Assembly Republican David Steffen plans to introduce a bill Wednesday to replace the state’s 119-year-old prison at Green Bay with a new facility in the area. With almost eleven-hundred inmates, Steffen says the maximum security lockup in Allouez is 143-percent above its capacity, and the prison’s problems are not going away. Steffen, who’s from Howard, wants a private firm to build the new prison, with the state to lease it. He figures it would cost about four-million dollars less to rent each year, than the state’s current maintenance cost of 19-million for the Green Bay prison, which is on the both the national and state registries for historic places. Allouez officials say it would help the community if the site goes on the tax roll, saying the old prison could be used for housing or business purposes, and perhaps light industry.
