Blood, Trauma, and Biohazard Cleanup in West Haven-Sylvan, OR

West Haven-Sylvan is an unincorporated census-designated place in Washington and Multnomah counties, north of U.S. Route 26, and it is partially bordered to the east by Portland while the Beaverton city limits form its southern and western borders.

West Haven-Sylvan had a population of 9,299 at the 2020 census, up from 8,001 in 2010 and 6,009 in 1990, and the 2000 census counted 3,395 households in the CDP.

In 1850, pioneer Nathan B. Jones settled at the head of Tanner Creek and platted lots for a community he called Zion Town, hoping it would become the new capital of Oregon, and he was murdered during a robbery in 1894.

Because the name Zion would have caused confusion with two earlier Oregon post offices of the same name, a resident suggested Sylvan, from Silvanus, the Roman deity of the woods, and the Sylvan post office operated from 1890 to 1906.

The CDP covers 2.24 square miles, all land, and nearly all of the community drains west into tributaries of Beaverton Creek in the Tualatin River watershed.

U.S. Route 26, the Sunset Highway, passes just south of West Haven-Sylvan within the Beaverton city limits, leading east 5 miles to downtown Portland and northwest 73 miles to Seaside.

Parks in the West Haven-Sylvan area include Merritt Woods Natural Area, Mitchell Park, Roger Tilbury Memorial Park, Sunset Hills Memorial Park, and Tualatin Hills Park.

Fire protection and emergency medical services for West Haven-Sylvan are provided by Tualatin Valley Fire and Rescue, and Providence St. Vincent Medical Center is within the area.

Most of the CDP in Washington County is covered by Beaverton School District 48J, with West Tualatin View Elementary School in the CDP, Cedar Park Middle School, and Beaverton High School, while Portland School District 1J covers the Multnomah County portions.
