## Summary

**Would create a HUD grant program to reduce extreme heat in low-income urban neighborhoods.** It would prioritize high-heat, low-tree-canopy census tracts and fund projects like tree planting, cool roofs, and cooling centers. - Families and residents in covered census tracts would get priority for cooling projects, with at least 75 percent of grant dollars directed to eligible high-poverty tracts, increasing local access to shade, cooling centers, and cooler pavements. - Local governments, Indian tribes, metropolitan planning organizations, and territorial governments could receive grants under a federal matching framework that defaults to an 80 percent federal share and allows a waiver up to 100 percent for economic hardship. - Nonprofits and community groups can get technical assistance capped at 3 percent of program appropriations and compete for funds that support tree planting, urban forestry plans, canopy assessments, arboriculture training, maintenance, and other heat-mitigation actions; an oversight board may use up to 5 percent of program funds to evaluate progress. *Authorizes $30 million annually from 2026 through 2033 to carry out the program, increasing federal spending over that period.*
