Does Long Beach, CA need an earthquake retrofit?

Under the seismic model IBC and ASCE 7 use for new construction, Long Beach 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. Nationally, Long Beach ranks above 96% of the 4,875 cities in this dataset for seismic hazard - the 96th percentile.

Long Beach by the numbers

USGS's underlying values for Long Beach: 0.711g peak ground acceleration, 1.615g at short period, 0.585g at 1 second. Within California alone, Long Beach ranks 174 of 429 cities by seismic hazard - the 60th percentile in-state. Long Beach has a population of about 450,901.

Retrofit economics for Long Beach

Cripple-wall bracing and foundation bolting - the scope California's Earthquake Brace + Bolt (EBB) grant funds - typically runs $3,000-$7,000 nationally. Every qualifying household gets a $3,000 base grant, which brings that down to $0-$4,000 out of pocket; income-eligible households ($89,040/year or under) can get up to $10,000 total, covering the retrofit outright in most cases.

Insuring against this, not just retrofitting

Long Beach sits in CEA territory, but CEA earthquake coverage is agent-sold only, never direct - so the real first step for a homeowner here is a standard home-insurance quote, then asking that agent about CEA specifically.

Where Long Beach's figures come from

Long Beach's Category D and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. Full Brace + Bolt eligibility rules - beyond what this page can check from a ZIP code alone - are in the retrofit cost and grant guide.
