Flood insurance, because the other policy does not do this
Rising water is excluded from every homeowners policy in the country. In a county built on drained wetland at sea level, that exclusion is the most important sentence in your file.
Sa sa touche
- The building: structure, foundation, systems, built-in appliances
- Contents, which is a separate limit and a separate decision
- Debris removal after the water goes down
- Private flood options, which often go higher than the NFIP limits and sometimes cost less
The waiting period, and the deadline that follows from it
An NFIP policy normally takes effect 30 days after you buy it. That means flood insurance cannot be bought when a storm is named, and every June somebody learns that the hard way. There are narrow exceptions, including a purchase tied to a mortgage closing. Buy it in the quiet months.
What moves the premium
- Your flood zone, and just as much, your elevation certificate if the building has one.
- Whether the lowest floor is elevated, and by how much, relative to base flood elevation.
- The building's foundation type and whether there is an enclosure below.
- Coverage limits and deductible, and whether NFIP or a private carrier is the better answer for your specific structure.
Outside a flood zone is not outside flood risk
About 9% of the NFIP flood claims on record in Miami-Dade, and 11% in Broward, were on policies rated in a low risk zone. Zone X is where the cheapest flood policies live, and in this market buying one there is frequently the best value decision on the whole account.
Citizens and flood
Citizens has been phasing in a requirement that its personal residential policyholders carry flood coverage. If you are with Citizens, this is not optional advice, it is a condition of the policy, and the phase-in date depends on your coverage amount. Ask us where your policy sits.

How deep the water was in Miami-Dade
Where interior depth was recorded, most of it was shallow. A few inches across a floor is a claim, not an inconvenience.
Interior depth was recorded on 2,717 of the 62,027 claim records for this county, so this chart describes those, not all of them.

Kesyon moun poze vre
I am not in a flood zone. Do I need it?
Everywhere is in a flood zone. Some of them are low risk, and low risk policies are inexpensive. That is a reason to buy, not a reason to skip.
Does the NFIP cover my contents?
Only if you buy contents coverage, and basements and enclosures are treated very restrictively. We will walk through what is and is not included.
