Mexia's Seismic Design Category, explained

Mexia 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. Rank it against the rest of the country and Mexia sits at the 18th percentile for seismic hazard among 4,875 US cities.

Where Mexia sits in Texas

USGS's underlying values for Mexia: 0.035g peak ground acceleration, 0.074g at short period, 0.047g at 1 second. Within Texas alone, Mexia ranks 192 of 384 cities by seismic hazard - the 50th percentile in-state. Mexia has a population of about 6,916.

Bracing and bolting: the actual cost

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by Texas specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in Texas.

What this means for insurance

A Mexia homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.

Where Mexia's figures come from

Mexia's Category B and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category B does and doesn't tell you about Mexia.
