I ask similar questions and get different answers. I have gotten several towns up to 1000 people and in some of them I don’t need as many compost yards while others have needed several more. From what I’ve personally gathered it appears to me that the proximity of the compost yards to the housing can be a factor but to argue that point I’ve had a compost yard just out of negative desirability range and the houses still didn’t have their waste collected. To that end, I think it’s a matter of the game queueing up the buildings in order of collection and not how close they are to those buildings that need immediate collection.
