Parker, TX: what USGS's seismic model says

Parker 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, Parker ranks above 33% of the 4,875 cities in this dataset for seismic hazard - the 33th percentile.

How Parker compares

The raw figures: peak ground acceleration 0.055g, short-period spectral response 0.112g, 1-second spectral response 0.058g. Among 384 Texas cities in this dataset, Parker ranks 59 for seismic hazard, the 85th percentile within the state. About 6,332 people live in Parker, 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.

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 Parker address.
