Main Roads. o The heavy equipment operators (Operators) who maintain the roads carry out a continuous campaign of leveling and smoothing of the driving surface of the roadway using a road grader and other necessary equipment. This maintenance includes periodic replacement of the driving surface, as necessitated by erosion and wear, using earthen material trucked from identified borrow-pit areas on Observatory property. o The Operators endeavor to minimize bumps, ruts, washboard surface, and loose rock material in the roadway. o To prevent erosion and other water related damage to the roadway, periodically the drainage channels along the main road are restored and the culverts are cleared of sediment and other obstructions. This is normally performed once per year, prior to the winter rainy season. o Operations management personnel conduct a driving inspection of the main roads on a daily basis and oversee the activities of the Operators. Management communicates with the Operators regularly to establish priorities for areas of the roadway requiring attention and to convey any special requirements or instructions.
