Establish a national urban forestry program requiring cities above 250,000 population to develop 10-year canopy expansion plans with binding milestones, prioritizing neighborhoods identified through spatial analysis of canopy deficit, surface temperature anomalies, and socioeconomic vulnerability.

Federal grants fund planting at $800-1,200 per tree including 5-year maintenance, with performance-based allocations for cities meeting interim targets. Program design mandates species diversity, community engagement, and long-term maintenance commitments.
