(A) Due care shall be exercised to avoid injury to existing sewer improvements or facilities, streets, highways, pavements, utility facilities, adjacent property and roadside trees and shrubbery that are not to be removed.
(B) Trees and shrubbery adjacent to the sewer trench, pole line, fences, signs, survey markers and monuments, buildings and structures, conduits, pipeline under or above the ground, sewer and water lines, all highway facilities and any other improvements or facilities within or adjacent to the sewer work shall be protected from injury or damage and, if ordered by the Engineer, the contractor shall provide and install suitable safeguards, approved by the District to protect such objects from injury or damage. The contractor shall not remove trees or shrubs adjacent to the sewer trench line without authorization by the District and/or other agencies having jurisdictions. No major roots or branches crossing the trench shall be cut if, in the opinion of a qualified arborist, such cutting would seriously injure or imperil the safety of the tree or trench. All limbs, roots or branches which are cut or broken shall be trimmed and coated with the proper seal. If other objects are injured or damaged by reason of the contractor’s operation, they shall be replaced or restored, at the contractor’s expense, to a condition as good as when the contractor entered upon the work, or as good as required by the specifications accompanying these standards.
(C) Roots four inches or greater in diameter encountered by the contractor in the course of excavation shall be exposed but not severed, and, as a protective measure, they shall be wrapped in burlap while exposed. Roots two to four inches in diameter that are severed in the course of excavation shall be neatly trimmed and coated with a heavy coat of an approved tree seal. Should major tree trimming be required, the District may request that the contractor hire a qualified arborist to provide recommendations.
