SeaTac (/ˈsiːtæk/) is a city in southern King County, Washington, United States.

[5] 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.

[8] 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.

[9] 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.

The original ballot used the name "Sea-Tac", but the incorporation petition to the county government omitted the hyphen.

[11] In 2014, Gavin Kelly of The Resolution Foundation wrote that "A generation ago SeaTac was what Americans would call a middle-class town.

"[12] 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.

There are currently 51 patrol officers, detectives, and support staff assigned full-time to the city.

The judge is authorized by the Revised Code of Washington to preside over civil infractions, traffic infractions, criminal misdemeanor and gross misdemeanor violations, and civil orders for protection.

[19] Public Works is responsible for planning, design, construction and maintenance of streets, transportation improvements, surface water utility, and solid waste and recycling programs.

[20] 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.

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.

[23] The National Transportation Safety Board operates the Seattle Aviation Field Office in the city.

They employ nearly 40,000 employees in the city of SeaTac and generate local sales of approximately $3.7 billion.

The new department has four divisions: Economic Development, Planning, Engineering Review, and Building Services.

The most commonly spoken foreign languages in SeaTac are, in order, Spanish, Somali, and Punjabi.

[57] With the opening of Glacier Middle School in north SeaTac, residents north of the airport are generally zoned there and subsequently to Highline High School given the proximity of that area to Burien.

[64] The 2.5-acre (10,000 m2)[65] McMicken Heights Park has an open area, playground equipment, and tennis courts.

[64] The 165-acre (0.67 km2)[65] North SeaTac Park has the SeaTac Community Center, baseball, soccer (football), and softball fields, a disk golf course, an outdoor basketball court, an open area, playground equipment, a picnic shelter, toilet facilities, BMX track and paved walking trails.

[67] The city is also served by several public transportation services: Link light rail stops at two stations in the city, at SeaTac/Airport station and Angle Lake station; King County Metro operates several bus routes in the area, including the RapidRide A Line on International Boulevard and RapidRide F Line on Southcenter Boulevard;[68][69] some Sound Transit Express regional bus routes terminate or serve the SeaTac area, primarily the airport and other transit hubs.
