Stakes shall not penetrate the root ball and shall be driven into the ground approximately twenty-four to thirty (24"-30") inches below grade. h. Clean up all trash and any soil or dirt spilled on any paved surface at the end of each working day. viii. Stump Removal Contractor crew grinds stumps to a depth of eighteen (18") inches. All holes will be backfilled; as well as all debris cleaned up and hauled away. The City is responsible for marking trees so that they are easily identifiable by Underground Service Alert and the Contractor. The Contractor shall be required to call Underground Alert at least 2 days before stumps are to be ground out. All tree stumps must be removed to at least 18 inches below the lowest soil level adjacent to the stump, or until deep roots are no longer encountered. The Contractor shall grind the stump a minimum distance of one and a half (1%') feet either side of the outer circumference of the stump, or until surface roots are no longer encountered. Stumps should be cut low enough to the ground where routing can be done safely. This may be accomplished by cutting the stump at the time of grinding, or at the time of tree removal except for infrastructure conflicts. Holes created by stump and root grinding must be filled the same day. The resultant chips from routing may be used to fill the hole to two (2") inches above normal ground level. All excess routing chips debris will be removed and loaded into transport vehicle for disposal. Any damaged paved surfaces shall be restored to their original condition. ix.
