Highway Maintenance Culvert Repair Project

Caltrans District 7 in Los Angeles is forecasting a highway maintenance project to restore ten deteriorating drainage culverts to current safety standards across Routes 5, 5S, and 14. The scope of work includes the installation of cure-in-place pipeline lining, concrete invert paving, and the repair of joints and inverts. Specific work sites are located on Interstate 5 between post miles R51.43 and 80.00, on I-5S at post mile C45.49, and on State Route 14 between post miles R28.93 and R48.61. The project is designed to prevent erosion, ponding, and flooding without requiring new right-of-way acquisitions or public utility relocations. The project is classified under NAICS code 237310 and has been determined exempt under CEQA and categorically excluded under NEPA. Contractors must adhere to strict environmental and safety mandates, including the South Coast Air Quality Management District Fugitive Dust Implementation Rule 403 and the 2022 Standard Specifications for hazardous waste analysis. Key requirements include the preparation of a Lead Compliance Plan, adherence to overnight noise limits of 86 dBA at 50 feet, and the implementation of stormwater and erosion best management practices. Additionally, the contractor must conduct pre-construction nesting bird surveys and specialized wildlife surveys for the Crotch's bumble bee and coast horned lizard within 72 hours of starting work.
