Arborist Report—Gudaitis Residence, Pleasanton Page 10 January 19, 2021 Pre-demolition and pre-construction treatments and recommendations 1. The demolition and construction superintendents shall meet with the Consulting Arborist before beginning work to review all work procedures, access routes, storage areas, and tree protection measures. 2. Fence all trees to be retained to completely enclose the TREE PROTECTION ZONE prior to demolition, grubbing or grading. Fences shall be 6 ft. chain link or equivalent as approved by the City. 3. Apply and maintain 4-6"wood chip mulch within the TREE PROTECTION ZONE. Keep the mulch 2'from the base of tree trunks. 4. Branches extending into the work area that can remain following demolition shall be tied back and protected from damage. 5. Fences are to remain until all grading and construction is completed. Where demolition must occur close to trees, such as removing curb and pavement, install trunk protection devices such as winding silt sock wattling around trunks or stacking hay bales around tree trunks. 6. Prune trees to be preserved to clean the crown of dead branches 1" and larger in diameter, raise canopies as needed for construction activities. a. All pruning shall be done by a State of California Licensed Tree Contractor(C61/D49). All pruning shall be done by Certified Arborist or Certified Tree Worker in accordance with the Best Management Practices for Pruning (International Society of Arboriculture, 2002) and adhere to the most recent editions of the American National Standard for Tree Care Operations (Z133.1)and Pruning (A300). b. The Consulting Arborist will provide pruning specifications prior to site demolition. c. Branches extending into the work area that can remain following demolition shall be tied back and protected from damage. d. While in the tree the arborist shall perform an aerial inspection to identify any defects, weak branch and trunk attachments and decay not visible from the ground. Any additional work needed to mitigate defects shall be reported to the property owner. 7. Tree(s)to be removed that have branches extending into the canopy of tree(s)or located within the TREE PROTECTION ZONE of tree(s)to remain shall be removed by a Certified Arborist or Certified Tree Worker and not by the demolition contractor. The Certified Arborist or Certified Tree Worker shall remove the trees in a manner that causes no damage to the tree(s)and understory to remain. Stumps shall be ground below grade. 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 down brush and trees shall be removed from the TREE PROTECTION ZONE either by hand, or with equipment sitting outside the TREE PROTECTION ZONE. Extraction shall occur by lifting the material out, not by skidding across the ground. Brush shall be chipped and spread beneath the trees within the TREE PROTECTION ZONE 10. Structures and underground features to be removed within the TREE PROTECTION ZONE shall use equipment that will minimize damage to trees above and below ground, and operate from outside the TREE PROTECTION ZONE. Tie back branches and wrap trunks with protective materials to protect from injury as directed by the Project arborist. The Project arborist shall be on-site during all operations within the TREE PROTECTION ZONE to monitor demolition activity. ,,t1:,. -4, ' '?r!'• '. .#e di •uj' 1; 0:11 11 tr... za. cli• ,.,... . 126* e:t4,104.,- z FM ,::2.510 6.K.44ve ..r• „n•et.' .r---3 7- A.
