Attachment B <br />Healthy trees that have a reasonable chance of survival considering the <br />base zone or special area zone designation and other applicable approval <br />criteria; <br />Trees located within vegetated corridors and stands rather than individual <br />isolated trees subject to windthrow; <br />Trees that fulfill a screening function, provide relief from glare, or shade <br />expansive areas of pavement; <br />4. Trees that provide a buffer between potentially incompatible land uses; <br />5. Trees located along the perimeter of the lot(s) and within building setback <br />areas; <br />6. Trees and stands of trees located along ridgelines and within view <br />corridors; <br />7. Trees with significant habitat value; <br />S. Trees adjacent to public parks, open space and streets; <br />9. Trees located along a water feature; <br />10. Heritage trees. <br />Staff Findings <br />The applicant states that there are approximately 135 existing trees on the subject property (see <br />page 28 of the applicant's June 14, 2013 written statement). The applicant's tree removal and <br />preservation plan is shown on sheet L3 (Attachment D-4). The applicant states that only four <br />"significant" trees will be removed, according to the following definition: <br />EC 9.0500 Significant Tree: A living, standing tree having a trunk with a minimum <br />cumulative diameter breast height of 8 inches, or, when there are multiple <br />trunks, having a minimum cumulative diameter breast height of 8 inches, <br />considering the 2 largest trunks measured at 4.5 feet above mean ground level at <br />the base of the trunk or trunks. <br />The location, species, and size of the trees on the subject property are also shown in the applicant's <br />topographical survey, which confirms that most of the trees are fruit and filbert trees that are less <br />than eight-inches in diameter. Most of those trees are proposed for removal. The larger fruit trees <br />along the southeast property line are proposed for preservation, which complies with the above <br />approval criterion as these trees provide screening and buffering functions. The applicant also <br />proposes to preserve a group of ash trees, west of Building 7, and a cluster of young cedar trees <br />between Buildings 3 and 4. Preservation of these trees complies with the above criterion because <br />they are stands of trees, rather than isolated individuals. The most significant tree being preserved <br />on the subject property is a 14-inch fir located in the southwest portion of the property. The <br />applicant's plans delineate the critical root zone (CRZ) of the tree to show that it can survive <br />construction impacts, which are primarily the surrounding vehicle use areas, rather than buildings. <br />The applicant's plans also show the CRZ of three fir trees on the adjacent property to the west to <br />show that the proposed parking garages and concrete wall will not require their removal.
