# SeaTac, Washington

SeaTac (/ˈsiːtæk/) 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 Seattle–Tacoma International Airport, itself a portmanteau of Seattle and Tacoma.
The city of SeaTac is 10 square miles (26 km$^2$) 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 km$^2$) 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 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.
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."

### Local government

Presidential Elections Results :
| Year | Republican | Democratic | Third Parties |
| 2020 | 28.17% 3,229 | 69.12% 7,924 | 2.71% 311 |

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." Deputies assigned to SeaTac wear city uniforms and drive patrol cars marked with the city logo. There are currently 51 patrol officers, detectives, and support staff assigned full-time to the city.
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. SeaTac's three fire stations, Station 45, 46, and 47, joined Kent's Station 73 to make up RFA's West Battalion.
The Seatac Municipal Court, located in the City Hall, is a court of limited jurisdiction. 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.
Public Works is responsible for planning, design, construction and maintenance of streets, transportation improvements, surface water utility, and solid waste and recycling programs.
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. Union workshops are exempt from the $15 minimum wage. 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.

### Federal government presence

The Riverton Heights Post Office is located in the city.
The National Transportation Safety Board operates the Seattle Aviation Field Office in the city.
The Federal Bureau of Prisons operates the Federal Detention Center, SeaTac in SeaTac.

## Economy

The city is home to over 900 licensed businesses, nearly 80 of which are Fortune 1000 companies. They employ nearly 40,000 employees in the city of SeaTac and generate local sales of approximately $3.7 billion.
Alaska Airlines and Horizon Air are headquartered in the city. Four airlines have operations at 18000 Pacific Highway South (also known as 18000 International Boulevard) in the city, including Asiana Airlines, EVA Air, Hainan Airlines, and China Airlines.

### Economic development

SeaTac's Department of Community and Economic Development was formed in early 2011 to create a one-stop permitting center, increase the level of service and assist in the facilitation of economic development by creating a more cohesive approach to real estate development and job creation. The new department has four divisions: Economic Development, Planning, Engineering Review, and Building Services. In 2013, the City of SeaTac Proposition No. 1 passed with 50.64% of the vote to raise the minimum wage to $15 per hour.
