Tree recommendation for front yard, large, med/fast grower
Looking for a recommendation for my front yard(see below, zone 6). There used to be a large maple on this side of the house that died a few years ago. You can probably see the newer circle of sod in the center of the pic. There's 40 feet between the sidewalk and my house and my neighbors drive is on the left side as well. The easement has 2 medium white ash (i think) trees on it now as well. I also already have a river birch on the right side. I think a weeping willow would look great but from what I've read they need more room to grow. Just looking for thoughts, comments, suggestions, maybe another river birch to balance out the look? Will there be any issues with planting where an old tree used to be recently?
