Storm Water Services is updating local floodplain maps. The process takes several years and is being done in phases. Among other things, floodplain maps are used to determine who is required to buy flood insurance and which building and remodeling restrictions apply in flood-prone areas.
At this time, the new floodplain maps have NOT taken effect for flood insurance purposes or for all aspects of the regulatory (construction and land development) process.
|Phase 1 - South-central and southeast Charlotte-Mecklenburg (shown on map below in tan) |
Now in Preliminary status - Appeals period has ended. New floodplain maps for this section of Charlotte-Mecklenburg are scheduled to become effective on February 19, 2014. (Please note the new effective date set by FEMA.)
|Phase 2 - Western Charlotte-Mecklenburg (shown on map below in green) |
Now in Draft status - new lines have been drawn and are being reviewed for accuracy.
|Phase 3 - Northeast Charlotte-Mecklenburg and many lakefront properties (shown on map below in yellow)|
Now in Development status - engineering work underway to draw new lines.
Remapping does not have the same effect on all properties. Some properties aren't affected by the new maps. Their flood risk remains the same as before. New mapping data shows other properties have a higher flood risk than before. And some properties are being mapped into lower-risk areas.Frequently Asked Questions
