Brooklyn Center, MN: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Brooklyn Center in Seismic Design 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 Brooklyn Center sits at the 6th percentile for seismic hazard among 4,875 US cities.

Brooklyn Center by the numbers

The raw figures: peak ground acceleration 0.023g, short-period spectral response 0.048g, 1-second spectral response 0.029g. Among 155 Minnesota cities in this dataset, Brooklyn Center ranks 53 for seismic hazard, the 66th percentile within the state. About 31,755 people live in Brooklyn Center, Minnesota.

What a retrofit costs in Brooklyn Center

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

Earthquake insurance for a Brooklyn Center 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 Brooklyn Center address.
