In 2016, The 106 Group Ltd. conducted an intensive architecture/history evaluation of the Upper Harbor Terminal (UHT) site to:

• Evaluate the site individually as a historic district for listing in the National Register of Historic Places (NRHP)
• Reevaluate it as a local Minneapolis landmark
• Evaluate the four Monolithic Domes located at the site to determine if they are eligible for listing in the NRHP and as local Minneapolis landmarks

This 87-page report documents their findings and recommendations.
