Towns develop organically… it’s rare that there’s a plan to build a 10k person town or 100k city.
Perhaps the closest approximation would be a large subdivision. They’d need to develop a master plan, determine what phases will be built when and then first determine the infrastructure, like water, electricity, sewers, gas and roads. They’d also need to determine things like rain drainage, abide by zoning or work to implement zoning to lay out lots and other features. Then they’d built out the infrastructure needed, survey the lots, etc. before starting to build and/or sell them.
