<br />. <br /> <br />. <br /> <br />. <br /> <br />e <br /> <br />e <br /> <br />BT Project. The existing dam is an earthfill embankment with a crest length of about 1,000 <br />feet. <br /> <br />The recommendations of the 1988 Phase II alternatives analysis included: purchase of <br />additional C-BT units, additional water conservation measures, and the expansion of Green <br />Ridge Glade Reservoir to a capacity of3,500 acre-feet. The major factors influencing the <br />City's selection of a 6,000 acre-foot reservoir capacity are: (1) the amounts of emergency <br />storage and operating storage required for the long run, (2) 6,000 acre-feet represents the <br />optimum capacity of the site, and (3) enlarging the reservoir to its optimum capacity at a <br />future date would be more costly. <br /> <br />// <br /> <br />For the long run, the City estimates it will require about 2,000 acre-feet for emergency <br />storage in addition to the 3,500 acre-feet recommended in the Phase II report for operational <br />storage for a total capacity of almost 6,000 acre-feet. Also, it should be noted that 6,000 <br />acre-feet is the ultimate capacity of the Green Ridge Glade site and that a future dam raise <br />would likely be more expensive on a per acre':'foot basis than enlarging now to 6,000 acre- <br />feet. <br /> <br />The City anticipates leasing a portion of the capacity of the expanded reservoir to agricultural <br />water users in the Loveland area. A very preliminary estimate is that 2,000 acre-feet might <br />be leased to agricultural interests over the next ten to twenty years. <br /> <br />The Woodward-Clyde feasibility study included the formulation and evaluation of seven <br />alternatives for raising the existing earth embankment dam or constructing a new dam at a <br />downstream location to obtain a 6,000 acre-foot reservoir. The analysis also included a <br />number of options for a new outlet tower and spillway as well as relocation of an existing <br />county road. <br /> <br />The detailed alternatives analysis in the feasibility study resulted in the selection of two final <br />options for raising the existing dam. The difference between the two selected options, which <br />will be analyzed in more detail in final design, is in the possible use of the core of the <br />existing dam. The feasibility-level cost estimates indicated that both options would cost <br />about $19.2 million. Adding the costs of planning and environmental studies results in a total <br />cost estimate of about $19.7 million. <br /> <br />The project schedule calls for design to begin in 1998 with construction to begin in the year <br />2000. Construction is expected to take two years. <br /> <br />Table 3 summarizes several major characteristics of the proposed project. <br /> <br />3 <br />
