Lake bank damage after a hurricane: what to do first
After a hurricane, an HOA board should first keep people away from damaged banks, then photograph every section with dates, and then get the banks measured so it has a written record before anyone starts repairs. The sections closest to homes and the broken drain pipes come first, and the worst sections should be fixed before the next wet season makes them bigger.
Why hurricanes do so much damage to lake banks
A hurricane does in 1 night what a normal wet season does in years. The lake rises fast, runoff pours down every slope, and wind drives waves into the bank. When the water drops, sections that were already weak can be undercut, slumped or gone. One Florida district is still restoring residential lake banks damaged by Hurricanes Irma in 2017 and Ian in 2022.
That last point matters for boards. Storm damage to lake banks is not always fixed in the months after the storm. Some communities spend years catching up, and the banks that were left alone keep getting worse with each wet season. For background on the slow damage that sets banks up to fail in a storm, see why lake banks erode.
What storm damage looks like
Boards and managers should know the common signs, because some of them are easy to miss from the top of the bank.
- Undercutting. The water has carved out soil under the grass line, leaving a lip of turf with little or nothing under it.
- Slumping. A section of bank has slid down toward the water, often leaving a crack or step in the lawn above it.
- Collapse. The bank has fallen into the lake, and the edge of the water is now closer to fences, patios or pool decks.
- Exposed or broken pipes. Drain pipes and outfalls that used to be buried are now in the open, cracked or pulled apart.
- New gullies. Runoff has cut channels down the slope, often where roof drains or swales empty toward the lake.
What to do in the first week
- Keep people back from the edge. An undercut bank can look solid from the top and give way under a person's weight. Tell residents in writing to stay off damaged sections.
- Photograph everything, with dates. Walk every lake and photograph each damaged section from the same spots each time. These photos are the record your insurer, your manager and any contractor will need.
- Mark the sections closest to homes. Banks within a few feet of fences, patios, pool decks and foundations come first.
- Check the pipes and outfalls. Storms expose and break drain pipes along the bank. A broken pipe keeps washing soil out after the storm is gone.
How to take photos that hold up later
Good photos save arguments months later. Stand at a fixed point for each section, such as a lot line, a light pole or a numbered stake, and take the same shot each time you return. Include something for scale, such as a fence post or a measuring tape. Note the date, the lake and the section number in a simple log. If you can, take a wide shot that shows the home behind the bank and a close shot that shows the edge itself.
Do this again a few weeks later. A bank that is still moving after the storm will show it, and that tells the board which sections cannot wait.
What to tell residents
Send a short written notice to every owner on a lake. Tell them which sections are damaged, ask them to keep children and pets away from the edge, and ask them not to mow, walk or put equipment on those sections. Ask them to report any new cracks, sinking or exposed pipe to the manager. Keep a copy of the notice for the association's records.
What to do in the first month
- Call your insurance agent. Many property policies exclude earth movement. Ask in writing whether lake bank damage, or damage it causes to resident property, is covered.
- Get the banks measured. A written report with measurements and photos of every section gives the board a clear record of what the storm did and what needs to be fixed.
- Fix the worst sections before the next wet season. A damaged bank that sits through another wet season gets bigger, and so does the repair.
Insurance and responsibility questions
Boards often want to know who pays and who is responsible for a damaged bank behind a home. Those are questions for the association's attorney and insurance agent, not for a contractor. What the board can do is give them a clean record: dated photos, measurements, and a list of which sections sit near resident property. Our guide on who is responsible for lake bank erosion explains what boards usually look at, and which documents to pull before that conversation.
Ask your agent for answers in writing, and keep them with the minutes. If the board makes a decision based on what it was told, the written answer protects the board.
How to decide what gets fixed first
Most communities cannot fix every damaged foot of bank at once. A simple way to rank sections is to look at what sits behind them and how fast they are moving.
| Priority | What it looks like | What to do |
|---|---|---|
| First | Bank within a few feet of a fence, patio, pool deck or foundation, or still moving after the storm | Rebuild before the next wet season |
| Second | Broken or exposed drain pipes and outfalls | Repair the pipe and the bank around it together |
| Third | Undercut or slumped bank with open lawn behind it | Plan and budget for the next phase |
| Watch | Minor scarps or bare spots that have not moved | Photograph again after each heavy rain |
This order is a starting point. A section with a small amount of damage can still move up the list if a resident's structure is close, or if the photos show it moving week after week.
How damage grows over several wet seasons
A bank that was undercut in a storm rarely stays the same. In the first wet season after the storm, rising water reaches the bare soil under the lip and carries more of it away. The lip collapses, and the edge moves back. In the second season, the new edge is steeper and closer to homes, so it erodes faster. By the third season, a repair that could have been done on a short section of bank may now involve a fence line, a patio and a drain pipe.
That is why the board should not wait for the next storm to act. The wet season runs May through October in South Florida, and the months before it are the best time to repair the sections that matter most. Our guide to budgeting and phasing a lake bank repair shows how to split the work over more than 1 year.
Common mistakes after a storm
The first mistake is regrading and laying sod over storm damage and calling it done. That approach usually fails at the waterline within a season or 2, because nothing holds the soil under the grass. Our guide on why regrade and sod fails explains the pattern.
The second is fixing only the sections residents complain about. The loudest complaint is not always the worst bank. A measured walk of every lake gives the board a fair way to rank the work.
The third is losing the record. Photos on a manager's phone or scattered across emails are hard to use later. Keep them in 1 folder, by lake and section, with dates.
The fourth is hiring the first contractor available without a written scope. After a storm, many companies offer to help. A clear scope lets every bidder price the same work.
How we help after a storm
We walk the banks, measure and photograph every section, and give the board a written report that separates what needs work now from what can wait. We rebuild the slope from the waterline up with leading edge technology that lets the grass root into the bank so it holds, and we keep the work at the bank and out of residents' yards. We do not publish how we do it.
Every job carries a 5 year material and 5 year labor warranty in writing, with inspections in years 3, 5, 7 and 9, each with a written report for the minutes. We do every foot of the work ourselves with no subcontracted crews.
Before the walk, the Lake Bank Risk Score gives the board a quick first read on how serious the damage is. To get every section measured and photographed, book a free lake bank walk or call (561) 309 9603.
Questions boards ask
How soon after a hurricane should we look at the lake banks?
As soon as it is safe to walk the property. Photograph every section in the first week, then again a few weeks later to see which sections are still moving. The first photos are the record of what the storm did.
Is lake bank damage covered by our insurance?
Ask your insurance agent in writing. Many property policies exclude earth movement, and coverage for damage to resident property is a separate question. The association's agent and attorney are the right people to answer it.
Can we wait until after the next wet season to repair?
The sections near homes, structures and broken pipes usually cannot wait. A damaged bank that sits through another wet season gets bigger, and so does the repair. Sections with open lawn behind them can often be phased into a later year.
What should our written damage report include?
It should list every section by lake and number, with its length, how far it has cut back, what sits near it, and dated photos. It should separate what needs work now from what can wait. A report like that also becomes the basis for a scope every bidder can price the same way.
Can we test the repair before committing to every lake?
Yes. Many boards approve a short section first where residents can see it. Our Proof Section is about 100 feet at a spot residents can see, and the fee is credited to the full job.
