SR-221 Cold Plane and RHMA-G (EA 04-4X980)

Caltrans District 4 is proposing a pavement rehabilitation project on State Route 221 in Napa County, specifically from post mile 1.7 to 2.7. The scope of work involves cold planing existing asphalt concrete pavement and repaving it with rubberized hot mix asphalt gap graded to prevent further deterioration of the highway. All construction activities are restricted to the paved roadway prism within the Caltrans right of way and will utilize equipment such as AC trucks, grinders, loaders, pavers, and rollers. This project, identified as EA 04-4X980, is classified as a forecast and has been granted a CEQA categorical exemption under PRC 21084 and 14 CCR 15301 Class 1 for existing facilities. The project is managed by Caltrans in the Bay Area/Oakland region, with Juliane Smith serving as the primary point of contact. The official notice of exemption was signed on August 26, 2026, with the project posting date listed as August 27, 2026.
