The property owner, developer, contractor, and/or authorized agents shall make every effort to protect those trees to be preserved during site preparation and construction. To this end, the following methods and procedures shall be followed:
(A) The use of hand labor may be necessary to clear vegetation within the drip line of those trees to be preserved. This shall be determined by the City Planner at the time of barricading as described below.
(B) Materials, machinery and soil shall not be placed within nor use the area within the drip line of any tree to be preserved.
(C) Materials, wires, signs, or nails shall not be attached to any tree unless such materials are used to preserve the tree.
(D) All felled material shall be promptly and carefully removed from the site in order to avoid potential damage to remaining trees and vegetation.
(E) Visible barricades shall be erected around those trees to be preserved. These barricades shall be at the drip line of the tree(s) and no closer than ten (10) feet to the trunk of the tree.
(F) All trees to be preserved, except palms, shall have their natural soil level maintained. Tree wells and/or retaining walls shall be provided where necessary to maintain the natural existing soil level. The design of these structures shall be approved by the Planning Director and shall generally be consistent with methods specified in Tree Protection Manual for Builders and Developers, published by the Florida Department of Agriculture and Consumer Services, Division of Forestry, latest edition.
(G) All efforts shall be made through the grading and drainage plan to maintain the natural drainage to those trees to be preserved. Swaling and minor negative grade changes should always be designed outside the drip line area as much as possible. Piping should be used where deep swales or ditches would require significant grade changes adjacent to trees to be saved. Trenching of any type should be avoided in the drip line area. Where underground installations are required adjacent to the trunks of trees to be preserved, tunneling should be used. When trenching or tunneling near trees to remain, protective measures should be taken as specified in Tree Protection Manual for Builders and Developers.
(H) All trees not approved for removal shall be protected and maintained during construction, as specified in the Tree Protection Manual for Builders and Developers or other comparable publications approved by the Planning Division.
