Abstract:
The City of Newport (City) plans to develop a tsunami evacuation site to serve the
South Beach area. The proposed site consists of an undeveloped hill located
adjacent to Highway 101, southwest of the Yaquina Bay Bridge (Figure 1A,
Appendix A). The site will be designated Safe Haven Hill. This report addresses the design, construction and survivability of the tsunami
evacuation site. The study focuses on subduction zone earthquake sources capable
of generating a tsunami. Crustal earthquake sources were not considered.
Therefore, the study includes certain elements, but is not intended to meet all the
requirements of a site-specific seismic hazard study per the Oregon Structural
Specialty Code.
