§ 157.05 TREE PROTECTION ON DEMOLITION AND/OR PRINCIPAL STRUCTURE CONSTRUCTION SITES.
   (A)   On sites where demolition and construction projects are permitted, all trees not approved for removal must be protected on site and in the parkway by protection fencing. Such fencing shall be secured by thin metal posts driven into the ground at ten foot intervals. The construction envelope for the site must be designated and any pruning to any tree to accommodate construction must be approved by the city and performed by a licensed, bonded, insured tree removal company under the direction of a certified arborist.
   (B)   Site entrances and exits must be approved by the city.
   (C)   Storage and supply areas must be included in plans and approved by the city.
   (D)   Protection of trees shall include protection of all parts of the tree: the crown, trunk and root system:
      (1)   The crown area, its boughs and branches, shall not be damaged or broken by construction or tree removal equipment or building activities. No rope, wires, chains, or building materials shall be attached to any branch.
      (2)   The trunk shall not be damaged, cut, dented, banged, hammered into, or wrapped with wire or have any sign or attachments that may cause bark or the inner growth cambium area to be damaged. Nor shall any construction equipment or supplies be set against or secured to the trunk.
      (3)   The roots of trees shall be protected from trenching, cutting and crushing. No soil shall be added to or removed from the critical root zone unless authorized. No placement of vehicles, driven or parked, construction equipment, supplies, building materials, excess soil, waste, fill, debris, excavation clay or the like shall be placed in the critical root zone of protected trees. Harmful chemicals are not allowed in the critical root zone or in any area that could seep into the critical root zone.
   (E)   Hazardous trees must be removed from the construction site prior to:
      (1)   Construction of the principal structure; and
      (2)   The issuance of temporary and/or final occupancy.
