About the Program
As part of its Climate Action Plan Framework, the city of Phoenix aims to create a safe and environmentally conscious network of cool corridors across its communities. This is part of a multi-point climate strategy that aims to encourage safe movement from residential homes to various areas across the city.
The Street Transportation Department implemented the cool corridors program in 2022 with the approval of $1.4 million to assist with planting up to 200 trees per mile for a total of 1,800 new trees planted across project areas citywide. The department's Cool Corridors program is a part of Phoenix's more comprehensive Tree and Shade Master Plan and is supported by continuous research, prioritization and assessment through a partnership with Arizona State University and other partners.
Identifying and Prioritizing
City staff and researchers developed data using four variables to develop a ranking system. The rankings are used to identify candidate areas in the city to determine where tree planting investments will be most valuable. The four ranking criteria are:
- Neighborhood heat vulnerability,
- Transit dependency,
- Pedestrian use, and
- Shade coverage and temperature
Education and Community Outreach
Cool Corridors are one-quarter to half-mile segments, walkways or trails adjacent to an arterial street designed to keep pedestrians, bicyclists and transit users safe and provide relief from the high temperatures of our urban desert landscape. Cool Corridors can have natural and engineered shade, combined with other temperature-lowering design features that can be achieved through public and private partnerships and resources.Interactive Cool Corridors Map
