A Q&A with Villanova’s Stephen M. Strader on the legacy of Hurricane Andrew, unsustainable development, and why building codes alone aren’t enough.
In around 12 hours, Hurricane Milton is set to make landfall within miles of Tampa Bay, a region that is home to more than 5 million people. Once a sleepy retirement community, the area has seen a major development boom in recent years fueled by Millennials and Gen Zers seeking the perks of coastal living; it was the 11th fastest-growing city of its size in the U.S. as of this spring and has been expected to continue to grow at nearly twice the rate of the rest of the country over the next five years. A third of those residents, including many of the newcomers, live in low-lying neighborhoods now under urgent evacuation notices due to the threat of “unsurvivable” storm surge, which could rise up to 15 feet.
The development boom that has made Tampa Bay so desirable is also why it’s particularly vulnerable. In an analysis of Hurricane Ian — the most expensive storm in Florida’s history, which struck just south of Milton’s projected track in 2022 — the re-insurance company Swiss Re found that if the storm had struck in the 1970s, it would have caused a third to a half as much damage. Simply put: You can’t adapt your way out of a hurricane problem.
If there is anyone to talk to about the vulnerabilities unique to Tampa Bay, it’s Stephen M. Strader, an associate professor and hazard geographer at Villanova University. Our conversation has been edited and condensed for clarity.
You shared an image on Twitter of the explosive growth in the Tampa Bay area between 1940 and 2024. Why does this make the region vulnerable to a storm like Milton? Is it just about there being more people there?
When we think about disasters, we think of the intersection of three components: a violent event, like what we have with Milton; vulnerability, or what types of people could be in the path, which could be related to racial divides, age, and gender norms; and what a lot of my work focuses on, exposure.
Exposure is just the number of people or things that we care about — businesses, schools, and things like that — that are subject to losses if an event occurs. Florida is a great example of rapid urbanization since the 1900s, and it’s rapid development in a very hazard-prone region.
It can be easy for outsiders to sit back and wonder why anyone would buy a house on the water or on a barrier island near Tampa.
There are a lot of factors that come into play when you think about where we develop and why we develop certain locations. One of the biggest pressures that we see is that it’s desirable land: In the short term, people want to live near the water. It’s beautiful! People don’t think necessarily about the risk that comes with it because they’re too focused on their dream, which is to live near the ocean.
The other side of that is, from an economic standpoint, people see it as an opportunity to have businesses and to build condos. Developers see the land and think, “How much could I buy this for and sell it for with homes on it?” This really started back with Carl Fisher, who was famous for building the Indianapolis Motor Speedway. He was a thrill-seeker, but also a businessman and developer, and he loved to go to South Florida — which is now Miami Beach, and then was swamps and mangroves and not developed at all. And he thought, Hmm, this would be a great place for people to visit for vacations and experiences. He slowly started filling in the wetlands with sand. And that’s the history of Florida's development: It continued because this was very valuable land.
There is a lot of socioeconomic pressure to develop in these areas, but we’re also starting to see it change. Those pressures are lessening because you have insurance industries now and events like this year after year.
There is another issue in Southwest Florida, which is that many of the homes were constructed before building codes were updated, right?
I tend to do a lot more work on the manufactured housing side. Before 1974, all manufactured homes were called mobile homes, and there wasn’t really a standard. Then, in 1974, the United States Department of Housing and Urban Development came in and said, “We need to increase the standards,” and they did.
Fast-forward to 1992 and Hurricane Andrew, and they realized these codes were not strong enough. Many people lived in manufactured homes that were destroyed by Andrew, which was a very windy hurricane. We think hurricanes are wind threats because of Andrew, but hurricanes are water threats, and most deaths occur because of that water. Andrew was the opposite.
Between 1992 and 1994, they updated building codes for manufactured housing, and actually, along the coastline, Florida has some of the strongest codes for manufactured homes in the country. A lot of the areas that will be affected by Milton will have those strong standards. But many homes were also grandfathered in if they were built before that time.
That’s just one type of housing. My guess is that when you have a lot of rapid development since the 1990s — well, I have some questions about structural integrity since building codes can be strong but they might not be followed. And we sometimes don’t know until afterwards. A lot of what is being built are condos or McMansions — it’s basically, How fast can you build them, how cheap can you build them, and how high can you sell them? And they look great until their performance is put into question.
Insurance companies are starting to see this and ask, “How do we retrofit structures?” Structure-wise, though, I think Tampa is in a decent spot. The problem is, the water is so powerful that it’s not going to matter.
What kinds of conversations do you think Floridians should be having about development or potential redevelopment after Milton?
I’m a huge proponent of resisting the urge to build right back — the reason being that’s how you get repetitive losses. The hard part is, with a lot of insurance, if you have it, you only get provisions to build back the way you were. You don’t have the ability to improve. So what I end up telling people is, sometimes these disasters provide an opportunity to assess what we need to do from a planning standpoint. This is unsustainable development, and not just because of hurricanes, but because of rising sea levels and the stress on the environment. And unfortunately, a lot of these developments were built on top of wetlands and marshes and mangroves that used to protect the island areas as natural barriers.
The hard part is that people’s emotions are very strong after disasters, and they immediately want to return to how things were. That’s why you see people picking up the pieces the day after a storm, sometimes even when they’re injured. So we have to resist the urge as a group, and say, maybe this isn’t the time to think about rebuilding here.
Many wetland restoration projects in Florida are doing that very thing: reclaiming the environments that protected people inland. But on the other side you have developers and builders and local economies that rely on people coming to these areas, and that pressures people to come right back. Then you end up with a situation of repetitive losses and that’s why FEMA has been losing money over the years — it’s not so much that we’re putting money toward disasters but that we’re not getting value out of it, because it’s so much more likely for there to be impacts because of that exposure growth. Look at what happened after Helene and what’s going to happen with Milton: We’re splitting resources between the two. But we’re doing the best with the tools we have when there’s pressure on both sides, and considerations both economic and safety.
Is there anything else people should know about the geography of Tampa or the development risk there?
This storm is going to be different than other storms, and that’s because of the direction and intensity of it. The one thing we have to remember is that all that development — and everybody, for the most part, who isn’t 100 years old — has not experienced a hurricane of this magnitude in their life. That means everyone has the cognitive bias to say, “I’ve been through hurricanes before and was fine.” That is probably not going to be the case with this event; no one has been through this before.
What’s worrisome to me is that the trajectory of the hurricane is changing. A subtle shift north or south by 20 miles could mean a big difference for the Tampa region — if you have the right side of the hurricane push water into the Bay, it’s no different than 10 people jumping into a hot tub. The water level goes up and forces all that water into a smaller region, which is going to lead to more storm surge in Tampa Bay, Clearwater, and the St. Pete area. I don’t want to call it a “perfect storm,” but if you push all that water in there, you’re going to flood people in a way that hurricanes they’ve been through before never got close to. And I worry, if it goes south, about Fort Myers and the areas that were hit hard by Hurricane Ian. So it’s multilayered.
The good news that I’ll bring up is that we’re reeling from Helene, which means people have it in their brains about how bad this can be, which is probably causing more people to evacuate than normal. We have a problem with disaster amnesia in places where a hurricane hasn’t happened in a long time so “it’s not going to happen again.” And we forget. I remember Hurricane Katrina and what it did to New Orleans. It still has effects, but the students I’m teaching now weren’t even alive when it hit. These memories are short, and many people in Florida today weren’t there 30 years ago or 20 years ago. The only good thing to come out of Helene is that people are now aware of what can happen.

Current conditions: The remnants of Tropical Storm Chantal will bring heavy rain and potential flash floods to the Carolinas, southeastern Virginia, and southern Delaware through Monday night • Two people are dead and 300 injured after Typhoon Danas hit Taiwan • Life-threatening rainfall is expected to last through Monday in Central Texas.

The flash floods in Central Texas are expected to become one of the deadliest such events in the past 100 years, with authorities updating the death toll to 82 people on Sunday night. Another 41 people are still missing after the storms, which began Thursday night and raised the Guadalupe River some 26 feet in less than an hour, providing little chance for holiday weekend campers and RVers to escape.
Although it’s far too soon to definitively attribute the disaster to climate change, a warmer atmosphere is capable of holding more moisture and producing heavy bursts of life-threatening rainfall. Disasters like the one in Texas are one of the “hardest things to predict that’s becoming worse faster than almost anything else in a warming climate, and it’s at a moment where we’re defunding the ability of meteorologists and emergency managers to coordinate,” Daniel Swain of the University of California Agriculture and Natural Resources told the Los Angeles Times. Meteorologists who spoke to Wired argued that the National Weather Service “accurately predicted the risk of flooding in Texas and could not have foreseen the extreme severity of the storm” ahead of the event, while The New York Times noted that staffing shortages at the agency following President Trump’s layoffs potentially resulted in “the loss of experienced people who would typically have helped communicate with local authorities in the hours after flash flood warnings were issued overnight.”
President Trump announced this weekend that his administration plans to send up to 15 letters on Monday to important trade partners detailing their tariff rates. Though Trump didn’t specify which countries would receive such letters or what the rates could be, he said the tariffs would go into effect on August 1 — an extension from the administration’s 90-day pause through July 9 — and range “from maybe 60% or 70% tariffs to 10% and 20% tariffs.” Treasury Secretary Scott Bessent added on CNN on Sunday that the administration would subsequently send an additional round of letters to 100 less significant trade partners, warning them that “if you don’t move things along” with trade negotiations, “then on August 1, you will boomerang back to your April 2 tariff level.” Trump’s proposed tariffs have already rattled industries as diverse as steel and aluminum, oil, plastics, agriculture, and bicycles, as we’ve covered extensively here at Heatmap. Trump’s weekend announcement also sent jitters through global markets on Monday morning.
President Trump’s gutting of the Inflation Reduction Act with the signing of the budget reconciliation bill last week will add an extra 7 billion tons of emissions to the atmosphere by 2030, a new analysis by Climate Brief has found. The rollback on renewable energy credits and policy means that “U.S. emissions are now set to drop to just 3% below current levels by 2030 — effectively flatlining — rather than falling 40% as required to hit the now-defunct [Paris Agreement] target,” Carbon Brief notes. As a result, the U.S. will be about 2 billion tons short of its emissions goal by 2030, adding an emissions equivalent of “roughly the annual output of Indonesia, the world’s sixth-largest emitter.”
To reach its conclusions, Carbon Brief utilized modeling by Princeton University’s REPEAT Project, which examined how the current obstacles facing U.S. wind and solar energy will impact U.S. emissions targets, as well as the likely slowdown in electric vehicle sales and energy efficiency upgrades due to the removal of subsidies. “Under this new set of U.S. policies, emissions are only expected to be 20% lower than 2005 levels by 2030,” Carbon Brief writes.
Engineering giant SKF announced late last week that it had set a new world record for tidal turbine reliability, with its systems in northern Scotland having operated continuously for over six years at 1.5 megawatts “without the need for unplanned or disruptive maintenance.” The news represents a significant milestone for the technology since “harsh conditions, high maintenance, and technical challenges” have traditionally made tidal systems difficult to implement in the real world, Interesting Engineering notes. The pilot program, MayGen, is operated by SAE Renewables and aims, as its next step, to begin deploying 3-megawatt powertrains for 30 turbines across Scotland, France, and Japan starting next year.
Satellites monitoring the Southern Ocean have detected for the first time a collapse and reversal of a major current in the Atlantic Meridional Overturning Circulation. “This is an unprecedented observation and a potential game-changer,” said physicist Marilena Oltmanns, the lead author of a paper on the finding, adding that the changes could “alter the Southern Ocean’s capacity to sequester heat and carbon.”
A breakthrough in satellite ocean observation technology enabled scientists to recognize that, since 2016, the Southern Ocean has become saltier, even as Antarctic sea ice has melted at a rate comparable to the loss of Greenland’s ice. The two factors have altered the Southern Ocean’s properties like “we’ve never seen before,” Antonio Turiel, a co-author of the study, explained. “While the world is debating the potential collapse of the AMOC in the North Atlantic, we’re seeing that the Southern Ocean is drastically changing, as sea ice coverage declines and the upper ocean is becoming saltier,” he went on. “This could have unprecedented global climate impacts.” Read more about the oceanic feedback loop and its potential global consequences at Science Daily, here.
The French public research university Sciences Po will open the Paris Climate School in September 2026, making it the first school in Europe to offer a “degree in humanities and social sciences dedicated to ecological transition.” The first cohort will comprise 100 master’s students in an English-language program. “Faced with the ecological emergency, it is essential to train a new generation of leaders who can think and act differently,” said Laurence Tubiana, the dean of the Paris Climate School.
A fifth of U.S. counties now restrict renewables development, according to exclusive data gathered by Heatmap Pro.
A solar farm 40 minutes south of Columbus, Ohio.
A grid-scale battery near the coast of Nassau County, Long Island.
A sprawling wind farm — capable of generating enough electricity to power 100,000 homes — at the northern edge of Nebraska.
These projects — and hundreds of others — will never get built in the United States. They were blocked and ultimately killed by a regulatory sea-change that has reshaped how local governments consider and approve energy projects. One by one, counties and municipalities across the country are passing laws that heavily curtail the construction of new renewable power plants.
These laws are slowing the energy transition and raising costs for utility ratepayers. And the problem is getting worse.
The development of new wind and solar power plants is now heavily restricted or outright banned in about one in five counties across the country, according to a new and extensive survey of public records and local ordinances conducted by Heatmap News.
“That’s a lot,” Nicholas Bagley, a professor at the University of Michigan Law School, told us. Bagley said the “rash of new land use restrictions” owes partly to the increasing politicization of renewable energy.
Across the country, separate rules restrict renewables construction in 605 counties. In some cases, the rules greatly constrain where renewables can be built, such as by requiring that wind turbines must be placed miles from homes, or that solar farms may not take up more than 1% of a county’s agricultural land. In hundreds of other cases, the rules simply forbid new wind or solar construction at all.
Even in the liberal Northeast, where climate concern is high and municipalities broadly control the land use process, the number of restrictions is rising. At least 59 townships and municipalities have curtailed or outright banned new wind and solar farms across the Northeast, according to Heatmap’s survey.
Even though America has built new wind and solar projects for decades, the number of counties restricting renewable development has nearly doubled since 2022.
When the various state, county, and municipality-level ordinances are combined, roughly 17% of the total land mass of the continental United States has been marked as off limits to renewables construction.
These figures have not been previously reported. Over the past 12 months, our energy intelligence platform Heatmap Pro has conducted what it believes to be the most comprehensive survey of county and municipality-level renewables restrictions in the United States. In part, that research included surveys of existing databases of local news and county laws, including those prepared by the Sabin Center for Climate Change Law at Columbia University.
But our research team has also called thousands of counties, many of whose laws were not in existing public databases, and we have updated our data in real time as counties passed ordinances and opposed projects progress (or not) through the zoning process. This data is normally available to companies and individuals who subscribe to Heatmap Pro. In this story, we are making a high-level summary of this data available to the public for the first time.
Restrictions have proliferated in all regions of the country.
Forty counties in Virginia alone now have an anti-renewable law on the books, effectively halting solar development in large portions of the state, even as the region experiences blistering electricity load growth.
These anti-solar laws have even begun to slow down energy development across the sunny Southwest. Counties in Nevada and Arizona have rejected new solar development in the same parts of the state that have already seen a high number of solar projects, our data show. Since President Trump took office in January, the effect of these local rules have become more acute — while solar developers could previously avoid the rules by proposing projects on federal land, a permitting slowdown at the Bureau of Land Management is now styming solar projects of all types in the region, as our colleague Jael Holzman has reported.
In the Northeast and on the West Coast, where Democrats control most state governments, towns and counties are still successfully fighting and cancelling dozens of new energy projects. Battery electricity storage systems, or BESS projects, now draw particular ire. The high-profile case of the battery fire in Moss Landing, California, in January has led to a surge of local opposition to BESS projects, our data shows. So far in 2025, residents have cited the Moss Landing case when fighting at least six different BESS projects nationwide.
That’s what happened with Jupiter Power, the battery project proposed in Nassau County, Long Island. The 275-megawatt project was first proposed in 2022 for the Town of Oyster Bay, New York. It would have replaced a petroleum terminal and improved the resilience of the local power grid.
But opposed residents began attending public meetings to agitate about perceived fire and environmental risks, and in spring 2024 successfully lobbied the town to pass a six-month moratorium on battery storage systems. The developer of the battery storage system, Jupiter Power, announced it would withdraw after the town passed two consecutive extensions to the moratorium and residents continued agitating for tighter restrictions.
That pattern — a town passes a temporary moratorium that it repeatedly extends — is how many projects now die in the United States.
The Nebraska wind project, North Fork Wind, was effectively shuttered when Knox County passed a permanent wind-energy ban. And the solar project south of Columbus, Ohio? It died when the Ohio Power Siting Board ruled that “that any benefits to the local community are outweighed by public opposition” to the project, which would have generated 70 megawatts, enough to power about 9,000 homes.
The developers of both of these projects are now waging lengthy and expensive legal appeals to save them; neither has won yet. Even in cases where the developer ultimately prevails against a local law, opposition can waste years and raise the final cost of a project by millions of dollars.
Our Heatmap Pro platform models opposition history alongside demographic, employment, voting, and exclusive polling data to quantify the risk a project will face in every county in the country, allowing developers to avoid places where they are likely to be unsuccessful and strategize for those where they have a chance.
Access to the full project- and county-level data and associated risk assessments is available via Heatmap Pro.
And more on the week’s biggest conflicts around renewable energy projects.
1. Jackson County, Kansas – A judge has rejected a Hail Mary lawsuit to kill a single solar farm over it benefiting from the Inflation Reduction Act, siding with arguments from a somewhat unexpected source — the Trump administration’s Justice Department — which argued that projects qualifying for tax credits do not require federal environmental reviews.
2. Portage County, Wisconsin – The largest solar project in the Badger State is now one step closer to construction after settling with environmentalists concerned about impacts to the Greater Prairie Chicken, an imperiled bird species beloved in wildlife conservation circles.
3. Imperial County, California – The board of directors for the agriculture-saturated Imperial Irrigation District in southern California has approved a resolution opposing solar projects on farmland.
4. New England – Offshore wind opponents are starting to win big in state negotiations with developers, as officials once committed to the energy sources delay final decisions on maintaining contracts.
5. Barren County, Kentucky – Remember the National Park fighting the solar farm? We may see a resolution to that conflict later this month.
6. Washington County, Arkansas – It seems that RES’ efforts to build a wind farm here are leading the county to face calls for a blanket moratorium.
7. Westchester County, New York – Yet another resort town in New York may be saying “no” to battery storage over fire risks.
