<br />PROJECT DESCRIPTION AND ALTERNATIVES <br /> <br />The purpose of this proj ect is for the Beaver Reservoir <br />Company (BRC) to have on-site fill materials, if of acceptable <br />consistency and stability, or hauled-in materials placed upon the <br />lower edge of the liner installed in 1995 in a previous project <br />funded by the Colorado Water Conservation Board (CWCB) to stabilize <br />that edge of the liner and prevent undermining and erosion beneath <br />the liner. In addition, the project will include the replacement <br />of the existing old, malfunctioning and unreliable hydraulic valve <br />and gate on the intake structure so as to be able to safely control <br />the continued releases of irrigation water from the Beaver <br />Reservoir to its users. <br /> <br />Alternatives Considered: <br /> <br />1. Liner berm: <br /> <br />a. On-site fill materials <br />availability and lower cost of placement; <br /> <br />preferred because of <br /> <br />b. Hauled-in materials - to be used if on-site materials <br />are of unacceptable consistency or need supplemented, at higher <br />cost for transportation and placement. <br /> <br />2. Valve, gate and intake structure: <br /> <br />a. Repair old hydraulic gates or valves <br />because of excessive expense and unreliability; <br /> <br />rejected <br /> <br />b. Remove existing structure and create a new one - <br />rejected because of excessive expense and time for construction; <br /> <br />c. Construct a new structure around and above existing <br />structure to accommodate a manually operated gate with a new stem <br />and air vent - selected because cost would be more affordable, time <br />required for construction compatible with time of opportunity <br />likely available, and the manually operated gate being less <br />expensive, more reliable and easier to maintain. <br /> <br />The selected alternative involves raising the height of the <br />intake structure about 10 feet, placing fill material around the <br />new structure and installing a new 24-inch gate on top of the <br />structure, along with a new stem running up the face of the dam to <br />a stabilized control site. <br /> <br />The engineering firm of Golder Associates, Inc., (Golder) has <br />prepared a description of the project, engineering design sketches <br />and cost estimate of the project, copies of which are attached <br />hereto and included in Appendix D. <br /> <br />Page 12 of 15 <br />
