To designate the General George C. Marshall House, in the Commonwealth of Virginia, as an affiliated area of the National Park System, and for other purposes.

This section formally establishes the General George C. Marshall House in Leesburg, Virginia, as an affiliated area of the National Park System. It also defines the specific geographic area included in this designation by referencing a map. This means the site is recognized for its national significance and will be managed in cooperation with the National Park Service, but it does not become a full unit of the system.

This provision specifies that the George C. Marshall International Center will be the primary management entity for the affiliated area. It authorizes the Secretary of the Interior to provide technical assistance and financial aid for marketing, marking, interpretation, and preservation, and mandates a cooperative agreement outlining roles and responsibilities consistent with NPS standards. Furthermore, it requires a comprehensive management plan to be completed within three years.

This section explicitly states that the Secretary of the Interior is not authorized to acquire property at the affiliated area or assume managerial or financial responsibility for its operation. It also protects the land use rights of adjacent private property owners and prohibits the creation of buffer zones, ensuring activities outside the Marshall House property are not controlled or limited by its designation.
