<br />Project Description and Alternatives <br /> <br />The purpose of this project is to provide a means for the Glenwood Irrigation Company to <br />continue delivery of irrigation water to shareholders while minimizing the possibility of a future <br />failure of their diversion structure, Three alternatives were considered: <br /> <br />1. Continue irrigation as before. <br />2, Install new headgate and wasteway structure <br />3. Move the present point of diversion, <br /> <br />Alternative No.1, Continue irrigation as before was considered unacceptable because the <br />present structure is in such poor condition that failure could affect 750 acres of irrigated land. <br /> <br />Alternative No.2, Install new headgate and wasteway structure at present location. This <br />alternative was considered unacceptable because of the higher cost. <br /> <br />The selected alternative, Alternative No.3, Replace the present structure, was chosen <br />because the present structure is near failure as wastewater is undercut by the river. Failure at <br />this time would make delivering water to the ditch impossible. <br /> <br />This project would involve installing a headwall with 3 36' headgates. This structure would be a <br />concrete headwall and rock check diversion. It would also include some earth work at the <br />present structure and on the island protecting the present ditch from the Roaring Fork River. <br />This structure is designed to withstand a 50-year flood and will have a normal life expectancy of <br />50 years. <br /> <br />The Glenwood Springs Field Office of the Natural Resources Conservation Service (NRCS) has <br />prepared a Preliminary Engineering Report, and preliminary plans and a cost estimate for the <br />structure of the project. The report, plans and cost estimate are included in Appendix D. The <br />estimated cost of the full project is $108,962. The cost breakdown is summarized in Table 1. <br /> <br />Table 1.
