<br /> <br />City of Arden Hills Appendix C: Regulatory Responsibilities and Developer Guidelines <br />WSB Project No. 3455-200 P a g e 3 <br /> <br />Floodplain Management <br />The City of Arden Hills currently does participate in the National Flood Insurance Program. A minimum <br />requirement for elevations of new structures is currently included in an existing City ordinance (ordinance <br />number 331), Chapter 13 of the City’s code. In areas not regulated by floodplain management control, the <br />lowest floor elevation shall be determined by an elevation of available flood information or placing the <br />lowest floor at a level at least three feet above the highest known water level. <br /> <br />Groundwater (Wellhead) Protection <br />The groundwater protection ordinance would establish overlay districts for wellhead protection areas and <br />any areas of spring activity or groundwater/surface water interaction. It would also address permitted uses <br />in the various protection zones and could be further developed to address abandonment of wells. <br /> <br />Wellhead Protection <br />Wetland protection is provided by the Minnesota Wetland Conservation Act administrated by Rice Creek <br />Watershed District acting as Local Government Unit (LGU). <br /> <br />Erosion Control <br />Arden Hills has adopted an erosion and sediment control ordinance (City Code Chapter 15). The <br />regulation establishes standards and specifications for conservation practices and planning activities <br />which minimize soil erosion and sedimentation. <br />Dr <br />a <br />f <br />t <br /> <br />11 <br />/ <br />2 <br />0 <br />/ <br />2 <br />0 <br />1 <br />7
