PUBLIC NOTICE - - - RE: Final Notice of Proposed Activity in a Floodplain or Wetland: Taylor Bayou Project in City of Walker, Livingston Parish, Louisiana To: All interested Federal, State, and Local Agencies, Groups, and Individuals This is to give notice that the Livingston Parish Government (LPG), under 24 CFR Part 58, has conducted an evaluation of this proposed action under Louisiana Community Development Block Grant (CDBG-MIT) grant number B-18-DP-22-0001/CDFA 14.228 located in the 100-year floodplain (Zone A and Zone AE) and the Federal Flood Risk Management Standard (FFRMS) riverine floodplain/wetland, as required by Executive Orders 11988 (Floodplain Management) and 11990 (Protection of Wetlands), in accordance with HUD regulations at 24 CFR Part 55, including the decision-making procedures at 24 CFR 55.20. The extent of the FFRMS floodplain was determined using the freeboard value approach. The proposed project is located in the City of Walker, Livingston Parish, Louisiana, within the Taylor Bayou Watershed. The project area covers approximately 42.50 acres and extends approximately 2.63 miles, from approximately 30° 29’ 39.82” N, 90° 52’ 16.07” W to 30° 28’ 44” N, 90° 52’ 18” W. The City of Walker, proposes to implement flood hazard mitigation and drainage improvements to Taylor Bayou and the associated watershed through funding provided under the Louisiana Watershed Initiative (LWI) Program. The project includes the expansion of approximately 2,800 linear feet of Taylor Bayou between Interstate 12 and O’Donovan Boulevard. This section will be widened to include a 50- foot top width channel with 50-foot-wide overbank shelves on each side. These improvements are projected to raise the system’s conveyance capacity and storage in order to accommodate the increased runoff from upstream improvements and mitigating downstream impacts from the project benefit areas. To supplement this expansion, two regional detention ponds will be constructed to provide significant floodwater storage and delay peak discharge timing. The northern detention pond, located near the Canadian National Railroad, will occupy approximately 12 acres and provide an estimated 45 acre-feet of storage. The central detention pond, located near Tulip Street and Clint Street, just south of US Hwy 190 will encompass approx. 9 acres and provide an estimated 65 acre-feet of storage. Combined, these facilities will introduce over 110 acre-feet of controlled floodwater detention to the watershed. In addition to channel and detention improvements, the project will include the replacement of an undersized 7-foot corrugated metal pipe (CMP) culvert at Sutcliff Drive with a 7-foot by 6-foot reinforced concrete box culvert. This upgrade will improve hydraulic continuity and reduce backwater conditions that have long plagued upstream neighborhoods. Disturbed overbank and riverine zones will be regraded and vegetated to support restored ecological function. LPG has considered alternatives to locating the action in the floodplain and wetland, including the no-action alternative. The no action alternative was rejected because it would not address existing flood hazards or provide the drainage improvements needed to reduce risk to surrounding residences, infrastructure, and public safety. Following agency coordination, review of alternatives, and the early public notice period—during which no comments were received—LPG determined that there is no practicable alternative to the proposed action in the floodplain and wetland, and that the proposed action includes measures to minimize adverse impacts and preserve natural floodplain values to the maximum extent practicable. There are three primary purposes for this notice. First, people who may be affected by activities in floodplains and those who have an interest in the protection of the natural environment should be given the opportunity to express their concerns and provide information about these areas. Second, an adequate public notice program can be an important public educational tool. The dissemination of information about floodplains can facilitate and enhance Federal efforts to reduce the risks associated with the temporary impacts to the special areas. Third, as a matter of fairness, when the Federal government determines it will participate in actions taking place in floodplains, it must inform those who may be put at a greater or continued risk. Written comments must be received by Carrie Schott at ELOS Environmental on behalf of Livingston Parish Government at the following address on or before March 22st, 2026, during the hours of 8:00 AM and 5:00 PM.
