It is more often a design consequence than a defect. Split-levels have foundation walls that meet grade at several different elevations, and each of those step points is a joint that has to keep water out while soil pressure changes across it. Those joints are where water most commonly appears in this stock. Sealing the joint from inside rarely holds; managing where the water arrives at the outside face is what works.

Tropical remnants. Systems that come ashore to the south still carry enough moisture this far inland to produce very large single-day rainfall totals in late summer and early autumn. That skews the monthly record toward October in a way that has nothing to do with ordinary thunderstorm season. Practically it means the biggest test of a drainage system here usually arrives once a year in a single event rather than repeatedly.

It varies considerably across short distances, and it matters a great deal. Where weathered rock is close to the surface, the soil above it has limited capacity to store water, so it fills quickly and then moves sideways along the rock. That lateral flow arrives at whatever is in its path, which is often a basement wall. It also explains why one lot on a street drains for days and the neighbor's floods in hours.
