- Option B would cost between $145 million and $203 million to build a single building with a city hall, justice center, parking garage and plaza.
- Option C would cost between $155 million and $216 million for two buildings housing the city hall, justice center, parking garage and plaza.
- Option D would cost between $85 million and $119 million to only build the city hall, parking garage and plaza.
The city of SeaTac, Washington, is moving forward with the creation of a new civic campus, with an estimated cost between $85 million and $216 million to build a city hall and supporting amenities. Currently in the design phase, construction is slated to begin in late 2027.
Working off a feasibility report, the SeaTac City Council determined that the initial pitch to renovate and expand the existing city hall would be cost-prohibitive without resolving core issues plaguing the building.
The current structure is severely outdated, lacking adequate seismic safety measures, systems that have lived past their useful life, fail to accommodate ADA individuals, missing needed space and containing several hazardous materials.
Officials are considering three alternatives for the civic campus, located at a site the city council plans to secure this December.
