When beginning a new city, instead of clicking "New City", click "Load City". Select Frankfurt, Germany and enable the terrain ten up code. The entire city will be gone, although the map will show all the zones, crime, flammability, etc. Then, enable the power to the masses code. You will then have all the power plants. Start building your city. Then, set the speed to "African Swallow" and start the simulation. Wait for a couple years to pass until you get a message stating that the air pollution is low. You will now have a good town with low air pollution and over 3,000,000 simoleons.
