<br />Town of Ridgway Agenda Item 13a, <br />November 22-23,1999 Updated December 1, 1999 <br /> <br />Proiect Description <br />Four alternatives were analyzed in the feasibility study: <br /> <br />1. The no-action alternative <br />2. Expand the treatment plant and use existing lines for irrigation ($285,000). <br />3. Build reservoirs on Town parklands to use as a raw water supply. <br />4. Construct a new raw water irrigation system ($108,000). <br /> <br />Alternative 3, build reservoirs on Town parklands, was ruled out because of the difficulty and <br />uncertainty of the water supply to fill the reservoirs, and because of the relatively high annual <br />costs associated with pumping from the reservoir to irrigate the park. Alternative 2, expand the <br />treatment plant, was ruled out based on cost. The no-action alternative was considered <br />unacceptable since it would mean the new park could not be developed as planned. <br /> <br />Selected Alternative 4 involves construction of a new raw water pipeline extending from the <br />Town's reservoirs to the new park location. The pipeline will be 10" in diameter and includes a <br />pressure relief station. The pipeline will be sized so that raw water irrigation can later be <br />provided to residents as Phase 2 of the project. Initially, about 50 acre-feet per year will be <br />diverted for park irrigation. <br /> <br />The implementation schedule calls for completion of financing arrangements in 1999/2000. <br />Engineering design will be finalized by February 2000, and construction is scheduled for <br />completion in August 2000. <br /> <br />Financial Analvsis <br />The total estimated cost of the project is $108,000. The Town is requesting a loan of $77,000 <br />(about 71 percent of the estimate cost), for a duration of 20 years. The Town will pay for its <br />share from current reserves. <br /> <br />Table 1 is a summary of the financial aspects of the project. Ridgway's median household <br />income was within 80% of the 1990 statewide median, qualifying the Town for a loan at the <br />standard municipal rate. A construction fund loan for $77,000 at 4.75% for 20 years would have <br />an annual payment of about $6048 ($6,653 with a 10% loan reserve). This amounts to a per <br />customer cost of just $19.01 per year, or $1.58 per month (350 customers.) The current water <br />rate ($22/month) is sufficient, and no rate increase will be necessary to fund this project. <br /> <br />Table 1.
