On November 14, 2008 the United States Army issued a surplus determination for the UMCD property. The Local Redevelopment Authority (LRA) comprised of Morrow County, Umatilla County, Confederated Tribes of the Umatilla Indian Reservation, Port of Morrow and Port of Umatilla completed and adopted a Redevelopment Plan in 2010. The destruction of the UMCD stockpile of chemical weapons was completed in 2011 and Base closure occurred in 2012. In September of 2014 the LRA reorganized itself as an I-LRA, recognized by the Secretary of the Army, and was renamed the Columbia Development Authority (CDA).
