<br />John Peroulis & Sons Partnership <br />May 20-21, 2002 <br /> <br />Agenda Item 120 <br /> <br />Feasibilitv Studies <br />Brian Len, P.E., of Northwest Colorado Consultants, Inc., has updated the feasibility study in <br />accordance with CWCB guidelines. The study includes the revised project scope and an <br />assessment of alternatives available for rehabilitation of the Martin Cull Dam. <br /> <br />The John Peroulis & Sons Partnership <br />The JPSP is a General Partnership registered in the State of Colorado consisting of 6 members <br />of the Peroulis family. The Partnership was formed for the purpose of engaging in general <br />investment and management activities involving ranching and farming. The JPSP has the <br />power to take on debt, to pledge collateral for that debt, and is not subject to TABOR. <br /> <br />Water RiClhts <br />The Partnership owns water storage rights in the Martin Cull Reservoir in amount of 250 ac-ft. <br />State Engineer Records indicate the reservoir was used to capacity during the period 1997 <br />through 2000. (The reservoir was not used in 2001 due to the storage restriction.) <br /> <br />Prior to the year 2001, the Partnership has consistently exercised the Martin Cull storage right <br />when water was available, filling the reservoir during the winter and spring and discharging <br />during the irrigation season. Because of the unusually low snow-pack, there is not enough <br />water to fill the reservoir in 2002. <br /> <br />Proiect Description <br />Three alternatives were analyzed in the feasibility study: <br /> <br />1. No Action <br />2. Reconstruction of the upstream slope and repair of the outlet IJIIllIE estimated) <br />3. Complete dam reconstruction and enlargement ($335,000 estimated) <br /> <br />Alternative 2, Reconstruction of the upstream slope and repair of the outlet, was the preferred <br />alternative for the initial loan, and included the minimum repair necessary to place the dam <br />back in operation. The Partnership now prefers to incorporate a small enlargement of the <br />reservoir into the project. Alternative 3, Complete dam reconstruction and enlargement will <br />provide a permanent solution to the problem and additional economic benefit to the Partnership. <br />It is considered the preferred alternative. The no-act/on alternative was considered <br />unacceptable since it would mean that the reservoir could not be filled and used for irrigation. <br /> <br />Selected Alternative 3 consists of reconstructing the upstream face of the embankment and <br />bringing the downstream face of the embankment to a stable configuration by incorporating a <br />blanket drain and support berm along the toe of the dam. The embankment will be widened to <br />accommodate a 2-foot height enlargement, while maintaining a final crest width that conforms <br />to State Engineer rules and regulations. The existing outlet will be abandoned and replaced with <br />a new structure at the left abutment. The emergency spillway will be rebuilt with an overflow <br />elevation raised 5 feet, while maintaining 5 feet of freeboard to the crest of the enlarged dam. <br />The spillway will also incorporate a concrete cutoff wall to prevent back cutting. This alternative <br />will provide the owner with a stable embankment, which should increase the design life of the <br />structure by at least 50 years and provide additional storage. <br /> <br />The implementation schedule calls for completion of financing arrangements and final <br />engineering design in spring 2002. Work will start in spring 2002 and be completed by late fall <br />2002. <br /> <br />2 <br />
