<br /> <br />Enclosure 2. Responses to Questions from Mr. Lockhart, Pikes Peak <br />Group, Sierra Club (continued) <br />When using NWP#14 a permit term requires that "The crossing ie <br />culverted, bridged, or otherwise designed to prevent the <br />restriction of, and to withstand, expected high flows ...." Also, <br />Section 404 Only Condition #6 (Obstruction of High Flows) requires <br />"TO the maximum extent practical, discharges must not permanently <br />restrict or impede the passage of normal or expected high flows or <br />cause the relocation of the water ...." The existing road <br />crossings have withstood several major flood events since they were <br />constructed with only minor damage to the right downstream <br />approachway at the lower road crossing. The lower crossing also <br />played a role in the capture of sediment immediately upstream of <br />the crossing due to a backwater effect but this effect was minor <br />compared to the total amount of sediment deposited upstream of the <br />crossing due to the widening of the valley floor upstream of the <br />crossing. Therefore, I conclude that the crossings fully comply <br />with both the nationwide permit term and condition described above. <br />ANDREW J. ROSENAU <br />Chief, Regulatory Branch <br />-2- <br />
