As floodplain maps are updated for more of Charlotte-Mecklenburg, the new data will be shown on the 3D Floodzone Map.
Extra colors give you extra information
If the 3D Floodzone Map comes up in red and yellow, the new mapping data is available for that watershed. If the map is in blue and gray, the map is accurate but does not yet show flood depths or the property’s chance of flooding in any given year.
Floodzone maps don't tell the whole story
Floodplain maps only show certain types of flood risk. The maps show flood risk for land along major creeks that has at least a one percent chance of flooding in any year. Flooding can and does happen outside of mapped floodplains, such as in low-lying areas.
Remember: anywhere it rains, it can flood.
