Biohazard Cleanup Near Simonds Estates Kirkland, WA

Kirkland is a city in King County, Washington, a suburb on the eastern shore of Lake Washington across from Seattle.

The city was founded in 1888 by British-born steel magnate Peter Kirk, who dreamed of building a great steel mill town on Lake Washington — a mill that was never actually built.

Kirkland was incorporated in 1905 with a population of only about 532 people.

Kirkland had a population of 92,175 at the 2020 census, making it the sixth-largest city in King County and the twelfth-largest in Washington.

Census Bureau survey figures for 2020–2024 counted about 38,771 households in Kirkland.

Kirkland was the original home of the Seattle Seahawks, whose headquarters and training facility sat at the Lake Washington Shipyard (now Carillon Point) for the team's first ten seasons, from 1976 to 1985, and later at Northwest University in the city until 2007.

Warehouse giant Costco was once headquartered in Kirkland, and although its headquarters moved to Issaquah, the company's Kirkland Signature store brand still carries this city's name.

American video game company Valve, creator of the Steam platform, was also founded in Kirkland.

Kirkland consolidated with the neighboring town of Houghton on July 31, 1968, uniting the Lake Washington waterfront communities under one city government.

On June 1, 2011, Kirkland nearly doubled in population overnight by annexing the Finn Hill, North Juanita, and Kingsgate neighborhoods, adding roughly 33,000 residents.
