Section 106 of the National Historic Preservation Act (NHPA) of 1966 requires Federal agencies to consider the effects of their undertakings on historic properties. Through consultation with interested parties, the goal is to identify historic properties potentially affected by the undertaking, assess their effects, and seek ways to avoid, minimize, or mitigate any adverse effects on historic properties.
Historic property means any prehistoric or historic district, site, building, structure, or object included in or eligible for inclusion in the National Register of Historic Places. It also includes artifacts, records, and remains related to and located within such properties. In addition, it also includes properties of traditional religious and cultural importance to an Indian tribe or Native Hawaiian organization that meet the National Register criteria.
