149 § 1007.050 DRAINAGE. (1) No land shall be developed or altered, and no use shall be permitted that results in increasing surface water runoff rates; causes unreasonable flooding; degrades water quality; or creates erosion or deposit of minerals on said land, adjacent properties, or water bodies in compliance with City Code Chapter 1011 and as required below. (2) For land disturbance and all construction, erosion control measures must be in place prior to the beginning of site work, e.g., grading, topsoil stripping, or construction. (a) The City may withhold inspections or suspend work on a site that does not have an approved grading plan or in-place erosion control measures. (b) The City may require financial security in the amount equal to the value of the project to ensure placement of erosion control measures. (3) The owner or contractor of any natural drainage improvement or alteration may be required by the City Engineer to obtain recommendations from the Minnesota Department of Natural Resources, the Soil Conservation District, U.S. Army Corps of Engineers, affected watershed district(s), and/or City Engineer. (4) On any slope in excess of eight (8) percent where, in the opinion of the City Engineer, the natural drainage pattern may be disturbed or altered, the City Engineer may require the applicant submit a grading plan and an erosion and sediment control plan prior to permit issuance. (5) Agricultural, residential, commercial, and industrial developments shall be in compliance with applicable recommendations of the City’s local water management plan as may be amended. (6) As part of a building permit application in which new structures or building footprint expansion of existing structures are proposed, a site survey showing proposed grading, drainage, erosion control, and building pad elevation(s) must be submitted to the City along with a certification by a registered land surveyor or engineer that they are consistent with the grading and drainage plan approved with the final plat or site plan. (7) Prior to issuance of an occupancy permit, the person or entity who developed, graded and constructed improvements upon the property for which the occupancy permit is requested, must submit certification by a registered land surveyor or engineer that the final grading, drainage and building pad elevations are consistent with the approved grading and drainage plan approved with the subdivision or site plan. If no such City approved drainage and grading plan for the entire subdivision exists, that such person or entity must represent that the grading, drainage and building pad elevations are consistent with the requirements of City Code Section 1007.050 (1) through Section 1007.050(5).
