The main purpose of this legislation is to extend the National Flood Insurance Program (NFIP) until November 21, 2025. The NFIP is a federal program that provides flood insurance to property owners, renters, and businesses in participating communities. By extending this program, the legislation aims to ensure that individuals and communities continue to have access to affordable flood insurance, which is critical for protecting against financial losses due to flooding. Key provisions of the legislation include amendments to two specific sections of the National Flood Insurance Act of 1968.
