Has anyone ever found a place to get flood lines in SHP format, specifically in Florida and Georgia?
You can download FIRMs from FEMA and they will import into cad at the correct location, but you still don't have linework.

try here:

or if it is a specific county let me know

This is perfect. Thank you, Michael.

Am I missing something with the layers?
If you bring in the S_FLD_HAZ_LN file, it draws in flood lines, but there isn't a property in the table specifying the zone.

This is mentioned in the metadata file, but not included in the download, and I can't find online.

<enttypd>Location and attributes for leader lines for labels shown on the FIRM.</enttypd>
<enttypds>FEMA FIRM Database Technical Reference (available on the FEMA Risk MAP Knowledge Sharing Site).</enttypds>

I went here:
http://fema.maps.arcgis.com/home/webmap/viewer.html?webmap=cbe088e7c8704464aa0fc34eb99e7f30 (http://fema.maps.arcgis.com/home/webmap/viewer.html?webmap=cbe088e7c8704464aa0fc34eb99e7f30)
zoomed in....Rt-clicked and selected DOWNLOAD county GIS data
pulled in the shp files and got the following layers/data tables
-
I'm dumb, it's a separate file for just the zone labels.
S_FLD_HAZ_LN = linework
S_FLD_HAZ_AR = labels
Thank you, Michael.

I've been around awhile +a day

FEMA seems to have changed something and while you can download a FIRM panel, I can no longer find where it will let you download SHP files.
Has anyone had any luck getting such files recently?
-
SHP files are not available for the entire USA
