Strengthening tsunami maritime response and mitigation through inclusive stakeholder engagement: Lessons learned in Washington State

Among the most vulnerable facilities to tsunami impacts are ports, harbours and marinas. The ability of maritime infrastructure to withstand a disaster and resume operations quickly plays a major factor in the recovery of the local community and economy in the short and long term. Despite this, little established guidance exists to assist the maritime community with addressing their tsunami risk in an actionable, site-specific manner. To close this gap and improve the resilience of its maritime community, Washington State has begun developing tsunami maritime response and mitigation strategies for major ports, harbours and marinas along its 3,200 miles of coastline. These strategies include detailed information about the location's specific tsunami risk, recommended guidance for vessel operators in the area, and tsunami mitigation and response recommendations ranked by their implementation feasibility for the maritime entity in question. Most importantly, the strategies are created through close collaboration with local key stakeholders, subject matter experts, local emergency management and state agencies to ensure a final deliverable that is accurate, thorough and, above all, useful to the local maritime entity and its tenants and users. As this paper will discuss, the lessons learned during the planning and delivery of these strategies provide valuable insight for professionals in the maritime, business continuity and emergency management fields, including how to conduct effective and inclusive stakeholder engagement, identify gaps and opportunities in resilience planning, and establish a deeper understanding of tsunami maritime risk and hazards.
