Tree Report, Vineyard Gardens, LLC, Pleasanton, CA <br />December 10, 2007 <br />HortScience, Inc. <br />Page 8 <br />Appraisal of Value <br />The City of Pleasanton requires that the value of on-site trees be established and included as <br />part of a Tree Report. To establish these values, I employed the standard methods found in <br />Guide for Plant Appraisal, 9th edition (published in 2000 by the International Society of <br />Arboriculture, Savoy IL). In addition, I referred to Species C/ass cation and Group <br />Assignment (2004), a publication of the Western Chapter of the International Society of <br />Arboriculture. These two documents outline the methods employed in tree appraisal. <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 />Considering the four factors noted above, I established the value of the 26 on-site trees to be <br />$19,000 (Table 4). The appraised value of 4 off-site trees (Chinese hackberries #272 & 275, <br />and coast redwoods #284 ~ 285) is not required by the City. <br />Table 4. Appraisal of value: Vineyard Gardens, LLC.
