The Army has formalized an ACUB process that is initiated locally at the installation level but reviewed, approved, and funded centrally. For ACUBs, the cooperating partner purchases easements or fee simple property from a willing seller with funds contributed by the Army and other partners in approved priority areas. These areas provide a natural buffer between military training lands and residential or commercial activities in perpetuity. The partner, not the Army, receives the deeded interest in the property and provides for long-term monitoring and management. Pursuant to the terms of the cooperative agreement and with land owner permission, the installation may retain access rights to conduct compatible military training.
