§ 42-126. Non-residential construction.

New construction or substantial improvement of any commercial, industrial, or non-residential structure (including manufactured homes) shall have the lowest floor elevated no lower than one foot above the level of the base flood elevation. Should solid foundation perimeter walls be used to elevate a structure, openings sufficient to facilitate the unimpeded movements of flood waters shall be provided in accordance with section 42-129. No basements are permitted. Structures located in A-zones may be floodproofed in lieu of elevation provided that all areas of the structure below the required elevation are watertight with walls substantially impermeable to the passage of water, using structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effect of buoyancy. A registered, professional engineer or architect shall certify that the standards of this subsection are satisfied. Such certifications shall be provided to the official as set forth in sections 42-70(7) and 42-70(9). A variance may be considered for wet-floodproofing agricultural structures in accordance with the criteria outlined in section 42-167 of this chapter. Agricultural structures not meeting the criteria of section 42-167 must meet the non-residential construction standards and all other applicable provisions of this chapter. Structures which are floodproofed are required to have an approved maintenance plan with an annual exercise. The maintenance plan must be approved by the local administrator and notification of the annual exercise shall be provided to same.
