NEV 49 Dual Barrel Culvert Replacement (EA 03-2N080)

The California Department of Transportation (Caltrans), District 3 – Marysville/Sacramento, is undertaking the replacement of a failed dual barrel corrugated metal pipe (CMP) culvert with a reinforced concrete pipe (RCP) dual barrel culvert along State Route 49 at post mile 17.76 in Nevada County. The project scope includes mobilization, removal of the existing CMP, installation of the new RCP system, replacement of both inlet and outlet headwalls, placement of rock slope protection, installation of a temporary water diversion system, shoring, and comprehensive traffic control measures, all confined within existing right-of-way to minimize environmental disruption. The work is classified under a categorical exclusion under both the California Environmental Quality Act (CEQA Class 1(d)) and the National Environmental Policy Act (23 CFR 771.117(c)(1) and (d)(1)), supported by federal authorities 23 USC 326 and 327, and approved under the FHWA-Caltrans MOU of May 27, 2022, with an associated CDFW 1610 exemption for aquatic resource impacts. The project was formally approved and signed by Caltrans personnel on September 29, 2025, via internal environmental documentation rather than a competitive solicitation, with no published contract value, pricing structure, or formal contract type identified. No solicitation number, evaluation factors, or contractor selection criteria were released, indicating the work is being administered as an agency-led repair initiative under existing authority. Key contacts include Jason Ammerman as the environmental scientist lead, Lisa Machado as the senior environmental planner, and Zabi Sakhi as the project manager, who are responsible for coordination and compliance, though no contracting officer, COR, or COTR roles are formally designated. All activities are to be performed on-site with no offsite borrow or disposal required, and no packaging, marking, invoicing, payment, or delivery terms are specified, consistent with the nature of the work being a direct construction and infrastructure replacement effort under exempted environmental review.
