Tempe, AZ Tree Protection: Tree Replacement Requirements (2026)

Tempe requires tree replacement as part of its landscape standards in the Zoning and Development Code. When significant trees are removed during development or redevelopment, replacement planting is typically required. The replacement may be at a ratio greater than 1:1 for large or mature trees. Replacement trees should be desert-adapted species from the city's approved plant list, with emphasis on shade-producing canopy trees for urban heat island mitigation. Common recommended species include mesquite, palo verde, desert willow, and other native or adapted shade trees. The city's tree replacement standards are evaluated during the landscape plan review process. City street trees damaged by adjacent property owners must be replaced with approved species at the owner's expense. Tempe's urban forestry program actively works to increase canopy cover, particularly in heat-vulnerable areas and along pedestrian corridors. The city may require tree protection fencing during construction to preserve existing trees that are being retained.
