In relation to statutory permits, on 2 August 2024 ABMC received a letter from the ‘Division of Historic Preservation’ of the Commonwealth of the North Mariana Islands’ regarding the Section 106 Consultation.

With exception of a small Japanese Pillbox in the vicinity of the memorial that is to be preserved, the letter confirms that “no historic properties affected” and “no further archaeological work is required” as a consequence of ABMC’s proposal to restore the existing memorial to its original configuration.
