In 1940 the Army created what was to become the 17,165 acre Umatilla Army Chemical Depot (UMCD) in Northeastern Oregon. On November 14, 2008 the United States Army issued a surplus determination for the UMCD property. The 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). The following EDC application is submitted by the CDA.
In total, an estimated 1,477 positions were lost with Base closure representing total labor income of $76 million annually. The impact has been felt regionally across Morrow and Umatilla Counties, Oregon and as far north as Tri-Cities, Washington. The Redevelopment Plan calls for the creation of a 7,500 acre National Guard training facility, 5,700 acre multi-use refuge, and approximately 3,965 acres of industrial/agriculture/right-of-way redevelopment acreage. If approved, the EDC is projected at full build-out to generate approximately 4,249 new positions for the region, $285 million in direct and indirect payroll benefits, and $3.6 million in property taxes to support community services. Due to anticipated slow absorption rates and other factors, the above mentioned benefits will likely require decades to be realized, but the EDC represents the best potential redevelopment scenario for the regional community.
