Leon Valley, TX: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Leon Valley in Seismic Design Category A: Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Nationally, Leon Valley ranks above 5% of the 4,875 cities in this dataset for seismic hazard - the 5th percentile.

How Leon Valley compares

USGS's underlying values for Leon Valley: 0.023g peak ground acceleration, 0.05g at short period, 0.022g at 1 second. Within Texas alone, Leon Valley ranks 347 of 384 cities by seismic hazard - the 10th percentile in-state. Leon Valley has a population of about 11,424.

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 Leon Valley 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 Leon Valley's figures come from

Leon Valley's Category A 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 A does and doesn't tell you about Leon Valley.
