Note: That table also shows that zonable area drops slower than road cost, but don’t forget that lower density is also increased cost for any service with a radius of effect. So if you make a 10×10 grid, you’ll spend 50% more than you need to for the area you’ll get.

So you’re also paying 16% less on the roads to grid the same area with more stuff.įor some concrete numbers, let’s compare a 60×60 area (as it divides evenly in a bunch of ways) using a variety of block sizes and the basic small two-lane road: And for the 10×10 blocks, those 64 tiles of zoning need 40u of roads (1.6tiles/u), but with a 12×12 block you get 96 tiles of zoning out of only 48u of roads (2tiles/u). How’s that? Well, you need to pay for the roads. But not only is it more dense, but it’s also cheaper. Now, I admit that only about 4% more zoning doesn’t sound that exciting. How much better? ⅔ of the area (66.66…%) instead of just 64%. Note: Coincidentally, that’s also the maximum segment length for an axis-aligned road in CSL. So yes, it’s a block length of exactly 12 that gives the best density. Can we prove it? Sure, let’s go back to Calculus I:

That shows that the “obvious” 10×10 grid is actually only as good as a 15×15 grid: It’s hard for me to grok that quotient in my head, so let’s just graph it and see what happens: (Here, and in the rest of the section, we assume a small-2u-road).įor the general case of a square of side ?, the zoneable area is (?-2)²-max(0, ?-10)² - the area inside the road minus the area in the middle where the zoning doesn’t reach - and the total area is ?². I always figured that if I was going to build a nice, regular, square grid that of course it should be 10×10: That way each of the blocks is fully zonable and the road length highlight and road guideline circles make it easy to draw.įor the 10×10 grid, the calculation is simple: we get 8² zonable tiles in a 10² tile area, for a density of exactly 64%.
