Edgewater's Seismic Design Category, explained
USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Edgewater in Seismic Design Category A: Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. That puts Edgewater in the 11th percentile nationally for seismic hazard - higher than 11% of the 4,875 US cities USGS was checked against here.
Where Edgewater sits in Florida
USGS's underlying values for Edgewater: 0.031g peak ground acceleration, 0.066g at short period, 0.036g at 1 second. Within Florida alone, Edgewater ranks 53 of 228 cities by seismic hazard - the 77th percentile in-state. Edgewater has a population of about 24,334.
Bracing and bolting: the actual cost
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 Florida 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 Florida.
What this means for insurance
A Edgewater 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 Edgewater's figures come from
Edgewater's Category A 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 A does and doesn't tell you about Edgewater.
