The following <br /> alternatives were considered: <br /> Alternative 1 - No-Action: This alternative was considered unacceptable as it would cost the City 699 <br /> acre-feet of raw water storage. <br /> Selected Alternative 2 - Dam Rehabilitation:This alternative was selected because it will address <br /> the dam safety concerns and preserve the City's storage right for drought mitigation and irrigation. It <br /> involves removal of several feet of material on the downstream face of the dam, removal of the <br /> existing toe drain system, installation of a blanket filter on the downstream face, installation of a new <br /> toe drain system, installation of a buttress on the downstream face, and installation of new <br /> piezometers and monuments. <br /> The cost associated with this alternative is $1,153,800 as shown in Table 2. <br /> TABLE 2: PROJECT COST <br /> Task COST <br /> Design Engineering $126,500 <br /> Construction $964,100 <br /> Construction Management $15,000 <br /> Contingency $48,200 <br /> TOTAL $1,153,800 <br /> TABLE 3: PROJECT FUNDING SUMMARY <br /> Task Cash In-Kind Total <br /> City of Grand Junction $53,800 n/a $53,800 <br /> CWCB Loan $1,000,000 n/a $1,000,000 <br /> Sub-total matching funds $1,053,800 n/a $1,053,800 <br /> Gunnison Basin Account $25,000 n/a $25,000 <br /> WSRA Statewide Account $75,000 n/a $75,000 <br /> Total $1,153,800 n/a $1,153,800 <br />
