<br />designed to automatically equalize hydrostatic flood forces <br />on the walls by allowing for the entry and exit of flood <br />waters, through providing a minimum of two (2) openings <br />(in addition to doorways and windows) having a total area <br />of one (1) square foot for every two (2) square feet of <br />enclosed area subject to flooding. The bottom of all such <br />openings shall be no higher than one (1) foot above grade. <br /> <br />2. Any enclosure below the elevated floor is used for storage <br />of vehicles and building access. <br /> <br />b. The foundation and supporting members shall be anchored and <br />aligned in relation to flood flows and adjoining structures so as to <br />minimize exposure to known hydrodynamic forces such as <br />buoyancy, current, waves, ice and floating debris. <br /> <br />c. All areas below the FPG shall be constructed of materials resistant <br />to flood damage. The top of the lowest floor (including basement) <br />and all electrical, heating, ventilating, plumbing and air <br />conditioning equipment and utility meters shall be located at or <br />above the FPG. Water and sewer pipes, electrical and telephone <br />lines, submersible pumps and other waterproofed service facilities <br />may be located below the FPG. <br /> <br />~ <br /> <br />3. Manufactured homes and recreational vehicles to be installed or <br />substantially improved on a site for more than one hundred eighty (180) <br />days must meet one (1) of the following anchoring requirements: <br /> <br />a. The manufactured home shall be elevated on a permanent <br />foundation such that the lowest floor shall be at or above the FPG <br />and securely anchored to an adequately anchored foundation <br />system to resist flotation, collapse and lateral movement. This <br />requirement applies to all manufactured homes to be placed on a <br />site; <br /> <br />1. Outside a manufactured home park or subdivision; <br /> <br />2. In a new manufactured home park or subdivision; <br /> <br />3. In an expansion to an existing manufactured home park or <br />subdivision; or <br /> <br />4. <br /> <br />In an existing manufactured home park or subdivision on <br />which a manufactured home has incurred "substantial <br />damage" as a result of a flood. <br /> <br />'-- <br />
