<br />Four alternatives were evaluated for providing the maximum day demand of 3.R <br />MGD in year 2025 at the palisade water plant. A capacity analysis and preliminary <br />design was prepared for each action alternative. Comparative costs of the action <br />alternatives are as follows: <br /> <br />Alt. 1. <br />Alt. 2. <br />Alt. 3. <br /> <br />Install a larger non-pressllrized pipe (12" dia) . . . . . .. $1,242,000 <br />Install a larger pipe operating under pressure (10" dia) .. $1,683,000 <br />Replace the existing pipeline with a same-size pipeline (8" dia.) <br />and install an equalizing reservoir at the Wye (67 AF) $1,677,900 <br />A 'No-Action' plan. <br /> <br />Alt. 4. <br /> <br />Ute Water Conservancy District has expressed interest in cost sharing on a larger <br />pipeline than that needed by Palisade, for the purpose of supplying peak flows of 4 to 10 <br />mgd during emergencies. If the two entitles agree to this, Ute Water will provide the <br />funds needed to upgrade the pipe size. <br /> <br />A decision matrix was used to evaluate 16 economic and non-economic factors for <br />each alternative. Each factor in the decision matrix was scored on a scale from 1 to 5. <br />Alternative 1 (larger diameter non-pressure replacement pipe) was the highest scoring <br />alternative, and is the system recommended in this report. <br /> <br />The proposed project will consist Of installation of 22,000 feet of 12-inch ductile <br />iron pipe, from the outlet pipe on Cabin ~eservoir to the Wye connection. It will be <br />installed in an access road which runs thrc,ugh the narrow rocky canyon through which <br />Cottonwood Creek flows. Since the pipelIDe flows continuously, particularly during <br />winter months, a relative shallow depth of 3 feet is feasible; however, difficult subsurface <br />conditions are anticipated. There will be a moderate amount of both rock excavation and <br />imported bedding. Air vents and air rel~ valves will be placed at strategic locations <br />on the pipeline. <br /> <br />Much of the pipeline route is located within Federal lands administered by the <br />Bureau of Land Management (BLM). A right-of-way (ROW) permit will have to be <br />obtained from the BLM prior to construction. It is probable that an Environmental <br />Assessment will be needed for this purpoSe; however, the local BLM office did not <br />anticipate any significant obstacles. The standard review process will take several <br />months, and requires input from all affected entities. <br /> <br />The total estimated cost of the Cottonwood Creek Pipeline Project is $1,242,500, <br />which includes construction, engineering and environmental assessment. The Town of <br />Palisade is requesting a loan for 75 percent of the total cost, or $931,875. The Town of <br />Palisade has previously been approved for a $750,000 loan for this project at 4% interest <br />for 30 years; a second loan in the amount of $181,875 is being requested ($931,875 - <br />$750,000 = $181,875). The requested term of the second loan is 4.0% at 30 years. <br />Since the terms for both loans are the saIl1e, payments will be combined (although <br />separate tabulations will be kept on paper.) <br /> <br />A:.~WPD <br /> <br />1-2 <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />
