Is the extra density worth being less regular? IвЂ™ll leave that up to you. Getting up to 75% density takes 10Г—32, which is more oblong than I personally like for a grid. How much better? Well, 10Г—16 has a density of 70%, an extra 5% more than the 12-square. Indeed, if you restrict yourself to integers (so you can draw it with Snap to Road Length), then the only things that beat the best square block are О± в€‹. So thereвЂ™s a surprising amount of choice if you just want to do better than the 10Г—10 block:Д«ut your choices are far more limited if you want to beat a 12Г—12 block: The density formula for an О±Г—ОІ block is ((О±-2)(ОІ-2) вЂ“ (О±-10)(ОІ-10))/(О±ОІ), assuming both sides are 10-or-longer for simplicity (itвЂ™s clear that if both are smaller than 10 itвЂ™s worse than the square, and I donвЂ™t care what happens for silly things like a 5Г—50 block).

Rectangles, as they get longer and longer, can arbitrarily approach the limitвЂ of 80% density. Then the optimal-density square grid is 16Г—16.Д«ut you pay a heavy density price for the larger roads: only 50% of the area is usable for zoning. What if youвЂ™re using a 4u-wide road, like the Medium and Large Roads? YouвЂ™ll fit 1вЃ„24 more RICO in the same space but spend 1вЃ„6 less on the roads, compared to a 10Г—10 grid. If you want the densest square grid, make it 12Г—12 (using small roads). Note: That table also shows that zonable area drops slower than road cost, but donвЂ™t forget that lower density is also increased cost for any service with a radius of effect. So if you make a 10Г—10 grid, youвЂ™ll spend 50% more than you need to for the area youвЂ™ll get. So youвЂ™re also paying 16% less on the roads to grid the same area with more stuff.ДЇor some concrete numbers, letвЂ™s compare a 60Г—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 10Г—10 blocks, those 64 tiles of zoning need 40u of roads (1.6tiles/u), but with a 12Г—12 block you get 96 tiles of zoning out of only 48u of roads (2tiles/u). HowвЂ™s that? Well, you need to pay for the roads. But not only is it more dense, but itвЂ™s also cheaper. Now, I admit that only about 4% more zoning doesnвЂ™t sound that exciting. How much better? в…” of the area (66.66вЂ¦%) instead of just 64%. Note: Coincidentally, thatвЂ™s also the maximum segment length for an axis-aligned road in CSL.

So yes, itвЂ™s a block length of exactly 12 that gives the best density. Can we prove it? Sure, letвЂ™s go back to Calculus I: That shows that the вЂњobviousвЂќ 10Г—10 grid is actually only as good as a 15Г—15 grid: ItвЂ™s hard for me to grok that quotient in my head, so letвЂ™s just graph it and see what happens: (Here, and in the rest of the section, we assume a small-2u-road).ДЇor the general case of a square of side ?, the zoneable area is (?-2)ВІ-max(0, ?-10)ВІ - the area inside the road minus the area in the middle where the zoning doesnвЂ™t reach - and the total area is ?ВІ. I always figured that if I was going to build a nice, regular, square grid that of course it should be 10Г—10: That way each of the blocks is fully zonable and the road length highlight and road guideline circles make it easy to draw.ДЇor the 10Г—10 grid, the calculation is simple: we get 8ВІ zonable tiles in a 10ВІ tile area, for a density of exactly 64%.
