a. Designed and adequately anchoredto prevent flotation, collapse, or lateral movement;

b. Constructed of flood-resistant materials;

c. Constructed by methods andpractices that minimize flood damage;

d. Constructed with electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities that are designed and/or locatedso as to prevent water from entering oraccumulating within the components duringconditions of flooding;

3. New construction and substantialimprovements shall have the space below thelowest floor free of obstructions, or constructedwith breakaway walls[.], open wood latticework, or insect screening intended to collapse underwind and water loads without causing collapse, displacement, or other structural damage to the elevated portion of the building or supportingfoundation system. Such space shall not be usedfor human habitation, but shall be useable solelyfor vehicular parking, building access, limited

Machinery and equipment that service the building, such as furnaces, air conditioners, heat pumps, water heaters, washers, dryers, elevator lift equipment, electrical junction and circuit boxes, and food freezers areprohibited in such spaces. A breakaway wallshall have a safe design loading resistance ofnot less than ten and no more than twenty poundsper square foot. Breakaway wall collapse shallbe designed to result from a water load less thanthat which would occur during a base flood andthe elevated portion of the building shall bedesigned so as not to incur any structural damagefrom wind and water loads acting simultaneouslyduring a base flood.

4. Fill shall not be used for structuralsupport of buildings.

5. Manmade alteration of sand dunes shallnot increase potential flood damage.

G. The director shall be provided andshall maintain the following records:

a. Certification by an engineer orarchitect that the proposed structurecomplies with paragraphs 1 through 5 of thissubsection;

b. Certification by a structuralengineer or surveyor of the elevation (inrelation to mean sea level) of the bottom ofthe lowest structural member of the lowestfloor (excluding pilings or columns) of allnew and substantially improved structures,and information regarding whether suchstructures contain basements. FEMA's"elevation certificate" form, as amended,shall be used for the certification.7. Areas of a structure below the base

flood elevation may be used for parking vehicles, limited storage or storage, or access to the building, but not for human habitation. For suchareas that are five feet or more in height as measured from any point within such areas, the property owner shall enter into a "Non-conversionAgreement for Construction Within Flood HazardAreas" with the County. The agreement shall be in a form acceptable to the director and shall be
