If you go by the standard, prisons are to be tucked away somewhere at the outer corners of your map, forgotten and never to be looked at again.
Where I live, prisons are right smack inside the city, nimby or not ... And biz around them thrives, bars, shops, eateries and more, catering to the endless stream of visiting relatives, lawyers or jailbirds on leave.
So here is my urban jail for low wealth neighborhoods or the fringes of an industrial complex, with higher capacity (which of course means higher costs as well).
Lot size: 6x4
Capacity: 2000
Plop Cost: 3500
Bulldoze Cost: 350
Monthly cost: 600
Power, Water and Pollution are slightly higher than standard
Note: This does NOT replace the original jail.
Just move the files into the 'Plugins' directory under My Documents/Sim city 4.
Simply bulldoze any of these lots in your cities, then remove the file(s) from the plugin directory.
Just plop these lots wherever you deem appropriate ;-)
As with all things from the internet, USE AT YOUR OWN RISK. I tested the lots and they work fine for me. No one but you is to be held responsible if your computer is subject to termination of any kind. If you have any questions or comments, please feel free to join the simpeg forums.
