This bill, titled the "Repeatedly Flooded Communities Preparation Act," amends the National Flood Insurance Act of 1968 to enhance community accountability for areas experiencing recurrent flood damage. It establishes requirements for specific "covered communities" that have a significant number of repetitive loss structures , severe repetitive loss structures , or public/private nonprofit facilities repeatedly damaged by floods. The primary goal is to foster proactive flood risk mitigation at the local level. The legislation mandates that these covered communities must identify their repeatedly damaged areas, assess ongoing risks, and develop a comprehensive, community-specific plan to mitigate these flood risks. These plans, along with any updates and progress reports, must be submitted to the Administrator and made publicly available. To support these efforts, the Administrator is directed to provide necessary data and may prioritize mitigation grants for compliant communities actively working to address their flood problems. Should a covered community fail to comply with these requirements or make sufficient progress in reducing flood risks, the Administrator is authorized to impose sanctions. These sanctions can include suspension or probation from the National Flood Insurance Program. Before imposing any penalties, the Administrator must provide notice of the violation, including recommendations for corrective actions, and consider the community's available resources and challenges in mitigation. The bill also requires the Administrator to submit regular reports to Congress detailing the progress of covered communities.
