(a) To guarantee the restoration, rehabilitation and reclamation of a mined-out area, every applicant granted a mining permit as herein provided shall furnish a performance bond running to the City, in an amount of not less than one thousand dollars ($1,000) and not more than ten thousand dollars ($10,000) as a guarantee that such applicant, in restoring, reclaiming and rehabilitating such land, shall within a reasonable time and to the satisfaction of the Municipal Planning Commission meet the following minimum requirements.
(b) All excavation shall be made either to a water-producing depth, such depth to be not less than five feet below the low water mark, or shall be graded or backfilled with non-noxious, noninflammable and noncombustible solids, to secure:
(1) That the excavated area shall not collect and permit to remain therein stagnant water; or
(2) That the surface of such area which is not permanently submerged is graded or backfilled as necessary so as to reduce the peaks and depressions thereof, so as to produce a gently running surface that will minimize erosion due to rainfall and which will be in substantial conformity to the adjoining land area.
