'''SeaTac''' ({{IPAc-en|ˈ|s|iː|t|æ|k}}) is a city in southern [[King County, Washington]], United States. The city is an [[Inner suburb|inner-ring]] [[suburb]] of [[Seattle]] and part of the [[Seattle metropolitan area]]. The name "SeaTac" is derived from [[Seattle–Tacoma International Airport]], itself a portmanteau of Seattle and [[Tacoma, Washington|Tacoma]].

The city of SeaTac is {{convert|10|mi2|km2|0}} in area and has a population of 31,454 according to the [[2020 United States census|2020 census]].<ref name="2020 Census (City)">{{cite web|title=Explore Census Data |url=https://data.census.gov/profile/SeaTac_city,_Washington?g=160XX00US5362288 |publisher=[[United States Census Bureau]] |access-date=February 20, 2024}}</ref> The city boundaries surround the Seattle–Tacoma International Airport (approximately {{convert|3|mi2|km2|1}} in area), which is owned and operated by the [[Port of Seattle]]. The city includes the communities of [[Angle Lake, Washington|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,<ref name="SeaTacHistory">{{cite web|title=SeaTac History |url=http://www.historylink.org/index.cfm?DisplayPage=output.cfm&file_id=4181 |publisher=[[History Link]] |access-date=December 30, 2014}}</ref> and the city incorporated in February 1990.<ref name=welcome>{{cite web|url=https://www.seatacwa.gov |title=Welcome to the City of SeaTac 'The Hospitality City' |publisher=City of SeaTac |access-date=December 30, 2014}}</ref>

==History==
{{expand section|date=February 2014}}

The Highline area, which includes modern-day SeaTac, [[Burien, Washington|Burien]], most of [[Des Moines, Washington|Des Moines]], and unincorporated communities such as [[White Center, Washington|White Center]] and [[Boulevard Park, Washington|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.<ref>{{cite web |last1=Dorpat |first1=Paul |author-link1=Paul Dorpat |last2=Crowley |first2=Walt |author-link2=Walt Crowley |date=May 31, 2003 |title=SeaTac — Thumbnail History |url=http://www.historylink.org/File/4181 |work=[[HistoryLink]] |access-date=February 17, 2018}}</ref> 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.

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.<ref>{{cite news |last=Godchaux |first=Erik |date=December 9, 1987 |title=Sea-Tac area eyes cityhood |page=B1 |work=The News Tribune |url=https://www.newspapers.com/clip/98617264/sea-tac-area-eyes-cityhood/ |via=Newspapers.com |access-date=March 28, 2022}}</ref> 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.<ref>{{cite web |last=Wilma |first=David |date=March 15, 2006 |title=City of SeaTac incorporates on February 28, 1990. |url=http://historylink.org/File/7689 |work=HistoryLink |access-date=February 17, 2018}}</ref> 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."<ref name=KellyGavinSmallt>Kelly, Gavin.

SeaTac is governed by a city council which consists of seven elected councilpersons. The city "has contracted with the [[King County Sheriff's Office]] for law enforcement since incorporation in 1990."<ref>{{cite web|title=King County Sheriff |url=http://www.kingcounty.gov/safety/sheriff/our-communities/SeaTac.aspx |publisher=King County |access-date=December 30, 2014}}</ref> Deputies assigned to SeaTac wear city uniforms and drive patrol cars marked with the city logo.

In January 2014 the SeaTac Fire Department entered a 20-year contract with Kent Fire Department Regional Fire Authority (RFA) to form the [[Puget Sound Regional Fire Authority]].<ref>{{cite web|title=SeaTac Fire joins Kent Fire RFA |url=http://www.ci.seatac.wa.us/index.aspx?page=682 |publisher=City of SeaTac |access-date=December 30, 2014}}</ref><ref>{{cite web|title=History |url=http://kentfirerfa.org/index.aspx?nid=93 |publisher=Kent, WA Fire Department Regional Fire Authority |access-date=December 30, 2014}}</ref> SeaTac's three fire stations, Station 45, 46, and 47, joined Kent's Station 73 to make up RFA's West Battalion.<ref>{{cite web|title=Stations & Facilities |url=http://www.kentfirerfa.org/index.aspx?nid=184 |publisher=Kent, WA Fire Department Regional Fire Authority |access-date=December 30, 2014}}</ref>

In 2013, voters in the city narrowly passed a minimum wage of $15 per hour for employees of airport-related businesses, such as hotels, parking lots and car rental agencies. In a later appeals court decision, the $15 minimum wage was reversed for employees working entirely on Port of Seattle property within the city limits but still applies to employees of airport-related businesses in the city proper.<ref name=KellyGavinSmallt/> Union workshops are exempt from the $15 minimum wage.<ref>[https://www.washingtonpost.com/opinions/dana-milbank-no-calamity-yet-as-seatac-wash-adjusts-to-15-minimum-wage/2014/09/05/d12ba922-3503-11e4-9e92-0899b306bbea_story.html Raising the minimum wage without raising havoc], Washington Post, September 5, 2014</ref> However, the Washington Supreme Court in August 2015 reversed the King County Superior Court ruling, which said that SeaTac did not have authority to set a minimum wage at the airport. The Supreme Court rejected the argument that the wage did not apply because the airport is owned by the Port of Seattle. The Court stated that Proposition 1 can be enforced at Seattle–Tacoma International Airport because there is no indication that it will interfere with airport operations and that federal labor law does not preempt the provision protecting workers from retaliation.<ref>{{cite web|url=http://blog.seattlepi.com/seattlepolitics/2015/08/20/state-supreme-court-rules-sea-tacs-15-an-hour-minimum-wage-applies-to-airport-workers/|title=State Supreme Court rules: Sea-Tac's $15-an-hour minimum wage applies to airport workers|date=August 20, 2015|website=seattlepi.com}}</ref>
