<br />Tree Report, Vineyard Townhome Condominiums <br />Pleasanton. CA <br />September 15. 2005 <br /> <br />HortScience, Inc. <br />Page 9 <br /> <br />Appraisal of Value <br />The City of Pleasanton required that the value of on-site to be established and included as part <br />of a Tree Report. To establish these values, I employed the standard methods found in Guide <br />for Plant Appraisal, 9th edition (published in 2000 by the International Society of Arboriculture, <br />Savoy Il). In addition, I referred to Species Classification and Group Assignment (2004), a <br />publication of the Western Chapter of the International Society of Arboriculture. These two <br />documents outline the methods employed in tree appraisal. <br /> <br />The value of landscape trees is based upon four factors: size, species, condition and location. <br />Size is measured as trunk diameter, normally 54" above grade. The species factor considers <br />the adaptability and appropriateness of the plant in the East Bay. The Species Classification <br />and Group Assignment lists recommended species ratings and evaluations. Condition reflects <br />the health and structural integrity of the trees prior to removal. The location factor considers the <br />site. placement and contribution of the tree in its surrounding landscape. <br /> <br />Considering the four factors noted above, I established the value of the 46 on-site trees to be <br />$99,000 (Table 2). The appraised value of 12 off-site trees' is not required by the City. <br /> <br />Table 2.
