Iowa City, IA Landscaping Rules: Tree Trimming (2026)

City Code Title 10, Chapter 8 governs trees and plant materials on and near public places. Section 10-8-6 declares that any tree or plant material "so placed as to substantially interfere with pedestrian or vehicular traffic is a public nuisance," and separately singles out cotton-bearing cottonwood and other poplar trees as a nuisance under state law. Section 10-8-7 puts the trimming duty on the abutting owner: trees or plant materials on public or private property next to a street or public place must be trimmed to a sufficient height to allow free passage of pedestrian and vehicular travel, measured against standards the city forester establishes under section 10-8-2's forestry administration authority.

The city forester, appointed by the city manager or designee, sets the specific clearance standards referenced in 10-8-7 and can require correction under section 10-8-9 when planting or growth violates them; if an owner does not remove or replant as directed, the city can do the work itself and assess the cost against the property in the same manner as a property tax under Iowa Code chapter 364. Work on a tree or plant material located on a street or public place, including trimming performed by a utility crew, requires a permit from the city forester under section 10-8-11, and utility work is subject to forester inspection at the utility's cost.

Section 10-8-10 lets the forester issue broader arboricultural specifications covering trimming, planting, spraying, and removal for all public trees and plant materials, and section 10-8-12 bars anyone from interfering with the forester's enforcement of the chapter.
