The main purpose of this legislation is to extend the National Flood Insurance Program (NFIP), which provides flood insurance to property owners, renters, and businesses in flood-prone areas. The NFIP was originally established to help communities manage flood risks and ensure that residents have access to affordable flood insurance. Key provisions of this legislation include extending the financing and program expiration dates of the NFIP. Specifically, it changes the expiration date from September 30, 2023, to September 30, 2025.
