This is a small town on the outskirts of Dallas. A few blocks from this neighborhood it becomes completely rural. Back when the streets were put in it was a distant commuter town. But there's no potholes in those pictures. Are you referring to others? Though there are really bad streets in some places. Generally seems to happen when the streets are not as needed as they were previously (e.g. urban decay where businesses and people left the area), and the city doesn't have good options about what to do with it. Street parking and walkways are optional things anywhere depending on whether they're useful. More of a dependence on the population density. Really expensive subdivisions often lack them too.
