Castle Rock, CO
Castle Rock, CO's wildfire risk, in USFS's own numbers
Castle Rock sits at the 96th percentile nationally for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — per USFS's Wildfire Risk to Communities model, built from its 21,883 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Castle Rock at the 95th national percentile — 1 points below its risk-to-structures score, a gap driven by how much is actually built there.
Castle Rock's building exposure, zone by zone
USFS puts 70.8% of Castle Rock's 21,883 buildings in the Indirect exposure zone, versus 22.5% Direct and 6.7% Minimal — a place where the fire doesn't need to reach the structure directly for embers to. At 21,883 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
How Castle Rock compares
Castle Rock's risk sits at a similar level relative to Colorado (84th percentile statewide) as it does nationally (96th) — this place isn't unusual for its own state either way. Among the 31,521 US communities USFS scores, Castle Rock ranks 1,409 for wildfire risk (1 is highest) and 629 by building count (1 is largest). Within Colorado alone, it ranks 75 of 472 places by risk. See the full county-by-county picture for Colorado on its state page.
Castle Rock and the insurance market
At the 96th percentile nationally, Castle Rock carries the very high rating that has pushed some carriers to limit new business in similarly-scored places elsewhere in the country. Worth comparing quotes rather than assuming last year's renewal terms still apply.
What would actually reduce this score
Castle Rock's 70.8% Indirect-exposure share points at embers, not flame contact, as the main pathway — ember-resistant vents and non-combustible roofing rank ahead of defensible space here. Detail in the home-hardening guide.
