How to change Your Flood Zone Designation
Updates to flood maps are a collaboration between your community and FEMA. Every community that participates in the National Flood Insurance Program has a floodplain administrator who works with FEMA during the mapping process.
FEMA provides the technology and relies on your community’s leaders to share local knowledge and plans to make the maps as accurate as possible.
- FEMA and the floodplain administrator work with local engineers and surveyors to collect the data to inform the maps.
- Community members are also invited to provide information to help local officials better understand how water drains in the area.
- FEMA works with local experts before combining the data into a computer model that is used to create the updated flood map.
Once the data analysis is done, preliminary flood maps will be available for review. Before your community decides to adopt the maps, you have 90 days to submit technical data to support an appeal to the map.
Any time after your community adopts the maps, you can submit data to amend or revise the flood map through the Letter of Map Change (LOMC) process.
