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 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. 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. 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.
During cyclic trimming established trees are trimmed to a minimum height of 14 feet over roads and driveways and 8 feet over sidewalks. 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 also trims trees throughout the Village year round. This trimming may be due to storm events, pro-active elimination of issues observed by staff or in response to a request from residents or businesses. "Area Trimming" of larger diameter trees is done annually by a contractor on a rotating basis throughout the Village.
