Is my Vero Beach home in a flood zone? How to look it up, and why city or county matters

Ask a neighbor what flood zone they live in, and many will shrug. That is normal. Most of us learn our flood zone once, at closing, and then forget it.

It is worth knowing. Your flood zone shapes the rules for a big remodel, whether a lender requires flood insurance, and how much risk your house carries when the lagoon or a heavy rain pushes water up into the street. The good news: you can look it up yourself, for free, in a few minutes.

First question: are you in the city or the county?

Plenty of homes with a Vero Beach mailing address are not inside the City of Vero Beach. They sit in unincorporated Indian River County. That matters, because each government runs its own floodplain office, keeps its own elevation certificates and has its own flood rules.

The city's Flood Resources and Maps page has an "Am I a City or County Resident?" lookup tool. Use it first. It takes a few seconds.

• Inside the city: flood rules are in Chapter 73 of the city code (Flood Damage Prevention and Drainage). Help comes from the Planning and Development Department at City Hall, 1053 20th Place, 772-978-4550.
• In the unincorporated county: flood rules are in Chapter 930 of the county's land development regulations. Help comes from the county Planning Division at 772-226-1237. The county also lists a floodplain coordinator, Kari Cundiff, at 772-226-1590.

How to look up your flood zone

FEMA's Flood Map Service Center is the official source for flood maps. Type your address into the Address Search box. The site finds the current Flood Insurance Rate Map, or FIRM, for your spot. You can click View and use the FIRMette tool to make a printable one-page map of your area.

There are local shortcuts too. The city links to its own GIS map of flood zones. The county has partnered with a company called Forerunner on a flood website that shows the flood risk for a specific property and, where the county has them, elevation certificates and related documents.

According to the county, the current flood maps took effect on Jan. 26, 2023, and permits are now reviewed against them. If you looked up your zone before then, look again.

What the letters mean

• Zones that start with A (like AE) are high-risk areas. AE zones show a Base Flood Elevation, the height water is expected to reach in a major flood.
• Zones that start with V (like VE) are high-risk coastal areas with the added danger of storm waves.
• Zone X is moderate or lower risk. Lower risk is not no risk. FEMA says these areas are "not entirely without risk" and recommends flood insurance there too.
• In high-risk A and V zones, a federally backed mortgage requires flood insurance in communities that take part in the National Flood Insurance Program. Vero Beach has taken part since 1977.

Vero's own numbers show why this matters. A 2023 city study of repeat-flooding areas found most of the homes it looked at west of Indian River Boulevard were in Zone AE with a Base Flood Elevation of 4 feet. In one of those areas, most homes were built from 1965 to 1974. In the homeowner survey for that study, 47% of those who had flooded blamed water rising over the banks, and 21% blamed storm sewers backing up.

What to do this week

1. Find out if you are in the city or the county using the city's "Am I a City or County Resident?" tool.
2. Look up your address on msc.fema.gov. Write down your zone and, if you are in an A or V zone, your Base Flood Elevation. Save a FIRMette to your files.
3. Ask for your elevation certificate. The city says completed certificates for many existing homes may be on file with Planning and Development. The county says its Building Division or Environmental Planning section has them for previously developed properties back to 1997.
4. Planning a big remodel or addition? Ask the floodplain office about the 50% rule first. In the city, if the work equals or tops 50% of the building's market value, the whole house must meet new-building flood standards.
5. Keep water moving. Clear leaves out of your swale and report a clogged storm drain. Inside the city, call Public Works at 772-978-4870.
6. Move valuables up. The city suggests raising or moving electric panels, water heaters and washers and dryers if they are at risk, and keeping furniture and valuables above flood level.

One more tip: flood maps change. FEMA suggests checking your zone every year, and it only takes a minute once you know where to look.
