November 24-25, 1997, Board Meeting-- <br /> City of Idaho Springs <br /> Approval of a Construction Fund Authorization in amount of $825,000 to <br /> rehabilitate the Idaho Springs Reservoir, and $130,000 to convert the existing <br /> CWCB Emergency Loan to a Standard Construction Fund Loan. Total <br /> request $955,000. <br /> BACKGROUND <br /> The City of Idaho Springs (located in Clear Creek County) has applied for a Construction Fund <br /> Authorization to undertake major rehabilitation of the Idaho Springs Reservoir. They are <br /> requesting an $825,000 Authorization from the Construction Fund for this project, 75% of the <br /> estimated total cost of $1.1M). This facility is located on Chicago Creek south west of Idaho <br /> Springs (see attached map.) The dam was originally built in 1906 and has suffered from a broken <br /> outlet system, inadequate spillway, and seepage through the embankment. The reservoir has a <br /> capacity of 227 AF, but is restricted to 120 AF by the State Engineer due to these safety <br /> concerns: <br /> In 1995, the Chicago Creek Reservoir experienced a failure of the outlet valve, and the City's <br /> raw water intake on Chicago Creek was also damaged. The City made repairs to these facilities <br /> in 1996, funded in part by an Emergency loan from the CWCB in amount of $130K. This <br /> CWCB loan is an interest only loan, with a balloon payment at the end of 3 years (in 1999.) It <br /> was originally anticipated that this Emergency loan would be rolled into the larger project loan, <br /> which the City is now applying for. The City wants to convert this $130,000 loan to permanent <br /> financing, amortized over 30 years. <br /> Parson's Engineering Science Inc. has completed preliminary engineering design work as well as <br /> the feasibility study. <br /> 410 <br />
