Historical government building plans

This series consists of maps, plans and other graphical materials that visually represent the infrastructure of the King County International Airport (Boeing Field) from the time of its construction (1929) to 1999. They were brought together as a group by the King County Department of Transportation in 2002 in response to potential litigation involving the cleanup of the Duwamish River. As part of this process the record items were professionally conserved and digitized.

Types of graphical material in this series include: master site and layout plans , including maps showing utilization of Boeing Field by the United States military during World War II; maps of owned and leased airport property, including maps of specific property acquisitions and demolitions; utility maps (air, electrical, fire systems, lights, plumbing); sanitary and storm sewers, storm drains and pump stations; plans of structures of the King County International Airport (passenger facilities, hangars, ancillary structures, airport lessees' structures); plans of Boeing Company structures located at the airport; maps of fuel tank locations; environmental inventories and maps and plans relating to water pollution control programs.

These architectural records were collected and maintained by the Department of Stadium Administration's Maintenance Section. Documenting the Kingdome as a physical structure, one that was a subject of controversy and litigation later in its life, the records consist of project and subject files, and plans and drawings. Major topics represented include baseball field expansion; ceiling repair; consultant reports; documents relating to original Kingdome construction (construction specifications and other documents, mylar drawings of design and structure); executive suite design and construction; landscaping; maintenance office and shop expansion; miscellaneous studies; modifications for executive suites and roof renovation; pre-Kingdome stadium proposals; and specific project files (concession areas, day care facility, railing caps, seating additions, sprinkler system).

King County Archives holds original records created by the King County Road Services Division and its predecessors. These records include aerial photographs; historical survey data; building plans; and a variety of specialized maps (assessor, bridge, drainage, engineering, erosion control, establishment, maintenance, parks, right-of-way, roads, structure, survey, topographical and traffic). They also contain supporting documentation about the establishment, construction and maintenance of county roads and bridges, and of other county structures and facilities which are, or have been, the responsibility of the division or its functional predecessors.

King County Road Services Division maintains digitized copies of the originals held by the Archives, and makes them available online on the Map Vault. The King County Road Services Division's Map and Records Center also retains physical custody of some of the older supporting documentation relating to county roads. Digitized records available on the Map Vault include:

• Boeing Field structures
• Bridges
• County maintenance shops and other facilities
• Health and social services facilities at Georgetown, south Seattle (indigent shelter, tuberculosis hospital, crematorium)
• Hospitals
• Juvenile detention facilities
• Park and recreational structures
• Sand and gravel bunkers
• Schools
• Wharves, docks, and ferry passenger waiting rooms and shelters
