Work is underway to reclaim a former pumice mine so that the expansion of OSU-Cascades can continue. The camera below looks west toward the deepest portion of the mine, where the bottom was 100 feet below the surrounding land. During the reclamation work, crews removed fill material in the mine, processed it and replaced it to create a structurally consistent material. Sheer cuts on the sides of the mine were re-sloped to improve access into the campus and provide material to raise the bottom of the mine to the final design elevation — as much as 40 feet in places. Additionally, remediation of an adjacent demolition waste landfill — also owned by the university — yields clean soil and rock to be used as fill in the pumice mine. OSU-Cascades has initiated the expansion of its campus onto the reclaimed mine site with construction of a Edward J. Ray Hall, which was completed in September 2021.
The campus expansion will happen slowly — perhaps one building every two years — and in phases over the coming decades. During Phase 1A, infrastructure and off-campus transportation infrastructure will also be developed.
Our goal is to share the story of the campus development and the ways we will minimize its impact on our surrounding community. Sign up for email updates.
