I start to build some more stuff on the other side of the river. Everything on this side of the river is going to have tree-lined streets. No expense shall be spared on this part of the land.
It doesn't really matter as I'm playing with infinite funds in any case. The first part of the Norther side of the river houses... houses. There's also some commercial stuff in place, and the flow, design, and logic applied to this area surrounds an enjoyable outcome for citizens.
That enjoyable outcome is low industry (apart from a power plant) - and lots of places to go spend their money. It is also home to a bizarre horseshoe highway bypass, because I can.
