See below for a list of frequently asked questions about tree pruning in the City Beautiful!
No, residents do not need to personally request pruning of city trees, as they are automatically scheduled by the arborists managing the pruning needs city-wide.
However, on private property, the removal or relocation of any tree 4.5 inches in diameter or larger measured 4 feet from grade requires a permit.
The city prunes trees to increase tree canopy growth and coverage to alleviate heat over paved areas. Tree pruning also provides environmental benefits such as wildlife habitat, temperature cooling, carbon sequestration and water runoff uptake to mitigate flooding.
Trees are generally pruned every 18 months to four years depending on the species, speed of growth and condition of the trees as determined by the arborists on staff.
However, unforeseen circumstances such as extreme weather activity or car accidents can affect the schedule.
Pruning needs are prioritized by certified arborists to maintain the health and resiliency of each tree, and to address safety concerns such as foliage blocking visibility or signs, dead branches, or branches growing too low over sidewalks or roads.
Yes, residents can execute a tree pruning permit using an ISA-certified arborist and upload it to the online permit portal for review by a city arborist.
More information about city trees, and permit applications for tree pruning, removal or relocation is available on our Greenspace Management page.
No, there is no GIS or online mapping program to find the location of tree pruning crew trucks in real time. Internally, the city uses a program called Cartegraph to map assets and keep tree pruning data for internal scheduling.
