(A) No land shall be developed or altered and no use shall be permitted that results in surface or stormwater run-off causing or with the potential to cause unreasonable flooding, erosion or deposit of materials on adjacent properties or waterbodies. The run-off shall be properly channeled into a stormwater management facility that is consistent with the stormwater management and erosion and sediment control requirements of Ch. 158 of this code. Any increase in run-off rate or volume as a result of the developed portion of a property shall achieve at least the minimum requirements of Ch. 158 of this code.
(B) The Zoning Administrator, upon inspection of any site that has created drainage problems, or could create drainage problems with proposed new development, may require the owner of a site or the contractor of the development to complete a grading plan and apply for a grading permit.
(C) The owner or contractor of any natural drainage improvement or alteration may be required by the Zoning Administrator to obtain recommendations from the state’s Department of Natural Resources, the county’s Soil Conservation District, the affected Watershed District and/or the City Engineer, as well as obtaining a grading permit.
(D) On any slope in excess of 13% where, in the opinion of the Zoning Administrator, the natural drainage pattern may be disturbed or altered, the Zoning Administrator may require the applicant to submit both a grading plan and a soil conservation plan prior to applying for a building permit.
