In all areas of special flood hazard, the following standards are required:
All new construction and substantial improvements shall be anchored to prevent flotation, collapse, or lateral movement of the structure.
All manufactured homes shall be anchored to resist flotation, collapse or lateral movement. Methods of anchoring may include, but are not to be 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.
Construction materials and methods.
All new and replacement water supply systems shall be designed to minimize or eliminate the infiltration of floodwaters into the systems;
New and replacement sanitary sewage systems shall be designed to minimize or eliminate the infiltration of floodwaters into the systems and discharge from the systems into floodwaters;
On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding; and
Electrical, heating, ventilation, plumbing and air-conditioning equipment and other service facilities shall be designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.
All subdivision proposals shall be consistent with the need to minimize flood damage;
All subdivision proposals shall have public utilities and facilities such as sewer, gas, electrical, and water systems located and constructed so as to minimize flood damage;
All subdivision proposals shall have adequate drainage provided to reduce exposure to flood damage; and
Base flood elevation data shall be provided for subdivision proposals and other proposed development that contain at least 50 lots or five acres (whichever is less).
All manufactured homes to be placed or substantially improved within an area of special flood hazard shall be elevated on a permanent foundation such that the top of the lowest floor is at or above the base flood elevation.
