Lampasas's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Lampasas is 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 Lampasas sits at the 8th percentile for seismic hazard among 4,875 US cities.

Where Lampasas sits in Texas

USGS's underlying values for Lampasas: 0.025g peak ground acceleration, 0.054g at short period, 0.035g at 1 second. Within Texas alone, Lampasas ranks 321 of 384 cities by seismic hazard - the 16th percentile in-state. Lampasas has a population of about 7,936.

What a retrofit costs in Lampasas

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 Lampasas home

A Lampasas 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 Lampasas's figures come from

Lampasas'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 Lampasas.
