D.

Limitations on sites in regulatory floodways. No development, including, but not limited to, site improvements, and land disturbing activity involving fill or regrading, shall be authorized in the regulatory floodway unless the floodway encroachment analysis required in subsection 110-50.C. of this ordinance demonstrates that the proposed development or land disturbing activity will not result in any increase in the base flood elevation.

E.

Limitations on placement of fill. Subject to the limitations of this ordinance, fill shall be designed to be stable under conditions of flooding including rapid rise and rapid drawdown of floodwaters, prolonged inundation, and protection against flood-related erosion and scour. In addition to these requirements, if intended to support buildings and structures (Zone A only), fill shall comply with the requirements of the Florida Building Code.

(Ord. No. 2015-09, § 2(Exh. A), 9-21-2015; Ord. No. 2021-017, § 4, 11-3-2021)
