Tree Preservation Notes, prepared by the Consulting Arborist, should be included on all plans. 6. Any herbicides placed under paving materials must be safe for use around trees and labeled for that use. 7. Irrigation systems must be designed so that no trenching will occur within the TREE PROTECTION ZONE. 8. As trees withdraw water from the soil, expansive soils may shrink within the root area. Therefore, foundations, footings and pavements on expansive soils near trees should be designed to withstand differential displacement. Pre-construction treatments and recommendations 1. The construction superintendent shall meet with the Consulting Arborist before beginning work to discuss work procedures and tree protection. 2. Fence trees to be retained to completely enclose the TREE PROrEC71oN ZONE prior to demolition, grubbing or grading. Fences shall be 6 ft. chain link or equivalent as approved by the City. Fences are to remain until all grading and construction is completed. 3. Prune trees to be preserved to clean the crown and to provide clearance. If pruning of off-site trees #457 and 458 is required, we recommend it be done with the property owner's prior knowledge. All pruning shall be done by a State of California Licensed Tree Contractor (C61/D49). All pruning shall be done by Certified Arborist or Certified Tree Worker in accordance with the Best Management Practices for Pruning (International Society of Arboriculture, 2002) and adhere to the most recent editions of the American National Standard for Tree Care Operations (2133.1) and Pruning (A300).
