The applicant shall abide by one of the two following operating and land rehabilitation practices.
(A) Excavations resulting in the accumulation of substantial water areas after rehabilitation must meet the following requirements.
(1) The water depth must not be less than three feet measured from the low water mark.
(2) All banks shall be sloped to the water line at a slope which shall not be steeper than four feet horizontal to one foot vertical.
(3) All banks shall be sodded, seeded with erosion retardant seed mixtures and mulches or surfaced with soil of a quality at least equal to the topsoil of land areas immediately surrounding and to a depth of at least six inches.
(4) Topsoil as required by division (A)(3) above shall be planted with trees, shrubs, legumes or grasses upon the parts of the area where revegetation is possible; and as recommended by the soil conservation plan.
(5) Slopes on boundary areas shall not be steeper than four feet horizontal to one foot vertical. No slope shall begin closer than 50 feet to any property line.
(6) Maximum depth of the excavation may be requested by the Council.
(B) Excavations not resulting in water areas after rehabilitation but which must be graded or backfilled, shall meet the following requirements.
(1) Grading or backfilling shall be made with nonnoxious, nonflammable and noncombustible solids which will not cause leaching problems into groundwater systems.
(2) The graded or backfilled area shall not collect or permit stagnant water to remain therein.
(3) The peaks and depressions of the area shall be reduced to a gently rolling topography of less than a five to one slope in substantial conformity to the land area immediately surrounding and which will minimize erosion due to rainfall.
(4) The graded or backfilled area shall be sodded, seeded with erosion retardant seed mixtures and mulches or surfaced with soil of a quality at least equal to the topsoil of land areas immediately surrounding, and to a depth of at least 12 inches.
(5) The topsoil as required by division (B)(4) above shall be planted with trees, shrubs, legumes or grasses upon the parts of the area where revegetation is possible, consistent with the recommendations of the soil conservation service.
(6) New slopes on boundary areas shall not be steeper than four feet horizontal to one foot vertical. No slope or bank shall begin closer than 50 feet to the property line.
(7) The maximum depth of excavation may be regulated by the Council.
