(1) Site
alteration shall be limited to 10% of the total site size, and installation of
nonpermeable surfaces shall not exceed 50% of any such area. However, a minimum
of 2, 500 square feet may be altered on any permitted site.
(2) Except for roads, any nonpermeable
surface greater than 20, 000 square feet shall provide for release of surface
run off, collected or uncollected, in a manner approximating the natural
surface water flow regime of the area.
(3) Soils exposed during site alteration
shall be stabilized and retention ponds or performance equivalent structures or
systems maintained in order to retain run off and siltation on the construction
site. Restoration of vegetation to site alteration areas shall be substantially
completed within 180 days following completion of a development. Revegetation
shall be accomplished with pre-existing species or other suitable species
except that undesirable exotic species (see list below) shall not be replanted
or propagated.
Australian pine - Casuarina equisetifolia
Bishopwood - Bischofia javanica
Brazilian pepper (holly) - Shinus terebinthifolius
Castor bean - Ricinus communis
Common papaya - Carica papaya
Common snakeplant - Sanseviera trifasciata
Day jessamine - Cestrum diurnum
Hunters robe - Rhaphidophora aurea
Melaleuca (cajeput) - Melaleuca leucadendra
Queensland umbrella tree - Schefflera actinophylla
Trailing wedelia - Wedelia trilobata
(4) No mangrove trees or salt marsh grasses
shall be destroyed or otherwise altered. Plants specifically protected in this
regulation include:
Red mangrove - Rhizophora mangle
Black mangrove - Avicennia nitida
White mangrove - Laguncularia racemosa
Needlerush - Juncus roemerianus
Salt cordgrasses - Spartina alterniflora, S. patens, S.
cynosuroides, S. spartina
Seashore saltgrass - Distichlis spicata
(5) Fill areas and related dredge or borrow
ponds shall be aligned substantially in the direction of local surface water
flows and shall be separated from other fill areas and ponds by unaltered areas
of vegetation of comparable size. Dredge or borrow ponds shall provide for the
release of storm waters as sheet flow from their downstream end into unaltered
areas of vegetation. Access roads to and between fill areas shall provide for
the passage of water in a manner approximately the natural flow regime and
designed to accommodate the 50 year storm. Fill areas and related ponds shall
not substantially retain or divert the total flow in or to a slough or strand
or significantly impeded tidal action in any portion of the estuarine
zone.
(6) Man-made lakes, ponds, or
other containment works shall be constructed with a maximum slope of 30 degrees
to a depth of six feet of water. Whenever mineral extraction is completed in
new quarrying lakes, shoreline sloping, revegetation and disposal of spoils or
tailings shall be completed before abandonment. Existing quarrying lakes are
exempt from this provision, except that whenever any person carries out any
activity defined in Section 380.04, F.S., as development or applies for a
development permit as defined in Section 380.031, F.S., to develop any existing
quarrying lake area, these regulations shall apply.
(7) Finger canals shall not be constructed in
the Critical Area.
(8) This rule
shall not apply to site alterations undertaken in connection with the
agricultural use of land or for the conversion of land to agricultural
use.
