When Congress passed the 2012 Biggert-Waters Act, the goal was to keep the National Flood Insurance Program afloat after insurance payouts from several devastating hurricanes, including Katrina, left the program in debt. However, lawmakers did not foresee the legislation’s impact on Louisiana homeowners: sky-high flood insurance premiums for some of the same families that had already suffered through the “single most catastrophic natural disaster” in U.S. history. The Biggert-Waters Act hit some Louisiana families with annual premiums as high as $18,000 and threatened to destabilize the state’s property values and housing market.

Waters Act despite its harm to Louisiana homeowners. Although opposition from conservative groups like AFP caused House leaders to delay a vote on the fix, Congress passed the Homeowner Flood Insurance Affordability Act in March 2014, staving off Biggert-Waters’ extreme premium hikes despite the Koch Brothers’ efforts.
