Emergency Crime Scene and Biohazard Cleanup in Duvall, WA

Duvall is a city in northeastern King County, located on State Route 203 in the Snoqualmie Valley halfway between Monroe and Carnation, and its official motto is 'Small Town. Real Life.'

The Duvall area is the historic home of the Snoqualmie people, and the townsite was homesteaded by logging brothers Francis and James Duvall, who arrived in 1871; the community was settled in 1875 and named for the Duvall family.

Around 1909, the neighboring town of Cherry Valley was physically relocated to Duvall so the Chicago, Milwaukee and St. Paul Railroad could build its line along the Snoqualmie River, and the moved town was briefly renamed Cosgrove before becoming Duvall.

Duvall was platted in 1910 and incorporated on January 6, 1913.

The 2020 census counted 8,034 people in 2,702 households in Duvall, a dramatic rise from just 258 residents in 1920 and 2,770 in 1990, as the town became a bedroom community for Eastside job centers.

Duvall's population grew by roughly 50 percent between 1990 and 1997 alone during its shift from a logging and farming town to a commuter community.

On April 28, 1968, nearly 3,000 fans attended a concert at a Duvall farm where an upright piano was dropped from a helicopter, an event remembered as the Piano Drop that helped inspire the Sky River Rock Festival later that year.

McCormick Park, on the Snoqualmie River, is Duvall's largest park and hosts city events including Duvall Days each June and outdoor SummerStage concerts, and it serves as a trailhead for King County's Snoqualmie Valley Trail.

Duvall is served by the Riverview School District, whose sole comprehensive high school is Cedarcrest High School.

The Snoqualmie Valley around Duvall is prone to flooding from late fall to early spring, a recurring feature of life in the city.
