planting screen. <br /> 8. If any significant tree in development or building site <br /> is cut, damaged or the area within the tree's dripline has <br /> been encroached upon by grading equipment without City <br /> authorization, the City may require planting of two new <br /> trees. In addition, if the City determines that a damaged <br /> tree will probably not survive, it shall be removed by the <br /> developer. <br /> a. Any trees required to be planted shall be varied in <br /> species, shall maximize the use of species native to the <br /> area, shall not include any species under disease epidemic <br /> and shall be hardy under local conditions. Trees shall be at <br /> least 2 1/2 inches in diameter for deciduous trees and eight <br /> feet tall for coniferous trees. <br /> b. Any trees required to be planted shall be replaced if <br /> they die or appear to be dying within one year of planting by <br /> the person responsible for the planting. t <br /> C. Before any construction or grading takes place, <br /> snow fencing or erosion control fencing shall be placed <br /> around the borders of woodlots or the driplines of large <br /> trees to be preserved. Signs shall be placed along this <br /> fence line prohibiting grading beyond the fence line. <br /> SECTION V TREE AND SITE RELATED DISTURBANCES <br /> ,-, A. Tree protection zones, specimen trees or stands of trees <br /> designated to be saved must be protected from the following <br /> damages which may occur during all phases of land disturbance <br /> and construction processes. Methods of tree protection and <br /> disturbance prevention are provided in Section VI. <br /> 1. Direct physical root damage. <br /> 2 . Indirect root damage. <br /> 3 . Trunk and crown disturbances. <br /> B. Direct physical root damage most frequently occurs during <br /> site clearing and grading operations, where transport or <br /> feeder roots are cut, torn, or removed. <br /> 1. Transport and feeder roots tend to tangle and fuse <br /> among the roots of adjacent trees. The removal of trees with <br /> heavy machinery along the outer periphery of a tree save area <br /> can result in considerable damage within the tree save area. <br /> 2 . The most substantial form of root damage for all <br /> root types occurs in the form of cut roots. Roots are cut in <br /> grade reduction, or from trenching for underground utilities, <br /> sanitary sewer, or storm sewer lines. <br /> 3 . A more subtle form of root damage is the loss of <br /> feeder roots. Feeder roots normally occur within the organic <br /> layer, and the surface four inches of top soil, subsequently, <br /> these roots can be easily damaged by the track action from a <br /> single bulldozer pass. The stripping of top soil within a <br /> tree's critical root zone can totally eliminate its feeder <br /> root system. <br /> C. Indirect root damage through site modification can result <br /> from positive grade changes, temporary storage of fill <br /> material, the sedimentation of erosion materials, soil <br />
