COLUMBIAMEMORIAL.ORG Late Summer 2025 3 Exploring the safety measures Phase I of the expansion is set to be completed in 2027. The resiliency measures included in the design go beyond regulation requirements and will allow the hospital to provide vital services to the Astoria community in case of an earthquake or tsunami. Those measures include: ● Strengthened foundations to survive earthquake-induced liquefaction and tsunami-induced scouring effects. ● All critical patient care spaces and support systems elevated above the extreme event site-specific inundation zone. ● A tsunami-safe refuge space that can accommodate up to 1,898 people in the aftermath of a Cascadia event. ● An external, vertical staircase to allow evacuation to the safe refuge space from the surrounding community. ● A helipad, located on the roof of the structure, to facilitate posttsunami evacuation and supply delivery. ● Additional storage for food, water and supplies to support people seeking refuge prior to evacuation. ● An elevated Emergency Operations Center to maintain communication with the region and response teams during an event. ● Elevated electrical generators, with mechanical, electrical and plumbing systems hardened for patient support and maintained through the intended refuge period. Expanding needed services The expansion will include total new construction of approximately 180,000 square feet, incorporating a critically needed expansion of the Emergency Department. Other expanded areas include additional operating rooms, advanced imaging equipment, additional and larger patient rooms, and expanded lab services. The expansion will help CMH continue to grow, bringing new services and state-of-the-art technology and equipment to the community, including robotic surgery.
