Okay, should have done this in the first place. I've narrowed it down A LOT...I can request more than 1 and get a 1st, 2nd and 3rd choice so which would be your top 3?

Oh yeah, the property is 40' wide and houses are close to the sidewalk...very Brooklyn/Queens looking.

7 Locust Shademaster
8 Greenspire Linden
10 Northern Red Oak
12 Pin Oak
13 Silver Linden
15 Sweet Gum
18 Japanese Zelkova

If the houses are close to the Sidewalk any of the oaks may get to large. I would likely go with a Zelkova cultivar called 'Green Vase' It is suppose to be fast growing and vase shaped which should work well in your location. From what I have been told seed grown trees can be variable as to size and shape. David

Unless you can get a non-fruiting one, I would skip the Sweetgum - the "gumballs" are a royal pain to clean up. And an even more royal pain to step on with bare feet! Or bump into with bare hands while weeding under them.

While I do like oaks, if there is no more than 40' of space, the oaks will probably get too large over time.

I would go with the Locust, either of the lindens, and then the zelkova. I have no direct experience with any of them, so am going by what I have seen in photos or with related trees. I liked the locusts growing at my sister's then-house in WA years ago - the flowers were nicely scented. And linden flowers are reputed to be very nice, also. Zelkova flowers are pretty inconspicuous to my knowledge.
