It has never made sense to me that a neighborhood is responsible for paying for a road that people beyond the neighborhood can use. Portland and Multnomah county work this way and as a result, part of our 1950s neighborhood has a gravel road that's become extremely problematic. The economies of scale make it easier for a city or county to maintain machinery for paving roads and making sidewalks, and yet some municipalities force this on residents. In our case, not everyone in my neighborhood make enough to be able to contribute to the construction of a road, much less repaving.
