Sun Valley, AZ
Sun Valley wildfire risk explained
Sun Valley sits at the 17th percentile nationally for wildfire risk to structures — among the lower wildfire-risk places nationally — per USFS's Wildfire Risk to Communities model, built from its 205 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Sun Valley at the 20th percentile, close to its 17th-percentile risk score.
