Summary
Hartford's zoning code sets minimum branch clearance for street trees: 8 feet over sidewalks and 15 feet over streets, so trimming keeps that space open.
Clear Branch Height. The clear branch height of a tree is the distance between the ground plane and the lowest branch of the tree at maturity. Minimum clear branch height is 8 feet for the portion of trees overhanging sidewalks and 15 feet for the portions of trees overhanging streets. At planting, minimum clear branch height of 5' is required with 6' preferred for all trees planted adjacent to a sidewalk or street.
Full Breakdown
Under the 2022 Zoning Regulations' street tree standards, the clear branch height, the gap between grade and a tree's lowest branch at maturity, must reach at least 8 feet for the portion of a tree overhanging a sidewalk and 15 feet for the portion overhanging a street. At planting, a minimum 5-foot clearance is required (6 feet preferred). All tree trimming and pruning citywide must be performed by or under an ISA-certified arborist per § 6.5.1(F), and topping is banned.
Violations & Fines
Street trees are inspected for compliance by the city (§ 6.5.1(E)); trees maintained below the required clearance are an ongoing landscaping violation the owner must correct, since maintenance duty runs with the property under § 6.5.1(C).
