The U.S. Army Corps of Engineers plans to award a noncompetitive firm fixed-price contract to the Confederated Tribes of Warm Springs for managing historic properties affected by the Federal Columbia River Power System. Services include monthly visits to Memaloose Island to document erosion, site conditions, and impacts like vandalism, while providing tribal cultural insights and recommendations. The contract requires unique, confidential knowledge held only by the tribe, with no known alternatives. Performance location is Memaloose Island, and the award is intended before 30 September 2026. No budget amount is specified.
