APPENDIX C <br /> ESTIMATED YARDAGE CALCULATIONS <br /> Temporary River Bed Crossing <br /> TYPICAL X-SECTION <br /> 15- <br /> 2- CULVERT <br /> - - - 4 5 - - - <br /> 27- <br /> The river bed crossing will be approximatey 80 ft long; thus, 80 ft x 94.5 <br /> ft2 = 7,560 ft3/27 = 280 Yd3 . The location of the river run borrow <br /> area is shown on Exhibit A and is 0.1 acre. The area is a gravel bar with no <br /> vegetation. <br /> Bridge (Culvert) Yardage <br /> When the 9-ft diameter culverts are removed, approximately 2,400 Yd3 of <br /> material will be excavated and taken to the subsoil stockpile for storage. <br /> After the wing walls and bidge abutements are constructed, approximately 1 ,150 <br /> Yds3 of this same material will be brought back from the subsoil stockpile <br /> and compacted in 6-in. lifts behind the abutements. The remainder of the <br /> material will remain in storage and will be used for reclamation purposes at a <br /> later date. <br /> Temporary Access Road Yardage <br /> The temporary access road will be approximately 400 feet long. The road <br /> will be constructed mainly along the side of the existing road and disturbance <br /> to the river bank area will be minimal. The yardage to be moved during the <br /> construction of >the temporary road is expected to be about 600 yds3. The <br /> bulk of this yardage will come from the side slopes of the existing access road <br /> and will be graded back into the side slopes when the bridge is completed. The <br /> temporary road is to be held into the existing road bank as close as possible <br /> and the area of the road is only 0.3 acres of which only 0.1 acre will be on <br />
