Marysville's Seismic Design Category, explained

Under the seismic model IBC and ASCE 7 use for new construction, Marysville is Category C. Moderate seismic hazard. Code adds irregular-building restrictions and requires bracing of some nonstructural components (e.g. tall shelving, water heaters) in addition to structural detailing. That puts Marysville in the 78th percentile nationally for seismic hazard - higher than 78% of the 4,875 US cities USGS was checked against here.

How Marysville compares

USGS's underlying values for Marysville: 0.225g peak ground acceleration, 0.522g at short period, 0.249g at 1 second. Within California alone, Marysville ranks 412 of 429 cities by seismic hazard - the 4th percentile in-state. Marysville has a population of about 12,714.

Bracing and bolting: the actual cost

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.

What this means for insurance

Marysville 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 Marysville's figures come from

Marysville's Category C 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.
