I am trying to have a complete set of FEMA flood data for an in-house project. Is there a source url to download the FEMA DFIRM as GIS data for all of United States? 

Thank you.

This link does not exist. Is there a new one? It seems that the NFHL GIS data is no longer available to download directly.

National Flood Hazard Layer (NFHL) | FEMA.gov  says " Technical GIS users can also utilize a series of dedicated GIS web services that allow the NFHL database to be incorporated into websites and GIS applications." and provides this link:

FEMA: Mapping Information Platform: NOPAGETAB_NFHLWMS   

But as far as I can tell, that just send you to a map viewer, and download to an image or pdf.  However, buried in the fine print is:

For more information, please call or email a FEMA Map Specialist at 1-877-FEMA-MAP or FEMAMapSpecialist@riskmapcds.com.

OMG THANK YOU!!!! I don't know why every link I was finding was either outdated or didn't have download capabilities. It appears even the WMS links are outdated. Thanks so much !!

Not exactly the same dataset but would this work for your purposes? I use it as an input for a classification model.
