§ 88-355-05. REHABILITATION

To guarantee the restoration, rehabilitation, and reclamation of mined areas, every applicant granted a mining permit must furnish a performance bond or other city-approved financial guarantee running to the city, in an amount established by the city plan commission at the time of special use approval. The amount of the performance bond or other approved financial guarantee must be adequate to ensure that the applicant, in restoring, reclaiming, and rehabilitating such land, will within a reasonable time meet the following minimum requirements:

88-355-05-A. SURFACE REHABILITATION

All excavation must be made either to a water-producing depth, such depth to be not less than 5 feet below the low water mark, or must be graded or backfilled with non-noxious, non-flammable, and non-combustible solids to ensure:

1.

That the excavated area will not collect and retain stagnant water; or

2.

That the surface of such area that is not permanently submerged is graded or backfilled as necessary to minimize erosion due to rainfall and that it will be in substantial conformity with the topography of the adjoining land area.

88-355-05-B. VEGETATION

Vegetation must be restored by appropriate seeding of grass or planting of shrubs or trees in all parts of the mining area.

88-355-05-C. BANKS OF EXCAVATION

The banks of all excavations not backfilled must be sloped to the water line at a slope that will not be less than 3 feet horizontal to one foot vertical, and the bank must be seeded and stabilized.
