SOG Used To Reduce Retaining Wall Height
(OP)
I have a retaining wall that was not built per plan and I need to find a way to justify the slab on grade support 1'-0" above the retaining wall footing. I am looking for an ACI section I could use to justify this support. Maybe like a baseplate type calculation. Any help for my response back to DSA would be appreciated today. Thanks!

Sliding should be no problem to justify if it is large enough. Depends upon the sliding coefficient used.
The moment in the wall should be reduced also, receiving support from the slab level.
Create a model showing the slab pushing back on the wall, creating a counter moment to the wall moment and see if you can justify the footing size as constructed. Should work.

And with this new force couple, the slab will have to resist this force couple via flexure in the slab, or axial in the slab on top and shear friction between the slab bottom and top of footing - thus dowels into the top of footing might be warranted.
