Storage Yards with build requirements, is it possible to do this?
I have been trying and trying to get it to work by using a requirement like building a stone road etc. and I also tried once by trying a kind of cemetery code swap, but every time I click on the icon, I can draw out the area, but than 'Crash-CTD'. I'm sure I've got all the dialog functions correct.

Storage yards are just empty open areas. Awhile ago, I was thinking about an enclosed walled storage yard with an empty space in the middle, but, it'll bring a lot of problems with the 3D design and citizens walking through it. It's better to work it as a building.
