"Renovating Alcatraz for prison use is estimated at $235-370M upfront per recent analyses due to structural decay retrofitting and isolation. Annual ops: $40-75M 3x mainland prisons. Building a new federal prison costs $400-900M (e.g. $500M for 1400 inmates in KY) varying by size/capacity. Renovation could be cheaper initially but incurs higher long-term costs and $60M lost tourism revenue"
