Cedar Hill, TX: what USGS's seismic model says

Cedar Hill 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. Nationally, Cedar Hill ranks above 23% of the 4,875 cities in this dataset for seismic hazard - the 23th percentile.

Cedar Hill by the numbers

The raw figures: peak ground acceleration 0.042g, short-period spectral response 0.088g, 1-second spectral response 0.051g. Among 384 Texas cities in this dataset, Cedar Hill ranks 145 for seismic hazard, the 62th percentile within the state. About 49,618 people live in Cedar Hill, Texas.

Retrofit economics for Cedar Hill

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.

What this means for insurance

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 Cedar Hill address.
