Personally I feel like Urban Fantasy has stagnated itself the same way High Fantasy did.
Instead of Elves, Dwarves, and Orcs it has Vampires, Werewolves, Wizards, and Faeries. Now, I love Urban fantasy, but all in all it needs to expand those horizons.(I'm hoping to catch/start that wave wit my novel.) I created a whole new world similar to Earth but with a definitely different history that parallels things to keep development similar. This allowed me to create a large scale magic system unlike anything seen in Urban Fantasy(although based on elements from all over literature, video games, and What have you.) I have urban fantasy in a way I've never seen(High Urban Fantasy basically), and I can only hope that changes the genre and revives it.
Unfortunalty createing worlds like I did is a whole lot more work than Standard Urban Fantasy worldbuilding, especially considering I'm trying to mimic the scope Jim's world feels like it has.
Brandon Sanderson's "The Alloy of Law" pushed this boundary too, but he had an epic fantasy set in the world already to give it credence.
