Monroeville's Seismic Design Category, explained

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Monroeville in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Monroeville ranks above 33% of the 4,875 cities in this dataset for seismic hazard - the 33th percentile.

Where Monroeville sits in Alabama

The raw figures: peak ground acceleration 0.055g, short-period spectral response 0.115g, 1-second spectral response 0.069g. Among 107 Alabama cities in this dataset, Monroeville ranks 81 for seismic hazard, the 25th percentile within the state. About 5,720 people live in Monroeville, Alabama.

Bracing and bolting: the actual cost

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

Earthquake insurance for a Monroeville 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 Monroeville address.
