Corona, SD
How exposed is Corona to wildfire?
Out of every US place USFS scores, Corona lands at the 14th percentile for wildfire risk to structures — among the lower wildfire-risk places nationally — a figure built from its 111 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Corona at the 12th percentile, close to its 14th-percentile risk score.
Where Corona's buildings actually sit
Only 27% of Corona's 111 buildings carry Direct exposure and 0% carry Indirect; the remaining 73% are Minimal, which shifts the risk driving this page's score toward the surrounding landscape rather than any one structure.
Where Corona ranks
Corona scores 14th nationally and 1st within South Dakota — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Corona ranks 27,117 for wildfire risk (1 is highest) and 28,609 by building count (1 is largest). Within South Dakota alone, it ranks 437 of 439 places by risk. See the full county-by-county picture for South Dakota on its state page.
Corona and the insurance market
Corona's low rating (14th percentile nationally) sits outside the range where wildfire risk alone reshapes an insurance market — still, a homeowner here loses nothing by comparing rates.
Hardening a home in Corona
Corona's 73% Minimal-exposure share means structure-level hardening matters less here than it would elsewhere — still worth the low-cost basics, per the home-hardening guide.
Where Corona's figures come from
Corona's 14th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. The exposure-zones guide covers what Corona's dominant minimal exposure actually means, with real examples from across the dataset.
