This is a city template I've created that might prove useful for when you wish to either create or edit your existing cities. As far as I can tell, the template is accurate, but being human, I've likely made some mistakes.
If you happen to find any, simply post here or PM me detailing the issue.
Anyway, I hope you enjoy.
NOTE: I realize that there are many values already present in the spreadsheet; however, these are here so that if the comments are not as useful as I thought them to be, you might be able to see how the values are strung together through example.
