The site of any surface mining operation shall be surveyed by a registered civil engineer or licensed surveyor and shall be defined by a series of poles. The poles shall consist of two and one-half inch pipe and shall be six feet in height measured from the ground level and painted a bright color. The poles shall be installed and maintained at each change of direction along the entire length of the site in such a manner that an individual standing at one such pole can clearly see the next pole in either direction. For good cause shown, the Planning Director may waive or modify this requirement for any mining operations that are proposed to result in finished elevations that are not below the natural ground elevations at the perimeter of the site or for any extraction operations proposed to be located more than 1,000 feet from any property lines.
