State Route 12 Pavement Rehabilitation Project
Solicitation # 04-4W230
Caltrans plans to rehabilitate pavement and improve infrastructure along State Route 12 between postmile 0.0 to 3.31 in Napa County and postmile 0.0 to 7.90 in Solano County, including drainage enhancements, installation of pedestrian islands, and updates to various system elements. The project is being evaluated under a proposed Negative Declaration, indicating that Caltrans anticipates no significant environmental impacts from the proposed work. Based on an Initial Study, the project is not expected to substantially affect aesthetics, agriculture, air quality, cultural resources, energy, geology, hydrology, land use, mineral resources, population, housing, public services, recreation, tribal cultural resources, utilities, wildfire risk, greenhouse gas emissions, hazards, noise, transportation, traffic, or biological resources. While the project may result in minor or less than significant effects in certain areas, it is not anticipated to trigger the need for an Environmental Impact Report. The project is formally listed under the title State Route 12 Pavement Rehabilitation Project with a forecast posting date of June 24, 2026, and is managed by Caltrans District 4 – Bay Area/Oakland. Public and agency comments may still influence the final determination of the Negative Declaration, and the decision is not yet final. The primary point of contact for environmental inquiries is Matthew Coughlin, Environmental Scientist, reachable via email or phone. The project’s official documentation and updates can be accessed through the provided online link.

Solicitation # 04-0AA53
The Solano State Route 12 Pavement Preservation project (EA 04-0AA53) is a Caltrans District 4 initiative located in Solano County, California, spanning State Route 12 between postmiles 14.10 and 20.68. With a total programmed cost of approximately 37.388 million dollars, the project focuses on comprehensive roadway improvements including pavement dig-outs, cold planing, asphalt concrete overlay, and the installation of AC dikes. Additional scope elements include shoulder widening, drainage improvements, the upgrade of metal beam guardrails, traffic signing panel updates, and the installation of centerline and shoulder rumble strips and pavement delineation. The project is governed by the 2025 Caltrans Standard Specifications, with specific requirements for job site management and the handling of hazardous waste and contamination. Environmental compliance is a primary focus, as evidenced by a Mitigated Negative Declaration under CEQA and the requirement for various permits, including a 1602 Lake and Streambed Alteration Agreement and a Section 401 Clean Water Act Permit. Strict protocols are in place for the delineation of Environmentally Sensitive Areas using high-visibility markings and the implementation of biological inspection measures for pipes, culverts, and open trenches. The project also adheres to Title VI of the Civil Rights Act and the Americans with Disabilities Act to ensure non-discrimination and accessibility.
