Abstract:
A 1% Annual Chance Flood Depth Grid represents the height of a 100 year flood surface elevation above ground or bottom of a stream channel measured in feet.  The values are captured per cell of a defined area.  The cell size for 1% Annual Chance Flood Depth Grids is variable.  It is calculated by subtracting the height of the ground surface elevation from the surface height of the 1% annual chance flood.  A Flood Depth Grid can assist a community in understanding, communicating, and relaying the variability and severity of flooding in a mapped floodplain.
