Where extensive clearing or pruning appears to be necessary for a proposed new line the feasibility of relocating the line should be investigated by the District Engineer. Reasonable hand trenching may be required for underground lines in order to minimize clearing and pruning or for construction of the line at locations not accessible to machinery in order to avoid excessive clearing and pruning. In some cases, directional boring may be required to minimize clearing in dense wooded areas and heavily erodible soils in lieu of open trench methods.
