<br />Page 11 <br /> <br />a. Roots1-inch in diameter or larger to be removed shall be cleanly cut with a hand saw. <br />Roots smaller than 1-inch in diameter are not considered to be significant and may be <br />removed by the most efficient means. <br />b. Roots larger than 2-inches in diameter and within 8-feet of the tree trunk shall not be cut <br />or ground unless prior approval has been received from the Landscape Architecture <br />Division. <br />c. Roots of any diameter farther than 8-feet from the tree trunk, which are in conflict with <br />the proposed work may be ground a maximum of one-half of their diameter. Work of this <br />nature shall only be performed using a mechanical stump grinder and only by personnel <br />familiar with its operation. <br />d. Roots up to 6-inches in diameter and farther than 8-feet from the tree trunk may be <br />removed if they are in conflict with the proposed work. Roots that are removed shall be <br />cleanly cut using a hand saw. <br /> <br />61. ROOT CONTROL BARRIER: The applicant shall provide root control barriers and 4-inch <br />perforated pipe for all trees located within 8-feet of pavement or other hardscape, determined by <br />the City Landscape Architect. Root barriers shall be located along the edge of the pavement <br />wherever the tree is within 8-feet of pavement or hardscape. Information and details shall be <br />included in the landscape plan submittal for review and approval by the Landscape Architecture <br />Division. <br /> <br />62. TREE PRUNING: Pruning shall be conducted by a certified arborist familiar with the <br />International Society of Arboriculture (ISA) pruning guidelines and shall comply with the <br />guidelines established by the ISA, Tree Pruning Guidelines, current edition, to maintain the <br />health of the trees. <br /> <br />63. TREE PROTECTION FENCING: Prior to issuance of a grading or building permit, the applicant <br />shall install temporary 6-foot-tall chain-link fencing (or other fence type acceptable to the <br />Landscape Architecture Division) outside of the existing tree drip lines. The location of the tree <br />protection fencing shall be shown on the demolition plans (if applicable), grading, building, <br />and/or landscape plans. The fencing shall remain in place until final landscape inspection by the <br />Landscape Architecture Division. Removal of such fencing prior to approval may result in a “stop <br />work order.” <br /> <br />64. PROJECT PLANS: The following statements shall be printed on the demolition, grading and <br />landscape plans where applicable to the satisfaction of the City Landscape Architect prior to <br />issuance of building permits: <br /> <br />a. No existing tree may be trimmed or pruned without prior approval by the City <br />Landscape Architect. <br />b. Utilize best efforts to locate any new utility trenches outside of the existing <br />canopy of the trees to be saved. If this is not feasible, the applicant shall submit a <br />report from a certified arborist acceptable to the City indicating trenching will not <br />be detrimental to the health of the tree. <br />c. Nothing may be stored within the dripline of the tree canopies. This includes <br />equipment, oil, gas, chemicals, harmful materials, fill or storage. <br />d. No oil, gasoline, chemicals, or other harmful materials shall be deposited or <br />disposed within the dripline of the trees or in drainage channels, swales, or areas <br />that may lead to the dripline. <br />e. No sign, wires, or ropes shall be attached to the trees.
