Advisory Council on Historic Preservation


The following provides an overview of the Advisory Council on Historic Preservation and its programs related to transportation.

The Advisory Council on Historic Preservation is an independent federal agency that promotes historic preservation by providing a forum for influencing federal activities, programs, and policies that impact historic properties.  ACHP advises the President and Congress on national historic preservation policy and is the only entity with the legal responsibility to encourage federal agencies to factor historic preservation into federal project requirements.

ACHP works with federal agencies to help improve how they consider historic preservation values in their programs. One of the ACHP’s key roles is to administer the process of reviewing impacts of federal actions on historic properties under the National Historic Preservation Act of 1966 (NHPA), known as the Section 106 review process.

Section 106 requires federal agencies to take into account the effects of their undertakings on historic properties and afford the ACHP a reasonable opportunity to comment. The historic preservation review process mandated by Section 106 is outlined in regulations issued by ACHP.  Revised regulations, "Protection of Historic Properties" (36 CFR Part 800), became effective January 11, 2001.

Federal agencies are responsible for initiating Section 106 review, most of which takes place between the agency and state and tribal officials. Appointed by the governor, the State Historic Preservation Officer (SHPO) coordinates the state’s historic preservation program and consults with agencies during Section 106 review.  Agencies also consult with officials of federally recognized Indian tribes when tribal lands or historic properties of significance to such tribes are involved. Some tribes have officially designated Tribal Historic Preservation Officers (THPOs), while others designate representatives to consult with agencies as needed.

According to ACHP, Section 106 review requires federal agencies to do the following:
