Flood Fringe

Flood Fringe is:

  • The portion of the floodplain outside of the floodway
  • Usually contains slow-moving or standing water
  • Occasionally referred to as "floodway fringeā€œ

Development in the flood fringe typically does not interfere with the flow of water.

Floodplain regulations for these areas often allow development to occur; however, elevation and flood proofing is required.

(Floodway) + (Floodway Fringe) = 100 year floodpain (SFHA). Surcharge not to exceed 1.00 feet. Encroachment area is the area that could be used for development.
