SR-241/SR-133 Multi Asset Project

The California Department of Transportation (Caltrans), District 12, is advancing a multi-asset construction project along State Route 241 from 0.7 mile north of Oso Parkway Overcrossing to 0.4 mile north of the SR-133 Interchange, and along SR-133 from 0.2 mile north of Portola Parkway to Bee Canyon Access Road in Orange County. The project encompasses a range of improvements including pavement preservation, drainage system restoration, lighting rehabilitation, roadside enhancements, safety and mobility upgrades, and complete streets initiatives, all designed to extend the functional life of the infrastructure while improving transportation efficiency. Environmental compliance is a central component, with requirements governed by Caltrans' internal Project Feature (PF) and Standard Special Provision (SSP) systems rather than federal FAR clauses. Key environmental mandates include adherence to NPDES stormwater permits, noise limits of 86 dBA Lmax during nighttime hours, air quality controls per Caltrans Specification 14-9, and specific protocols for handling hazardous materials such as aerially deposited lead and treated wood waste. Biological protections require ESA fencing, restriction of work near sensitive habitats like California Gnatcatcher nesting zones during breeding season, and avoidance of night work without proper shielding. All construction activities are subject to inspection and acceptance by Caltrans personnel at the project site, with oversight provided by the Resident Engineer, Project Engineer, and District Paleontologist to ensure compliance with Caltrans Standard Specifications and environmental mitigation measures. A Mitigated Negative Declaration has been adopted under CEQA, with a formal Environmental Commitments Record in place to monitor mitigation implementation, and a Notice of Determination filed with the State Clearinghouse. Contractors must conduct pre-construction surveys for cultural and biological resources, complete mandatory training on cultural sensitivity, and submit site-specific plans for paint removal and ADL-contaminated soil handling during the PS&E phase. While no formal contract value, award methodology, or packaging standards are specified, the project is structured as a fixed-price arrangement typical of Caltrans public works contracts. The solicitation was posted on June 25, 2026, with public comments due by June 18, 2026, and project timelines extend through fiscal years 2024–2028. All correspondence and submissions are directed to Sunny Saroa, Associate Environmental Planner, and project documentation is accessible online via the official Caltrans portal.
