It turns out, the sidewalk had settled a lot in the past 50 years, I mean big time, and instead of taking out the sidewalk and fixing the settlement issues with the hillside, they previous owners had simply kept pouring more and more concrete on top to level it off! The last 8 ft of the sidewalk was 16 inches thick. No, I'm not exaggerating.

Clearly you screwed up by starting at the wrong end.
