Updated Arborist Report 3987 Stanley Pleasanton, CA Introduction and Overview You are planning to construct multiple housing units on the property you recently purchased. The large lot had a house, detached garage, two out buildings and was moderately forested. The City of Pleasanton requires that an Arborist Report be prepared as part of project submittals. This report provides the following information: 1. An evaluation of the health and structural condition of the trees within the proposed project area based on a visual inspection from the ground. 2. An assessment of the impacts of constructing the proposed project on the trees. 3. An appraisal value of the trees according to the procedures described in the Guide for Plant Appraisal(Council of Tree and Landscape Appraisers). 4. Guidelines for tree preservation prior to and during the demolition and construction phases of development. Tree Assessment Methods Trees were assessed on December 8, 2016. The survey included trees 6" in diameter and greater, located on the property and adjacent to property lines. The assessment procedure consisted of the following steps: 1. Identifying the tree as to species; 2. Tagging each tree with an identifying number and recording its location on a map; 3. Measuring the trunk diameter at a point 4.5' 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, and its potential to remain an asset to the site for years to come. 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. s, and materials? Conclusion Discussion Point#3 3.
