Preliminary Arborist Report August 18, 2016 6455 Owens Drive , Pleasanton Page 9 7. Ensure adequate but not excessive water is supplied to trees; in most cases occasional irrigation will be required. Avoid directing runoff toward trees. Pre-construction treatments and recommendations 1. All tree work shall comply with the Migratory Bird Treaty Act as well as California Fish and Wildlife code 3503 &3503.5 to not disturb nesting birds. Tree pruning and removal should be scheduled outside of the breeding season to avoid scheduling delays. 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. All contractors shall conduct operations in a manner that will prevent damage to the off-site tree to be preserved. 2. Any grading, construction, demolition or other work that is expected to encounter tree roots should be monitored by the Consulting Arborist. 3. Any root pruning required for construction purposes shall receive the prior approval of and be supervised by the Consulting Arborist. 4. If injury should occur to any tree during construction, it should be evaluated as soon as pos 5. sible by the Consulting Arborist so that appropriate treatments can be applied. 6. Any additional tree pruning needed for clearance during construction must be performed by a Certified Arborist and not by construction personnel. If you have any questions about my observations or recommendations, please contact me. HortScience, Inc. Darya Barar Certified Arborist WE-6757A ing 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. Project plans affecting the trees shall be reviewed by the Consulting Arborist with regard to tree impacts. These include, but are not limited to, demolition plans, site plans, improvement plans, utility and drainage plans, grading plans and landscape and irrigation plans. Establish the Tree Protection Zone at the project perimeter. The project's security fence shall serve as protective fencing for off-site Callery pear#112. 2. Irrigation systems must be designed so that no trenching severs roots larger than 1" in diameter will occur within the TREE PROTECTION ZONE. 3. Tree Preservation Guidelines prepared by the Consulting Arborist, which include specifications for tree protection during demolition and construction, should be included on all plans. 4. Any herbicides placed under paving materials must be safe for use around trees and labeled for that use. 5. Do not lime the subsoil within 50' of any tree. Lime is toxic to tree roots. 6. As trees withdraw water from the soil, expansive soils may shrink within the root area. Therefore, foundations,footings and pavements on expansive soils near trees should be designed to withstand differential displacement. hat intersection is already horrible. So you may be talking two more cars to 13 and you're on Owens, and if you block Hopyard we're going to be hearing it forever and I would hate to vote in favor of a project that would do that. Again, my comment about the plans labeled "Owens Court." Starbucks has a base for your evaluation as Bernal. I do worry that that is not comparable for the traffic and my only comment to that is I avoid that Starbucks because of its location and its circulation pattern. So I'm not being counted in there because it's so deep and so tricky to get through that parking lot to get to that Starbucks buried in there that I think we're misrepresenting what we might see here with the prominent freeway access and the volume of traffic going down Hopyard.
