Before construction, grading or land clearing begins; trees or tree areas that are to be preserved shall be visibly marked and the city-approved tree protection fencing or other method shall be installed and maintained at the critical root zones of the trees to be protected. The location of the fencing shall be in conformance with the approved tree preservation plan. This fencing shall be inspected by city staff before site work begins. B. During Construction. The following activities shall be prohibited within the critical root zone areas of trees to be protected. 1. Trenching; 2. Temporary storage of any construction materials or chemicals; and 3. The routing or parking of heavy equipment, including cars, trucks, bulldozers and construction trailers. 4. Sediment and erosion control. All sediment and erosion-control silt fencing or straw bales shall be placed at the limits of grading or where needed to minimize the deposition of sediment within the drip line of the protected tree(s). 5. Attaching protective devices, signs, etc., to trees is prohibited. No protective devices, signs, utility poles or lines, or other objects shall be nailed or attached to any trees that are to be preserved. 6. Other actions prohibited. Any other action within the drip line of the protected tree(s) that may result in the severing of roots or compaction of soil, or that may impede the free access of air and water to tree roots, shall be prohibited. C. Ponding. Water retention ponding may not be located where there are significant trees, unless approved by the city. The water retention ponding must be created in a manner that prevents erosion into any nearby water resource. D. Amendments to Plan. An amendment to the tree preservation plan shall be required prior to the removal of trees that were designated for preservation on the original tree preservation plan. The amendment shall be subject to City approval prior to implementation.
