I'm not sure what you are classifying as Urban Fantasy if you're including
Mythago Wood, which is certainly a darkish modern fantasy but which steers pretty much clear of anything you could call an urban environment.
But if you are asking for something with a contemporary setting and sensibility, there is always
The War of the Flowers by Tad Williams. Or the Borderland novels and anthologies (various authors), edited by Terri Windling.

In fact, you might want to have a look around the Endicott website in general, since a lot of the books they recommend there are Urban Fantasy.
You might also want to look into Tim Powers and James Blaylock, although they both write other types of fantasy as well.
