Waveland's Seismic Design Category, explained

Waveland carries Seismic Design Category B under USGS's ASCE 7-16 model. 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 Waveland sits at the 25th percentile for seismic hazard among 4,875 US cities.

How Waveland compares

USGS's underlying values for Waveland: 0.045g peak ground acceleration, 0.092g at short period, 0.057g at 1 second. Within Mississippi alone, Waveland ranks 60 of 61 cities by seismic hazard - the 2th percentile in-state. Waveland has a population of about 7,043.

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 Mississippi 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 Mississippi.

Insuring against this, not just retrofitting

A Waveland 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 Waveland's figures come from

Waveland'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 Waveland.
