NAME OF APPLICANT: Terrebonne Levee & Conservation District, c/o: GIS Engineering, LLC, 2503 Petroleum Drive, Suite 110, Houma, Louisiana 70363.
LOCATION OF WORK: Located in Terrebonne Parish, along La. Highway 182, Bayou Black and Geraldine Road, near the communities of Houma and Gibson, Louisiana, (lat. 29.590575, long. -90.8309972), as shown within the enclosed drawings. (Hydrologic Unit Code 8090301, Barataria Watershed).
CHARACTER OF WORK: This proposal is for Department of The Army authorization to construct four flood protection levees referred to as the Bayou Black Barrier Levee project (BBBL), Reaches 1, 2, 3, and 4, all as part of the Morganza to Gulf Flood Protection System. The project was originally placed on 20-day public notice (PN) on October 11, 2021. Due to updates on the overall BBBL proposal, combination of multiple levees and applications into a single application, and the length of time since the original posting, a secondary PN is being issued. The project stretches from LA 182 in Gibson heading southeasterly towards the Minors Canal outfall ending at the Gulf Intracoastal Waterway (GIWW). The project includes construction of an approximate 19 mile long levee system with a proposed barge gate and gate section along the GIWW, and is intended to help prevent flooding of human habitable areas, commercial properties, agricultural areas, and to maintain and regulate drainage channels within the protected area. Fill operations includes the deposition of approximately 772,698 cy of material, and excavation of approximately 7,940 cy of on-site material. The levees will be constructed to Elevation of +7.0 and will have a 3H:1V side slope. The project includes a total of 60.68 acres of direct impacts to jurisdictional Bottomland Hardwoods wetlands and 47.63 acres of direct impacts to jurisdictional Cypress Tupelo wetlands. All 4 levee reaches are described further in detail in the enclosed drawings. If a Department of the Army permit is found to be in the public interest, the applicant has proposed to mitigate unavoidable wetlands impacts at an approved and acceptable mitigation bank or banks within the N.O. District.
