Floodplain Management

Floods are one of the most common hazards in the United States, however, all floods are not alike. Flood effects can be local, impacting a neighborhood or community, or very large, affecting entire river basins. Some floods develop slowly, over a period of days. Some develop quickly, sometimes in just a few minutes and without any visible signs of rain. Flash floods often have a dangerous wall of roaring water that carries rocks, mud, and other debris and can sweep away most things in its path. Overland flooding occurs outside a defined river or stream.

It is important to be aware of flood hazards regardless of where you live. Even very small streams, gullies, creeks, culverts, dry streambeds, or low-lying ground that appears harmless in dry weather can flood.

This section provides citizens of Henry County with information and resources to familiarize themselves with the subject of flooding, and to become acquainted with the policies and programs related to flooding and floodplain management.
