North Carolina Floodplain Mapping Program
We don't even live within a floodplain, but you'd be hardpressed to know that looking at our basement or one corner of the backyard.
Even if you are not in a floodplain you may experience flooding. Area drainage problems may cause flooding on local streets and in residential neighborhoods. Inundation flooding occurs when the amount of rainfall and runoff exceeds a storm water system’s (ditch or sewer) capability to remove it.
