- Burlington — Thumbnail History (historylink.org)
Burlington is located in western Skagit County, just north of the county seat of Mount Vernon. The community was first established in 1882 as a logging camp, developed into a small town during the early 1890s, and incorporated in 1902. Agriculture has always been one of the biggest industries in the city, though extensive commercial development along Burlington Boulevard between the late 1980s and late 2000s changed this to some extent. The city had an estimated 8,783 residents in 2017, and in 2019, Burlington remained a pleasant, small community, one that was proud of its small-town appeal.
