4. Establish a Tree Protection Zone around each tree to be preserved. For design purposes, the Tree Protection Zone shall be the edge of grading. No grading, excavation, construction or storage of materials shall occur within that Zone. 5. Install protection around all trees to be preserved, to be located three feet outside the limit of grading. No entry is permitted into a Tree Protection Zone without permission of the project superintendant. 6. Route underground services including utilities, sub-drains, water or sewer around the Tree Protection Zone. Where encroachment cannot be voided, special construction techniques such as hand digging or tunneling under roots shall be employed where necessary to minimize root injury. 7. Use only herbicides safe for use around trees and labeled for that use, even below pavement. 8. Design irrigation systems so that no trenching shall occur within the Tree Protection Zone. Pre-Construction and Demolition Treatments and Recommendations 1. The demolition contractor shall meet with the Consulting Arborist before beginning work to discuss work procedures and tree protection. 2. Trees to be removed shall be felled so as to fall away from Tree Protection Zone and avoid pulling and breaking of roots of trees to remain. If roots are entwined, the consultant may require first severing the major woody root mass before extracting the trees, or grinding the stump below ground. Tree Protection During Construction 1. Prior to beginning work, the contractors working in the vicinity of trees to be preserved are required to meet with the Consulting Arborist at the site to review all work procedures, access routes, storage areas and tree protection measures. 2. Any grading, construction, demolition or other work that is expected to encounter tree roots should be monitored by the Consulting Arborist. 3. If injury should occur to any tree during construction, it should be evaluated as soon as possible by the Consulting Arborist so that appropriate treatments can be applied. 4. Fences shall be erected to protect trees to be preserved. Fences are to remain until all site work has been completed. Fences may not be relocated or removed without , permission of the project superintendent. 5. Construction trailers, traffic and storage areas must remain outside fenced areas at all times. 6. No materials, equipment, spoil, waste or wash-out water may be deposited, stored, or parked within the Tree Protection Zone (fenced areas). 7. Any additional tree pruning needed for clearance during construction must be performed by a qualified arborist and not by construction personnel. 8. All trees shall be irrigated on a schedule to be determined by the Consulting Arborist. Each irrigation shall wet the soil within the Tree Protection Zone to a depth of 30 inches. 9. Any roots damaged during grading or construction shall be exposed to sound tissue and cut cleanly with a saw. LUND RANCH II(PUD-25)RESIDENTIAL PROJECT 6 FINDINGS
