What is a flood zone?
A flood zone is an area designated on the Flood Insurance Rate Map (FIRM) that is provided to the City of Norfolk by FEMA. This map shows the risks that properties have of being impacted by flooding.
What are the flood zones?
The City of Norfolk has multiple flood zones that are shown on our maps. These zones were determined scientifically using a study that predicts where water will go during major flooding events (one percent (1%) annual chance of flooding).
These zones are:
- X Zone
- Areas that are outside the 0.2% annual chance of flooding. This zone is the least likely to flood.
- X (0.2% annual chance of flood) Zone
- Areas that have a 0.2% annual chance of flooding and may see flooding if the flood event is abnormally large. Areas are subject to flooding depths less than 1 foot during a 1% chance flood.
- AE Zone
- Areas subject to a 1% annual chance flooding event with water elevation levels determined (Base Flood Elevation). This area is most likely to flood during a flood event.
- AH Zone
- Areas subject to a 1% annual chance flooding event caused by ponding water. Elevations determined.
- AO Zone
- Areas subject to a 1% annual chance flooding with flood depths between 1 to 3 feet. Usually occurs due to sloping terrain
- VE Zone
- Velocity zone. Area subject to wave heights 3 feet or more and extending to the inward limit of the Coastal Primary Sand Dune
- Limits of Moderate Wave Action: Area affected by waves heights between 1.5 and 3 feet
What flood zones require flood insurance?
Normally, flood insurance is required by lenders for properties located within higher risk flood zones (AE, AH, AO and VE). In the City of Norfolk, the chance of flooding is real for everyone with our risk coming from both coastal and rain event flooding. It is recommended to obtain flood insurance even if it is not required to have it.

What is the Community Rating System (CRS)?
The City of Norfolk participates in the CRS program which provides a reduction in flood insurance rates for the citizens of Norfolk. By participating in this program, we provide better protection to people and property by enforcing higher development standards, providing public outreach and information, maintaining the city's drainage system, and other efforts.
