Updated Arborist Report 4112 Foothill Road Pleasanton, CA Introduction and Overview lshaq and Sina Osman are planning to develop the site at 4112 Foothill Road in Pleasanton, CA. Current site use consists of a gently sloped, open field surrounded by an oak woodland. HortScience, Inc.was asked to prepare an Arborist Report for the site as part of the development application to the City of Pleasanton. This report provides the following information: 1. An evaluation of the health and structural condition of the trees and area surrounding the building pad based on a visual inspection from the ground. 2. An assessment of the development impacts to the trees based on the drawings provided by the client. 3. An appraisal of value for the trees to be removed according to the procedures described in the Guide for Plant Appraisal(Council of Tree and Landscape Appraisers). 4. Guidelines for tree preservation during the design, construction and maintenance phases of development. Assessment Methods Trees were assessed on October 5, 2017. The assessment included all trees within and adjacent to the proposed construction areas measuring 6"and greater in diameter. The assessment procedure consisted of the following steps: 1. Identifying the species of tree; 2. Tagging each tree with a numerically coded metal tag and recording its location on a map; 3. Measuring the trunk diameter at a point 54"above grade; 4. Evaluating the health and structural condition using a scale of 1 —5: 5-A healthy, vigorous tree, reasonably free of signs and symptoms of disease, with good structure and form typical of the species. 4-Tree with slight decline in vigor, small amount of twig dieback, minor structural defects that could be corrected. 3-Tree with moderate vigor, moderate twig and small branch dieback, thinning of crown, poor leaf color, moderate structural defects that might be mitigated with regular care. 2-Tree in decline, epicormic growth, extensive dieback of medium to large branches, significant structural defects that cannot be abated. 1-Tree in severe decline, dieback of scaffold branches and/or trunk; most of foliage from epicormics; extensive structural defects that cannot be abated. 5. Rating the suitability for preservation as"high", "moderate"or"low". Suitability for preservation considers the health, age and structural condition of the tree species, and its potential to remain an asset to the site. High: Trees with good health and structural stability that have the potential for longevity at the site. Moderate: Trees with somewhat declining health and/or structural defects than can be abated with treatment. The tree will require more intense management and monitoring, and may have shorter life span than those in 'high' category. Low: Trees in poor health or with significant structural defects that cannot be mitigated. Tree is expected to continue to decline, regardless of treatment. The species or individual tree may have characteristics that are undesirable for landscapes, and generally are unsuited for use areas. (i.e. root pruning, trimming, setting up tree protection, etc.). The bond or security may be released early with a certification letter by the arborist confirming he/she was present during said tree work and work was performed in accordance with the arborist's recommendations.
