There <br />are 14 shareholders and 320 shares of stock. The LliDC has the power to set annual <br />assessments to be paid by the shareholders and thei power to refuse to deliver water to <br />shareholders that fail to pay their assessments. <br /> <br />e <br /> <br />Water Riahts <br />The LLDC has rights to divert 39.9 cfs from the South Platte River under an 1882 decree. The <br />LLDC diverts on average approl(imately 6,650 acre-f~et of water per year through their ditch. <br /> <br />The 14 shareholders of the LLDC also have decrees ion 13 wells used for irrigating the 2,070 <br />acres under their system. These wells are currently augmented through GASP. The LLDC <br />diverts on average approximately 1,200 acre-feet of water per year through thes.e 13 wells. <br /> <br />Proiect DescriDtlon <br />Three alternatives were considered, including: <br /> <br />1. Don't do the project and continue to rely upol'1 the existing diversion. <br /> <br />2. Completely rebuild the diversion using the be~t available technology. <br /> <br />3. Rebuild only that portion of the diversion necessary to allow for more efficient diversions. <br /> <br />Alternative 3, Rebuild only that portion of the diversion necessary to allow for more efficient <br />diversions, was selected because it was the least cost option that provided a permanent <br />solution to the problem. . <br /> <br />. <br /> <br />Selected Alternative 3 consists of the following: <br /> <br />· Two mechanical lift gates will be Constructed. Each gate will be approximately 20 feet in <br />length and four feet in height. . <br /> <br />· Three sections of concrete rollover wall will be constructed. Each section will be <br />approximately 20 feet in length and five feet in height. <br /> <br />· A new concrete floor will be constructed under' the gates and rollover sections. The floor <br />will be six inches thick through the center andi flared toward the edge. <br /> <br />; <br />. Sheet piling will be placed along the upstream edge of the project to prevent under <br />currents from eroding under the new improvements. <br /> <br />Cost Estimate <br /> <br />Item <br />Planning and Design Costs <br />Construction Cost with Contingency <br />Total Cost <br /> <br />, <br />, <br />Eslimate'd Cost <br />$ 1,500 ! <br />$71.000 I <br />$72,500 ' <br /> <br />The implementation schedule calls for completion of financing arrangements and final design <br />in March 2003.
