The predicted Magnitude 9.0 or greater earthquake along the Cascadia Subduction Zone (CSZ) has been the single event that dominates the risk to Oregons transportation network: An event of this enormity will result in significant loss of life and the widespread destruction of dwellings, businesses, and public buildings leaving large areas of coastal and western Oregon isolated for a long period of time possibly years. Unfortunately, the effects of Climate Change also pose a similar threat to the system. Extreme weather events associated with climate change wont be as destructive or widespread as a CSZ earthquake in any single event, but will be a recurring issue with a similar cumulative effect. The key to rescue, relief, and recovery after such extreme events is a functioning transportation system.
In 2011, the Oregon Legislature directed the Oregon Seismic Safety Policy Advisory Commission to lead the coordination of an Oregon Resilience Plan, presented to the Legislature in 2013. ODOT was a major participant in this effort and later supplemented this work with its own Seismic Options Report, which provides more focus on the effects of a major seismic event on Oregons surface transportation system. In this latter effort, ODOT identifies critical Lifeline Routes which will serve as the backbone of the transportation system to allow delivery of critical resources after the event. Route selection to prioritize resources takes three main principles into account: Survivability, Life Support, and Economic Recovery.
ODOT has also recognized the need to assess the vulnerability of the highway system to the effects of a changing climate. To this end, the agency has embarked on several efforts to assess the potential impacts of climate change that include: sea level rise, storm surge, storm frequency and intensity, and increased wave height. This work has included a pilot study on coastal highway vulnerability and ongoing research projects that are evaluating climate effects on coastal bluff erosion, landslide acceleration, and the economic impacts of weather-related events on the highway system. These efforts will inform future agency policy with respect to climate change adaptation.
