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

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Liberty Hill in Seismic Design Category A: Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Rank it against the rest of the country and Liberty Hill sits at the 8th percentile for seismic hazard among 4,875 US cities.

Liberty Hill by the numbers

The raw figures: peak ground acceleration 0.025g, short-period spectral response 0.053g, 1-second spectral response 0.034g. Among 384 Texas cities in this dataset, Liberty Hill ranks 320 for seismic hazard, the 17th percentile within the state. About 11,984 people live in Liberty Hill, Texas.

What a retrofit costs in Liberty 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 Liberty Hill address.
