Do you really want to (have to) cut down that tree? In many places you
won't have any obligation to do anything if it fell because of natural
causes.

My BIL bought two acres with a creek BED running through it. The water only
flows when it rains. He got his front end loader out and cleaned it up a
lot. It drained a lot better.

His piece of **** neighbor turned him into the state for altering the flow
of a stream. The investigators came and investigated. They commended him
for his work, as it improved flow and he had removed trash. They also
advised him that he SHOULD have asked permission first and gotten a permit.
They fined him $25, the cost of a permit. They said they didn't want to
fine him anything since he had helped the creek flow, and removed dead wood
and trash, but since the neighbor was on paper, and he was technically
wrong, they had to cite him, and did so for the minimum amount.

So, even though you may be thinking of helping someone, remember:

No good deed goes unpunished.

You may get into trouble.

BTW, he now shoots any skunk that comes down there and throws the carcass
onto the neighbor's property. Or just shoots the ones that are already on
the neighbor's property.
