In 2022, Phoenix’s Street Transportation Department launched the Cool Corridors program to plant trees in targeted transportation corridors to keep pedestrians, bicyclists and transit users safe and provide relief from high temperatures. The focus on equity in the Shade Phoenix Plan and lessons from the first few years of the Cool Corridors program required a reconsideration of its goals and investment plan, which originally called for 1,800 trees to be planted per year and projects across all city council districts. The focus of the program will continue to be increasing shade coverage on highly used walking routes in communities disproportionately impacted by summer heat. However, delivering and maintaining successful Cool Corridor projects in the highest-need areas require a more comprehensive strategy with higher per-project costs. Therefore, the Cool Corridors program will focus on construction and maintenance of exemplary projects in priority communities that address infrastructure deficiencies and conflicts to provide robust shade. When feasible, Cool Corridor investments will align with major construction and capital improvement program projects to maximize impact and efficiency.
