Maumelle's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Maumelle is Category D. High seismic hazard - this is the category most of coastal California, the Pacific Northwest, and other active fault regions fall into. Code mandates significant seismic detailing and restricts irregular structural configurations. This is the category the Brace + Bolt scope (cripple-wall bracing, foundation bolting) is built for. Rank it against the rest of the country and Maumelle sits at the 83th percentile for seismic hazard among 4,875 US cities.

Where Maumelle sits in Arkansas

The raw figures: peak ground acceleration 0.226g, short-period spectral response 0.404g, 1-second spectral response 0.15g. Among 68 Arkansas cities in this dataset, Maumelle ranks 25 for seismic hazard, the 64th percentile within the state. About 19,541 people live in Maumelle, Arkansas.

Bracing and bolting: the actual cost

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

Earthquake insurance for a Maumelle 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 Maumelle address.
