Yes the city of Kansas City in its infinite wisdom required trees to be planted or usually planted them - they got a great deal on trees that grow big, and do it fast and has heaving and cracking driveways and sidewalks all over the city and most of them drop spiny balls all over the place that cause other problems.You should be able to get a tree removed for way less than $10k.You could also epoxy inject and seal if its just cracks, but if it is uneven you might need to do something else.
