About Mountlake Terrace

Mountlake Terrace is a suburban city in Snohomish County, Washington, United States. It lies on the southern border of the county, adjacent to Shoreline and Lynnwood, and is 13 miles (21 km) north of Seattle. The city had a population of 21,286 as of the 2020 census.

Mountlake Terrace was founded in 1949 by real estate developers on the site of a disused airfield, intending to provide low-cost housing for veterans. Within five years, the community had grown to over 5,000 people and was incorporated as a city in 1954 to provide municipal services. An industrial park was developed at the northwest corner of the city, which was connected by Interstate 5 after it opened in 1965. Mountlake Terrace originally had several small shopping centers that declined due to the local economy and a pair of arsons in 1990.

The city government began developing a downtown revitalization plan with mixed-use buildings in the 2000s, with hopes of growing beyond a bedroom community for Seattle commuters. Mountlake Terrace station, a major bus hub, opened in 2009 and is also served by Link light rail service, which began in 2024. The city has several parks, including access to Lake Ballinger, and hosts an annual summer festival that is part of Seafair.
