What Is a Flood Insurance Rate Map?
Before private flood insurance became a readily available option, most homeowners in need of flood insurance turned to the Federal Emergency Management Agency (FEMA) for protection. FEMA established the NFIP to provide low-cost insurance to high-risk homes.
Since every community and region has a different risk of flooding, FEMA established FIRMs to determine any given area’s flood risk and estimated insurance rates. You can access these flood maps through FEMA ’s map service center. After inputting your address or community, you can view the FIRM for your chosen municipality.
At first glance, FIRMs can seem overwhelming and confusing. Don’t freak out—reading a FIRM is simple once you understand the information it’s showing you.
There are a few terms you’ll need to know in determining your home’s flood risk. First and most important, a Special Flood Hazard Area ( SFHA ) is any area that has a one percent chance or higher of flooding in any given year. SFHAs are also commonly referred to as 100-year floodplains. FEMA Flood Insurance Rate Maps typically indicate SFHAs with blue shading.
Within SFHAs, there are flood zone designations, which indicate low-risk, moderate-risk, and high-risk flood areas. High-risk flood zones begin with letters A and V, while lower- risk areas are marked B, C, and X. Keep in mind that low-risk doesn’t mean there is no risk, as nearly every home has some annual chance of flooding.
FIRMs also illustrate the base flood elevation ( BFE ) of the city you live in. Your BFE is the level floodwaters are expected to rise during a 100-year flood. This is especially important to homeowners who live in risk areas. If your home’s lowest floor falls below your BFE, it means your home has a high risk of sustaining flood damage. Most homeowners who live in risk zones are required to provide their home’s elevation certificate before obtaining a flood insurance policy for this reason.
