How do I make a double curved surface for this driveway? It is a sloping sidewalk I need to match up with a flat basement floor.

I sloped a floor on one end, but the lower end is too high because the sidwalk slopes down close to the level of the garage.

If I slope a triangle up in the blue, the long sides don't match up with both the sidewalk and the other half of the driveway.

I tried an in place model, but the sweep, extrusion, or other things don't seem like they will work.

Because of double slope and curved surfaces, traditional modeling is not appropriate for site surfaces.  In the last post in this: https://www.revitcity.com/forums.php?action=viewthread&thread_id=42137 I have a link to a process I have been doing for a long time.  It will not give you thickness but the surface will be correct.  You would have to add detail components for and section views for thickness.
