(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 terebinthfolius
Castor bean – Ricinus communis
Common papaya – Carica papaya
Common snakeplant – Sanseviera trifasciata
Day jessamine – Cestrum diurnum
Hunters robe – Raphidophora 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. spartinae
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 Florida Statutes § 380.04, as development or applies for a development permit as defined in Florida Statutes § 380.031, 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.
