The U.S. Army Corps of Engineers - St. Paul District requires a real estate appraisal and a UASFLA (Yellow Book) compliant appraisal report with market value and highest and best use analysis for a 331.33 acre site known as Lower Grey Cloud Island in the City of Cottage Grove in Washington County, Minnesota. The property is located just a few miles from St. Paul, MN. The appraisal will require an in person site inspection. The property is privately owned and has been used for sand and gravel mining for over 50 years.

A copy of the Environmental Assessment Worksheet is included with the solicitation for informational purposes.

It is recommended that interested parties read the story Amrize drops plan for gravel pit expansion in Mississippi River bed by Mary Divine in the 13 February 2026 edition of the Pioneer Press for more background information. ----- This solicitation is 100 percent set-aside for small businesses under NAICS 531320, Offices of Real Estate Appraisers, with a SBA small business size standard of $9,500,000. ---- This solicitation is a Request for Quotes (RFQ), with the contract recipient being selected on the basis of Best Value to the Government.
