The order requires every municipal department to update its emergency‑response protocols, ensure staff understand their roles during a major incident, and regularly exercise plans that keep essential services running under crisis conditions.

Under the new directive, the Office of Emergency Management (OEM) will lead an interdepartmental training team that includes representatives from the Seattle Police Department, Fire Department, Department of Transportation, Public Utilities, City Light and Human Resources, and will conduct at least two citywide tabletop exercises and one functional exercise in the Emergency Operations Center each year.

The mayor’s order also calls for after‑action reviews after any incident that activates the Emergency Operations Center or involves OEM coordination, with the goal of extracting lessons learned and tightening the city’s overall response capability.

The measure comes nearly two months after the deadly “Bite of Seattle” shooting, an event that exposed gaps in communication and coordination. Newly released police text messages showed confusion over command responsibilities, and the city’s official Alert Seattle system was not activated, prompting criticism that subscribers missed critical warnings.

Mayor Wilson said the Alert Seattle system “could and should have been used” during the shooting, noting that an activated alert could have warned people to avoid the Seattle Center area. OEM Director Curry Mayer confirmed that any department can request an alert, but she could not recall any request being made on the night of the shooting.

Beyond mass‑shooting response, the order addresses a broader slate of threats, citing extreme heat, flooding, wildfires, sea‑level rise, severe storms, earthquakes and other climate‑related hazards as growing risks to public safety, infrastructure and the economy. It also directs the city to plan for large‑scale deployments of federal law‑enforcement or military personnel.
