SR-128 Slurry Seal Project (EA 2X780)

Caltrans is planning to perform a slurry seal treatment on 15.2 miles of State Route 128 in Napa County, extending from post mile 19.1 to 34.3, with the objective of preventing further pavement deterioration and extending the roadway’s service life. All work must occur within the existing roadway prism and Caltrans right-of-way, with equipment staged only in vegetated-free areas and no activity permitted in or near water bodies. Construction is scheduled to begin no earlier than August 1, 2026, and must be completed by October 15, 2026. Damaged or removed pavement markings and delineation will be restored as part of the project. The project has been categorized under CEQA Class 1(d) exemption (14 CCR 15301), indicating it qualifies as an improvement to an existing facility with no significant environmental impact, and supporting documentation includes a certified exemption finding and a Notice of Exemption. The contract is listed as a forecast with no formal solicitation number, contract value, pricing details, or awarded contractor identified. Caltrans District 4 in Oakland is the lead agency, with Juliane Smith, Senior Environmental Scientist, serving as the primary point of contact for environmental compliance matters. No formal contract clauses from FAR, evaluation factors, payment or invoicing instructions, accounting codes, or special requirements such as COR/COTR designation or size status certifications are provided in the available documentation. No FOB terms, packaging requirements, or submission guidelines for proposals are included, and the procurement process has not progressed beyond the planning and environmental exemption stage.
