In all areas of special flood hazard, the following standards are required:
(a) Anchoring.
(1) All new construction and substantial improvements shall be anchored to prevent flotation, collapse or lateral movement of the structure.
(2) All mobile homes shall be anchored to resist flotation, collapse or lateral movement by providing over-the-top and frame ties to ground anchors. Specifically:
A. Over-the-top ties shall be provided at each of the four corners of the mobile home, with two additional ties per side at intermediate locations. For mobile homes less than fifty feet long, only one additional tie per side is required.
B. Frame ties shall be provided at each corner of the mobile home with five additional ties per side at intermediate points. For mobile homes less than fifty feet long, only four additional ties per side are required.
C. All components of the anchoring system shall be capable of carrying a force of 4,800 pounds.
D. Any addition to the mobile home shall be similarly anchored.
(b) 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.
(c) Utilities.
(1) All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the systems and discharge from the systems into flood waters.
(2) New and replacement sanitary sewerage systems shall be designed to minimize or eliminate infiltration of flood waters into the systems and discharge from the systems into flood waters.
(3) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding.
(d) Subdivision Proposals.
(1) All subdivision proposals shall be consistent with the need to minimize flood damage.
(2) All subdivision proposals shall have public utilities and facilities, such as sewer, gas, electrical and water systems, located and constructed to minimize flood damage.
(3) All subdivision proposals shall have adequate drainage provided to reduce exposure to flood damage.
(4) Base flood elevation data shall be provided for subdivision proposals and other proposed developments which contain at least fifty lots or five acres, whichever is less.
