All development and building work, including man-made changes
to improved or unimproved real estate for which specific provisions
are not specified in these regulations or the Uniform Construction
Code (N.J.A.C. 5:23), shall:
A. Be located and constructed to minimize flood damage;
B. Meet the limitations of §
158-36A of this chapter when located in a regulated floodway;
C. Be anchored to prevent flotation, collapse or lateral movement resulting from hydrostatic and hydrodynamic loads, including the effects of buoyancy, during the conditions of flooding up to the local design flood elevation determined according to §
158-12;
D. Be constructed of flood-damage-resistant materials as described in
ASCE 24, Chapter 5;
E. Have mechanical, plumbing, and electrical systems above the local design flood elevation determined according to §
158-12 or meet the requirements of ASCE 24, Chapter 7, which requires that attendant utilities are located above the local design flood elevation unless the attendant utilities and equipment are:
(1) Specifically allowed below the local design flood elevation; and
(2) Designed, constructed, and installed to prevent floodwaters, including
any backflow through the system from entering or accumulating within
the components;
F. Not exceed the flood storage displacement limitations in fluvial
flood hazard areas in accordance with N.J.A.C. 7:13; and
G. Not exceed the impacts to frequency or depth of off-site flooding
as required by N.J.A.C. 7:13 in floodways.
Garages and accessory storage structures shall be designed and
constructed in accordance with the Uniform Construction Code.
Fences in floodways that have the potential to block the passage of floodwater, such as stockade fences and wire mesh fences, shall meet the requirements of §
158-36A of these regulations. Pursuant to N.J.A.C. 7:13, any fence located in a floodway shall have sufficiently large openings so as not to catch debris during a flood and thereby obstruct floodwaters, such as barbed-wire, split-rail, or strand fence. A fence with little or no open area, such as a chain-link, lattice, or picket fence, does not meet this requirement. Foundations for fences greater than six feet in height must conform with the Uniform Construction Code. Fences for pool enclosures having openings not in conformance with this section but in conformance with the Uniform Construction Code to limit climbing require a variance as described in Article
VII of this chapter.
Retaining walls, sidewalks and driveways that involve placement of fill in floodways shall meet the requirements of §
158-36A of these regulations and N.J.A.C. 7:13.
Swimming pools shall be designed and constructed in accordance with the Uniform Construction Code. Aboveground swimming pools and below-ground swimming pools that involve placement of fill in floodways shall also meet the requirements of §
158-36A of these regulations. Aboveground swimming pools are prohibited in floodways by N.J.A.C. 7:13.
