Summary: The Office of the Secretary of Defense and the service headquarters provide overall policy guidance and negotiate agreements on the treatment of the military's historic properties. However, most decisions on historic properties are made at the installation level. The installations are responsible for identifying and evaluating properties to determine if they are eligible to be listed on the National Register of Historic Places as well as maintaining all properties that are listed on or have been determined eligible for listing on the National Register. The military lacks complete and reliable data on the number of its historic properties. None of the services have a centralized database that comprehensively identifies all of their respective historic properties. Data is not available on the costs to to maintain or repair historic properties. Cost data GAO examined at several installations showed that, overall, the day-to-day maintenance historic properties was similar to maintenance on non-historic properties.
