Parkway Tree Trimming

Public safety is the Village's first priority when trimming trees, followed by tree health and then aesthetics. Street trees have different maintenance requirements than landscape trees and are pruned accordingly. Normally no more than one-quarter to one-third of the live crown will be removed at one time. The determination of how much to remove is dependent upon tree species, size and condition of the tree, as well as the duration between trim cycles. The Village tries to maintain a 6-year trim cycle for trees greater than 6 inches in diameter and a 3-year cycle for smaller diameter trees. The shorter the trimming cycle, the less live material needs to be removed resulting in less stress to the tree. The natural form of the tree is maintained as much as possible, with tree growth directed upward and outward.

Established trees are trimmed to a minimum height of 14 feet on all sides. This allows for safe clearance by all vehicular and pedestrian traffic. It also ensures that any signage in the parkway is clearly visible. The remaining extent of trimming includes the removal of deadwood, removal of diseased, insect infested, broken, hanging, weakly attached, or structurally unsound limbs, correction of storm damage, thinning of sucker growth, removal of limbs which interfere with utility lines, street lights or vegetation on private property and removal of limbs which conflict with other limbs.

The in-house Forestry crew trims smaller parkway trees throughout the Village year round. This proactive trimming allows for a gradual raising of the crown, correction of defects early in the tree’s life and smaller pruning wounds which close more quickly. "Area Trimming" of larger diameter trees is done annually by a contractor on a rotating basis throughout the Village. See the Area Tree Trimming Map for areas that are currently being trimmed.
