<br />4. Embankment materials removed from the existing embankment will be <br />reused and no embankment materials will need to be imported. <br />5. There are no unforeseen conditions that would to render the <br />alternatives infeasible. A better understanding of such conditions will <br />be gained during the design phase. <br />The probable cost of construction allowing for 20 percent contingencies, for the <br />proposed alternatives are summarized in Table V-1 below. The cost estimates are <br />presented in Tables V-2 though V-4. <br /> <br />Table V-1 <br />Summary of Probable Construction Costs (rounded) <br /> <br />Outlet Works Alternatives Cost <br />Alternative 1 (No Action) NA <br />Alternative 2 (Replacement) $350,000 <br />Alternative 3 (Relining) $200,000 <br />Spillway Issues Resolution <br />Alternative 1 (No Action) NA <br />Alternative 2 (DesiQn for 100-Year) $50,000 <br /> <br />Impacts with respect to the man-made environment, the natural environment, and <br />the existing social structure are equal for all the alternatives. All alternatives, with <br />the exception of the no-action alternatives can be constructed with standard! <br />construction practices and are technically feasible. The difference is cost. <br /> <br />22 <br />
