RobinD I don't think it's the DOT that does that. I'm not sure which city agency it is. But we had/have a million tree project and they have planted trees where they shouldn't & trees that aren't good for the space. So they will come back and dig up trees without notice. They are also adding their own plantings in some places to try and decrease storm water runoff in areas that flood.
It's like tree-trimming to prevent downed wires. They don't care how the tree looks or even if it is fatally damaged by their cuts. They just do their job.
