Can plans for a floodproofed warehouse with movable shields be approved assuming adequate warning time exists?

The correct choice emphasizes the importance of having proper certification for floodproofed structures. When it comes to floodplain management, especially under the National Flood Insurance Program (NFIP), floodproofing strategies must follow specific criteria and be certified by a qualified professional. This ensures the plans adhere to engineering standards that demonstrate their effectiveness in mitigating flood risks.

In the context of a warehouse equipped with movable shields, having a certification verifies that the design is capable of withstanding potential flood conditions as long as there is adequate warning time. It also ensures that the building can be temporarily protected from floods without compromising overall safety and integrity.

Proper certification confirms that the floodproofing measures meet the community's floodplain management regulations and NFIP criteria, thus enabling the plans to be approved. This approach aligns with the NFIP's goals of reducing flood risk and protecting property.

While considering that a warehouse may need to be located above the Base Flood Elevation (BFE) or have other specific site modifications, these aspects do not negate the necessity for a certification which it must obtain to be compliant and effectively manageable under flood risks.
