AI Contract Overview

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.

A detailed description of this work can be found in Section 2.2 Build Alternative Proposed Project. This proposed Negative Declaration (ND) is included to provide notice to interested agencies and the public that it is Caltrans intent to adopt an ND for this Project.

Caltrans has prepared an Initial Study for this Project and pending public review expects to determine from this study that the proposed Project would not have a significant effect on the environment for the following reasons: The proposed Project would have no effect on aesthetics, agriculture and forestry, air quality, cultural resources, energy, geology and soils, hydrology and water quality, land use and planning, mineral resources, population and housing, public services, recreation, tribal cultural resources, utilities and service systems, and wildfire. The proposed Project would have a less than significant impact on greenhouse gas emissions, hazards and hazardous materials, noise, and transportation and traffic. Additionally, the Project would have a less than significant impact on biological resources.
