Everything technical you have written seems reasonable and correct.

I can't comment much on cost because construction costs are VERY site specific. I would expect, however, that the marginal cost difference between the "el cheapo" foundation and a good foundation is likely to be very small compared to the possible cost of correcting problems resulting from a bad foundation design.

Daryl, in Anchorage the minimum depth for cold footings that are part of a structure is 60" (bottom of footing). For isolated foundations (light poles, etc.) and cast-in-place concrete piers it is 120" unless it is non-frost susceptible soils where 60" is allowed. I am concerned
