G. REFLECT & DISCUSS The 1996 FEMA FIRM for Montezuma, Georgia, shows hazard areas designated zone A. Zone A is
the official designation for areas expected to be inundated by 100-year flooding even though no BFEs have been determined.
The location of zone A (shaded gray) is shown on the Flood Hazard Map of a portion of the Montezuma, GA 7.5 minute
map below. Your work above can be used to revise the flood hazard area. Place a dark line on this map (as exactly as you
can) to show the elevation contour of the BFE for this community (your answer in item F). Your revised map reflects more
accurately what area will be inundated by a 100-year flood. In general, how is the BFE line that you have plotted different
from the boundary of zone A plotted by FEMA on its 1996 FIRM?
