"he objective of this study is to provide local government with a quantitative assessment of the difficulty of evacuating Seaside and Gearhart for the XXL1 and L1 scenarios in order to evaluate mitigation options such as evacuation route improvement, better wayfinding, land use planning actions, and implementation of vertical evacuation. We achieve the objective by 1) using the least cost distance (LCD) approach of Wood and Schmidtlein (2012) to provide estimates of walking times to safety, here defined as 20 feet beyond the inundation zone, for every place of origin in the community, 2) illustrating how quickly the wave front of an L1 or XXL1 tsunami advances across the area after the causative earthquake, and 3) determining whether an evacuee can stay ahead of the tsunami all the way to safety on the routes defined by the LCD analysis. The latter method is implemented by a new approach termed "beat-the-wave" (BTW) evacuation difficulty analysis that shows minimum speed to stay ahead of the tsunami all the way to safety. We then summarize which parts of each city are most in need of tsunami hazard mitigation"--Page 3. Includes bibliographical references.
