Plantation, FL: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Plantation 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 Plantation sits at the 2th percentile for seismic hazard among 4,875 US cities.

How Plantation compares

USGS's underlying values for Plantation: 0.02g peak ground acceleration, 0.044g at short period, 0.022g at 1 second. Within Florida alone, Plantation ranks 185 of 228 cities by seismic hazard - the 19th percentile in-state. Plantation has a population of about 100,694.

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 Florida 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 Florida.

Insuring against this, not just retrofitting

A Plantation 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.
