Storm Water Services is updating local floodplain maps. New maps for the Little Sugar Creek and Briar Creek watersheds will be available in the spring of 2010.

Public meetings will be held in 2010 to explain the proposed maps and help residents understand any changes. Check this web page for meeting dates and times.

Floodplain maps for other Charlotte-Mecklenburg watersheds will be revised in the future.

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.

What are floodplain maps used for?

What's the difference between the FEMA Floodplain and Community Floodplain?

Can I build or renovate in the floodplain?

Who should buy flood insurance?
