Subject: Pre-Solicitation Notice (PSN) – Request for Proposal (RFP) 140P2026R0086

Reference: KNRI 257081 KNIFE RIVER ELBEE BEND BANK STABILIZATION This pre-solicitation announcement is to advise the Industry that NPS DSC intends on issuing an RFP Solicitation for the Construction Services described below, in support of the above referenced project requirement at Elbee Bend is in the Knife River Indian Village National Historic Site (park), Mercer County, North Dakota.

This PSN is not a formal Solicitation in itself, but rather a Synopsis of forthcoming RFP 140P2026R0086.

Specific instructions on submitting your proposal will be contained in the solicitation documents to be issued on or after 07/06/2026.

General Project Description and Scope:

This project is located at Knife River Indian Village National Historic Site (park), Mercer County, North Dakota. Elbee Bend is in the Knife River Indian Village National Historic Site (park) and contains 64 archeological sites. The Knife River, a tributary to the Missouri River downstream of the Garrison Dam, runs the length of the park in Mercer County, North Dakota. The Elbee Bend Site on the Knife River is actively eroding, creating a threat to archeological resources, a utility pole approximately 130 feet from the migrating bend, and County Road 37. The cut bank is approximately 20 feet high. The purpose of this project is to stabilize the Elbee Bend site to protect archeological resources in the park.

The surrounding area is urban with limited staging on site.

Note any unique material delivery requirements.

The construction site is 25 -50 miles from nearest suppliers and lodging facilities.

The Park will remain open during construction, thus contract activities and logistics must be structured and scheduled to minimize visitor impact.

The site requires protective measures to ensure the surrounding area remains undisturbed.

The structure is a natural/cultural resource.

The anticipated period of performance of 356 calendar days includes any potential weather shutdown.

There are seasonal/other shutdowns mandated through the construction season.

Winter construction may be required.

Work to be performed under this Construction Services project requirement includes:

This project will stabilize the Elbee Bend of the Knife River by installing self-healing riverbank protection in combination with strategic planting of vegetation. Riprap will be placed at the base of the steep eroding bank to provide toe protection and to prevent excessive bank contact and scouring of the bend. Additional material and riprap

B01 Page 2 of 2 v1 Mar2025 will be buried in the bank at one or both the ends of the protection structure, forming keys that further prevent water from scouring behind the riverbank. Construction will also include compacted filling along the protection area and up to the full height of the riverbank, which ensures there are no voids or trenches behind the protection structure.

Vegetation or other bioengineering will be planted on the stabilization as appropriate.

This project will stabilize approximately 1200 linear feet of bank along the Knife River. The most important measurable result of this stabilization is preventing further destruction and loss of the Elbee Village Archeological Site. Knife River Indian Villages NHS preserves and protects archeological resources related to the lifestyles of Northern Great Plains Indian peoples, and the preservation Elbee Village is fundamental to maintaining this park purpose.

Stabilizing the riverbank will also protect infrastructure including County Road 37, electric utility poles, parking for fishing access, and park boundary fencing. County Road 37 is the only access for the National Park Service to the northern portion of the park and also provides public access to private property. The USACE estimates that at current rates of erosion, the road will be lost in the next 10 years. Of course, the archeological site and associated resources would be long gone before that time.

The completion of this project will be an important step in the implementation of the Archeological Resources Management Plan EIS (2018). The EIS defined a process for comprehensive archeological resources management, including a measured and strategic process for riverbank stabilization. The Elbee Bend has been identified as the highest priority stabilization need for the park and is quickly becoming an emergency. The EIS defined indicators and standards that any more than 0% additional loss would trigger action. That standard has been surpassed and action must be taken. Unpredictable weather events could result in catastrophic loss of resources and infrastructure.

Addressing the need for stabilization as soon as possible will avert this outcome and costly emergency actions.

In addition to the protection of resources, preservation of infrastructure, and plan implementation, this stabilization will increase recreational opportunities for visitors. The stabilization itself will become a trail for visitor use along the river. Stabilization will connect from the Elbee Bend to the fishing hole and then to the Sakakawea stabilization/trail.

This will allow visitors to hike, recreate, and fish in a location that they were not previously able to access.
