King City's Seismic Design Category, explained

King 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. Nationally, King City ranks above 87% of the 4,875 cities in this dataset for seismic hazard - the 87th percentile.

Where King City sits in Oregon

USGS's underlying values for King City: 0.384g peak ground acceleration, 0.841g at short period, 0.392g at 1 second. Within Oregon alone, King City ranks 39 of 80 cities by seismic hazard - the 52th percentile in-state. King City has a population of about 5,002.

Retrofit economics for King 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 King City home

A King 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.
