Vidor's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Vidor is 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 Vidor sits at the 20th percentile for seismic hazard among 4,875 US cities.

Where Vidor sits in Texas

USGS's underlying values for Vidor: 0.039g peak ground acceleration, 0.079g at short period, 0.046g at 1 second. Within Texas alone, Vidor ranks 171 of 384 cities by seismic hazard - the 56th percentile in-state. Vidor has a population of about 9,686.

What a retrofit costs in Vidor

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.

Earthquake insurance for a Vidor home

A Vidor 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 Vidor's figures come from

Vidor'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 Vidor.
