The Minnesota State Historic Preservation Office (SHPO) and the Minnesota Department of Transportation (Mn/DOT) and their consultants have developed the Minnesota Historic Property Record (MHPR) in order to establish an archival format for the documentation of a historic property. These guidelines are primarily used by state and federal agencies when a historic property is demolished or otherwise adversely affected by a project.
