From my understanding, there's nothing saying that Culdesac residents can't park on public street parking, it's just that the development doesn't have any street parking. So that case (which was about restricting access to existing street parking) doesn't seem relevant. Unless you're claiming that the 14th amendment would require the developer to include street parking? But that seems like quite a stretch.
