Does River Oaks, TX need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places River Oaks in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. That puts River Oaks in the 24th percentile nationally for seismic hazard - higher than 24% of the 4,875 US cities USGS was checked against here.

Where River Oaks sits in Texas

The raw figures: peak ground acceleration 0.044g, short-period spectral response 0.093g, 1-second spectral response 0.051g. Among 384 Texas cities in this dataset, River Oaks ranks 134 for seismic hazard, the 65th percentile within the state. About 7,505 people live in River Oaks, 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.

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 River Oaks address.
