§ 62-4399. Specific standards for individual land use types.

(a)

In addition to the specific standards described in this section, the following land uses shall be revegetated in accordance with the standards set forth in divisions 2 and 3 of this article:

(1)

Agricultural lands. Lands reclaimed for agricultural use shall be:

a.

Sufficiently level and free of holes, gullies and washouts to permit safe operation of conventional agricultural equipment.

b.

Settled and firmed to the extent that the land will support conventional agricultural equipment and that livestock will be able to walk on the surface of the land.

(2)

Lakes. Lands reclaimed as lakes shall meet the following standards in addition to those outlined within subsection 62-4398(3), pertaining to topography and drainage. A vegetated littoral zone below mean high-water shall be established for lakes. A mixture of native vegetation shall be established by natural colonization, by inoculation or by planting within 12 months after the excavation activity is completed. Where planting is used, plantings shall be on three-foot centers and shall consist of species found in subsection (b) of this section. The applicant shall provide the director with a quarterly report, including photographs of the littoral zone, for a period of two years after the lake has been completed. At the end of this two-year period, if the plants have not attained 80 percent coverage of the required planted area, replanting must occur to attain the appropriate coverage. Herbicides approved for aquatic use may be applied to control undesirable aquatic plants.

a.

Side slopes shall be not steeper than five feet horizontal to one foot vertical to a mean water depth of five feet. Slopes deeper than five feet shall be no steeper than two to one.

b.

No portion of the lake shall exceed 35 feet in depth below the mean water level, unless a St. Johns River Water Management District permit is obtained for the additional depth and the following information is provided to and approved by the board of county commissioners:

1.

Adequate assurance that no adverse impact will occur to adjacent resources of particular concern;

2.

Representative soil profiles of the borrow location to a depth of at least five feet below the proposed final depth of the lake.

3.

Representative data on the water levels, chloride concentrations, and head calculations from permanent shallow and deep well monitoring stations including well locations and construction logs. If the additional depth is approved, periodic monitoring of these parameters will be required as necessary.

4.

Assurance that the hydrologic conditions will not be adversely impacted so as to cause a connection between aquifers.

5.

A model of the effects of groundwater withdrawal on the surrounding area if the project is not providing a rim ditch to recharge the water withdrawn during excavation.

6.

The applicant shall immediately notify the county and the St. Johns River Water Management District in writing of any previously submitted information that is later discovered to be inaccurate.

7.

If unanticipated significant adverse impacts occur to resources of particular concern, the county may revoke the permit in whole or in part to curtail or abate further adverse impacts, unless the impacts can be mitigated by the applicant. It shall be the financial responsibility of the applicant to curtail or abate any adverse impacts or, if the adverse impact is caused by a breach of a permit condition, to restore the resource to a condition that existed prior to the breach of the condition.

8.

A bond may be required by the board as necessary to provide adequate assurance that no adverse impacts will occur to adjacent resources. The bond shall be set in an amount of the costs reasonably calculated to correct or repair a reasonably foreseeable violation of the conditions of approval imposed by the board or the St. Johns River Water Management District.

c.

For the purposes of establishing an area that will sustain fish and wildlife and to provide for water quality maintenance, all lakes shall include a littoral zone in accordance with the following design criteria:

1.

When lakes are utilized within a stormwater management system and pretreatment of the stormwater is provided prior to entering the lake, a littoral zone comprising 25 percent of the total surface area of the lake at mean water level shall be provided.

2.

When lakes are utilized within a stormwater management system and pretreatment of the water is not provided prior to entering the lake, a littoral zone comprising 30 percent of the total surface area of the lake at mean water level shall be provided.

3.

When lakes are not utilized within a stormwater management system, and stormwater is not entering the lake, a littoral zone comprising 15 percent of the total lake area at mean water level shall be provided.

In some cases the director may allow the area covered by native littoral vegetation to be established off the site when this would enhance an existing or created wildlife habitat and when this would not adversely affect the water quality of the lake.

(3)

Wildlife habitats. Except where altered lands are reclaimed to agricultural lands, wetlands or lakes, they shall be reclaimed to wildlife habitat with native species typical of this area of the state.

(b)

Plant species suitable for and sometimes available from nurseries for littoral zone plantings of private lakes are as follows:

Common Name	Scientific Name
Arrowhead/Duck-potato	Sagitteria latifolia
Blue flag iris	Iris virginicus
Bulrush	Cyperus, Scirpus spp.
Climbing aster	Aster carolinianus
Coinwort/Water pennywort	Hydrocotyle umbellata
Cordgrass	Spartina bakeri
Cypress	Taxodium spp.
Golden canna	Canna flaccida
Maidencane	Panicum hemitomon
Pickerelweed	Pontederia lanceolata
Rushes	Juncus, Eleocharis spp.
Spatterdock/Yellow pond lily	Nuphar luteum
Sedges	Cyperus spp.
Water-shield/Dollar bonnet	Brasenis schreberi
Water tupelo/Cotton gum	Nyssa spp.
White water lily	Nymphaea odorata

 

Other plant species may be acceptable for littoral zone plantings. Species other than those listed in this subsection must be approved by the office of natural resources management prior to planting.
