These areas are subject to a one percent chance of flooding annually and are mandatory flood insurance areas. These zones have a BFE that’s used to determine the rate as shown in FEMA’s Flood Insurance Rate Map (FIRM). Flood Zone AE, A1-A30įlood Zone AE is a newer version of what used to be Flood Zones A1-A30. There are no detailed analyses of areas in Flood Zone A, so there are no depths or base flood elevations (BFE) in this zone. Over the course of a 30-year mortgage, the likelihood of a flood is 26 percent. Flood Zone Aįlood Zone A is a high-risk flood zone that has a one percent chance of flooding each year. Flood insurance is required in Zone A because the area has a high chance of experiencing a 100-Year Flood – a flood that has a one percent annual chance of happening. Zone A denotes inland areas that are at high risk for flooding and encompasses A, AO, A1-A30, AE, A99, AH, AR, AR/A, AR/AE, AR/AH, AR/AO, AR/A1-A30. And anyone in Zone D sits in an undetermined risk zone. Those in A and V zones may have subgrades of risk denoted by another letter or number. Of National Flood Insurance Program claims each year. Those with letter grades of B, C, or X are considered low to moderate risk zones but still account for Zones with a letter grade of A or V are considered high-risk areas with a one in four chance of flooding during a 30-year mortgage period. FEMA Flood Zones ExplainedįEMA gives each zone a letter grade based on the type and likelihood of flooding.
Flood Zones A, AO, A1-A30, AE, A99, AH, AR, AR/A, AR/AE, AR/AH, AR/AO, AR/A1-A30, V1-V30, VE, and V are all SHFAs. Homeowners in a SHFA usually have to get flood insurance if they want a federally-backed mortgage. What Is a Special Flood Hazard Area (SHFA)?įEMA describes some flood zones as Special Flood Hazard Areas. Homeowners should assess their home risk independently and make plans to prepare for flood as needed. The area in question may have a high risk of flooding or may have a low risk. The undetermined risk flood zone simply means that analysis hasn’t been done for the area. The risk of flood in these flood zones is 0.2 percent or less each year. The zone designations for moderate-to-low-risk flood zones are B,C, and X. However, these zones still account for more than 20 percent of flood insurance claims. Moderate-to-low-risk flood zones are areas where flood risk is not as high as Zones A and V. Mortgage companies can only offer loans to homes in SFHAs if the homeowner gets flood insurance. These areas are also called Special Flood Hazard Areas (SFHA). Zone A designates inland flood zones while Zone V indicates coastal areas.
The homes that are in these flood zones are designated with an A or V. High-risk flood zones are at the greatest risk of experiencing a flood. There are low, moderate, and high-risk zones, and flood claims happen in all of them.įlood zones are used to determine flood insurance requirements and costs. Every area is technically a flood zone – it’s just a question of how much flooding may occur. Many homeowners think they only need this coverage in high-risk areas, but in truth, flood insurance is for every one. That’s what flood zones are in a nutshell: shorthand for how likely flooding is in any given area. The Federal Emergency Management Agency (FEMA) maps areas across the country and labels them based on their flood risk or type of flooding.
