Preliminary Arborist Report August 18, 2016 6455 Owens Drive , Pleasanton Page 8 Trees that are recommended for preservation on site will require appropriate tree protection measures. The Tree Preservation Guidelines should be followed to ensure survival of retained trees. All of the trees recommended for preservation are located offsite. Appraisal of Value The City of Pleasanton requires the value be established of all trees to be removed. To accomplish this we used the standard methods found in Guide for Plant Appraisal, 9th edition (published in 2000 by the International Society of Arboriculture, Champaign IL). In addition, we referred to Species Classification and Group Assignment(2004), a publication of the Western Chapter of the International Society of Arboriculture. These two documents outline the methods employed in tree appraisal. The value of landscape trees is based upon four factors: size, species, condition and location. Size is measured as trunk diameter, normally 54"above grade. A multi- branched tree which has major branches below 54"above the natural grade is measured just below the first major trunk fork. The species factor considers the adaptability and appropriateness of the plant in the Bay area. The Species Classification and Group Assignment lists recommended species ratings and evaluations. Condition reflects the health and structural integrity of the individual, as noted in the Tree Assessment Form. Location considers the site, placement and contribution of the tree in its surrounding landscape. The estimated value of the 11 trees recommended for removal is$12,200. For Callery pear#112, the estimate of value is$550. Preliminary Tree Preservation Guidelines The following 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.
