I'm having a Silver Maple taken out and want something to put in it's place. I'd like some ideas. Here is my wish list for a tree:

Grows relatively fast
Keeps a compact shape
Pretty Flowers
Not too much pollen
No nuts
No feeder or surface roots - well behaved root wise in that it won't mug my sewer system
Grows around 30 - 50 feet
Leaves change color in Fall
Drops leaves in Winter (and leaves are good for mulching)

The picture is what's coming out.

I realize that I probably can't have everything on my wish list, but the bolded wishes are a must.

So give me some ideas for a tree good for my zone and if you have a picture of a mature one, please post it.

Thanks!
