<br />(i) The lowest floor of the manufactured home is at or above the base
<br />flood elevation, or
<br />(ii) The manufactured home chassis is supported by reinforced piers
<br />or other foundation elements of at least equivalent strength that are no less
<br />than 36 inches in height above grade and be securely anchored to an
<br />adequately anchored foundation system to resist floatation, collapse, and
<br />lateral movement.
<br />(13) Notwithstanding any other provisions of Sec. 60.3, a community may
<br />approve certain development in Zones Al-30, AE, and AH, on the community's
<br />FIRM which increase the water surface elevation of the base flood by more
<br />than one foot, provided that the community first applies for a conditional
<br />FIRM revision, fulfills the requirements for such a revision as established
<br />under the provisions of Sec. 65.12, and receives the approval of the
<br />Administrator.
<br />(14) Require that recreational vehicles placed on sites within Zones
<br />Al-30, AH, and AE on the community's FIRM either
<br />(i) Be on the site for fewer than 180 consecutive days,
<br />(ii) Be fully licensed and ready for highway use, or
<br />(iii) Meet the permit requirements of paragraph (b) (1) of this section
<br />and the elevation and anchoring requirements for 'manufactured homes " in
<br />paragraph (c)(6) of this section. A recreational vehicle is ready for highway
<br />use if it is on its wheels or jacking system, is attached to the site only by
<br />quick disconnect type utilities and security devices, and has no permanently
<br />attached additions.
<br />(d) When the Administrator has provided a notice of final base flood
<br />elevations within Zones Al-30 and/or AE on the community's FIRM and, if
<br />appropriate, has designated AO zones, AH zones, A99 zones, and A zones on the
<br />community's FIRM, and has provided data from which the community shall
<br />designate its regulatory floodway, the community shall:
<br />(1) Meet the requirements of paragraphs (c) (1) through (14) of this
<br />section;
<br />(2) Select and adopt a regulatory floodway based on the principle that
<br />the area chosen for the regulatory floodway must be designed to carry the
<br />waters of the base flood, without increasing the water surface elevation of
<br />that flood more than one foot at any point;
<br />(3) Prohibit encroachments, including fill, new construction,
<br />substantial improvements, and other development within the adopted regulatory
<br />floodway unless it has been demonstrated through hydrologic and hydraulic
<br />analyses performed in accordance with standard engineering practice that the
<br />proposed encroachment would not result in any increase in flood levels within
<br />the community during the occurrence of the base flood discharge;
<br />(9) Notwithstanding any other provisions of Sec. 60.3, a community may
<br />permit encroachments within the adopted regulatory floodway that would result
<br />in an increase in base flood elevations, provided that the community first
<br />applies for a conditional FIRM and floodway revision, fulfills the
<br />requirements for such revisions as established under the provisions of Sec.
<br />65.12, and receives the approval of the Administrator.
<br />(e) When the Administrator has provided a notice of final base flood
<br />elevations within Zones Al-30 and/or AE on the community's FIRM and, if
<br />appropriate, has designated AH zones, AO zones, A99 zones, and A zones on the
<br />community's FIRM, and has identified on the community's FIRM coastal high
<br />hazard areas by designating Zones V1-30, VE, and/or V, the community shall:
<br />(1) Meet the requirements of paragraphs (c)(1) through (14) of this
<br />section;
<br />(2) Within Zones V1-30, VE, and V on a community's FIRM, (i ) obtain
<br />the elevation (in relation to mean sea level) of the bottom of the lowest
<br />structural member of the lowest floor (excluding pilings and columns) of all
<br />new and substantially improved structures, and whether or not such structures
<br />contain a basement, and (ii) maintain a record of all such information with
<br />the official designated by the community under Sec. 59.22(a)(9)(iii);
<br />(3) Provide that all new construction within Zones V1-30, VE, and V on
<br />the community's FIRM is located landward of the reach of mean high tide;
<br />(9) Provide that all new construction and substantial improvements in
<br />Zones V1-30 and VE, and also Zone V if base flood elevation data is
<br />available, on the community's FIRM, are elevated on pilings and columns so
<br />that (i) the bottom of the lowest horizontal structural member of the lowest
<br />floor (excluding the pilings or columns) is elevated toor above the base
<br />flood level; and (ii) the pile or column foundation and structure attached
<br />thereto is anchored to resist flotation, collapse and lateral movement due to
<br />the effects of wind and water loads acting simultaneously on all building
<br />components. Water loading values used shall be those associated with the base
<br />flood. Wind loading values used shall be those required by applicable State
<br />or local building standards. A registered professional engineer or architect
<br />shall develop or review the structural design, specifications and plans for
<br />the construction, and shall certify that the design and methods of
<br />
