The general requirements of this article apply to all development proposed within all special flood hazard
areas identified in § 14:3-5.
A.
In all flood zones:
(1)
Subdivision proposals and development proposals
shall be consistent with the need to minimize flood damage and are subject to all applicable standards in these regulations.
(2)
Subdivision proposals and development proposals
shall have utilities and facilities such as sewer, gas, electrical,
and water systems located and constructed to minimize flood damage.
(3)
Subdivision proposals and development proposals
shall have adequate drainage paths provided to reduce exposure to flood hazards and to guide floodwaters around and away from
proposed structures.
(4)
Subdivision proposals and development proposals
that are wholly or partially in flood hazard areas
where base flood elevation data are not provided
by the Floodplain Administrator or available from other sources, shall
be supported by determinations of base flood elevations as required in § 14:3-19 of these regulations.
B.
In special flood hazard areas of nontidal waters of the state. Subdivision proposals shall be laid out such that proposed building
pads are located outside of the special flood hazard area and any portion of platted lots that include land areas that are
below the base flood elevation shall be used for
other purposes, deed restricted, or otherwise protected to preserve
it as open space.
A.
New and replacement water supply systems shall be designed to minimize
or eliminate infiltration of floodwaters into the systems.
B.
New and replacement sanitary sewage systems shall be designed to
minimize or eliminate infiltration of floodwaters into systems and
discharges from systems into floodwaters.
C.
On-site waste disposal systems shall be located to avoid impairment
to or contamination from them during conditions of flooding.
New building and structures (including the
placement and replacement of manufactured homes)
and substantial improvement of existing structures (including manufactured homes) that are located,
in whole or in part, in any special flood hazard area shall:
A.
Be designed (or modified) and constructed to safely support flood loads. The construction shall provide a complete load
path capable of transferring all loads from their point of origin
through the load-resisting elements to the foundation. Structures shall be designed, connected and anchored to resist flotation, collapse
or permanent lateral movement due to structural loads and stresses,
including hydrodynamic and hydrostatic loads and the effects of buoyancy,
from flooding equal to the flood protection
elevation or the elevation required by these regulations
or the building code, whichever is higher.
B.
Be constructed by methods and practices that minimize flood damage.
D.
Have electrical systems, equipment and components, and mechanical,
heating, ventilating, air conditioning, and plumbing appliances, plumbing
fixtures, duct systems, and other service equipment located at or
above the elevation of the lowest floor required in § 14:3-41A or 14:3-42A (A Zones), § 14:3-49B (Coastal A Zones) or 14:3-56B (V Zones). Electrical
wiring systems are permitted to be located below the elevation of
the lowest floor provided that they conform to the
provisions of the electrical part of the building code for wet locations. If replaced as part of a substantial
improvement, electrical systems, equipment and components,
and heating, ventilation, air conditioning, and plumbing appliances,
plumbing fixtures, duct systems, and other service equipment shall
meet the requirements of this section.
E.
If located in flood hazard areas (A Zones) that
are not identified as Coastal A Zones and coastal high hazard areas (V Zones), comply with the specific requirements of Article V.
G.
If located in coastal high hazard areas (V Zones), comply with the specific requirements of Article VII.
H.
Comply with the requirements of the most restrictive designation
if located on a site that has more than one flood zone designation (A Zone, designated floodway, Coastal A Zone, V Zone).
Repair, alteration, addition, rehabilitation, or other improvement
of historic structures shall be subject to the requirements
of these regulations if the proposed work is determined to be a substantial improvement, unless a determination is made
that the proposed work will not preclude the structure's continued designation as an historic structure. The Floodplain Administrator may require documentation of a structure's continued eligibility and designation as
an historic structure.
A.
New manufactured homes shall not be placed or installed
in floodways or coastal high hazard areas (V Zones).
B.
For the purpose of these regulations, the lowest floor of a manufactured home is the bottom of the lowest
horizontal supporting member (longitudinal chassis frame beam).
C.
New manufactured homes located outside of floodways and coastal high hazard areas (V Zones), replacement manufactured homes in any flood hazard areas, and substantial improvement (including repair of substantial damage) of existing manufactured homes in all flood hazard
area, shall:
(2)
Be installed in accordance with the anchor and tie-down requirements
of the building code or the manufacturer's written
installation instructions and specifications; and
(3)
Have enclosures below the lowest floor of the
elevated manufactured home, if any, including enclosures that are surrounded by rigid skirting or other material that is attached to the frame or foundation, that comply with the requirements of Article V or Article VI, as applicable to the flood zone.

[NOTE: See "Protecting Manufactured Homes from Floods and Other
Hazards: A Multi-Hazard Foundation and Installation Guide" (FEMA P-85).]
|
Recreational vehicles shall:
Critical and essential facilities shall:
A.
Not be located in coastal high hazard areas (V Zones), Coastal A Zones or floodways.
B.
If located in (flood hazard areas other than coastal high hazard areas,) Coastal A Zones or floodways, be elevated to the higher of elevation
required by these regulations plus one foot, the elevation required
by the building code, or the elevation of the two-tenths-percent
chance (five-hundred-year) flood.
A.
Underground tanks in flood hazard areas shall be
anchored to prevent flotation, collapse or lateral movement resulting
from hydrostatic loads, including the effects of buoyancy, during
conditions of the base flood.
B.
Aboveground tanks in flood hazard areas shall be
anchored to a supporting structure and elevated to
or above the base flood elevation, or shall be anchored
or otherwise designed and constructed to prevent flotation, collapse,
or lateral movement resulting from hydrodynamic and hydrostatic loads,
including the effects of buoyancy, during conditions of the base flood.
C.
In flood hazard areas, tank inlets, fill openings,
outlets and vents shall be:
(1)
Fitted with covers designed to prevent the inflow of floodwater
or outflow of the contents of the tanks during conditions of flooding; and
(2)
Anchored to prevent lateral movement resulting from hydrodynamic
and hydrostatic loads, including the effects of buoyancy, during conditions
of the base flood.
Applications for functionally dependent uses that do not conform to the requirements of these regulations shall
be approved only by variances issued pursuant to Article VIII. If approved, functionally dependent uses shall be protected by methods that minimize flood damage during the base flood, including measures
to allow floodwaters to enter and exit, use of flood damage-resistant
materials, and elevation of electric service and equipment
to the extent practical given the use of the building.
