This bill proposes to designate the General George C. Marshall House in the Commonwealth of Virginia as an affiliated area of the National Park System . The designation aims to preserve and interpret the historic site, with its administration managed consistent with applicable laws and the specific provisions of this Act. The George C. Marshall International Center is established as the primary management entity for the affiliated area. The Secretary of the Interior is authorized to provide technical and financial assistance for marketing, interpretation, and preservation through cooperative agreements, and must enter into an agreement delineating management roles and responsibilities. However, the bill explicitly limits the Secretary's role, prohibiting property acquisition or direct managerial and financial responsibility for the site's operation. It also includes provisions to protect the land use rights of adjacent private property owners and clarifies that no buffer zones are created around the affiliated area, ensuring activities outside are not restricted by the designation.
