HWY-1 Slope Erosion Repair DO (EA 4X500)

Caltrans is undertaking an emergency repair project on Highway 1 in San Mateo County, specifically along the east side shoulder between post miles 36.06 and 36.12, to address a 1,100-square-foot area of slope erosion triggered by storm damage and the failure of a drainage ditch. The erosion has undermined the structural integrity of the slope, endangered existing vegetation, and created a risk of complete slope failure that could disrupt Highway 1—a high-traffic route—and threaten nearby private residences. The work will stabilize the slope through the installation of rock slope protection and implement landscape erosion control measures to prevent future degradation, with temporary traffic control measures required throughout construction to ensure public safety and maintain highway operations. The project is being executed under a CEQA categorical exemption, Class 1(d), indicating it qualifies as a minor repair using standard Caltrans practices with no significant environmental impact. The solicitation number for the project is EA 4X500, and while the contract is designated as a “DO,” the specific contract type, pricing structure, or detailed cost information is not provided in the available documentation. No formal FAR clauses, evaluation factors, award methodology, payment details, or contracting officer representatives are identified. The only designated point of contact is Juliane Smith, Senior Environmental Scientist, who serves as the NEPA/CEQA specialist and is affiliated with Caltrans District 4’s Office of Maintenance Environmental at 111 Grand Ave, Oakland, CA. The project’s place of performance is clearly defined, and no attachments, delivery schedules, or invoicing protocols are specified, reflecting the expedited, environmentally exempt nature of the maintenance action.
