Floodplains are the areas along streams or rivers that are likely to experience repeated flooding.
Over thousands of years, nature shaped the floodplain to hold excess water that spills over the banks. Simply put, floodplains are meant to flood.
Decades ago, homes and buildings were often built in floodplains in Charlotte and across the nation. That's because:
- water was easily available for drinking or commercial uses
- floodplain land is often flat and easier to develop than hilly land.
Since the late 1970s, building in local floodplains has been restricted. Protecting floodplains from additional development can reduce flood
losses and improve the environment.
