Arlington is a city in northern Snohomish County, Washington, United States, part of the Seattle metropolitan area. The city lies on the Stillaguamish River in the western foothills of the Cascade Range, adjacent to the city of Marysville. It is approximately 10 miles (16 km) north of Everett, the county seat, and 40 miles (64 km) north of Seattle, the region's largest city. As of the 2010 U.S. census, Arlington has a population of 17,926.
Arlington was established in the 1880s by settlers and the area was platted as two towns, Arlington and Haller City. Haller City was absorbed by the larger Arlington, which was incorporated as a city in 1903. During the Great Depression of the 1930s, the Arlington area became home to projects under the direction of federal relief agencies, including a municipal airport that would serve as a naval air station during World War II. Beginning in the 1980s, Arlington experienced the effects of suburbanization, growing by over 450 percent by 2000 and annexing the unincorporated area of Smokey Point to the southwest.
The economy of the Arlington area historically relied on timber and agriculture, but has since transitioned to a service economy with some aviation industry jobs near the municipal airport. The city is governed by a mayor–council government, electing a mayor and seven city councilmembers. The municipal government also maintains the city's parks system and water and wastewater utilities. Other services, including public utilities, public transportation, and schools are contracted to regional or county-level agencies and companies.
Prior to American exploration and settlement in the 19th century, the Puget Sound region was inhabited by indigenous Coast Salish peoples. The confluence of the two forks of the Stillaguamish River, the location of present-day downtown Arlington, was a prominent campsite for the Stillaguamish and Sauk peoples while following fish runs; the Stillaguamish named the campsite Skabalko, and had a major village at Chuck-Kol-Che upriver near modern-day Trafton.
American exploration of the area began in 1851, when prospector Samuel Hancock was led by Indian guides on a canoe up the Stillaguamish River.:2 The area was opened to logging after the signing of the Treaty of Point Elliott in 1855, relocating the Stillaguamish tribe to trust lands and the Tulalip Indian Reservation. The U.S. Army built a military road connecting Fort Steilacoom to Fort Bellingham, crossing the Stillaguamish River near the confluence. Wagon roads from the towns of Marysville to the south and Silvana to the west were constructed in the 1880s, bringing entrepreneurs to the logging camps, informally named "The Forks". The area's first store was opened in 1888 by Nels K. Tvete and Nils C. Johnson, and was followed by a hotel with lodging and meals for local loggers.
Two settlements were established on the south side of the confluence in anticipation of the Seattle, Lake Shore & Eastern Railroad building a railroad through the area. G. Morris Haller, son of Colonel Granville O. Haller, founded a settlement on the banks of the Stillaguamish River in 1883, naming it "Haller City". The Seattle, Lake Shore & Eastern Railroad chose to site its depot on higher ground to the south of Haller City, leading contractors Earl & McLeod to establish a new town at the depot on March 15, 1890. The new town was named "Arlington" after Lord Henry Arlington, member of the cabinet of King Charles II of England. Arlington and Haller City were platted within a month of each other in 1890, quickly developing a rivalry that would continue for several years.:804–806
Arlington and Haller City grew rapidly in their first years, reaching a combined population of 500 by 1893, relying on agriculture, dairy farming and the manufacturing of wood shingles as their main sources of income. Both towns established their own schools, post offices, saloons, general stores, churches, social clubs, and hotels. The two towns were separated by a 40-acre (16 ha) tract claimed by two settlers, preventing either town from fully absorbing the other. During the late 1890s, the claim dispute was settled and merchants from Haller City began moving to the larger, more prosperous Arlington, signalling the end for Haller City.:130–133 Today, Haller City is memorialized in the name of a park in downtown Arlington, as well as a middle school operated by the Arlington School District.
Arlington was incorporated as a fourth-class city on May 20, 1903, including the remnants of Haller City (located north of modern-day Division Street). The incorporation came after a referendum on May 5, in which 134 of 173 voters approved the city's incorporation. The new city elected shingle mill owner John M. Smith as its first mayor.:16 In the years following incorporation, Arlington gained a local bank, a cooperative creamery, a city park, a library, electricity, and telephone service.:144
During the early 20th century, Arlington's largest employers remained its shingle mills and saw mills. Other industries, including dairy processing, mechanical shops, stores, and factories, became prominent after World War I, during a period of growth for the city. The Great Depression of the 1930s forced all but one of the mills to close, causing unemployment to rise in Arlington and neighboring cities. The federal government established a Civilian Conservation Corps (CCC) camp near Darrington to create temporary jobs, building structures and firefighting in the Mount Baker National Forest.:243–245 The Works Progress Administration and Civil Works Administration funded the construction of the city's sidewalks, a high school, and a municipal airport that opened in 1934. The outbreak of World War II brought the U.S. Navy to Arlington, resulting in the conversion of the municipal airport into a naval air station in 1943. The airport gained new runways and hangars, and the municipal government was allowed to operate civilian and commercial services in 1946. Ownership of the airport was formally transferred back to the city of Arlington in 1959.:72
On October 19, 1959, a Boeing 707-227 crashed on the banks of the Stillaguamish River's North Fork during a test flight, killing four of eight occupants. The plane, being flown by Boeing test pilots instructing personnel from Braniff International Airways, lost three engines and suffered a fire in the fourth after a dutch roll had been executed beyond maximum bank restrictions. The plane made an emergency landing in the riverbed while unsuccessfully trying to reach a nearby open field.
The completion of Interstate 5 and State Route 9 in the late 1960s enabled Arlington to become a bedroom community for Everett and Seattle. Suburban housing developments began construction in the 1980s and 1990s, driving a 450 percent increase in Arlington's population to 15,000 by 2007. In 1999, Arlington annexed the community of Smokey Point, located along Interstate 5 to the southwest of the city, after a lengthy court battle with Marysville, which instead claimed Lakewood to the west. The city began developing a large business park around the municipal airport in the 1990s, bringing the city's number of jobs to a total of 11,000 by 2003.
The city of Arlington celebrated its centennial in 2003 with a parade, a festival honoring the city's history, sporting events, and musical and theatrical performances. The centennial celebrations culminated in the dedication of the new, $44 million Arlington High School building, attended by an all-class reunion of the old school. In 2007, the city of Arlington renovated six blocks of downtown's Olympic Avenue with wider sidewalks, improved street foliage, and new street lights, at a cost of $4.4 million. The project was credited with helping revitalize the city's downtown, turning Olympic Avenue into a gathering place for residents and a venue for festivals.
On March 22, 2014, a large landslide near Oso dammed the North Fork of the Stillaguamish River and killed 43 people. The landslide closed State Route 530 to Darrington, cutting the town off, leaving Arlington as the center of the coordinated emergency response to the disaster. Arlington was recognized for its role in aiding victims of the disaster and hosted U.S. President Barack Obama during his visit to the site in April.
According to the United States Census Bureau, the city of Arlington has a total area of 9.26 square miles (23.98 km2), of which 9.25 square miles (23.96 km2) is land and 0.01 square miles (0.03 km2) is water. The city is in the northwestern part of Snohomish County in Western Washington, and is considered part of the Seattle metropolitan area. It is approximately 41 miles (66 km) north of Seattle and 10 miles (16 km) north of Everett. Arlington's city limits are generally defined to the south by Marysville at State Route 531 (172nd Street NE) and roughly 165th Street NE, to the west by Interstate 5, to the north by the Stillaguamish River valley, and to the east by the Cascade Range foothills.:E-18 The city's urban growth boundary includes 10.3 square miles (27 km2) within and outside of city limits.:4-2
The city lies on a glacial terrace formed during the Pleistocene epoch by the recession of the Cordilleran ice sheet.:E-18 Arlington covers a series of hills that sit at an elevation of 100 to 200 feet (30 to 61 m) above sea level. Downtown Arlington is located on a bluff above the confluence of the Stillaguamish River and its North and South Forks. Most of Arlington sits in the watersheds of the Stillaguamish River, Portage Creek, and Quilceda Creek.:E-10 From various points in Arlington, the Olympic Mountains, Mount Pilchuck, and Mount Rainier are visible on the horizon.
The Stillaguamish River valley and floodplain, including Arlington, lies in a lahar hazard zone 60 miles (97 km) downstream from Glacier Peak, an active stratovolcano in the eastern part of the county.:E-22 During an eruption 13,000 years ago, several eruption-generated lahars deposited more than 7 feet (2 m) of sediment on modern-day Arlington.
Arlington has a general climate similar to most of the Puget Sound lowlands, with dry summers and mild, rainy winters moderated by a marine influence from the Pacific Ocean. The majority of the region's precipitation arrives during the winter and early spring, and Arlington averages 181 days of precipitation per year. Arlington's location in the foothills of the Cascade Range brings additional precipitation compared to nearby communities, with 46 inches (1,200 mm) annually compared to 33 inches (840 mm) in Everett. Arlington rarely receives significant snowfall, with an average of 7 inches (18 cm) per year since 1922.
July is Arlington's warmest month on average, with high temperatures of 73.6 °F (23.1 °C), while January is the coolest, at an average high of 44.5 °F (6.9 °C). The highest recorded temperature, 98 °F (37 °C), occurred on October 1, 1923, and the lowest, 7 °F (−14 °C), occurred on January 1, 1979.

Arlington's early economy relied heavily on timber harvesting and processing, notably the production of red cedar wood shingles at mills that closed during the Great Depression of the 1930s. Locally, Arlington was known as the "Shingle Capital of the World", although mills in Everett and Ballard produced more shingles at the time. Agriculture and dairy farming emerged as significant industries to Arlington during the early 20th century, with farms lining the floodplain of the Stillaguamish River. A major cooperative creamery and condensery was established in Arlington during the 1910s, but later moved to Mount Vernon after World War II.:18
The transformation of Arlington into a bedroom community for Everett and Seattle during the 1980s and 1990s came with it a move towards a service economy.:1-10 Among the largest employers of Arlington residents are the Boeing Everett Factory and Naval Station Everett. The expansion of the aerospace industry in the Seattle region led Arlington to develop its own municipal airport into an aerospace job center, which includes a high concentration of Boeing subcontractors. As of 2012[update], the airport has 130 on-site businesses that employ 590 people,:9-11 with a total output of $94.5 million annually.
The city of Arlington plans to increase the number of jobs within the city to over 20,000 by 2035,:5-16 bolstered by the proposed designation of the Arlington-Marysville Manufacturing Industrial Center by the Puget Sound Regional Council. The industrial center, located between the two cities near Smokey Point, already includes major distribution centers and other light industry.
Arlington is defined as a non-charter code city and operates under a mayor–council government, with an elected mayor and an elected city council. The mayor serves a four-year term and has no term limits. The current mayor of Arlington is Barbara Tolbert, who was elected in 2011 and re-elected to a second term in 2015. Tolbert's predecessors included John and Margaret Larson, who both served as mayor from 1980 to 1990 and 2003 to 2011, respectively.
The city council is composed of seven residents who are elected in at-large, non-partisan elections to four-year terms. The council also appoints a city administrator to oversee city operations. The council meets twice per month on Mondays in a chamber at city hall in downtown Arlington. According to the Washington State Auditor, Arlington's municipal government employs 128 people full-time and operates on an annual budget of $50 million. The city government switched to a biennial budget in 2017, after an ordinance was passed by the city council in 2016. The municipal government provides emergency services, as well as water and sewage utilities, street maintenance, parks and recreation, an airport, and a cemetery.

The 150-acre (61 ha) park was purchased from the Graafstra family in 2010, and is planned to be developed into sports fields, hiking trails, camping areas, and a swimming beach, in addition to a 40-acre (16 ha) riparian habitat. Across the South Fork is Twin Rivers Park, Arlington's second-largest park, a 50-acre (20 ha) park with sports fields that is owned by Snohomish County but maintained by the city of Arlington. The city's third-largest park, Bill Quake Memorial Park, consists of soccer and baseball fields on 13 acres (5.3 ha) near Arlington Municipal Airport.
The county government also owns the Portage Creek Wildlife Area, a 157-acre (64 ha) wildlife reserve located outside of city limits near downtown Arlington. The reserve was originally a dairy farm that was restored into wetland habitat in the 1990s and 2000s.
Arlington is at the intersection of two major county cycling, walking, and equestrian trails: the Centennial Trail, which runs 29 miles (47 km) from Bryant to Snohomish; and the Whitehorse Trail, which will run 27 miles (43 km) east from Arlington to Darrington. Both trails use right of way acquired by Snohomish County after they were abandoned by the Burlington Northern Railroad in the late 20th century.:7-4 The city of Arlington also maintains a 6-mile (9.7 km) unpaved walking trail around the Arlington Municipal Airport.
The Arlington Municipal Airport hosts the annual "Arlington Fly-In" air show during the weekend after Independence Day. The Fly-In has operated annually since 1969 and is the third-largest event of its kind in the United States, with over 50,000 visitors and 1,600 planes participating.
The Downtown Arlington Business Association hosts several annual events in downtown Arlington, including a car show in June, a street fair on Olympic Avenue in July, and a Viking festival in October.

Arlington has one weekly newspaper, The Arlington Times, which has been published in the Arlington area since 1890. It has been under common ownership with the Marysville Globe since 1964, and both were acquired by Sound Publishing in 2007. The Herald in Everett serves the entire county, including Arlington, and prints daily editions. Arlington is also part of the Seattle–Tacoma media market, and is served by Seattle-based media outlets including The Seattle Times; broadcast television stations KOMO-TV, KING-TV, KIRO-TV, and KCPQ-TV; and various radio stations.
Arlington has been part of the Sno-Isle Libraries system, which operates public libraries in Island and Snohomish counties, since its inception in 1962. A 5,055-square-foot (469.6 m2) library was built near downtown Arlington in 1981 and holds over 54,000 items,:9-12 but has been in need of replacement or renovation since the 2000s. Sno-Isle identified the Arlington Library as a top priority for renovation and expansion in 2016, while also emphasizing the need for a new library to serve Smokey Point.
The volunteer-operated Stillaguamish Valley Pioneer Museum, southwest of downtown Arlington, opened in 1997. The museum overlooks the Stillaguamish River and features preserved household items, logging equipment, and vehicles, historic newspapers and images from the Arlington area, and a model railroad.
The Arlington area has two properties listed on the National Register of Historic Places (NRHP). The Trafton School in Trafton was built in 1888 and re-built in 1912 after a fire. It was listed as a historic place in 2006, shortly before it was closed by the Arlington School District. The Arlington Naval Auxiliary Air Station (part of the modern-day Arlington Municipal Airport) was listed as a historic place in 1995.
Notable people from Arlington include:
Public schools in Arlington are operated by the Arlington School District, which covers most of the incorporated city and also includes the outlying areas of Arlington Heights, Bryant, Getchell, and Sisco Heights. The district had an enrollment of approximately 5,528 students in 2014 and has nine total schools, including one high school, two middle schools, four elementary schools, and two alternative learning facilities.:9-17 In the early 2000s, the school district opened four new schools to replace other facilities as part of a $54 million bond measure passed by Arlington voters in 2000. The Smokey Point neighborhood is served by the Lakewood School District, which is in unincorporated North Lakewood and served the area prior to its annexation by Arlington.
Arlington is located approximately 15 miles (24 km) away from the Everett Community College, its nearest post-secondary education institution, situated in northern Everett. The college has offered basic skills and job training courses at Arlington's Weston High School since 2016, including a branch of its Advanced Manufacturing Training & Education Center.
In 1966, the Smokey Point area was proposed as the location of a four-year public college, with 645 acres (261 ha) offered by the city of Arlington to the state government. The Washington State Legislature decided to build the college instead in Olympia, becoming The Evergreen State College. The Smokey Point area was again offered by Arlington and Marysville as the site of a University of Washington branch campus in the 2000s, but the project was put on hold and later declined by the state legislature in favor of a Washington State University branch campus in Everett.
Downtown Arlington is located near the junction of State Route 9 and State Route 530, which serve as the main highways to the city. From Arlington, State Route 9 travels north into Skagit County and south to Snohomish; and State Route 530 travels west to an interchange with Interstate 5, the main north–south highway between Seattle and Vancouver, British Columbia, and east to Darrington. Within the city is an additional state highway, State Route 531, which connects Smokey Point, the municipal airport, and Gleneagle to Interstate 5 and State Route 9 in the southern part of the city. Other major arterial roads include Smokey Point Boulevard and 67th Avenue NE, which serve as north–south thoroughfares within Arlington.:8-5
Public transportation in Arlington is provided by Community Transit, a public transit authority that operates in most of Snohomish County. Community Transit runs all-day local bus service on one route from Downtown Arlington to Smokey Point, as well as three other routes to Marysville, Everett, Lynnwood, and Stanwood from a transit center in Smokey Point. During peak hours, Community Transit also provides local service from Darrington, and commuter service to the Boeing Everett Factory from a park and ride in downtown Arlington.
Arlington has one active railroad, a 6.9-mile-long (11.1 km) spur line from Marysville to downtown Arlington operated by BNSF Railway (the successor to Burlington Northern). As part of the development of the Arlington Airport business park, BNSF Railway will build two rail spurs leading to the airport in the near future. Arlington does not have passenger rail service, but is near Amtrak stations in Everett and Stanwood.
Historically, Arlington developed along several railroads that have since been abandoned or re-purposed. The Seattle, Lake Shore and Eastern Railway, which spurred the establishment of Arlington in the 1880s, ran north–south through Arlington on its main line between Snohomish and the Canadian border. In 1892, it was acquired by the Northern Pacific Railway, which was acquired by Burlington Northern in 1970. Burlington Northern abandoned the railroad in 1972, favoring a parallel route to the west through Marysville, and it was converted into the Centennial Trail in the 1990s and 2000s. A Northern Pacific branch to Darrington, following the modern-day State Route 530, was built in 1901 and abandoned in 1990; the county government plans to use the right of way for the Whitehorse Trail, a multi-purpose trail.
The city of Arlington owns the Arlington Municipal Airport, located 3 miles (4.8 km) southwest of downtown Arlington. The airport is primarily used for general aviation and light business, and is home to 475 aircraft, including 10 helicopters, 20 gliders, and 23 ultra-light aircraft.:9-11 Approximately 130 businesses are located on airport property, of which one-quarter are involved in aviation-related uses directly impacting the airport.:9-11 In the 1990s, the airport was explored as a candidate for expansion into a regional airport to relieve Seattle–Tacoma International Airport. The plan was ultimately abandoned by 1996, as the Puget Sound Regional Council instead chose to construct a third runway at Seattle–Tacoma International Airport.
Electric power in Arlington is provided by the Snohomish County Public Utility District (PUD),:9-16:A20 a consumer-owned public utility that purchases most of its electricity from the federal Bonneville Power Administration (BPA). The BPA operates the region's system of electrical transmission lines, including Path 3, a major national transmission corridor running along the eastern side of Arlington towards British Columbia. Cascade Natural Gas and Puget Sound Energy provide natural gas to Arlington residents and businesses north and south of State Route 531, respectively;:9-16 two major north–south gas pipelines run through Arlington and are maintained by the Olympic Pipeline Company, a subsidiary of BP, and the Northwest Pipeline Company, a subsidiary of Williams Companies.
The city of Arlington provides water and water treatment to approximately 5,548 customers within a 25.3 square miles (66 km2) area within and around the city limits. The city's water is sourced from groundwater deposits near Haller Park on the Stillaguamish River and near Arlington Municipal Airport, as well as water purchased from the Snohomish County PUD that is source from Spada Lake. The Smokey Point neighborhood is served by the City of Marysville's water system.
Wastewater and stormwater are collected and treated by the municipal government before being discharged into the Stillaguamish River basin. Arlington's municipal solid waste and single-stream recycling collection and disposal services are contracted by the municipal government to Waste Management; the Snohomish County government and Republic Services also operate a transfer station in Arlington.
Arlington is part of the Snohomish Public Hospital District No. 3, which operates the Cascade Valley Hospital, a 48-bed general hospital.:9-18 The hospital was established in 1909 and was the last independent hospital in Snohomish County at the time of its acquisition in 2016. The city is also served by community clinics operated by Cascade Valley (and Skagit Regional Health) as well as The Everett Clinic and the Community Health Center of Snohomish County.
