On the day damage is inflicted, trim any limbs or branches of trees broken during construction operations with a clean cut, and paint with an approved tree pruning compound. Treat tree trunks receiving damage from equipment with a tree dressing. B. Protect living shrubs and trees not marked for removal and outside the rights-of-way or easement area by erecting appropriate temporary barricades around the drip line of said trees and wrapping with burlap as necessary for protection during the construction period; method subject to approval by the City Engineer.
