Lago Vista, TX: what USGS's seismic model says

Lago Vista carries Seismic Design Category A under USGS's ASCE 7-16 model. 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 Lago Vista sits at the 6th percentile for seismic hazard among 4,875 US cities.

Where Lago Vista sits in Texas

The raw figures: peak ground acceleration 0.024g, short-period spectral response 0.052g, 1-second spectral response 0.03g. Among 384 Texas cities in this dataset, Lago Vista ranks 337 for seismic hazard, the 12th percentile within the state. About 10,201 people live in Lago Vista, Texas.

What a retrofit costs in Lago Vista

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.

Insuring against this, not just retrofitting

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 Lago Vista address.
