                         7.5(2).

                  b. Shall be anchored to prevent flotation, collapse, or lateral
                         movement of the structure resulting from hydrodynamic and
                         hydrostatic loads, including the effects of buoyancy and shall be
                         constructed with methods and materials resistant to flood damage.

                  c. Shall be constructed with electrical, heating, ventilation, plumbing

                         accumulating within the components during conditions of flooding.

                  d. In A Zones, obtain, review and utilize any flood data available from

                         (2).

                  c. In AO Zones with no elevations specified, shall have the lowest
                         floor, including basement, meet the standards in s. 5.3(1).

(3) A nonconforming historic structure may be altered if the alteration will not
      preclude the structures continued designation as a historic structure, the alteration
      will comply with s. 3.3(1), flood resistant materials are used, and construction
      practices and floodproofing methods that comply with s. 7.5 are used. Repair or
      rehabilitation of historic structures shall be exempt from the development standards
      of s. 6.1(2)(h)1if it is determined that the proposed repair or rehabilitation will not

                                                                     19
