Replace/install new transportation management systems in AMA, CAL, MPA, MER, SJ, and TUO counties on routes 48, 88, 99, 108, 120 & 140

The California Department of Transportation (Caltrans) District 10 in Stockton is implementing project 10-1K670 to replace and install new Traffic Management System (TMS) elements and construct maintenance vehicle pullouts (MVP) across 12 locations. The work is situated within existing Caltrans right of way on Routes 49, 88, 99, 108, 120, and 140, covering Tuolumne, Amador, Calaveras, Merced, Mariposa, and San Joaquin counties. Key deliverables include the removal of existing Hazard Advisory Radio (HAR) components and the installation of new units. Construction activities involve ground disturbance up to a maximum depth of 10 feet, potential vegetation clearing, and the reuse of excess soil for the development of the maintenance vehicle pullouts. The project is classified as a categorical exemption under CEQA and NEPA, as it is determined to have no significant environmental impact on protected species, historic properties, or hazardous materials. Operational requirements include the performance of night work and strict adherence to Caltrans Standard Specifications regarding air pollution, dust control, noise control, and bird protection. The project is managed by the Stockton office, with environmental oversight provided by the Senior Environmental Planner and Project Manager to ensure compliance with all state and federal environmental regulations.
