Survey and Inventory

Beginning October 1, the federal government entered a shutdown and as a result, non-essential services are now suspended until funding legislation is approved. The Minnesota State Historic Preservation Office (MN SHPO) may be unable to submit Federal Historic Preservation Tax Incentive Program applications, National Register of Historic Places nominations, and other materials to the National Park Service (NPS) for review. MN SHPO continues to accept and review all submissions regardless of program and will submit materials to our NPS colleagues as soon as we are allowed to do so. While the National Register and Tax Incentive programs are most impacted, there may also be other federal agencies that are furloughed and therefore not able to proceed with consultation and submit project reviews to the MN SHPO as required under Section 106 of the National Historic Preservation Act of 1966. For assistance with locating NPS program applications, forms and publications or to inquire about the status of projects, please reach out to MN SHPO program staff.

August 2025: Changes to Archaeology Report Submittals for SHPO Review

Minnesota’s Statewide Historic Inventory consists of two primary resource types, commonly referred to as "above-ground resources" and "archaeological resources." These two resource types are recorded and maintained separately for a variety of reasons, most notably is that some archaeological and interdisciplinary information is limited to qualified archaeologists.
