Silver Oaks Project <br /> Livermore, California <br /> Table 3-Suitability Factors for Tree Preservation explains the method behind the rating <br /> system. Suitability for preservation is especially valuable when used as a design <br /> component by architects and planners. This qualitative tree data is a contributing factor <br /> when deciding the cost-effectiveness and the reasonableness of whether to <br /> accommodate a tree by design. Table 4-Tree Assessment Chart contains the suitability <br /> rating for each tree with germane comments. <br /> Conclusions <br /> With the exception of trees 6 and 8, the resident trees are for the most part in fair to very <br /> good overall condition. Removal of large dead branches and judicious reduction <br /> pruning when necessary by a qualified tree contractor would be a prudent course of <br /> action prior to beginning construction activities. <br /> Trees 6 and 8 will require work to balance or reduce their foliar canopies to increase their <br /> aerodynamic properties. Proper installation of suitable hardware may increase structural <br /> integrity. Currently these two trees present a low risk of hazard to humans or domestic <br /> animals. <br /> Construction activities adjacent to the dripline of trees,grade changes or changes in the <br /> direction of run-off should be avoided. If construction impacts to trees are a concern,an <br /> effective tree protection plan that is properly implemented is expected to extend the life <br /> of these trees. <br /> Recommendations <br /> 1. Final grading,improvement and construction plans should consider the tree data <br /> presented in this report to proactively reduce construction impacts to the trees <br /> through the design process. <br /> 2. The final grading, improvement and construction plans should be reviewed by a <br /> qualified Arborist prior to the commencement of construction activities. <br /> 3. Proper implementation of an effective tree protection plan,which includes regular <br /> monitoring by a qualified Arborist,is expected to extend the life of those protected <br /> trees determined to be moderately or highly suitable for preservation. <br /> 4. All tree work (pruning and removals) is to be performed by a State of California <br /> Licensed Tree Contractor. All pruning is to be performed or directed by a Certified <br /> Arborist or a Certified Tree Worker in accordance with the Best Management <br /> Practices for Pruning (International Society of Arboriculture) and adhere to the most <br /> recent editions of the American National Standards Institute (ANSI) for Tree Care <br />
