Tree Report. April 2023. HortScience | Bartlett Consulting Merritt Property. Foothill Boulevard Holding Company. Page 7 HortScience│Bartlett Consulting ● Divisions of The F.A. Bartlett Tree Expert Company  Modesto ashes #1608 and 1609 were mature trees in fair condition.  Monterey pines #1631 and 1632 were mature trees in fair condition.  Pear #916 was 9-inches and fair.  Purpleleaf plum #1716 had numerous stems that arose at ground level and was in fair condition.  Raywood ash #1721 was 20-inches and poor. It was located off-site to the south.  River red gums #1708 and 1712 were on the east side of the site near the I-680 freeway. Both were mature in development. Tree #1708 was 19-inches and in poor condition while #1712 was 28-inches and fair.  Sweetgums #1761, 1763, 1765 and 1766 were semi-mature trees near Puri Court. Condition was good. Trunk diameters ranged from 6- to 9-inches.  Western sycamores #1491 (60-inches) and 1537 (45-inches) were large mature trees on the west side of Foothill Road. Both were in fair condition. Sycamores #1758 and 1759 were semi-mature (15- and 14-inches) and in fair condition. The City of Pleasanton defines Heritage trees as having a trunk diameter of 18-inches or greater or a height of 35-feet or more. For trees with more than one stem, trunk diameter is determined by adding together the two largest stems. Using these criteria, I determined there to be 135 Heritage trees including 47 valley oaks, 33 coast live oaks, and 17 English walnuts. Description of individual trees is found on the enclosed Tree Assessment Form. Tree locations are found on the Tree Location Map. Both are included as Attachments. Suitability for Preservation Trees that are preserved on development sites must be carefully selected to make sure that they may survive development impacts, adapt to a new environment and perform well in the landscape. Our goal is to identify trees that have the potential for long-term health, structural stability and longevity. Evaluation of suitability for preservation considers several factors:  Tree health Healthy, vigorous trees are better able to tolerate impacts such as root injury, demolition of existing structures, changes in soil grade and moisture, and soil compaction than are non-vigorous trees.  Structural integrity Trees with significant amounts of wood decay and other structural defects that cannot be corrected are likely to fail. Such trees should not be preserved in areas where damage to people or property is likely.
