What is the criteria to change flood zone of a property

[Weng L.]

I am buying a new construction at flood zone AH. I learned that if the property meets certain criteria, you can request FEMA to remove it from high risk flood zone. But I can't find what criteria needs to be met in order to have FEMA change its flood zone. Any one done it before?

The property has a Base Flood Elevation 7 ft (item B9 in Elevation Certificate). The measurement numbers provided by surveyor are shown in attached photo 

I have heard different information from different builders. One said that as long as Top of bottom floor is above FEMA requirement 8 ft, flood insurance is not required by lender automatically even if the property is in FEMA high risk flood zone. I doubt it is as simple as that
