and Construction Guidance for Breakaway Walls.")
[4]
Electrical, mechanical, and plumbing system components shall
not be mounted on or penetrate through walls that are designed to
break away under flood loads.
[5]
Walls intended to break away under flood loads shall be constructed
with insect screening or open lattice, or shall be designed to break

The walls and partitions below the lowest floor
have been designed to collapse from a water load less than that which
would occur during the base flood.
[b]
The elevated portion of the building and supporting
foundation system have been designed to withstand the effects of wind
and flood loads acting simultaneously on all building components (structural
and nonstructural). Water loading values used shall be those associated

[3]
A horizontal addition to a building or structure that is not
substantial improvement is not required to comply with this section.
(5)
Accessory structures.
(a)
Accessory structures shall be limited to not more than 200 square
feet in total floor area.
(b)
Accessory structures shall comply with the elevation requirements
and other requirements of Section 6.3[3] or, if not elevated, shall:

A deck or patio that has a vertical thickness of more than 12
inches or that is constructed with more than the minimum amount of
fill that is necessary for site drainage shall not be approved unless
an analysis demonstrates no harmful diversion of floodwaters or wave
runup and wave reflection that would increase damage to adjacent elevated
structures.
[4]
A deck or patio that has a vertical thickness of 12 inches or
less and that is at natural grade or on fill material that is similar
to and compatible with local soils and is the minimum amount necessary
for site drainage may be approved without requiring analysis of the
impact on diversion of floodwaters or wave runup and wave reflection.
