what flood zones require insurance?

Flood zones reflect the probability of a flood occurring in a particular area. Even in the most flood-prone communities, the chance of flooding in any given year is low, typically between 0.2% and 1.0%.

A 1% annual risk of flooding translates to a 26% chance of experiencing a flood at least once during the life of a 30-year mortgage.

The National Flood Insurance Program (NFIP), a division of FEMA, will sell a policy to any homeowner who lives in a flood zone, regardless of risk.

You can also purchase a flood policy from a private insurer, but private insurers may not offer coverage to homeowners in higher-risk areas.

How do I know if I need flood insurance?

You can use the FEMA (Firm) Flood Insurance Rate Map to find your property’s flood zone. Please be patient with this map and website as it may take a while to load. once you can see your address on the map, you will be able to find your nearby flood zone.

If a property covers two or more flood zones, your insurer will base your flood insurance rate on the most dangerous zone.

How are flood insurance rates calculated?

fema and the nfip recently implemented a new method for calculating flood insurance premiums called risk rating 2.0. the new method uses property-specific data to calculate your flood insurance rate, rather than determining risk based on where your property is located on a flood map. this means your rate will better reflect the flood risk of your individual property.

In addition, these factors are ranked based on the likelihood of your property experiencing events such as inland flooding, storm surge, tsunami, and coastal erosion.

These metrics are combined to determine a base rate to protect the structure of your home and the cost to replace its contents. the base rate is for $1,000 of coverage, which can then be multiplied by the amount of protection you need.

for example, a house in south carolina is located 120 yards from a river and four miles from the ocean. the property is 4.6 feet above the river level and the first floor is 5.5 feet from the ground. Based on these factors and more, an NFIP policy would cost $2.67 per $1,000 of coverage for the building and $3.80 per $1,000 of coverage for your home contents.

for comparison, a house in california located 40 yards from the river and 1.5 miles from the sea. the property sits one foot above the level of the river, and the first floor is raised half a foot above the ground. A policy for this home would cost $4.42 per $1,000 of building coverage and $6.87 per $1,000 of home contents coverage.

what does your home’s flood factor mean?

Your flood factor is determined based on the probability that your property will be flooded over a 30-year period and the probability that one inch of water will reach your home. Homes are ranked from one to 10, with a higher score meaning you are more likely to experience a flood and the flood will be deeper than average.
