I just got done demoing a 20yo deck that had no footings or flashing. It was constructed of 2×8's on a 2×10 beam cantilevered. So, my design was to be all 2×10's with a flush beam because the deck is not high off the ground, there is a lot of erosion where the deck was and after I grade it I'm pretty sure there is no room for a beam under the deck framing.
So, anyway, this would call for a 2×10 ledger, the problem is that it would overlap the foundation wall by about 2 inches. I planned on using LedgerLoc screws to attach the ledger board and their min distance for bottom screw is 2 inches I think. But they do say that the ledger board should be no taller than the band joist.
The deck is only about 20 inches off the ground, does anyone see a problem with mounting the 2×10 ledger and proceeding as normal or should I shoot some concrete anchors in the overlapping portion or reengineer the whole design (not preferable)?
Thanks for any info.

It's only a problem to the extent that you're hanging common joists on the unsupported portion of the ledger and therefore relying on the integrity of the woodgrain. If your joist hangers only attach on the upper portion, where the ledger is well attached to the framing, I see no concern.
If your hanger attachment extends lower than that, either anchor to the foundation as well or look for structural hardware that carries the entire ledger from the bottom and mounts to the framing. I've used this one on ICF projects, and it would probably work well without the embedded inner portion and the right screws.
