Same clay, different decades of settling

Carmel's clay, in plain terms
Crosby-Brookston silt loam and silty clay loam, developed on calcareous till, expands when saturated and shrinks and cracks when dry. That cycle puts steady pressure on foundations across Carmel regardless of when a given house went up.
