Release no. 18-022


Jackson Hole, Wyoming – The U.S. Army Corps of Engineers, Walla Walla District (Corps) invites your comments on the Draft Finding of No Significant Impact (FONSI) and Supplemental Environmental Assessment (SEA) for the Jackson Hole Flood Protection Project Operation and Maintenance (O&M) Program.

The Corps is supplementing National Environmental Policy Act (NEPA) documentation for the O&M program for the Federal and non-Federal levees that make up the Jackson Hole Flood Protection Project (JHFPP) along the Snake and Gros Ventre Rivers near Jackson, Wyoming.  The SEA evaluates current and proposed O&M actions and associated potential environmental effects that may not have been adequately addressed in the April 1990 Jackson Hole, Wyoming Flood Protection Project O&M Decision Document and Environmental Impact Statement (1990 O&M Decision Document/EIS) (Corps, 1990).  The SEA is tiered to and incorporates by reference the 1990 O&M Decision Document/EIS.  The Corps is proposing to continue to operate and maintain the JHFPP consistent with its authorized purposes, while minimizing adverse effects to the environment.

The 30-day comment period will be from March 9, 2018 through April 9, 2018.  All information and comments submitted will be included in the permanent public record.

Electronic comments may be filed directly online at: http://www.nww.usace.army.mil/Environmental ComplianceComment/ or via email to NEPANWW@usace.army.mil, inserting “Jackson Hole Flood Project” in the subject line.
