Trees retained on sites that are either subject to extensive injury during construction or are inadequately maintained become a liability rather than an asset. The response of individual trees depends on the amount of excavation and grading. care with which demolition is undertaken, and construction methods. Coordinating any construction activity inside the TREE PROTECTION ZONE can minimize these impacts. 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. Design recommendations 1. Any changes to the plans affecting the trees should be reviewed by the consulting arborist with regard to tree impacts. These include, but are not limited to. site plans, improvement plans, utility and drainage plans. grading plans, landscape and irrigation plans, and demolition. Trunk locations, trunk elevations and driplines should be included on all plans. 2. TREE PROTECTION ZONE shall be established around each tree. No grading, scarification, compaction, excavation, construction or storage of materials shall occur within that zone. No underground services including utilities, sub-drains, water or sewer shall be placed in the TREE PROTECTION ZONE. Spoil from trench, footing, utility or other excavation shall not be placed within the TREE PROTECTION ZONE, either temporarily nor permanently. The limits of the Tree Protection Zone will be adjusted following design changes. The TREE PROTECTION ZONE for trees shall be defined as follows (see following page).
