations for the International Code Council, said her key takeaway from the report is the recognition that better building codes work.
She said people will always want to live along Florida鈥檚 coastline, no matter how vulnerable it is 鈥 or how expensive it gets to live there 鈥 so the answer is to better prepare for future storms.
鈥淲e have to do more on the front end, which is the mitigation side,鈥 Mazzarella said. 鈥淲e can鈥檛 prevent them, but we know we can prepare for them.鈥
However, Chapman-Henderson added, relying on new construction to strengthen the state鈥檚 risky spots only addresses a small part of the problem.
Older homes, built before effective hurricane-resistant building codes kicked in, make up the majority of Florida鈥檚 housing stock.
In the areas touched by Ian鈥檚 winds alone, about 69% of the properties were built before 2000, according to the Wall Street Journal鈥檚 review of census data and National Hurricane Center records. And fixing them is more complicated than simply building a new home from scratch.
In Lee County, there鈥檚 been a backlash against bringing storm-damaged homes all the way up to the newest version of the code, a pricey endeavor that may involve elevating it several feet.
鈥淯nfortunately, this is the clash of what鈥檚 affordable and what鈥檚 achievable and what鈥檚 ideal,鈥 Chapman-Henderson said. 鈥淲e do know how to build in the face of these disasters that cost millions of dollars. We have to maintain the will to do so on a consistent basis.鈥
Stronger homes, cheaper insurance
So would fortifying every single property in risky areas solve this problem? Not exactly, said Erdem Karaca, head of catastrophe perils in the Americas for Swiss Re and co-author of the report.
While more and more homes and buildings are better prepared for storms, packing in a much higher volume of people just increases the number of chances something could go wrong.
Karaca points to the many pool screens destroyed on homes miles inland from Hurricane Ian. Yes, he said, the homes may have been in good shape, but all those little damages still up, and they鈥檙e why wind is the number one threat from an insurance perspective, while storm surge remains the biggest threat to life.
鈥淭he more people live there, the more pools we have, it tallies up,鈥 he said.
Insurance premiums are based, in part, on the risk in an entire area. So if that risk is constantly rising, the premiums will too.
But if enough homes and buildings are safe from storms, that could potentially drive down the risk, and therefore insurance costs, said Matt Junge, the head of property underwriting in the U.S. for Swiss Re.
鈥淔or insurance companies to provide insurance, they have to have confidence they鈥檙e going to predict what鈥檚 going to happen,鈥 he said.
Junge said he was 鈥渙ptimistic鈥 that Florida鈥檚 recent efforts to curtail another issue in the market, the glut of fraudulent lawsuits, was going to help bring premiums down eventually.
And he said that the more Florida can strengthen its housing stock, the more that trend can continue. 鈥淚t鈥檒l take some time,鈥 he cautioned.
鈥楯ust because you can doesn鈥檛 mean you should鈥
The report also took into account another factor affecting coastal storms in Florida 鈥 climate change. Karaca and his co-author found that the increasingly warmer ocean, which is linked to stronger and wetter hurricanes, could have also played a role in making Hurricane Ian a worse storm than a similar one in 1970, when waters were cooler.
And that impact, plus the massive population gains in Southwest Florida, significantly outweighs the last twenty years of stricter building practices.
That puts Florida鈥檚 coastline in the cross-hairs of even stronger storms in the future, with a whole lot more people there to experience them.
That gives Vivian Young, communications director for 1,000 Friends of Florida, a smart growth advocacy group, pause. She praised the state鈥檚 commitment to building better, but wondered how far that can really take us.
Storms don鈥檛 just impact homes, they rip up roads, crack water pipes and flood government buildings. Recovering from a storm comes at a high cost to taxpayers, both locally and federally.
And in Florida, plenty of that risk is insured through public-run, deeply subsidized programs like Citizens, the state-run insurer of last resort.
鈥淲e鈥檙e kind of punting the problem down the road a bit,鈥 she said. 鈥淭axpayers are paying through Citizens or the National Flood Insurance Program for rebuilding in these vulnerable areas, but is that really the best option?鈥
Climate change is increasing the chances of stronger and more deadly storms, and sea level rise could permanently inundate swaths of Florida鈥檚 coastline, making it inconvenient and expensive to live there.
Young said the technology may be out there to help homes withstand even the strongest winds from a powerful hurricane, but the cost of insuring a home that weathers an extreme storm, or even moderate flooding, regularly could become too much for homeowners, or even banks.
鈥淚 think the state is reaching a tipping point and there鈥檚 going to have to be a really serious conversation about where it鈥檚 appropriate to develop, where we should be redeveloping and whether we should live in certain areas at all,鈥 she said.
It鈥檚 like the old adage with new cutting-edge technology, she said. 鈥淛ust because you can doesn鈥檛 mean you should.鈥
