Updated Charlotte-Mecklenburg Floodplain Maps
|
|
Storm Water Services is updating local floodplain maps. The process takes several years.
Draft floodplain maps are available now for central and southeastern Charlotte-Mecklenburg. This includes:
- McAlpine
- McMullen
- Four Mile
- Six Mile
- Clem
- Crooked
- Back
|
- Reedy
- McKee
- Caldwell
- Clear and
- Goose
- Little Sugar and
- Briar Creek watersheds.
|
 |
See the draft floodplain maps for the watersheds listed above.

Next steps:
The new floodplain maps for:
- Briar/Little Sugar (shown on the map in pink)
- McAlpine/Goose (shown on map in blue)
are now being reviewed by the Federal Emergency Management Agency (FEMA) for accuracy.
During this review, the maps are defined as "preliminary." This means the new maps are not being used yet for flood insurance or regulatory (construction and land development) purposes.

FEMA approval expected in 2013
FEMA's map review and mandatory appeals period will likely take at least a year. During that time, existing (old) maps will be used for insurance and regulatory purposes.
If you have questions about the status of the preliminary maps or how your property is affected, call 704-432-RAIN (7246).
FEMA approval of the floodplain maps for the Briar/Little Sugar and the McAlpine/Goose watersheds is expected in 2013. After FEMA approval, the new floodplain maps will take effect for both insurance and regulatory purposes.
In the meantime, floodplain remapping and public review will begin for Charlotte-Mecklenburg’s remaining watersheds.

Why do floodplain maps change?
Flood risks change because of
- development
- population changes
- local projects to manage storm water.
Mapping technology has improved since the last maps were drawn ten years ago. Those advancements allow Storm Water Services to more accurately predict where floodwater is likely to flow. The new maps will also calculate how deep floodwater is likely to get.
