(A) New construction, substantial improvements and all other development, including fill, shall be prohibited within zones numbered A1-30 on the FIRM, except where it is demonstrated to the Zoning Administrator that the cumulative effect of the proposed development when combined with all other existing and anticipated development will not harmfully increase the water surface elevation of a base flood. In determining whether a harmful increase will occur, compliance with state law, shall be required; provided that, the allowable increase shall not exceed one foot. Zones A1-30 on the FIRM shall be considered to be the floodway.
(B) The uses of land permitted in an underlying zoning district shall not be construed as being permitted within the floodway, except upon compliance with the provisions in this section.
