Ridge and Valley. Limestone residuum in the valleys, sandstone on the ridges, karst
Limestone valleys mean karst: permeability is excellent until it is not. Sinkhole activity is an underrated cause of foundation failure here.

Water peaks in April and May with the spring rains. The dry late summer is when soil movement shows up instead, so the two problems take turns.

Questions about Hanover
Is the soil the same everywhere in Hanover?
No. These values describe York County as a whole, which is the unit the soil survey publishes. Within a city, map units change over a few hundred metres — the soil map draws the actual polygons around a point and is the honest answer for one address.
