Santa Rosa Valley, CA
Santa Rosa Valley, CA's wildfire risk, in USFS's own numbers
Out of every US place USFS scores, Santa Rosa Valley lands at the 75th percentile for wildfire risk to structures — well above the national norm for wildfire risk — a figure built from its 2,055 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Santa Rosa Valley's burn probability — fire likelihood with no building count factored in — sits at the 73rd percentile nationally.
Santa Rosa Valley's building exposure, zone by zone
USFS puts 72.3% of Santa Rosa Valley's 2,055 buildings in the Indirect exposure zone, versus 27.7% Direct and 0% Minimal — a place where the fire doesn't need to reach the structure directly for embers to.
