West Valley

Loop 303 / I-10 West

Stretching west of I-17, the West Valley is a broad swath of established and rapidly expanding suburbs. Glendale hosts State Farm Stadium (Arizona Cardinals) and Desert Diamond Arena (Arizona Coyotes), while Peoria is a major spring training destination. Surprise has nearly tripled in population since 2000, and Goodyear and Buckeye are among Arizona's fastest-growing cities, fueled by large master-planned developments and proximity to Luke Air Force Base. Loop 303 has opened new development corridors further west, making this region the metro's primary growth frontier.
