Sitting on bedrock changes the diagnosis
Where dolomite runs close to the surface, a Joliet foundation can behave differently than one on deep till a few blocks over -- so the fix has to account for how much cushioning till actually sits between the footing and the rock, not just apply a standard settlement remedy.

Joliet's ground, house by house
Quarrying between Joliet and Lemont exposed roughly 25 sites' worth of dolomite by the 1890s, and that bedrock still lies close under much of the city today. Till depth over it varies enough lot to lot that settlement patterns rarely look the same on two adjacent properties.
