Looks like an elm

Looks more like a Zelkova

I'm with iochroma.

Zelkova. Somebody needs to remove the staking and ties.

Yes, whatever it is, it looks like it's time to remove the staking. Sometimes companies that are hired to install trees in municipal locations never come back to remove the stakes. I had to take mine out in from of the house. (Zelkova is in the elm family, so maybe you're both right.)
