Does Canyon, TX need an earthquake retrofit?

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Canyon in Seismic Design Category B: 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 Canyon sits at the 53th percentile for seismic hazard among 4,875 US cities.

Where Canyon sits in Texas

USGS's underlying values for Canyon: 0.09g peak ground acceleration, 0.165g at short period, 0.042g at 1 second. Within Texas alone, Canyon ranks 14 of 384 cities by seismic hazard - the 97th percentile in-state. Canyon has a population of about 16,457.

What a retrofit costs in Canyon

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 Canyon 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 Canyon's figures come from

Canyon'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 Canyon.
