10-1V020-E. Fork Chowchilla River Damage

The project addresses emergency repairs to the E. Fork Chowchilla River bridge near State Route 49 in Mariposa County, California, where slope erosion and washout onto Kemble Road have occurred due to a collapsed drainage pipe and damaged asphalt concrete dike that no longer effectively directs runoff to the inlet box. Work involves removing eroded and unsuitable material from embankments, backfilling with suitable material to restore stability, injecting cement slurry into voids, replacing the damaged drainage pipe, reconstructing the AC dike, and implementing permanent erosion controls on disturbed soils—all within Caltrans Right of Way. The project is classified as an emergency repair under Caltrans’ Director’s Order program, with environmental compliance driven by CEQA and NEPA categorical exclusions pursuant to 23 USC 326 and 327, and 23 CFR 771.117. It is managed by Caltrans, District 10 – Stockton, with project oversight led by the Senior Environmental Planner and Project Manager. The place of performance is clearly defined at Post Mile 3.0 off SR-49, and acceptance is expected to occur on-site. Special requirements include strict environmental protections: all work must halt immediately upon discovery of cultural resources or human remains, with mandatory notification of the County Coroner, qualified archaeologists, the Native American Heritage Commission, and the Most Likely Descendant group under PRC §5097.98. Any scope change triggers a formal environmental reevaluation. No contract value, pricing detail, award basis, or formal solicitation number is listed, indicating this is a forecasted effort still progressing through internal environmental approvals. The posting date is January 28, 2026, with environmental documentation finalized in late January 2026, suggesting imminent procurement. There is no information on contract type, payment offices, invoicing systems, inspection standards beyond regulatory compliance, packaging requirements, or evaluation factors, and no offeror representations or certifications are included, reflecting the preliminary and environmentally focused nature of this emergency repair initiative.
