What we see in Rancho Cucamonga
Serving Rancho Cucamonga and the surrounding area, including Etiwanda Heights Town Center, Alta Loma.
Local housing stock
Only 44.4 percent of the housing here went up after 1989; the median construction year is 1988. Stucco on slabs and short stem walls, a 1988 median spread from the fan up onto the Alta Loma benches, much of it with no later drain between splash and plate.
Climate & seasonal risk
The nearest long-term record — RANCHO CUCAMONGA 1.6 W, 1.9 miles out — puts the annual normal at 17.2 inches, with February heaviest at 5.16. February's 5.16 inches is a winter flash in a 17-inch year. On the fan that rain arrives as debris-laden sheet flow the debris basins only partly catch; on the benches it sheets off decomposed granite. Citrus laterals keep one edge of many pads wet through the dry months, so the February pulse hits ground that never reset.
Common moisture and mold problems in Rancho Cucamonga
- Cucamonga Canyon and Day Creek flashing February rain across the alluvial fan faster than street inlets can take it
- Alta Loma citrus laterals holding a moisture gradient under 1980s slabs through the long dry season
- Debris basins filling with granite so a later cell sheets around them onto downhill pads
- Alta Loma stucco with no stem, so a February flash off Cucamonga granite wets the bottom plate at splash
