Central's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Central 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 Central sits at the 24th percentile for seismic hazard among 4,875 US cities.

Where Central sits in Louisiana

USGS's underlying values for Central: 0.043g peak ground acceleration, 0.089g at short period, 0.059g at 1 second. Within Louisiana alone, Central ranks 17 of 59 cities by seismic hazard - the 72th percentile in-state. Central has a population of about 30,161.

Retrofit economics for Central

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 Louisiana 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 Louisiana.

Earthquake insurance for a Central home

A Central 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 Central's figures come from

Central'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 Central.
