As trees age, the likelihood of <br /> branches or entire trees failing will increase. Therefore, annual inspection for hazard potential is <br /> recommended. <br /> If you have any questions regarding my observations or recommendations, please contact me. <br /> HortScience, Inc. <br /> 25<-17 <br /> Maryellen Bell <br /> Horticultural Consultant WE#5643A <br />, 2002)and adhere to the most recent editions of <br /> the American National Standard for Tree Care Operations(Z133.1)and Pruning (A300). <br /> While in the tree, the Certified Arborist should perform an aerial inspection to identify <br /> defects that are not visible from the ground that require treatment. <br /> 4. All tree work shall comply with the Migratory Bird Treaty Act as well as California Fish <br /> and Wildlife code 3503-3513 to not disturb nesting birds. To the extent feasible tree and <br /> pruning and removal should be scheduled outside of the breeding season. Breeding bird <br /> surveys should be conducted prior to tree work. Qualified biologists should be involved in <br /> establishing work buffers for active nests. <br /> 5. Apply and maintain a 4-6"-deep layer of wood chip mulch (gorilla hair mulch is not <br /> acceptable)within the TREE PROTECTION ZONE. Keep mulch 24-30"from the trunk. Allow <br /> leaf litter to accumulate under the tree. <br /> Recommendations for tree protection during construction <br /> 1. No demolition, excavation, construction or storage of materials shall occur within the <br /> TREE PROTECTION ZONE unless approved and monitored by the Consulting Arborist. No <br /> underground services including utilities, sub-drains, water, sewer or irrigation shall be <br /> placed in the TREE PROTECTION ZONE unless approved and monitored by the Consulting <br /> Arborist. Spoil from trench, footing, utility or other excavation shall not be placed within <br /> the TREE PROTECTION ZONE, either temporarily or permanently. Any modifications must <br /> be approved and monitored by the Consulting Arborist. <br /> 2. All demolition, excavation and construction within the dripline of trees shall be done using <br /> the smallest equipment possible. The Consulting Arborist will identify where hand <br /> excavation may be required. Motorized equipment shall not be used within the TREE <br /> PROTECTION ZONE. <br /> 3. Prior to excavation for the demolition and construction the tree may require root pruning <br /> outside the TREE PROTECTION ZONE by cutting all roots cleanly to the depth of <br /> construction. Roots will be exposed by either: pulling soil away from the tree by digging <br />, normally 54"above grade. A multi-branched tree, which has <br />
