<br /> Tree Preservation Guidelines
<br /> The goal of tree preservation is not merely tree survival during construction but maintenance of
<br /> tree health and beauty for many years. Trees retained on sites that are either subject to
<br /> extensive injury during construction or are inadequately maintained become a liability rather than
<br /> an asset. The response of individual trees will depend on the amount of excavation and grading,
<br /> the care with which demolition is undertaken, and the construction methods. These impacts can
<br /> be minimized by coordinating any construction activity inside the TREE PROTECTION ZONE. Key
<br /> elements of a tree preservation plan for the tree would include:
<br /> The following recommendations will help reduce impacts to the tree from construction and
<br /> maintain and improve its health and vitality through the construction phases.
<br /> Design recommendations
<br /> 1. All plans affecting trees shall be reviewed by the Consulting Arborist with regard to tree
<br /> impacts. These include, but are not limited to, demolition plans, grading and utility plans,
<br /> landscape and irrigation plans.
<br /> 2. A TREE PROTECTION ZONE shall be established around each tree to be preserved. Since
<br /> the trees identified for preservation are well away from the proposed changes, the TREE
<br /> diameter, normally 54"above grade. A multi-branched tree, which has
<br /> major branches below 54" above the natural grade, is measured just below the first major trunk
<br /> fork. The species factor considers the adaptability and appropriateness of the plant in the Bay
<br /> area. The Species Classification and Group Assignment lists recommended species ratings and
<br /> evaluations. Condition reflects the health and structural integrity of the individual, as noted in the
<br /> Tree Assessment Form. Location considers the site, placement, and contribution of the tree in its
<br /> surrounding landscape. In this case, although the site is located in a desireable residential area of
<br /> Pleasanton, the trees are growing on an undeveloped lot,which affects the site and contribution
<br /> ratings.
