The King County Archives holds original and reproduction drawings of many former and existing county structures. Degree of detail may vary (full architectural or structural drawings, elevations, sections and detail drawings; or just simple site plans or outline sketches). Some structures represented in these collections are: Boeing Field structures; bridges; county maintenance shops and other facilities; health and social services facilities; hospitals; juvenile detention facilities; King County Administration Building; King County Courthouse (formerly, County-City Building); the Kingdome stadium; park and recreational structures; sand and gravel bunkers; warehouses; and wharves, docks, and ferry passenger waiting rooms and shelters.

A small number of drawings of non-county structures, acquired by county agencies, can also be found in these collections.

Please contact the Archives with questions, or to schedule a viewing appointment.
