FEMA data, assembled by Value Penguin, found that properties in Louisiana are most at-risk for flooding, but a broader model suggests a surprising state—West Virginia—would be the hardest hit.
The data reported that West Virginia has the highest percentage of homes that would be impacted in a 100-year storm (29.3%), as Louisiana reported the highest share of homes in FEMA’s Special Flood Hazard Areas (23.5%).
FEMA and the First Street Foundation models identify areas of risk of flooding as those with at least a 1% chance of being seriously impacted by a flood event in any given year—referred to as a base flood or 100-year flood.
First Street Foundation’s model found 16.5 million properties at-risk, compared to the 8.4 million from FEMA’s classification.
Data from the two reports vary, as FEMA found 3.2% of Hawaii properties are in a flood hazard area, which is drastically less than 26.1% found in the First Street Foundation model.
The report added that Louisiana expects to experience the biggest jump in the share of homes facing a flood risk due to rising climate change concerns.
In Louisiana, 24.5% of properties are at-risk for flooding, according to First Street Foundation. This is expected to increase to 38% in 30 years. Florida, which has the second-highest increase in flood risk, may increase to 26.6% from 23.3%.
Flood concerns have been top-of-mind in Washington, as the U.S. Senate Committee on Banking, Housing, and Urban Affairs recently held the session, “Reauthorization of the National Flood Insurance Program: Administration Perspectives.”
Sen. Sherrod Brown, Chairman of the Senate Banking Committee, and Ranking Member Patrick J. Toomey heard testimony from David I. Maurstad, Federal Emergency Management Agency Associate Administrator for Resilience (Acting) and Senior Executive of the National Flood Insurance Program (NFIP).
The NFIP provides more than $1.3 trillion in coverage to nearly five million homes and businesses in over 23,000 communities. The NFIP provides flood insurance to property owners, renters, and businesses, and having this coverage helps them recover faster when floodwaters recede.
Natural disasters and climate risk events such as flash flooding in West Virginia and Alabama; flooding in Montana and Yellowstone National Park; ice jam flooding in Alaska; heavy rainfall flooding in Arkansas and Oklahoma; and heavy rain, snowmelt and ice jam flooding in North Dakota and Minnesota have already impacted thousands of homeowners this year, well before hurricane season has begun.
“The NFIP combats the overall threat of flooding through four related components: Flood insurance; floodplain management; floodplain mapping; and mitigation,” said Sen. Sharrod Brown in calling for more to be done for those in high-risk areas. “The Bipartisan Infrastructure Bill offers a down payment on new opportunities for communities to help homeowners stay out of harm’s way. But we need to do more. Infrastructure investment was a good start. But because of climate deniers in the Senate and our collective failure to fight climate change, that investment in the infrastructure bill will not be enough.”
FEMA personnel are already preparing for the 2022 Hurricane Season, expected by The National Oceanic and Atmospheric Administration to be above-normal for activity, as CoreLogic’s recently released 2022 Hurricane Report—which analyzes hurricane and storm surge and wind risk exposure for and multifamily residences (MFRs) along the U.S. Gulf and Atlantic Coasts—found that nearly 7.8 million homes with more than $2.3 trillion in combined reconstruction cost value (RCV) are at risk of hurricane-related damages this upcoming season.
On September 30, 2022, the NFIP’s statutory authority to sell and renew flood insurance policies is set to expire. Since the NFIP’s last multi-year reauthorization expired on September 30, 2017, the NFIP has experienced several short-term extensions and three brief lapses. The short-term extensions have been found to be disruptive and cause existing and potential policyholders to lose confidence in the NFIP.
