Arborist Report
<br /> Gudaitis Residence
<br /> Pleasanton, CA
<br /> Introduction and Overview
<br /> Ms. Donna Gudaitis is planning to redevelop the subject property located at 375 Sycamore Road
<br /> in Pleasanton, CA. The proposed project area currently contains a single-family home and rear
<br /> yard. HortScience I Bartlett Consulting (Divisions of The F.A. Bartlett Tree Expert Company)was
<br /> asked to prepare an Arborist Report as a part of the application to the City of Pleasanton.
<br /> This report provides the following information:
<br /> 1. Assessment of the health and structural condition of the trees within the proposed project
<br /> area based on a visual inspection from the ground.
<br /> 2. Evaluation of the impacts to trees based on development plans provided by Alexander&
<br /> Associates (8/26/20)
<br /> 3. Estimated value of trees based on the Council of Tree and Landscape Appraisers
<br /> methodology.
<br /> 4. Guidelines for tree preservation during the design, construction and maintenance phases
<br /> of development.
<br /> Tree Assessment Methods
<br /> Trees were assessed on December 2 and 16, 2020 and January 15, 2021. The assessment
<br /> included all trees within or adjacent to the project boundary with a diameter of 6"or greater.Tree
<br /> tag numbers started at#50. The assessment procedure consisted of the following steps:
<br /> 1. Identifying the tree species;
<br /> 2. Tagging each tree with an identifying number and recording its location on a map;
<br /> 3. Measuring the trunk diameter at a point 54" above grade; for off-site trees diameters
<br /> were estimated.
<br /> 4. Evaluating the health and structural condition using a scale of 1 —5 based on a visual
<br /> inspection from the ground:
<br /> 5-A healthy, vigorous tree, reasonably free of signs and symptom of disease,with
<br /> good structure and form typical of the species.
<br /> 4-Tree with slight decline in vigor, small amount of twig dieback, minor structural
<br /> defects that could be corrected.
<br /> 3-Tree with moderate vigor, moderate twig and small branch dieback, thinning of
<br /> crown, poor leaf color, moderate structural defects that might be mitigated with
<br /> regular care.
<br /> 2-Tree in decline, epicormic growth, extensive dieback of medium to large branches,
<br /> significant structural defects that cannot be abated.
<br /> 1 -Tree in severe decline, dieback of scaffold branches and/or trunk; most of foliage
<br /> from epicormics; extensive structural defects that cannot be abated.
<br /> 5. Rating the suitability for preservation as "high", "moderate" or"low". Suitability for
<br /> preservation considers the health, age and structural condition of the tree, and its
<br /> potential to remain an asset to the site for years to come.
<br /> High: Trees with good health and structural stability that have the potential
<br /> for longevity at the site.
<br /> Moderate: Trees with somewhat declining health and/or structural defects that
<br /> can be abated with treatment. The tree will require more intense
