Update;
a utility engineer is involved! so most likley i will assume a position of being told , not figuring myself, the end result.

this is a high end retirement cul-de-sac neighborhood, no mobile homes allowed!

I will post the engineer's spec's when i receive them, if only to make a comparative anaylisis to the NEC.

meanwhile i shall do my best Forrest Gump with the 'manual backhoe' in the ditch...
