SON-101 Guardrail Installation (EA 3X750)

Caltrans, District 4 - Bay Area/Oakland, is forecasting the installation of the Midwest Guardrail System (MGS) along US-101 at San Antonio Avenue in Petaluma, California, from post mile R0.20 to R0.40. The project aims to enhance roadway safety by providing a continuous barrier that connects to existing guardrail infrastructure and includes proper end treatment at the approach end. All construction activities will remain strictly within Caltrans right-of-way, with work staged in areas free of vegetation or designated parking zones to minimize environmental disruption. The project is scheduled for construction in June 2026 and is categorized under a Class 1(c) Categorical Exemption under CEQA/NEPA, indicating it qualifies as an action involving existing facilities without significant environmental impact. The lead agency contact is Juliane Smith, Senior Environmental Scientist, who serves as the primary point of communication, though no formal contracting officer, COR, COTR, or PCO roles are designated in the documentation. No contract value, pricing details, payment office, invoicing instructions, or accounting codes such as TAS or AAC are provided, as this is a forecast notice rather than a solicitation or award document. There are no stated delivery terms, FOB conditions, or contract clauses from FAR or DFARS, and no offeror representations, socioeconomic certifications, or UEI/CAGE codes are included, as the documentation pertains solely to Caltrans’ internal environmental compliance process. The only required submissions are a Notice of Exemption and a certified document of exemption finding, to be mailed to the Office of Planning and Research in Sacramento, with no formal deadline or electronic submission portal specified.
