Flood Zone Details for North Charleston
| Zone | Risk level | Area | Insurance |

| VE | Coastal high-hazard zone with wave action. This is the highest-risk designation -- expect storm surge plus breaking waves. | 1% | Flood insurance is required for federally backed mortgages and is especially important here. |
| A | High-risk flood zone without a detailed BFE study. About a 1-in-100 chance of flooding each year. | 0% | Flood insurance is typically required for federally backed mortgages. |
| X | Lower-risk zone outside the 1% annual chance flood boundary. Flooding is still possible but less likely than in high-risk zones. | 89% | Flood insurance is not required but may still be a smart choice -- nearly one-third of flood claims (29% over 2014-2024) come from lower-risk areas. |
