Spokane Valley, WA

Spokane Valley became a city on March 31, 2003, in what municipal records describe as Washington's largest incorporation and the nation's second-largest single incorporation at the time. The boundary was new; the communities and industries inside it were not. Mullan Road crossed the valley in the nineteenth century, and irrigation later supported extensive apple orchards. Opportunity grew as one of several named communities across the broad floor east of Spokane. The Spokane Valley Heritage Museum now occupies the historic Opportunity Township Hall. Exhibits on Native history, Mullan Road, orchard agriculture, early communities, and later commerce carry the valley's pre-incorporation history into the present city. Interstate 90, Sprague Avenue, and large industrial tracts organize much of the present city. In 2023, its largest fields of work included retail, health and social assistance, government, manufacturing, construction, transportation and distribution, and wholesale trade.

The scale of industrial activity is clearest at the Spokane Business and Industrial Park. A 2026 draft city economic chapter describes a campus of over 625 acres, about five million square feet, roughly 120 companies, and over 4,500 workers. Near the eastern edge, Kaiser Aluminum's Trentwood rolling mill employed roughly 1,000 people and had recently completed a $25 million expansion when the 2026 draft was prepared. These workplaces share the valley with commercial strips and residential districts, giving the city several centers, with no single traditional downtown. Two long paths reveal older transportation routes at a slower pace. The paved Appleway Trail follows 5.8 miles of former Milwaukee Road right-of-way from Farr Road to Tschirley Road, with sections built between 2015 and 2021 and an onward connection toward Liberty Lake for walking and bicycling.

About seven miles of the Centennial Trail cross Spokane Valley beside the Spokane River. Transit follows the main east-west corridors. Route 9 runs along Sprague between central Spokane and the Valley Transit Center. Opened in 2025, the Mirabeau Transit Center serves Route 7 between Liberty Lake, downtown Spokane, and Spokane International Airport, along with local and peak-period routes. Most of the city is also underlain by the Spokane Valley-Rathdrum Prairie Aquifer, which has federal sole-source designation. The visible routes share the valley's broad east-west direction; beneath them, the aquifer adds a less visible geography. Mirabeau Point is the city's clearest civic cluster.

The 55.5-acre Mirabeau Point Park occupies the west bank of the Spokane River, and the 54,000-square-foot CenterPlace Regional Event Center sits near Mirabeau Meadows, Mirabeau Springs, and the Centennial Trail. Discovery Playground occupies the same campus beside the senior center and YMCA. Each September, Valleyfest spreads parades and programs among Sprague Avenue, CenterPlace, Mirabeau Point Park, and Plantes Ferry. The Spokane County Interstate Fair begins on the Friday after Labor Day and runs for ten days at the Fair and Expo Center, while nearby Avista Stadium hosts Spokane Indians baseball. The fair's livestock pens and exhibits of preserved food, flowers, photographs, and handmade work give the old orchard-and-farm valley a visible place in the contemporary city.
