With few exceptions, if you live in Louisiana, you should have flood insurance. Flood damage is not covered under your homeowner's insurance policy. A flood without insurance is a terrible financial setback. And if your home is in an identified Special Flood Hazard Area (commonly called "the flood zone") and you do not have flood insurance, some forms of disaster recovery assistance may be denied or reduced.Awardees in The Road Home program are required to carry flood insurance of their property if it is in the flood zone, as shown on FEMA post-Katrina/Rita advisory maps, for a period of three years (five years, in some cases).
Are you wondering "what counts" when calculating your premium? Here are some general rating guidelines and rate comparisons:
What risk zone is the building in (on the Flood Insurance Rate Map or FIRM)?
Three types of risk zones on the FIRM are used in determining the insurance premium:
Areas of minimal flood risk. These are the X zones on recent maps and C zones on older maps. The X zones include areas with 0.2% annual risk, formerly known and mapped as B zones. The B zones have been rolled into the X-zone category. Properties in B, C or X zones may qualify for a Preferred Risk flood insurance policy.
Areas at risk from water with little or no waves (not exceeding 3-foot crest height). These are the A zones on both new and old maps.
Areas at risk from water that has waves 3 feet or higher. The wave action imposes a different force on a structure than water without wave action. These are the V zones, typically found along coastlines and lakeshores.
How many times has the building flooded?
Strange as it may seem, the flood history of a structure has no bearing on the flood insurance premiums in special flood hazard areas (A and V zones). At worst, a history of flooding will disqualify a property in a minimal risk zone (B, C or X) from obtaining a preferred-risk policy, but it will not otherwise affect the premium for a standard flood insurance policy in those zones.
How old is the building, and how high?
The absolute age of the building is not significant. What matters is whether the building is older than the flood map. Buildings that were built before the community got its first FIRM can be insured at a federally subsidized PreFIRM rate. For PreFIRM-rated buildings, the height of the floor above or below BFE is not a factor. The PreFIRM rate is about 30% more than the PostFIRM building built at BFE, all other things being equal. For example, for $100,000 of building coverage on a single-story home with no basement in an A zone: if the PreFIRM rate were $625, the PostFIRM rate for a building at BFE (plus or minus 6 inches) would be $521. Owners of PreFIRM buildings can elect to be insured at the PostFIRM rate if they obtain an elevation certificate showing the structure is at, above or less than 6 inches below the 100-year flood level shown on the map. You do not lose a PreFIRM rate if the elevation certificate shows the building is well below BFE.
Buildings that were built after the community got its first FIRM must be insured at the PostFIRM rate, with some exceptions given for changes in the maps. For PostFIRM rating, the elevation in relation to BFE is important, as is the risk zone (A or V). Compare the premiums for $100,000 of building coverage on a single-family home:
Post-FIRM Elevated Floor, at BFE
V zones, after 1981
Pre-FIRM One Floor, no Basement
Post-FIRMOne Floor, no Basement
Pre/Post-FIRMOne Floor, no Basement

Is the building used for residential or non-residential purposes?
