What does each zone on the St. Johns County map mean?
- A zones High risk. Land with at least a 1% chance of flooding in any year. Zone AE shows the base flood elevation, the height the water is expected to reach.
- V zones High risk, with waves. Coastal land where waves push in, not just rising water. Zone VE has the strictest building rules.
- Zone X Outside the high-risk area. Land outside the A and V zones is Zone X. A lender does not have to require flood insurance there. FEMA still rates Zone X as moderate or minimal risk, not no risk.
The letter decides the requirement. It does not decide your price. The building does.

Same flood zone, very different prices in St. Johns County. Here is why.
Your flood zone decides if your lender requires a policy. Under Risk Rating 2.0, the price depends on the home: how often it could flood, how close it sits to the water, its first floor height and what it would cost to rebuild.
An elevation certificate shows your first floor height against the base flood elevation. See St. Johns County's elevation certificate page.

What flood zones in Florida require flood insurance?
Zones that start with A or V are the high-risk area. If your home is there and your loan is federally backed, your lender has to require flood insurance. Zone X is outside that area, so the lender does not have to require it. FEMA still rates Zone X as moderate or minimal risk, not no risk.
What's the worst flood zone to be in?
V zones, and Zone VE most of all. VE means waves, not just rising water, and the strictest building rules. Still, the zone decides the requirement, not the price. The price depends on the home, so two St. Johns County homes in the same zone can pay very different amounts.
