Frequently Flooded Areas

Frequently flooded areas - also known as Special Flood Hazard areas and Floodplains/Floodways - pose a risk to public and private property and public health. Regulation of these lands protects human life. It also minimizes loss and the need for rescue and relief when flooding occurs.
