Illinois Central Railroad Co. (ICRR) has submitted a request to replace its Bonnet Carré Spillway Bridge, in St. Charles Parish, Louisiana (“undertaking”). This request for permission to modify a U.S. Army Corps of Engineers Project is being reviewed under Section 14 of the Rivers and Harbors Act of 1899,codified in 33 U.S.C. 408 (“Section 408”). Section 408 authorizes the Secretary of the Army to grant permission for the alteration or occupation or use of a USACE project if the Secretary determines that the activity will not be injurious to the public interest and will not impair the usefulness of the project. Evaluation factors employed by the U.S. Army Corps of Engineers, New Orleans District (CEMVN) for Section 408 reviews, are detailed in Public Notice/File Number 17-0244. This consultation is specific to evaluation factor 3(e). CEMVN has determined that there is one historic property, the 1934-1935 ICRR Bonnet Carré Spillway Bridge, as defined in 36 CFR 800.16(l) within the APE. As the proposed undertaking calls for the near complete demolition of this historic property, CEMVN has determined that implementing the undertaking would directly alter the characteristics of this historic property that qualify it for inclusion in the NRHP in a manner that diminishes the integrity of the property’s location, design, setting, materials, workmanship, feeling, and association. Therefore, CEMVN has determined a finding of Historic Properties Adversely Affected for this undertaking. CEMVN proposes to conduct the initial meeting at the Bonnet Carré Spillway Project Offices, 16302 River Road, Norco, LA 70079 during the week of December 11-15, 2017. The purpose of the initial meeting will be to discuss the proposed undertaking, the historic property, and to determine the appropriate steps to avoid, minimize, and mitigate the adverse effects. Should your organization want to participate please contact Jason A. Emery, with the provided contact information on the Adverse Effect Notification Letter.
