12-0V730 Minor B Signs and Pavement Delineation Project

The project, identified as 12-0V730 Minor B Signs and Pavement Delineation Project, is a Caltrans District 12 initiative in Irvine, California, focused on upgrading traffic infrastructure along State Route 261 at three ramp locations: SB SR-261 to Portola Pkwy, NB SR-261 to Irvine Blvd, and SB SR-261 to Irvine Blvd. Work includes installing new signage on existing signal mast arms and wooden poles, refreshing and upgrading pavement striping and delineation, and converting existing crosswalks to high-visibility ladder-style markings. All activities occur strictly within state right-of-way with no trenching, vegetation removal, or DSA-related work required; ground disturbance is limited to the installation of 6x6 posts with a maximum 5-foot embedment. Temporary traffic control measures, including PCMS signs and planned detours, will be implemented during ramp closures. The project is subject to Caltrans Standard Specifications, MUTCD guidelines, and California water quality regulations, including the Statewide NPDES Permit and regional water board requirements. A Water Pollution Control Program is required since the disturbed area is less than one acre. Environmental compliance is a critical component, with treated wood waste from sign post removal requiring strict handling, labeling, and disposal protocols as mandated by California Health & Safety Code §25230 et seq. Waste must be stored in water-resistant containers or on protected surfaces, labeled with seven specific elements including contract number, district information, and contractor contact details, and transported with signed shipping records documenting origin, destination, weight, and dates. Disposal must occur within 90 days if stored uncovered or 365 days under permanent cover at permitted California facilities. GHG emissions from construction are estimated at 5 metric tons CO₂e and must be calculated using Cal-CET 2021, with reporting required under Caltrans specifications. Soil disposal must comply with SSP 7-1.02K, and the waste is classified as non-hazardous with respect to lead, which must not exceed 1,000 mg/kg. No barcoding or electronic tracking systems are required, though paper-based shipping records are mandatory. No contract value, pricing, or evaluation factors are available in the documentation, and while the project is posted as a forecast, it lacks a formal solicitation number, contract type, or payment instructions. Oversight and compliance are coordinated through the Caltrans District 12 Engineering Office
