The Federal Highway Administration (FHWA) awarded $528,100 to the California Department of Transportation (Caltrans) on September 4, 2025, under the Emergency Relief (ER) Program (CFDA 20.271) to perform washout mitigation measures on State Route 680 in Contra Costa County. The project encompasses debris removal and site stabilization work at the Livorna and El Cerro on-ramps and vicinity slipouts on northbound Route 680 across the cities of Danville, Alamo, and Walnut Creek. Work activities include removal of mud, tree and shrub debris, rock and boulder debris, and other accumulated debris from the affected areas.

The project is scheduled for completion by December 30, 2026. As a federally authorized emergency relief program, the ER Program provides funding to repair and reconstruct Federal-aid highways damaged by natural disasters or catastrophic failures, with FHWA administering permanent annual contract authority of $100 million from the Highway Trust Fund. This award reflects the reactive funding mechanism characteristic of the ER Program, whereby states submit applications within two years of eligible disaster events to address emergency infrastructure repair needs.
