Help removing city tree blocking RV/Trailer parking.

Some pine trees are in the shape of a wedge with the thickest part of the tree basically on the ground.

It's really hard to know which way to go on this one without actually seeing how the tree is interfering with getting the trailer into the back yard. I mean they don't say it's near a driveway, just that it is in the way. Perhaps there's a fence that could be altered? I hate seeing nice trees cut down if there's another way around the situation.
