As you can see from the photo, there is damage to the left side of the wall, where a tractor-trailer fell off the wall and damaged. I had just witnessed several nieghbors and tried to drive the truck, but he continued.

I'd inspect my property for the first time, I bought 3 years ago. My property is found in the grass. The sidewalk and the wall is part of the city. Can the city to fix the problem or that I intended to keep it, since it in front of my property?
