Sunnyvale, TX
Sunnyvale wildfire risk explained
Sunnyvale sits at the 66th percentile nationally for wildfire risk to structures — well above the national norm for wildfire risk — per USFS's Wildfire Risk to Communities model, built from its 3,446 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 Sunnyvale at the 66th percentile, close to its 66th-percentile risk score.
Sunnyvale's building exposure, zone by zone
USFS puts 43.1% of Sunnyvale's 3,446 buildings in the Indirect exposure zone, versus 35.8% Direct and 21.1% Minimal — a place where the fire doesn't need to reach the structure directly for embers to.
How Sunnyvale compares
Sunnyvale ranks lower within Texas (23rd percentile statewide) than its 66th national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Sunnyvale ranks 10,792 for wildfire risk (1 is highest) and 4,851 by building count (1 is largest). Within Texas alone, it ranks 1,393 of 1,795 places by risk. See the full county-by-county picture for Texas on its state page.
Sunnyvale and the insurance market
Sunnyvale's 66th-percentile, high rating is the kind of score behind a broader national pattern: insurers pulling back from the highest wildfire-risk markets, non-renewing or declining new policies outright, most visibly in California. Shopping around, not assuming automatic renewal, tends to matter here.
What would actually reduce this score
With ember exposure the dominant pattern in Sunnyvale (43.1% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
