To establish the estimated reproduction of the assessed trees, I employed the standard methods found in Guide for Plant Appraisal, 9th edition (published in 2000 by the International Society of Arboriculture, Savoy IL). In addition, I 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. I used the trunk formula method to estimate the reproduction cost of each tree. This estimate is based on 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 Classification and Group Assignment lists recommended species ratings and evaluations. Condition reflects the health and structural integrity of the individual tree. The location factor considers the site, placement and contribution of the tree in its surrounding landscape. The estimated value of the nine trees recommended for preservation within the project area is $111,700 and that of the 252 trees recommended for removal is $788,300 (Table 3). In the area of the Foothill Road improvements, the estimated value of the 40 trees recommended for preservation is $236,300 and that of the 78 trees recommended for removal is $227,100.
