Section 4(f) Compliance for Historic Properties


Section 4(f) of the DOT Act of 1966 is triggered by funding or approval from a U.S. DOT agency for a project that proposes "use" of historic property or land from a publicly owned park, recreation area, or refuge. With a focus on historic properties, examine the stringent approval standards of this substantive law and discuss ways to better integrate and streamline Sections 4(f) and 106 with the National Environmental Policy Act (NEPA) process.

Detailed Agenda


MaryAnn Naber, former Federal Highway Administration Federal Preservation Officer, senior program analyst and FHWA liaison at the Advisory Council on Historic Preservation, and member of the Transportation Research Board’s Committee on Historic and Archeological Preservation in Transportation; specializing in Section 106 and Section 4(f)

Evaluation Comments

"A well-organized, easy-to-follow review of the 4(f) process."

"The seminar exceeded expectations by clarifying so many terms and language that I have had questions about regarding de minimus and programmatics."

"Clarified issues about when to use and when not to use 4(f)."

"A wonderful course; very informative and thought-provoking."

"The seminar provided a much stronger understanding of Section 4(f). Case studies were very helpful."
