Summary

In the City of Waterloo, Iowa, trees and shrubs growing over streets or public property must be trimmed by the adjacent property owner so branches never hang lower than eight feet above the sidewalk, roadway or alley, per Waterloo City Code section 7-5-4. The same eight-foot clearance applies to trees on private property.

All trees or shrubs growing now or hereafter on private property in the city shall be kept trimmed and pruned by the property owner. In no case shall the branches be less than eight feet (8') above the sidewalk or traveled portion of the roadway or alley.

Full Breakdown

Waterloo City Code section 7-5-4 splits trimming duties between public and private property but sets the same clearance standard for both. On public property, subsection A.2 requires the adjacent property owner to trim and prune trees or shrubs growing in the streets or on public property so that branches never hang less than eight feet above the sidewalk or the traveled portion of the roadway or alley. Subsection B.2 imposes the identical eight-foot rule for trees and shrubs on private property. Beyond clearance, subsection B.1 makes it unlawful for a private property owner to maintain trees or shrubs under circumstances that create a hazard.

The city forester directs corrective action whenever a tree or shrub on public property grows in conflict with the chapter or the Waterloo tree and shrub care guidelines (subsection A.1), and any utility company must obtain the forester's written permission before treating, trimming, pruning or removing a tree in a street or public place, with work limited to what the utility actually needs to maintain service (subsection A.3).

Violations & Fines

Failing to maintain the eight-foot clearance, or letting a tree or shrub become a hazard, is enforced as a municipal infraction under section 7-5-8, punished per subsection 1-3-2C of the code with a civil penalty capped at the state-law maximum. The city forester can also order a hazard tree removed under section 7-5-2(B)(1) if the owner does not correct the condition after a complaint under section 7-5-6.
