Cool Corridors Act of 2025

The Cool Corridors Act of 2025 reauthorizes and expands the existing Healthy Streets program to make transportation corridors cooler, safer, and more accessible. By emphasizing tree canopy, shade infrastructure, and other nature-based cooling strategies along pedestrian, bicycle, and transit routes, the bill aims to reduce extreme heat, improve safety for users, and extend infrastructure lifespans. It prioritizes investments in communities with high heat exposure or limited tree cover and expands the pool of eligible grantees to include state and local transit agencies, transportation departments, local school districts, and tree/greenspace stewardship groups. The act also adds requirements for planning, maintenance, monitoring, and reporting, and requires coordination with multiple federal agencies. In effect, the bill would extend funding through 2030, broaden who can receive and implement projects, mandate ongoing evaluation and interagency coordination, and emphasize locally driven, equitable heat-mitigation efforts along public transit corridors, including bus stops and school zones.
