HI folks,

A colleagueI recently had a need to check if a property was in a flood
plain, and actually the easiest way he could find to do that was to use the
TNM Viewer.

FEMA has updated flood maps for much of the country, but they're kind of
difficult to use or access online.  The FEMA map service is listed in TNM
Viewer under "Natural Hazards" and "FEMA Flood Hazards" at the bottom left
of the viewer.

So bring up that pane in the table of contents, activate the hazards theme,
and type the address of interest into the search box at the top of the
viewer.  Hit 'Zoom to' on the selection, and you'll zoom in close enough to
show the flood maps.  You may need to turn on the flood layers you want to
see and/or zoom in or out a bit depending on where you are.

It's also handy to be able to show the imagery and set the flood layer to
about 50% transparency - then you can view if the structure is in the flood
zone or just the property.

Give it a shot, amaze your friends and stakeholders
