Do you know what species the tree is? Looks like maybe a liquid amber?

If you can determine that and research their root pruning susceptibility that could help you decide where to go with it. Planting any tree near concrete or turf without root barrier will lead to surface roots instead of deep ones resulting in lifting things.

I realize you did not plant the tree, but after root pruning installing some root barrier might help moving forward. If it is a liquid amber they are notorious for invading joints, crushing and creating havoc with bell and spigot clay sewer pipe. If your waste line is close to that tree that will be the next issue. A few square feet of new concrete will be cheaper than a new sewer lateral..
