If the trailer is not permitted or in zone (setback) violation it could be interesting.
Zoning really isn't big or enforced in our county.
The trees are getting older, but none are dying, Pretty much ever Leland tree that has fallen was blown over by high winds (with so many, almost guaranteed at least one falls when higher winds come around). For some reason, our particular area is in a area is susceptible to high winds.
In the past, when doing a google search on our road, the old pull along trailer was shown as being right next to the trees (it's really the only place to put something that has level ground). Now, the actual trailer shows up in the image, but talking with another neighbor, they remember when the pull along trailer was put there.
End of the day, I'd have no qualms having all the trees by the trailer removed, however, if I'm being proactive, my honest opinion is we shouldn't have to pay for them all removed.
Perhaps I'd feel differently if when we moved here, I planted the trees next to the trailer when there were none next to the trailer. However, and although I can't prove it, I have a feeling that in the past there was a peeing match between the old homeowner / landowner and an older farmer up the road (we've been told pretty much that as the previous owner and his father didn't get along with this other farmer) put the trailer there to tick off the previous owner of our home. Other farmer has since died and he gave his land to the new guy (who is doing a great job of farming it). However, the trailer as bad as it was in the past looks wise and inside wise, still generates a monthly income for him.
As mentioned, I will do what is legally required on our end.
