Land leveling costs for <br /> <br /> <br />gravity irrigated fields were not included in the Task Bon-farm <br /> <br /> <br />costs. The Task B report, however, estimated land leveling <br /> <br /> <br />quantities in the range of one foot average cuts at a cost of $0.50 to <br /> <br /> <br />$1.00 per cubic yard. As a conservatively low estimate, an average <br /> <br /> <br />6-inch cut at $0.50 per cubic yard for a total cost of $403 per acre <br /> <br /> <br />was assumed for this Task D analysis. Amortizing this cost at 8-3/8 <br /> <br /> <br />percent interest over 50 years gives a cost of $34.40, or in round <br /> <br /> <br />numbers, $35 per acre. This cost was then included in the on-farm <br /> <br /> <br />costs for gravity irrigation. <br /> <br />D.3 OFF-FARM IRRIGATION TRANSMISSION SYSTEM COST <br /> <br /> <br />D.3.1 General <br /> <br /> <br />The off-farm irrigation transmission facilities will generally <br /> <br /> <br />consist of transmission pipelines, pumping stations, and diversion <br /> <br /> <br />facilities. Roads for access to pump stations; rights-of-way; and <br /> <br /> <br />the extension of electrical power services to pumping stations were <br /> <br /> <br />not included in the cost analysis. Costs for those items included <br /> <br /> <br />are based on experience with similar facilities. All costs are then <br /> <br /> <br />amortized using a discount rate of 8-3/8 percent over a 50 year <br /> <br /> <br />proj ect 1 ife. <br /> <br />4 <br />
