The purpose of this legislation, known as the Preventing Our Next Natural Disaster Act, is to improve measures that help communities prepare for and mitigate the impacts of natural disasters. The goal is to reduce the damage caused by future disasters through better planning and investment in preventive measures. Key provisions of the Act include several important updates to existing disaster relief laws. It defines terms like "high hazard risk" and "environmental justice community," ensuring that these definitions guide how assistance is provided.
