Flood Insurance - Anyone successful filing for Map Amendment?

[Erick Sembrano]

FYI: Will repost this in the Property Insurance Category since I did not get any comments when this was posted in my local area. 

We have a multifamily property that is in a designated A14 for flood zone and as such in a higher risk of flooding needing a flood insurance. We did not get a certificate of elevation via land survey before we bought this property. Wondering if anyone has been successful in getting a LOMA (Letter of Map Amendment) to FEMA (if the certificate of elevation supports it) and changed their designation out of the flood zone?

Looking forward to hear about others experiences. Thanks!
