A consultant examining future needs at the Dubuque County Jail says the facility is operating beyond its capacity, based on his assessment of how inmates should be housed. Rod Miller, president of the nonprofit Community Resource Services Inc., told county supervisors this week that while there are more than 210 beds and short-term holding spaces in the jail, he would put its optimal operating capacity at closer to 140 inmates. The jail’s current daily average is about 180 inmates. Sheriff Joe Kennedy says that Miller was using different criteria than the sheriff’s department uses and that there is space for the current inmates at the jail. However, he still has concerns about crowding in the facility.
