Just wondering, is the crack on the trunk facing south-west? I'm wondering if it is a frost crack and, just to throw another possibility out there, could it have been a maple? The City was apparently taking maples out as well as EAB ashes (saw that somewhere but would have to find it again). Maples are prone to frost cracks (so are horse chestnut), and some lists include elm as susceptible too although I don't recall seeing it on an elm around here. I see it on young maples though A picture of young maple architecture:

There are other maples on the street. Whether they were still planting them prior to 2007 I have no idea.
Edited to add: It's hard to see the branch let alone leaf arrangement on the ID tree, but I see a couple of places where it looks opposite. That would rule out elm.
