This legislation aims to significantly enhance the transparency of the National Flood Insurance Program (NFIP) by requiring the public disclosure of comprehensive program information. It mandates amendments to the National Flood Insurance Act of 1968 to facilitate a better understanding of flood risks and program effectiveness. The bill specifically seeks to position the NFIP as a valuable source of data for research and development in flood risk assessment and predictability. The Administrator is directed to establish an open source data system to make publicly available all data, models, and analytical tools used in assessing flood risk, establishing flood elevations, and determining premiums. This includes individual property risk data , loss ratio information, and current and historical policy and claims data, limited to amount/term or date/amount paid, along with identification of pre/post-FIRM construction and mitigated or unmitigated multiple-loss properties . Additionally, a publicly searchable database for communities participating in the NFIP will detail compliance status, noncompliance findings, enforcement actions, and the number of pre- and post-FIRM properties in special flood hazard areas, as well as total multiple-loss properties . All disclosed information must be formatted to prevent the revelation of individually identifiable information about property owners, ensuring privacy while promoting transparency and identifying properties at the ZIP Code or census block level.
