It shows that all four concepts <br />have a BC ratio greater than 1.0. The ratios presented in Table 20 were calculated using itemized <br />benefits and costs derived from a year 2040 forecast with traditional assumption about <br />telecommuting. Table 20 analyzes the sensitivity of these ratios to increased levels of telecommuting. <br />It shows that additional telecommuting reduces the present value benefits of Concept 2, but all four <br />concepts retain a BC ratio greater than 1.0. <br />Table 20: Northwest Metro Mississippi River Crossing Feasibility Analysis; Benefit Cost -Ratios <br />Concept 1 Concept 2 Concept 3 Concept 4 <br />Traditional <br />Forecasts <br />Present Value of Benefits $166M <br />Present Value of Costs $165M <br />Benefit -Cost Ratio 1.0 <br />$293M <br />$215M <br />1.4 <br />$95M $115M <br />$83M $89M <br />1.1 1.3 <br />Telecommute <br />Forecasts <br />Present Value of Benefits $168 $226 $97 $117 <br />Present Value of Costs $165M $215M $83M $89M <br />Benefit -Cost Ratio 1.0 1.1 1.1 1.3 <br />Northwest Metro Mississippi River Crossing Feasibility Analysis <br />
