Natural & Beneficial Functions of the Floodplain
Wetland areas and buffer areas adjacent to open spaces help reduce flood damage because floodwaters in a natural floodplain are permitted to spread over a large area and open spaces provide flood water storage.  It is our job to help preserve natural areas.  These natural areas also filter nutrients and impurities from stormwater runoff and promote infiltration and aquifer recharge.  By preserving natural areas, fish and wildlife habitats are protected to provide breeding and feeding grounds. The Village of Wellington is proud to have approximately 6,000 acres of open space in the Special Flood Hazard Area.
Some Natural Functions of Floodplains
Natural Flood and Erosion Control
- Provide flood storage and conveyance
- Reduce flood velocities
- Reduce peak flows
- Reduce sedimentation
Water Quality Maintenance
- Filter nutrients and impurities from runoff
- Process organic wastes
- Moderate temperature fluctuations
Groundwater Recharge
- Promote infiltration and aquifer recharge
- Reduce frequency and duration of low surface flows
Biological Productivity
- Promote vegetative growth through rich alluvial soils
- Maintain biodiversity
- Maintain integrity of ecosystems
Fish and Wildlife Habitats
- Provide breeding and feeding grounds
- Create and enhance waterfowl habitat
- Protect habitats for rare and endangered species
