The National Research Council is jointly administered by the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine. The mission of the TRB, one of six major divisions of the National Research Council, is to promote innovation and progress in transportation through research. In an objective and interdisciplinary setting, the TRB facilitates the sharing of information on transportation practice and policy by researchers and practitioners; stimulates research and offers research management services that promote technical excellence; provides expert advice on transportation policy and programs; and disseminates research results broadly and encourages their implementation.

Treatment and Use (Historic Structure Report)
This narrative presents and evaluates alternative uses and treatments for a historic structure. Emphasis is on preserving extant historic material and resolving conflicts that might result from a structure's "ultimate treatment." Part 2 concludes by recommending a treatment and use responding to objectives identified by park management. In most cases, design work does not go beyond schematics.

A treatment is a strategy, usually determined in park planning documents that defines an appropriate type of action including preservation, rehabilitation, restoration, and reconstruction, as defined by the Secretary's Standards. Treatment and designated use affect the level of investigation. Generally, the more intensive the treatment and the greater the impact of the proposed use, more exhaustive research and investigation are needed, thereby affecting the breadth of scope of the proposed HSR. Restoration and reconstruction tend to be the most intensive treatments.

Tribal Historic Preservation Officer (THPO)
Tribal Historic Preservation Officer (THPO) is the tribal official appointed by the tribe's chief governing authority or designated by a tribal ordinance or preservation program who has assumed the responsibilities of the SHPO for purposes of section 106 compliance on tribal lands. As formal participants in the national historic preservation program, the THPOs responsibilities include identifying and maintaining inventories of culturally significant properties, nominating properties to national and tribal registers of historic places, conducting section 106 reviews of Federal agency projects on tribal lands, and conducting educational programs on the importance of preserving historic properties. The National Park Service designates tribal Historic Preservation Officers.

Note: Only three NPS units - Canyon de Chelly National Monument, Navajo National Monument, and Hubbell Trading Post National Historic Site - consult with the THPO in lieu of the SHPO for undertakings occurring on, or affecting historic properties on, tribal lands.
