(a) Boundary changes.

1. (1) A boundary alteration shall be considered as a new property nomination. All forms, criteria and procedures used in nominating a property to the National Register must be used. In the case of boundary enlargements only those owners in the newly nominated as yet unlisted area need be notified and will be counted in determining whether a majority of private owners object to listing. In the case of a diminution of a boundary, owners shall be notified as specified in § 60.15 concerning removing properties from the National Register. A professionally justified recommendation by the State Historic Preservation Officer, Federal Preservation Officer, or person or local government where there is no approved State Historic Preservation Program shall be presented to NPS. During this process, the property is not taken off the National Register. If the Keeper or his or her designee finds the recommendation in accordance with the National Register criteria for evaluation, the change will be accepted. If the boundary change is not accepted, the old boundaries will remain. Boundary revisions may be appealed as provided for in §§ 60.12 and 60.15.
2. (2) Four justifications exist for altering a boundary: Professional error in the initial nomination, loss of historic integrity, recognition of additional significance, additional research documenting that a larger or smaller area should be listed. No enlargement of a boundary should be recommended unless the additional area possesses previously unrecognized significance in American history, architecture, archeology, engineering or culture. No diminution of a boundary should be recommended unless the properties being removed do not meet the National Register criteria for evaluation. Any proposal to alter a boundary has to be documented in detail including photographing the historic resources falling between the existing boundary and the other proposed boundary.

(b) Relocating properties listed in the National Register.

1. (1) Properties listed in the National Register should be moved only when there is no feasible alternative for preservation. When a property is moved, every effort should be made to reestablish its historic orientation, immediate setting, and general environment.

2. (2) If it is proposed that a property listed in the National Register be moved and the State Historic Preservation Officer, Federal agency for a property under Federal ownership or control, or person or local government where there is no approved State Historic Preservation Program, wishes the property to remain in the National Register during and after the move, the State Historic Preservation Officer or Federal Preservation Officer having ownership or control or person or local government where there is no approved State Historic Preservation Program, shall submit documentation to NPS prior to the move. The documentation shall discuss:

   1. (i) The reasons for the move;
   2. (ii) The effect on the property's historical integrity;
   3. (iii) The new setting and general environment of the proposed site, including evidence that the proposed site does not possess historical or archeological significance that would be adversely affected by the intrusion of the property; and
   4. (iv) Photographs showing the proposed location.

3. (3) Any such proposal with respect to the new location shall follow the required notification procedures, shall be approved by the State Review Board if it is a State nomination and shall continue to follow normal review procedures. The Keeper shall also follow the required notification procedures for nominations. The Keeper shall respond to a properly documented request within 45 days of receipt from the State Historic Preservation Officer or Federal Preservation Officer, or within 90 days of receipt from a person or local government where there is no approved State Historic Preservation Program, concerning whether or not the move is approved. Once the property is moved, the State Historic Preservation Officer, Federal Preservation Officer, or person or local government where there is no approved State Historic Preservation Program shall submit to the Keeper for review:

   1. (i) A letter notifying him or her of the date the property was moved;
   2. (ii) Photographs of the property on its new site; and
   3. (iii) Revised maps, including a U.S.G.S. map,
   4. (iv) Acreage, and

   5. (v) Verbal boundary description.

      The Keeper shall respond to a properly documented submittal within 45 days of receipt with the final decision on whether the property will remain in the National Register. If the Keeper approves the move, the property will remain in the National Register during and after the move unless the integrity of the property is in some unforeseen manner destroyed. If the Keeper does not approve the move, the property will be automatically deleted from the National Register when moved. In cases of properties removed from the National Register, if the State, Federal agency, or person or local government where there is no approved State Historic Preservation Program has neglected to obtain prior approval for the move or has evidence that previously unrecognized significance exists, or has accrued, the State, Federal agency, person or local government may resubmit a nomination for the property.

4. (4) In the event that a property is moved, deletion from the National Register will be automatic unless the above procedures are followed prior to the move. If the property has already been moved, it is the responsibility of the State, Federal agency or person or local government which nominated the property to notify the National Park Service. Assuming that the State, Federal agency or person or local government wishes to have the structure reentered in the National Register, it must be nominated again on new forms which should discuss:

   1. (i) The reasons for the move;
   2. (ii) The effect on the property's historical integrity, and

   3. (iii) The new setting and general environment, including evidence that the new site does not possess historical or archeological significance that would be adversely affected by intrusion of the property.

      In addition, new photographs, acreage, verbal boundary description and a U.S.G.S. map showing the structure at its new location must be sent along with the revised nomination. Any such nomination submitted by a State must be approved by the State Review Board.

5. (5) Properties moved in a manner consistent with the comments of the Advisory Council on Historic Preservation, in accord with its procedures (36 CFR part 800), are granted as exception to § 60.12(b). Moving of properties in accord with the Advisory Council's procedures should be dealt with individually in each memorandum of agreement. In such cases, the State Historic Preservation Officer or the Federal Preservation Officer, for properties under Federal ownership or control, shall notify the Keeper of the new location after the move including new documentation as described above.
