Suitability for Preservation Before evaluating the impacts that will occur during development, it is important to consider the quality of the tree resource itself, and the potential for individual trees to function well over an extended length of time. Trees that are preserved on development sites must be carefully selected to provide greater assurance they survive development . : impacts, adapt to a new environment, and perform !r> • 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. For instance, tree#106 was all but dead and should be removed regardless of construction plans. • 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. • Species response There is a wide variation in the response of individual species to construction impacts and changes in the environment. Neither species evaluated is tolerant of construction impacts and site changes or disturbances. • Tree age and longevity Old trees, while having significant emotional and aesthetic appeal, have limited physiological capacity to adjust to an altered environment. Young trees are better able to generate new tissue and respond to change. Italian cypress trees (#104 and 105)were good young trees that have good longevity. • Invasiveness Species that spread across a site and displace desired vegetation are not always appropriate for retention. This is particularly true when indigenous species are displaced. The California Invasive Plant Inventory Database (http://www.cal- ipc.orq/paf/)lists species identified as being invasive. Pleasanton is part of the Central West Floristic Province. Neither of the species found at the site are listed as invasive. ion of the tree species, and its potential to remain an asset to the site. 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. e shocked if any one of us didn't get nasty grams from then on and I agree with Commissioner O'Connor that that intersection is already horrible. So you may be talking two more cars to 13 and you're on Owens, and if you block Hopyard we're going to be hearing it forever and I would hate to vote in favor of a project that would do that. Again, my comment about the plans labeled "Owens Court." Starbucks has a base for your evaluation as Bernal. I do worry that that is not comparable for the traffic and my only comment to that is I avoid that Starbucks because of its location and its circulation pattern. So I'm not being counted in there because it's so deep and so tricky to get through that parking lot to get to that Starbucks buried in there that I think we're misrepresenting what we might see here with the prominent freeway access and the volume of traffic going down Hopyard.
