Vero Beach Seawall Height and Survey Guidance
The sources reviewed do not establish one minimum seawall cap elevation for every Vero Beach property. Start with your survey reference, waterfront location and proposed work.
- Top of the capMeasured from a fixed survey reference.
- WaterlineRises and falls with tides and weather.
- Survey reference (datum)A named reference, such as NAVD88.
Use the survey reference printed beside the elevation.
How high should your seawall be?
Your city or county may set a lowest or highest allowed elevation for the top of the wall. The rules can change with the property’s location and the work planned. Drainage, flooding and neighboring properties also affect the design.
For local height rules, use the top-of-cap elevation on your survey. This is the top of the wall measured from a fixed survey reference. It is different from the wall’s bottom-to-top height or the water level.
Find these two items on your survey.
Find the elevation for the top of the seawall cap and the survey reference used with it. The example below shows what to look for.
Seawall cap elevation
- Top of seawall cap
- 6.00 ft
- Survey reference (datum)
- NAVD88
This example shows 6.00 ft NAVD88. Use the number and reference on your own survey.
Match the value and the reference.
- The elevation: use the number for the top of the wall cap, not a building floor, water depth or the wall’s full height.
- The reference: copy the name beside the elevation, such as NAVD88 or NGVD29. You can compare elevations only when they use the same reference.
- Cannot find both? Choose “No / not sure” in the checker. Ask a surveyor to help find them; measuring from the water will give a different result.
What does NAVD88 mean?
NAVD88 is a fixed survey reference used to measure elevations, like a shared zero point. Another survey may use NGVD29 or a tide-based reference. To compare two elevations, they must use the same reference. A surveyor can help if the references differ. Read NOAA’s explanation of survey references.
Look for the seawall cap elevation on your survey or final construction plans. A flood certificate may show only the building’s elevation. If the wall measurement is missing, ask a surveyor; you do not need to measure beside the water.
Repair, replacement and permits
Before raising or replacing the wall, ask the permitting office which rules apply to the work. An engineer can check whether the existing wall, supports and drainage can handle the change. A higher wall can also change where rainwater flows.
Use the permit guide to find the local, Florida DEP and U.S. Army Corps of Engineers contacts. Describe your location and planned work and ask which permits you need. Florida DEP’s application instructions explain the information needed for shoreline projects.
Common questions
How do I plan a change in wall height?
Start with your survey, the wall’s condition and the change you want to make. An engineer can check the supports, drainage and effects on nearby properties. Tell us about your plans and we’ll help you prepare the next step.
Is maximum height the height I must build?
A maximum is the highest allowed elevation, not a target you must build to. Ask your permitting office whether there is also a minimum for your property.
What if I do not know the elevation?
You can start with the property address and what you want to change. A surveyor can identify the top-of-cap elevation and its reference on your survey.
Can an existing seawall be raised?
An engineer needs to check the wall, supports and drainage before recommending a height change. The right approach may involve modifying the wall or replacing parts of it.
Does meeting a number mean the wall is safe?
Height is only one part of the wall’s condition. The supports, drainage and signs of damage also matter. Use the warning-sign check to prepare for an assessment.
How can I get help with the height?
Tell us the property’s city or county and what you want to change. Discuss the next steps, including whether you need a survey or seawall assessment. Confirm any service details and price before going ahead.
Confirm the property and proposed change first.
There is no universal Vero Beach minimum cap elevation established by the sources reviewed for this guide. Give the permitting office the parcel, current survey and proposed repair or replacement instead of relying on a number quoted for another city.
Within Vero Beach, applicable city planning or code-compliance approvals precede county building review. Indian River Shores and Orchid operate separate building departments. Oceanfront beach-dune work can involve CCCL requirements as well, so identify which side of the shoreline the project occupies.

Do not compare elevations until the references match.
Find the top-of-cap value and datum together. NAVD88, NGVD29 and local tidal datums are different references; none can be substituted merely because the number is expressed in feet. NOAA publishes relationships where the necessary benchmark connections exist.
Ask the surveyor to explain any conversion needed between older plans and a current survey. A flood-map building elevation is a separate item, not an automatic seawall cap requirement. The county’s January 26, 2023 flood-map update is a reason to check the current panel, not to infer a wall height.

Bring water movement and runoff into the design.
SJRWMD explains that wind moves lagoon water more than tides do. One calm-day waterline or an ocean tide chart therefore cannot set a parcel’s design elevation.
A cap increase also needs a drainage discussion. Vero Beach’s code-compliance instructions identify changed drainage as a possible reason for plans or calculations. Ask the engineer about the existing wall’s capacity, adjoining conditions and the intended route for runoff before treating extra cap height as a stand-alone repair.
