Local housing stock
Only 32.9 percent of the housing here went up after 1989; the median construction year is 1980. A 1980 median of frame on slabs and crawlspaces, 67 percent standing before 1990, mixing older valley grid with later tracts — including Coffey Park's post-fire rebuild — on creek alluvium.
Climate & seasonal risk
December alone accounts for 20.5 percent of the 31.53 inches this area sees in an average year, on 1991–2020 normals recorded 0.8 miles away at SANTA ROSA. December's 6.47 inches is a winter-river peak, a fifth of the year in one month. Creek alluvium takes it fast, then the Russian River system holds the table. Older crawlspaces stay wet through the fog that follows; the rebuilt slabs fail at grade and at irrigation the rest of the year.

- Russian River system holding the table up under the older grid after the peak month
