Floodplain Management
Reducing Flood Damage
With over 300 miles of rivers and unnamed streams located within Nicollet County, the potential of flooding and the damage that results from it can be devastating. Floodplain is the low, flat, periodically flooded lands adjacent to rivers, streams, and lakes that are subject to land shaping and water flow processes.
The floodplain consists of:
- Floodway – Land immediately adjoining the river channel that is the natural conduit for flood waters.
- Flood Fringe – Remainder of the floodplain lying outside of the floodway. This area is generally covered by shallow, slow-moving flood waters.
- General floodplain areas – Areas outside of the floodway and flood fringe and below the .2% (500 yr.) floodplain.
Limiting Various Activities
Floodplain management incorporates a community’s actions for reducing flood damage. Construction, development, and use activities within the various areas of floodplain may be limited.
