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

The Loyalton Culvert Rehabilitation North project, identified by EA 03-3G790 and EFIS 0325000126, is a forecast effort by the California Department of Transportation District 3 to repair failed culverts on State Route 49 in Sierra County. The scope of work involves the rehabilitation of nine culverts between post miles 61.85 and 64.05, including the removal of existing structures and their replacement with culverts of the same or larger diameters, such as 24 inch reinforced concrete pipes. Additional requirements include the installation of flared end sections, replacement of rock slope protection, and the excavation of roadside ditches. All activities will be performed within the Caltrans right-of-way. The project is categorized as a repair and maintenance effort and is exempt under CEQA Class 1 and NEPA categorical exclusion. Environmental commitments require permits from the US Army Corps of Engineers, the Regional Water Quality Control Board, and the California Department of Fish and Wildlife. Work is scheduled to occur between May and October to align with the non-rainy season. Contractors must adhere to specific Caltrans Standard Specifications regarding noise control, archaeological resources, and the discovery of unanticipated paleontological resources. Project administration is led by Project Manager Girmay Beyene and Environmental Planner Obaida Akther.
