[Amended 3-27-2023 by Ord. No. 2023-5]
In accordance with Section 312 of the International Building
Code, Utility and Miscellaneous Group U includes buildings and structures
that are accessory in character and miscellaneous structures not classified
in any specific occupancy in the Building Code, including, but not
limited to, agricultural buildings, aircraft hangars (accessory to
a one- or two-family residence), barns, carports, communication equipment
structures (gross floor area less than 1,500 square feet), fences
more than six feet (1,829 mm) high, grain silos (accessory to a residential
occupancy), livestock shelters, private garages, retaining walls,
sheds, stables, tanks and towers.
[Amended 3-27-2023 by Ord. No. 2023-5]
Utility and miscellaneous Group U buildings and structures, including substantial improvement of such buildings and structures, shall be anchored to prevent flotation, collapse or lateral movement resulting from flood loads, including the effects of buoyancy, during conditions up to the Local Design Flood Elevation as determined in Section
19-13.
[Amended 3-27-2023 by Ord. No. 2023-5]
Utility and miscellaneous Group U buildings and structures, including substantial improvement of such buildings and structures, shall be elevated such that the lowest floor, including basement, is elevated to or above the Local Design Flood Elevation as determined in Section
19-13 and in accordance with ASCE 24. Utility lines shall be designed and elevated in accordance with N.J.A.C. 7:13.
[Amended 3-27-2023 by Ord. No. 2023-5]
Fully enclosed areas below the design flood elevation shall be constructed in accordance with Section
19-78 and with ASCE 24 for new construction and substantial improvements. Existing enclosures such as a basement or crawlspace having a floor that is below grade along all adjoining exterior walls shall be abandoned, filled-in, and/or otherwise modified to conform with the requirements of N.J.A.C. 7:13 when the project has been determined to be a substantial improvement by the Floodplain Administrator.
[Amended 3-27-2023 by Ord. No. 2023-5]
Flood-damage-resistant materials shall be used below the Local Design Flood Elevation determined in Section
19-13.
[Amended 3-27-2023 by Ord. No. 2023-5]
Mechanical, plumbing, and electrical systems, equipment and components, heating, ventilation, air conditioning, plumbing fixtures, duct systems, and other service equipment, shall be elevated to or above the Local Design Flood Elevation determined in Section
19-13.
Exception: Electrical systems, equipment and components, and
heating, ventilating, air conditioning, and plumbing appliances, plumbing
fixtures, duct systems, and other service equipment shall be permitted
to be located below the Local Design Flood Elevation provided that
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 flooding to the Local Design Flood Elevation in compliance
with the flood-resistant construction requirements of ASCE 24. Electrical
wiring systems shall be permitted to be located below the Local Design
Flood Elevation provided they conform to the provisions of NFPA 70
(National Electric Code).
