Considering that there is some sort of problem it may be best to view them locally at whatever municiplaity is involved. That's where all of the maps originate from anyway.
All of the engineering work, preliminary maps, and appeals are handled on the local level. So the local municipality does most of the work prior to FEMA actually adopting and publishing the FIRMs.
I've had no problems viewing the Knox maps. Most that I have seen are dated 2007 though.
