,I 'r , .' , CHAPTER 2 - ALTERNATIVES o 0- -J en No Action The No Action alternative (i.e., not laking action to reduce salinity from the Unit) is described in the FR/FES. Under it, no canals or laterals would be improved using salinity control funds. 1984 Plan The 1984 Plan was the recommended alternative of the FR/FES, and was named ."Plan A-2." It's major features were: . Concrete-line 59 miles of canals and 195 miles of laterals east of Uncompahgre River; . Conslnlct improvements over a 7-year period under contracts with private fmns; . Acquire/develop 2,100 acres of habitat replacement land for management by a non- Federal agency. The plan assumed the canals and laterals would be lined with a thin, 3-inch, layer of concrete. Where necessary, flexible lining material would be used. Habitat replacement was to compensate for the loss of an estimated 610 acres of wetlands, and reduction in quality to 1,260 acres. Replacement areas were to be located primarily along the Uncompahgre River. The FR/FES cost estimates used January 1981 prices. Table 1 updates the total cost reported to January 1994 price levels. Habitat replacement costs for the canals vs. laterals were not separately identified. A later inventory of wetlands showed about 57 percent of the costs could be attributed to lining only the laterals. Table 1 - Update of 1984 Plan Cost &timates Jan. 1981 Jan. 1994 Feature Price Level Price Level Lateral Lining $68,600,000 $90,450,000 Habitat Replacement, Laterals $2,750,000 $2,998,000 TOTAL $71,350,000 $93,448,000 This total capital investment cost was amortized over a 50-year period at 7 3/8 percent interest to show annual costs. The annualized cost for the laterals at 1981 price levels would have been about $5,260,000. Updated to 1994 price levels and assuming an 8 percent interest rate, annual costs of the 1984 Plan would be about $7,640,000. 5
