The main purpose of the Wildfire Prevention and Recovery Act is to enhance safety and preparedness regarding wildfires, particularly in Arizona. The law aims to require the Secretary of the Army to conduct assessments that evaluate the risks of wildfires to federally authorized dams, reservoirs, and related infrastructure. This is intended to help reduce the risks and costs associated with wildfires and their aftermath. Key provisions of the Act include the requirement for periodic wildfire risk assessments.
