SOUTH SIOUX CITY, Neb. — Rick Satterwhite’s house backs up to the Missouri River, but flood insurance hadn’t really seemed necessary — until this week, when he had to pump water out of his basement after a round of destructive storms.

It’s not the first time he has had to dry out his basement from floodwater, but bad storms are getting more frequent, he said. Satterwhite watched with dread Monday as the river came within 2 feet of his back door in Dakota City, Nebraska, after torrential rain produced record-setting Midwestern floods, destroying hundreds of properties.

“I talked to our agent today,” he said. “We’re going to get flood insurance now.”

Satterwhite is hardly alone. As the Midwest begins to recover, many won’t have flood insurance, which must be purchased separately from homeowners insurance. Federal data shows that across the flooded states of Nebraska, South Dakota, Iowa and Minnesota, the government has only issued about 26,500 flood insurance policies.

Lack of insurance can burden homeowners with out-of-pocket repair costs and place more need on nonprofits and the government, said Emily Rogan, senior program officer at United Policyholders, an insurance consumers group.

In Iowa, for example, consulting firm Milliman estimates that in 22 of the counties covered by the governor’s disaster proclamations, less than 1% of single-family homes have flood insurance from the government, which issues the vast majority of policies.

Many think flooding won’t happen to them and is hardly worth the cost of another bill, said Tom O’Meara, CEO of Independent Insurance Agents of Iowa. Iowa property insurance rates have skyrocketed in recent years after a series of expensive weather disasters, he said. Avoidance of flood insurance comes as climate change increases flood risk, creating conditions that produce wetter rainstorms.

And this past week’s storms also badly flooded smaller rivers that don’t frequently overflow, catching people off guard.

“I don’t think people have a personal experience with floods like this very often,” said Nathan Young, associate director of the Iowa Flood Center.

In 2022, the average annual price of federal flood insurance was $935. Federally backed mortgages and many banks require flood insurance in high-risk zones identified by the Federal Emergency Management Agency, but those maps don’t consider flooding from all sources, like rain. FEMA’s recently updated pricing reflects more factors, and the agency says these prices — not flood maps — are the best indicator of risk.

The National Flood Insurance Program covers up to $250,000 for a building and offers policies to protect contents worth as much as $100,000. That’s not always enough to replace an entire destroyed house, and even though the private market is small, it provides policies that can fill the gap.

There is some help available for the uninsured. The federal government’s disaster declaration for parts of the flooded area allows it to issue grants and low-interest loans to help with temporary housing, some home repairs and essentials, like cleaning supplies and baby formula.
