Frequently asked questions
The lot was graded flat and it still ponds in February. Why?
The fill is the reason. Ground near the airport and the warehouse blocks was built up to make level pads, and that fill perches a February burst instead of passing it into the cobble underneath. The water then stands against whatever sits at the toe of the pad, which is usually the older housing. Flat is not the same as draining, and on a fan the two are often opposites.
A short wet season on the fan. How does a 1980 slab still wick in February?
Because February is a quarter of the year, and the covering has been baking since April. Gaps that were tight in November take the first flash on the fan. A dry climate does not stay sealed; it opens and then soaks all at once.
Cucamonga is boxed in concrete. How is there still water under the pad?
The box took the surface. It did not take the cobble. Cucamonga alluvium still carries underflow beside the lining, and a 1980 pad on that gravel wets from below with no overtopping. Looking at the channel walls will miss the job under the floor.
