2.05.3 <br />When rock or rocky material is used for embankment, placement shall be in <br />layers not exceeding the maximum size of the rock present, and in no case shall <br />lifts exceed 30 inches in depth. Rock layers shall be compacted by routing the <br />spreading equipment and loaded hauling equipment over the entire width of the <br />fill until compaction is obtained. <br />Embankment slopes shall not be steeper than 2H:1 V, except where embankment <br />material is a minimum 85 percent rock, slopes shall not be steeper than <br />1.35HA V. Cut slopes shall not be steeper than 1.5H:1 V in unconsolidated <br />materials or 0.25H:1 V in rock. <br />Temporary erosion control measures will be implemented during the construction <br />of the haul roads. Straw bales, riprap, check dams, vegetation or other <br />alternative sedimentation control measures will be used to reduce overland flow <br />velocity, reduce run -off volume, or trap sediment. After construction is complete <br />the area disturbed will be seeded and mulched to reduce the rate and volume of <br />run -off. <br />Due to limited easement width, haul road #1 has been designed to incorporate <br />excelsior logs on the south side of the road to provide long term sediment control. <br />Drainage <br />The drainage plan for haul road #2 is shown on Map 13. The drainage plan for <br />haul road #1 is shown on Map 16. <br />Culverts are designed in accordance with the Handbook of Steel Drainage & <br />Highway Construction Products (1983). According to table HC -1, page 126, the <br />minimum depth of cover for corrugated steel pipe, H -20 live load, 2 2/3 X 1/2 inch <br />corrugations is 12- inches for diameters or spans of 12 to 96 inches. The depth of <br />cover is measured from the top of pipe to the top of subgrade. Thus, culverts will <br />be covered by compacted fill to a minimum depth of 1 foot. <br />Haul Road Surfacing <br />The haul roads will be plated with 6 inches of 1.5" road base and 12 inches of pit <br />run (minimum). The City of Fruita will require improvements be in place to <br />structurally support the amount of truck traffic proposed. <br />Haul Road Maintenance <br />The haul roads on site will be maintained in accordance with Rule 4.03.1(6). <br />Permit Application 2.05 -12 01/12 <br />
