You can download a height map file from https://terrain.party/ or https://heightmap.skydark.pl/ and start a new game with the unlimited money cheat. Then it's just a matter of placing roads, utilities, public services and zoning the rest (that's the fun part).

Sadly, the height maps and the OSM road imports were quite borked, so I just ended up doing all the roads by hand with the maps on a second monitor. Some screenshots of the process here: https://github.com/team-watchdog/colombo-skylines/wiki/Intro...
