Christiana, PA
Christiana wildfire risk explained
USFS's Wildfire Risk to Communities model puts Christiana at the 9th national percentile for risk to structures, among the lower wildfire-risk places nationally — a score built from 426 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Christiana's burn probability — fire likelihood with no building count factored in — sits at the 8th percentile nationally.
What "at risk" means for the buildings here
62% of Christiana's 426 buildings fall in USFS's Indirect exposure zone — ember cast rather than direct flame — against 37.3% Direct and 0.7% Minimal. Vent screens and roofing material matter more here than lot clearing alone.
How Christiana compares
Christiana scores 9th nationally and 6th within Pennsylvania — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Christiana ranks 28,853 for wildfire risk (1 is highest) and 18,735 by building count (1 is largest). Within Pennsylvania alone, it ranks 1,874 of 1,991 places by risk. See the full county-by-county picture for Pennsylvania on its state page.
Christiana and the insurance market
Christiana's low wildfire rating (9th percentile) isn't the kind of score driving the carrier pullback making news in the highest-risk Western markets — but a standard homeowners quote is still worth comparing on its own terms.
Hardening a home in Christiana
With ember exposure the dominant pattern in Christiana (62% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
