Here's a city overview map I made for my ICONS Superpowered Roleplaying Game campaign setting, Grimm City. I used the Modern Road Map templates from the 2011 Cartographer's Annual Volume 5 for CC3. Eventually I hope to expand this into a fully-developed street level map. And If you are interested in this sort of thing or enjoy supers RPGs, I'll be developing Grimm City as a campaign setting for ICONS on my blog, JUST ADD HEROES.
