Mill Creek is a city in Snohomish County, Washington, United States. It is located between the cities of Everett and Lynnwood, approximately 20 miles (32 km) northeast of Seattle. The city has a population of 20,926 as of the 2020 census. The city lies along State Route 527 and North Creek, a tributary of the Sammamish River, on the east side of Interstate 5.

The city is one of the wealthiest suburbs in the Seattle metropolitan area and was originally a planned community conceived in the 1970s. The planned development was centered around a country club and golf course, with other development occurring nearby in later phases. It was incorporated as a city in 1983, shortly after the completion of the first phase of development, and underwent major population growth due to continued suburban development and annexation of nearby areas. The city's downtown area is centered around the Mill Creek Town Center, a mixed-use lifestyle center and retail complex that opened in 2004.

History

Development

The Mill Creek area was originally settled in the early 20th century by various farming families, from whom several local placenames are now derived. After the construction of the Bothell–Everett Highway in 1913 as part of the Pacific Highway, two junctions at Murphy's Corner and Wintermute's Corner gained small stores and filling stations to serve visitors. In 1931, Doctor Manch N. Garhart acquired 800 acres (320 ha) in the area and used it to grow Gravenstein apples and Bartlett pears while also raising cattle. The Garhart property, named Lake Dell Farm for a small reservoir built by local families, was later sold in 1967 to real estate developers after the market for local lumber and fruits had declined.

The Garhart property, along with several neighboring farms, were optioned by various real estate developers in the 1960s and 1970s as a potential master planned community due to its proximity to the recently completed Interstate 5. It would be the first modern planned city in Washington state, following in the footsteps of earlier planned cities like Longview, built in 1918. The community, named "Olympus", was planned to include 3,300 acres (1,300 ha) in its first phase with 1,300 acres (530 ha) for homes, an industrial park, a shopping center, and a golf course. After a local recession in the early 1970s, the development project was sold in 1973 to Tokyu Land Development and designed by a subsidiary of the Obayashi Corporation named United Development. The development was renamed "Mill Creek", beating out the Chinook Jargon word "Klahanie", although there had never been a mill in the vicinity and a waterway of that name was not present in the area until the 2000 renaming of Smokehouse Creek.

Mill Creek's master plan was submitted to the county council in January 1974. A homeowners association was established in December 1974 with funding from United Development to manage the area's security patrol, street maintenance, and other tasks. The initial plan included consist of 4,600 homes, with eventual plans to house 12,000 people, a 260-acre (110 ha) park, and an 18-hole golf course. Construction began in early 1975 on the golf course and adjoining country club, while the first homes were under construction by the following year. The first set of homes were designed to resemble country residences, with large floorplans and prominent use of wood furnishings, and sold for an average of $65,000 (equivalent to $334,000 in 2022 dollars). Tokyu Land Development later re-used these home designs for the domestic market in Japan, where they were sold under the "Mill Creek" brand in the 1990s. The final phase of the original Mill Creek development, consisting of 33 condominiums, was completed in late 2003.

Incorporation and annexations

A majority of the first phase's 1,767 homes and condominiums were completed by early 1983, when an incorporation petition was submitted by residents after reaching the population threshold of 3,000 needed for cityhood. At the time, the homeowners association and county government had already provided much of the area's infrastructure and maintenance requirements, but local residents resisted attempts to raise property tax assessments. Mill Creek was officially incorporated as a city on September 30, 1983, ten days after a vote of residents passed, and encompassed 1.92 square miles (5.0 km²). Mill Creek was the first new city to be incorporated in Snohomish County since Brier in 1965 and the newest in the state since Ocean Shores in 1970.

In the years following incorporation, Mill Creek reduced its property tax rates and formed its own police department, library, postal address, and land-use board. The city's telephone system was split between three long-distance calling areas by GTE until the state utilities and transportation commission approved a consolidated calling area for toll-free service. Sid Hanson, the chairman of the incorporation committee, was elected as the city's first mayor and served a single term until declining to run for re-election in 1987. The city government's offices moved four times by the end of the decade, between various leased buildings that all served as temporary city halls. A separate post office serving the city was promised at the time of incorporation, but was not opened until 1994.

The city attempted its first annexations in 1986, but an advisory vote of existing residents rejected one proposal and the city council deferred action on another. Mill Creek approved its first annexation, an 88-acre (36 ha) parcel southeast of the main development, in July 1987, while the nearby city of Everett began its own annexations of areas to the north of Mill Creek. In 1989, the city proposed a major annexation of 350 acres (140 ha), a 25 percent increase in size, to add undeveloped commercial parcels on the west side of the Bothell–Everett Highway. The western annexation was initially opposed by the county government, but was approved alongside four other annexations after Mill Creek agreed to share costs for road improvements to handle additional traffic demand.

Everett attempted to annex the entire Murphy's Corner area in the late 1980s, but was forced to split the neighborhood at 132nd Street with Mill Creek after a decision by the state court of appeals and additional arbitration by boundary review boards. The Henry M. Jackson High School was opened in 1994 and is located on the Mill Creek side of Murphy's Corner, which was annexed the following year. A private high school, Archbishop Murphy High School, was opened in 1999 on a 22-acre (8.9 ha) campus in northeastern Mill Creek. The 553-acre (224 ha) Thomas Lake area in the northeastern corner of the city, bordered to the north by 132nd Street and east by Seattle Hill Road, was annexed in 2005 and added 2,200 residents to the city's population. The annexations of other developed subdivisions, lacking the original development's upscale image, created a divide between residents on the issue of further growth. Residents in several potential annexation targets preferred to be left alone by Mill Creek, due to its "snobbish" reputation, which faded as new neighborhoods were absorbed into the city.

21st century

In the late 1980s, Mill Creek drafted a comprehensive plan that would transform its newly-annexed commercial area into a mixed-use downtown area to support the growing city. The 23-acre (9.3 ha) downtown development would include a large public park, shopping areas, recreational facilities, multi-use trails, and office buildings. After difficulty in finding a suitable developer, the Mill Creek Town Center began construction in 2001 and the first phase opened three years later. The second phase was completed in 2007, with 26 retail buildings, a medical clinic, condominiums, and a downtown plaza.

The Bothell–Everett Highway (now State Route 527) remained a two-lane rural highway through Mill Creek until the start of an expansion and improvement program in the 1990s. It was widened to four lanes with a center turn lane, and also gained bicycle lanes, sidewalks, and new landscaping features. The section through Mill Creek, from 164th Street to 132nd Street, was completed in 2006 and required the construction of retaining walls and detention ponds due to the limited space for the road. The project also included new bus stops that were later upgraded with the opening of the Swift Green Line bus rapid transit system in March 2019.

The city government began planning for a second urban village, to be located in newly-annexed areas at the northeast edge of the city, in 2007. The retail and residential development, named the East Gateway, would have been located on 52 acres (21 ha) along 132nd Street, and was originally slated to be anchored by a Wal-Mart until the company scrapped plans after protests from local residents. The eastern half of the development began construction in 2012 and will encompass 210 apartments, 104 townhouses, office space, and retail. Development of the remaining western half was approved in 2019 and branded as "The Farm at Mill Creek", consisting of 354 apartments, retail space, workforce housing units, and office space. It will be anchored by the first suburban Amazon Go in the state, and a hotel.

Media

The Mill Creek library, operated by Sno-Isle Libraries

Mill Creek is served by several community publications, including the twice-monthly Mill Creek Beacon, the weekly News of Mill Creek, and the quarterly Mill Creek Living magazine. The Beacon was founded in 2014 and is owned by Beacon Publishing, which also operates weekly newspapers in Edmonds and Mukilteo. The Mill Creek View is a biweekly newspaper founded by Fred Fillbrook that has served the area since January 1991. A regional weekly newspaper, The Enterprise, formerly published a Mill Creek edition until a consolidation in 2009.

The city's public library was constructed in 1987 and expanded several times by Sno-Isle Libraries, its operator. Due to overcrowding at the current building, the city government considered a proposal to build a new library atop a Target store in the East Gateway urban village, but the plan fell through. The Mill Creek branch has 15,000 monthly visitors and the highest hold and pickup rate in the Sno-Isle Libraries system. The building was renovated in 2024 to improve its HVAC systems to serve as a cooling center during heat waves.

Infrastructure

Transportation

Mill Creek lies east of Interstate 5, the main north–south freeway through the Seattle metropolitan area with connections to Downtown Seattle and Everett. The city is bisected from north to south by State Route 527 (the Bothell–Everett Highway), which continues to Bothell. The two highways are connected by a pair of east–west streets, 164th Street and 128th Street (State Route 96), which continue further east into the residential neighborhoods of Mill Creek and towards State Route 9.

The city's public transportation is provided by Community Transit, which also serves most of the county with local and commuter bus routes. The county's second bus rapid transit route, the Swift Green Line, travels along State Route 527 and has several stops in Mill Creek, connecting the city to Paine Field and northern Bothell. A third bus rapid transit route, the Orange Line, opened in 2024 to connect Mill Creek to Link light rail at Lynnwood Transit Center. Other local routes connect Mill Creek to Everett, Lynnwood, Silver Firs, and Snohomish. During rush hours, an express route connects Silver Firs and the 132nd Street corridor to Lynnwood Transit Center. The Ash Way Park and Ride is located west of the Mill Creek Town Center and has additional Community Transit and Sound Transit Express routes. A Link light rail extension to Everett is planned to open in 2036 with stations at Ash Way and Mariner Park and Ride near Mill Creek.

A private airfield, Martha Lake Airport, operated west of modern-day Mill Creek from 1953 to 1998. It has since been converted into a county park, after the owners rejected a proposal to develop it into a housing subdivision. The nearest commercial airport is Paine Field, located 3 miles (4.8 km) northwest in Everett.

Utilities

Electric power in Mill Creek is provided by the Snohomish County Public Utility District (PUD), a consumer-owned public utility that serves all of Snohomish County.
