Project Analytical Approach <br />This project's proposed analytical approach will consist of onsite data collection at identified <br />airports/airfields and post -visit analysis to evaluate their resilience to a CSZ earthquake in the context of <br />post -disaster response logistics. The assessment methodology outlined below mirrors a similar <br />methodology that is currently being employed in the 2018 Oregon Transportation RRAP project. <br />The first phase of the project will include airport/airfield site visits for facilitated data collection. <br />Activities during these visits will include: <br />A streamlined facilitated discussion with airport managers, engineers, maintenance personnel, and other <br />airport staff focused on three critical areas: <br />1. Airport infrastructure and facility vulnerability to a CSZ earthquake, including prior studies, design <br />standards, planned capital improvements; and also the exposure of airport infrastructure to primary and <br />secondary seismic impacts (e.g., ground motion, ground failure, tsunami inundation); <br />2. Airport lifeline infrastructure dependencies, including the airport's reliance on external fuel, electricity, <br />telecommunication/data, water/wastewater, and transportation systems; and <br />3. Airport operational considerations and coordination, including exploring the operability of the airport <br />under disrupted conditions, minimum operations, and coordination with federal/regional response efforts <br />A site tour of the airport to examine physical infrastructure, identify response resources and equipment, and <br />observe physical connections to external infrastructure systems <br />Coordination with U.S. Transportation Command (USTRANSCOM) to understand its capabilities and <br />requirements to operate at the airfields visited and to support disaster logistics response efforts <br />The second phase of the project will involve synthesizing findings from the site visits into a report that <br />identifies overarching systemic vulnerabilities, facility -specific seismic vulnerabilities, and resilience <br />enhancement actions that could better enable airports/airfields to support post-CSZ response activities. <br />Project Outcomes <br />The study output would be a project report that synthesizes the information collected and related <br />analysis to improve the state's understanding of how a CSZ earthquake would affect the performance of <br />critical airports/airfields in supporting post -disaster logistics. This information will be valuable for <br />ongoing disaster and investment planning and will identify specific additional knowledge gaps or <br />vulnerabilities that may merit more focused, engineering -based studies of specific facilities. <br />The study will also identify several potential actions that stakeholders could take to improve seismic <br />resilience at major airport/airfield facilities and the linkages to critical lifeline infrastructure systems <br />upon which those facilities rely. In addition, USTRANSCOM will use this information to update its <br />inventory of U.S. airports/airfields (e.g., runway conditions, NAVAIDs/lighting, aircraft weight limits). <br />This information will also inform Defense Support to Civil Authorities (DSCA) planning efforts. <br />
