The main purpose of this legislation is to extend the National Flood Insurance Program (NFIP), which provides flood insurance to property owners in the United States. The objective is to ensure that this program continues to operate and provide financial protection against flood-related damages for an additional period. Key provisions of the legislation include the reauthorization of the NFIP until September 30, 2025. This means that the program will continue to be funded and operational for two more years.
