John Baldwin, director of the state Department of Corrections, told a legislative budget panel Tuesday he plans to end his tenure with the state agency next January after 42 years and three months. The leader of the system that oversees Iowa’s prisons and community-based corrections said he has seen many changes in his continuous service with the department, most notably a prison population that grew from about 1,500 when he arrived to the current 8,098 head count of offenders behind bars. Baldwin told members of the Legislature’s joint justice systems budget subcommittee that he expects the prison population to stabilize at around 8,100 and at about 30,800 in CBC facilities statewide. He submitted a fiscal 2015 budget request for $375.6 million and 3,931 full-time staff that represented less than a half-percent increase over current operations. He said he expects the department will open the new Iowa State Penitentiary in April or May and plans to repurpose rather than close the Clinical Care Unit (CCU) to house minimum-security “live out” offenders.
