Tree Report, Trinity Lutheran Church HortScience, Inc. WMB Architects, June 2006 Page 8 Appraisal of Value The City of Pleasanton requires that The value of all trees be established for bonding and replacement calculation purposes. To accomplish this, I 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, 1 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. The species factor considers the adaptability and appropriateness of the plant in the East Bay area. The Species Class cation and Group Assignment lists recommended species ratings and evaluations. Condition reflects the health and structural integrity of the individual, as noted in the Tree Survey Form. Location considers the site, placement and contribution of the tree in its surrounding landscape. The appraised value of the 33 surveyed trees is $58, 950 The appraised value of the 11 trees recommended for preservation is $27,800 (Table 4). This includes the values of the two (2) street trees (#428 and 440), and the two (2) off-site trees (#457 and 458). The appraised value of the 22 trees recommended for removal is $31,150 (Table 5, following page).
