US 89 post-wildfire flood resiliency project

The County of Coconino received a $1.23 million Project Grant award from the Federal Highway Administration (FHWA) under the Highway Planning and Construction program (CFDA 20.205) on September 25, 2025. The grant supports the US 89 Post-Wildfire Flood Resiliency Project, which addresses transportation infrastructure resilience and flood mitigation challenges on US Route 89 in Arizona resulting from wildfire impacts. The project is scheduled for completion by October 31, 2029, allowing approximately four years for design, planning, environmental compliance, and construction activities.

Under this Highway Planning and Construction award, the County of Coconino will develop and implement flood resiliency improvements to protect critical transportation corridors from post-wildfire flooding hazards. The project aligns with the FHWA's priorities for highway safety improvements and infrastructure resilience by addressing the heightened flood risks that occur in wildfire-affected watersheds. The funding supports eligible activities including engineering analysis, environmental review, design development, and construction of mitigation measures such as drainage improvements, erosion control, and flood-resistant roadway modifications to ensure the continued functionality and safety of US 89 for regional transportation and emergency access.
