Lake Charles, Louisiana - The City of Lake Charles has announced plans for a comprehensive wastewater system rehabilitation project spanning multiple areas within federally designated floodplains, using Community Development Block Grant Disaster Recovery funding.
The proposed project will focus on Basin A's wastewater collection system, involving the rehabilitation of approximately 91,500 linear feet of existing sewer pipes across several sub-basins throughout the city. The work includes repairs to large-diameter gravity sewer mains ranging from 15 to 46 inches in diameter, as well as smaller pipes measuring 6 to 12 inches.
City officials plan to utilize trenchless technologies for the rehabilitation work, including cured in place lining and pipe-bursting methods. Cured in place lining involves inserting and curing a felt liner inside existing pipes, while pipe-bursting uses a specialized head to pull new pipeline sections through old infrastructure.
The project areas are located within the Federal Flood Risk Management Standard floodplain, as determined using the 0.2 percent flood approach and freeboard value approach. According to Federal Emergency Management Agency Flood Insurance Rate Maps effective February 18, 2011, the work sites fall within various flood zones including shaded and unshaded X zones, A zones, AE zones, and floodway areas.
Sub-basin A-06 will see rehabilitation of approximately 28,000 linear feet of 6 to 10-inch diameter pipes, while sub-basin A-02 involves roughly 17,500 linear feet of 8 to 12-inch pipes. Sub-basin A-09 encompasses about 31,000 linear feet of 6 to 12-inch diameter infrastructure.
The Federal Flood Risk Management Standard, established through Executive Order 11988 and amended by Executive Order 13690, requires public notice and evaluation of alternatives when federal funding supports projects in floodplain areas. The standard aims to reduce flood risks and protect natural floodplain functions.
City officials emphasize that the rehabilitation work will not expand beyond existing infrastructure footprints. The current wastewater system serves these areas, and the project focuses on improving existing capacity rather than adding new facilities.
As part of the federal requirements, the city must identify and evaluate practical alternatives to locating work within floodplain areas, assess potential environmental impacts, and consider methods to minimize any negative effects on flood management and wetland protection.
The public comment period allows residents and stakeholders to express concerns, suggest alternative locations outside floodplain areas, propose different methods to achieve project goals, and recommend ways to reduce environmental impacts.
Written comments must be submitted to the City of Lake Charles Office of Community Development by September 24, 2025. Residents can mail comments to Box 900, Lake Charles, LA 70602, call 337-491-1440, or email [email protected].
Complete project documentation is available for review weekdays from 8 a.m. to 4:30 p.m. at 326 Pujo Street, as well as online at the city's official website. Mark Tizano, Community Development Director, serves as the primary contact for project inquiries.
The Community Development Block Grant Disaster Recovery program provides federal funding to help communities rebuild and improve infrastructure following major disasters. Grant number B-21-DZ-22-0001 designates the specific funding allocation for this wastewater system project.
Federal regulations under 24 CFR 55.20 in Subpart C establish procedures for floodplain management decisions and wetland protection when federal funding supports local projects. These requirements ensure public participation in decisions affecting flood-prone areas and sensitive environmental zones.
The notice serves multiple purposes beyond regulatory compliance, including public education about floodplain risks and fairness in informing residents about potential continued flood exposure when federal projects proceed in these areas.
