designed to minimize or eliminate infiltration of floodwaters into
the system and be located and constructed to minimize or eliminate
flood damages.
E.
Streets. The finished elevation of proposed new streets shall be
no more than one foot below the regulatory flood elevation.
F.
Utilities. All utilities such as gas lines, electrical and telephone
systems being placed in an identified floodplain area should be located,
elevated (where possible) and constructed to minimize the chance of
impairment during a flood.
G.
Storage. All materials that are buoyant, flammable, explosive or, in times of flooding, could be injurious to human, animal or plant life, and not listed in § 210-23, Development which may endanger human life, shall be stored at or above the regulatory flood elevation and/or floodproofed to the maximum extent possible. Enclosed areas below the lowest floor (including basement) are prohibited.
[Amended 2-27-1991]
H.
Placement of buildings and structures. All buildings and structures
shall be designed, located and constructed so as to offer the minimum
obstruction to the flow of water and shall be designed to have a minimum
effect upon the flow and height of floodwater.
I.
Anchoring.
(1)
All buildings and structures shall be firmly anchored in accordance
with accepted engineering practices to prevent flotation, collapse
or lateral movement.
(2)
All air ducts, large pipes, storage tanks, and other similar objects
or components located below the regulatory flood elevation shall be
securely anchored or affixed to prevent flotation.
J.
Floors, walls and ceilings.
(1)
Wood flooring used at or below the regulatory flood elevation shall
be installed to accommodate a lateral expansion of the flooring, perpendicular
to the flooring grain, without causing structural damage to the building.
(2)
Plywood used at or below the regulatory flood elevation shall be
of a marine or water-resistant variety.
(3)
Walls and ceilings at or below the regulatory flood elevation shall
be designed and constructed of materials that are water-resistant
and will withstand inundation.
(4)
Windows, doors and other components at or below the regulatory flood
elevation shall be made of metal or other water-resistant material.
K.
Paints and adhesives.
(1)
Paints or other finishes used at or below the regulatory flood elevation
shall be of marine or water-resistant quality.
(2)
Adhesives used at or below the regulatory flood elevation shall be
of a marine or water-resistant paint or other finishing material.
