Flood Hazard Boundary maps (FHBMs) are printed on a much smaller 11"x17" sheet of paper than the FBFM or FIRM map panels which measure about 2’x3'.

A FIRM or FBFM map set contains one or more of the 2’x3’ panels. These panels are folded like a highway map (known as a “Z” fold map). Each flood map panel has a legend printed on it.

When a community’s map set contains more than one panel, it will be accompanied by a flood map Index panel.
