Section 106 of the National Historic Preservation Act
Section 106 of the National Historic Preservation Act of 1966 (NHPA) requires that federal agencies take into account the effects of their undertakings on historic properties, and afford the Advisory Council on Historic Preservation a reasonable opportunity to comment. Section 106 is one of the foundational laws in protecting the nation’s cultural and historic resources.
A Citizen’s Guide to Section 106 Review, produced by the Advisory Council on Historic Preservation is a great document that provides an overview of the Section 106 process and review.
The National Trust for Historic Preservation commissioned a study to look into the effectiveness of Section 106. It further explores the idea that Section 106 doesn’t mandate preservation—It merely creates a process to ensure consideration of adverse effects on historic properties.
Section 4(f) refers to the original section within the Department of Transportation (DOT) Act of 1966. The Act set requirements for the consideration of park and recreational lands, wildlife and waterfowl refuges, and historic sites in transportation project development.
