River Corridor Protection Area Meander Belt = River Corridor Protection Area River Corridor Protection Area Meander Belt indicates the space needed by the river to achieve a vertically stable least erosive slope River Corridor Protection

SLIDE 1

Meander Belt = River Corridor Protection Area

River Corridor Protection Area

SLIDE 2

Meander Belt indicates the space needed by the river to achieve a vertically stable least erosive slope

River Corridor Protection Area

SLIDE 3

Development encroaches up to the edge of the meander belt

River Corridor Protection Area

SLIDE 4

River Corridor Protection Area

Channel management will limit meander migration before river gets out to edge of the meander belt

Black Lines = Bank Armoring to Protect new structures

SLIDE 5

Opportunity lost to achieve a least erosive slope River confined and still energized – erosion hazards not minimized

From FEH to River Corridors

Black Lines = Bank Armoring to Protect new structures

SLIDE 6

River Corridor adds 50’ to each side of the Meander Belt

River Corridors

SLIDE 7

River Corridor adds 50’ to each side of the Meander Belt Provides space for stable boundary conditions and stable meander geometry Erosion hazards minimized
