Frequently asked questions
Why does the wet season here feel continuous rather than event-driven?
Because it is. Rather than a few large storms, this climate delivers steady rain across the dark months, and the ground never dries out between events. That changes the problem entirely: instead of managing a peak, you are managing a soil that stays saturated for months. Anything that depends on drying out between wettings does not get the chance.
What is the hardpan and why does it matter so much?
It is a dense layer of glacially compacted till, and it is close to impermeable. Water soaking down through the looser soil above reaches it and stops, then travels sideways along its surface following the slope. That is why a foundation cut into a plateau edge takes water at the uphill face: it is sitting across a flow that is moving above the hardpan, not through it.
Most housing here is newer. Does that make it lower risk?
It generally means better detailing, and on this ground the detailing matters. But newer construction here also went onto the harder sites, including plateau margins and slopes that earlier building avoided. A well-drained modern foundation on a steep till slope in a five-month wet season is not obviously safer than an older house on flat ground.
