9.12) Material larger than three (3) inches shall be considered oversized and shall be removed from the <br />road surface so that there will be no berm or ridge on the completed road surface. All berms, either new <br />or existing, shall be removed from shoulders to the maximum extent possible. Only short lengths of <br />berms will be permitted to remain on roadways i.e., not to exceed 12 feet where protruding stumps at <br />the road shoulder or culvert end sections prohibit removal. <br />9.13) No oversized material, which protrudes above roadway elevation, shall be left on the shoulder or <br />edge of the roadway. <br />9.14) The roads being used by the holder will be graded, using a road grader, a minimum of two (2) <br />times per year, spring and fall, in addition to any maintenance performed by the county road crew. The <br />first pass by the grader will start at the outside shoulder toward the ditch line. On rutted roads, a <br />preliminary pass will be needed down the middle of the road to cut ruts prior to making usual passes. <br />9.15) It is recommended that one laborer work with each grader used on road maintenance. The laborer <br />should work directly behind each grader with the responsibility to remove rocks from the ditches, <br />remove any rocks over three (3) inches remaining on the roadway, fill holes made when rocks are <br />removed, and remove fallen trees so they are outside the clearing limits. <br />9.16) Existing lead -in ditches and catch basins on all culverts shall be cleared of all material to provide an <br />open water flow. The discharge end of the culverts shall be cleared of material to effectively disperse <br />the flow of water. <br />9.17) Road maintenance will not generally be permitted to exceed one (1) mile intervals at one time. <br />Berms of material caused by road maintenance operations will be removed from the roadway prior to <br />the end of each day's work and not left in place over night, over weekends, or holidays unless <br />unfavorable weather or breakdowns prevent removal (see signing). <br />9.18) Maintenance of back slopes will not normally be required unless sloughing or caving has occurred. <br />The back slope shall not be undercut when pulling the ditches. <br />9.19) The area immediately before and after cattle guards shall be bladed in such a manner as to effect <br />smooth transition when passing from roadway over cattle guard and back to roadway. Back drag excess <br />material and grade away from cattle guards to fill voids and ensure cattle guards are not filled with <br />material from road surface. Surface material that is deposited in cattle guards by maintenance <br />operations must be removed and mixed back into the roadway. <br />9.20) The pulling of ditches shall be included with blading procedures. Widened roadway sections at <br />cattle guards, curves, fills, and turnouts shall also be included with the blading of the roadway. The <br />shoulder line shall be definite, continuous, and smooth with no abrupt changes in alignment. <br />9.21) Waste material from the road such as from slides or sloughs shall not be deposited in streams, <br />stream channels, or at locations which could cause damage through silting or obstructing of streams or <br />reservoirs. <br />Page 3 of 4 <br />
