10-1T730-Culvert Replacement

The California Department of Transportation District 10 in Stockton is forecasting a project to replace three damaged and failing culverts on State Route 49 in Mariposa County. The work is located at postmiles 12.50, 12.55, and 12.79 and will be performed entirely within existing Caltrans Right of Way. The project involves installing reinforced concrete pipes and associated structures to ensure motorist safety over these drainages. This effort is classified under NAICS code 237310. The project has been granted a Categorical Exemption under CEQA Class 1 and qualifies for NEPA categorical exclusion under 23 USC 326 and 327, as no significant environmental impacts are anticipated. The project documentation confirms there are no expected impacts on sensitive species, cultural, or scenic resources. Environmental commitments include specific provisions for cultural resource protection, hazardous waste management, and biological survey requirements. The project was certified and processed in July 2026.
