iii. The fill shall be protected against erosion and scour during flooding by <br />vegetative cover, riprap, or bulkheading. If vegetative cover is used, the <br />slopes shall be no steeper than 3 horizontal to 1 vertical. <br />iv. The fill shall not adversely affect the flow of surface drainage from or onto <br />neighboring properties. <br />v. The top of the lowest floor including basements shall be at or above the <br />FPG. <br />(F) Standards for Manufactured Homes and Recreational Vehicles. Manufactured <br />homes and recreational vehicles to be installed or substantially improved on a <br />site for more than 180 days must meet one of the following requirements: <br />i. The manufactured home shall be elevated on a permanent foundation such <br />that the lowest floor shall be at or above the FPG and securely anchored to <br />an adequately anchored foundation system to resist flotation, collapse, and <br />lateral movement. This requirement applies to all manufactured homes to <br />be placed on a site; <br />a. outside a manufactured home park or subdivision; <br />b. in a new manufactured home park or subdivision; <br />c. in an expansion to an existing manufactured home park or subdivision; or <br />d. in an existing manufactured home park or subdivision on which a <br />manufactured home has incurred "substantial damage" as a result of a <br />flood. <br />ii. The manufactured home shall be elevated so that the lowest floor of the <br />manufactured home chassis is supported by reinforced piers or other <br />foundation elevations that are no less than 36 inches in height above grade and <br />be securely anchored to an adequately anchored foundation system to resist <br />flotation, collapse, and lateral movement. This requirement applies to all <br />manufactured homes to be placed on a site in an existing manufactured home <br />park or subdivision that has not been substantially damaged by a flood. <br />iii. Manufactured homes with fully enclosed areas formed by foundation and <br />other exterior walls below the flood protection grade (crawlspaces or under- <br />floor spaces) shall be designed to preclude finished living space and designed <br />to allow for the entry and exit of floodwaters to automatically equalize <br />hydrostatic flood forces on exterior walls as required for elevated structures in <br />Section (e) (1) (D). <br />iv. Flexible skirting and rigid skirting not attached to the frame or foundation of a <br />manufactured home are not required to have openings. <br />Page 24 of 31 <br />
