(a) 
Concrete slab floors of structures proposed in areas of the city where natural topography is significantly lower than the crown of the nearest street or the top of the nearest sanitary sewer manhole shall be constructed to a safe and adequate elevation above the natural ground. Factors determining finished floor elevation shall include condition and elevation of the nearest street, stormwater drainage conditions and highest recorded stormwater level in the location of proposed construction.

(3) 
Unless dry-floodproofed, enclosed areas below the 500-year flood elevation must be equipped with flood openings or vents capable of equalizing water levels and hydrostatic loads. Covers of these openings must not interfere with the equalization of water levels in the event of a flood. A licensed architect or registered professional engineer shall certify the flood openings.
(4) 
Thermal insulation used below the 500-year flood elevation shall be of a type that does not absorb water nor is buoyant.
(5) 
Water heaters, furnaces, air conditioning systems, electrical distribution panels and any other mechanical or electrical equipment must be elevated to at least two feet above the 500-year flood elevation.

All air ducts, pipes, propane tanks and storage tanks located below the 500-year flood elevation shall be anchored to prevent flotation. Tanks and ducts shall be vented to at least two feet above the 500-year flood elevation.
