Summary of Specifications:
Various and numerous trees throughout the City of Pontiac have been identified for removal. All trees that are identified for removal are within the City right-of-way or on City owned property. The right-of-way shall be defined as the area between the curb and sidewalk. If no sidewalk exists, the contractor shall request instruction from the City as to the right-of-way limits.
All trees shall be removed in their entirety. All tree trunks, limbs, leaves, twigs, sawdust and chips resulting from the removal operations will be totally removed and disposed of from the work site on a daily basis by the contractor. Street and sidewalk areas shall be swept and all other areas shall be raked clean of debris generated through removal operations.
Stumps and all visible surface roots shall be mechanically ground out to a minimum depth of 8 inches below the surrounding grade. For locations where sidewalk and curb exist, the surrounding grade shall be established by means of an imaginary line extending from the top of the curb to the street side edge of the city sidewalk. All excess stump chips shall be physically removed from the sites. Sufficient stump chips shall be left on site to fill the resulting depression slightly above the surrounding grade (to allow for some settlement).
3.2.18 Trees shall be pruned by removing all dead, diseased, broken and crossing branches. Trimming shall be done by the “drop crotch” method. No stubs over one inch (1”) shall be permitted when completed. Live braches shall be removed only to maintain the natural shape and appearance of the trees. A collar should be maintained on lateral branches. Flush cuts are to be avoided on larger branches.
