Floodplains and Fences in Charlotte
How mapped floodplains affect fences, and why open designs survive floods better.
Fences in mapped floodplains in Charlotte-Mecklenburg can be limited because they can block floodwater and catch debris. Development in regulated floodplain areas may require review, and solid fences are the most likely to be restricted. Check floodplain maps and with Charlotte-Mecklenburg Storm Water Services before building.
Why it matters
When creeks rise, solid fences trap water and debris, can redirect flow onto neighbors and often fail. Charlotte-Mecklenburg Storm Water Services manages floodplains and has bought out flood-prone homes along several creeks.
Before you build
- Check floodplain maps for your lot.
- Contact Storm Water Services if any part of the fence is in the mapped floodplain.
- Choose an open design if fencing is allowed.
- Keep gates away from the lowest areas.
Flood-prone areas
Low areas near creeks such as Briar, Little Sugar, McAlpine, Irwin and others have mapped floodplains. Many affected lots are in established neighborhoods.

Questions Charlotte homeowners ask
How do I check if I'm in a floodplain?
Look at the county’s floodplain maps (available through Polaris and stormwater resources) or ask Storm Water Services.
Which fences hold up in floods?
Open fences like aluminum or chain link let water pass. Solid fences act like dams and are often pushed over.
