Blown up my town but no idea how to rebuild -help

When I nuked my town I started off by building the neighborhood/housing part which I like closer to the beach area and mountains. After that I just started adding the buildings that I thought would be closer to the houses like the schools. I put the town hall in the center of town then the police station, hospital ect behind the town hall. It is very time consuming. Good luck. I am considering nuking again.
