Portland has spent more than $12 million over six years on Centennial Mills, a city-owned site, but redevelopment plans stalled and the project was never realized as plans shifted from demolition to reuse.
Portland officials warn the Centennial Mills demolition in the Pearl District will be explosive, with residents within about a half-mile asked to stay indoors as a four-blast sequence unfolds; text alerts and sirens will precede the detonations to address safety concerns and air-quality impacts.
Union Pacific says it plans to resume rail traffic alongside the burned and crumbling Centennial Mills site in Portland, despite city warnings about the warehouse’s instability and the surrounding foundations.
Cadaver dogs indicated possible human remains in the Centennial Mills warehouse rubble. Authorities say demolition is necessary to reduce collapse risk and allow a more complete search for bodies as the investigation continues.
After the Centennial Mills warehouse fire in Portland, debris in the Pearl District tested positive for asbestos. The DEQ coordinated with the EPA to collect air and building-debris samples, while officials warned residents not to disturb ash and debris. Air monitoring outside the immediate fire area shows a low health risk, but The Fields Park was closed as a precaution and cleanup plans are underway, potentially involving a controlled demolition. Residents voiced concerns about communication and safety as investigations continue.
