Auburn, WA

Auburn occupies the broad valley where the Green and White rivers pass through the corridor between Seattle and Tacoma. The level ground supported farms and the Northern Pacific's Seattle–Tacoma line, which began operating through the area in 1883–84, yet it also exposed settlement to recurring floods. The town incorporated as Slaughter in 1891 and adopted the name Auburn in 1893. Mud Mountain Dam on the White River and Howard Hanson Dam on the Green later reduced the flood danger. That combination of rivers, rail, and engineering is still legible: much of the city's housing, industry, and transportation infrastructure spreads across the valley floor, with hills rising along its edges. The same valley is part of the ancestral territory of Duwamish and Upper Puyallup communities.

Land set aside in 1857 became the Muckleshoot Reservation, which lies partly within and beside present-day Auburn. The Muckleshoot Indian Tribe remains based there as a sovereign government, with current departments devoted to culture, education, fisheries, health, housing, transit, and public works. Auburn's southeast side includes a jurisdiction and civic life that predate the railroad town. The reservation remains a present-day neighbor, and tribal stewardship of fisheries connects contemporary government with the rivers that have always structured this valley. Working life reflects Auburn's position between the two largest cities on Puget Sound. State Route 167 and nearby port connections support aerospace production, manufacturing, wholesale trade, warehousing, and distribution. In 2019, manufacturing accounted for over one-fifth of jobs located in Auburn and employed 13 percent of the city's residents.

Boeing remained the largest employer in the city's 2022 profile, followed by a broader mix that included retail, manufacturing, wholesale businesses, and MultiCare's downtown medical center. The ten largest employers accounted for 23 percent of Auburn jobs in 2022, down from 85 percent in 2002. By 2022, Auburn's employment base had spread well beyond one large industrial company to factories, logistics facilities, stores, health care, and smaller local firms. Downtown adds commuter rail and cultural space to this industrial corridor. Auburn Station serves Sound Transit's S Line commuter trains, while the adjoining transit center brings together regional express service and local bus routes. Nearby, the Postmark Center for the Arts occupies Auburn's former post office, a Works Progress Administration building completed in 1937.

The building served postal customers until the 1960s, then spent over four decades as a county medical center before closing in 2009. Auburn bought it in 2016 and adapted it for exhibitions, music, dance, literary programs, and classes. In 2026, Postmark became home to Auburn's new artist-in-residence program. South of downtown, Les Gove Park gathers the Auburn Library and White River Valley Museum on one public campus. Museum displays include Native American history, a reconstructed cabin, a railroad caboose, and a 1920s town scene. The original Postmark postal lobby now hosts art and instruction inside a building that has served Auburn in three distinct ways.
