As Dan points out, 250.52(A)(3) specifies several installation requirements in
order for a concrete encased electode to qualify as a permitted Grounding
Electrode. A pole mount foundation would certainly qualify if it met those
requirements.

Even if the requirements are not met, IMHO, any opportunity to inexpensively
increase the grounding integrity of a system should not be overlooked,
particularly in lightning country. Of course, a code compliant Grounding
Electrode System is still required. Bonding a non compliant, but never the less,
very substantial additional "electrode" to that system would not hurt anything
and quite possibly help considerably.
