Tulsa District Regulatory Permits for Public Comment

PURPOSE:  The purpose of these public notices are to inform you of a proposal for work in which you might be interested and to solicit your comments and information to better enable us to make a reasonable decision on factors affecting the public interest.

SECTION 10: The U.S. Army Corps of Engineers is directed by Congress through Section 10 of the Rivers and Harbors Act of 1899 (33 USC 403) to regulate all work or structures in or affecting the course, condition, or capacity of navigable waters of the United States.  The intent of this law is to protect the navigable capacity of waters important to interstate commerce.

SECTION 404: The U.S. Army Corps of Engineers is directed by Congress through Section 404 of the Clean Water Act (33 USC 1344) to regulate the discharges of dredged and fill material into all waters of the United States.  These waters include lakes, rivers, streams, mudflats, sandflats, sloughs, wet meadows, natural ponds, and wetlands adjacent to other waters.  The intent of the law is to protect these waters from the indiscriminate discharge of material capable of causing pollution and to restore and maintain their chemical, physical, and biological integrity.

The basic purpose of the proposed work (State Job Piece (JP)# 32261 (05)) is to protect the existing US 62 Bridge from being undercut by erosional forces of the North Canadian River.  A water dependency determination will be made upon consideration of the basic purpose to discharge fill material (soil) into 0.09 acre of scrub shrub wetlands.

The overall purpose of this work is for public safety.  ODOT is proposing the urgent repair to protect the safety of the US 62 Bridge as a reliable transportation route between Harrah and the US 62/US 77 junction in central Oklahoma.

The construction of the bendway weirs and directional spur is proposed to redirect flow and reduce velocity, thereby moving the thalweg of the river approximately 215 feet southwest from its current location away from the banks and existing bridge to reduce the stress and erosion potential, protecting the bridge from destruction. This would be accomplished by the construction of six bendway weirs and a directional spur extending from the northeast bank of the river on the west side of the existing bridge. The bendway weirs and directional spur will be composed primarily of Type II special plain riprap rock, with sodding and turf reinforcement mat on the anchor keys into the bank. The bendway weirs and directional spur will be placed upstream (west) of the existing bridge, with four bendway weirs placed on the north bank and two bendway weirs placed on the southwest bank. The directional spur extends out along and parallel to the north abutment of the existing bridge at a 4: 1 slope down to the computed high water for a 25-year flow. The directional spur would be placed adjacent to the existing bridge, just west of the north abutment on the north bank, and keyed into the old US 62 highway grade. The bendway weirs extend perpendicular to their banks at approximately 20% of the total channel width and at an elevation less than or equal to the computed high water for a bankfull event. The typical dimensions of the bendway weirs are a top width of 10 feet sloping with 2: 1 side slopes to a bottom width of about 30 feet and an average length of about 160 feet. The directional spur has a top width 20 feet across and 2: 1 side slopes to a bottom width average of about 60 feet and length of about 230 feet. The proposed project will result in 0.47 ac (4,030 cys of rock riprap) of permanent impacts to the North Canadian River and 0.09 ac (10 cys of rock riprap) in adjacent scrub-shrub wetlands. The weir construction is expected to accumulate 1.88 ac (22,250 cys) of silt over time.
