09/10/2012 Impact: Impact BIO—4: Project grading and other construction activity has the potential to disturb trees intended to remain. Mitigation: MM BIO-4: The applicant shall fund the preparation and implementation of a Tree Protection Plan prepared by a certified arborist to ensure protection of trees to remain. The Tree Protection Plan shall include the following protection measures: 1. Before start of any clearing, excavation, construction or other work on the site, every protected tree("protected"means designed 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. 2. 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,filling, or compaction of the existing ground surface within the protected perimeter shall be minimized. No change in existing gound 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. 3. 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 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. 4. 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. 5. 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 4 RESO.#15217 MUFF#613
