Flood Zone - Any information on a Letter of Map Amendment (LOMA)?

[Cameron O'Connor]

Flood Zone's are often talked about as the hatred zone. The no-go zone. But I've recently been reading about FEMA's Letter of Map Amendment (LOMA). Has anyone been issued a LOMA? How was the process? Is there any possibility that a surveyor could determine you're in a higher risk zone that originally quoted and drive the premium up? Any insight into the process would be helpful. Thanks!
