1. A tree preservation plan shall be required for all soil disturbance activities where Tree Preservation and Mitigation Standards apply. A tree preservation plan shows how the Tree Preservation and Mitigation Standards will be met and how preserved trees will be protected during construction and other potentially harmful activities. 2. The tree preservation plan shall be based on the tree survey. 3. If a tree survey shows that no significant trees are on the development property or adjacent properties are near the construction area, the City may waive the tree preservation plan requirement. 4. A tree preservation plan shall identify: a. The basic use area and environmentally sensitive areas. b. The disturbance area. c. Tree size (DBH), species, condition, location, and root protection zone for all significant trees to be preserved, or; d. The combined root protection zone of all stands of trees designated for preservation, whichever is applicable. e. Location and type of tree protection fence. f. Staging areas. g. Temporary construction access routes when temporary site access is necessary within root protection zone of any tree or tree stand designated for preservation. i. Temporary access shall be routed in a manner that is least disruptive to the tree or tree stand per the approval of the City Forester. 11. Temporary access roads shall not exceed 25 feet in width and shall be delineated by snow fencing or safety fencing. 111. An eight (8) inch deep cover of wood chip mulch shall be placed over the temporary access route to cushion the root protection zones from compaction. h. Concrete washout areas. 1. Existing and proposed grading. j. The plan shall show directional felling and trenching to separate root systems prior to bulldozing trees or stumps if necessary to avoid damage to adjacent trees. 115
