C. Additional Requirements for the Issuance of a Variance 1.

All new construction and substantial improvements in zones V1-30 and VE(V if base flood elevation data is available)on the community's FIRM shall be elevated on pilings and columns so that: 1. Elevation: a) Residential Buildings.The bottom of the lowest horizontal structural member of the lowest floor (excluding the pilings or columns) is elevated one foot or more above the base flood level. b) Nonresidential buildings.The bottom of the lowest horizontal structural member of the lowest floor (excluding the pilings or columns) is elevated one foot or more above the base flood level or meets the elevation requirements of ASCE 24,whichever is higher; and 2. The pile or column foundation and structure attached thereto is anchored to resist floatation,collapse and lateral movement due to the effects of wind and water loads acting simultaneously on all building components. Wind and water loading values shall each have a one percent chance of being equaled or exceeded in any given year(100-year mean recurrence interval).A registered professional engineer or architect shall develop or review the structural design,specifications and plans for the construction,and shall certify that the design and methods of construction to be used are in accordance with accepted standards of practice for meeting the provisions of this subsection. B. Obtain the elevation (in relation to mean sea level)of the bottom of the lowest structural member of the lowest floor(excluding pilings and columns)of all new and substantially improved structures in zones V1-30, VE, and V on the community's FIRM and whether or not such structures contain a basement.The Floodplain Administrator shall maintain a record of all such information. C. All new construction within zones V1-30,VE, and V on the community's FIRM shall be located landward of the reach of mean high tide. 18
