ENCROACHMENT AREA is the area that could be used for development, <br /> <br />. The Regulation of Manufactured Housing in the floodplain <br /> <br />The NFIP establishes minimum requirements for manufactured home parks located in floodplains. <br />The minimum elevation is 36 inches above grade. This standard did not protect all residences from the <br />flood levels experienced during Hurricane Fran. The State should therefore continue to encourage <br />communities to adopt standards that exceed minimum NFIP requirements. At a minimum, local ordi- <br />nances should require that new or replacement manufactured homes be installed at or above the <br />flood levels reached during Hurricane Fran, the BFE, or three feet above the highest adjacent grade, <br />whichever is greater. If a manufactured home in a pre-FIRM manufactured home park has been <br />substantially damaged by flooding, the repaired unit or its replacement must be installed at or above <br />the BFE. An elevated manufactured home in a SFHA should be supported by reinforced piers or other <br />foundation systems of equivalent strength that resist floatation, collapse, and lateral movement. Lan- <br />guage in the State's Model Ordinance specifies the use of "reinforced concrete block pier system" as <br />the standard of all manufactured homes in SFHAs. The State has approved the "J. T. William's (Avolis <br />Eng.) Design" as a '10undation system of equivalent strength" for use in lieu of the reinforced concrete <br />block system. <br /> <br />Page 24 <br />
