A flooding complaint is not one claim. It is a family of claims that share a photograph. Before the association concedes anything or spends anything, the board needs to know which of three stories the water is telling: the system was built wrong, the system was not maintained, or the rain exceeded what the system was ever meant to hold. The answer determines who is liable, who insures it, who pays for it, and how long anyone has to sue.

The first two weeks decide the case

Whatever else the board does, it should treat a flooding complaint as an evidence problem before it treats it as a legal one. Most of what will decide the dispute is measurable for about ten days and then gone.

1. Photograph and, better, survey the high water marks while they are visible. Mud lines on stucco, silt lines on sod and debris lines on fences are datable evidence of elevation.
2. Record the finished floor elevation of the affected home and the elevations of the nearest inlet, swale invert and lake control structure. An elevation certificate, if one exists, is the cheapest document in the file.
3. Photograph every inlet, grate, pipe end, control structure, weir and outfall in the affected basin, including the ones that worked.
4. Pull the rainfall record for the specific event from the water management district or the National Weather Service, with the duration, not only the total.
5. Collect the association's maintenance records for the basin: inspection reports, vendor invoices, pipe cleaning, mowing, aquatic treatment, and any prior complaint about the same area.
6. Issue a litigation hold. Stop the routine deletion of emails, text messages and vendor reports, and tell the manager in writing.

Two cautions. Do not have a board member write an opinion about causation in an email; that email will be read aloud later. And do not direct repairs that change the condition of the system before it has been documented, unless the repair is genuinely urgent, in which case document the urgency first. Our note on litigation holds and record preservation covers the mechanics.

The legal standard: reasonable use

Florida does not apply the common enemy rule, under which a landowner may do as he likes with surface water, and it does not apply the strict civil law rule, under which the lower owner must accept whatever comes. In Westland Skating Center, Inc. v. Gus Machado Buick, Inc., 542 So. 2d 959 (Fla. 1989), the Florida Supreme Court adopted the reasonable use rule: each possessor is legally privileged to make reasonable use of his land even though the flow of surface waters is altered and causes some harm to others, and incurs liability only when his harmful interference with the flow of surface waters is unreasonable.

The court drew the test from the Restatement (Second) of Torts section 833, which resolves surface water interference under nuisance principles. If the interference is intentional, the conduct is measured for reasonableness. If unintentional, the test is negligence. Reasonableness is assessed in view of all the circumstances, and compliance with a building code or a permit is evidence of reasonableness rather than reasonableness as a matter of law.

Two consequences follow for a board. First, the rule cuts both ways: an owner who berms his own lot, fills a swale or blocks a rear-lot conveyance is judged by the same standard he is applying to the association. That is frequently the real story in a single-home flooding complaint. Second, the existence of an environmental resource permit does not decide the case. The permitting program under Part IV of Chapter 373 is layered onto the common law of drainage rights and has not displaced it, and the water management districts have no jurisdiction to resolve property disputes between neighbors through the permit process.

Three cases that look the same on day one

Sorting the three is the engineer's job, not the board's, and it should be done before the association takes a position in writing. A board that announces "this was an act of God" in the January newsletter and then discovers the outfall pipe was eighty percent silted has made its own case considerably harder.

The design standard nobody explained to the owner

A stormwater system is not designed so that nothing ever floods. It is designed to a storm. Under the South Florida Water Management District's environmental resource permit criteria, offsite discharge rates are computed using a 25-year, 3-day storm event unless a prior permit or the basin criteria specify otherwise, and building floor elevations are set considering both tidal flooding and the 100-year, 3-day storm event.

Those two numbers do a great deal of work in a flooding dispute. A system that performed exactly as designed can still put water in a garage in a storm larger than the design event, and that is not a defect. It is the design. Owners are rarely told this when they buy, and the first time most of them hear it is from an angry board member at a meeting, which is the worst possible setting for the conversation.

The board should know two things about its own community before a storm: which design event its permit was issued under, and whether the finished floor elevations in the affected area actually meet the permitted standard. Both are answerable from the permit file and the as-built certification. In communities that have been through Hurricane Ian and the 2024 storms, this is worth doing as a matter of routine rather than in response to a demand letter. Our hurricane preparation resources cover the operational side.

The association's maintenance duty

The duty has two independent sources, and a plaintiff will plead both.

The first is the declaration, which in most Southwest Florida communities makes the association responsible for the surface water management system, the lakes and the conveyances. Section 720.303(1), Florida Statutes, provides that the powers and duties of an association include those set out in Chapter 720 and, except as the chapter limits them, those set out in the governing documents, and that officers and directors have a fiduciary relationship to the members.

The second is the permit. The system is regulated under Part IV of Chapter 373, Florida Statutes, and Chapter 62-330, Florida Administrative Code. Rule 62-330.310(6), F.A.C. keeps the operation and maintenance entity liable for compliance in perpetuity unless the permit is transferred. General condition (a) in rule 62-330.350(1), F.A.C. requires that activities be implemented following the approved plans and specifications, and general condition (p) requires routine maintenance of all components of the stormwater management system, including removal of trapped sediments and debris. Our guide to HOA stormwater responsibilities sets out that obligation in full.

The practical test a plaintiff's lawyer will apply is simple and boards should apply it first: can the association produce a record showing that it inspected the system on a schedule, found what it found, and acted on it? Vendor invoices for spraying a lake are not that record. An association with an annual inspection report and a repair log is in a materially different position from one with a folder of invoices, even where the water behaved identically.

Insurance, and the exclusion that catches boards out

Three coverage questions arise, and they usually have three different answers.

• The owner's own loss. Standard homeowners policies exclude flood and surface water damage. Coverage for that loss, if it exists, comes from a separate flood policy, whether through the National Flood Insurance Program or the private market. Many Southwest Florida owners outside a mapped high-risk zone carry none.
• The association's liability. A commercial general liability policy responds to property damage the association is legally obligated to pay, but property and liability forms commonly carry water and surface water exclusions, and coverage often turns on whether the damage is characterized as resulting from the association's negligent maintenance rather than from flood as such.
• The board's own exposure. A directors and officers policy responds to claims for wrongful acts in the management of the association, and typically excludes bodily injury and property damage, which is the heart of a flooding claim. Boards that assume the D&O policy covers this are usually wrong.

Report the claim to every carrier that might conceivably respond, and do it early. Late notice is a defense carriers use, and the cost of an unnecessary notice is nothing. Our guidance on documenting an insurance claim applies here with one addition: the documentation that matters in a flooding claim is elevation data, not photographs of wet carpet.

Presuit mediation under section 720.311

Section 720.311(2)(a), Florida Statutes, requires presuit mediation for certain homeowners association disputes before an action may be filed: disputes over the use of or changes to a parcel or the common areas, other covenant enforcement disputes, disputes over amendments to the association documents, disputes over board and committee meetings and over membership meetings other than election meetings, and disputes over access to the official records. Collection of assessments, fines and other financial obligations is excluded, as are claims for attorney's fees and costs, enforcement of a prior mediation settlement, and election and recall disputes, which go to arbitration.

The mechanics matter. The aggrieved party serves a statutory demand form by certified mail listing five circuit-court-certified mediators and their hourly rates. Under section 720.311(2)(b), the responding party has 20 days from the date of mailing to serve a written response. The parties share the mediator's fees equally unless they agree otherwise. The provision boards should focus on is the penalty: a person who fails or refuses to participate in the entire mediation process may not recover attorney's fees and costs in subsequent litigation relating to the dispute.

Whether a flooding claim falls inside that list is genuinely unsettled. A claim framed as the association's failure to maintain the common areas looks like a dispute over the common areas. The same facts pleaded as ordinary negligence for property damage look like a tort claim that the statute does not reach. Owners' counsel and association counsel routinely take opposite positions on this, and the answer can change the timing of the whole dispute. The safe course for an association that receives a demand is to respond within 20 days and participate, because the downside of guessing wrong is losing the ability to recover fees.

Deadlines and experts

Limitations periods in this area are shorter than most boards expect. An action founded on negligence must be brought within two years under section 95.11(5)(a), Florida Statutes. An action for trespass on real property has four years under section 95.11(3)(f). A claim founded on the design, planning or construction of an improvement to real property runs four years from the time the defect is discovered or should have been discovered with due diligence, subject to a seven-year repose measured from the earliest of a temporary certificate of occupancy, a certificate of occupancy, a certificate of completion, or abandonment of construction.

That repose period is why a developer-era design problem in a community built in the 2000s is usually no longer actionable against anyone, and why the association ends up carrying a deficiency it did not create. Where the community is newer and the numbers still work, the analysis runs through the construction defect framework rather than the surface water one. Our guide to construction defect claims covers the presuit notice process.

On experts: retain the engineer through counsel, not directly, and retain one early. A drainage dispute is decided by hydraulics, and the board's instinct to get a second opinion from the landscape vendor is the most common unforced error in these matters. Where the association's own engineer designed or approved the work in question, use a different engineer for the opinion.
