US Highway 101 Coastal Hazard Vulnerability and Risk Assessment for Mitigation Prioritization

The main objective of this research is to identify and prioritize sites along Highway 101 for possible mitigation. Specific objectives include: (1) Develop erosion rate model(s) with uncertainty estimates; (2) Develop methodology for hazard vulnerability assessment; (3) Develop Oregon Department of Transportation (ODOT) Highway 101 site prioritizations and adaptation options; (4) Deliver planning level geographic information systems (GIS) maps for distribution to ODOT stakeholders; and (5) Deliver Final Report and Research Rollout sessions to ODOT stakeholders. This research will enable ODOT to be proactive in managing coastal risks to infrastructure, directly informing potential Goal 16 and 18 revisions. Conducting this research now also ensures that ODOT is the lead agency assessing risks and priorities for US 101. Without this research, ODOT will remain in a passive and reactive position regarding the mitigation restrictions of Goal 18, while erosion and sea level rise will continue to threaten the safety and reliability of the iconic coastal highway. This research will provide valuable “pre-work” for future regulatory approvals for infrastructure protection, and strategic planning for short and longer-term adaptation options. This research will also help build a common understanding of risks and needs pertaining to the management of coastal hazards across ODOT and will help build partnerships amongst federal, state, and local stakeholders. Additionally, this research addresses infrastructure resilience and reliability under changing climate conditions with an adaptation framework that helps ensure a safe and reliable transportation system for the traveling public.
