Expiration date: 6/9/2022

Interested parties are hereby notified that an application has been received for a Department of the Army Section 408 permission for certain work at or near a federally-authorized flood risk management project of the United States, as described below and shown on attached figures. Written comments are being solicited from anyone having an interest in the requested alteration. Comments will become part of the U.S. Army Corps of Engineers’ (USACE) administrative record and will be considered in determining whether to approve the request. Comments supporting, opposing, or identifying concerns that should be considered by the USACE in its decisions process are all welcome. Comments providing substantive information or a rationale for the commenter’s position are the most helpful. This public notice is not a paid advertisement and is for public information only. Issuance of this notice does not imply USACE endorsement of the project as described.

REQUESTER: In compliance with 33 U.S.C. 408 (Section 14 of the Rivers and Harbors Act of 1899; hereinafter Section 408), Sny Island Levee Drainage District requested permission to modify a portion of their Reach 1 Levee, an existing federally-authorized flood risk management project.

LOCATION: The proposed project is located along the mainstem portion of the Reach 1 Levee in Pike County, Illinois.

REQUESTER’S PROPOSED ACTION: The proposed project would construct a seepage berm along approximately 2.6 linear miles of the mainstem portions of the Sny Island Levee Drainage District Reach 1 Levee in Pike County, Illinois from levee stations 424+00 to 555+00. Seepage and large boils formed in this area during the 2019 Flood. The proposed seepage berm would reduce seepage rates and improve levee slope stability, thus reducing pumping rates. Material to construct this project would come from the existing Cave Hollow Dredged Material Placement Site near River Mile 305.6 within Reach 1 of the Sny Island Drainage Levee District. No additional dredge, borrow, or excavation would be required as this site contains enough material.
