Levelland's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Levelland 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 Levelland sits at the 13th percentile for seismic hazard among 4,875 US cities.

How Levelland compares

The raw figures: peak ground acceleration 0.035g, short-period spectral response 0.076g, 1-second spectral response 0.03g. Among 384 Texas cities in this dataset, Levelland ranks 214 for seismic hazard, the 44th percentile within the state. About 12,494 people live in Levelland, Texas.

Retrofit economics for Levelland

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.

Earthquake insurance for a Levelland home

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 Levelland address.

More on how this number was built

The methodology guide covers exactly how USGS's public design-maps API produced Levelland's numbers. The guide to what a Seismic Design Category actually means covers why a category is never a substitute for an engineer's assessment of one specific house.
