While I find most of it agreeable (or as I have told advocates, it won’t change what it is in my boulevard). (Item #46, DOC; PS_O) The section regarding mailboxes, especially ones that are more permanent (like brickwork) may be a little concerned. As I understand it as I read it below (I think) if a utility company, or the city destroys your structure, you are responsible for the loss, and it also looks like you won’t be able to replace it like it was.
I totally understand in an emergency situation, but if it is scheduled work, there is no reason these cannot be preserved.
