New and replacement electrical, heating, plumbing, ventilation and
air conditioning equipment, appliances, fixtures and components, HVAC
duct work and duct systems, and any other utility service equipment,
facilities, machinery, or connections servicing a structure, shall
be elevated so that the bottom of each shall be elevated one (1.0)
foot above the base flood elevation (BFE). This includes, but is not
limited to, furnaces, oil or propane tanks, air conditioners, heat
pumps, hot water heaters, ventilation duct work, washer and dryer
hook-ups, electrical junction boxes, and circuit breaker boxes. Systems,
fixtures, equipment and components shall not be mounted on or penetrate
through breakaway walls intended to fail under flood loads. Connections
or other equipment that must be located below the BFE plus 1.0 foot
elevation are permitted only when no other elevation alternative is
available and provided they are designed and installed to prevent
water from entering or accumulating within the components and to resist
hydrostatic and hydrodynamic loads and stresses, including the effects
of buoyancy, during the occurrence of the base flood event. Electrical
wiring systems that must be located below the BFE plus one (1.0) foot
shall conform to the standards for wet locations.
