Modified Border Zone - Tiered Vegetation Management



Here is a diagram from the Sierra Club which illustrates how a tiered approach to vegetation removal in the border zones of the transmission line ROW could be achieved. This shows exclusion zones (clearance zones) based upon wire sag and wind sway and is based upon federal clearance guidelines for 200kv and 500kv lines.
