88 Page 31 ~ Tree Protection Plan: In order to ensure that the trees designated to be retained will survive the construction of the project, the applicant shall fund the preparation of a tree protection plan to be prepared by a certified arborist. The Arborist shall prepare recommendations for appropriate Tree Protection Zones (TPZ) for all trees to be retained, evaluate the potential consequence of impacts on the root systems and from canopy pruning and advise if the trees can be retained, and identify such other measures such as requiring pier and grade beam foundations and adjustments in the siting and footprint of the houses as necessary to ensure the retention of the trees identified to remain on site. The Tree Protection Plan shall include at least the following protection measures: a. Before the start of any clearing, excavation, construction or other work on the site, every protected tree ("protected" means designated to be retained on the project site) deemed to be potentially endangered by said site work shall be securely fenced off at a distance from the base of the tree to be determined by the Arborist. Such fences shall remain in place for duration of all such work. All trees to be removed shall be clearly marked. A scheme shall be established for the removal and disposal of logs, brush, earth and other debris to avoid injury to any protected tree. b. Where proposed development or other site work must encroach upon the protected perimeter of any protected tree, special measures shall be incorporated to allow the roots to breathe and obtain water and nutrients. Any excavation, cutting, filing, or compaction of the existing ground surface within the protected perimeter shall be minimized. No change in existing ground level shall occur within a distance to be determined by the Arborist from the base of any protected tree at any time. No burning or use of equipment with an open flame shall occur near or within the protected perimeter of any protected tree. c. No storage or dumping of oil, gas, chemicals, or other substances that may be harmful to trees shall occur within the distance to be determined by the Arborist from the base of any protected trees, or any other location on the site from which such substances might enter the protected perimeter. No heavy construction equipment or construction materials shall be operated or stored within a distance from the base of any protected trees to be determined by the tree reviewer. Wires, ropes, or other devices shall not be attached to any protected tree, except as needed for support of the tree. No sign, other than a tag showing the botanical classification, shall be attached to any protected tree. d. Periodically during construction, the leaves of protected trees shall be thoroughly sprayed with water to prevent buildup of dust and other pollution that would inhibit leaf transpiration. e. If any damage to a protected tree should occur during or as a result of work on the site, the project applicant shall immediately notify the City Arborist of such damage. If, in the professional opinion of the Arborist, such tree cannot be preserved in a healthy state, the Arborist shall require replacement of any tree removed with another tree or trees in the same general location as the damaged tree. The number of trees adequate to compensate for the loss of the tree that is removed shall be determined by the Arborist. f. All debris created as a result of any tree removal work shall be removed by the project applicant from the property within two weeks of debris creation, and such debris shall be properly disposed of by the applicant in accordance with all applicable laws, ordinances, and regulations. g. In the event that any of the existing trees do not survive within five years after the subdivision completion and it is confirmed by a certified arborist that the trees were 10-26-09 Revised Draft Finger Avenue Conditions of Approval
