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 XXXXX inmates in KY), varying by size/capacity.

Renovation could be cheaper initially but incurs higher long-term costs and $60M lost tourism revenue.
