So, are they using that 60 foot easement for profit? Hmmmm.
It is perfectly legal to make profit off land that has an easement. For instance I have some land that has an easement on it to allow access to a parcel of land that is used to grow trees for lumber. About every ten years they go in and re-clear the access road and make a timber cut. The timber cut takes about a month and then they leave for another 10 years. I knew about the easement when I bought the land and it has been a win win. The timber owners have land that is protected from lumber thieves because of limited access (They always call and make arrangements months before re-opening the road, so if anyone tries to reopen the road, I will know that someone is attempting unauthorized access.). And I have land that abuts my property that will remain undeveloped; which is what I want.
We have adjusted the easement, so the road has been moved to a route that I can use a portion. They like the idea, because they would only have to clear a shorter portion on future timber cuts and I like it because they paid for making me a road that I wanted. Therefore I have "profited" from the easement.
