No Project- <br />related impacts to recreation would occur. <br />4.5.7.2 Action Alternatives <br />Table 4.5-4 presents a summary of residual impacts for each of the end-to-end Action Alternatives <br />following the implementation of the mitigation measures. <br />No Action Alternatives would have any high residual impacts. Alternative B, C, E, and G would each <br />have 1.7 miles of moderate residual impacts. The mileage of low residual impacts on recreation resources <br />would be highest for Alternative F and lowest for Alternative C. Combined no identifiable and low <br />impacts would be lowest and no moderate or high impacts would occur for the NNR Alternative <br />Overhead and Underground Design Options. <br />Table 4.5-4 Recreation Resources Residual Impact Summary by Action Alternative <br />ACTION ALTERNATIVE RESIDUAL IMPACTS (MILES) <br />NO IDENTIFIABLE LOW MODERATE HIGH <br />Alternative A <br />1a, 1b, 2a, 2b, 2d, 3a, 3c <br />64.7 miles <br />31.8 32.9 0 0 <br />Alternative B <br />1a, 1b, 2a, 2b, 2d, 3a, 3b <br />61.2 miles <br />34.8 24.7 1.7 0
