For over 30 years, Nacht & Lewis has provided design services to Sacramento County and the Sheriff’s Department for multiple projects at the Rio Cosumnes Correctional Center (RCCC). Recent projects include a 448-bed medium security (Level II) dormitory, completed in 2000 and two 192-bed, maximum-security housing units. In addition, the firm has designed a new administration building, a new secure perimeter fence with a vehicle sallyport and visitors gatehouse.

Nacht & Lewis continues to work with the Sheriff’s Department to plan the expansion of RCCC to accommodate a growing and changing inmate population. Master planning for the expansion includes new special use housing for medical/mental health treatment, a new intake and booking facility, new education and vocational training classrooms, a new food service and laundry facility and the necessary housing and infrastructure to accommodate up to 5,000 inmates.
