660.15   DRAINAGE, FILLING, GRADING, EXCAVATING.
   (a)   No owner, occupant or person in charge of any lot or parcel of ground shall cause or permit water to accumulate thereon and become stagnant, permit culverts, drains or natural watercourses thereon to become obstructed or cause or permit any putrid or unsanitary substance to accumulate thereon.
   (b)   No owner, lessee, occupant or person in charge of any premises in the City shall dump, place or deposit or permit others to dump, place or deposit any material upon land in the City for purposes of filling or refilling any land without first applying to the City for a permit to place nonorganic material upon land in the City for the purpose of filling or attaining a certain grade level.
   (c)   No owner, lessee, occupant or person in charge of any premises shall permit dumping of any masonry, lumber or other nonorganic material upon his or her premises unless such premises are graded and leveled at the end of each day of dumping and unless all holes or voids in the surface of the lot or land are filled with sand, dirt or gravel.
    (d)   No owner, lessee, occupant or person in charge of any premises where such material is placed but not graded and/or filled as required herein shall fail to comply with an order to remedy the condition within twenty-four hours of receiving a notice of such violation from the City.
   (e)   No owner, lessee, occupant or person in charge of any premises shall cause, allow or permit any excavation or grading where the ground elevation is changed by more than one foot, or where the proposed grading or excavation would result in alterations or changes to existing drainage courses, ditches, swales or other waterways, without first obtaining a permit for such operation. Application for such permits shall contain information showing the existing grade levels, the proposed grade levels and, in the case of changes to swales, drainage courses or other waterways, the existing course of such waterway, the proposed change in this waterway and sufficient topographic information to determine the change in the water run-off characteristics that this proposed change would cause. In no case shall a permit be issued where the excavation or grading operations would produce a slope steeper than 2:1 without specialized retainage designs being used, nor shall a permit be issued where the change in the grade and/or watercourse would result in increased downstream run-off beyond the capacity of the existing drainage way, ditch or other waterway to handle this run-off, nor where this grading or excavating would result in increased erosion or sedimentation to the detriment of the downstream property owner. The Director of Public Service or his/her designee shall be responsible for the review of permit applications and for the issuance of such permits.
   (f)   The owner, occupant, lessee or person in charge of any lot or parcel wherein grading, filling or excavating has occurred and which exceeds 5,000 square feet shall re-establish the vegetation or ground cover which was removed as a part of the operation. Such re- establishment of ground cover shall occur within 120 days after the date on which the original ground cover was removed, or, if construction is progressing on a continuing basis, immediately after the cessation of such construction. Reseeding shall be done in a manner that will provide permanent ground cover of sufficient density to preclude erosion and/or increased sedimentation on downstream parcels.
   (g)   Whoever violates any of the provisions of this section is guilty of a misdemeanor of the first degree. A separate offense shall be deemed committed each day during or on which a violation occurs or continues.
