About SeaTac, WA

SeaTac is a city in southern King County, Washington, United States. The city is an inner-ring suburb of Seattle and part of the Seattle metropolitan area. The name "SeaTac" is derived from the Seattle–Tacoma International Airport, itself a portmanteau of Seattle and Tacoma. The city of SeaTac is 10 square miles (26 km2) in area and has a population of 31,454 according to the 2020 census. The city boundaries surround the Seattle–Tacoma International Airport (approximately 3 square miles (7.8 km2) in area), which is owned and operated by the Port of Seattle. The city includes the communities of Angle Lake, Bow Lake, McMicken Heights and Riverton Heights, which were established before the city's incorporation. Residents voted for incorporation on March 14, 1989, and the city incorporated in February 1990. == 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 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.
