Miramar, FL: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Miramar in Seismic Design Category A: Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. That puts Miramar in the 2th percentile nationally for seismic hazard - higher than 2% of the 4,875 US cities USGS was checked against here.

How Miramar compares

The raw figures: peak ground acceleration 0.02g, short-period spectral response 0.043g, 1-second spectral response 0.021g. Among 228 Florida cities in this dataset, Miramar ranks 181 for seismic hazard, the 21th percentile within the state. About 143,242 people live in Miramar, Florida.

Retrofit economics for Miramar

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 Miramar 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 Miramar address.
