I have seen quite a few sidewalks that are in great need of repair, but somehow the city doesn't seem to see a need for it. I see elevated parts of sidewalks that can pose a serious threat to people who are walking and not paying attention. They could trip on that elevated part and fall right on their face.
Those spots could be smoothed out so that they won't be such a hazard to everyone that walks on them. Broken sidewalks are just as bad as potholes in roads are for cars. The only difference is that, while the potholes can cause major damage to cars, the sidewalks can cause major damage to humans.
