Does Center, TX need an earthquake retrofit?
Center carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Rank it against the rest of the country and Center sits at the 28th percentile for seismic hazard among 4,875 US cities.
Where Center sits in Texas
The raw figures: peak ground acceleration 0.048g, short-period spectral response 0.098g, 1-second spectral response 0.06g. Among 384 Texas cities in this dataset, Center ranks 103 for seismic hazard, the 73th percentile within the state. About 5,231 people live in Center, Texas.
Bracing and bolting: the actual cost
Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Texas. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.
Earthquake insurance for a Center home
Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Center address.
