Protective barricades shall be placed around all protected trees designated to be saved, prior to the start of development activities or grading. These barricades shall consist of two inches by four inches posts with one inch by four inch rails or orange safety fence. Protective barricades shall remain in place until development activities are complete. The area within the protective barricade shall remain free of all building materials, stockpiled soil, or other construction debris. Construction traffic, storage of vehicles and materials, and grading shall not take place within the protective areas of the existing trees. Barricades shall be erected at a recommended minimum distance from the base of protected trees according to the following standards.
10.4.1 For trees ten inches or less diameter at breast height (DBH), protective barricades shall be placed a minimum distance of ten feet from the base of each protected tree, or outside the dripline, whichever is greater.
10.4.2 For trees greater than ten inches DBH, protective barricades shall be placed at a minimum distance equal to ten feet from the base of a protected tree plus an additional one foot for each additional one inch DBH greater than ten inches DBH, or outside the dripline, whichever is greater.
Construction access to a site should occur where an existing or proposed entrance/exit is located. Except for driveway access points, sidewalks, curbs, and gutters, land disturbance within a tree dripline is strongly discouraged. Where grading within a tree dripline cannot be avoided, cut and fill shall be limited to one-fourth to one-third of the area within the dripline, tree roots must be pruned with clean cuts at the edge of the disturbed area, and no fill shall be placed within the dripline of a tree without venting to allow air and water to reach the roots. Trees and undergrowth in designated open space in an approved plan shall remain undisturbed, except for permitted pathways.
