Parkville's Seismic Design Category, explained

Parkville carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Rank it against the rest of the country and Parkville sits at the 24th percentile for seismic hazard among 4,875 US cities.

Parkville by the numbers

USGS's underlying values for Parkville: 0.044g peak ground acceleration, 0.093g at short period, 0.068g at 1 second. Within Missouri alone, Parkville ranks 128 of 135 cities by seismic hazard - the 5th percentile in-state. Parkville has a population of about 8,980.

Retrofit economics for Parkville

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 Missouri 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 Missouri.

Insuring against this, not just retrofitting

A Parkville 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 Parkville's figures come from

Parkville's Category B 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 B does and doesn't tell you about Parkville.
