Hmm. I like to have a few divided areas for separate "zones". You saw my town yesterday, though I don't know how well you'd remember it

On the east side of my village, I have the Town Hall at the center of the northmost tip of a large land area. I made this area into a "civic district" with the police station, a player home as a "recreational center" and the town plaze in the south. I then have a narrowish strip of land on the south with the majority of my animal houses, which I've lovingly dubbed "Animaltown", with my house on a little peninsula west of Animaltown, somewhat isolated from the animal villagers to reflect my importance!
In the center of my village I have a relatively large "field" with my fruit orchard. I treat this area sort of like farmland (headed by grouchy Farmer Cyrano, who lives in the southwest near the bridge to Animaltown) but I'll probably end up making a public park in the northern section of the field. A very narrow strip in the northeast that I've made into a camping ground (Campsite, Camping Cot, and Picnic Blanket when I finally unlock it). In the northwest I have my sister's house, Re-Tail, the Roost is being built, and one animal house.
Basically, I like having several areas I can make into these "zones" so my town has several districts.
