The general requirements of this article apply to all development proposed within special flood hazard areas identified in §
159-5.
All new construction of buildings and structures, including
placement of manufactured homes and substantial improvements to existing
buildings and structures, that are to be located, in whole or in part,
in special flood hazard areas shall meet the following requirements:
A. Be designed (or modified) and constructed to safely resist 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. Buildings and structures shall be designed,
connected and anchored to resist flotation, collapse or permanent
lateral movement due to structural loads and stresses from flooding
equal to the design flood elevation, including hydrodynamic and hydrostatic
loads and the effects of buoyancy.
[Amended 9-19-2014 by Ord. No. 0914-02]
B. Be constructed by methods and practices that minimize flood damage.
C. Use flood damage-resistant materials below the base flood elevation
plus one foot.
[Amended 9-19-2014 by Ord. No. 0914-02]
D. Have electrical systems, equipment and components, and heating, ventilating,
air-conditioning, and plumbing appliances, plumbing fixtures, duct
systems, and other service equipment that are located at or above
the base flood elevation plus one foot. Electrical wiring systems
are permitted to be located below the base flood elevation plus one
foot, provided they conform to the provisions of the electrical part
of this 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. As an alternative to §
159-21D, electrical systems, equipment and components, and heating, ventilating, air-conditioning, and plumbing appliances, plumbing fixtures, duct systems, and other service equipment are permitted to be located below the base flood elevation plus one foot, 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 the base flood.
F. In all special flood hazard areas other than coastal high-hazard areas (A Zones), meet the specific requirements of Article
IV.
G. In all coastal high-hazard areas (V Zones), meet the specific requirements of Article
V.
H. In a special flood hazard area with more than one designation (A
Zone, floodway, V Zone), meet the requirements of the most restrictive
designation.
[Amended 9-19-2014 by Ord. No. 0914-02]
Repair, alteration, or rehabilitation of historic structures shall be subject to the requirements of these regulations unless a determination is made that compliance with these regulations will preclude the structure's continued designation as a historic structure and a variance is granted in accordance with §
159-36 and such variance is the minimum necessary to preserve the historic character and design of the structure.
