Repair Storm Damage

An emergency repair project is scheduled along State Route 299 at Post Mile 13.96 in Humboldt County, California, to address severe damage caused by heavy winter rains during 2025/2026. The prolonged saturation of soils led to erosion, earth movement, and the disconnection of a downdrain from the cross culvert, which resulted in significant bank and slope degradation and the undermining of the embankment supporting the roadway. This condition poses an immediate threat to the integrity of the traveled way and presents a safety hazard to the public. The project aims to stabilize the compromised slope, restore the drainage system, and reinforce the roadway structure to prevent further deterioration and ensure long-term functionality. The contract, titled Repair Storm Damage and posted by Caltrans District 1 - Eureka on July 15, 2026, is designated as a forecast and is being managed with urgency due to the critical nature of the infrastructure failure. The work will focus on reinstating the hydraulic connectivity of the drainage system, repairing or replacing the failed downdrain and culvert components, and reconstructing the eroded fill prism and embankment to support the roadbed. Jeffrey Jahn, Environmental Coordinator, serves as the primary point of contact for inquiries and can be reached via phone or email. The project’s location and scope underscore the need for timely intervention to safeguard public safety and maintain critical transportation infrastructure in a region prone to severe weather events.
