DO Emergency MPA HWY 140 Rockslide

The California Department of Transportation, District 10, is implementing the DO Emergency MPA HWY 140 Rockslide project in Mariposa County under solicitation number 10-1U450. The project focuses on emergency repairs and mitigation on State Route 140, specifically from Postmiles 39.0 to 41.5 and 42.6 to 43.0. The scope of work includes scaling rockwalls to prevent future slides, removing existing rockslide materials, and repairing damaged pavement. These actions are deemed necessary to prevent and mitigate the loss or impairment of life, property, and essential public services. The project is classified as a forecast with NAICS code 237310 and has been granted a CEQA exemption and NEPA categorical exclusion, as no significant environmental impacts are anticipated and no permits are required. Key administrative contacts include Project Manager Scott Uch and Environmental Scientist Maria Garcia Lopez. Special contract requirements mandate strict protocols for the discovery of cultural materials or human remains, requiring an immediate work stoppage within a 60-foot radius and notification of the Engineer or County coroner. Additionally, any changes to the project scope or discovery of sensitive resources will trigger a mandatory environmental reevaluation.
