New Feature Copying contours

I have made my existing surface successfully. The new features surface i made with the new proposed elevation was imported successfully but the CAD drawings received never had the contours entered so i took the time and manually entered all the contours and elevation points.
I have multiple varying surface elevations for example the pond and ROW cuts and fills will be to plans minus the topsoil strip, however the road will be a -18" level. Unless i am wrong i need to make another featured surface for this varying level.
I do not want to have to manually re enter all the new contours. 
Is there a way to copy the contours and points from one featured surface to the next?

Any help would be much appreciated.
Thank you,
Nick
