About these rancho cucamonga water risk guides
Water damage in this valley is not generic. The failures that fill our schedule are products of local geology, local water chemistry and local weather, and they are predictable enough to plan around.
Three patterns account for most of it. Copper installed through slabs in the 1970s through 90s is now deep into pinhole corrosion in water that has been working on it for decades — which is why slab leaks dominate the older tract neighbourhoods. Santa Ana winds lift roof tile in October, the opening sits dry through a rainless autumn, and the first atmospheric river in December finds it. And a year's rain arriving in five months lands on drainage that has silted up over eight dry ones.
These guides map those patterns onto specific areas, from the foothill wind corridor to the expansive clay soils in south Fontana, so the risk can be read against your own street rather than a national average.
