Proactive Strategy For Climate Resilient Corridors: Landslide Hotspot Prioritization, Planning, And Management Tool

Landslides are frequent hazards that affect Oregon highway infrastructure, resulting in negative economic, environmental, and social impacts for Oregon communities. Goals from the Oregon Transportation Plan (OTP) include proactive preparation of lifeline routes to reduce possible hazards before events occur, starting with the strategy to map and assess multi-hazard threats to the transportation system. While Oregon Department of Transportation's (ODOT's) Climate Adaptation and Resilience Roadmap and Climate Hazard Risk Map identify resilience corridors to help prioritize investment, a higher resolution analysis to prioritize between sites along these corridors is needed for development of compelling business cases for investment and competitive funding opportunities. ODOT is already under financial strain reacting to landslide hazards as they happen. Given that these hazards are projected to increase in frequency/magnitude with climate change, reactive approaches for returning to site functionality will exacerbate ODOT’s fiscally constrained reality. High resolution landslide hazard site vulnerability analysis followed by site prioritization will provide planning and management teams practical science-based investment strategies aimed at improving safety, ensuring working emergency lifeline routes, preventing community isolation, and reducing rising maintenance costs for hazard removal.
