Resilience Investments Paid Off in Florida
During Hurricane Milton

By Lewis Nibbelin, Contributing Writer, Triple-I

Babcock Ranch – a small community in southwestern Florida dubbed “The Hometown of Tomorrow” – made headlines for sheltering thousands of evacuees and never losing power during Hurricane Milton, which devastated numerous neighboring cities and left more than three million people without power.

Hunters Point, a subdivision on Florida’s Gulf Coast, remained similarly unscathed during both Hurricanes Helene and Milton. Though the development is only two years old, it’s already been through four major hurricanes. Its homes were designed with an elevation high enough to avoid severe flooding and materials that make them as sturdy as possible in high winds. When the power goes out, each home turns to its own solar panels and battery system.

For residents of both communities, this news comes as no surprise; their flood-resistant infrastructure and solar panel power systems have helped them survive several storms and hurricanes with only minor damages, demonstrating the utility of disaster resilience planning.

Such planning is expensive to implement. Homes in either community can run for over a million dollars. But, as the combined costs of Hurricanes Helene and Milton rise to the tens of billions, it’s hard to overstate the long-term benefits. Every dollar invested in disaster resilience could save 13 in property damage, remediation, and economic impact costs, suggesting risk mitigation and recovery strategies will become even more essential as natural catastrophe severity increases.

Incentivizing investment

The National Flood Insurance Program (NFIP) Community Rating System (CRS) – a voluntary program that rewards homeowners with reduced premiums when their communities invest in floodplain management practices that exceed NFIP minimum standards – aims to encourage resilience. Class 1 is the program’s highest rating, qualifying residents for a 45 percent reduction in their premiums. Of the nearly 23,000 participating NFIP communities, only 1,500 participate in the CRS. Of those 1,500, only two – Tulsa, Okla., and Roseville, Calif. – have achieved the highest rating.

High ratings are difficult to secure and maintain. Homeowners in Lee County, which borders Babcock Ranch, nearly lost their discounts earlier this year due to improper post-Hurricane Ian monitoring and documentation within flood hazard areas.

Discounts in lower-rated jurisdictions, however, still equate to large premium reductions. Miami-Dade County, Fla., for instance, earned a Class 3 rating after extensive stormwater infrastructure upgrades, saving the community an estimated $12 million annually. Residents sustained minimized flooding from Hurricane Milton under these improvements, further justifying their cost.

Local mitigation efforts offer targeted resilience solutions and resources to alleviate community risks. The insurance industry-funded Strengthen Alabama Homes provides homeowners grants to retrofit their houses along voluntary standards for constructing buildings resistant to severe weather. Completed retrofits reduce post-disaster claims and qualify grantees for substantial insurance premium discounts, prompting flood-prone Louisiana to replicate the program.

Other nature-based planning exploits local flora as a source of natural hazard protection. Previous studies support conserving natural wetlands and mangroves to impede the rate and flow of flooding, leading many communities – including Babcock Ranch, which is 90 percent wetlands – to invest in green infrastructure. Reforestation and wetland restoration projects undertaken by the Milwaukee Metropolitan Sewerage District (MMSD) also promise to store or capture millions of gallons of storm and flood water, enabling risk management alongside improved quality of life for citizens.

Most resilience projects are impossible to fund or operate without stakeholder partnerships and advanced data and analytics. Insurers, who have long assessed and measured catastrophe risk utilizing cutting-edge data tools, are uniquely positioned to confront these evolving risks and present a framework for successful preemptive mitigation.

Hail: The “Death by 1,000 Paper Cuts” Peril

By Lewis Nibbelin, Contributing Writer, Triple-I

Earlier this year, baseball-sized hailstones in Denver totaled vehicles and pummeled homes and businesses during the second-costliest hailstorm in Colorado history, equating to billions in damages. Melon-sized stones hit Texas the same month, downing power lines and requiring snow plows to reopen roads.

Hail – a sub-peril of severe convective storms (SCS), which also include thunderstorms with lightning, tornadoes, and straight-line winds – is among the most destructive natural catastrophes in the United States, behind as much as 80 percent of SCS claims in any one year. Yet hailstorms remain ill-monitored and highly unpredictable due to a lack of public and industry attention.

“These are death-by-1000-paper-cut perils,” explained Triple-I’s Non-Resident Scholar Dr. Victor Gensini, meteorology professor at Northern Illinois University and leading expert in convective storm research, in an interview for the All Eyes on Research podcast. “In general, we’re seeing hail on 200 out of 365 days of the year.”

While individual SCS events generating losses on the multi-billion-dollar scale of Hurricane Andrew or Katrina don’t happen, over the course of a given year the losses add up quickly.

SCS, which are rising in frequency and severity – accounted for 70 percent of insured losses globally the first half of 2024, at a billion-dollar sum 87 percent higher than the previous decade average. And in 2023, U.S. insured SCS-caused losses exceeded $50 billion for the first time on record for a single year, propelled by thousands of major hailstorms impacting more than 23 million homes.

Gensini – who was motivated to study atmospheric science after a tornado impacted his high school – shifted his focus away from tornadoes “because hail is way more common across the United States every year, and it has a much larger socioeconomic impact – whether you’re talking about agricultural losses…or just rooftop damage to your asphalt shingles,” he told host and Triple-I Economic Research Analyst Marina Madsen.

“When you take a step back and look at the thunderstorm perils producing the greatest number of insured losses, it’s hail.”

Urbanization and inflation drive these losses, as more people populate disaster-prone areas and the value of their assets and the costs to repair them have increased. The expanding presence of solar farms, spread throughout flat, originally uninhabited plains, are especially susceptible to SCS damage, with one 2019 hailstorm causing $70 million in damages to a solar energy project in Texas.

Another explanation for greater hail-related losses is our warming climate. A Climate and Atmospheric Science study led by Gensini projects that, while higher temperatures will melt more hailstorms overall, increasingly large hailstones will become more common. Stronger updrafts fueled by higher temperatures can suspend stones in the air for longer, spurring further growth.

Such trends do not bode well for insurance premium rates, but upcoming research efforts promise actionable insight into hailstorm detection and prediction. The In-situ Collaborative Experiment for the Collection of Hail in the Plains – or ICECHIP – will send Gensini and several other researchers into the Great Plains to chase and collect granular data from hailstorms next year. Backed by the National Science Foundation with more than $11 million in funding, the field study aims to reduce hail risk through improved hailstorm forecasting, enabling residents to better protect themselves and their belongings before a hailstorm touches down.

A newer initiative – the Center for Interdisciplinary Research on Convective Storms, or CIRCS – is a prospective academic industry consortium to develop multidisciplinary research on SCS risk, fostering resilience and recovery strategies informed by diverse stakeholder partnerships.

“As you can imagine, the greatest interest right now in our research is in the insurance and reinsurance verticals,” Gensini said. “Hopefully, as we continue to build relationships…the [CIRCS] center will serve as a hub for information and knowledge creation for industry members. It’s a really unique consortium and a lot of potential lines of business could benefit from it.”
