Other laws/rules/customs
All dead belong to the government, and will be raised as undead to be used as troops/manual labour.
The more your population grows the more troops/manual labour you get that you don't have to feed.
There is a specific Ministry of Reclamation, with Necromancers, working in desecrated, specially prepped facilities, using corpse crafter feats.
Animals can also be Reclaimed, an undead ox/or horse never tires
Any ships you have would be rowed by undead
As a constant power source, no need for windmills or waterwheels, as you have undead powered wheels
As cities location, make it in the middle of a desert or island in the sea, difficult to leave, or to get to
Water and Power sources are controlled by the government, Rune Circle of endless water, to provide the living with water.
The flow of this can be carefully controlled via water reservoirs, gates etc..
Just thoughts, I'm coming up with for my other thread...
