Draft Supplemental Environmental Assessment for operation and maintenance repairs at Council Bend available for public review

Published July 11, 2019

Omaha, Neb. – A draft supplemental environmental assessment to evaluate the impacts of stabilizing the Council Bend chute in Pottawattamie County, Iowa is currently available for public review. This supplemental EA specifically evaluates activities required to maintain the ecological function of the chute without adversely impacting the Missouri River authorized purposes including flood risk management.

The proposed project includes constructing a 925-linear foot stone toe revetment along the east bank of the Missouri River near river mile 617.4 in Pottawattamie County, Iowa. The purpose of the project is to stabilize the chute and prevent erosion that could occur as a result of two scour holes that formed near the area during high water in 2018.

This draft supplemental EA also evaluates the impacts of operation and maintenance activities that may be required along the chute in the future in response to other extreme high water events. Activities could include riprap armoring of identified chute bank scour areas, riprap armoring along the chute bank prior to scour area development, and repair of grade control structures.

The public is encouraged to provide comments on the draft environmental assessment, which is available for viewing at: http://www.nwo.usace.army.mil/Missions/Civil-Works/Planning/Project-Reports/. Comments can be mailed to: U.S. Army Corps of Engineers, Omaha District; CENWO-PMA-C; ATTN: Dave Crane, Council Bend EA; 1616 Capitol Avenue; Omaha, NE 68102-4901. Comments can also be emailed to: cenwo-planning@usace.army.mil. Comments must be postmarked or received no later than Aug. 9, 2019.
