Federal Flood Risk Management Act of 2024

This bill establishes a Federal Flood Risk Management Standard requiring federal agencies to consider flood risks in planning and construction of federally funded projects. It mandates that agencies use climate-informed science to evaluate flood risks, requiring new construction to be elevated 2-3 feet above base flood elevation (depending on whether it's a "critical action"), and requires agencies to consider alternatives to building in floodplains. The law also requires agencies to provide public notice and allow for comment on projects in floodplains, and to annually reassess implementation based on the latest science. These requirements apply to all federal agencies undertaking actions in or affecting floodplains, including construction, improvements, and planning activities involving federal funds.
