Lincoln City's Seismic Design Category, explained

Lincoln City 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 Lincoln City sits at the 95th percentile for seismic hazard among 4,875 US cities.

Lincoln City by the numbers

USGS's underlying values for Lincoln City: 0.655g peak ground acceleration, 1.322g at short period, 0.684g at 1 second. Within Oregon alone, Lincoln City ranks 7 of 80 cities by seismic hazard - the 92th percentile in-state. Lincoln City has a population of about 10,034.

What a retrofit costs in Lincoln City

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 Oregon 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 Oregon.

Earthquake insurance for a Lincoln City home

A Lincoln City 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.
