Seattle
It’s Seattle, but without any civilization. I gave you plenty of customs houses to get started, but you should use air and water for trade as well. There is an island (Mercer Island) with some richer resources. Lots of hills and peninsulas, but still flat land throughout the map. I widened the Freemont Cut (that northern canal thing) and the Duwamish Waterway (that south riverish thing) to just over 100 meters across to make shipping by boat easier. Let me know if there are any problems that I can fix.
