408-NWO-2024-0057

Expiration date: 8/5/2024

The purpose of the proposed action is to remove BNSF Railway Company (BNSF) Bridge 2001-518.9 from the Big Sioux River due to a significant storm event that caused the structure, managed by the USACE Omaha District, to be damaged and dislodged from the pier in the center of the river. BNSF proposes to construct temporary access for bridge removal activities through the North Sioux City Right Bank Levee on the west side; and separately construct temporary access on the east side. BNSF proposes to maintain levee continuity during levee excavation, by constructing a ring levee in a manner to preserve flood protection for North Sioux City should a moderate or major flood event occur on the Big Sioux River during levee excavation operations and access to the river for cleanup and removal of the storm damaged structure within the river. Upon completion of the ring levee the access path and causeway will be constructed in the Big Sioux River. BNSF’s plans for the new bridge replacement / construction will be submitted to USACE and the local levee Sponsors in a future separate Section 408 request and Section 404 application. Only project elements that would alter the Federal Project are within the review scope for the Section 408 permission request.
