Application for a floodplain development permit shall be made on forms furnished by the Floodplain Administrator and may include, but not be limited to, plans in duplicate drawn to scale showing the nature, location, dimensions and elevations of the area in question; existing or proposed structures, fill, storage of materials, drainage facilities; and the location of the foregoing. Specifically, the following information is required:
1. 
Elevation in relation to mean sea level of the lowest floor (including basement) of all structures.
2. 
Elevation in relation to mean sea level to which any non-residential structure is to be flood-proofed.
3. 
Provide certification from a registered, professional engineer or architect that the non-residential flood proofed structure will meet the flood proofing criteria in Article V, Section 415.190(A)(2).
