Would anyone be able to direct me to the right tool or tools that will take a POLYLINE (or polyline raster) overlain with a DEM raster, and obtain a 5 feet HIGHER area than the height of the floodplain boundary?   Many places say to use the Euclidean Allocation tool, but the documentation for that is lacking -in my opinion.  It does not perform the function I'm seeking.
Thank you.
