• Tree protection barrier requirements

  All areas of tree protection shall be bounded by a tree protection barrier at the perimeter of the tree protection zone. Barriers shall completely surround the tree protection area, except where the area extends more than one hundred (100) yards beyond the construction zone or routes of access to the construction zone. The tree protection areas, beyond the one hundred (100) yards, shall be flagged every one hundred feet (100') with continuous ribbon with 'Do Not Enter' signs stating prohibited activity. Barriers and flagging shall be installed prior to any land disturbing activity. Barriers shall be a minimum of five feet (5') in height, stationary, and constructed of rigid or semi-rigid materials that must be dismantled to be moved.

• Clearing method

  Any clearing within tree protection zones shall be done by hand.

• Tree damage repair

  Any damage done to trees within tree protection zones shall be immediately repaired.

• Grade difference handling

  Where grade differences occur between the tree protection area and the finished grade of the adjacent areas, retaining walls and dry wells shall be used to prevent the need for grading in tree protection zones.

• ProhibitedProhibitedNot allowed in the district at all, short of rezoning or a variance. activities in tree protection zones

  The following activities are prohibited within tree protection zones: (1) Operation of any vehicle or machinery, except as may be necessary for the installation of utility lines.

• Utility routing in tree protection zones

  Wherever feasible, utilities shall be designed and routed to avoid tree protection zones. If it is necessary to route utilities through tree protection zones, the following shall apply: (1) Route utility trenches outside the drip line of trees or as far as possible from tree trunks. (2) In areas of multiple trees, where trenches must go between trees, preference should be given to stay away from larger specimen trees. (3) Equipment that is the lightest weight and makes the least possible impact shall be used to dig trenches and install utilities. (4) Rubber-tired, rather than track equipment, shall be used whenever possible. (5) Excavation materials are not to be placed against tree trunks and shall be placed as far away from trunks as possible. (6) Where excavation materials are to be placed, indicator ribbons shall be placed on undisturbed areas prior to excavation, to facilitate restoring the area to the original grade. (7) Areas where excavated materials have been placed shall be restored to the original grade with the least amount of disturbance possible.
