Ahhh, these are all fantastic and I am horribly envious of everyone's patience and ability to count tiles and figure all of the spacing out in your towns!
I actually tried the moment I started my town, but kept getting off count and thrown off my my river. And then the process of going in and counting where everything is within each acre, and how large they are was just far too tedious.
I ended up just overlaying a grid onto my town map, and as I've noticed other people mention before, I'm not too sure on how accurate it is. I think it'll suit me enough to figure out basically where I want things to go, however.
I haven't actually started landscaping or working on projects yet. A part of me is debating going back and laying down tiles again, just so everything will be perfect.
I would suggest, though, for anyone planning to do that to try to count and lay them down in one day without saving!
And then begin the process of making your map so that you can exit the game with saving and not have to go around and pick up every single tile you put down x_x
Though that would also imply having to count tiles and create a map all in one day, which also sounds painful.
