Flood Insurance Program Expiry Threatens Millions of Homeowners

Millions of American property owners are anxiously waiting as the National Flood Insurance Program (NFIP), a federal initiative that provides vital flood insurance coverage, faces potential expiration at the end of September. The program, which needs Congressional reauthorization for continuity, has been a lifeline for homeowners in high-risk flood zones who are mandated to have flood insurance, especially those purchasing properties with government-backed mortgages. However, experts are questioning whether simply renewing this imperfect program will be sufficient to protect homeowners in the face of increasing climate change-induced natural disasters.

The stakes are high, with the NFIP currently covering approximately 4.7 million properties, and another 8 million properties across the U.S. in flood-risk zones potentially relying on private flood coverage or lacking any insurance at all. If Congress fails to reauthorize the program, homeowners may be forced to turn to private insurers, potentially facing significantly increased costs. These properties are often located near river channels with a history of flooding, or in areas impacted by precipitation flooding, and the risk of loss is only increasing as climate change fuels more frequent natural disasters.

Critical Flood Insurance Program Faces Expiry Amid Rising Climate Threats

NFIP at Risk of Expiry

The National Flood Insurance Program (NFIP), a pivotal federal program that insures millions of properties, is due to expire by the end of this month. Experts anticipate that Congress will reauthorize the program, but also express concerns about whether the renewal of what they regard as a flawed program will suffice to aid homeowners.

The NFIP needs to be reauthorized by Congress by the end of September to ensure that home buyers can finalize their purchases with new policies. Buyers who acquire properties with government-backed mortgages in high-risk flood zones are mandated to possess flood insurance.

As Climate Risks Increase, NFIP Remains Vital

The NFIP currently covers about 4.7 million properties. According to Jeremy Porter, the head of implications research for First Street Foundation, there are 8 million properties across the U.S. situated in flood-risk zones that may depend on private flood coverage or lack any insurance at all. These properties are typically located near river channels with a history of flooding or in areas impacted by precipitation flooding.

With natural disasters increasing due to climate change, more homeowners are at risk of losing their properties. For example, more than 1.2 million homes in California are at moderate or high risk of wildfire damage. Nationally, over 33 million homes are at risk for damage from hurricane-force winds or coastal exposure, which exposes them to storm-surge flooding.

NFIP’s Shortcomings and Future Reforms

Despite its necessity, the NFIP has several issues. Some homeowners are undercharged for premiums, and the program has been criticized for its unreliable flood risk mapping. There have been calls for reforms such as increasing funding to help FEMA better map, identify, and reduce flood risks, creating oversight measures for insurers and vendors, and providing FEMA with more authority to sever ties with contractors that misuse the system.

FEMA has launched a new "Risk Rating 2.0" methodology to improve the assessment of a property’s likelihood of flooding. However, this new approach has faced significant opposition, particularly in southern Louisiana where homeowners are slated to see steep premium hikes.

Despite these controversies, premiums under the new methodology still fall below what a private insurer would require to be profitable, due to statutory limits on premium increases for policyholders of no more than 18% per year.


The looming expiry of the NFIP underscores the critical role of federal programs in managing the increasing risks posed by climate change. While the NFIP has its shortcomings, it remains a vital safety net for millions of homeowners in flood-prone areas. Reauthorizing and reforming the NFIP should be a priority for Congress, particularly in light of the increasing frequency and severity of natural disasters. As we move forward, it’s crucial to strike a balance between ensuring affordable coverage for homeowners and accurately reflecting the risks posed by climate change.
