| Calculations Planting Area Diameter at Breast Height (DBH)= standard measure of tree size by trunk diameter at four and a half (4.5) feet above ground level.
Total DBH is the sum of each trees DBH on-site.
Percentage of DBH Retained= DBH Post-construction/ DBH Pre-construction
TPA is measured from the trunk location to a perfect radius distance ten (10) feet beyond the furthest drip line of the individual tree, or it is measured as one (1) foot of linear distance away from the trunk for each caliper inch of tree at breast height. During construction, all reasonable steps necessary to prevent the destruction or damaging of critical root zones shall be taken. No excess soil, additional fill, equipment, liquids, or construction debris shall be placed within the drip line of any protected tree or tree grove. Protective barriers constructed of wood or chain linked fence shall be installed for the duration of the construction process phase. |
