If that bothers you, don’t buy property adjacent to 200ft tall trees. They will fall. That’s what trees do. They grow, then die and fall over.
It feels like the top commenter is simply sharing personal insight, not recriminating and pleading woe, so Idk why these responses act like they're being egregious. The situation simply requires cooperation with a government that apparently is loathe to go through the process with.
And if it’s your fence you can build one of the ones that’s cheap and easy to replace. I wouldn’t be shocked if you could put chain link back up after some straightening. You could use the downed tree to fix the fence if it was split log (not so good at keeping dogs in though)
