North Ogden's Seismic Design Category, explained

North Ogden carries Seismic Design Category D under USGS's ASCE 7-16 model. 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 North Ogden sits at the 95th percentile for seismic hazard among 4,875 US cities.

How North Ogden compares

USGS's underlying values for North Ogden: 0.679g peak ground acceleration, 1.49g at short period, 0.552g at 1 second. Within Utah alone, North Ogden ranks 10 of 95 cities by seismic hazard - the 90th percentile in-state. North Ogden has a population of about 22,908.

What a retrofit costs in North Ogden

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by Utah specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in Utah.

What this means for insurance

A North Ogden homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.

North Ogden's Category D and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category D does and doesn't tell you about North Ogden.
