That's what has worried me in the past, not settlement but a slender poorly footed pier to grade on solid ground with loose fill around its' tube and an eccentric post placement at the hinge between pier and post. I try to talk clients into running the posts down to the footing to avoid that hinge and potential lateral problem. I noticed in Papio's version that this is prohibited and am curious about the reasoning. BTW it is showing the ledger lags above the joist hangers, tension perp failure, I've seen pics of that deck on the ground with lags and the top of the ledger still on the building.
Those of you requiring a larger diameter pier, is it for footing size or lateral resistance?
