Spring Valley (San Diego), CA
Spring Valley (San Diego) wildfire risk explained
USFS scores Spring Valley (San Diego) at the 94th national percentile for wildfire risk to structures (in USFS's highest wildfire-risk band nationally), a figure built from 8,982 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Spring Valley (San Diego) at the 93rd national percentile — 1 points below its risk-to-structures score, a gap driven by how much is actually built there.
Where Spring Valley (San Diego)'s buildings actually sit
Only 6.5% of Spring Valley (San Diego)'s 8,982 buildings carry Direct exposure and 38.2% carry Indirect; the remaining 55.2% are Minimal, which shifts the risk driving this page's score toward the surrounding landscape rather than any one structure. At 8,982 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.

The disclosure-law guide covers what it requires.
What would actually reduce this score
