You can add parking spaces to a toposurface and define the toposurface as the parking component’s host.
You can also use subregions to create road elements. See Create Toposurface Subregions.

  When you use the Pick Host tool, you are deliberately setting the parking component on top of the toposurface. If you move the parking component around on the toposurface, it remains attached to the toposurface.
