In coastal high hazard areas, development activities other than buildings and structures shall be permitted only if also authorized by the appropriate federal, state, or local authority; if located outside the footprint of, and not structurally attached to, buildings and structures; and if analyses prepared by qualified registered design professionals demonstrate no harmful diversion of floodwaters or wave runup and wave reflection that would increase damage to adjacent buildings and structures. Such other development activities include but are not limited to:
(1) Bulkheads, seawalls, retaining walls, revetments, and similar erosion control structures;
(2) Solid fences and privacy walls, and fences prone to trapping debris, unless designed and constructed to fail under flood conditions less than the design flood or otherwise function to avoid obstruction of floodwaters; and
(3) On-site sewage treatment and disposal systems defined in 64E-6.002, Florida Administrative Code, as filled systems or mound systems.
