Storm, elevation and surge

How exposed is this address, actually?

Not a forecast and not a scare. The flood map, the elevation the map expects, and the deductible you would actually pay if a named storm took the roof off. Ian taught everybody here that the difference between two streets can be the whole house.

Put the city and state on the end if the first try does not match.
Not the price you would pay for it. The cost to build it again, which is what the policy insures and what the deductible is a percentage of.

Type an address and I will read it off the FEMA National Flood Hazard Layer, the same map a lender and an insurer use.

If a named storm damages the house

Florida hurricane deductibles are a percentage of the insured value of the building, not a flat sum and not a percentage of the claim. On a rebuild cost, that is the amount you pay before the policy pays anything. It applies once per hurricane season, not per storm.

What the letters mean

A flood zone is not a prediction. It is a betting line.

FEMA is estimating the chance of water reaching a level in any given year. It says nothing about whether this particular house has ever flooded, which is a separate question worth asking the seller in writing.

Zones beginning with V

Coastal high hazard. FEMA expects waves on top of the surge. This is the most expensive ground to insure in the county and the hardest to rebuild on, because the construction standards are stricter.

Zones beginning with A

High risk, roughly a one in a hundred chance in any year. A lender will require flood cover. Where the map gives a base flood elevation, an elevation certificate showing your floor above it can move the premium a long way.

X, and shaded X

Outside the high risk area, which is not the same as safe. A great many homes that took water in Ian were in X. Cover is cheap here and worth having.

Base flood elevation

The height FEMA expects water to reach. What matters is where your finished floor sits against it. Above, and both the risk and the premium fall. Below, and you are paying for the difference every year until somebody lifts the house.

Evacuation zones are a different map, drawn by the county rather than FEMA, and they do not line up with flood zones. Look yours up with Lee County or Collier County before hurricane season rather than during it.

Know this before you are under contract.

Insurance and flood end more contracts here than price does, and they end them in week six when everybody is already invested. Ten minutes now is worth a great deal later.
