History

The Highline area, which includes modern-day SeaTac, Burien, most of Des Moines, and unincorporated communities such as White Center and Boulevard Park, was settled by European Americans in the mid-1850s. The federal government finished construction of a military road from Fort Steilacoom to Fort Bellingham in 1860, passing through the Highline area to the east of modern-day SeaTac. One of the more prominent roads of travel from Seattle to Tacoma early in the 20th century is Des Moines Memorial Drive (originally called the High Line road), which passes directly through the middle of the region, particularly through SeaTac and Burien especially.

Incorporating the area as a city was proposed by local residents in the 1980s, while a competing proposal sought annexation into Des Moines or another city. Local residents voted for incorporation on March 14, 1989, and the city incorporated on February 28, 1990. Des Moines amended their annexation territory following the decision. The original ballot used the name “Sea-Tac”, but the incorporation petition to the county government omitted the hyphen. In 2014, Gavin Kelly of The Resolution Foundation wrote that “A generation ago SeaTac was what Americans would call a middle-class town. A jet-fueller or baggage handler could earn a decent living.”
