Does North Bend, OR need an earthquake retrofit?

USGS's ASCE 7-16 seismic model can't even fit North Bend onto its standard code table - ground motion here (peak ground acceleration 0.809g) is past what the table covers, which under §11.4.8 means a site-specific geotechnical study, not a standard letter grade. That puts North Bend in the 99th percentile nationally for seismic hazard - higher than 99% of the 4,875 US cities USGS was checked against here.

Where North Bend sits in Oregon

USGS's underlying values for North Bend: 0.809g peak ground acceleration, 1.613g at short period, 0.818g at 1 second. Within Oregon alone, North Bend ranks 3 of 80 cities by seismic hazard - the 97th percentile in-state. North Bend has a population of about 10,049.

What a retrofit costs in North Bend

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 North Bend home

A North Bend 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.

Where North Bend's figures come from

North Bend's Category rating 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 does and doesn't tell you about North Bend.
