(A) Generally. In all areas of special flood hazards, the following provisions are required for all new construction and substantial improvements.
(Prior Code, § 8-51)
(B) Anchoring.
(1) All new construction and substantial improvements shall be anchored to prevent flotation, collapse or lateral movement of the structure and capable of resisting the hydrostatic and hydrodynamic loads.
(2) All manufactured homes must be elevated and anchored to resist flotation, collapse or lateral movement and capable of resisting the hydrostatic and hydrodynamic loads. Methods of anchoring may include, but are not limited to use of over-the-top or frame ties to ground anchors. This requirement is in addition to applicable state and local anchoring requirements for resisting wind forces. Specific requirements may be:
(a) Over-the-top ties be provided at each of the four corners of the manufactured home, with two additional ties per side at intermediate locations, with manufactured homes less than 50 feet long requiring one additional tie per side;
(b) Frame ties be provided at each corner of the home with five additional ties per side at intermediate points, with manufactured homes less than 50 feet long requiring four additional ties per side;
(c) All components of the anchoring system be capable of carrying a force of 4,800 pounds; and
(d) Any additions to the manufactured home be similarly anchored.
(Prior Code, § 8-52)
(C) Construction materials and methods.
(1) All new construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage.
(2) All new construction and substantial improvements shall be constructed using methods and practices that minimize flood damage.
(3) All new construction and substantial improvements shall be constructed with electrical, heating, ventilation, plumbing and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.
(Prior Code, § 8-53)
(D) Utilities.
(1) All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of floodwaters into the system.
(2) New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltrations of floodwaters into the systems and discharge from the systems into floodwaters.
(3) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding.
(Prior Code, § 8-54)
