t)7r '" ;;.. vb Plan of Development Three dikes would be required across low areas to maintain a minimum crest elevation of 4453, the dam crest elevation, around the reservoir. The dikes were designed with a crest elevation of 4453, a crest width of 30 feet, an upstream slope of 2 to 1 protected by a 24-inch layer of rock riprap on six inches of gravel bedding, and a downstream slope of 2 to 1. 'L'he Riverside Dike would be a 6,100- foot extension of the left abutment of Narrows Dam constructed generally in conjunction with the south bank of the existing Riverside Canal. Relocated State Eighway 144 would be on its crest. The 475- foot-long Saddle Dike would be located about one-half mile south of the right abutment of Narrows Dam on its projected axis. The Layton Dike would begin about one mile south of the right abutment of Narrows Dam near the southeast edge of the existing Bijou Reservoir No.2. It would extend 6,160 feet around the south edge of that reservoir and would be north of the existing Layton Lateral. Electrical power for operating the facilities at the damsite could be supplied by either the Morgan County Rural Electric Association or the Public Service Company of Colorado since both organizations have transmission lines in the vicinity. No arrangement has been made for service with either, but the plan assumes that such an arrangement will be (Dnsummated at an appropriate time. The plan does provide for approximately three-fourths of a mile of 13.8 kv. line to be con- structed from the point of delivery to the outlet works and to per- manent operating facilities. Relocations in the reservoir area would involve the main Chicago- Denver line of the Union Pacific Railroad, State Eighway 144, a county road, power and telephone lines, oil and gas pipelines, and a 30-grave cemetery. Subject to negotiations with the railroad company, it is planned to construct 32.22 miles of new line around the north side of the reservoir to replace 30.34 miles of existing railroad along the north bank of the river. For estimating the relocation cost, current standards of construction as furnished by the Railroad Company were used. Credit for betterments over equivalent replacement will be obtained during negotiation. Salvage value of the old line also should reduce the total cost of the relocation. The cost estimate for relocation of State Eighway No. 144 reflects some improvement of the road to bring it to current standards. The additional cost over that for equivalent replacement would be $139,000. Morgan County is reconstructing the county road to be relocated and the cost of relocation is based on the county standards. 20
