Cascadia Event Risk Assessment and Community Evacuation
The City Council meeting commenced with a presentation from Dugamey on the risk assessment and hazards of community evacuation during a Cascadia event in Cannon Beach. Jonathan Allen, a Ph.D. geologist with the Oregon Department of Geology and Mineral Industries, and Laura Gable, a registered geologist with Dugamey, led the discussion. They emphasized the importance of improving survivability during a tsunami event through enhancements to First Street and the construction of vertical evacuation structures. Their findings were based on extensive research, including the "Beat the Wave" studies, which provided technical insights into tsunami inundation and evacuation strategies.
The presentation highlighted the need for seismic improvements to the First Street Bridge, which could significantly increase survivability rates. The city had already secured a $480,000 hazard mitigation grant to study these improvements. The discussion also touched on the potential for vertical evacuation structures, which have been successfully implemented in other areas such as Seaside and Westport, Washington.
