Preliminary Arborist Report <br />536 St. John Street, Pleasanton <br />June 20, 2016 <br />Page 7 <br />Appraisal of Value <br />The City of Pleasanton requires the value be established of all trees to be removed. To <br />accomplish this we used the standard methods found in Guide for Plant Appraisal, 9th <br />edition (published in 2000 by the International Society of Arboriculture, Champaign IL). In <br />addition, we referred to Species Classification and Group Assignment (2004), a <br />publication of the Western Chapter of the International Society of Arboriculture. These <br />two documents outline the methods employed in tree appraisal. <br />The value of landscape trees is based upon four factors: size, species, condition and <br />location. Size is measured as trunk diameter, normally 54" above grade. A multi- <br />branched tree which has major branches below 54" above the natural grade is measured <br />just below the first major trunk fork. <br />The species factor considers the adaptability and appropriateness of the plant in the Bay <br />area. The Species Classification and Group Assignment lists recommended species <br />ratings and evaluations. Condition reflects the health and structural integrity of the <br />individual, as noted in the Tree Assessment Form. Location considers the site, <br />placement and contribution of the tree in its surrounding landscape. <br />The appraised value of the 10 trees recommended for removal is $39,550. The value of <br />the four trees to be preserved is $5,350. The appraised value of each tree is provided in <br />Table 4. <br />Table 4.
