Blood & Biohazard Cleanup Near Stonehedge Village Bothell, WA

Bothell is a city that straddles two counties — King and Snohomish — near the northeast end of Lake Washington in the Seattle area's Eastside region.

The townsite was established in 1870 and platted in 1888 by David Bothell and his family, for whom the city is named, on land that was the historic home of the Indigenous Sammamish people.

Bothell was incorporated on April 14, 1909, and its early economy rested on logging and farming along the Sammamish River before it became a bedroom community.

Bothell had a population of 48,161 at the 2020 census, up sharply from 33,505 in 2010.

Census Bureau survey figures for 2020–2024 counted about 19,448 households in Bothell.

The University of Washington Bothell was established in 1990, and in 2000 it opened a permanent campus shared with Cascadia College on a former ranch site whose wetlands blocked an earlier plan to build a shopping mall there.

Bothell's 1992 annexation of the Canyon Park area added about 11,400 people, nearly doubled the city's population, and turned Bothell into a dual-county city.

Today Bothell's economy centers on biotechnology and high-tech firms clustered along North Creek and in the Canyon Park business district.

Bothell students attend schools in the Northshore School District, including Bothell High School and North Creek High School.

The Sammamish River Trail runs through Bothell along the river, connecting the city to the Burke-Gilman Trail network and Lake Washington.
