There are places in the US, that when you buy a house or property, you are given a choice. You can build a sidewalk for it yourself, or you can pay the city/county for a sidewalk.
The thing is, if you pay the city/county for the sidewalk, they stipulate that they can build that sidewalk where ever they want. This does not have to include in front of, or anywhere near, your house
The US is a very strange place.
