text: Interestingly enough, the guidance photo for "Paved (generic)" in StreetComplete looks like oil-bound macadam, which is sometimes considered a "nondurable surface," which sounds like "unpaved" to me. I know there have been big uproars here in Seattle when the city promised to pave neighborhood streets, and renewed the oil-bound macadam instead. That may be when they started covering the oil with the light layer of crushed stone and rockdust.
