CFM Floodplain Development & Permitting Flashcards

A Letter of Map Amendment (LOMA) is used to remove a property from the SFHA when the property's lowest adjacent grade is:

Answer: At or above the BFE based on natural ground

A LOMA amends the FIRM to remove a property naturally situated at or above the BFE that was inadvertently included in the SFHA.

What distinguishes a Letter of Map Revision Based on Fill (LOMR-F) from a LOMA?

Answer: A LOMR-F addresses properties elevated by fill; a LOMA addresses naturally elevated properties

A LOMR-F is used when a property has been elevated above the BFE through the placement of fill, while a LOMA applies to land that is naturally above the BFE.

Which zone designation on a FIRM indicates a coastal high-hazard area subject to wave action?

Answer: Zone VE

Zone VE designates coastal high-hazard areas where wave heights of 3 feet or more can occur, requiring more stringent construction standards than Zone AE.

In Zone AO, the required lowest floor elevation for new residential construction is:

Answer: At or above the depth number shown on the FIRM above the highest adjacent grade

In Zone AO, new residential structures must have the lowest floor elevated at or above the designated flood depth above the highest adjacent grade.

A 'substantial damage' determination triggers which requirement for the affected structure?

Answer: Compliance with current floodplain management regulations upon repair

A substantially damaged structure must be brought into full compliance with current floodplain management standards before it can be repaired or rebuilt.

Which of the following accessory structures may qualify for a variance to be constructed below BFE in an SFHA?

Answer: A detached garage used for storage that is non-habitable

Small non-habitable accessory structures such as detached garages used solely for storage may qualify for a variance but must be flood-proofed and anchored.
