shade tree, three (3)-inch caliper minimum, shall be installed for every 10 inches of heritage tree caliper removed and shall be in addition to and supplement the “perimeter buffer area” and/or the street tree planting requirement in accordance with Article O Landscaping & Tree Protection as part of the approved subdivision plan. C. Preserving Existing Heritage Trees . As an alternative to “A” and “B” above, if an existing heritage tree is preserved for each existing heritage tree that is removed within the perimeter buffer area or within the site, then the replacement requirement shall not apply. D. Identifying Heritage Trees with a Forest Management Plan . Prior to any execution of a forest management plan or clear-cutting operation, the property owner/developer shall submit a general location map of existing heritage tree(s) within the perimeter buffer area to the Town. However, if a forest management plan or boundary map is submitted to the Town indicating that the perimeter buffer area shall not be disturbed other than necessary access, than a location map of existing heritage tree(s) within the perimeter buffer area shall not be required. The location map will include the species and size in caliper and should be prepared by a professional in the field of horticulture such as a landscape architect, arborist or registered forester. The Town may conduct a field survey to verify the location, species and size of the heritage tree(s). Once the activity begins the perimeter buffer area must remain undisturbed until a site plan or major subdivision has been approved by the Town. E. Replacement of Required Trees . If, in the event, a proposed site plan or subdivision plan, regardless of the acreage, has difficulty locating the required number of trees to replace the removal of heritage tree(s) on a proposed plan, then the property owner/developer may request a review before the Town Board of Commissioners to consider an adjustment to the number of replacement trees required. The adjustment shall be based on topography, property shape, or other existing physical conditions or requirements of the Land Development Ordinance, which impacts the development of the site. Such adjustment shall not have the effect of nullifying the intended purpose of the Clear-Cutting & Protection of Heritage Trees Regulations. (3) Required Grading Plan in Perimeter Buffer Area . Grading (cuts or fills) shall not be permitted within the perimeter buffer area without approval of a grading plan by the Town prior to Wake County issuing a grading permit. Where grading does occur within the “perimeter buffer area” in accordance with a n approved grading plan, no grading shall be extended into the perimeter buffer area more than one- half (1/2) the width of the “perimeter buffer area”.
