I think this thread has gone really off from the original complaint, but I guess I'll address the original complaint. If there are trees in the ROW, in front of your house, even dead, why would you cut them? They aren't your trees, they aren't on your property, they are on County/City/State land/ROW, and they probably have a contractor who is supposed to address them. Call it in, but don't go cutting another property owners trees. Storm drains, once again, that's not your property. Heck, mowing, if you want to, by all means, but someone else is being paid to do it. Yes, there is liability to it, but also, I'm sure wherever you are, there are rules against unpermitted work in the ROW. I know you think you are doing them a favor, but in reality, you probably aren't.
In Florida, on a state road, you are responsible for your own driveway (access), but that state is responsible for mowing, cleaning the culvert (side drain), trimming trees for overhead clearance, removing hazardous trees, fixing shoulder drop offs, ect. And, I'll add, there is a contractor being paid to do it. If it's not being done, it's probably cause they don't know about it. There are thousands of miles of roadway/right of way, and it's not always patrolled well. They really don't want homeowners to be out on a highway cutting trees, cleaning inlets, ect. The homeowners are most likely not using traffic control, probably don't really know what they are doing, and Very well might make a situation worse, and are likely a hazard to themselves and the traveling public.
Also, yes, the person cutting the states tree could be responsible for paying for the tree. Drop a tree on a power line? Bushhog a phone cross box you didn't know was in there? Destroy a fiber hand hole that is covered by grass while trying to grade a drain issue? Heck, drop that dead tree on a traveling car? No thanks.
All that said, yes, I have cut weep holes in the built up grass shoulder of my neighborhood county road, to get the ponding off the road. I also mow the ROW infront of my property sometimes, but I don't go to the effort to make their ditch look like a yard.
