<br />(2) Require the appllcatlon of the
<br />>andards in paragraphs (a) (2), (3),
<br />D, (5) and (6) of this section to devel-
<br />pment within Zone A on the commu.
<br />Ity's FHBM or FIRM;
<br />(3) Require that all new subdivision
<br />roposals and other proposed develop-
<br />lents (including proposals for manu-
<br />Lctured home parks and subdivisions)
<br />reater than 50 lots or 5 acres, which-
<br />"er Is the lesser, include within such
<br />roposals base flood elevation data;
<br />(4) Obtain, review and reasonably
<br />tilize any base flood elevation and
<br />oadway data available from a Feder-
<br />~. State. or other source, including
<br />ata develo'ped pursuant to paragraph
<br />))(3) of this section, as criteria for re-
<br />ulring that new construction, sub-
<br />;antial improvements, or other devel-
<br />pment in Zone A on the community's
<br />HBM or FIRM meet the standards in
<br />aragraphs (c)(2), (c)(3), (c)(5), (c)(6),
<br />:)(12), (c)(14), (d)(2) and (d)(3) of this
<br />,ctlon;
<br />(5) Where base flood elevation data
<br />ce utilized, within Zone A on the
<br />lmmunity's FHBM or FIRM:
<br />(i) Obtain the elevation (In relation
<br />) mean sea level) of the lowest floor
<br />neluding basement) of all new' and
<br />Ibstantially improved structures, and
<br />(Ii) Obtain, If the structure has been
<br />oodproofed in accordance with para-
<br />",ph (c)(3)(1iJ of this section, the ele,
<br />!.tion (in relation to mean sea level)
<br />) which the structure was flood-
<br />roofed, and
<br />(ili) Maintain a record of all such In-
<br />Irmation with the official designated
<br />v the community under i 59.22
<br />,)(9)(ii1);
<br />(6) Notify, in riverine situations, ad-
<br />.cent communities and the State Co-
<br />cdinating Office prior to any alter.
<br />;ion or relocation of a watercourse,
<br />ld submit copies of such notifications
<br />. the Administrator;
<br />(7) Assure that the flood carrying ca-
<br />.city within the altered or relocated
<br />:>rtion of any watercourse is main-
<br />,ined;
<br />(8) Require that all manufactured
<br />omes to be placed within Zone A on a
<br />Immunity's FHBM or FIRM shall be
<br />LStalled using methods and practices
<br />hlch minimize flood damage. For the
<br />lrposes of this requirement, manu-
<br />.ctur~d homes must be elevated and
<br />
<br />anchored to resist flotation, collapse,
<br />or lateral movement. Methods of an.
<br />choring may include, but are not to be
<br />limited to, use of over-the-top or frame
<br />ties to ground anchors. This require-
<br />ment is In addition to applicable State
<br />and local anchoring requirements for
<br />resisting wind forces.
<br />(c) When the Administrator has pro-
<br />vided a notice of final flood elevations
<br />for one or more special flood hazard
<br />areas on the community's FIRM and,
<br />If appropriate, has designated other
<br />special flood hazard areas without
<br />base flood alevations on the communi-
<br />ty's FIRM, but has not identified a
<br />regulatory floodway or coastal high
<br />hazard area, the conununity shall:
<br />(1) Require the standards of para-
<br />graph (b) of this section within all AI-
<br />30 zones, AE zones, A zones, AH zones,
<br />and AO zones, on the community's
<br />FIRM;
<br />(2) Require that all new construction
<br />and substantial improvements of resi-
<br />dential structures within Zones AI-30,
<br />AE and AH zones on the community's
<br />FIRM have the lowest fioor (including
<br />basement) elevated to or above the
<br />base flood level, unless the community
<br />Is granted an exception by the Admin-
<br />istrator for the allowance of -base-
<br />ments in accordance with ~ 60.6 (b) or
<br />(c);
<br />(3) Require that all new construction
<br />and substantial improvements of non.
<br />residential structures within Zones
<br />AI-30, AE and AH zones on the com-
<br />munity's firm (i) have the lowest floor
<br /><including basement) elevated to or
<br />above the base flood level or, (Ii) to,
<br />gether with attendant utility and sani-
<br />tary facilities, be designed so that
<br />below the hase flood level the struc.
<br />ture Is watertight with walls substan-
<br />tlally' impermeable to the passage of
<br />water and with structural components
<br />having the capability of resisting' hy-
<br />drostatic and hydrodynamic loads and
<br />effects of buoyancy;
<br />(4) Provide that where a non-resi-
<br />dential structure Is intended to be
<br />made watertight below the base flood
<br />level, (1) a registered professional engi-
<br />neer or architect shall ,develop and/or
<br />review structural design, specifica-
<br />tions, and plans for the construction,
<br />and shall certify that the design and
<br />methods of construction are in accord-
