The new prison reflects current prison design of smaller low-rise separate buildings where prisoners can be more easily isolated from the general population. In 2012 the facility received a 100% rating and the accolades from an assessment team from the American Correctional Association (ACA) (who have been auditing the sites since 1988). Three independent evaluators visited the prison facilities to check on more than 500 standards, including mental health services, safety issues, and other aspects of the facility related to humane treatment of inmates. The USDB received a top rating in all of the standards despite having a portion of its staffing deployed to Iraq.
