What does each zone on the St. Lucie County map mean?

The letter decides the requirement. It does not decide your price. The building does.

V zones
High risk, with waves

Coastal land where waves push in, not just rising water. Zone VE has the strictest building rules.

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.

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.

What sets the price

Same flood zone, very different prices in St. Lucie 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.

Unincorporated St. Lucie County: Community Rating System Class 5, 25% discount, on a scale that tops out at 45%. 0% 45%
Unincorporated St. Lucie County earns 25% off eligible NFIP flood premiums.

Checked against FEMA’s flood map for that exact spot.

No thanks, I hate discounts.

Quick answers

Questions about the St. Lucie County flood zone map?

How can I find my flood zone in St. Lucie County?

Type your address in the ShoutFlood address check at the top of the page. It reads FEMA's flood map for that spot and shows your zone. You can also search St. Lucie County's Flood Information Map or FEMA's Flood Map Service Center.

How can I check if my address is in a flood zone in Florida?

Enter your address in the ShoutFlood check, or search FEMA's Flood Map Service Center, which covers every Florida address.

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. Lucie County homes in the same zone can pay very different amounts.
