<br /> Tree Appraisals
<br /> The City of Pleasanton requires that the value of trees growing on development sites be
<br /> determined. The trees were appraised using the trunk formula method found in the
<br /> Guide for Plant Appraisal 9th edition,(Champaign IL.:200C, International Society of
<br /> Arboriculture). A regional companion publication, Species Classification and Group
<br /> Assignment (2004, Western Chapter-International Society of Arboriculture), was also
<br /> used. The value of landscape trees and plants is based upon four factors: size, species,
<br /> condition, and location. Size is measured as trunk diameter, at 54" above grade. The
<br /> species factor consider: the adaptability and appropriateness of the plant in the region.
<br /> Condition reflects the health and structural integrity of the individual tree. The location
<br /> factor considers the site, placement, and contribution of the tree in the surrounding
<br /> landscape.
<br /> Applying the above-described method to the 22 trees growing on the site yielded an
<br /> aggregate total value of$ $67,850.00. Values for individual trees are shown in Tables 4 and
<br /> 5.
