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