Modeling a Sloped Driveway / Parking Area

[Ed Wachter]

I'd like to model the shape and various slopes of a circular driveway and parking area with a curb/retaining wall around most of the edges. I'd like to use this to verify slope and drainage, cutting sections as needed to check. 

I'm wondering how to approach this and which tools to use:  Maybe add site modifiers and a texture bed to the site model? Or, add some object on top of the site, such as a loft surface, shelled to provide some thickness? Maybe the curb becomes an extrude a long path, or wall? I'm hoping the method will allow easy editing afterward.

Any thoughts on how you would approach this will be greatly appreciated. The attached PDF shows the 2D shape fo the area in question (with the concrete hatch).

Thanks,

Ed
