Florida City's Seismic Design Category, explained

Florida City 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. That puts Florida City in the 0th percentile nationally for seismic hazard - higher than 0% of the 4,875 US cities USGS was checked against here.

Florida City by the numbers

The raw figures: peak ground acceleration 0.017g, short-period spectral response 0.038g, 1-second spectral response 0.019g. Among 228 Florida cities in this dataset, Florida City ranks 226 for seismic hazard, the 1th percentile within the state. About 13,157 people live in Florida City, Florida.

What a retrofit costs in Florida City

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Florida. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Earthquake insurance for a Florida City home

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Florida City address.

More on how this number was built

The methodology guide covers exactly how USGS's public design-maps API produced Florida City's numbers. The guide to what a Seismic Design Category actually means covers why a category is never a substitute for an engineer's assessment of one specific house.
