All tree work shall comply with the Migratory Bird Treaty Act as well as California Fish and Wildlife code 3503-3513 to not disturb nesting birds. To the extent feasible tree pruning and removal should be scheduled outside of the breeding season. Breeding bird surveys should be conducted prior to tree work. Qualified biologists should be involved in establishing work buffers for active nests. Recommendations for tree protection during construction 1. Any approved grading, construction, demolition or other work within the TREE PROTECTION ZONE should be monitored by the Consulting Arborist. 2. All contractors shall conduct operations in a manner that will prevent damage to trees to be preserved. 3. Tree protection devices are to remain until all site work has been completed within the work area. Fences or other protection devices may not be relocated or removed without permission of the Consulting Arborist. 4. Prior to grading or trenching, trees may require root pruning outside the TREE PROTECTION ZONE.Any root pruning required for construction purposes shall receive the prior approval of, and be supervised by, the Consulting Arborist. 5. Spoils from trench, footing, utility or other excavation shall not be placed within the TREE PROTECTION ZONE, neither temporarily nor permanently. 6. All grading within the dripline of trees shall be done using the smallest equipment possible. The equipment shall operate perpendicular to the tree and operate from outside the TREE PROTECTION ZONE. Any modifications must be approved and monitored by the Consulting Arborist. 7. Roots should be cut with a saw to provide a flat and smooth cut. If roots 2"and greater in diameter are encountered during site work and must be cut to complete the construction, the Consulting Arborist must be consulted to evaluate effects on the health and stability of the tree and recommend treatment. 8. 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 Consulting Arborist may require first severing the major woody root mass before extracting the trees, or grinding the stump below ground. 9. All trees shall be irrigated on a schedule to be determined by the Consulting Arborist(every 3 to 6 weeks is typical). Each irrigation shall wet the soil within the TREE PROTECTION ZONE to a depth of 30". 10.
