Is there a way I can show both the current topo and the new topo once buildings, driveway, parking added?

Sorry new b question Is there a way I can turn on and off to be able to show the current topo as well as the new topo once buildings, driveway, retaining walls, parking added?

Chief can do only one terrain in a plan.  Do two plans one with current topo one with new.

You can also convert the original terrain to a symbol which will allow you to have both the active terrain and your terrain "symbol" in the same place, but it doesn't retain the contour lines as far as I can tell so it's really only useful for comparing in 3D views.
