Temporary flood insurance is required in Flood Zone AR. Flood depths are expected to range from one to three feet making these areas a required flood insurance zone. These areas still have a one percent chance of flooding each year with a 26 percent chance of flooding over the life of a 30-year mortgage. Flood Zone AOįlood Zone AO is a specific zone for properties located near river or stream flood areas. These are mandatory insurance zones that have BFEs derived at selected intervals on the map. True to Flood Zone A, this area has a 26 percent chance of flooding over the course of a 30-years mortgage. This flooding is generally labeled with the probability of one to three feet of water that pools in areas. Those living in Flood Zone AH also have a one percent annual likelihood of flooding. These are mandatory flood insurance areas.

These areas are subject to a one percent chance of flooding annually. The BFE is used to determine the rate as shown in FEMA’s Flood Insurance Rate Map (FIRM). These zones have a base flood elevation (BFE). 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 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 of its likelihood of experiencing a 100-Year Flood – a flood that has a one percent annual chance of happening. Zone A denotes 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. Those with letter grades of B, C, or X are considered low to moderate risk zones but still account for 20 to 25 percent of National Flood Insurance Program (NFIP) claims each year. 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. Letter Grades and Flood RiskįEMA gives each zone a letter grade based on the type and likelihood of flooding. If your home is in any of these zones and you have a federally backed mortgage, you’re required to have flood insurance. 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.

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 flood insurance in high-risk areas, but that’s not the case. 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.
