How are flood zoned determined?
Flood zones are determined by FEMA who compiles the results of extensive flood studies, and publishes "Flood Insurance Rate Maps" (FIRM). These maps, organized by community (city, town or subsection thereof), indicate those areas which may anticipate flooding conditions and delineate them according to frequency and severity of flooding.
How do I find out if there has been flooding in my subdivision?
The Flood history of your subdivision or neighborhood can be determined by contacting your local Floodplain Administrator.
