Local officials use floodplain maps to make sure new construction meets the requirements of floodplain regulations. Mortgage and insurance companies use the maps to determine the risk of financing or insuring buildings in or near the floodplain.

Two floodplains
In 2000, Charlotte-Mecklenburg became the first community in the nation to show both the current and future floodplain on its official maps.
Mecklenburg County's floodplain maps accurately show the locations along major streams and creeks where flooding is more likely to occur now. Charlotte-Mecklenburg decided to go a step further and determine what areas will be prone to flooding in the future—once land upstream is paved and built upon.
These locations are known as the Future Floodplain or Community Floodplain. Because of its potential to flood in the future, there are restrictions on grading, building renovations or new construction in the Community Floodplain.

Current maps have been used since 2000. FEMA approved Charlotte-Mecklenburg's floodplain maps in 2004.
- Remapping began in 1999
- Cost $2 million
- 60% of remapping paid by Storm Water Services fees
- 40% of remapping paid by federal and state sources
Charlotte-Mecklenburg began updating floodplain maps in 2010. Until the new maps are formally approved, the 2000 maps remain in effect.
