Public Notices

  • NWO-2021-01052-MTH

    Expiration date: 10/15/2021

    The U.S. Army Corps of Engineers, Omaha District, (Corps) is evaluating a permit application to stabilize an eroding bank using riprap. Trees and brush that will be removed to install the riprap will be used to create log jams and brush piles at the heads of the floodplain overflow channels to slow velocities when overbank discharges occur, which would result in permanent and temporary impacts to approximately 1,540 linear feet (LF) of the Jefferson River and 0.042 acre of wetlands which were identified during the wetland survey as waters of the United States.
