Full Breakdown
Municipal Code section 19-40 requires property owners to keep street trees adjoining their property, and all private trees, trimmed to a height of not less than 12 feet over a street or alley and not less than 10 feet over the parkway and sidewalk. Section 19-59(A) restates and sharpens that duty in the context of obstructions: anyone owning or occupying property bordering a street with trees on it must prune so the trees don't obstruct or shade streetlights, block pedestrian passage on sidewalks, obstruct traffic signs, or block visibility at intersections, with a minimum clearance of 10 feet over sidewalks and 12 feet over streets generally, but 16 feet over truck thoroughfares.
Routine watering and trimming responsibility for street trees falls on the adjoining property owner under section 19-39, unless a homeowners' association or assessment district has taken it over, and all pruning must follow ANSI A300 pruning standards under section 19-41, with the director keeping a copy of those standards available for review. If an owner doesn't prune as required, section 19-59(B) has the director issue written notice by certified mail giving 10 working days to comply.
Violations & Fines
If a property owner fails to prune within the 10-working-day compliance window after certified-mail notice under section 19-59(B) and (C), the city performs the pruning itself and assesses the exact cost against the owner as a special assessment, collected with the same penalties and interest as delinquent property taxes, under section 19-59(D). Failing to maintain the required clearance can also expose the responsible party to liability if someone is injured as a result.
