Trees retained on sites that are either subject to <br /> extensive injury during construction or are inadequately maintained become a liability rat/1er <br /> than an asset. The response of individual trees will depend on the amount of excavation and <br /> I grading, the care with which demolition is undertaken, and the construction methods. <br /> Coordinating any construction activity inside the TREE PROTECTION ZONE can minimize these <br /> I impacts. <br /> I The following recommendations will help reduce impacts to trees from development and <br /> maintain and improve their health and vitality through the clearing, grading and construction <br /> phases. <br /> I Design recommendations <br /> 1. The Consulting Arborist shall review all project plans to assess potential impacts to <br /> trees. <br /> I 2. A TREE PROTECTION ZONE shall be established around each tree to be preserveq. <br /> The TPZ is shown on the Tree Survey Map. No grading, excavation, constructipn or <br /> I storage of materials shall occur within that zone. <br /> 3. No underground services including utilities, sub-drains, water or sewer shall be placed <br /> in the TREE PROTECTION ZONE. <br /> I <br /> I <br /> I 4. Tree Preservation Notes, prepared by the Consulting Arborist, should be included <br /> on all plans. <br /> 5. Any herbicides placed under paving materials must be safe for use around trees and <br /> labeled for that use. <br /> 6. Irrigation systems must be designed so that no trenching will occur within the TREE <br /> PROTECTION ZONE. <br />
