The bill designates the General George C. Marshall House in Leesburg, Virginia, as an affiliated area of the National Park System and identifies the George C.
Marshall International Center as the nonfederal management entity. It references a specific map (numbered 999/189,974, dated September 2023) to describe the property, directs that management follow laws and policies generally applicable to National Park units, and authorizes the Secretary of the Interior to provide technical assistance and enter cooperative agreements for marketing, interpretation, marking, and preservation.
Crucially, the measure limits federal responsibility: the Secretary cannot acquire property or assume operational or financial control of the site. The bill also contains explicit protections for adjacent private-property rights and a clear prohibition on creating buffer zones or regulating outside activity solely because it can be seen or heard from the Marshall House — a provision that narrows the practical reach of the affiliated designation.
At a Glance
What It Does
Designates the Marshall House as an affiliated area of the National Park System, identifies the George C. Marshall International Center as the management entity, and authorizes the Secretary of the Interior to provide technical assistance and enter into cooperative agreements for specified purposes. It requires an agreement between the Secretary and the management entity that aligns roles and responsibilities with NPS policies and standards.
Who It Affects
The management entity (George C. Marshall International Center), the Department of the Interior/National Park Service in a technical and oversight role, the property owner(s) and adjacent private landowners in Leesburg, and local tourism and historical-interpretation stakeholders who might participate in programming or marketing.
Why It Matters
The bill gives the site federal recognition and access to NPS technical resources without creating a federal unit or funding obligation, which preserves local control but leaves open questions about long-term preservation funding, oversight authority, and how federal standards will be enforced in practice.

What This Bill Actually Does
The core effect of the bill is to add the General George C. Marshall House to the roster of National Park System affiliated areas.
That status is mostly honorary but actionable: it allows the Secretary of the Interior to partner with the named nonfederal manager and to provide technical and financial assistance through cooperative agreements targeted at marketing, interpretive programming, signage, and preservation projects. The bill ties the designation to a particular depiction on a map (999/189,974, September 2023), which frames what the affiliated area covers without transferring land to the federal government.
The statute requires the Secretary to enter into an agreement with the George C. Marshall International Center that spells out who does what and to ensure that management occurs consistently with policies and standards that apply to National Park units.
That creates a formal governance link: the Center keeps operational control, but the agreement will be the mechanism through which NPS standards and expectations are articulated and (to some degree) enforced.The bill also draws firm lines around federal authority. It expressly forbids the Secretary from acquiring property at the site or assuming responsibility for day-to-day operation or funding.
It further protects adjacent private-property owners by preserving their land-use rights and by stating that no buffer zones are created; visibility or audibility of outside activities from the site cannot be used to control those outside activities. In short, Congress gives federal recognition and partnership tools while stopping short of federal ownership, operation, or land-use regulation beyond the boundaries shown on the map.Practically, that structure means the success of preservation and visitor services will depend on the capacity and resources of the George C.
Marshall International Center and on the content of the required agreement with the Secretary. The NPS can offer expertise and limited financial support for specific purposes, but it cannot replace the manager's obligations.
The bill leaves open how much federal funding — if any — will be available, how disputes about standards will be resolved, and how the affiliated status will affect local planning and tourism strategies.
The Five Things You Need to Know
The bill ties the affiliated-area boundary to a map: 'General George C. Marshall House, Proposed Affiliated Area,' map no. 999/189,974, dated September 2023.
It names the George C. Marshall International Center as the management entity and requires a written agreement between that entity and the Secretary setting out roles and responsibilities consistent with NPS policies.
The Secretary may provide technical assistance and enter cooperative agreements that can include financial assistance specifically for marketing, marking (signage), interpretation, and preservation.
Section (f) bars the Secretary from acquiring property at the affiliated area or from assuming managerial or financial responsibility for its operation or maintenance.
Section (h) prohibits creation of buffer zones and states that activities outside the Marshall House cannot be regulated merely because they are visible or audible from within the property.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Establishment of affiliated area
This subsection formally designates the General George C. Marshall House as an affiliated area of the National Park System. That status recognizes the site's national significance and creates the statutory basis for federal cooperation without converting the property into a federal unit or transferring title.
Boundary described by map
The affiliated area's extent is defined by reference to a specific map (no. 999/189,974, September 2023). Referencing a map rather than precise metes and bounds creates some flexibility but also potential ambiguity: the phrase 'area generally depicted' can leave room for interpretation about exact boundaries and which parcels or features fall inside the affiliated area.
Administration consistent with NPS laws and policies
This clause requires management to occur 'in a manner consistent with' the Act and laws generally applicable to National Park units. Practically, that imports NPS policy expectations — e.g., preservation standards and interpretive approaches — but it does not automatically subject the site to all enforcement mechanisms available for federal units.
Designation of management entity
The bill designates the George C. Marshall International Center as the manager for the affiliated area. That makes the Center the primary operational actor responsible for day-to-day care, programming, and local stewardship, subject to the terms of the cooperative agreement with the Secretary.
Cooperative agreements and technical assistance
The Secretary may enter cooperative agreements and provide technical assistance, including financial assistance, for marketing, marking, interpretation, and preservation. The subsection also requires a formal agreement that delineates roles and aligns the Center's responsibilities with NPS policies and standards, creating the legal vehicle for oversight and collaboration.
Limits on federal authority; private-property protections; no buffer zones
These subsections make three limits explicit: the Secretary cannot acquire property or assume operational/financial responsibility (f); adjacent private-property rights remain unaffected (g); and the statute will not create buffer zones or allow regulation of outside activities simply because they are visible or audible from the property (h). Together, these provisions confine federal reach and reinforce local control over land use outside the affiliated area.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- George C. Marshall International Center — gains federal recognition, an explicit management role, and access to NPS technical assistance and targeted financial support for marketing, signage, interpretation, and preservation.
- Local tourism businesses and Leesburg's visitor economy — can leverage the affiliated designation for marketing and partner on programming that attracts heritage tourists without the site becoming federally managed.
- Historians, educators, and interpretive partners — receive a clearer platform and potential federal expertise for developing nationally oriented programming about George C. Marshall and related history.
- National Park Service staff — benefit professionally by extending NPS expertise and standards to a nationally significant site without adding a full federal unit; this allows programmatic reach with limited budgetary commitment.
Who Bears the Cost
- George C. Marshall International Center — retains primary operational responsibility and likely bears ongoing maintenance, staffing, and programming costs unless specific cooperative funding is provided.
- Department of the Interior/NPS — assumes administrative and oversight obligations tied to cooperative agreements and the required management agreement, which creates workload without authorizing acquisition or full operational funding.
- Local governments and infrastructure providers — may face incremental costs (parking, signage, traffic management) if visitation increases but the bill does not provide federal funding for those municipal needs.
- Adjacent private-property owners — while legally protected from new federal land-use controls, they may experience increased visitor activity, privacy concerns, or property impacts related to a higher-profile designation.
Key Issues
The Core Tension
The central dilemma is between federal recognition with light-touch cooperation and the practical needs of historic preservation: the bill gives the site prestige and access to NPS expertise but refuses to commit federal funds or ownership, forcing reliance on a nonfederal manager and negotiated agreements — a setup that favors local control but may under-resource long-term preservation and limit enforceable federal oversight.
The bill deliberately splits recognition from responsibility: it confers federal recognition and limited assistance while withholding federal ownership or operational funding. That architecture preserves local control but raises open implementation questions — chiefly, how much and what form of federal financial support will actually materialize through cooperative agreements, and whether that support will be sufficient to meet preservation and interpretive needs.
The requirement that management occur 'consistent with' NPS laws and policies creates expectations but not a clear enforcement ladder; the management agreement will be the practical mechanism for translating standards into obligations, yet the statute does not specify required contents, timeline, or dispute-resolution procedures for that agreement.
Another tension is the map-based boundary description and the 'no buffer zones' language. Referencing a map leaves room for boundary disputes or differing interpretations of what falls 'generally' within the affiliated area.
At the same time, the explicit ban on buffer zones aims to protect neighboring landowners but limits tools commonly used around federal sites to manage visual, acoustic, or development impacts. That trade-off can complicate coordinated preservation planning and local land-use management, particularly where outside activities affect the historic character or visitor experience but fall outside the affiliated boundary.
