Section 106 of the National Historic Preservation Act of 1966 (NHPA) requires Federal agencies to take into account the effects of their undertakings on historic properties, and afford the Advisory Council on Historic Preservation
a reasonable opportunity to comment. Agencies must
- determine if their undertakings will affect properties that meet the criteria for inclusion in the National Register of Historic Places, and
- assess and resolve any adverse effects from the undertaking on the identified historic properties.
Public involvement is a key to a successful Section 106 process. The views of the public must be solicited and considered throughout the process.
