An extension of http://community.simtropolis.com/files/file/31350-simmasters-extra-cheats-dll/ that adds four new cheats (zonemilitary, zonespaceport, zoneairport, zoneseaport), which invokes the zoning tools for their respective unimplemented zones. Nothing grows in them by default since the game's tract and port developers don't bother with them, so it's not terribly useful.
