KNRI/257081 Knife River Indian Village National Historic Site - Elbee Bend Bank

The Department of the Interior National Park Service National Office has issued a Special Notice for the Knife River Indian Village National Historic Site's Elbee Bend Bank Stabilization project located in Mercer County, North Dakota. The project focuses on stabilizing approximately 1,200 linear feet of riverbank to protect 64 archeological sites and critical infrastructure, including County Road 37 and utility poles. This high-priority stabilization effort aims to prevent further erosion of the Elbee Village Archeological Site and mitigate potential infrastructure loss. The U.S. Army Corps of Engineers has estimated that without intervention, County Road 37 could be lost within 10 years. The stabilization method will involve using riprap, compacted fill, and strategic vegetation planting to address erosion concerns.

The National Park Service anticipates issuing a request for proposals around June 20, 2025, with a mandatory site visit scheduled for June 11, 2025, at 0930 CST. The project is set aside for small businesses and falls under NAICS Code 237990 with a small business size standard of $45 million. The performance period is estimated at 356 calendar days and may include winter construction. Eligible contractors must be classified as small businesses and have experience in civil engineering, riverbank stabilization, and archeological site preservation. As an additional benefit, the project will create a new trail connecting the Elbee Bend to a fishing hole, enhancing recreational opportunities for park visitors. The stabilization efforts align with the Archeological Resources Management Plan and represent a critical preservation initiative to protect historically significant archeological resources and local infrastructure.
