Excess Urban Heat Mitigation Act of 2025

S 1166, the Excess Urban Heat Mitigation Act of 2025, creates a federal grant program to fund heat-mitigation projects in high-risk urban areas. It directs at least 75% of annual $30 million funding toward "covered census tracts" (areas with poverty rates ≥20%) and prioritizes projects like tree planting, cool roofs, and community cooling centers. Eligible entities must include community engagement plans and address health/environmental connections in their proposals. The program requires annual reporting on grant recipients and sets a federal cost-share cap of 80% (with 100% possible for economic hardship cases).
