<br />Jackson lake Resef\loir and irrigation Co. <br />November 22-23,1999. Agenda Item 13b. <br /> <br />Proiect Descriotion <br />Four alternatives were analyzed in the feasibility study: <br /> <br />\ <br />, <br /> <br />e <br /> <br />1. The nO-action alternative. <br />2. Continue a level of minimum maintenance. <br />3. Rehabilitate oniy the river diversion structure ($374,000). <br />4. Rehabilitate both the river diversion and headgate structures ($474,000). <br /> <br />Alternative 4, rehabilitate both the river diversion and headgate structures, was ruled out <br />becau!>e the head gate structure is in generally good condition and functioning satisfactorily. <br />Expenditure of the additional $100,000 could not be justified at this time. For this reason <br />Alternative 3 was selected, since it is considered to be a reliable approach, and is less costly. <br />The no-action and the minimum maintenance alternatives were considered unacceptable since <br />both would eventually result in partial or total failure of the diversion and inability of the JLRIC to <br />deliver water. <br /> <br />Selected Alternative 3 involves construction of a reinforced monolithic concrete floor for the new <br />diversion structure. This concrete structure will be supported by pipe piling, and surrounded by <br />sheet piling driven into the riverbed. All wing walls and support walls will be 15 inches thick, and <br />steel reinforce(j. A 100-foot Obermeyer Pneumatic Spillway gate will be instCllled in the river <br />diversion. <br /> <br />(The project that the JLRIC plans to undertake is very similar to 2 recently completed projects, <br />also funded in part by the CWCB. The South Platte Ditch Company and Weldon Valley Ditch <br />Company rehabilitated their river diversion~ in 1996 and 1997 respectively. Both projects . <br />included the Lise of Obermeyer Pneumatic gates, and both have operate(j well. The Sterling <br />Irrigation Company also has CWCB loan approval and will complete a similar project in fall <br />1999.) <br /> <br />The implementation schedule calls for completion of financing arrangements in 1999/2000, with <br />formal approval and resolution by the JLRIC ~hareholders in early 2000. Engineering design will <br />be finalized by July 2000, and construction is scheduled for completion in December 2000. <br /> <br />Financial Analvsis <br />The total estimated cost of the project is $374,000. Staff is recommending a loan of $336,600 <br />(90 percent of the estimate cost.) CWCB pOlicy allows for 90% loans to agricultural and <br />municipal low income borrowers (policy set at the November 24-25, 1997 CWCB meeting.) <br />Agriculture has not been a participant in the recent economic boom. The JLRIC will establish a <br />one-time assessment to raise the remaining 10 percent of the project cost. That assessment <br />will be $24.13 per share for 2000 only. <br /> <br />Table 1 is a summary of the financial aspect~ of the project. Annual assesshnents will increase <br />from $60 per share, to $73.28 per share with a Construction Fund loan of $336,600. This is an <br />annual assessment increase of $13.28, or $0.61 per acre-foot, based on average annual <br />diversions 34,000 acre-feet. <br /> <br />. <br /> <br />2 <br />
