Loyalton Culvert Rehabilitation North, EA 03-3G790, EFIS 0325000126

The project involves rehabilitating nine deteriorated culverts along State Route 49 from post mile 61.85 to 64.05 in Loyalton, California, under Caltrans District 3, with the goal of restoring proper drainage while maintaining existing right-of-way boundaries. Work includes removing failed culverts and replacing them with reinforced concrete pipe or corrugated steel pipe of the same or larger diameter, installing flared end sections at all inlets and outlets, replacing rock slope protection where needed, and excavating roadside ditches. All construction is restricted to the non-rainy season between May and October to minimize environmental disruption and is classified as a categorical exclusion under both NEPA and CEQA, requiring no significant environmental review beyond compliance with existing permits and protocols. The project is subject to multiple environmental regulations including the California Department of Fish and Wildlife’s 1600 Agreement, the Regional Water Quality Control Board’s Section 401 Certification, and the US Army Corps of Engineers’ Nationwide Permit 404 Non-Reporting. Adherence to Caltrans Standard Specifications 14-2, 14-7.03, and 14-8-02 is mandatory for archaeological, paleontological, and noise control requirements. Performance is limited to the project site, with inspections and acceptance conducted on-site by Caltrans personnel, including the Project Manager, Senior Environmental Planner, and Associate Environmental Planner as key oversight contacts. While the contract’s structure follows Caltrans procedural formats including a PS&E Package and Environmental Commitments Record, it lacks formal contract type designation, pricing data, line items, evaluation factors, or specific delivery timelines beyond the seasonal work window. No contractor is named, and no solicitation number or contract value is provided, suggesting this is a pre-solicitation forecast or planning document. Electronic submissions via a Caltrans digital portal are required, with documents signed electronically and tracked through audit trails. All environmental and regulatory obligations are the responsibility of the lead agency, with no offeror certifications or socioeconomic representations included in the documentation.
