We are finishing a driveway on the new property.  So I thought I would ask the "civil" forum for help.

The driveway goes straight back and then has a oval loop.  The loop is 100-125' high.  I found design info on Cul-de-Sac Designs.  Seems the 30' min radii so too small and the 40' radii with center island would work nicely.  I can actually go 50' on the inside.  Getting the 20' lanes down the sides and a wider, say 25', lane on the top is okay.

It is just the tree hugger in me that wants to keep the 40-50' inside radii.  I just don't know if it is enough for the future vehical designs.

The loop island looks so nice now and if I make the inside radii bigger I start taking down 12"+ dia trees that would be in the new back yard... that turns into a back "driveway".

It depends on the length of the truck and the RV.  Typical turning radii for 55 foot long trailer and rig is 50-55 feet.  If the trailer and rig is extra long such as 72 feet I have used turning radii of 65-75 feet.  I believe Architectural Graphics Standards has a diagram for various vehicles corresponding to their lenghts and minimum tutning radii.
