Local housing stock
Of roughly 35,919 housing units, about 32,578 were finished in 1989 or earlier, which puts the median construction year at 1959. Post-war stucco on slabs, a 1959 median with more than nine in ten units standing before 1990, packed onto Rio Hondo alluvium with no stem wall between splash and plate.
Climate & seasonal risk
Downey averages 15.18 inches of precipitation a year on the 1991–2020 normals, taken at WHITTIER 2.9 WNW 5 miles away, with February the wettest month at 4.64 inches. February's 4.64 inches is a winter flash in a 15-inch year. On this rancho that rain arrives as a Hondo pulse the Narrows already concentrated; a 1959 slab poured as if the wash had left still takes the month from below.
Common moisture and mold problems in Downey
- Rio Hondo flashing February rain across rancho alluvium faster than street inlets can take it
- Whittier Narrows concentrating the same cell onto 1950s pads the channel only partly contains
- Rancho stucco with no stem, so a February Hondo pulse from Whittier Narrows wets the bottom plate at splash
- 1959 Hondo slabs hiding a Whittier Narrows pulse until a garage slab sweats along the channel side
