The high costs of climate risk
Anyone who has been through a flood or hurricane knows the scene: waterlogged furniture piled on curbs, gutted homes with mold creeping up the walls, families displaced for months. But the recovery isn’t the same for everyone.
While federal flood insurance subsidizes risky coastal and waterfront development for wealthier homeowners by lowering the cost of living in these areas, many low-income households in flood-prone areas remain stuck with risky properties and little help.
As a disaster recovery researcher, I’ve witnessed how perverse incentives create different cycles of vulnerability across income levels. The problem with federal disaster insurance today isn’t just about subsidizing wealthier coastal homeowners – it’s equally about leaving low-income households systematically underinsured without resources to either protect themselves or leave.
Federal flood insurance’s moral hazards
The National Flood Insurance Program was established by Congress in 1968 to provide affordable flood insurance to the public while encouraging floodplain management.
Communities that participate in the program are required to adopt regulations to reduce flood risk in their areas for their residents to qualify. The insurance policies, around 4.7 million today, are purchased either through the program or insurance companies but administered and underwritten by the Federal Emergency Management Agency, the nation’s disaster response agency. When the policy cost is lower than the risk, the property is being subsidized by the federal program.
The National Flood Insurance Program did succeed in providing accessible insurance for many people, but it also produced a “moral hazard,” where people take on risk without bearing its full consequences. What’s less well understood is that this operates differently by income level.
FEMA is currently working to adjust flood insurance prices to more closely match each property’s actual risk. The program’s Risk Rating 2.0 changes, which began in 2021, aimed to transition policies to full-risk pricing for everyone. The annual premium increases are capped by law at 18% for primary residences, so full-risk pricing won’t be fully reached until around 2037, according to federal estimates.
But there’s another, less visible problem: Federal flood insurance already wasn’t affordable for many people.
In low-income neighborhoods, more than 90% of households are estimated to be underinsured, and their uninsured losses when they experience flooding often exceeds 20% of their annual income.
Many families are unable to afford federal flood insurance premiums – only 37% of all policyholders pay less than $1,000 per year, according to FEMA. Instead, homeowners may skip insurance, gambling that disasters won’t strike. When floods do occur, these households can face catastrophic uninsured losses.
Homeowners and renters may also choose federal flood insurance plans with lower premiums but that provide less coverage in a disaster, and even those plan costs can be high.
Because the federal flood insurance program doesn’t specifically help those who cannot afford premiums, this creates a structural trap: Wealthier homeowners receive government-subsidized insurance support for risky properties, while many lower-income households fall outside the system entirely.
EDITOR'S NOTE: Last year, Cathy and I received two homeowner insurance cancellations because of climate risk. A final carrier agreed to cover us on the condition we also buy federal flood insurance even though we are up on the tip of the moraine north of Route 1. That added an additional $1200 to the high premium charged by the new carrier. - Will Collette
