be ripped to 8 inches. Construct cut out trenches every 200 feet <br /> as per 34+050 specifications. <br /> 75+090 Remove culvert and construct low water crossing <br /> as per 23+020 specifications. <br /> 75+090 to 76+085 Grade road surface to drain to outside edge of <br /> road uniformly. Excess graded material is to be pushed against <br /> inside of cut-slope at no steeper than 3h:ly. Graded bench is to <br /> be ripped to 8 inches. Construct cut out trenches every 200 feet <br /> as per 34+050 specifications. <br /> 76+085 Construct low water crossing as per 23+020 <br /> specifications. <br /> 76+085 to 81+045 Grade road surface to drain to outside edge of <br /> road uniformly. Excess graded material is to be pushed against <br /> inside of cut-slope at no steeper than 3h:ly. Graded bench is to <br /> be ripped to 8 inches. Construct cut out trenches every 200 feet <br /> as per 34+050 specifications. <br /> 81+045 Divert stream from a point 50 feet above <br /> culvert to 50 feet below culvert using 48 inch pipe to convey flow. <br /> construct a 15 feet wide road parallel to stream upstream for 50 <br /> feet. Road will be sloped outward to shed water, and graveled with <br /> 3/4 inch rock. Build a 15 feet wide low water crossing in stream <br /> channel about 50 feet above current culvert location. Utilize <br /> nearby rock to armor crossing. Construct road segment from low <br /> water crossing to intersect pre-existing road. New road will be 15 <br /> feet wide and graveled with 3/4 inch rock. Remove culvert and <br /> associated fill. Excavate stream channel from 10 feet below low <br /> water crossing to a point 30 below existing culvert to achieve a <br /> uniform stream gradient. Channel width will match width above and <br /> below culvert location. Armor channel with riprap having a median <br /> diameter (D50) of 12 inches, obtained in area. Armor will extend <br /> the length of the excavated channel . Remove stream diversion from <br /> channel after excavation is complete. <br /> 81+045 to 85+000 Grade road surface to drain to outside edge of <br /> road uniformly. Excess graded material is to be pushed against <br /> inside of cut-slope at no steeper than 3h: 1v. Graded bench is to <br /> be ripped to 8 inches. Construct cut out trenches every 200 feet <br /> as per 34+050 specifications. <br /> 85+000 Construct low water crossing as per 23+020 <br /> specifications. <br /> 85+000 to 87+040 Grade road surface to drain to outside edge of <br /> road uniformly. Excess graded material is to be pushed against <br /> inside of cut-slope at no steeper than 3h:ly. Graded bench is to <br /> be ripped to 8 inches. Construct cut out trenches every 200 feet <br /> as per 34+050 specifications. <br /> 87+040 Construct low water crossing as per 23+020 <br />
