Tree Report, 218 Ray Street, Pleasanton Ed Brennan, Consulting Arborist February 12, 2020 Page 4 Each tree was rated for suitability for preservation based upon its age, health, structural condition and ability to safely coexist within a development environment (see Tree Survey for suitability ratings for individual trees). Table 4: Tree Suitability for Preservation Good These are trees with good health and structural stability that have the potential for longevity at the site. Four trees were rated as good in suitability for preservation, two Bradford pears (trees #2 & 3), the valley oak (tree #6), and the pecan (tree #7). Moderate Trees in this category have fair health and/or structural defects that may be abated with treatment. Trees in this category require more intense management and monitoring, and may have shorter life -spans than those in the "gond" category. Three trees were rated as moderate in suitability for preservation, all Bradford pears (trees #1, 4 & 5). Poor Trees in this category are in poor health or have significant defects in structure that cannot be abated with treatment. These trees can be expected to decline regardless of management. The species or individual tree may possess either characteristics that are undesirable in landscape settings or be unsuited for use areas. No trees were included in this category. Evaluation of Impacts and Recommendations for Preservation Appropriate tree retention develops a practical match between the location and intensity of construction activities and the quality and health of trees. The Tree Survey was the reference point for tree condition and quality. Potential impacts from construction were evaluated using the Topographic Survey, Sheet 1, provided by Alexander and Associates. The Topographic Survey also shows the placement of the proposed building at the rear of the lot. My evaluation of the plan indicates that six of the seven surveyed trees could be preserved on the site. The only tree requiring removal to implement the proposed building is tree #5, a 10' diameter Bradford pear. Preservation of the other six trees is predicated on the Tree Preservation Guidelines that follow.
