I haven't been following very closely, but there is a snappy program called
"Florida Pier NT v1.59" for substructure embedment
at http://www.dot.state.fl.us/structures/ Perhaps the modeling will enhance your considerations.

Subject: RE: FLAG POLE FOUNDATIONS in CA
Let me clarify "foundation"... I really need the correct approach for the
pier design....the manufacturer's provide their own design which typically
involves embedding the pole into a corrugated tube which is then filled
with sand. The corrugated tube is placed in approx. 3'-0"x12"dia of
concrete (unreinforced?). I am concerned that this support may not be
sufficient...the numbers that I ran for the UBC criteria required a pier
embedment of about 15 feet!....
Thank you for the input...
