La Porte's Seismic Design Category, explained
La Porte carries Seismic Design Category A under USGS's ASCE 7-16 model. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. Nationally, La Porte ranks above 12% of the 4,875 cities in this dataset for seismic hazard - the 12th percentile.
Where La Porte sits in Texas
USGS's underlying values for La Porte: 0.033g peak ground acceleration, 0.068g at short period, 0.039g at 1 second. Within Texas alone, La Porte ranks 222 of 384 cities by seismic hazard - the 42th percentile in-state. La Porte has a population of about 38,046.
What a retrofit costs in La Porte
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 La Porte 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 La Porte's figures come from
La Porte'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 La Porte.
