Serving Downey and the surrounding area, including Hollydale, Orange Estates.
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
